Situational Awareness and Operations

No comments

A five -alarm fire on Sunday March 10, 2013 resulted in several firefighters nearly losing their lives, when a resulting backdraft or smoke explosion rapidly occurred during fire suppression operations in a mixed use occupancy building in Harrison, New Jersey.

According to published reports, the rapidly extending fire likely started in the kitchen of a Mexican restaurant on the 600 block of Frank E. Rogers Avenue before it quickly spread and engulfed the entire building, and the adjacent exposure.

Reported information states Investigators have stated this is the second time a fire has broken out in the restaurant.

Reading the Building and Maintaining focused Situational Awareness is Mission Critical. What do you see in this street view and what impact would it have on operations? Google Maps image capture

Fire Department officials have initially classified this as a backdraft as first published in the media. “The unfortunate thing with a back-draft is that initially there’s heavy smoke in the building,” said Captain Robert Gillen of the Harrison Fire Department, “all you need is an entrance of more oxygen and there’s a massive explosion.” Two of the firefighters had more extensive injuries than the other three.

A series of video screen captures has been developed to clearly depict the sequence of events that were apparent as the smoke conditions between the fire building and exposure occupancy rapidly and in a quick succession of seconds went from showing normal fire suppression operational smoke profiling to what would become a backdraft [like] explosion or smoke explosion affecting numerous operating interior and fireground companies.

The need to maintain concise and focused situational awareness during all phases and stages of fireground operations is imperative to identify conditions when subtle or rapidly changing situations and environments may present an opportunity to communicate and react accordingly.

It’s readily apparent that the rapidness of the smoke changes and pressures that can be seen dramatically sequenced into the explosion stage with little chance to initiate actions.

It should be noted that the brief series of frames in the video can not fully ascetain if this is truly a backdraft explosion or a smoke explosion. There are sublte differences in the intiating fire dynamics and sequence of events interior events.

The importance of understanding the building, the occupancy risk and the manner in which fire and the products of combustion typically travel within similar or unique occupancies and the manner in which commanders and officers monitor and maintain keen situ-awareness.

Recognizing fire behavior indicators and monitoring fire dynamics within the fire compartment and building envelope and the impact of fire suppression actions and intervention and external environmental factors require frequent monitoring and peridic status reports to maintain fluid and continuous assessment of conditions that may influence the conduct of operations.

This event continues to reinforce the need to never allow complacency creep to occur regardless how predictable or unchanging the commonality of the operations are being undertaken or conducted, in similar fashion to past successes in comparable occupancies and structures.

Reading the Fire

Before watching the video (or watching it again if you have already seen it), download and print the B-SAHF Worksheet. Using the pre-fire photo (figure 1) and observations during the video, identify key B-SHAF indicators that may have pointed to potential for extreme fire behavior in this incident.

Important! Keep in mind that there is a significant difference between focusing on the B-SAHF indicators in this context and observing them on the fireground. Here you know that an explosion will occur, so we have primed the pump so you can focus (and are not distracted by other activity).

Backdraft or Smoke Explosion

While smoke explosion and backdraft are often confused, there are fairly straightforward differences between these two extreme fire behavior phenomena. A smoke explosion involves ignition of pre-mixed fuel (smoke) and air that is within its flammable range and does not require mixing with air (increased ventilation) for ignition and deflagration. A backdraft on the other hand, requires a higher concentration of fuel that requires mixing with air (increased ventilation) in order for it to ignite and deflagration to occur. While the explanation is simple, it may be considerably more difficult to differentiate these two phenomena on the fireground as both involve explosive combustion.

  1. Did you observe any indicators of potential backdraft prior to the explosion?
  2. Do you think that this was a backdraft?
  3. What leads you to the conclusion that this was or was not a backdraft?
  4. If you do not think this was a backdraft, what might have been the cause of the explosion?

Worcester Cold Storage Tragedy

On December 3, 1999, a five-alarm fire at the Worcester Cold Storage & Warehouse Co. building claimed the lives of six brave firefighters who responded to the call. These six heros, The Worcester 6, sacrificed their lives to try and rescue two individuals who were believed to be trapped inside the inferno. May the Worcester 6 always be remembered; “Fallen Heroes Never Forgotten.”

The Same Mistakes: Newspaper Reports Common Issues Affecting Fire Operations

No comments

Firefighters rush into a burning commercial building with too-small hoses and insufficient water. The commander can’t reach them because the captain forgot his radio. Backup crews aren’t sure where to go or what to do. Confusion reigns as the building’s truss roof collapses in an explosion of flames.

This reads like the playbook from the deadly Sofa Super Store fire in June 2007, but it’s not. These dangerous missteps occurred at a March 1 blaze on Daniel Island, according to an internal report obtained by The Post and Courier.

This blaze at an office building on Daniel Island on March 1 of this year has led to the demotion of a Charleston fire captain and controversy within the ranks.

They occurred despite nearly four years of intensive and expensive efforts to instill a culture of safety in the Charleston Fire Department.

What’s more, the commander in charge that day — a man repeatedly faulted in the in-house review of the blaze — was recently promoted to a top position in the department. And that’s causing some dissension in the ranks.

City fire officials stand behind their promotion of Troy Williams to battalion chief, and they said the portion of the draft report that leaked to the newspaper is incomplete, unfair, unofficial and riddled with inaccuracies.

Fire Chief Thomas Carr acknowledged problems at the fire, which gutted a two-story office building at 899 Island Park Drive. That’s why he authorized a six-member committee of firefighters to conduct what’s known as a critical incident review. But Carr said he rejected the resulting draft report when it landed on his desk six weeks ago because it had errors and failed to live up to its intended purpose, which is to be an educational tool, not an instrument for blame.

The 12-page portion obtained by the The Post Courier newspaper describes “major” violations of policy and assigns blame for those mistakes. It raises questions about the handling of the blaze, the effectiveness of the training firefighters have received and the integrity of the promotion process.

It also highlights the continuing conflict between the department’s hard-charging past and its new, risk-sensitive methods.

On Friday, December 3, 1999, at 1813 hours, the Worcester, Massachusetts Fire Department dispatched Box 1438 for 266 Franklin Street, the Worcester Cold Storage and Warehouse Co. A motorist had spotted smoke coming from the roof while driving on an adjacent elevated highway. The original building was constructed in 1906, contained another 43,000 square feet. Both were 6 stories above grade. The building was known to be abandoned for over 10 years.   

   

The Argument for European, North American Unification

No comments

While doing some research on UK and US Strategic Leadership and Operational issues, I came across an article published on FireChief .com on April 28, 2011 and written by By Glenn Bischoff titled: The Argument for European, North American Unification. After reading through the piece, I thought this had some interesting connotations worthy of reposting on CommandSafety.com.

The information contained in the article points out the highlights from John Chubb, a battalion chief for the Dublin Fire Brigade, who spoke on the topic at the 2011 Fire Department Instructors Conference (FDIC) held in Indianapolis. Take some time to read the excerpt here and follow the link for the complete article on FireChief.com HERE. I’m certain there can be some interesting dialog that can evolve from it.

Both the European and North American fire services would benefit greatly from a unified approach to firefighting for a very simple and straightforward reason: the former is well-schooled in the theories of fire dynamics, while the latter is expert on fireground tactics. So said John Chubb, a battalion chief for the Dublin Fire Brigade, who spoke on the topic last month at the Fire Department Instructors Conference (FDIC) held in Indianapolis.

Indeed, many sound North American tactics — such as technical rescue, hazmat response, positive pressure ventilation, tactical ventilation and forcible entry techniques, particularly the use of the Halligan tool — largely are being ignored by European fire departments, according to Chubb. “There is a level of ignorance towards the way in which North American departments operate, and even a level of arrogance,” Chubb said. “People in Europe feel that we have superior firefighting technology and a superior [knowledge of] firefighting science in the average firefighter. But I would suggest that such a belief is very close-minded.”

Chubb added that such beliefs are fueled by misconceptions about the number of line-of-duty deaths in North America, particularly in the United States, which at first glance are considerably higher than they are in Europe. “When you drill down into the American statistics, however, you find that they are taken from a much broader spectrum of deaths than the European statistics, particularly the United Kingdom,” he said.

“In other words, if you went home from work [in the U.S.] and 12 hours later you had a cardiac event, that would be associated with your job. That wouldn’t happen in the U.K.”

Chubb cited a couple of examples during the session where an application of North American tactics might have saved lives. In one, a fire started on the 14th floor of an apartment building in the U.K., when a tea light that had been left burning on top of a television set in a bedroom had burned through its container. One of the occupants awoke to the smell of smoke and raced to the kitchen to get a towel, thinking that he could somehow smother the fire. Unfortunately, he couldn’t get back to the bedroom where he had left his girlfriend because the smoke and heat was too oppressive. By this time, he also couldn’t find his way to the front door of the apartment, so he opened a window to call for help. Passerby placed the emergency call.

Two pumpers arrived to the incident about three minutes after the call was received, Chubb said. What they found when they arrived was a building that had no sprinkler system. It did have a hydrant/standpipe, but that was padlocked because of previous vandalism. Unfortunately, neither of the pumpers was equipped with a bolt cutter. Two firefighters raced to the 14th floor and kicked in the door of the apartment. When they were told that the girlfriend still was inside the unit, they decided to perform a rescue — despite having no water.

Fire/EMS Safety, Health and Survival Week 2011, Day Seven; Fire Fighter, Fire Officer and Command Training and Preparedness

3 comments

Preparing for the Mayday Event; Not a matter of IF, But a Question of When… Are you ready? Are you Prepared?

As the official Fire/EMS Safety Week 2011 begins to wind down, in many stations around the country this weekend is dedicated to training, drills and evolutions dedicated toward the many facets and functional elements that focus upon Surviving the Fire Ground – Fire Fighter, Fire Officer and Command Preparedness. 

The Safety Planning and Resource Aid and Guide published by the IAFC and IAFF (HERE) and the direct link here 2011 Planning and Resource Aid for Training Deliveries provided resources and planning templates and suggested training and activities to support the focus and emphasis on fire ground survival, increased focus on firefighter operations and mayday elements crucial to company integrity, firefighter safety and operational excellence.

Being ready for a mayday (mentally and physically), self-rescue and self-survival training and methodologies are mission critical when engaging in structural firefighting operations. Proficiencies, capabilities, rigor, demeanor and performance must be orchestrated in a manner that requires optimum execution of required actions and engagements to enable a successful outcome to a reported single or multiple mayday calls.

On a crisp fall day in October, 2009 two fires, both in residential occupancies but over 350 miles apart had similar operational needs, deployment and fire suppression and rescue engagement consistent with modern firefighting practices, methodologies and expectations.

In one, three firefighters become trapped, resulting in a mayday, bailout and resulting LODD of a 16 year fire service veteran. City of Yonkers (NY) Firefighter Patrick Joyce  died during the operations at a 3-Alarm fire in a three story residential occupancy while conducting search and rescue operations for reported trapped civilians. Incident overviews; HERE and HERE .

The other structure fire in a residential occupancy in Syracuse, NY, results in a fire fighter mayday and successful RIT extraction that is captured on video.  Two structure fires with common elements, each with projected predictable outcomes based upon past fire department operational experiences at similar structures, occupancies and fire conditions and reports; however with two different outcomes.

The program information from The IAFF Fire Ground Survival Program (FGS)which forms a major component of thsis year’s Safety Weeks activities with the focus on comprehensive survival-skills and mayday-prevention programming  incorporating incident-management best practices and survival techniques from leaders in the field, and real case studies from experienced fire fighters, with the FGS program objectives  aimed to educate all fire fighters to be prepared if the unfortunate happens.

  • For links to the IAFF Fire Ground Survival Program, HERE and HERE

Here’s a recap of the Self-Survial Procedure insights from the FGS Chapter 3 Section;

Self-Survival Procedures

FGS Online Program Chapter 3
To improve survivability in a Mayday situation, a fire fighter must know how to alert rescuers to his or her location and perform self-survival techniques. Through the study of fire fighter fatalities, NIOSH has identified specific actions fire fighters can take to help save themselves. Variations of this same NIOSH recommendation have appeared in numerous fire fighter fatality reports. These recommendations were used to create a self survival procedure that is easy to remember using a mnemonic (GRAB LIVES). Following these steps increases the likelihood of the rescuers finding and assisting the fire fighter to safety.
When a fire captain died when trapped by partial roof collapse in a vacant house fire in Texas, NIOSH recommended in report number F2005-09 that trapped fire fighters should:

  • First, transmit a distress signal while they still have the capability and sufficient air.
  • Next, manually activate their PASS device. To conserve air while waiting to be rescued, try to stay calm and avoid unnecessary physical activity.
  • If not in immediate danger, remain in one place to help rescuers locate them.
  • Survey their surroundings to get their bearings and determine potential escape routes.
  • Stay in radio contact with the IC and other rescuers.
  • Attract attention by maximizing the sound of their PASS device (e.g., by pointing it in an open direction); pointing their flashlight toward the ceiling or moving it around; and using a tool to make tapping noises on the floor or wall. 

The following video clip depicting FDNY Rescue Co. 1 operations at a Mayday, and provides some insightful and subtle commentary that should put some things in proper perspective about the job its hazards and the unexpected that can occur in the blink of an eye.

 

Another exceptional training piece that we are providing again here on CommandSafety.com are the two part video clips provided by TheBravestOnline.com that covers the mayday distress cakk an subsequent RIT extraction of HFD Captain Joel Eric Abbt at a four alarm fire with civilian fatalities in a six story high rise office building on March 28, 2007.

This video along with the information obtained from the FGS  program can provide substantial opportunites for training, discussions and dialog.  Take the time to watch the HFD vdeo and the elapsed time, communications and actions deployed. This mayday event had a successful outcome due to a variety of factors.

The question is how prepared are you, your firefighters, the officers and commanders? Surviving the fire ground requires a  wide variety of skills, knowledge , training and experience.

Training is the foundation from which proficiencies are developed. If your organization has invested in supporting this weeks activities, don’t stop here. There are additional day ahead to take teh momentum gathered from this week and use it to chart a new course of actions and committments for the weeks and months ahead. If you didn’t have the opportunity to engage or involve, its not a missed opportuity- just find the right time and place to have your own safety day of week.

Other Training and Drill Opportunties

Suggested Considerations include the follow, as well as encouraging Departments to identify and integrate local issues, needs and identified gaps or enhancements that can contribute towards operational excellence and safety integration

  • Review and Select a Near Miss Event Report from the National Fire Fighter Near Miss Reporting System or the Report of the Week (ROTW) series related to functional area topics or mayday actions and discuss the event in a small group or company setting to identify similarities or difference from your our organization. Is your company or department susceptible to a similar event? What should be addressed? http://www.firefighternearmiss.com/
  • Review and Select a NIOSH LODD Report from the NIOSH Fire Fighter Fatality Investigation Program related to functional area topics or mayday actions and discuss the event in a small group or company setting to identify similarities or difference from your our organization. Is your company or department susceptible to a similar event? What should be addressed? http://www.cdc.gov/niosh/fire/
  • Take out your Rapid Intervention Equipment and review the purpose and function of each piece of equipment. Identify and discuss alternative uses or tools that can be obtained or used in the event of unavailability, malfunction or additional resource needs. Discuss protocols, procedures, safety awareness and operational hazards, expectations and precautions. Inspection the equipment for operability and integrity.
  • Identify and select a recent departmental or local/regional incident event that was either a near-miss/close-call or transitioned into a mayday event. Discuss and facilitate dialog on lessons learned, gaps, enhancements or operational successes, achievements and positive elements. Identify any factors or elements that were presented in the FGS training series that are applicable to the event, strategies, tactics or operations: can anything be improved or enhanced?
  • Lead a discussion on how to call and initiate a Mayday. Discuss the factors and insights from FGS Program Chapter 3 Self-Survival Procedures and Chapter 4 Self-Survival Skills.
  • Select and lead a discussion on a pertinent incident case study from either the list provided or your own selection and discuss the relevancy of the event in terms of mayday operations, fire ground survival, incident outcome and relationship to your Department or agency. What is the relevancy, similarities or differences? Can this event or circumstances occur in your jurisdiction?  What can be done to prevent a history repeating event (HRE)?
  • Review and discuss Roles and Responsibilities for mayday events and operations. How do they match up with your operating procedures, policies and expectations?
  • Develop and facilitate a table top exercise (TTE) on a mayday event scenario utilizing a building in your first-due or response jurisdiction. Take photographs and integrate into your program. Refer to example of a simple TTE  attached or go to Fire Fighternation.com for an example here; http://www.firefighternation.com/forum/topics/box-2752reported-fire-in-an
  • Visit a residential or commercial construction site (with pre-arrival authorization and approvals) and tour the stage of construction, looking critically at the type of construction and structural systems being implemented, materials used, workmanship and signs of deficient or adverse conditions that may affect operational integrity, safety or collapse and compromise once the building is occupied. Discuss issues such as structural integrity, collapse risk, occupancy risk versus occupancy type considerations, avenues for fire travel, effects on fire load package and rate of heat release and projected fire intensity. How would you fire a fire in the occupancy? What will define the strategy and tactics that would be or should be selected and used?
  • In a controlled setting with or without PPE, Practice calling a mayday with the identified communication attributes defined in the FGS training program. Critique and practice the evolution until the group feels that it is acceptable.

Fire/EMS Safety, Health and Survival Week 2011, Day Six; From Waldbaum’s to Hackensack-Worcester to Charleston; Legacies for Operational Safety

3 comments

Fire Service Tradition and The Brotherhood

For those of you that follow or have attended one of my many seminar and lecture program offerings, one program seems very pertinent in both context and content on this, the Sixth Day of Fire/EMS Safety Week 2011 that resonates around the theme and focus of Surviving the Fire Ground – Fire Fighter, Fire Officer and Command Preparedness.

“From Waldbaum’s to Hackensack-Worcester to Charleston; Legacies for Operational Safety”; in most cases, any discussion of these four landmark incidents in the fire service leads directly to a rich discussion and dialog on a myriad of facets, aspects and issues characteristic of the incidents; the time, the place, the circumstances, the names and faces, the deployment, the operations, the challenges and the tragic outcomes.

The legacies of these iconic events as well as so many others of national prominence and impact; and others with lesser national significance, but having far reaching implications, impacts and power on the regional and local levels continue to shine in the remembrance, honor and memory of those impacted by those events and incidents.

I still find it astonishing during my lecture travels around the country lecturing and presenting these programs on building construction and fireground operations, that when those in attendance were posed with a simple question; “What do the Walbaum’s Fire and Hackensack fire share in common?”, the response at times was less than stellar, or at best difficult to solicit let alone convey the commonalities.

The more seasoned and experienced veterans (translation; older firefighters) when present, were able to convey some information on the subject – Some, with a firm and reflected understanding of the question and its ramifications, others not so much. But yet, the true essence of the basic incident particulars and the lessons learned in most cases failed to be fully conveyed. It’s sad to state but; we are not remembering the past!

History Repeating Events-Integrate into your Training

 

Are the fire service legacies of the past and the lessons learned from those incidents and the sacrifices that were made transcending time? Or are they lost in the immediacy of day to day challenges, issues and operations.

Or are these events, lessons and operations issues dismissed and disregarded as a result of their “time and place” not being relevant to “today’s” operations and modern fire service advancements or lack the relevancy to local organizations, operations, make-up and risks. Is it just a “Big City” issue or is it a failure to comprehend the commonality of the event parameters and distill those lessons learned and operations into the essence that is formulative of all of our organizations and operations?

Surviving the Fire Ground – Fire Fighter, Fire Officer and Command Preparedness, has a multitude of facets, features and functional elements. I spoke of some of these commonalities in a previous post this week on Day Two (HERE).

I’ve spoken on numerous occasions about History Repeating Events (HRE), and the common themes related to fire fighter line-of-duty deaths, close-calls, near-misses, maydays and incident operations that had less than desirable outcomes or performance.

These History Repeating Events and incidents on a wide variation of scale, outcome and operations have common issues, apparent and contributing causes and operational factors that share legacy issues that the fire service at times fails to identify, relate to and implement. In other words, (we) fail a times to learn from the past or we make a deliberate choice to ignore those lessons and the apparent similarities and prevailing fireground indicators due to other internal or external influences, pressures, authority, beliefs, values or viewpoints.

What are we Learning? What are we Applying?

We make choices and we determine our direction, path and destiny. Officers, Commanders, Companies fail to connect with situational factors, parallels and signs that have the full potential to direct the incident towards favorable or disastrous conclusions.  The Job isn’t as fatalistic as we sometimes make it out to be.

The prevailing topical areas being addressed this year during Safety week have focused on the mayday component of an incident operation and have included:

  • Preventing the Mayday: situational awareness, planning, size up, air management, fitness for survival, defensive operations.
  • Being Ready for the Mayday: personal safety equipment, communications, accountability systems.
  • Self-Survival Procedures: avoiding panic, mnemonic learning aid “GRAB LIVES”— actions a fire fighter must take to improve survivability, emergency breathing.
  • Self-Survival Skills: SCBA familiarization, emergency procedures, disentanglement, upper floor escape techniques.
  • Fire Fighter Expectations of Command: command-level mayday training, pre-mayday, mayday and rescue, post-rescue, expanding the incident-command system, communications.

There’s ample opportunity this week or in the weeks ahead to do some insightful research or cull some information on the four legacy events we discussed earlier;

  • FDNY Waldbaum’s Fire (1978) HERE and HERE
  • Hackensack (NJ) Auto Dealership Fire (1988) HERE and HERE
  • Worcester (MA) Cold Storage Fire (1999) HERE and HERE
  • Charleston (SC) Sofa Super Store (2007) HERE and HERE

These have tremendous Legacies for Operational Safety, lessons and a wealth of applications for Safety Week and for training, dialog, discussions, tabletops, skillsets and drill activities throughout the entire year.

Integrate the lessons from these as well as other legacies and HRE into your Surviving the Fire Ground – Fire Fighter, Fire Officer and Command Preparedness; training and deliveries. The reality is, we, the present generation of veteran firefighters and officers have the profound obligation and responsibility to recognize the importance of passing along the lessons of the past as well as integrating and playing forward the lessons of our life’s journey throughout our fire service careers; the events of our day and the profound tough lessons and sacrifices learned the hard way. Understand and embrace the shared responsibilities, accountability and requirements that contribute towards Surviving the Fire Ground.

We sometimes need a receptive, sympathetic and compassionate audience that is willing to listen, hear and comprehend the messages conveyed. There needs to be a high degree of empathy related to these past History Repeating Events, the legacies of national, regional and local level prominence. For each event, each and every line of duty death, close-call, near-miss and mayday event has a message and a Legacy of Operational Safety.

Make the time to research, learn and understand the factors of these events, the lessons and opportunities that are borne from each and how they relate to the theme, message and initiatives that make up Fire/EMS Safety, Health and Survival Week and beyond.

Fire/EMS Safety, Health and Survival Week: Day Four -The New Fire Ground

Fire/EMS Safety, Health and Survival Week: Day Four -The New Fire Ground    

 

There is an immediate need for today’s emerging and operating command and company officers to increase their foundation of knowledge and insights related to the modern building occupancy, building construction and fire protection engineering and to adjust and modify traditional and conventional strategic operating profiles in order to safeguard companies, personnel and team compositions.

Strategies and tactics must be based on occupancy risk, not occupancy type, and must have the combined adequacy of sufficient staffing, fire flow and tactical patience orchestrated in a manner that identifies with the fire and building profiling, predictability of the occupancy profile and accounts for presumptive fire behavior. It is not your old method of size-up and operational deployment.

The dramatic changes in buildings and occupancies over the past ten years have resulted inadequate fire suppression methodologies based upon conventional practices that do not align with the manner in which we used to discern with a measured degree of predictability how buildings would perform, react and fail under most fire conditions. These past presumptions, which many of us debated with our esteemed colleagues, are being validated through empirical data resulting from the cutting edge research and testing being conducted today by UL and NIST.

Predicting Fire Behavior and Building Stability

We predicate certain expectations that fire will travel in a defined (predictable) manner that fire will hold within a room and compartment for a predictable given duration of time; that the fire load and related fire flows required will be appropriate for an expected size and severity of fire encountered within a given building, occupancy, structural system and given an appropriately trained and skilled staff to perform the requisite evolutions, we can safely and effectively mitigate a structural fire situation in any  given building type and occupancy.

  • Past operational experiences, both favorable and negative; gave us experiences that define and determine how the fireground is assessed, react and how we expect similar structures and occupancies to perform at a given alarm in the future; this formed the basis for the naturalistic decision-making process.

Implementing fundamentals of firefighting operations built upon nine decades of time-tested and experience-proven strategies and tactics continues to be the model of suppression operations. These same fundamental strategies continue to drive methodologies and curriculums in our current training programs and academies of instructions.

Are you aware of the defining changes in structural systems and support, the degree of compartmentation,

  • the characteristics of materials and the magnitude of the fire-loading package in today’s buildings and occupancies?
  • When was the last time you were out in the street with the companies, or spent some time doing a walk-through of construction or renovations site?
  • Have you asked you commanding officers, division or battalion chief or your company officers for insights into what operational demands and risks are being imposed upon them while operating in the street and within the buildings, occupancies and structures that comprise your jurisdiction?

The structural anatomy, predictability of building performance under fire conditions, structural integrity and the extreme fire behavior; accelerated growth rate and intensively levels typically encountered in buildings of modern construction during initial and sustained fire suppression have given new meaning to the term combat fire engagement.

It’s no longer just brute force and sheer physical determination that define structural fire suppression operations, although any seasoned command and company officer knows that at times. It’s what gets the job done under the most arduous and demanding of circumstances.

However, from a methodical and disciplined perspective; aggressive firefighting must be redefined and aligned to the built environment and associated with goal-oriented tactical operations that are defined by risk assessed and analyzed strategic processes that are executed under battle plans that promote the best in safety practices and survivability within known hostile structural fire environments.

The demands and requirements of modern firefighting will continue to require the placement of personnel within situations and buildings that carry risk, uncertainty and inherent danger. As a result, risk management must become fluid and integrated with intelligent tactical deployments and operations recognizing the risk problematically and not fatalistically, resulting in safety conscious strategies and tactics.

Today’s incident commanders need to think about the Predicative Strategic Process, refined Tactical Deployment Models integrating intelligent Structural Anatomy and Predictive Occupancy Profiling, while implementing Tactical Patience.

Think about the following;

  • Read, comprehend and implement the new IAFC The Rules of Engagement for Firefighter Survival and The Incident Commanders Rules of Engagement for Firefighter Safety
  • Take a tour of your response area, district, community or city.
  • Take a good look around and begin to recognize the apparent or subtle changes that are affecting your incident operations; Take note and think about what needs to be adjusted, modified or changed in your operations.
  • Read up on the latest research and technical literature on wind driven fires, extreme fire behavior, structural ability of engineered lumber systems, fire loading and suppression theory
  • Take the time to personally read a series of the latest NIOSH Fire Fighter Fatality Investigation and Prevention Program LODD reports and relate them to your organizations operations and jurisdictional risks.
  • Start thinking in terms of Occupancy Risks versus Occupancy Type and align your operations and deployments to match those risks
  • Increase your situational awareness of today’s fireground and refine your strategic and tactical modeling
  • Implement both Strategic and Tactical Patience; Slow down and allow the building to react and stabilize, for fire behavior to stop behaving badly and for your companies to increase survivability ratios while meeting the demands of  conducting fire service operations
  • Think about Adaptive Fire Ground Management and Command Resiliency
  • Reprogram your assumptions and presumptions and options on building construction and firefighting operations; the buildings have changed, our firefighting has not; what are you going to do about that gap?

If you don’t fully understand how a building truly performs or reacts under fire conditions and the variables that can influence its stability and degradation, movement of fire and products of combustion and the resource requirements for fire suppression in terms of staffing, apparatus and required fire flows, then you will be functioning and operating in a reactionary manner that is no longer acceptable within many of our modern building types, occupancies and structures.

This places higher risk to your personnel and lessens the likelihood for effective, efficient and safe operations. You’re just not doing your job effectively and you’re at risk. These risks can equate into insurmountable operational challenges and could lead to adverse incident outcomes. Someone could get hurt, someone could die, it’s that simple; it’s that obvious.

Without understanding the building-occupancy relationships and integrating; construction, occupancies, fire dynamics and fire behavior, risk, analysis, the art and science of firefighting, safety conscious work environment concepts and effective and well-informed incident command management, company-level supervision and task-level competencies … You are derelict and negligent and “not “everyone may be going home”.

It’s all about understanding the building-occupancy relationships and the art and science of firefighting, equating to Building Knowledge = Firefighter Safety.

The New Fire Ground

NIST Wind Driven Fire Study

  • Smoke and heat spreading through the corridors and the stairs of a building during a fire can limit building occupants’ ability to escape and can limit fire fighters’ ability to rescue them.  Changes in the building’s ventilation or presence of an external wind can increase the energy release of the fire.  This can also increase the spread of fire gases through the building.  In some cases, such as the Cook County Administration Building fire in October 2003, the fire gas flow, into the corridors and the stairway prevented fire fighters from suppressing the fire from inside the structure.  This fire resulted in 6 building occupant fatalities and fire fighter injuries in the stairway.  The Fire Department of New York City has experienced many wind driven fire incidents which have resulted in fire fighter fatalities and injuries, as have a number of other incidents nationally that have resulted in increased research into this operational and tactical challenge.
  • What tactics or tools are appropriate for use with a wind driven fire and how should the tactics or tools be implemented?  Positive Pressure Ventilation (PPV) is being used by fire departments on smaller structures, such as single family homes, to control the fire flow by introducing pressure from the front door and venting the house through a strategic exit opening.  If done correctly, this tactic can remove significant amounts of heat and smoke from the structure, thus improving the fire fighters’ working environment and improving the chances of survival for the building occupants.  NIST has completed several studies which have a two fold impact: 1) providing guidance on the safe use of PPV and 2) characterizing and validating the modeling of PPV with a computational fluid dynamics (CFD) computer model, so that the model can be used as a training tool for the fire service.
  • This project extends previous work for ventilation under wind driven conditions.  There are many questions regarding wind driven fires.  For example can these PPV fans be used successfully under wind driven fire conditions in large structures?  Large structures, such as high rise buildings, provide additional challenges to fire fighter and building occupant safety: increased travel distance (exposure time), more complicated egress path, and potentially larger fires.  In 2002 there were 7,300 reported fires in high rise structures.
  • Other tactics incorporating devices, such as wind control devices (WCD) to control the ventilation conditions or the use of a “high rise” nozzle from the floor below the fire floor have been tried by the fire service under “real fire” conditions with varying levels of success.
  • A comprehensive free DVD set from the NIST includes a presentation video that explains PPV, examines the results of NIST’s PPV research, and closes with a focus on the use of PPV tactics in high-rise buildings.  All of the NIST PPV reports referenced in the presentation are included on Disc 1 of the set.  All of the videos from the high-rise fire experiments are also provided with a user-friendly, graphic menu that can be used on a PC or a DVD player.  NIST, with support from USFA, DHS, and fire departments across the country, has taken engineering principles and applied them to fire service PPV tactics in order to improve fire fighter safety

NIST Fire Fighting Tactics Under Wind Driven Conditions: Laboratory Experiments

  • A series of experiments was conducted in our Large Fire Laboratory to examine the impact of wind control curtains and externally applied hose streams on a wind driven fire.  The results from these experiments will allow us to better understand the fire dynamics within a structure and provide guidance as to the important measurements needed in the future experiments in a high-rise on Governor’s Island in New York City.

NIST Firefighter Safety and Deployment Study; Report on Residential Fireground Field Experiments

  • The NIST Firefighter Safety and Deployment Study; Titled- Report on Residential Fireground Field Experiments was recently released to the public providing . A copy of the report is attached.
  • Report Abstract:
  • Service expectations placed on the fire service, including Emergency Medical Services (EMS), response to natural disasters, hazardous materials incidents, and acts of terrorism, have steadily increased. However, local decision-makers are challenged to balance these community service expectations with finite resources without a solid technical foundation for evaluating the impact of staffing and deployment decisions on the safety of the public and firefighters. For the first time, this study investigates the effect of varying crew size, first apparatus arrival time, and response time on firefighter safety, overall task completion, and interior residential tenability using realistic residential fires.
  • This study is also unique because of the array of stakeholders and the caliber of technical experts involved. Additionally, the structure used in the field experiments included customized instrumentation; all related industry standards were followed; and robust research methods were used. The results and conclusions will directly inform the NPFA 1710 Technical Committee, who is responsible for developing consensus industry deployment standards.
  • This report presents the results of more than 60 laboratory and residential fireground experiments designed to quantify the effects of various fire department deployment configurations on the most common type of fire—a low hazard residential structure fire. For the fireground experiments, a 2,000 sq ft (186 m2), two-story residential structure was designed and built at the Montgomery County Public Safety Training Academy in Rockville, MD. Fire crews from Montgomery County, MD and Fairfax County.
  • Report results quantify the effectiveness of crew size, first-due engine arrival time, and apparatus arrival stagger on the duration and time to completion of the key 22 fireground tasks and the effect on occupant and firefighter safety.
  • The report is also available for download at the NIST, HERE
  • Synopsis HERE

USFA/NIST Trends in Firefighter Fatalities Due to Structural Collapse, 1979-2002

  • Between the years 1979 and 2002 there were over 180 firefighter fatalities due to structural collapse, not including those firefighters lost in 2001 in the collapse of the World Trade Center Towers. Structural collapse is an insidious problem within the fire fighting community. It often occurs without warning and can easily cause multiple fatalities.
  • As part of a larger research program to help reduce firefighter injuries and fatalities the U.S. Fire Administration (USFA) funded the National Institute of Standards and Technology (NIST) to examine records and determine if there were any trends and/or patterns that could be detected in firefighter fatalities due to structural collapse. If so, these trends could be brought immediately to the attention of training officers and incident commanders and investigated further to determine probable causes.

Fire Behavior 101; Taking it to the Streets

  

  

Impact of Ventilation on Fire Behavior in Legacy and Contemporary Residential Construction

For many of you that have been following my writings and perspectives on building construction, firefighting, command risk management and operational excellence for firefighter safety have long recognized that I have been promoting and advocating the fact the fireground is changing, our strategies and tactics demand change and does the demand for increased knowledge within the areas of building construction, fire dynamics, while integrating the art and science of firefighting. The most recent release of the testing report from Underwriters Laboratories; Impact of Ventilation on Fire Behavior in Legacy and Contemporary Residential Construction and the accompanying empirical data further validates assumptions and premises that many of us shared based upon field observations and first hand incident operations related to the dramatic changes being witnessed as a result of operational challenges in a wide variety of occupancies and building types.

This material is a must read for all emerging and practicing company and command officers ( for starters) to being grasping the magnitude and extent of quantifiable data that supports the premise that combat fire engagement and suppression operations and the rules of engagement are going to change and that change is fast approaching.

Here’s the executive summary of the report and findings from UL. For an download of the entire UL Report, go HERE.

The results of these experiments provide knowledge for the fire service for them to examine their thought processes, standard operating procedures and training content. Several tactical considerations were developed utilizing the data from the experiments to provide specific examples of changes that can be adopted based on a departments current strategies and tactics.

Under the United States Department of Homeland Security (DHS) Assistance to Firefighter Grant Program, Underwriters Laboratories examined fire service ventilation practices as well as the impact of changes in modern house geometries.

There has been a steady change in the residential fire environment over the past several decades. These changes include larger homes, more open floor plans and volumes and increased synthetic fuel loads. This series of experiments examine this change in fire behavior and the impact on firefighter ventilation tactics.

This fire research project developed the empirical data that is needed to quantify the fire behavior associated with these scenarios and result in immediately developing the necessary firefighting ventilation practices to reduce firefighter death and injury.

  • Two houses were constructed in the large fire facility of Underwriters Laboratories in Northbrook, IL.
  • The first of two houses constructed was a one-story, 1200 ft2, 3 bedroom, 1 bathroom house with 8 total rooms.
  • The second house was a two-story 3200 ft2, 4 bedroom, and 2.5 bathroom house with 12 total rooms.
  • The second house featured a modern open floor plan, two story great room and open foyer.

 Fifteen experiments were conducted varying the ventilation locations and the number of ventilation openings. Ventilation scenarios included ventilating the front door only, opening the front door and a window near and remote from the seat of the fire, opening a window only and ventilating a higher opening in the two-story house.

One scenario in each house was conducted in triplicate to examine repeatability. The results of these experiments provide knowledge for the fire service for them to examine their thought processes, standard operating procedures and training content. Several tactical considerations were developed utilizing the data from the experiments to provide specific examples of changes that can be adopted based on a departments current strategies and tactics.

Room Flashover from Sofa Fire

 

The tactical considerations addressed include:

  • Stages of fire development: The stages of fire development change when a fire becomes ventilation limited.
    • It is common with today’s fire environment to have a decay period prior to flashover which emphasizes the importance of ventilation
  • Forcing the front door is ventilation: Forcing entry has to be thought of as ventilation as well.
    •  
    • While forcing entry is necessary to fight the fire it must also trigger the thought that air is being fed to the fire and the clock is ticking before either the fire gets extinguished or it grows until an untenable condition exists jeopardizing the safety of everyone in the structure.
  • No smoke showing: A common event during the experiments was that once the fire became ventilation limited the smoke being forced out of the gaps of the houses greatly diminished or stopped all together.
    • No some showing during size-up should increase awareness of the potential conditions inside.
  • Coordination: If you add air to the fire and don’t apply water in the appropriate time frame the fire gets larger and safety decreases.
    • Examining the times to untenability gives the best case scenario of how coordinated the attack needs to be.
    • Taking the average time for every experiment from the time of ventilation to the time of the onset of firefighter untenability conditions yields 100 seconds for the one-story house and 200 seconds for the two-story house
    • In many of the experiments from the onset of firefighter untenability until flashover was less than 10 seconds.
    • These times should be treated as being very conservative. If a vent location already exists because the homeowner left a window or door open then the fire is going to respond faster to additional ventilation opening because the temperatures in the house are going to be higher.
    • Coordination of fire attack crew is essential for a positive outcome in today’s fire environment.
  • Smoke tunneling and rapid air movement through the front door: Once the front door is opened attention should be given to the flow through the front door.
    • A rapid in rush of air or a tunneling effect could indicate a ventilation limited fire.
  • Vent Enter Search (VES): During a VES operation, primary importance should be given to closing the door to the room.
    • This eliminates the impact of the open vent and increases tenability for potential occupants and firefighters while the smoke ventilates from the now isolated room.
  • Flow paths: Every new ventilation opening provides a new flow path to the fire and vice versa.
    • This could create very dangerous conditions when there is a ventilation limited fire.
  • Can you vent enough?: In the experiments where multiple ventilation locations were made it was not possible to create fuel limited fires.
    • The fire responded to all the additional air provided.
    • That means that even with a ventilation location open the fire is still ventilation limited and will respond just as fast or faster to any additional air.
    • It is more likely that the fire will respond faster because the already open ventilation location is allowing the fire to maintain a higher temperature than if everything was closed. In these cases rapid fire progression if highly probable and coordination of fire attack with ventilation is paramount.
  • Impact of shut door on occupant tenability and firefighter tenability: Conditions in every experiment for the closed bedroom remained tenable for temperature and oxygen concentration thresholds.
    • This means that the act of closing a door between the occupant and the fire or a firefighter and the fire can increase the chance of survivability.
    • During firefighter operations if a firefighter is searching ahead of a hoseline or becomes separated from his crew and conditions deteriorate then a good choice of actions would be to get in a room with a closed door until the fire is knocked down or escape out of the room’s window with more time provided by the closed door
  • Potential impact of open vent already on flashover time: All of these experiments were designed to examine the first ventilation actions by an arriving crew when there are no ventilation openings.
    • It is possible that the fire will fail a window prior to fire department arrival or that a door or window was left open by the occupant while exiting.
    • It is important to understand that an already open ventilation location is providing air to the fire, allowing it to sustain or grow.
  • Pushing fire: There were no temperature spikes in any of the rooms, especially the rooms adjacent to the fire room when water was applied from the outside. It appears that in most cases the fire was slowed down by the water application and that external water application had no negative impacts to occupant survivability.
    • While the fog stream “pushed” steam along the flow path there was no fire “pushed”.
  • No damage to surrounding rooms: Just as the fire triangle depicts, fire needs oxygen to burn.
    • A condition that existed in every experiment was that the fire (living room or family room) grew until oxygen was reduced below levels to sustain it.
    • This means that it decreased the oxygen in the entire house by lowering the oxygen in surrounding rooms and the more remote bedrooms until combustion was not possible.
    • In most cases surrounding rooms such as the dining room and kitchen had no fire in them even when the fire room was fully involved in flames and was ventilating out of the structure.

Online Training Program

Fire/EMS Safety, Health and Survival Week: Day Three-The New Rules of Engagement

Fire/EMS Safety, Health and Survival Week: Day Three-The New Rules of Engagement

 With so many changes (budget cuts, staffing reductions, reduced training, etc.) in so many fire departments, it is critical for fire fighters to focus on their own survival on the fire ground. There is no other call more challenging to fire ground operations than a Mayday call the unthinkable moment when a fire fighter’s personal safety is in imminent danger. Fire fighter fatality data compiled by the United States Fire Administration have shown that fire fighters becoming trapped and disoriented represent the largest portion of structural fire ground fatalities. The incidents in which fire fighters have lost their lives, or lived to tell about it, have a consistent theme inadequate situational awareness put them at risk.

New Rules of Engagement

 Fire fighters don’t plan to be lost, disoriented, injured or trapped during a structure fire or emergency incident. But fires are unpredictable and volatile, and they will not always go according to plan. What a fire fighter knows about a fire before entering a blazing building may radically change within minutes once inside the structure. Smoke, low visibility, lack of oxygen, structural instability and an unpredictable fire ground can cause even the most seasoned fire fighter to be overwhelmed in an instant.

It's Not a Matter of IF, It's a Matter of When

It’s not a matter of IF the MAYDAY happens, it’s WHEN! Thius the reason for the 2011 Fire/EMS Safety, Health and Survival Week focus on Surviving the Fire Ground Fire Fighter, Fire Officer & Command Preparedness

Theme: Surviving the Fire Ground Fire Fighter, Fire Officer & Command Preparedness

  • IAFC Safety Week Resources: Firefighter Survival, HERE
  • National Fire Fighter Near Miss Reporting System Resources, HERE

With that being said, there must be a means and a method to better defined and more accurately

  • Without understanding the building-occupancy relationships and integrating; construction, occupancies, fire dynamics and fire behavior, risk, analysis, the art and science of firefighting, safety conscious work environment concepts and effective and well-informed incident command management, company level supervision and task level competencies…You are derelict and negligent and “not “everyone may be going home”.
  • Our current generation of buildings, construction and occupancies are not as predictable as past conventional construction; risk assessment, strategies and tactics must change to address these new rules of structural fire engagement.
  • There is a need to gain the building construction knowledge and insights and to change and adjust operating profiles in order to safe guard companies, personnel and team compositions. It’s all about understanding the building-occupancy relationships and the art and science of firefighting, Building Knowledge = Firefighter Safety (Bk=F2S)
  • Refer to: Fire/EMS Safety, Health and Survival Week: Day Two- Building Knowledge = Fire Fighter Safety 
  • When we look at various buildings and occupancies, past operational experiences; those that were successful, and those that were not, give us experiences that define and determine how we access, react and expect similar structures and occupancies to perform at a given alarm in the future.
  • Naturalistic (or recognition-primed) decision-making forms much of this basis. We predicate certain expectations that fire will travel in a defined (predictable) manner that fire will hold within a room and compartment for a predictable given duration of time; that the fire load and related fire flows required will be appropriate for an expected size and severity of fire encountered within a given building, occupancy, structural system; in addition to having an appropriately trained and skilled staff to perform the requisite evolutions.
  • Executing tactical plans based upon faulted or inaccurate strategic insights and indicators has proven to be a common apparent cause in numerous case studies, after action reports and LODD reports.
  • Our years of predictable fireground experience have ultimately embedded and clouded our ability to predict, assess, plan and implement incident action plans and ultimately deploy our companies-based upon the predictable performance expected of modern construction and especially those with engineered structural systems.
  • If you don’t fully understand how a building truly performs or reacts under fire conditions and the variables that can influence its stability and degradation, movement of fire and products of combustion and the resource requirements for fire suppression in terms of staffing, apparatus and required fire flows, then you will be functioning and operating in a reactionary manner, that is no longer acceptable within many of our modern building types, occupancies and structures.
  • This places higher risk to your personnel and lessens the likelihood for effective, efficient and safe operations.
  • You’re just not doing your job effectively and you’re at RISK. These risks can equate into insurmountable operational challenges and could lead to adverse incident outcomes. Someone could get hurt, someone could die, it’s that simple; it’s that obvious

 

Original IAFC 2001 ROE

 

  • Combat Fire Suppression and Engagement has been dramatically influenced by numerous challenges in terms of effectiveness, methodologies, risk and operational capabilities….yet we implement strategic and tactical models and protocol predicated on past performance of building structures and occupancies and fire fighting successes….
  •  It’s no longer just brute force and sheer physical determination that define structural fire suppression operations
  • We used to discern with a measured degree of predictability, how buildings would perform, react and fail under most fire conditions. Implementing fundamentals of firefighting and engine company operations built upon eight decades of time tested and experience proven strategies and tactics continues to be the model of suppression operations.
  • These same fundamental strategies continue to drive methodologies and curriculums in our current training programs and academies of instructions.
  • 2009 was a significant and decisive year for the fire service in a number of ways….
  • Controversy, debate, argument; enlightenment, knowledge, insights, awareness, comprehension, understanding….
  • Which leads me to call this the emerging tactical renaissance….

 

The International Association of Fire Chiefs (IAFC) is committed to reducing firefighter fatalities and injuries. As part of that effort the nearly 1,000 member Safety, Health and Survival Section of the IAFC has developed the NEW  “Rules of Engagement of Structural Firefighting” to provide guidance to individual firefighters, and incident commanders, regarding risk and safety issues when operating on the fireground.

The intent was to provide a set of “model procedures” for Rules of Engagement for Structural Firefighting to be made available by the IAFC to fire departments as a guide for their own standard operating procedure development.

In August, 2008, following a year of discussion, the Section moved to develop a set of “Rules of Engagement for Structure Firefighting”.

A project team was created consisting of Section members and representatives of other several other interested fire service organizations.

These included the;

  • Fire Department Safety Officer Association (FDSOA),
  • the National Fallen Firefighter Foundation (NFFF),
  • the National Volunteer Fire Council (NVFC), the
  • National Institute of Occupational Safety and Health (NIOSH) and other organizations.
  • All draft material has also been shared with representatives of the International Association of Fire Fighters (IAFF) who developed a joint IAFF/IAFC Fire Ground Survival Project”.

 Three Section members also participated in the IAFF project.

The direction provided the project team by the Section leadership was to develop rules of engagement with the following conceptual points;

  • Rules should be a short, specific set of bullets
  • Rules should be easily taught and remembered
  • Rules should define critical risk issues
  • Rules should define “go” or “nogo” situations
  • A companion lesson plan/explanation section should be provided

Early in development the Rules of Engagement, it was recognized that two separate rules were needed –one set for the firefighter, and another set for the incident commander.

Thus, the two sets of Rules of Engagement were conceived and developed.

Each set has several commonly shared bullets and objectives, but the explanations are described somewhat differently based on the level of responsibility (firefighter vs. incident commander).

The 2010 Rules of Engagement reflects nearly two years of public comment and feedback from several presentations at fire service conferences, including the National Fallen Fire Fighters Safety Summit held at the National Fire Academy this past March 2010.

The “Rules” was formally adopted by the IAFC Health, Safety and Survival Section at the Fire Rescue International Conference that was held in Chicago this past August 2010

The project team was lead by Chief Gary Morris,

 The Need for Rules of Engagement

  • Firefighter safety must always be a priority for every fire chief and every member. Over the past three decades, the fire service has applied new technology, better protective clothing and equipment, implemented modern standard operating procedures, and improved training.
  • According to National Fire Protection Association (NFPA) data during this same period the fire service has experienced a 58 percent reduction in firefighter line of duty deaths. But, the country has also seen a paralleling 54 percent drop in the number of structural fires over the same period – thus, reducing firefighter exposure to risk.
  • With a continued annual average of more than 100 firefighter fatalities, the question remains; have we really made a difference with all these technology improvements? Or, is there more that we can do to improve the safety culture of the American fire service?
  • The U.S. Firefighter Disorientation Study, conducted by Captain Willie Mora, San Antonio, Texas, Fire Department, conducted a review of 444 firefighter fireground deaths occurring over a recent 16 year period (1990-2006).
    • The project broke out traumatic firefighter fatalities occurring in “open structures” and “enclosed structures”. Open structures was defined as smaller structures with an adequate number of windows and doors (within a short distance) to allow for prompt ventilation and emergency evacuation.
    • Enclosed structures were defined as large buildings with inadequate windows or doors to allow prompt ventilation and emergency evacuation. Research determined that 23 percent occurred when a fast and aggressive interior attack was made on an “opened structure”. When fast, aggressive interior attacks occurred in “enclosed structures” the fatality rate rose to 77 percent. Many occurred in “marginal” or rapidly changing conditions in which the firefighter should not have been in the building.
  • The fireground creates a significant risk to firefighters and it is the responsibility of the incident commander and command organization officers to minimize firefighter exposure to unsafe conditions and stop unsafe practices.
  • The fire service has always been a para-military organization when it comes to fireground operations. In most cases, the Incident Commander makes a decision, sends the order down to through supervisors to the company officer and crew.
  • Fire crews generally view these orders as top down direction. There is often little two‐way discussion about options.
  • Where this culture exists, crews have been trained to accept the order and do it – generally without question.
  • While these orders may be viewed as valid when issued they may involve inadequate risk assessment.
  • There has been little national development of basic “rules” that the incident command should use in defining risk assessment process and what is too high risk that may result in a “no-go” decision.
  • Furthermore, for the individual firefighter who is exposed to the greatest risk, we have not defined “rules” for them to follow in assessing their individual risk and when and how to say “no” to unsafe conditions or practices. The “Rules of Engagement” changes that.
  • The “Rules of Engagement” have been developed to assist both the incident command (as well as command team officers) in risk assessment and “Go” – “No-Go” decisions. Applying the rules will make the fireground safer for all and reduce injuries and fatalities.

 

The development of the rules integrated several nationally recognized programs and principles. They included risk assessment principles from NFPA Standards 1500 and 1561.

Also included where concepts and principles from Crew Resource Management (available from iafc.org) and data and lessons from the National Near-Miss Reporting System (firefighternearmiss.com).

The development process also included review of lessons learned from numerous firefighter fatality investigations conducted by the National Institute of Occupational Safety and Health (NIOSH) Fire Fighter Fatality Investigation and Prevention Program.

It’s incumbent that the fire chief and the Departments management team insure the safety of all firefighters working at structural fires.

  • All command organization officers are responsible for their own safety and the safety of all personnel working with them.
  • All officers and members are responsible are responsible for continually identifying and reporting unsafe conditions or practices.
  • The Rules of Engagement allows both the firefighter and the incident commander to apply and process these principles.
  • One principle applied in the Rules of Engagement is firefighters and the company officers are the members at most risk for injury or death.
  • The Rules integrate the firefighter into the risk assessment decision making process.
  • These members should be the ultimate decision maker as to whether it’s safe to proceed with assigned objectives.
  • The “Rules” allow a process for that decision to be made while still maintain command unity and discipline.

 

Operational Excellence and the ROE

 

The NEW Rules of Engagement

It is well known that firefighting is hazardous with varying levels of risk to the firefighter.

However, firefighting is not a military campaign where lives are lost to establish a beach head.

Taking It To The Streets: My Closing Commentary and The Rules of Combat Fire Suppression  

The essence of fire service suppression operations is predicated upon the deployment and application of water as an extinguishing agent, in sufficient quantities, location and duration to extinguish a fire within an enclosed structural compartment. The universal engine company correlation of: “putting the wet stuff on the red stuff” is fundamental to structural fire suppression operations but is ambiguous at best in the context of today’s modern building construction, occupancies, structural systems and building features. 

We used to discern with a measured degree of predictability, how buildings would perform, react and fail under most fire conditions. Implementing fundamentals of firefighting and engine company operations built upon eight decades of time tested and experience proven strategies and tactics continues to be the model of suppression operations. These same fundamental strategies continue to drive methodologies and curriculums in our current training programs and academies of instructions.

The lack of appreciation and the understanding of correlating principles involving fire behavior, fuel and rate of heat release and the growth stages of compartment fires within a structural occupancy are the defining paths from which the fire service must reexamine engine company operations in order to identify with the predictability of occupancy performance during fire suppression operations thus increasing suppression effectiveness and firefighter safety.

Our buildings have changed; the structural systems of support, the degree of compartmentation, the characteristics of materials and the magnitude of fire loading. The structural anatomy, predictability of building performance under fire conditions, structural integrity and the extreme fire behavior; accelerated growth rate and intensively levels typically encountered in buildings of modern construction during initial and sustained fire suppression have given new meaning to the term combat fire engagement.

The rules for combat structural fire suppression have changed, but we have yet to write the rule book from which the new games plans must be derived…..

However, we now have a new set of Rules for Engagement….

  • The Incident Commanders Rules of Engagement for Firefighter Safety
  • Rules of Engagement for Firefighter Survival
  • Tactical Renaissance ……….Tactical Patience

…….integrate cutting edge research and emerging concepts on Tactical Patience, Tactical Entertainment, Command Compression, Structural Anatomy of Buildings, Five Star Command Model, Predicative Strategic Process, refined Tactical Deployment Models integrating intelligent Structural Anatomy and Predictive Occupancy Profiling and Integrating the RULES OF ENGAGEMENT for Structural Firefighting much more.  

It’s really all about Fighting Fire with More Knowledge and smartly

Other Considerations in Program Planning for Safety Week; Other considerations to support the theme, objectives and initiatives of Safety Week include wide latitude of activities and interactive actions that can achieve the goals for increasing awareness and providing dialog, interaction, training while encouraging discussion and interchange.

These functional area topics can be integrated into planned program development to support the FGS training presentations, delivery and support a comprehensive strategy for integrated Fire Ground Survival training, awareness and insights. These functional areas are supported with references and links to support program develop and deliveries.

Suggested Functional Areas for Alignment with the Theme and Focus during Safety Week;

  • 16 Fire Fighter Life Safety Initiatives

  • Rule of Engagement

  • Fire Fighter Near-Miss Learning‘s

  • Procedures, Policies and Guidelines

  • Pre-Fire Planning

  • Building Construction

  • Structural Systems

  • Occupancy Risk Profiling

  • Go to the Planning Resource Guide for Direct Resources, templates and suggested planning and instructional aids. HERE

Suggested considerations include the following, as well as encouraging fire/EMS departments to identify and integrate local issues, needs and identified gaps or enhancements that can contribute towards operational excellence and safety integration.

  • Review and select a Near Miss Event Report from the National Fire Fighter Near-Miss Reporting System or the Report of the Week (ROTW) series related to functional area topics or mayday actions and discuss the event in a small group or company setting to identify similarities or difference from your our organization. Is your company or department susceptible to a similar event? What should be addressed? http://www.firefighternearmiss.com/
  • Review and select a NIOSH LODD Report from the NIOSH Fire Fighter Fatality Investigation Program related to functional area topics or mayday actions and discuss the event in a small group or company setting to identify similarities or difference from your our organization. Is your company or department susceptible to a similar event? What should be addressed? http://www.cdc.gov/niosh/fire/
  • Take out your Rapid Intervention Equipment and review the purpose and function of each piece of equipment. Identify and discuss alternative uses or tools that can be obtained or used in the event of unavailability, malfunction or additional resource needs. Discuss protocols, procedures, safety awareness and operational hazards, expectations and precautions. Inspection the equipment for operability and integrity.
  • Identify and select a recent departmental or local/regional incident event that was either a near-miss/close-call or transitioned into a mayday event. Discuss and facilitate dialog on lessons learned, gaps, enhancements or operational successes, achievements and positive elements. Identify any factors or elements that were presented in the FGS training series that are applicable to the event, strategies, tactics or operations: can anything be improved or enhanced?
  • Lead a discussion on how to call and initiate a Mayday. Discuss the factors and insights from FGS Program Chapter 3 Self-Survival Procedures and Chapter 4 Self-Survival Skills.
  • Select and lead a discussion on a pertinent incident case study from either the list provided or your own selection and discuss the relevancy of the event in terms of mayday operations, fire ground survival, incident outcome and relationship to your Department or agency. What is the relevancy, similarities or differences? Can this event or circumstances occur in your jurisdiction? What can be done to prevent a history repeating event (HRE)?
  • Review and discuss Roles and Responsibilities for mayday events and operations. How do they match up with your operating procedures, policies and expectations?
  • Develop and facilitate a table top exercise (TTE) on a mayday event scenario utilizing a building in your first-due or response jurisdiction. Take photographs and integrate into your program. Refer to example of a simple TTE attached or go to Fire Fighternation.com for an example here; http://www.firefighternation.com/forum/topics/box-2752reported-fire-in-an
  • Visit a residential or commercial construction site (with pre-arrival authorization and approvals) and tour the stage of construction, looking critically at the type of construction and structural systems being implemented, materials used, workmanship and signs of deficient or adverse conditions that may affect operational integrity, safety or collapse and compromise once the building is occupied.
    • Discuss issues such as structural integrity, collapse risk, occupancy risk versus occupancy type considerations, avenues for fire travel, effects on fire load package and rate of heat release and projected fire intensity.
    • How would you fire a fire in the occupancy? What will define the strategy and tactics that would be or should be selected and used?
  • In a controlled setting with or without PPE, Practice calling a mayday with the identified communication attributes defined in the FGS training program. Critique and practice the evolution until the group feels that it is acceptable.

Understand your Response District

 

“Building Knowledge = Firefighter Safety”, Know Your District and its Risk

Protect Yourself: Your Safety, Health and Survival Are Your Responsibility.

 Within the focus area of Survival and the elements of Structural Size-Up and Situational Awareness, some suggeted key functional components could include the following;

  • Keep apprised of different types of building materials and construction used in your community.
  • The operative question today is this: “What do you “really” know about the buildings in your district?”
  • As you drive about your response district today, coming back from an alarm, heading to the firehouse tonight or running errands around your community, take a good look around. Ask your self a simple question; “How well do you know the buildings, structures and occupancies in your response jurisdiction?”
  • Be honest, do you really understand how those “older residential” structures were built and understand how fire travels and impacts your fireground operations?
  • Are your aware of the newest features of engineered structural support systems being constructed within that new set of homes going up in your second-due area?
  • Are you aware, that vacant office building is being converted into a light manufacturing and assembly business?
  • How about those unoccupied store fronts and businesses that have recently closed up due to the tough economic times…. any special hazards or operational concerns to your company should you get a dispatch to respond?
  • Have the senior members of your station or department shared their stories of operations and incidents at various buildings around your district or community?
  • Did you listen to them, or were you quick to dismiss those “old war stories”. There’s a wealth of “pre-planning’ nuggets hidden in those stories. Take the time to listen, remember or postulate
  • Take a good look around….think about any given building, the one across the street that you’re looking at while you waited for the traffic light to change; Think about a fire in that same building.
  • Do you really understand how it will truly perform under combat structural fire conditions?
  • What’s the building’s collapse profile?
  • How much operational time will you have? Will you need?
  • What’s the fire load package size?
  • What are your concerns for rapid fire extension, extreme fire behavior and vent path issues that amy affect firefighter safety?
  • What dynamic risk assessment factors will you have to deal with?
  • How safe is it for you to engage in interior operations upon your arrival?
  • How can this building, its occupancy and structural system hurt, my team, my company, my firefighters, my department, me?

Sometimes things aren’t as obvious as them seem. You may have responded and operated at numerous incidents at a wide variety of buildings in your response area, or very few; some routine, others maybe more demanding…the question remains, “What do you really know about your buildings?” Your life may one day depend on what you actually do know or recollect. Take a good look around.

Pre-Incident planning is formulative to any effective fire service organization. A good staring point is to look at the NFPA 1620 Recommended Practice for Pre-Incident Planning document. ( NFPA Codes and Standards, HERE)

The purpose of the NFPA 1620 Recommended Practice for Pre-Incident Planning document is to aid in the development of a pre-incident plan to help responding personnel effectively manage emergencies with available resources and should not be confused with fire inspections, which monitor code compliance.

The Pre-Incident Plan document is developed by gathering general and detailed data used by responding emergency service personnel to determine the necessary resources and actions necessary to mitigate anticipated emergencies at a specific facility, structure or occupancy.The Pre-Incident Plan document can contain a variety of useful information related to the construction features and systems, building materials and components, occupancy, layout and floor plan, access/egress, built-in protective, detection and suppression systems, special hazards, fire loading, fire suppression flow needs, pre-determined resource needs, exposure factors, etc.The Pre-Incident Plan document can be as simple or detailed as occupancy and/or operational factors dictate.

The import issue here is that you HAVE Pre-Incident Plan documents available for at the very least targeted or high hazard occupancies and buildings, and that they have been updated at some periodic frequency. There’s nothing worst that arriving at a particular box alarm, pulling open the pre-fire “binder” and finding the occupancy was last planned twenty years ago at best.

The 2007 Deutsche Bank Building fire in lower Manhattan, New York City that resulted in the LODD of FDNY Fr. Joseph Graffagnino and Fr. Robert Beddia, stressed the need for timely and accurate pre-incident plans, when a seven alarm fire progressed through the 40 story high-rise building that was in the process of being deconstructed.An informative Training PDF download is attached that provides Operational Safety Considerations at Demolition and Deconstruction sites.

The full power-point version is available for direct download HERE.

Think about your Buildings and Occupancies and correlate your incident operations using an effect acronym called BECOME SAFE.

Our world has evolved and changed. There are a variety of technological and sociological demands that create a continuing element of change in the built environment and our infrastructure. With these changes and demands come the requirements to assess these vulnerabilities, hazards, threats and dangers with effective and dynamic risk management and competent command and control.

These changes influence the way we do business in the street, the interface-up close and personal with the buildings in your community and equate to the risks and hazards you and your personnel will be confronted with and the level of safety afforded them during incident operations. Dynamic Risk and Command Management and the integration of BECOME SAFE concepts, ingredients for safer operations.

With the advancements in technology, software and programs, there is a vast extent of options and financial levels available to all organizations to develop publish and revise pre-incident planning documents. The key safety message here is that Pre-Fire Plans and Incident Plans can provide a significant margin of support to you during incident operations and can increase firefighter safety, reduce operational risk and aid in the risk management and command management of a give incident.

Regardless of your agency and respond district size, complexity of simplicity, Pre-Incident Plans are a necessary part of modern firefighting and all-hazards operations. An informative planning flow chart is available within the NFPA 1620 document, Figure 4.2.3. ( Order the NFPA 1620 document through the NFPA (HERE)

  • An informative Pre-Fire Planning article by Battalion Chief Michael Lee is available HERE

Spend time touring through construction sites as you monitor the progress of a building or occupancy going up.

Look at the manner in which structural support systems are fabricated and assembled. Observe the types of materials that are being used and how they are assembled to form rooms and compartments within the structure.

Take a good look at the manner in which floor and roof systems are constructed, these will become mission critical informational items that can be used to determine your operational profile and formulate your incident action plans. Keep abreast of changes, renovations and alternations to buildings and structures, especially as commercial and business occupancies change owners. These are special areas of concerns on wide latitude of safety and operational considerations.

With the continued challenges in these economic times, pay very close attention to the state of your vacant and unoccupied structures. A change in strategic and tactical deployment considerations MUST be instituted; it shouldn’t be business as usual in these structures.

  • Keep apprised of different types of building materials and construction used in your community.
  • Document those conditions and aspects and train your personnel to understand the occupancies within your community.
  • Understand the Structural AnatomyTM of your buildings and occupancies.
  • The operative response to the opening question this time next year will be this: “What do you “really” know about the buildings in your district?” …The answer will hopefully be…”A lot!”

Are you keeping up the latest construction terminology, materials and methods? Changes are you are not. But I can assure you, somewhere in your community, jurisdiciton, first, second or third-due or mutual aid area; there is new construction features, systems, components and materials being used that will affect the manner you which a structural fire will need to be addressed; The Rules of Structural Fire Suppression have changed- but know has told you…yet.

Of the many issues affecting the Fire Service, the prevailing challenge that has a pronounced impact on operational safety is the assimilation of engineered structural systems (ESS) into mainstream building design and construction. The presence of engineered structural systems (ESS) are no longer considered to be an innocuous feature in a given building or occupancy; it is the predominate feature in nearly all current construction, renovation and adaptive reuse or infill applications. It has become far more than just concerning ourselves with the presence of a simple light-weight or “engineered” truss roof system or a wood I-beam  floor assembly.

There is a new lexicon of building construction components and systems that must be added to your operational safety vocabulary and incident action plans. There is a new terminology, applications and a knowledge base to learn that will support operational excellence and support the integrity of incident safety performance of companies and personnel. Do you know what they represent and how these components, assemblies and systems may affect or influence an incident?

Take a tour of your local construction sites; You’ll be surprised what you’ll see

The fire service continues to apply the term “light weight construction” to a wide variety of building construction and systems. This expression has become a miss-application of both term and the correlation of risk and severity related to operational profiling. In other words, we apply and express the use of “light weight construction” for all types of engineered components, systems, designs and assemblies in nearly all types of building construction and occupancy use.

Although the roots of the term can be traced back to the early 1980′s, and its application to the (then) emerging use of trussed roofing systems and the advent of wood I-beam floor supports (sans solid dimensional lumber joists), the use of the terminology in today’s context of risk assessment, strategic and tactical management and deployment models and within the context of incident operational tactics is no longer applicable, valid or suitable. It must be expanded into a more specific and descriptive level of classification and correlation.

For the most part, when discussing buildings and occupancies, aside from classifications related to code type or class as an element of fire resistance; the emphasis has been to differentiate between conventional and engineered construction, and the application of the term “light weight construction”. I continue advocating and promoting through my lectures that it’s much more than this when looking at the spectrum of construction and the structural anatomy of buildings. Current and past generations of buildings, construction and occupancies can be more accurately differentiated and classified within six (6) expanding categories in the following Building Construction Systems;

  • Heritage:              Pre-1900
  •  Legacy:                1900-1949
  • Conventional:      1950-1979
  • Engineered:         1980-current 2011
  • Blended Hybrid:  2005- current 2011

         
We’ll discuss these six classifications in greater details in a series of future postings and expand the level of details on the CommandSafety.com and Buildingsonfire.com sites.

Our current generation of buildings, construction and occupancies are not as predictable as past “conventional” construction, therefore risk assessment, strategies and tactics must change to address the advancement of new rules of combat structural fire engagement. But if you don’t understand or know what and how those changes in predictability have occurred, you may be operating with a false sense of operational risk and safety margin.

It’s a Lot More than just talking about “Light Weight” Construction….

 Just Look Over your Shoulder….

I’ve commented with more than a few postings on the issues related to engineer building construction components and assemblies. I posed some questions related to Engineered Structural Assemblies & Systems (ESS) and asked if you knew what they represent and how these components, assemblies and systems may affect or influence incident operations.

I also presented some information on the pioneering efforts and quantitative results of the Underwriters Laboratory (UL) engineers and fire service representatives from the Chicago Fire Department, HERE and HERE.

If you’ve spent any amount of time reading through the NIOSH Fire Fighter Fatality Investigation and Prevention Program, LODD Reports or have invested time and effort to look through the data base of near miss reports and ROTW at the National Firefighter Near-Miss Reporting System, you’d recognize the magnitude of the issues and multi-faceted challenges confronting the U.S. Fire Services in the areas of engineered structural assemblies, components and building features.

Paul Comb’s editorial image provides a poignant and distressing reality that the fire service needs to come to terms with, addressing and implementing the necessary components that assimilating refined combat firefighting techniques and methodologies; that align with the risks and hazards presented by current and emerging construction techniques, materials and consumer lifestyles that comprise our buildings and occupancies. We need to start looking over our shoulders; we need redefined strategies and tactics for today’s buildings and occupancies. When we do have the opportunity to engage in firefighting with the dragon; we may not recognize the dragon has changed, it has evolved. Yet we stand poised to engage or take-on the dragon with faulted incident operations, strategic plans and tactical intentions that provide less than adequate results.

In those situations where we are deficient or we achieved less than expected results, we continue to miss the apparent or root causes and fall back on perceived notions and excuses. Building Knowledge = Firefighter Safety; Understanding today’s building construction, fire dynamics, fire loading and behaviors and instituting appropriate firefighting methodologies, we can achieve safe and successful fireground operations.

Better Look Over your Shoulder

 

  •   Have you and your company, battalion or department discussed limiting factors, enhanced firefighting tactics or operational experiences related to engineered systems, past fires, observed new construction or renovations and what it all means to your assigned duties or company assignments?
  • Are you and your company adequately trained to address “modern” construction, occupancies and conditions or is a much bigger dragon lurking in the shadows?

 Remember, the Predictability of Performance and the combat firefighting based upon Occupancy Risk not Occupany Type.

  

Remember its Occupancy RISK not Occupancy TYPE

 

Here’s the New Formula for Fire Fighter Safety ; Bk = f2S; Building Knowledge = Firefighter Safety

 

STOP THE ENTERTAINMENT

There’s another factor contributing to unsafe practices, one that we rarely talk about. In short, we need to stop “entertaining” ourselves during fire suppression operations and instead focus on comprehending and reacting to evolving risks. Rather than practicing appropriate risk management, it is suggested that some individuals employ adverse behaviors that occur on a tactical level while Incident Commanders and Company Officers believe firefighters are completing their assigned tasks, thus compromising accountability.

These behaviors include;

Tactical amusement: engaging in any practice or tactic during fire suppression, support tasks or operations that places personnel at risk for the sake of entertainment. 

Tactical diversion: diverting from an assignment while engaging in fire suppression, support tasks or operations in such a way that places personnel at risk.

Tactical circumvention: deliberately “getting around” an assignment or disregarding risk assessment and incident action plans.

  

Here’s the expanded versions in case this is the first time you’ve seen them;

TACTICAL AMUSEMENT*tak-ti-kəl ə- *myüz-mənt

1: of or relating to structural fireground tactics: as a (1) a means of amusing or entertaining during fire suppression, support tasks or operations that places personnel at risk

2: the condition of being amused while engaging in fire suppression, support tasks or operations that places personnel at risk

3: pleasurable diversion while engaging in fire suppression, support tasks or operations: entertainment; that places personnel at risk

TACTICAL DIVERSION*tak-ti-kəl də- *vər-zhən

1: the reckless act or an instance of diverting from an assignment, task, operation or activity while engaging in fire suppression, support tasks or operation for the sake of amusing or entertainment; that places personnel at risk

2: the reckless act of self determined task operations that diverts or amuses from defined risk assessment and incident action plans; that places personnel at risk

TACTICAL CIRCUMVENTION*tak-ti-kəl sər-kəm- *ven(t)-shən

1: to deliberately manage to get around especially by ingenuity or approach that diverts for the purpose of amusing; assignment, operations or tasks that countermand or disregard defined risk assessment and incident action plans; that places personnel at risk

  

TACTICAL PATIENCE (NEW) This is a new one that’s called Tactical Patience…I’ll post more on Tactical Patience  later this month.

If we’re going to reduce firefighter injuries and deaths, we must be doing the right thing, at the right time, for the right reasons, and in the right place. We must stop the entertainment.

” The demands and requirements of modern firefighting will continue to require the placement of personnel within situations and buildings that carry risk, uncertainty and inherent danger. Fire suppression tactics must be adjusted for the rapidly changing methods and materials impacting all forms of building construction, occupancies and structures.

The need to redefine the art and science of firefighting is nearly upon us. Some things do stand the test of time, others need to adjust, evolve and change.

Not for the sake of change only, but for the emerging and evolving buildings, structures and occupancies being built, developed or renovated in our communities.

It’s no longer just brute force and sheer physical determination that define structural fire suppression operations.

Aggressive firefighting must be redefined and aligned to the built environment and associated with goal oriented tactical operations that are defined by risk assessed and analyzed tasks that are executed under battle plans that promote the best in safety practices and survivability within know hostile structural fire environments, while maintaining the values and tradition that defines the fire service.”

  

 

Remember one thing…Don’t ever under estimate what you might encounter on any structure fire, or what might change in a second;  focus on the Occupancy Risk not the Occupancy Type….. And Know your buildings, your team and your capabilities

Firefighter Killed In Roof Collapse at Church Fire

1 comment

Tabernacle of Praise church in Muncie, Indiana burns while a firefighter jumps out of a broken window. .(Maria Strauss/The Star Press)

A major fire took command of the roof area at Tabernacle of Praise Church on the southside of Muncie, Indiana on Wednesday June 15, 2010. The fast moving fire caused significant the structural support of the roof system to collapse during fire suppression operations. This resulted in one firefighter becoming trapped with later reports indicating the firefighter died in the lin of duty.

The fire was reported around 3:55 p.m. The Muncie Fire Department was leading efforts to battle the blaze with help from surrounding volunteer departments, who are bringing water to the incident site on tanker trucks. The structure that collapsed and on fire was sanctuary. Published reports indicate that the church was hand built by church members. Radio dispatch indicated at 4:15 p.m. a firefighter was missing after the roof collapsed.

Dispatchers learned of the fire shortly before 4 p.m., and one reported the firefighter went missing after the roof collapsed about 15 minutes later, the newspaper reported.

Fire Behavior 101; Taking it to the Streets

Fire Behavior

Fire Dynamics

Fire Dynamics is the study of how chemistry, fire science, material science and the mechanical engineering disciplines of fluid mechanics and heat transfer interact to influence fire behavior.

In other words, Fire Dynamics is the study of how fires start, spread and develop. But what exactly is a fire?

Defining Fire

Fire can be described in many ways – here are a few:

  • NFPA 921: ”A rapid oxidation process, which is a chemical reaction resulting in the evolution of light and heat in varying intensities.”
  • Webster’s Dictionary: “A fire is an exothermic chemical reaction that emits heat and light”

Fire can also be explained in terms of the Fire Tetrahedron – a geometric representation of what is required for fire to exist, namely, fuel, an oxidizing agent, heat, and an uninhibited chemical reaction.

Measuring Fire

Heat Energy is a form of energy characterized by vibration of molecules and capable of initiating and supporting chemical changes and changes of state (NFPA 921).

In other words, it is the energy needed to change the temperature of an object – add heat, temperature increases; remove heat, temperature decreases.

Heat energy is measured in units of Joules (J), however it can also be measured in Calories (1 Calorie = 4.184 J) and BTU’s (1 BTU = 1055 J).

Temperature is a measure of the degree of molecular activity of a material compared to a reference point.

Temperature is measured in degrees Farenheit (melting point of ice = 32 º F, boiling point of water = 212 º F) or degrees Celsius (melting point of ice = 0 º C, boiling point of water = 100 º C).

Heat Release Rate (HRR) is the rate at which fire releases energy – this is also known as power. HRR is measured in units of Watts (W), which is an International System unit equal to one Joule per second. 

Depending on the size of the fire, HRR is also measured in Kilowatts (equal to 1,000 Watts) or Megawatts (equal 1,000,000 Watts).

Heat Flux is the rate of heat energy transferred per surface unit area – kW/m2.

(930 F - 2500 F)

10 CANDLES

HRR: ~ 800 W

Heat Transfer

Heat transfer is a major factor in the ignition, growth, spread, decay and extinction of a fire.

It is important to note that heat is always transferred from the hotter object to the cooler object - heat energy transferred to and object increases the object’s temperature, and heat energy transferred from and object decreases the object’s temperature.

CONDUCTION

Conduction is heat transfer within solids or between contacting solids.

Conduction          Firefighter Conduction

 

The governing equation for heat transfer by conduction is:

Conduction Equation

Where T is temperature (in Kelvin), A is the exposure area (meters squared), L is the depth of the solid (meters), and k is a constant that unique for different materials know as the thermal conductivity and has units of (Watts/meters*Kelvin).

Thermal Conductivity of Common Materials

Copper = 387
Gypsum = 0.48
Steel = 45.8
Oak = 0.17
Glass = 0.76
Pine = 0.14
Brick = 0.69
PPE = 0.034 – 0.136
Water = 0.58
Air = 0.026

CONVECTION

Convection is heat transfer by the movement of liquids or gasses.

Convection          Firefighter Convection

The governing equation for heat transfer by convection is:

Convection Equation

Where T is temperature (in Kelvin), A is the area of exposure (in meters squared), and h is a constant that is unique for different materials known as the convective heat transfer coefficient, with units of W/m2*K.

These values are found empirically, or, by experiment.

For free convection, values usually range between 5 and 25. But for forced convection, values can range anywhere from 10 to 500.

RADIATION

Radiation is heat transfer by electromagnetic waves.

Radiation          Firefighter Radiation

The governing equation for heat transfer by radiation is:

Radiation Equation

Where T is temperature (in Kelvin), A is the area of exposure (in meters squared), α is the thermal diffusivity (a measure of how quickly a material will adjust it’s temperature to the surroundings, in meters squared per second) and ε is the emissivity (a measure of the ability of a materials surface to emit energy by radiation).

Fire Phenomena

Fire Development is a function of many factors including: fuel properties, fuel quantity, ventilation (natural or mechanical), compartment geometry (volume and ceiling height), location of fire, and ambient conditions (temperature, wind, etc).

Traditional Fire Development
The Traditional Fire Development curve shows the time history of a fuel limited fire. In other words, the fire growth is not limited by a lack of oxygen. As more fuel becomes involved in the fire, the energy level continues to increase until all of the fuel available is burning (fully developed).

Then as the fuel is burned away, the energy level begins to decay.

The key is that oxygen is available to mix with the heated  gases (fuel) to enable the completion of the fire triangle and the generation of energy.

Watch

Windows: Traditional Fire Development in a Compartment Fire 

Mac: Traditional Fire Development in a Compartment Fire

Fire Behavior in a Structure
The Fire Behavior in a Structure curve demonstrates the time history of a ventilation limited fire. In this case the fire starts in a structure which has the doors and windows closed.Early in the fire growth stage there is adequate oxygen to mix with the heated gases, which results in flaming combustion. As the oxygen level within the structure is depleted, the fire decays, the heat release from the fire decreases and as a result the temperature decreases.

When a vent is opened, such as when the fire department enters a door, oxygen is introduced. 

The oxygen mixes with the heated gases in the structure and the energy level begins to increase.

This change in ventilation can result in a rapid increase in fire growth potentially leading to a flashover (fully developed compartment fire) condition.

 Typical Fire Behavior

Watch

Windows: Fire Behavior in a Structure (Ventilation limited)

Flashover is the transition phase in the development of a contained fire in which surfaces exposed to the thermal radiation, from fire gases in excess of 600° C, 

reach ignition temperature more or less simultaneously and fire spreads rapidly through the space.

This is the most dangerous stage of fire development.

UL Ventilation and Fire Behavior Full Scale Testing

 

Impact of Ventilation on Fire Behavior in Legacy and Contemporary Residential Construction

For many of you that have been following my writings and perspectives on building construction, firefighting, command risk management and operational excellence for firefighter safety have long recognized that I have been promoting and advocating the fact the fireground is changining, our stratgies and tactics demand change adn does the demand for increased knowledge within the areas of building construction, fire dynamics, while integrating the art and science of firefighting. The most recent release of the testing report from Underwriters Laboratories; Impact of Ventilation on Fire Behavior in Legacy and Contemporary Residential Construction and the accompaning emphirical data further validates assumptions and presmises that many of us shared based upon field obervations and first hand incident operations related to the dramatic changes being witnessed as a result of operational challenges in a wide varity of occupanies and building types.

This material is a must read for all emerging and practicing company and command officers ( for starters) to being grasping the magnitude and extent of quantifiable data that supports the premise that combat fire engagement and suppression operations and the rules of engagement are going to change and that change is fast approaching.

Considerations for Tactical Patience and Adaptive Fireground Management are continued themes I will expand upon in future postings….

Here’s the executive summary of the report and findings from UL. For an download of the entire UL Report, go HERE.

Under the United States Department of Homeland Security (DHS) Assistance to Firefighter Grant Program, Underwriters Laboratories examined fire service ventilation practices as well as the impact of changes in modern house geometries. There has been a steady change in the residential fire environment over the past several decades. These changes include larger homes, more open floor plans and volumes and increased synthetic fuel loads. This series of experiments examine this change in fire behavior and the impact on firefighter ventilation tactics. This fire research project developed the empirical data that is needed to quantify the fire behavior associated with these scenarios and result in immediately developing the necessary firefighting ventilation practices to reduce firefighter death and injury.

Two houses were constructed in the large fire facility of Underwriters Laboratories in Northbrook, IL. The first of two houses constructed was a one-story, 1200 ft2, 3 bedroom, 1 bathroom house with 8 total rooms. The second house was a two-story 3200 ft2, 4 bedroom, 2.5 bathroom house with 12 total rooms. The second house featured a modern open floor plan, two-story great room and open foyer. Fifteen experiments were conducted varying the ventilation locations and the number of ventilation openings. Ventilation scenarios included ventilating the front door only, opening the front door and a window near and remote from the seat of the fire, opening a window only and ventilating a higher opening in the two-story house. One scenario in each house was conducted in triplicate to examine repeatability.

The results of these experiments provide knowledge for the fire service for them to examine their thought processes, standard operating procedures and training content. Several tactical considerations were developed utilizing the data from the experiments to provide specific examples of changes that can be adopted based on a departments current strategies and tactics.

This fire research project developed the empirical data that is needed to quantify the fire behavior associated with these scenarios and result in immediately developing the necessary firefighting ventilation practices to reduce firefighter death and injury.

  • Two houses were constructed in the large fire facility of Underwriters Laboratories in Northbrook, IL.
  • The first of two houses constructed was a one-story, 1200 ft2, 3 bedroom, 1 bathroom house with 8 total rooms.
  • The second house was a two-story 3200 ft2, 4 bedroom, and 2.5 bathroom house with 12 total rooms.
  • The second house featured a modern open floor plan, two story great room and open foyer.

 Fifteen experiments were conducted varying the ventilation locations and the number of ventilation openings. Ventilation scenarios included ventilating the front door only, opening the front door and a window near and remote from the seat of the fire, opening a window only and ventilating a higher opening in the two-story house.

One scenario in each house was conducted in triplicate to examine repeatability. The results of these experiments provide knowledge for the fire service for them to examine their thought processes, standard operating procedures and training content. Several tactical considerations were developed utilizing the data from the experiments to provide specific examples of changes that can be adopted based on a departments current strategies and tactics.

The tactical considerations addressed include:

  • Stages of fire development:The stages of fire development change when a fire becomes ventilation limited.
    • It is common with today’s fire environment to have a decay period prior to flashover which emphasizes the importance of ventilatio
  • Forcing the front door is ventilation: Forcing entry has to be thought of as ventilation as well.
    • While forcing entry is necessary to fight the fire it must also trigger the thought that air is being fed to the fire and the clock is ticking before either the fire gets extinguished or it grows until an untenable condition exists jeopardizing the safety of everyone in the structure.
  • No smoke showing:A common event during the experiments was that once the fire became ventilation limited the smoke being forced out of the gaps of the houses greatly diminished or stopped all together.
    • No some showing during size-up should increase awareness of the potential conditions inside.
  • Coordination:If you add air to the fire and don’t apply water in the appropriate time frame the fire gets larger and safety decreases.
    • Examining the times to untenability gives the best case scenario of how coordinated the attack needs to be.
    • Taking the average time for every experiment from the time of ventilation to the time of the onset of firefighter untenability conditions yields 100 seconds for the one-story house and 200 seconds for the two-story house
    • In many of the experiments from the onset of firefighter untenability until flashover was less than 10 seconds.
    • These times should be treated as being very conservative. If a vent location already exists because the homeowner left a window or door open then the fire is going to respond faster to additional ventilation opening because the temperatures in the house are going to be higher.
    • Coordination of fire attack crew is essential for a positive outcome in today’s fire environment.
  • Smoke tunneling and rapid air movement through the front door:Once the front door is opened attention should be given to the flow through the front door.
    • A rapid in rush of air or a tunneling effect could indicate a ventilation limited fire.
  • Vent Enter Search (VES):During a VES operation, primary importance should be given to closing the door to the room.
    • This eliminates the impact of the open vent and increases tenability for potential occupants and firefighters while the smoke ventilates from the now isolated room.
  • Flow paths: Every new ventilation opening provides a new flow path to the fire and vice versa.
    • This could create very dangerous conditions when there is a ventilation limited fire.
  • Can you vent enough?:In the experiments where multiple ventilation locations were made it was not possible to create fuel limited fires.
    • The fire responded to all the additional air provided.
    • That means that even with a ventilation location open the fire is still ventilation limited and will respond just as fast or faster to any additional air.
    • It is more likely that the fire will respond faster because the already open ventilation location is allowing the fire to maintain a higher temperature than if everything was closed. In these cases rapid fire progression if highly probable and coordination of fire attack with ventilation is paramount.
  • Impact of shut door on occupant tenability and firefighter tenability:Conditions in every experiment for the closed bedroom remained tenable for temperature and oxygen concentration thresholds.
    • This means that the act of closing a door between the occupant and the fire or a firefighter and the fire can increase the chance of survivability.
    • During firefighter operations if a firefighter is searching ahead of a hoseline or becomes separated from his crew and conditions deteriorate then a good choice of actions would be to get in a room with a closed door until the fire is knocked down or escape out of the room’s window with more time provided by the closed door
  • Potential impact of open vent already on flashover time:All of these experiments were designed to examine the first ventilation actions by an arriving crew when there are no ventilation openings.
    • It is possible that the fire will fail a window prior to fire department arrival or that a door or window was left open by the occupant while exiting.
    • It is important to understand that an already open ventilation location is providing air to the fire, allowing it to sustain or grow.
  • Pushing fire:There were no temperature spikes in any of the rooms, especially the rooms adjacent to the fire room when water was applied from the outside. It appears that in most cases the fire was slowed down by the water application and that external water application had no negative impacts to occupant survivability.
    • While the fog stream “pushed” steam along the flow path there was no fire “pushed”.
  • No damage to surrounding rooms:Just as the fire triangle depicts, fire needs oxygen to burn.
    • A condition that existed in every experiment was that the fire (living room or family room) grew until oxygen was reduced below levels to sustain it.
    • This means that it decreased the oxygen in the entire house by lowering the oxygen in surrounding rooms and the more remote bedrooms until combustion was not possible.
    • In most cases surrounding rooms such as the dining room and kitchen had no fire in them even when the fire room was fully involved in flames and was ventilating out of the structure.

Comparison of Modern and Legacy Home Furnishings

An experiment was conducted with two side by side living room fires. The purpose was to gain knowledge on the difference between modern and legacy furnishings. The rooms measured 12 ft by 12 ft, with an 8 ft ceiling and had an 8 ft wide by 7 ft tall opening on the front wall. Both rooms contained similar amounts of like furnishings.

The modern room was lined with a layer of ½ inch painted gypsum board and the floor was covered with carpet and padding.

  • The furnishings included a microfiber covered polyurethane foam filled sectional sofa, engineered wood coffee table, end table, television stand and book case.
  • The sofa had a polyester throw placed on its right side. The end table had a lamp with polyester shade on top of it and a wicker basket inside it.
  • The coffee table had six color magazines, a television remote and a synthetic plant on it.
  • The television stand had a color magazine and a 37 inch flat panel television.
  • The book case had two small plastic bins, two picture frames and two glass vases on it.
  • The right rear corner of the room had a plastic toy bin, a plastic toy tub and four stuffed toys.
  • The rear wall had polyester curtains hanging from a metal rod and the side walls had wood framed pictures hung on them.

The legacy room was lined with a layer of ½ inch painted cement board and the floor was covered with unfinished hardwood flooring.

  • The furnishings included a cotton covered, cotton batting filled sectional sofa, solid wood coffee table, two end tables, and television stand.
  • The sofa had a cotton throw placed on its right side.
  • Both end tables had a lamp with polyester shade on top of them.
  • The one on the left side of the sofa had two paperback books on it.
  • A wicker basket was located on the floor in front of the right side of the sofa at the floor level.
  • The coffee table had three hard-covered books, a television remote and a synthetic plant on it.
  • The television stand had a 27 inch tube television.
  • The right front corner of the room had a wood toy bin, and multiple wood toys.
  • The rear wall had cotton curtains hanging from a metal rod and the side walls had wood framed pictures hung on them.

Both rooms were ignited by placing a lit stick candle on the right side of the sofa. The fires were allowed to grow until flashover. The modern room transitioned to flashover in 3 minutes and 30 seconds and the legacy room at 29 minutes and 30 seconds.

Analytical Study Reveals Patterns in U.S Firefighter Fatalities

1 comment

While the number of structural fires in the United States continues to decline, firefighter line of duty deaths (LODD) do not exhibit the same rate of proportion decline. A review of both NFPA and USFA Firefighter LODD annual reports, statistics and retrospective studies and analysis suggest a noted change in the adverse trends noted for a number of previous years, but we are lagging in achieving the goals established by the NFFF’s Everyone Goes Home Program and initiatives.

 A recently published study and research conducted at the University of Georgia may provide insights and help explain why.

 Researchers in the UGA College of Public Health found that cultural factors in the work environment that promote getting the job done as quickly as possible with whatever resources available lead to an increase in line-of-duty firefighter fatalities.

“Firefighting is always going to be a hazardous activity, but there’s a general consensus among firefighting organizations and among scientific organizations that it can be safer than it is, “according to study co-author David DeJoy, of the Workplace Health Group in the College of Public Health.

The research, published in the May edition of the journal Accident Analysis and Prevention, examined data gathered from 189 firefighter fatality investigations conducted by the National Institute of Occupational Safety and Health between 2004 and 2009.

Each NIOSH investigation gives recommendations directed at preventing future firefighter injuries and deaths. The researchers looked at the high-frequency recommendations and linked them to important causal and contributing factors of the fatalities.

The following is the Abstract from the Line of duty deaths among U.S. Firefighters: An analysis of fatality investigations, published by Kumar Kunadharaju, Todd D. Smith and David M. Dejoy.

Inadequate preparation for/anticipation of adverse events during operations,

Abstract

More than 100 firefighters die in the line-of-duty in the U.S. each year and over 80,000 are injured. This study examined all firefighter fatality investigations (N=189) completed by the National Institute for Occupational Safety and Health (NIOSH) for fatalities occurring between 2004 and 2009.

  • These investigations produced a total of 1167 recommendations for corrective actions.
  •  Thirty-five high frequency recommendations were derived from the total set: six related to medical fatalities and 29 to injury-related fatalities.
  • These high frequency recommendations were mapped onto the major operational components of firefighting using a fishbone or cause-effect diagram.
  • Over 70% of the 30 non-external recommendations were categorized within the personnel and incident command components of the fishbone diagram.

Root cause techniques suggested four higher order causes:

  1. under-resourcing,
  2.  inadequate preparation for/anticipation of adverse events during operations,
  3. incomplete adoption of incident command procedures, and
  4. sub-optimal personnel readiness.

These findings are discussed with respect to the core culture of firefighting. (Copyright © 2011, Elsevier Publishing)

Excerpt from the study introduction

The United States depends on about 1.1 million career and volunteer firefighters to protect its citizens and property from losses caused by fire. Firefighting is considered to be one of the most stressful and dangerous occupations. Each year more than 100 firefighters die in the line of duty and over 80,000 are injured (Karter and Molis, 2009; United States Fire Administration, 2009). The fatality rate for firefighters is three times worse than for the general working population (International Association of Firefighters, 2001).

Advances in technology, personal protective equipment, engineering controls, environmental management, medical care, and safety legislation produced substantial reductions in fatalities during the 1970s and 1980s; however, these numbers have not improved during the past 25 years and have been trending upward for the past decade. Without question, firefighting is high hazard work, but it is unique beyond this. In most high hazard work situations, the goal is hazard avoidance. In contrast, for firefighting, the principal work activity is hazard engagement, which is usually further complicated by extreme time pressure.

High hazard work situations

The customary safety strategy in many high hazard work situations is to implement multiple safety measures, or what is sometimes referred to as: “defenses in depth” (Rasmussen, 1997; Reason, 1997). That is, several layers of precautions are put in place to protect the workers and the integrity of the overall system, even when components fail or errors occur. There is little protective redundancy in firefighting, and risks to personnel must continually be assessed and reassessed as the fire situation develops and changes, often with little predictability or advanced warning. Most efforts to protect firefighters fall into two general categories: preparative measures and operational measures.

Preparative measures encompass actions that prepare the firefighters to do their work in as safe a manner as possible. This would include personnel selection and placement, training, professional socialization, as well as the provision of personal protective equipment (PPE) and other safety devices. Operational measures focus on maintaining an adequate margin of safety during actual firefighting activities. This would include adherence to various standard operating procedures (SOPs), continued monitoring of risk–benefit ratios, communications, staffing, and other command and control activities.

As part of the effort to reduce firefighter line-of-duty fatalities, the United States Fire Administration (USFA) collects and evaluates information regarding line-of-duty (LODD) firefighter fatalities and publishes the data in the annual firefighter fatality reports (e.g., United States Fire Administration, 2009)

In 1998, Congress appropriated funding to the National Institute for Occupational Safety and Health (NIOSH) to conduct independent, onsite investigations of firefighter line-of-duty (LOD) deaths (National Institute for Occupational Safety and Health, 2009). The investigations conducted as part of the NIOSH Firefighter Fatality Investigation and Prevention Program (FFFIPP) are voluntary and not all fatalities are investigated. Cases are selected for investigation using a decision algorithm (National Institute for Occupational Safety and Health, 2009), with the primary goal not to find fault or assign blame, but rather to learn from these events and to formulate recommendations directed at preventing future firefighter injuries and deaths.

Since the program’s inception, NIOSH has completed over 470 fatality investigations. There have been several prior efforts to compile and analyze various portions of this accumulated database. Hodous and colleagues (Hodous et al., 2004) reviewed firefighter fatalities from 1998 to 2001 and synthesized NIOSH recommendations for cases involving structural firefighting activities.  

 
 

 
 
 

Risk and Culture

 

These researchers identified eight frequently occurring recommendations that highlighted three general areas of concern:

(1) use and enforcement of standard operating procedures (SOPs) related to structural firefighting techniques and strategies;

(2) adequate staffing and adherence to contemporary incident command practices, and

(3) increased attention to communications and personnel accountability and rescue.

  • Peterson and colleagues (Peterson et al., 2006) examined recommendations from the first five years of fatality investigations (1999–2003).
  • Their analysis identified 31 “key” recommendations, 22 involving traumatic injury fatalities and 9 involving cardiovascular fatalities.
  • These were further reduced to 17 sentinel recommendations involving training, standard operating procedures, safety practices, and the safety environment of fire departments.
  • More recently, Ridenour and associates (Ridenour et al., 2008) reviewed all investigations completed between 1998 and 2005.
  • This analysis highlighted ten categories of recommendations, two focusing on medical cases and the other eight focusing on traumatic injuries.

The clear majority of medically-related fatalities involve cardiovascular events and these have produced two predominant recommendations: the need for improvements in medical screening, and the need for wider adoption of fitness/wellness programming for firefighters.

These are both preparative measures designed to identify and address cardiovascular risk in operational personnel. Trauma cases, on the other hand, have yielded a much more diverse array of recommendations and a less clear picture of high priority needs. These recommendations address both preparative and operational measures, and cover a broad territory that includes command and control functions, operations and tactics, and equipment and resources.

  • The present study continues this line of inquiry but expands it in several ways.
  • The first objective was to determine the extent to which the incidents investigated by NIOSH are representative of all firefighter LOD fatalities.
  • NIOSH investigations are voluntary on the part of the fallen firefighter’s organization and NIOSH does not have sufficient resources to investigate all fatalities.
  • This issue has potentially important implications for the generalizability of any key recommendations extracted from the accumulated database of reports.
  • The second objective was to better describe the procedures used to derive key or sentinel recommendations.

In the analyses described above, only limited procedural details were provided on how the high frequency recommendations were actually determined.

The Fire Service Culture

For example, it would be useful to know how frequent the high frequency recommendations were, not only in absolute terms but also relative to other recommendations. Since most investigations contain several recommendations, it would be useful to know how similar recommendations were handled within and across investigations. The third objective involved the issue of causation.

The recommendations contained in these reports speak primarily to the “what” – that is, what needs to be done, not done, done better, or done differently in the future to reduce risk.

These recommendations almost always draw upon contemporary knowledge and accepted best practices in the firefighting and emergency response professional communities. Logically, it should be possible to link high frequency recommendations to causal factors or clusters of causal factors. Therefore, we were interested in determining whether insights into important causal factors could be extracted from these reports.

Identification of such factors is a requisite step in the development of effective prevention strategies (Higgins et al., 2001). With these objectives forming the organizing framework, the present research sought to examine NIOSH investigations for the years 2004–2009. This time period was chosen to complement the previous analyses and to provide a current perspective.

The study analyzed the investigations in terms of the core culture of the firefighting profession. Firefighting culture should not be construed as one of negligence, said DeJoy, but one based on a long-standing tradition of acceptance of risk. A job that relies on extreme individual efforts and has too few resources leads to the chronic condition of doing too much with too little, he said.

  • “If you get used to taking risks, it’s easy to take a little more risk,” DeJoy said.
  • “Most of the time when we take risks, like walking across the street or driving a car, nothing bad happens.
  • This level of risk gets ratcheted up and becomes part of normal activity.” Acceptance of risk becomes extremely perilous in a situation in which adverse events can happen at any time and margins of safety are very thin, he added.

Firefighter deaths dropped in the 1970s and 1980s, largely due to improvements in protective clothing, breathing equipment and radio communication, explained DeJoy. In the last decades, fatality numbers actually edged upward while the number of fires has gone down, he said.

On average, more than 100 firefighters die on the job in the U.S. each year, which is three times higher than the fatality rate for the general working population. The number one cause of death identified in the study was not smoke inhalation or traumatic injury, but cardiovascular events.

  • Eighty-seven of the 213 deaths examined in the study were cardiac-related.
  • Deaths from cardiovascular events resulted in two predominant recommendations from the researchers: the need for improvements in medical screening and the need for wider adoption of mandatory fitness/wellness programming.

Many of the recommendations can be traced to a lack of finances the report states. Not only does under-resourcing affect the ability of a fire department to acquire innovative technology, it can lead to a shortage of personnel at a fire, compromising rapid intervention and the ability to maintain command and control functions during operations, according to the authors.

The authors also acknowledged that there is a certain amount of subjective interpretation that goes into analyzing incident investigations. In addition, NIOSH investigations are not mandatory and can be refused by a fire department. NIOSH also mostly investigates deaths involving career, or paid, firefighters, although a majority of firefighters in the U.S. are volunteers and a majority of line-of-duty deaths involve volunteers. The authors further stated they hoped NIOSH will do more investigations of volunteer firefighter fatalities, as those organizations may have the greatest need for evaluation and technical assistance.

Technician I Kyle Wilson

Prince William County (VA) Fire Rescue Kyle Wilson LODD Report-Remembrance and Learnings

The Prince William County (VA) Department of Fire and Rescue published a comprehensive line of duty death report for Technician I Kyle R. Wilson on Saturday, January 26, 2008. Have your read it?

Technician I Wilson was the first line of duty death in the Department’s 41-year history. The Department shared the LODD Investigative Report to honor Kyle, and in an effort to reduce and prevent firefighter line of duty deaths at the local, region, state, and national levels.

Technician Kyle Robert Wilson was 24-years old and was born in Olney, Maryland. He grew up in Prince William County and graduated from Hylton High School and George Mason University. He was an avid baseball and softball player. Technician Wilson joined the Prince William County Department of Fire and Rescue on January 23, 2006.

  • Technician Kyle Wilson died in the line of duty on April 16, 2007 while performing search and rescue operations at a house fire on Marsh Overlook Drive, located in the Woodbridge area of Prince William County.

On that day, Technician Wilson was part of the firefighter staffing on Tower 512 which responded to the house fire that was dispatched at 0603 hours. The Prince William County area was under a high wind advisory as a nor’eastern storm moved through the area. Sustained winds of 25 mph with gusts up to 48 mph were prevalent in the area at the time of the fire dispatch to Marsh Overlook Drive.

  • Initial arriving units reported heavy fire on the exterior of two sides of the single family house and crews suspected that the occupants were still inside the house sleeping because of the early morning hour. A search of the upstairs bedroom commenced for the possible victims. A rapid and catastrophic change of fire and smoke conditions occurred in the interior of the house within minutes of Tower 512’s crew entering the structure.
  • Technician Wilson became trapped and was unable to locate an immediate exit out of the hostile environment. Mayday radio transmissions were made by crews and by Technician Kyle Wilson of the life-threatening situation. Valiant and repeated rescue attempts to locate and remove Technician Wilson were made by the firefighting crews during extreme fire, heat and smoke conditions. Firefighters were forced from the structure as the house began to collapse on them and intense fire, heat and smoke conditions developed. Technician Wilson succumbed to the fire and the cause of death was reported by the medical examiner to be thermal and inhalation injuries.

The Department of Fire and Rescue immediately formed a multi-dimensional investigation team following the incident. The investigation team was comprised of five Department of Fire and Rescue uniform personnel and two external members from area fire departments. For eight months, the team thoroughly examined the events that occurred at the Marsh Overlook fire incident and identify the factors involved with the line of duty death of Technician I Kyle Wilson. The resulting report represents thousands of hours of effort to analyze fire and rescue operations and is a factual representation of the events that occurred. The report also provides a frame work for organizational level improvements.

Time Line

  • The major factors in the line of duty death of Technician I Wilson were determined to be:
    • The initial arriving fire suppression force size.
    • The size up of fire development and spread.
    • The impact of high winds on fire development and spread.
    • The large structure size and lightweight construction and materials.
    • The rapid intervention and firefighter rescue efforts.
    • The incident control and management.
    • The Marsh Overlook fire incident was an immense fire fueled by extremely flammable building material products and a vicious wind. It was an environment where information gathering and decision making had to be performed in the time measurement of seconds. During the chain of events that occurred and under severe circumstances, fire and rescue personnel performed at exceptional levels.
  • During the repeated attempts to reach and rescue Technician I Wilson, personnel displayed heroic efforts and jeopardized their own safety.
  • The Department will never forget the sacrifice that Technician Wilson made in an attempt to ensure others were safe.
  • By sharing the knowledge gained from this very tragic and painful incident, the Department will ensure his sacrifice was not in vain and hope that other fire and rescue departments can avoid another similar occurrence.
  • It’s up to you to learn from this event and determine if there are lessons that can be applied to your organization and operations.

Overview

 

Incident

 

The Predictability of Performance; It's Occupany Risk not Occupancy Type

 

Today’s incident demands on the fireground are unlike those of the recent past, requiring incident commanders and commanding officers to have increased technical knowledge of building construction with a heightened sensitivity to fire behavior, a focus on operational structural stability and considerations related to occupancy risk versus the occupancy type.

There is an immediate need for today’s emerging and operating command and company officers to increase their foundation of knowledge and insights related to the modern building occupancy, building construction and fire protection engineering and to adjust and modify traditional and conventional strategic operating profiles in order to safeguard companies, personnel and team compositions.

Strategies and tactics must be based on occupancy risk, not occupancy type, and must have the combined adequacy of sufficient staffing, fire flow and tactical patience orchestrated in a manner that identifies with the fire profiling, predictability of the occupancy profile and accounts for presumptive fire behavior.

The dramatic changes in buildings and occupancies over the past ten years have resulted inadequate fire suppression methodologies based upon conventional practices that do not align with the manner in which we used to discern with a measured degree of predictability how buildings would perform, react and fail under most fire conditions.

We predicate certain expectations that fire will travel in a defined (predictable) manner that fire will hold within a room and compartment for a predictable given duration of time; that the fire load and related fire flows required will be appropriate for an expected size and severity of fire encountered within a given building, occupancy, structural system and given an appropriately trained and skilled staff to perform the requisite evolutions, we can safely and effectively mitigate a structural fire situation in any  given building type and occupancy.

Past operational experiences, both favorable and negative; gave us experiences that define and determine how the fireground is assessed, react and how we expect similar structures and occupancies to perform at a given alarm in the future; this formed the basis for the naturalistic decision-making process.

Implementing fundamentals of firefighting operations built upon nine decades of time-tested and experience-proven strategies and tactics continues to be the model of suppression operations. These same fundamental strategies continue to drive methodologies and curriculums in our current training programs and academies of instructions.

Are you aware of the defining changes in structural systems and support, the degree of compartmentation, the characteristics of materials and the magnitude of the fire-loading package in today’s buildings and occupancies? When was the last time you were out in the street with the companies, or spent some time doing a walk-through of construction or renovations site? Have you asked you commanding officers, division or battalion chief or your company officers for insights into what operational demands and risks are being imposed upon them while operating in the street and within the buildings, occupancies and structures that comprise your jurisdiction?

The structural anatomy, predictability of building performance under fire conditions, structural integrity and the extreme fire behavior; accelerated growth rate and intensively levels typically encountered in buildings of modern construction during initial and sustained fire suppression have given new meaning to the term combat fire engagement.

The rules for combat structural fire suppression have changed; but no one has told us. The IAFC Safety, Health & Survival Section (SH&S) spent that past year refining and updating The IAFC Ten Rules of Structural Fire Engagement. First published in 2001, the original Ten Rules of Engagement for Structural Fire Fighting provided a set of principles and parameters that incident commanders, commanding and company officers could utilize and implement during incident operations to decrease operations risk, increase and The Rules of Engagement for Firefighter Survival and The Incident Commanders Rules of Engagement for Firefighter Safety will provide a crucial link towards integrating occupancy risk considerations with more educated and informed understandings of buildings, occupancies, and the behavior of fire with a structure.

It’s no longer just brute force and sheer physical determination that define structural fire suppression operations, although any seasoned command and company officer knows that at times. It’s what gets the job done under the most arduous and demanding of circumstances.

However, from a methodical and disciplined perspective; aggressive firefighting must be redefined and aligned to the built environment and associated with goal-oriented tactical operations that are defined by risk assessed and analyzed strategic processes that are executed under battle plans that promote the best in safety practices and survivability within known hostile structural fire environments.

The demands and requirements of modern firefighting will continue to require the placement of personnel within situations and buildings that carry risk, uncertainty and inherent danger. As a result, risk management must become fluid and integrated with intelligent tactical deployments and operations recognizing the risk problematically and not fatalistically, resulting in safety conscious strategies and tactics.

Today’s incident commanders need to think about the Predicative Strategic Process, refined Tactical Deployment Models integrating intelligent Structural Anatomy and Predictive Occupancy Profiling, while implementing Tactical Patience.

Think about the following;

  • Read, comprehend and implement the new IAFC The Rules of Engagement for Firefighter Survival and The Incident Commanders Rules of Engagement for Firefighter Safety
  • Take a tour of your response area, district, community or city.
  • Take a good look around and begin to recognize the apparent or subtle changes that are affecting your incident operations; Take note and think about what needs to be adjusted, modified or changed in your operations.
  • Read up on the latest research and technical literature on wind driven fires, extreme fire behavior, structural ability of engineered lumber systems, fire loading and suppression theory
  • Take the time to personally read a series of the latest NIOSH Fire Fighter Fatality Investigation and Prevention Program LODD reports and relate them to your organizations operations and jurisdictional risks.
  • Start thinking in terms of Occupancy Risks versus Occupancy Type and align your operations and deployments to match those risks
  • Increase your situational awareness of today’s fireground and refine your strategic and tactical modeling
  • Implement both Strategic and Tactical Patience; Slow down and allow the building to react and stabilize, for fire behavior to stop behaving badly and for your companies to increase survivability ratios while meeting the demands of  conducting fire service operations
  • Reprogram your assumptions and presumptions and options on building construction and firefighting operations; the buildings have changed, our firefighting has not; what are you going to do about that gap?

Without understanding the building-occupancy relationships and integrating; construction, occupancies, fire dynamics and fire behavior, risk, analysis, the art and science of firefighting, safety conscious work environment concepts and effective and well-informed incident command management, company-level supervision and task-level competencies … You are derelict and negligent and “not “everyone may be going home”.

It’s all about understanding the building-occupancy relationships and the art and science of firefighting, equating to Building Knowledge = Firefighter Safety.

Charleston Sofa Super Store Fire; Final NIST Report Issued

1 comment

  

The National Institute of Standards and Technology (NIST) has released its final report on its study of the June 18, 2007, fire at the Sofa Super Store in Charleston, S.C., that trapped and killed nine firefighters, the highest number of firefighter deaths in a single event since 9/11. The final report was strengthened by clarifications and supplemental text based on comments provided by organizations and individuals in response to the draft report of the study, released for public comment on Oct. 28, 2010. (HERE) 

The revisions did not alter the study team’s main finding: the major factors contributing to the rapid spread of the fire at the Sofa Super Store were large open spaces with furniture providing high-fuel loads, the inward rush of air following the breaking of windows, and a lack of sprinklers. 

Based on its findings, the study team made 11 recommendations for enhancing building, occupant and firefighter safety nationwide. In particular, the team urged state and local communities to adopt and strictly adhere to current national model building and fire safety codes. These codes are used as models for building and fire regulations promulgated and enforced by U.S. state and local jurisdictions. Those jurisdictions have the option of incorporating some or all of the code’s provisions but often adopt most provisions. 

If today’s model codes had been in place and rigorously followed in Charleston in 2007, the study authors said, the conditions that led to the rapid fire spread in the Sofa Super Store probably would have been prevented. 

  • Specifically, the NIST report calls for national model building and fire codes to require sprinklers for all new commercial retail furniture stores regardless of size, and for existing retail furniture stores with any single display area of greater than 190 square meters (2,000 square feet).
  • Other recommendations include adopting model codes that cover high fuel load situations (such as a furniture store), ensuring proper fire inspections and building plan examinations, and encouraging research for a better understanding of fire situations such as venting of smoke from burning buildings and the spread of fire on furniture.
  • Two of the recommendations in the draft report were slightly modified to increase their effectiveness.
  • The recommendation “that all state and local jurisdictions ensure that fire inspectors and building plan examiners are professionally qualified to a national standard” was improved by listing three nationally accepted certification examinations as examples of “how professional qualification may be demonstrated.”
  • Another recommendation has been enhanced by urging state and local jurisdictions to “provide education to firefighters on the science of fire behavior in vented and non-vented structures and how the addition of air can impact the burning characteristics of the fuel.”

Based on their model and the data collected, the NIST researchers determined the following sequence of events on June 18, 2007, at the Sofa Super Store:

  • The fire began in trash outside the loading dock and spread into the enclosed loading dock. The fire spread from the exterior to the interior of the loading dock, which was used for staging furniture for delivery and repair. The fire spread quickly within the loading dock and moved into both the retail showroom and warehouse spaces.
  • During the early stages of this fire, the fire was unable to access enough air, a state that slowed its growth. However, the lack of sufficient air for complete combustion did result in large volumes of smoke and combustible gases flowing into the space below the roof and above the drop ceiling of the main retail showroom.
  • The fire spread to the rear of the main showroom through the holding area and ignited additional fuel in the rear of the main showroom, at which time it became more visible to firefighters in the main showroom.
  • The growth of the fire at the back of the main showroom was still slowed by the lack of air. As the fire burned in the rear of the main showroom, the fire pumped more hot unburned fuel into the smoke layer below the drop ceiling. The lack of air prevented the unburned fuel in the smoke layer from igniting.
  • When the front windows were broken (approximately 24 minutes after firefighters arrived at the store), additional air flowed in the front windows, along the floor and to the rear of the showroom, and became available to the fire. The additional air allowed the burning rate of the fire to increase rapidly and ignite the layer of unburned fuel below the drop ceiling.
  • The fire swept from the rear to the front of the main showroom extremely quickly, then into the west and east showrooms, trapping six firefighters in the main showroom and three firefighters in the west showroom.
  • Furniture and merchandise in the showrooms and warehouse continued to burn for an additional 140 minutes before the fire was extinguished.

NIST is working with various public and private groups toward implementing changes to practices, standards, and building and fire codes based on the findings from this study.

jurisdictions have the option of incorporating some or all of the code’s provisions but generally adopt most provisions. 


Recommendations from the NIST Study of the Charleston Sofa Super Store Fire

1. High Fuel-Load Mercantile Occupancies: NIST recommends that, at a minimum, all state and local jurisdictions adopt a building and fire code based upon one of the model codes, covering new and existing high fuel-load mercantile occupancies, and update local codes as the model codes are revised. 

2.   Model Code Adoption and Enforcement: NIST recommends that all state and local jurisdictions implement aggressive and effective fire inspection and enforcement programs that address: 

a) all aspects of the building and fire codes;
b) adequate documentation of building permits and alterations;
c) the means of inspecting fire protection systems and detailing record keeping;
d) the frequency and rigor of fire inspections, including follow-up and auditing procedures; and
e) guidelines for remedial requirements when inspections identify deviations from code provisions. 

3.  Qualified Fire Inspectors and Building Plan Examiners: NIST recommends that all state and local jurisdictions ensure that fire inspectors and building plan examiners are professionally qualified to a national standard such as National Fire Protection Association (NFPA) 1031. 

4.  Sprinklers: NIST recommends that model codes require sprinkler systems and that state and local authorities adopt and aggressively enforce this provision: 

a) for all new commercial retail furniture stores regardless of size; and
b) for existing retail furniture stores with any single display area of greater than 190 square meters (2,000 square feet). 

5.  Comprehensive Risk Management Plans:  NIST recommends that state and local jurisdictions use comprehensive risk management plans to: 

a) identify low, medium, and high hazard occupancies;
b) allocate resources according to risk identified; and
c) develop operating procedures that respond to specific risks. 

6.  Ventilation of Burning Structures: NIST recommends that state and local authorities:  

a) develop guidelines as to how and when ventilation should be implemented during a fire; and
b) provide training to fire fighters on different types of ventilation—vertical, horizontal and positive-pressure—and integrate into daily operations on the fire ground. 

7.  Research on Upholstered Furniture Flame Spread: NIST recommends that research be conducted to better understand ignition and fire spread on upholstered furniture in order to provide the tools needed by design professionals to improve the fire performance of furniture. The specific areas requiring research are: 

a) prediction of ignition of natural and synthetic coverings for current furniture, wall, ceiling and floor lining materials, and room furnishings;
b) prediction of fire spread over actual furniture with and without fire barriers, fire retardants and fire resistive materials; and
c) quantification of smoke and toxic gas production in realistic room fires. 

8.  Research on Improving Fire Barriers: NIST recommends that research be conducted to provide the tools needed by design professionals to improve the performance of compartmentalization. The specific areas requiring research are: 

a) prediction of fire spread through walls constructed of wood, metal and gypsum wallboard;
b) prediction of fire spread through doors constructed of glass, wood, and metal;
c) prediction of fire spread through penetrations; and
d) prediction of performance of roll-up fire doors in actual fires and after extended service.  

9.  Research on Decision Aids for Allocation of Resources: NIST recommends that research be conducted to: 

a) refine computer-aided decision tools for determining the costs and benefits of alternative code changes and fire safety technologies; and
b) develop computer models to assist communities in allocating resources (money and staff) to ensure that their response to an emergency with a large number of potential casualties is effective. 

10.  Research on Ventilation of Burning Structures: NIST recommends that additional research be conducted to: 

a) improve characterization of how ventilation affects the growth and spread of fire within structures; and
b) provide the fire service with guidance on when and how to use ventilation to improve the fire environment during fire service operations. 

11.  Research on Performance Metrics for Fire Protection: NIST recommends that research be conducted to: 

a) develop performance and effectiveness metrics for community fire protection;
b) survey effectiveness of existing fire services; and
c) use metrics to optimize development of new technologies.

UL Ventilation and Fire Behavior Full Scale Testing

Impact of Ventilation on Fire Behavior in Legacy and Contemporary Residential Construction

For many of you that have been following my writings and perspectives on building construction, firefighting, command risk management and operational excellence for firefighter safety have long recognized that I have been promoting and advocating the fact the fireground is changining, our stratgies and tactics demand change adn does the demand for increased knowledge within the areas of building construction, fire dynamics, while integrating the art and science of firefighting. The most recent release of the testing report from Underwriters Laboratories; Impact of Ventilation on Fire Behavior in Legacy and Contemporary Residential Construction and the accompaning emphirical data further validates assumptions and presmises that many of us shared based upon field obervations and first hand incident operations related to the dramatic changes being witnessed as a result of operational challenges in a wide varity of occupanies and building types. This material is a must read for all emerging and practicing company and command officers ( for starters) to being grasping the magnitude and extent of quantifiable data that supports the premise that combat fire engagement and suppression operations and the rules of engagement are going to change and that change is fast approaching. Considerations for Tactical Patience and Adaptive Fireground Management are continued themes I will expand upon in future postings….

Here’s the executive summary of the report and findings from UL. For an download of the entire UL Report, go HERE.

Under the United States Department of Homeland Security (DHS) Assistance to Firefighter Grant Program, Underwriters Laboratories examined fire service ventilation practices as well as the impact of changes in modern house geometries.  There has been a steady change in the residential fire environment over the past several decades.  These changes include larger homes, more open floor plans and volumes and increased synthetic fuel loads.  This series of experiments examine this change in fire behavior and the impact on firefighter ventilation tactics.  This fire research project developed the empirical data that is needed to quantify the fire behavior associated with these scenarios and result in immediately developing the necessary firefighting ventilation practices to reduce firefighter death and injury.

Two houses were constructed in the large fire facility of Underwriters Laboratories in Northbrook, IL.  The first of two houses constructed was a one-story, 1200 ft2, 3 bedroom, 1 bathroom house with 8 total rooms.  The second house was a two-story 3200 ft2, 4 bedroom, 2.5 bathroom house with 12 total rooms.  The second house featured a modern open floor plan, two-story great room and open foyer.   Fifteen experiments were conducted varying the ventilation locations and the number of ventilation openings.  Ventilation scenarios included ventilating the front door only, opening the front door and a window near and remote from the seat of the fire, opening a window only and ventilating a higher opening in the two-story house.  One scenario in each house was conducted in triplicate to examine repeatability.

The results of these experiments provide knowledge for the fire service for them to examine their thought processes, standard operating procedures and training content.  Several tactical considerations were developed utilizing the data from the experiments to provide specific examples of changes that can be adopted based on a departments current strategies and tactics.

There has been a steady change in the residential fire environment over the past several decades. These changes include larger homes, more open floor plans and volumes and increased synthetic fuel loads. This series of experiments examine this change in fire behavior and the impact on firefighter ventilation tactics.

This fire research project developed the empirical data that is needed to quantify the fire behavior associated with these scenarios and result in immediately developing the necessary firefighting ventilation practices to reduce firefighter death and injury.

  • Two houses were constructed in the large fire facility of Underwriters Laboratories in Northbrook, IL.
  • The first of two houses constructed was a one-story, 1200 ft2, 3 bedroom, 1 bathroom house with 8 total rooms.
  • The second house was a two-story 3200 ft2, 4 bedroom, and 2.5 bathroom house with 12 total rooms.
  • The second house featured a modern open floor plan, two story great room and open foyer.

Fifteen experiments were conducted varying the ventilation locations and the number of ventilation openings. Ventilation scenarios included ventilating the front door only, opening the front door and a window near and remote from the seat of the fire, opening a window only and ventilating a higher opening in the two-story house.

One scenario in each house was conducted in triplicate to examine repeatability. The results of these experiments provide knowledge for the fire service for them to examine their thought processes, standard operating procedures and training content. Several tactical considerations were developed utilizing the data from the experiments to provide specific examples of changes that can be adopted based on a departments current strategies and tactics.

The tactical considerations addressed include:

  • Stages of fire development: The stages of fire development change when a fire becomes ventilation limited.
    • It is common with today’s fire environment to have a decay period prior to flashover which emphasizes the importance of ventilation.
  • Forcing the front door is ventilation: Forcing entry has to be thought of as ventilation as well.
    • While forcing entry is necessary to fight the fire it must also trigger the thought that air is being fed to the fire and the clock is ticking before either the fire gets extinguished or it grows until an untenable condition exists jeopardizing the safety of everyone in the structure.
  • No smoke showing: A common event during the experiments was that once the fire became ventilation limited the smoke being forced out of the gaps of the houses greatly diminished or stopped all together.
    • No some showing during size-up should increase awareness of the potential conditions inside.
  • Coordination: If you add air to the fire and don’t apply water in the appropriate time frame the fire gets larger and safety decreases.
    • Examining the times to untenability gives the best case scenario of how coordinated the attack needs to be.
    • Taking the average time for every experiment from the time of ventilation to the time of the onset of firefighter untenability conditions yields 100 seconds for the one-story house and 200 seconds for the two-story house
    • In many of the experiments from the onset of firefighter untenability until flashover was less than 10 seconds.
    • These times should be treated as being very conservative. If a vent location already exists because the homeowner left a window or door open then the fire is going to respond faster to additional ventilation opening because the temperatures in the house are going to be higher.
    • Coordination of fire attack crew is essential for a positive outcome in today’s fire environment.
  • Smoke tunneling and rapid air movement through the front door: Once the front door is opened attention should be given to the flow through the front door.
    • A rapid in rush of air or a tunneling effect could indicate a ventilation limited fire.
  • Vent Enter Search (VES): During a VES operation, primary importance should be given to closing the door to the room.
    • This eliminates the impact of the open vent and increases tenability for potential occupants and firefighters while the smoke ventilates from the now isolated room.
  • Flow paths: Every new ventilation opening provides a new flow path to the fire and vice versa.
    • This could create very dangerous conditions when there is a ventilation limited fire.
  • Can you vent enough?: In the experiments where multiple ventilation locations were made it was not possible to create fuel limited fires.
    • The fire responded to all the additional air provided.
    • That means that even with a ventilation location open the fire is still ventilation limited and will respond just as fast or faster to any additional air.
    • It is more likely that the fire will respond faster because the already open ventilation location is allowing the fire to maintain a higher temperature than if everything was closed. In these cases rapid fire progression if highly probable and coordination of fire attack with ventilation is paramount.
  • Impact of shut door on occupant tenability and firefighter tenability: Conditions in every experiment for the closed bedroom remained tenable for temperature and oxygen concentration thresholds.
    • This means that the act of closing a door between the occupant and the fire or a firefighter and the fire can increase the chance of survivability.
    • During firefighter operations if a firefighter is searching ahead of a hoseline or becomes separated from his crew and conditions deteriorate then a good choice of actions would be to get in a room with a closed door until the fire is knocked down or escape out of the room’s window with more time provided by the closed door
  • Potential impact of open vent already on flashover time: All of these experiments were designed to examine the first ventilation actions by an arriving crew when there are no ventilation openings.
    • It is possible that the fire will fail a window prior to fire department arrival or that a door or window was left open by the occupant while exiting.
    • It is important to understand that an already open ventilation location is providing air to the fire, allowing it to sustain or grow.
  • Pushing fire: There were no temperature spikes in any of the rooms, especially the rooms adjacent to the fire room when water was applied from the outside. It appears that in most cases the fire was slowed down by the water application and that external water application had no negative impacts to occupant survivability.
    • While the fog stream “pushed” steam along the flow path there was no fire “pushed”.
  • No damage to surrounding rooms: Just as the fire triangle depicts, fire needs oxygen to burn.
    • A condition that existed in every experiment was that the fire (living room or family room) grew until oxygen was reduced below levels to sustain it.
    • This means that it decreased the oxygen in the entire house by lowering the oxygen in surrounding rooms and the more remote bedrooms until combustion was not possible.
    • In most cases surrounding rooms such as the dining room and kitchen had no fire in them even when the fire room was fully involved in flames and was ventilating out of the structure.

Comparison of Modern and Legacy Home Furnishings

An experiment was conducted with two side by side living room fires.   The purpose was to gain knowledge on the difference between modern and legacy furnishings.  The rooms measured 12 ft by 12 ft, with an 8 ft ceiling and had an 8 ft wide by 7 ft tall opening on the front wall.  Both rooms contained similar amounts of like furnishings.

The modern room was lined with a layer of ½ inch painted gypsum board and the floor was covered with carpet and padding.

  • The furnishings included a microfiber covered polyurethane foam filled sectional sofa, engineered wood coffee table, end table, television stand and book case.
  • The sofa had a polyester throw placed on its right side.  The end table had a lamp with polyester shade on top of it and a wicker basket inside it.
  • The coffee table had six color magazines, a television remote and a synthetic plant on it.
  • The television stand had a color magazine and a 37 inch flat panel television.
  • The book case had two small plastic bins, two picture frames and two glass vases on it.
  • The right rear corner of the room had a plastic toy bin, a plastic toy tub and four stuffed toys.
  • The rear wall had polyester curtains hanging from a metal rod and the side walls had wood framed pictures hung on them.

The legacy room was lined with a layer of ½ inch painted cement board and the floor was covered with unfinished hardwood flooring.

  • The furnishings included a cotton covered, cotton batting filled sectional sofa, solid wood coffee table, two end tables, and television stand.
  • The sofa had a cotton throw placed on its right side.
  • Both end tables had a lamp with polyester shade on top of them.
  • The one on the left side of the sofa had two paperback books on it.
  • A wicker basket was located on the floor in front of the right side of the sofa at the floor level.
  • The coffee table had three hard-covered books, a television remote and a synthetic plant on it.
  • The television stand had a 27 inch tube television.
  • The right front corner of the room had a wood toy bin, and multiple wood toys.
  • The rear wall had cotton curtains hanging from a metal rod and the side walls had wood framed pictures hung on them.

Both rooms were ignited by placing a lit stick candle on the right side of the sofa.  The fires were allowed to grow until flashover.  The modern room transitioned to flashover in 3 minutes and 30 seconds and the legacy room at 29 minutes and 30 seconds.

Worcester Cold Storage Warehouse Fire 1999

3 comments

Today December 3, 2010 marks the 11th anniversary of the Worcester Cold Storage Warehouse fire that resulted in the line of duty death of six courages brother firefighters.   

For those of you who remember this event, take the time to reflect and honor the sacrifice made this day; to those of you who have not heard about the fire before- take the time to learn about the incident, the firefighters, the building, the operational factors and challenges, the courage, fortitude and convictions that define the American Fire Service, it’s honor, tradition and brotherhood.   

The Worcester Six;   

  • Firefighter Paul Brotherton Rescue 1
  • Firefighter Jeremiah Lucey Rescue 1
  • Lieutenant Thomas Spencer Ladder 2
  • Firefighter Timothy Jackson Ladder 2
  • Firefighter James Lyons Engine 3
  • Firefighter Joseph McGuirk Engine

   

On Friday, December 3, 1999, at 1813 hours, the Worcester, Massachusetts Fire Department dispatched Box 1438 for 266 Franklin Street, the Worcester Cold Storage and Warehouse Co. A motorist had spotted smoke coming from the roof while driving on an adjacent elevated highway. The original building was constructed in 1906, contained another 43,000 square feet. Both were 6 stories above grade. The building was known to be abandoned for over 10 years.   

Due to these and other factors, the responding District Chief ordered a second alarm within 4 minutes of the initial dispatch. The first alarm assignment brought 30 firefighters and officers and 7 pieces of apparatus to the scene. The second provided an additional 12 men and 3 trucks as well as a Deputy Chief. Firefighters encountered a light smoke condition throughout the warehouse, and crews found a large fire in the former office area of the second floor. An aggressive interior attack was started within the second floor and ventilation was conducted on the roof. There were no windows or other openings in the warehousing space above the second floor.   

Eleven minutes into the fire, the owner of the abutting Kenmore Diner advised fire operations of two homeless people who might be living in the warehouse. The rescue company, having divided into two crews, started a building search. Some 22 minutes later the rescue crew searching down from the roof became lost in the vast dark spaces of the fifth floor. They were running low on air and called for help. Interior conditions were deteriorating rapidly despite efforts to extinguish the blaze, and visibility was nearly lost on the upper floors. Investigators have placed these two firefighters over 150 feet from the only available exit.

An extensive search was conducted by Worcester Fire crews through the third and fourth alarms. Suppression efforts continued to be ineffective against huge volumes of petroleum based materials, and ultimately two more crews became disoriented on the upper floors and were unable to escape. When the evacuation order was given one hour and forty-five minutes into the event, five firefighters and one officer were missing. None survived.   

A subsequent exterior attack was set up and lasted for over 20 hours utilizing aerial pieces and deluge guns from Worcester and neighboring departments. Task force groups from across the State of Massachusetts responded to initial suppression and subsequent recovery efforts. During this time, the four upper floors collapsed onto the second which became known as “the deck”. Over 6 million gallons of water were used during the suppression efforts.   

According to NFPA records, this is the first loss of six firefighters in a structure fire where neither building collapse nor an explosion was a contributing factor to the fatalities.     

 

Fireground Operations

    

KEY ISSUES   

Abandoned building left unprotected and unsecured.   

  • The failure to properly secure and maintain security at this warehouse allowed vagrants to enter, live in, and cause a fire in the building.
  • The lack of detection and suppression systems allowed the fire to grow unrestrained until discovered from the outside.

No barriers to prevent the spread of fire and smoke in a large space.   

  • Despite some floors having over 15,000 square feet of storage space, there were no rated fire walls, functioning fire doors, or even an interior finish that would help limit fire growth and the spread of heat and smoke.

Fire spread via combustible interior finishes.   

  • Being a cold storage warehouse, many walls and ceilings were covered with a combustible insulation material including cork, tar, expanded polystyrene foam, and sprayed-on polyurethane foam.

Delayed fire reporting   

  • The building occupants left the warehouse without notifying authorities, and the fire was reported by passing motorists who observed smoke venting from the roof.
  • The absence of uncovered windows also prevented earlier detection from the exterior.

Access limitations for fire suppression and rescue.   

  • Building construction featured a single staircase from the basement to the roof. This vertical opening was the only way to move through all levels and was congested with men and equipment from the start of operations.
  • The storage areas of the warehouse had no windows. These two factors left firefighters above the first floor without a secondary escape route and prevented ladder and rescue operations through windows.

Unusually long interior travel distances.   

  • Firefighters had to crawl over 200 feet through heavy smoke from the single staircase to conduct a proper search.
  • Most lifelines were only 50 foot and SCBA air was limited to 30 minutes.
  • Searches and rescue operations were ineffective under these circumstances.

    

Exterior Circa 1998

BUILDING HISTORY AND CONSTRUCTION   

The Worcester Cold Storage and Warehouse building was a six story structure at 266 Franklin Street in the heart of Worcester’s former warehousing and cold storage district. In the first half of the 21st century, cold storage was vital to the preservation and delivery of food before refrigerators became commonplace in American kitchens. The location was ideal with rail service provided by the former Boston and Albany Railroad which had a siding against the south end of the warehouse.   

Even after the post-WWII decline in railroads, truck traffic was easily accommodated over nearby roads and later on the abutting Interstate 290 which was built in the late 1960’s.   

The original warehouse (called “A-building” in previous reports) was constructed in 1906, faced due north onto Franklin Street and bordered Arctic Street to the east. There were six storage levels as well as a basement. The building measured 88 feet by 88 feet and had over 7,000 square feet of floor space on each level. The warehouse had an approximate exterior height of 80 feet.   

An addition (called “B-building”) was constructed in 1912 against the west wall of A-building and measured 72 feet by 120 feet on the third floor and above. The 72 foot wall faced Franklin Street. The first and second floors were 88 foot and 101 foot deep respectively to accommodate railroad sidings and other structures on the southern on “C” side. Other investigations have referred to the former western exterior wall of A-building as “the fire wall” but there is no indication that this was a planned function. At least one opening was cut through this party wall on each level to access the new addition. B-building provided an additional 7,000 square feet of storage on the third floor and over 8,000 on floors four through six.   

The Worcester Cold Storage complex involved additional structures to the south, but these were physically separate buildings and were not involved in this incident. The known openings between the warehouse and the southern structures were for utilities and refrigerants. The only effect was to block aerial access from the south during the fire.   

  • Construction methods appear to be the same in both A and B buildings.
  • Exterior walls were 18 inches thick and consisted of brick and mortar. Interior floors on the first and second levels were poured concrete and were supported by cast iron columns.
  • The concrete was covered with carpet or asbestos tile where appropriate for use.
  • Upper floors were of heavy timber construction with 12 foot long 4 inch by 12 inch wood joists (16 inch o.c.) resting in pockets in the east and west brick exterior walls and attached to 16 inch by 16 inch wood girders on the inside.
  • The girders were on 12 foot centers and rested on 16 inch by 16 inch wood columns which were spaced 12 feet apart in both dimensions.
  • Flooring consisted of two layers of tongue and groove hardwood with some areas having an additional layer of 3/8 inch diamond plate.
  • Ceilings on individual floors varied from open joists in storage areas to be a suspended ceiling in the office area on the second floor.
  • Photographs taken prior to the fire suggest that some sections also had “glass board” as a finished surface. The exact make up of this material has not been determined.
  • No documentation was made of ceiling heights within the warehouse, but it appears they were approximately 11 foot throughout.
  • The roof was tar and gravel over a wood deck which covered a 4 foot tall cockloft above the sixth floor ceiling/roof assembly.
  • Roof penetrations included the stairway and elevator shaft on the east end of A-building and a skylight over the elevator shafts on B-building. An illuminated billboard sat on the roof of B-building and received power external to the warehouse structure.

NOTE: For the balance of this report the entire fire building will be referred to as the “warehouse” which consists of “A-building” on the east and “B-building” on the west. The A and B terminology was adopted early on in other investigations and should not be confused with fireground identifications of sides “A, B, C, & D”. In a large complex such as this, other terminology could have been created such as “Building 1”, “Building Z”, etc. (refer to the USFA Report for diagrams)   

BUILDING USE   

Worcester Cold Storage, a business, occupied the warehouse from 1906 until 1983 when it was sold to Chicago Dressed Beef. In 1987, CDB Realty Trust purchased the warehouse. CDB moved its operations to Millbrook Street in 1988 and shut down the refrigeration system in 1989 at which time the building was abandoned.   

During its use, various petroleum based insulation materials were incorporated into the building including rigid expanded polystyrene boards and blown on polyurethane foam. These were applied to improve the temperature performance of the buildings Additionally, condensation along the exterior walls lead to the decay of some floor joists. Steel beams or angle brackets were added against the brick walls to pick up the floor load in several places.   

  • Even to long term employees, the building was hard to navigate.
  • The upper four stories were almost identical, and some workers reported getting lost under the dim interior lighting conditions.
  • Condensation would cause ice to form around the ceiling fixtures, and this cone of ice would severely limit the amount of illumination.
  • There was no useful external light then or during the fire.

After it’s closing in 1989, the building was illegally entered on many occasions, resulting in vandalism, occupancy by homeless individuals, and a number of small “campfires.” At the time the fire occurred, there were no utility services in operation. Significant amounts of garbage and human wastes were scattered around the warehouse. The homeless woman involved in this incident said the interior smelled like a sewer.   

VERTICAL PENETRATIONS   

There were three stairways in the warehouse. Stairway 1 was in the northwest corner of B-building and went from the first floor (approximate street level) up to the second floor office area. Stairway 2 was located in the southern portion of B-building and went from the first floor to the third. It may have also accessed the basement. Stairway 3 was on the east side of A-building and ran from the basement to the roof. This was the only means of egress from the upper floors and was used heavily during the fire.   

Two elevators were adjacent to stairway 3, and two more were adjacent to Stairway 2. At the time of the fire, all had been disabled, and the cars were in the basement. It is unknown if individual access doors were open or closed. The elevator shaft in B-building had a reinforced glass canopy at the roof level.   

  • A 14 inch by 14 inch shaft penetrated the ceiling of the second floor office area and originally housed a 12 inch pipe for the ammonia recovery system.
  • This may have opened through all floors, and the presence of the pipe could not be confirmed.

HORIZONTAL PENETRATIONS   

There was one opening on each level through the party wall dividing A-building from B-building. There were numerous doors and windows on the first floor, and several were forced open by firefighters to gain access. All windows on this level were secured with plywood to prevent entry. Windows on the second floor of B-building were limited to the office area in the northwest section and were also covered with plywood. There was a window on each of the second, third, and fourth floors in stairway 3 on the east side of A-building. A window opened into the adjacent elevator shaft on each of these floors also. All were blocked with plywood.   

INTERIOR FINISH   

Because the warehouse was used for cold storage, the insides of exterior walls and the roof were heavily insulated. Barriers between office space and freezer space were also heavily insulated. The original material of choice was cork which was impregnated or secured with tar. The thickness has been described from 6 inches to 18 inches depending on the location. Evidence was also found of additional layers of expanded polystyrene sheets and blown on polyurethane. In many places the finished surface was “glass board”. A recovered piece of this glass board was ignited by Worcester Fire personnel after this incident. The sample sustained combustion and gave off stringy black smoke not unlike pure styrene.   

It was reported that all the interior partitions were made of corkboard, but it was probably a covering rather than a structural element. The office walls on the second floor were paneling installed over drywall. Many photographs of the cold storage areas taken before the fire show interior surfaces with a clean outer appearance consistent with the glass board. This would have provided a cleanable and wear resistant surface as opposed to bare cork or foam insulation.   

INTERIOR LAYOUT   

Since the fire did not extend to the basement or first floor, the layout of these spaces is less important. The first floor did, however, provide the access to the rest of the building for fire operations. All space above the first floor was used for cold storage or moving goods with the exception of the second floor office area on the northern half of B-building.

Occupancy Risks versus Occupancy Types

3 comments

The Predictability of Performance; It's Occupany Risk not Occupancy Type

Today’s incident demands on the fireground are unlike those of the recent past, requiring incident commanders and commanding officers to have increased technical knowledge of building construction with a heightened sensitivity to fire behavior, a focus on operational structural stability and considerations related to occupancy risk versus the occupancy type.

There is an immediate need for today’s emerging and operating command and company officers to increase their foundation of knowledge and insights related to the modern building occupancy, building construction and fire protection engineering and to adjust and modify traditional and conventional strategic operating profiles in order to safeguard companies, personnel and team compositions.

Strategies and tactics must be based on occupancy risk, not occupancy type, and must have the combined adequacy of sufficient staffing, fire flow and tactical patience orchestrated in a manner that identifies with the fire profiling, predictability of the occupancy profile and accounts for presumptive fire behavior.

The dramatic changes in buildings and occupancies over the past ten years have resulted inadequate fire suppression methodologies based upon conventional practices that do not align with the manner in which we used to discern with a measured degree of predictability how buildings would perform, react and fail under most fire conditions.

We predicate certain expectations that fire will travel in a defined (predictable) manner that fire will hold within a room and compartment for a predictable given duration of time; that the fire load and related fire flows required will be appropriate for an expected size and severity of fire encountered within a given building, occupancy, structural system and given an appropriately trained and skilled staff to perform the requisite evolutions, we can safely and effectively mitigate a structural fire situation in any  given building type and occupancy.

Past operational experiences, both favorable and negative; gave us experiences that define and determine how the fireground is assessed, react and how we expect similar structures and occupancies to perform at a given alarm in the future; this formed the basis for the naturalistic decision-making process.

Implementing fundamentals of firefighting operations built upon nine decades of time-tested and experience-proven strategies and tactics continues to be the model of suppression operations. These same fundamental strategies continue to drive methodologies and curriculums in our current training programs and academies of instructions.

Are you aware of the defining changes in structural systems and support, the degree of compartmentation, the characteristics of materials and the magnitude of the fire-loading package in today’s buildings and occupancies? When was the last time you were out in the street with the companies, or spent some time doing a walk-through of construction or renovations site? Have you asked you commanding officers, division or battalion chief or your company officers for insights into what operational demands and risks are being imposed upon them while operating in the street and within the buildings, occupancies and structures that comprise your jurisdiction?

The structural anatomy, predictability of building performance under fire conditions, structural integrity and the extreme fire behavior; accelerated growth rate and intensively levels typically encountered in buildings of modern construction during initial and sustained fire suppression have given new meaning to the term combat fire engagement.

The rules for combat structural fire suppression have changed; but no one has told us. The IAFC Safety, Health & Survival Section (SH&S) spent that past year refining and updating The IAFC Ten Rules of Structural Fire Engagement. First published in 2001, the original Ten Rules of Engagement for Structural Fire Fighting provided a set of principles and parameters that incident commanders, commanding and company officers could utilize and implement during incident operations to decrease operations risk, increase and amplify personnel safety of operating companies.

The section moved to develop rules of engagement for structural firefighting to serve as nationally developed model procedures (SOPs) offered by the IAFC. These new Rules of Engagement for Structural Fire Fighting have been posted on the IAFC SH&S web page and were officially rolled out the Fire Rescue International in Chicago in 2010.

The Rules of Engagement for Firefighter Survival and The Incident Commanders Rules of Engagement for Firefighter Safety will provide a crucial link towards integrating occupancy risk considerations with more educated and informed understandings of buildings, occupancies, and the behavior of fire with a structure.

It’s no longer just brute force and sheer physical determination that define structural fire suppression operations, although any seasoned command and company officer knows that at times. It’s what gets the job done under the most arduous and demanding of circumstances.

However, from a methodical and disciplined perspective; aggressive firefighting must be redefined and aligned to the built environment and associated with goal-oriented tactical operations that are defined by risk assessed and analyzed strategic processes that are executed under battle plans that promote the best in safety practices and survivability within known hostile structural fire environments.

The demands and requirements of modern firefighting will continue to require the placement of personnel within situations and buildings that carry risk, uncertainty and inherent danger. As a result, risk management must become fluid and integrated with intelligent tactical deployments and operations recognizing the risk problematically and not fatalistically, resulting in safety conscious strategies and tactics.

Today’s incident commanders need to think about the Predicative Strategic Process, refined Tactical Deployment Models integrating intelligent Structural Anatomy and Predictive Occupancy Profiling, while implementing Tactical Patience.

Think about the following;

  • Read, comprehend and implement the new IAFC The Rules of Engagement for Firefighter Survival and The Incident Commanders Rules of Engagement for Firefighter Safety
  • Take a tour of your response area, district, community or city.
  • Take a good look around and begin to recognize the apparent or subtle changes that are affecting your incident operations; Take note and think about what needs to be adjusted, modified or changed in your operations.
  • Read up on the latest research and technical literature on wind driven fires, extreme fire behavior, structural ability of engineered lumber systems, fire loading and suppression theory
  • Take the time to personally read a series of the latest NIOSH Fire Fighter Fatality Investigation and Prevention Program LODD reports and relate them to your organizations operations and jurisdictional risks.
  • Start thinking in terms of Occupancy Risks versus Occupancy Type and align your operations and deployments to match those risks
  • Increase your situational awareness of today’s fireground and refine your strategic and tactical modeling
  • Implement both Strategic and Tactical Patience; Slow down and allow the building to react and stabilize, for fire behavior to stop behaving badly and for your companies to increase survivability ratios while meeting the demands of  conducting fire service operations
  • Reprogram your assumptions and presumptions and options on building construction and firefighting operations; the buildings have changed, our firefighting has not; what are you going todo about that gap?

If you don’t fully understand how a building truly performs or reacts under fire conditions and the variables that can influence its stability and degradation, movement of fire and products of combustion and the resource requirements for fire suppression in terms of staffing, apparatus and required fire flows, then you will be functioning and operating in a reactionary manner that is no longer acceptable within many of our modern building types, occupancies and structures. This places higher risk to your personnel and lessens the likelihood for effective, efficient and safe operations. You’re just not doing your job effectively and you’re at risk. These risks can equate into insurmountable operational challenges and could lead to adverse incident outcomes. Someone could get hurt, someone could die, it’s that simple; it’s that obvious.

Without understanding the building-occupancy relationships and integrating; construction, occupancies, fire dynamics and fire behavior, risk, analysis, the art and science of firefighting, safety conscious work environment concepts and effective and well-informed incident command management, company-level supervision and task-level competencies … You are derelict and negligent and “not “everyone may be going home”.

It’s all about understanding the building-occupancy relationships and the art and science of firefighting, equating to Building Knowledge = Firefighter Safety.

Taking it to the Streets with Christopher Naum

Wednesday Night’s Program has been postponed due to Emergent Server issues at BlogTalkRadio.

The Program has been rescheduled for Thursday November 4th at 9:00pm EDT

Turn Out to FireFighter NetCast.com and Taking it to the Streets for; “Redefining the Fire Ground”

If you missed last month’s program on the Tactical Renaissance of Combat Fire Suppression Operations and the new Rules of Engagement, with Chief Gary Morris (ret) Phoenix (AZ) Fire Department and Dr. Burt Clark from the NFA, then you missed out a some great insights and discussion. This month Taking it to the Streets is looking to further the dialog and look at “Redefining the Fire Ground”. Many would argue that the fire ground doesn’t need to be “redefined”; that the way we do business in the Streets is just fine and that the American Fire Service knows how to get the job done, at any cost.

The recent release of the NIST Technical Study of the Sofa Super Store Fire – South Carolina, June 18, 2007 has presented compelling data and information that provides further discernments of how our buildings react under fire conditions and how our tactical assumptions and deployments continue to be willfully miscued.  Joining Chris will be Chief Douglas Cline, from the City of High Point FD, North Carolina, a highly regarded national instructor, author, advocate, tactician and incident command.

Don’t miss out on debating and dialoging the transitional fire ground. It is here and it’s here to stay; you just didn’t know that it was changing.

NIST Study on Charleston Furniture Store Fire Calls for National Safety Improvements

1 comment

Major factors contributing to a rapid spread of fire at the Sofa Super Store in Charleston, S.C., on June 18, 2007, included large open spaces with furniture providing high fuel loads, the inward rush of air following the breaking of windows and a lack of sprinklers, according to a draft report released for public comment today by the U.S. Commerce Department’s National Institute of Standards and Technology (NIST). The fire trapped and killed nine firefighters, the highest number of firefighter fatalities in a single event since 9/11.

Based on its findings, the NIST technical study team made 11 recommendations for enhancing building, occupant and firefighter safety nationwide. In particular, the team urged state and local communities to adopt and strictly adhere to current national model building and fire safety codes.1 If today’s model codes had been in place and rigorously followed in Charleston in 2007, the study authors said, the conditions that led to the rapid fire spread in the Sofa Super Store probably would have been prevented.

“Furniture stores typically have large amounts of combustible material and represent a significant fire hazard,” said NIST study leader Nelson Bryner. “Model building codes should require both new and existing furniture stores to have automatic sprinklers, especially if those stores include large, open display areas.”

Specifically, the NIST report calls for national model building and fire codes to require sprinklers for all new commercial retail furniture stores regardless of size, and for existing retail furniture stores with any single display area of greater than 190 square meters (2,000 square feet). Other recommendations include adopting model codes that cover high fuel load situations (such as a furniture store), ensuring proper fire inspections and building plan examinations, and encouraging research for a better understanding of fire situations such as venting of smoke from burning buildings and the spread of fire on furniture.

Using a state-of-the-art computer model to simulate the fire, the study team found that the addition of automatic sprinklers inside the loading dock could have significantly slowed the fire (which began just outside the dock area), prevented it from spreading beyond the dock, and eventually, extinguished it completely. The model also showed that sprinklers on the loading dock likely would have maintained what firefighters call tenability conditions, the ability for individuals in a fire event to escape unassisted.

Factors identified as contributing to the fire’s progress include: (1) the high fuel loads—especially furniture—present throughout the building; (2) the lack of sprinklers throughout the Sofa Super Store; (3) the open floor plan of the facility; (4) the hidden build-up of combustible smoke and gases in the area between the drop ceiling and the roof of the main showroom; (5) the non-fire-activated roll-up door that was open between the loading dock and the holding area; (6) the four fire-activated roll-up doors (out of seven) that activated but did not close during the fire; (7) the metal walls in the warehouse and west showroom that allowed heat from the fire to ignite items next to the walls; and (8) the breaking of windows at the front of the store that supplied air to the fire.

NIST’s team of experts traveled to Charleston to gather data within 36 hours of the Sofa Super Store fire. Using these data and other information collected in the following months (such as building design documents, records, plans, video and photographic data, radio transmissions, interviews with emergency responders, and informal discussions with store employees), the NIST study team developed its computer model to simulate and analyze the characteristics of the fire, including fire spread, smoke movement, tenability, and the operation of active and passive fire protection systems.

Based on their model and the data collected, the NIST researchers determined the following sequence of events on June 18, 2007, at the Sofa Super Store:

  • The fire began in trash outside the loading dock and spread into the enclosed loading dock. The fire spread from the exterior to the interior of the loading dock, which was used for staging furniture for delivery and repair. The fire spread quickly within the loading dock and moved into both the retail showroom and warehouse spaces.
  • During the early stages of this fire, the fire was unable to access enough air, a state that slowed its growth. However, the lack of sufficient air for complete combustion did result in large volumes of smoke and combustible gases flowing into the space below the roof and above the drop ceiling of the main retail showroom.
  • The fire spread to the rear of the main showroom through the holding area and ignited additional fuel in the rear of the main showroom, at which time it became more visible to firefighters in the main showroom.
  • The growth of the fire at the back of the main showroom was still slowed by the lack of air. As the fire burned in the rear of the main showroom, the fire pumped more hot unburned fuel into the smoke layer below the drop ceiling. The lack of air prevented the unburned fuel in the smoke layer from igniting.
  • When the front windows were broken (approximately 24 minutes after firefighters arrived at the store), additional air flowed in the front windows, along the floor and to the rear of the showroom, and became available to the fire. The additional air allowed the burning rate of the fire to increase rapidly and ignite the layer of unburned fuel below the drop ceiling.
  • The fire swept from the rear to the front of the main showroom extremely quickly, then into the west and east showrooms, trapping six firefighters in the main showroom and three firefighters in the west showroom.
  • Furniture and merchandise in the showrooms and warehouse continued to burn for an additional 140 minutes before the fire was extinguished.

The complete draft report is available online at http://www.nist/gov/el

NIST welcomes comments on the draft report and its recommendations. To be considered for the final report, comments must be received by noon EST on Dec. 2, 2010. Comments may be submitted via e-mail to firesafety@nist.gov; fax to (301) 975-4052; or mail to the attention of NIST Technical Study: Sofa Super Store, NIST, 100 Bureau Dr., Stop 8660, Gaithersburg, MD 20899-8660.

Once the final report is published, NIST will work with the appropriate committees of the International Code Council (ICC) on using the study’s recommendations to improve provisions in model building and fire codes. NIST also will work with the major organizations representing state and local governments—including building and fire officials—and firefighters to encourage them to seriously consider its recommendations.

Recommendations from the NIST Study of the Charleston Sofa Super Store Fire

1. High Fuel-Load Mercantile Occupancies: NIST recommends that, at a minimum, all state and local jurisdictions adopt a building and fire code based upon one of the model codes, covering new and existing high fuel-load mercantile occupancies, and update local codes as the model codes are revised.

2.   Model Code Adoption and Enforcement: NIST recommends that all state and local jurisdictions implement aggressive and effective fire inspection and enforcement programs that address:

a) all aspects of the building and fire codes;
b) adequate documentation of building permits and alterations;
c) the means of inspecting fire protection systems and detailing record keeping;
d) the frequency and rigor of fire inspections, including follow-up and auditing procedures; and
e) guidelines for remedial requirements when inspections identify deviations from code provisions.

3.  Qualified Fire Inspectors and Building Plan Examiners: NIST recommends that all state and local jurisdictions ensure that fire inspectors and building plan examiners are professionally qualified to a national standard such as National Fire Protection Association (NFPA) 1031.

4.  Sprinklers: NIST recommends that model codes require sprinkler systems and that state and local authorities adopt and aggressively enforce this provision:

a) for all new commercial retail furniture stores regardless of size; and
b) for existing retail furniture stores with any single display area of greater than 190 square meters (2,000 square feet).

5.  Comprehensive Risk Management Plans:  NIST recommends that state and local jurisdictions use comprehensive risk management plans to:

a) identify low, medium, and high hazard occupancies;
b) allocate resources according to risk identified; and
c) develop operating procedures that respond to specific risks.

6.  Ventilation of Burning Structures: NIST recommends that state and local authorities: 

a) develop guidelines as to how and when ventilation should be implemented during a fire; and
b) provide training to fire fighters on different types of ventilation—vertical, horizontal and positive-pressure—and integrate into daily operations on the fire ground.

7.  Research on Upholstered Furniture Flame Spread: NIST recommends that research be conducted to better understand ignition and fire spread on upholstered furniture in order to provide the tools needed by design professionals to improve the fire performance of furniture. The specific areas requiring research are:

a) prediction of ignition of natural and synthetic coverings for current furniture, wall, ceiling and floor lining materials, and room furnishings;
b) prediction of fire spread over actual furniture with and without fire barriers, fire retardants and fire resistive materials; and
c) quantification of smoke and toxic gas production in realistic room fires.

8.  Research on Improving Fire Barriers: NIST recommends that research be conducted to provide the tools needed by design professionals to improve the performance of compartmentalization. The specific areas requiring research are:

a) prediction of fire spread through walls constructed of wood, metal and gypsum wallboard;
b) prediction of fire spread through doors constructed of glass, wood, and metal;
c) prediction of fire spread through penetrations; and
d) prediction of performance of roll-up fire doors in actual fires and after extended service. 

9.  Research on Decision Aids for Allocation of Resources: NIST recommends that research be conducted to:

a) refine computer-aided decision tools for determining the costs and benefits of alternative code changes and fire safety technologies; and
b) develop computer models to assist communities in allocating resources (money and staff) to ensure that their response to an emergency with a large number of potential casualties is effective.

10.  Research on Ventilation of Burning Structures: NIST recommends that additional research be conducted to:

a) improve characterization of how ventilation affects the growth and spread of fire within structures; and
b) provide the fire service with guidance on when and how to use ventilation to improve the fire environment during fire service operations.

11.  Research on Performance Metrics for Fire Protection: NIST recommends that research be conducted to:

a) develop performance and effectiveness metrics for community fire protection;
b) survey effectiveness of existing fire services; and
c) use metrics to optimize development of new technologies.

NIST has more than 40 years of experience conducting building and fire safety studies and researching the aftermath of disasters and failures. By understanding the technical causes for such incidents and making the information available to the public, NIST scientists and engineers strive to improve the safety of buildings, their occupants and emergency responders. NIST’s technical building failure and fire studies do not address fault.

    On March 30, 2010, a 28-year-old male career fire fighter/paramedic (victim) died and a 21-year-old female part-time fire fighter/paramedic was injured when caught in an apparent flashover while operating a hoseline within a residence. Units arrived on scene to find heavy fire conditions at the rear of a house and moderate smoke conditions within the uninvolved areas of the house. A search and rescue crew had made entry into the house to search for a civilian who was entrapped at the rear of the house. The victim, the injured fire fighter/paramedic, and a third fire fighter made entry into the home with a charged 2 ½ inch hoseline. Thick, black rolling smoke banked down to knee level after the hoseline was advanced 12 feet into the kitchen area. While ventilation activities were occurring, the search and rescue crew observed fire rolling across the ceiling within the smoke. They immediately yelled to the hoseline crew to “get out.” The search and rescue crew were able to exit the structure safely, then returned to rescue the injured fire fighter/paramedic first and then the victim. The victim was found wrapped in the 2 ½ inch hoseline that had ruptured and without his facepiece on. He was quickly brought out of the structure, received medical care on scene, and was transported to a local hospital where he was pronounced dead.

    Contributing Factors

    • Well involved fire with entrapped civilian upon arrival
    • Incomplete 360 degree situational size-up
    • Inadequate risk-versus-gain analysis
    • Ineffective fire control tactics
    • Failure to recognize, understand, and react to deteriorating conditions
    • Uncoordinated ventilation and its effect on fire behavior
    • Removal of self-contained breathing apparatus (SCBA) facepiece
    • Inadequate command, control, and accountability
    • Insufficient staffing.

    Key Recommendations

    • Ensure that a complete 360 degree situational size-up is conducted on dwelling fires and others where it is physically possible and ensure that a risk-versus-gain analysis and a survivability profile for trapped occupants is conducted prior to committing to interior fire fighting operations
    • Ensure that interior fire suppression crews attack the fire effectively to include appropriate fire flow for the given fire load and structure, use of fire streams, appropriate hose and nozzle selection, and adequate personnel to operate the hoseline
    • Ensure that fire fighters maintain crew integrity when operating on the fireground, especially when performing interior fire suppression activities
    • Ensure that fire fighters and officers have a sound understanding of fire behavior and the ability to recognize indicators of fire development and the potential for extreme fire behavior
    • Ensure that incident commanders and fire fighters understand the influence of ventilation on fire behavior and effectively coordinate ventilation with suppression techniques to release smoke and heat
    • Ensure that fire fighters use their self-contained breathing apparatus (SCBA) and are trained in SCBA emergency procedures.

    Recommendations

    Recommendation #1: Fire departments should ensure that a complete 360 degree situational size-up is conducted on dwelling fires and others where it is physically possible and ensure that a risk-versus-gain analysis and a survivability profile for trapped occupants is conducted prior to committing to interior fire fighting operations.

    Discussion: Among the most important duties of the first officer on the scene is conducting an initial 360 degree situational size-up of the incident. A proper size-up begins from the moment the alarm is received, and it continues until the fire is under control. The size-up should include an evaluation of factors such as the fire size and location, length of time the fire has been burning, conditions on arrival, occupancy, fuel load and presence of combustible or hazardous materials, exposures, time of day, available staffing on scene or en route, and weather conditions. Information on the structure itself should include size, construction type, age, condition (e.g., evidence of deterioration, weathering), renovations, lightweight construction, loads on roof and walls (e.g., air conditioning units, ventilation ductwork, utility entrances), and available preplan information-all key information that can affect whether an offensive or defensive strategy is employed. The size-up should also include a risk-versus-gain assessment during incident operations, especially after primary searches have been conducted, situational awareness, and a survivability profile.

    Even before the IC takes command of an incident he will be faced with having to determine what critical tasks are going to have to be performed to bring the incident under control. He will use current knowledge and previous experience to formulate a plan for his arriving apparatus and personnel. When the IC arrives he needs to ascertain as much information as possible to make a determination whether his plan will still work. The IC may be faced with several priorities such as an entrapped civilian, a larger scale incident then previously determined, and the fire environment itself. This is additionally part of the initial situational size-up and the risk assessment, which will constantly change as the incident progresses until it is brought under control. The IC should be willing to prioritize and change his strategy and plan based on these assessments. Situational awareness is a highly critical aspect of human decision making: the understanding of what is happening around you, projecting future situation events, comprehending information and its relevance, being realistic, and an individual’s perception. Conducting accurate risk assessments and receiving interior/exterior status updates is critical to the safety of fire fighters in the incident, rescue/recovery efforts, and overall control of the incident. “The decision to commit interior fire fighting personnel should be made on a case-by-case basis with proper risk-benefit decisions being made by the incident commander. The commitment of firefighters’ lives for saving property and an unknown or marginal risk of civilian life must be balanced appropriately.”

    Another tool that the IC should consider using is survivability profiling. Survivability profiling uses the knowledge learned of fire behavior and spread, smoke (i.e., color, condition, movement), and building construction to examine a situation and make an intelligent decision of whether to commit fire fighters to life saving and/or interior operations. In other words, survivability profiling involves assessing the probability that a trapped occupant is still alive and can safely be rescued with the current or impending conditions. The NIOSH publication Preventing Deaths and Injuries of Fire Fighters Using Risk Management Principles at Structure Fires states that the IC must make a determination that offensive (interior) operations may be conducted without exceeding a reasonable degree of risk to fire fighters before ordering an offensive attack and must be prepared to discontinue the offensive attack if the risk evaluation changes during the fire fighting operation. The fireground is very dynamic, and conditions can either improve or deteriorate based on fire suppression activities, and available resources. Most importantly, assessments/size-ups of the incident are necessary to detect a change on the fireground.

    During this incident, the responding departments were made aware while en route that there was a paralyzed civilian entrapped in the structure. His wife advised 911 and arriving units that the chair he was sitting in caught fire with him still in it. Units arrived on scene 6 minutes after the 911 call to find heavy fire conditions to the addition on the C-side of the house where the entrapped civilian was last seen by his wife sitting in the chair. Prior to a complete 360 degree situational size-up, decisions were made to send a hoseline crew through the A-side front door to assist with search and rescue, and to locate and attack the fire (located on the C-side in the addition and garage). Fire fighters entering the house from the A-side were initially met with moderate smoke conditions banked down to waist level, which quickly changed to thick, black smoke conditions that went to the floor due to the fire being uncontrolled and spreading into the house from the C-side. The victim and injured fire fighter/paramedic were eventually exposed to a flashover. The civilian was not rescued. A full range of factors must be considered in making the risk evaluation including a realistic evaluation of the ability to execute a successful offensive fire attack with the resources that are available and a realistic evaluation of occupant survivability and rescue potential.

    Fire departments should be aware of the recently released 2010 International Association of Fire Chiefs’ (IAFC) Rules of Engagement (ROE) of Structural Firefighting. These guidelines recommend that ICs conduct or obtain a 360 degree situational incident size-up, determine the occupant survival profile, and conduct an initial risk assessment.

    Recommendation #2: Fire departments should ensure that interior fire suppression crews attack the fire effectively to include appropriate fire flow for the given fire load and structure, use of fire streams, appropriate hose and nozzle selection, and adequate personnel to operate the hoseline.

    Discussion: An assessment and decision of suppression methods must be made before attacking a fire in hopes of extinguishing it and keeping fire fighters safe while doing so. To accomplish such tasks, ICs, officers, and fire fighters need to consider such factors as fire load and flow, hose and nozzle selection, placement and use of fire streams, and required staffing. Fire load, or heat released from combustible materials, will directly affect how the fire develops throughout the incident and how long and severely it may burn. The more combustible materials involved, the greater the heat that will be produced requiring additional fire flow. Fire flow is the calculated amount of water in gallons per minute needed to extinguish a fire in a specific structure. To assist fire fighters in calculating the fire flow, one of three formulas could be used: the Iowa Rate-of-Flow Formula, the National Fire Academy (NFA) Formula, and the Insurance Services Office Formula. The Iowa Rate-of-Flow and NFA Formulas were designed to be used on the fireground because they allow fire fighters to mentally compute the fire flow with relative ease by estimating such things as the square footage (area) of a structure or the cubic footage (volume) of a room, and percentage involved, then inputting that data into a predetermined formula.

    Iowa Rate-of-Flow Formula: rate of fire flow=volume of room in cubic feet÷100

    NFA Formula: fire flow in gallons per minute for one floor at 100% involvement=(length ×width)÷3. If less than 100% involvement,then multiply answer by estimated percentage of involvement.

    The fire stream, or water stream, is an important aspect both for fire fighter safety and tactical considerations. The wrong choice of fire stream can place a fire fighter and crew in a bad situation. Also, the wrong type of fire stream will affect the tactical outcome of the incident in regards to how quickly the fire is controlled. To produce an effective fire flow, there must be a viable water supply; sufficient water pressure; a means to transport the stream to the desired point (fire); and trained, competent personnel to deploy these three elements. These elements are applied through the use of a fire hose and nozzle. The diameter of the fire hose can affect how much water is flowed on a fire, but the larger the diameter, the more potential to max out the delivering pump’s capacity, and additional personnel will be needed to handle the hoseline. The nozzle will allow the water to leave its mechanical hold within the hoseline to produce the desired fire stream. Typical fire streams include solid, fog, and broken, and each have their own characteristics, advantages/disadvantages, and application. Proper training on all these aspects will greatly influence fire fighter’s knowledge on the fireground, provide for quicker control and extinguishment of the fire, and increase overall fire fighter safety.

    During this incident, arriving fire departments were faced with a large volume of fire and an entrapped civilian. Prior to the flashover, the fire was burning uncontrolled at the rear of the house (house addition and garage) and spreading into the house. FF1, the victim, and injured fire fighter/paramedic were tasked with advancing a charged 2½-inch hoseline into the house to assist with the search and for fire suppression. They were able to advance this hoseline approximately 12 feet into the house, but advancing and operating a large-diameter hoseline within tight quarters may be extremely cumbersome even if adequate staffing is available to accomplish this task. Note: When FF1 had a problem with his PPE, he handed the nozzle over to the victim, and eventually backed out of the structure, that left only two personnel available to operate the hoseline. Fire fighters and officers need to understand that while a 2½-inch hoseline provides a greater flow, fire fighters need to be able to move the line quickly and efficiently interiorly, especially when performing a search and experiencing deteriorating fire conditions. An alternate decision to advancing the 2½-inch hoseline into the small house could have been to deploy and advance a 1¾-inch hoseline(s), which would have been easier to maneuver within the house.

    Due to the large volume of fire at the C-side that was extending into the house, the 2½-inch hoseline(s) could have been deployed exteriorly to the B- and/or D-sides to combat the fire, paying close attention to directly attack the fire, an elevated master stream (carefully directed on fire burning uncontrolled within the addition and garage) could have been deployed early into the fire had the assessment been made that the entrapped civilian (last reported to be in the addition) could not be saved, thus possibly stopping further progression of fire and volatile smoke into the house. Additionally, a lightweight portable master stream, placed exteriorly at the B- and/or D-sides, which is fairly easy to deploy by using a 2½- to 3-inch supply line, may only require one fire fighter to operate once in position. These types of water delivery appliances are capable of delivering a large volume of water that will assist in extinguishing the fire from an exterior position, especially when conditions are deteriorating interiorly, which could place fire fighter’s safety at risk.

    An incident commander needs to constantly assess whether his strategies and tactics to control and extinguish the fire are working, paying close attention to fire and smoke conditions/changes, the affects from ventilation performed by fire fighters and occurring naturally as the fire progresses, and to fire fighter safety.

    Recommendation #3: Fire departments should ensure that fire fighters maintain crew integrity when operating on the fireground, especially when performing interior fire suppression activities.

    Discussion: Fire fighters should always work and remain in teams whenever they are operating in a hazardous environment. Team integrity depends on team members knowing who is on their team and who is the team leader; staying within visual contact at all times (if visibility is low, teams must stay within touch or voice distance of each other); communicating needs and observations to the team leader; and rotating together for team rehab, team staging, and watching out for each other (e.g., practicing a strong buddy system). Following these basic rules helps prevent serious injury or even death by providing personnel with the added safety net of fellow team members. Teams that enter a hazardous environment together should leave together to ensure that team continuity is maintained.The 2010 IAFC ROE of Structural Firefighting states, “Go in together, stay together, come out together.”

    Recommendation #4: Fire departments should ensure that fire fighters and officers have a sound understanding of fire behavior and the ability to recognize indicators of fire development and the potential for extreme fire behavior.

    Discussion: Reading fire behavior indicators and recognizing fire conditions serve as the basis for predicting likely and potential fire behavior. Reading the fire requires recognition of patterns of key fire behavior indicators. It is essential to consider these indicators together and not to focus on the most obvious indicators or one specific indicator (e.g., smoke). Identifying building factors, smoke, wind direction, air movement, heat and flame indicators are all critical to reading the fire. Focusing on reading “smoke” may result in fire fighters missing other critical indicators of potential fire behavior. One important concept that must be emphasized is that smoke is fuel and must be viewed as potential energy. Smoke that is thick, black and pressurized can emit from a structure at a high rate. This is indicative of a potentially under-ventilated structure or a ventilation controlled fire. This smoke is fuel-rich and is termed “black fire.” It can potentially do as much damage as fire itself, but it is an indicator that some type of extreme fire behavior may occur.

    Since the IC should be staged at a designated command post (outside), the interior conditions should be communicated by interior company officers (or the member supervising the crew) as soon as possible to their supervisor (e.g., IC, division supervisor). Knowledge of interior conditions could change the IC’s strategy or tactics. Interior crews can aid the IC in this process by providing reports of the interior conditions as soon as they enter the fire building and by providing regular updates. In addition to the importance of communicating reports on fire conditions, it is essential that fire fighters recognize what type of information is important. Command effectiveness can be impaired by excessive and extraneous information as well as from a lack of information. In the case of communicating observations related to fire behavior, this requires development of fire fighters’ skill in recognition of key fire behavior indicators and reading the fire.

    During this incident, FF1 made a decision to quickly open and close the smooth bore nozzle (water applied as a solid stream) while aiming at the ceiling. It is believed this was done in an attempt to cool the thermal (hot gas) layer, a common practice, in hopes of preventing a potential flashover. Ceiling temperatures can be reduced through carefully considered fire control actions, such as applying short bursts of water spray into the hot gas layer, or directly applying water onto the fire itself which will limit the release of unburned products of combustion as well as reduce ceiling temperature.

    Also, the search and rescue crew (operating without the protection of a hoseline) were able to make a quick determination that the conditions within the house were imminent to flashover. They made an attempt to alert the victim and injured fire fighter/paramedic, but were too late. If conditions are right for a flashover, there are only seconds to make a decision. Fire fighters will be met with a sudden increase in heat and rollover within the ceiling level. The injured fire fighter/paramedic was unaware that the conditions she was operating in deteriorated quickly. She remembers thick, black smoke pushing down to the floor while in the structure and then “the room and everything in it caught fire.” Prior to the flashover, windows on the B-side were vented and thick, black and heavily pressurized smoke billowed from these windows. The IC, and individuals working on the exterior, need to recognize this as a potential for extreme fire behavior and evacuate interior crews. Obtaining proper training and hands-on experience through the use of a flashover simulator may assist interior fire fighters in making sound decisions on when to evacuate a structure fire.

    Recommendation #5: Fire departments should ensure that incident commanders and fire fighters understand the influence of ventilation on fire behavior and effectively coordinate ventilation with suppression techniques to release smoke and heat.

    Discussion: Ventilation is the systematic removal of heated air, smoke, and fire gases from a burning building and replacing them with cooler air.1 The two types of ventilation are vertical and horizontal. During vertical ventilation the natural convection of the heated gases creates upward currents that draw the fire and heat in the direction of the vertical opening. Horizontal ventilation allows for heat, smoke, and gases to escape by means of a doorway or window but is highly influenced by the location and extent of the fire, and special caution should be taken if the fire is in the attic.

    Properly coordinated ventilation can decrease the rate the fire spreads, increase visibility, and lower the potential for flashover or backdraft. Proper ventilation reduces the threat of flashover by removing heat before combustibles in a room or enclosed area reach their ignition temperatures. Proper ventilation can reduce the risk of a backdraft by reducing the potential for superheated fire gases and smoke to accumulate in an enclosed area. Properly ventilating a structure fire will reduce the tendency for rising heat, smoke, and fire gases, trapped by the roof or ceiling, to accumulate, bank down, and spread laterally to other areas within the structure. The ventilation opening may produce a chimney effect, causing air movement from within a structure toward the opening. These air movements help facilitate the venting of smoke, hot gases, and products of combustion but may also cause the fire to grow in intensity and may endanger fire fighters who are between the fire and the ventilation opening. For this reason, ventilation should be closely coordinated with hoseline placement and offensive fire suppression tactics. Close coordination means the hoseline is in place and ready to operate, so that when ventilation occurs, the hoseline can overcome the increase in combustion, which is likely to occur. If a ventilation opening is made directly above a fire, fire spread may be reduced, allowing fire fighters the opportunity to extinguish the fire. If the opening is made elsewhere, the chimney effect may actually contribute to the spread of the fire.1

    ICs and fire fighters need to consider the following and how it will affect ventilation and overall control of the fire:

    • Who will ventilate (knowledge and skills)?
    • What type of ventilation?
    • When to ventilate?
    • Where to ventilate?
    • Why ventilate?
    • How to properly and safely ventilate?
    • What are the expected results from ventilation?

    Fire development in a compartment may be described in several stages, although the boundaries between these stages may not be clearly defined.1 The incipient stage starts with ignition, followed by growth, fully developed, and decay stages. The available fuel largely controls the growth of the fire during the early stages. This is known as a fuel-controlled fire, and ventilation during this time may initially slow the spread of the fire as smoke, hot gases, and products of incomplete combustion are removed. As noted above, increased ventilation can also cause the fire to grow in intensity as additional oxygen is introduced. Effective application of water during this time can suppress the fire but if the fire is not quickly knocked down, it may continue to grow.

    If the fire grows until the compartment approaches a fully developed state, the fire is likely to become ventilation controlled. Further fire growth is limited by the available air supply as the fire consumes the oxygen in the compartment. Ventilating the compartment at this point will allow a fresh air supply (with oxygen to support combustion), which may accelerate the fire growth, resulting in an increased heat release rate. If coordinated fire suppression activities do not quickly decrease the heat release rate, a ventilation induced flashover can occur.1 Considering that most fires beyond the incipient stage are or will quickly become ventilation controlled, changes in ventilation are likely to be some of the most significant factors in changing fire behavior.

    During this incident, uncoordinated ventilation occurred while the hoseline and search and rescue crews were inside the house. The victim and other fire fighters, within the small house, were between the fire and the ventilation source. One fire fighter accounts heavy, turbulent, black smoke pushing from a window on the B-side after it was broken. Shortly after, the house sustained an apparent ventilation-induced flashover.

    Recommendation #6: Fire departments should ensure that fire fighters use their self-contained breathing apparatus (SCBA) and are trained in SCBA emergency procedures.

    Discussion: Fire fighters are tasked at times to operate within environments which pose inhalation hazards (e.g., toxic smoke and oxygen deficiency),defined by the Occupational Safety and Health Administration (OSHA) as immediately dangerous to life and health (IDLH). Proper training along with an implemented and enforced policy or procedure will assist fire fighters with proper maintenance, use, and removal of a SCBA. OSHA 29 CFR 1910.134 (g)(4)(iii) states, “The employer shall ensure that all employees engaged in interior structural firefighting use SCBAs.”

    According to the autopsy report, the victim died from carbon monoxide intoxication due to inhalation of smoke and soot. The medical examiner also indicated that the victim’s COHb level (a measure of carbon monoxide in the bloodstream) was 30%. Even if nothing but carbon dioxide, water vapor, and nitrogen were present in the fire products and these were to mix with the air being breathed by a fire fighter, then the oxygen percentage would be reduced below the normal 21%. At 15% oxygen, fire fighters can experience lethargy, poor coordination, and confused thinking. The two principal toxins in smoke—carbon monoxide and hydrogen cyanide—act to deprive the brain of oxygen, and their effects would be enhanced due to the lower levels of oxygen in the air. The victim was discovered with his facepiece off, but still connected to his regulator. Due to the smoke conditions, the victim would have had to have been on air when entering the structure. It has not been determined why the victim was found without his facepiece on.

    Emergencies created by, or associated with, SCBA can be overcome in several ways. Fire departments can develop and implement a comprehensive respiratory protection program that includes fire fighter fitness, training, and competency and skill assessments in SCBA and emergency procedures. Firefighters should remember the first rule in any emergency situation-to not panic. Panic causes an increased breathing rate and consequently, an increase in air consumption; and an inability to focus on emergency procedures. If fire fighters become lost, trapped, or disoriented, they need to focus on managing remaining air in their SCBA cylinder until other fire fighters can make a rescue attempt. Removing one’s facepiece in an IDLH atmosphere can immediately expose the respiratory system to a potentially fatal environment, thus incapacitating an individual. Choosing to leave one’s SCBA facepiece on may be the best chance in providing additional time for a fire fighter to be rescued. Fire fighters should follow their department’s SOPs regarding emergency SCBA procedures and emergency communications.

    Recommendation #7: Fire departments should ensure that adequate staffing is available to respond to emergency incidents.

    Discussion: NFPA 1710 Standard for the Organization and Deployment of Fire Suppression Operations, Emergency Medical Operations, and Special Operations to the Public by Career Fire Departments contains recommended guidelines for minimum staffing of career fire departments. NFPA 1710 states the following: “On-duty fire suppression personnel shall be comprised of the numbers necessary for fire-fighting performance relative to the expected fire-fighting conditions. These numbers shall be determined through task analyses that take the following factors into consideration:

    1. Life hazard to the populace protected.
    2. Provisions of safe and effective fire-fighting performance conditions for the fire fighters.
    3. Potential property loss.
    4. Nature, configuration, hazards, and internal protection of the properties involved.
    5. Types of fireground tactics and evolutions employed as standard procedure, type of apparatus used, and results expected to be obtained at the fire scene.

    The NFPA standard states that both engine and truck companies shall be staffed with a minimum of four on-duty personnel. The standard also states that companies shall be staffed with a minimum of five or six on-duty members in jurisdictions with tactical hazards, high-hazard occupancies, high-incident frequencies, geographical restrictions, or other pertinent factors identified by the authority having jurisdiction.

    During this incident, the victim’s department responded with three personnel on the engine and two personnel on the ambulance, but the Still assignment also consisted of an engine, two ladder trucks, and a squad, with four fire personnel on each. It was routine to have an ambulance respond with an engine on a first due fire assignment. Due to short staffing, the ambulance personnel were tasked with fire suppression activities, thus taking them out-of-service as a medical unit. Also, due to short staffing, the lieutenant/acting officer (IC) was required to ride and operate as the officer of E534. This removed him from his command response vehicle which would have allowed him to command at a tactical level versus having to potentially perform tasks.

    Recommendation #8: Fire departments should ensure that staff for emergency medical services is available at all times during fireground operations.

    Discussion: Although there is no evidence that this recommendation would have prevented this fatality, it is being provided as a reminder of a good safety practice. Emergency medical care and transportation for injured or ill fire fighters should be immediately available on the scene of working structure fires. Many fire departments incorporate an automatic dispatch of an EMS unit to working structure fires. Automatic dispatch can help to ensure that qualified emergency medical care and transportation for injured or ill fire fighters is available without having to call and wait for a unit after a medical emergency or injury has occurred.

    During this incident, the victim and the injured fire fighter/paramedic responded in an ambulance. Upon their arrival to the scene, the IC immediately tasked them with interior operations due to staffing issues. The IC did not request an additional ambulance to respond to the scene for medical care until after the victim was down within the house. Additional resources (e.g., apparatus and personnel) arrived minutes after the ambulance’s arrival.

    Recommendation #9: Fire departments and dispatch centers should ensure they are capable of communicating with each other without having to monitor multiple channels/frequencies on more than one radio.

    Discussion: Although there is no evidence that this recommendation would have prevented this fatality, it is being provided as a reminder of a good safety practice. It is important that fire service personnel have an efficient means of communicating during an emergency incident. The use of radio communications provides fire fighters on scene with the ability to communicate to individuals they cannot see or to receive vital information about the incident. To assist with this, localities should ensure that communications can occur without having to utilize different radios and/or monitor multiple channels/frequencies.

    During this incident, the IC had to monitor more than one radio and even had to go to the cab of his engine to accomplish this task. Having to monitor multiple radios and potentially take your eyes off the scene for a moment could be extremely detrimental to the management of the incident.

    Recommendation #10: Fire departments should ensure that the incident commander, or designee, maintains close accountability for all personnel operating on the fireground.

    Discussion: Although there is no evidence that this recommendation would have prevented this fatality, it is being provided as a reminder of a good safety practice. The use of an accountability system is recommended by NFPA 1500 Standard on Fire Department Occupational Safety and Health Program and NFPA 1561 Standard on Emergency Services Incident Management System.21 A functional personnel accountability system requires the following:

    • Development of a departmental SOP
    • Training all personnel
    • Strict enforcement during emergency incidents

    As the incident escalates, additional staffing and resources may be needed, adding to the burden of tracking personnel. At this point, an accountability system should be in place which includes an incident command board that is established and maintained by an assigned accountability officer or aide. A properly maintained incident command board allows the IC to readily identify the location and time of all fire fighters on the fireground. As a fire escalates and additional fire companies respond, a chief’s aide or accountability officer assists the IC with accounting for all fire fighting companies at the fire, at the staging area, and at the rehabilitation area. The personnel accountability report (PAR) is an organized on-scene roll call in which each supervisor reports the status of his crew when requested by the IC or emergency dispatcher.1 A properly initiated and enforced accountability system on every response, which is consistently integrated into fireground command and control, enhances fire fighter safety and survival by helping to ensure a more timely and successful identification and rescue of a disoriented or downed fire fighter.

    During this incident, the accountability system was never set in place and a PAR was not conducted following the Mayday.

    Recommendation #11: Fire departments should ensure that fire fighters wear a full array of turnout clothing and personal protective equipment appropriate for the assigned task while participating in fire suppression.

    Discussion: Although there is no evidence that this recommendation would have prevented this fatality, it is being provided as a reminder of a good safety practice. NFPA 1500 Standard on Fire Department Occupational Safety and Health Program states, “The fire department shall provide each member with protective clothing and protective equipment that is designed to provide protection from the hazards to which the member is likely to be exposed and is suitable for the tasks that the member is expected to perform…protective clothing and protective equipment shall be used whenever a member is exposed or potentially exposed to the hazards for which the protective clothing (and equipment) is provided.” NFPA 1971 Standard on Protective Ensembles for Structural Fire Fighting and Proximity Fire Fighting has established minimum requirements for structural fire fighting protective ensembles and ensemble elements designed to provide fire fighting personnel limited protection from thermal, physical, environmental, and bloodborne pathogen hazards encountered during structural fire fighting operations. These requirements will assist in protecting firefighters, but only if they wear the PPE as recommended by the manufacturer.

    During this incident, the victim was discovered without a hood over his head or rolled down on his neck. NIOSH investigators could not determine whether this equipment was properly donned prior to the incident.

    Recommendation #12: Fire departments should ensure that a separate incident safety officer, independent from the incident commander, is appointed at each structure fire.

    Discussion: Although there is no evidence that this recommendation would have prevented this fatality, it is being provided as a reminder of a good safety practice. According to NFPA 1561 Standard on Emergency Services Incident Management System,“The incident commander shall have overall authority for management of the incident and the incident commander shall ensure that adequate safety measures are in place.” This shall include overall responsibility for the safety and health of all personnel and for other persons operating within the incident management system. While the incident commander is in overall command at the scene, certain functions must be delegated to ensure adequate scene management is accomplished.According to NFPA 1500 Standard on Fire Department Occupational Safety and Health Program,“as incidents escalate in size and complexity, the incident commander shall divide the incident into tactical-level management units and assign an incident safety officer (ISO) to assess the incident scene for hazards or potential hazards.” These standards indicate that the incident commander is in overall command at the scene but acknowledge that oversight of all operations is difficult. On-scene fire fighter health and safety is best preserved by delegating the function of safety and health oversight to the ISO. Additionally, the incident commander relies upon fire fighters and the ISO to relay feedback on fireground conditions in order to make timely, informed decisions regarding risk versus gain and offensive-versus-defensive operations. The safety of all personnel on the fireground is directly impacted by clear, concise, and timely communications among mutual aid fire departments, sector command, the ISO, and the incident commander. NFPA 1521 Standard for Fire Department Safety Officer defines the role of the ISO at an incident scene and identifies duties such as recon of the fireground and reporting pertinent information back to the incident commander; ensuring the department’s accountability system is in place and operational; monitoring radio transmissions and identifying barriers to effective communications; and ensuring established safety zones, collapse zones, hot zones, and other designated hazard areas are communicated to all members on scene. Larger fire departments may assign one or more full-time staff officers as safety officers who respond to working fires. In smaller departments, every officer should be prepared to function as the ISO when assigned by the incident commander. The presence of a safety officer does not diminish the responsibility of individual fire fighters and fire officers for their own safety and the safety of others. The ISO adds a higher level of attention and expertise to help the fire fighters and fire officers. The ISO must have particular expertise in analyzing safety hazards and must know the particular uses and limitations of protective equipment.3

    Recommendation #13: Fire departments should ensure that all fire fighters are equipped with a means to communicate with fireground personnel before entering a structure fire.

    Discussion: Although there is no evidence that this recommendation would have prevented this fatality, it is being provided as a reminder of a good safety practice. NFPA 1561 Standard on Emergency Services Incident Management System states, “To enable responders to be notified of an emergency condition or situation when they are assigned to an area designated as immediately dangerous to life or health (IDLH), at least one responder on each crew or company shall be equipped with a portable radio and each responder on the crew or company shall be equipped with either a portable radio or another means of electronic communication. Radio communications on the fireground are imperative for the IC to command and control the incident and for fire fighters to work effectively and safely within a structure fire. Fire fighters within a structure are unable to see all areas affected by fire and whether the structure is maintaining its stability. Having radio communications can enhance fire fighter safety and health by providing fire fighters a means to communicate with other crew members or with the IC when they find themselves in need of assistance.

    During this incident, the victim did have a radio, but it was positioned in the back pocket of his station pants. Thus, when he donned his bunker pants, his radio became inaccessible during the incident.

    Recommendation #14: The National Fire Protection Association (NFPA) should consider developing more comprehensive training requirements for fire behavior to be required in NFPA 1001 Standard for Fire Fighter Professional Qualifications and NFPA 1021 Standard for Fire Officer Professional Qualifications.

    Discussion: Structural fires frequently display indicators and warning signs of rapid fire development such as flashover, backdraft, and fire gas ignition for which many fire fighters and officers may not have been sufficiently trained to recognize or understand. It is imperative that fire fighters and officers develop the understanding and skills necessary to identify and interpret the indicators so that they can anticipate the potential for extreme fire behavior and immediately communicate their findings to the IC.  This requires comprehensive training in fire behavior (theory) and practical application inclusive of realistic live fire training.

    NFPA 1001 Standard for Fire Fighter Professional Qualifications and NFPA 1021 Standard for Fire Officer Professional Qualifications were developed to ensure that fire fighters and officers have the skills necessary to perform their job, also known as job performance requirements (JPRs). Currently, these JPRs include language that individuals have requisite knowledge on such topics as heat transfer, principles of thermal layering, advantages and disadvantages of different types of ventilation, and fire behavior in a structure. These standards do not include guidance on how many hours or what available scientific information will be used to verify that an individual has a sound understanding of the physical, chemical, and thermal behavior of fire and how to make a connection between fire dynamics/behavior and the influence of tactical operations (e.g., fire flow, types of ventilation) and external factors (e.g., wind). These JPRs are taken by curriculum developers and formatted into educational content. Standard setting agencies, states, curriculum developers, and other authorities having jurisdiction should consider developing a nationwide curriculum so that fire fighters and officers receive fundamental and refresher training on how to: recognize and interpret fire behavior and indications of impending extreme fire behavior (e.g., flashover, back draft, smoke explosion); and, anticipate what could or should happen when a tactical operation is performed (e.g., ventilation, fire flow). Standard setting agencies and curriculum developers should also consider providing guidelines (e.g., required topics and hours) for instructors to deliver such information and recommendations for verifying an individual’s learning and retention.

    According to documented training reviewed by NIOSH investigators, the victim, injured fire fighter/paramedic, and IC had a combined 24 hours of fire behavior training out of 5,654 total combined training hours. Additional fire behavior training to include such areas as theory, chemistry, physics, smoke reading, current research, and the cause and effects of tactics during fire suppression operations may improve fire fighter safety.

    Newest NIOSH Alert: Preventing Deaths and Injuries of Fire Fighters at Structure Fires

    2 comments

    NIOSH released it’s latest Alert on Firefighter Risk Reduction. Fire fighters are often killed or injured when fighting fires in abandoned, vacant, and unoccupied structures. These structures pose additional and sometimes unique risks due to the potential for fire fighters to encounter unexpected and unsafe building conditions such as dilapidation, decay, damage from previous fires and vandals, and other factors such as uncertain occupancy status. Risk management principles must be applied at all structure fires to ensure the appropriate strategy and tactics are used based on the fireground conditions encountered.

    Fire fighters should take the following steps to minimize their risk of death and injury while fighting structure fires:

    • Report conditions and hazards encountered to your officer, incident commander, or incident safety officers
    • Recognize that maintaining your safety is a shared responsibility
    • Comply with your department’s standard operating procedures (SOPs) / standard operating guidelines (SOGs) and safety rules.
    • Be constantly aware of your surroundings and changing conditions.

    Fire departments (chief officers, company officers and policy makers) should take the following steps to protect fire fighters:

    • Develop and enforce risk management plans, policies, and standard operating procedures and guide-lines (SOPs/SOGs) for risk management.
    • Train incident commanders, incident safety officers, and fire fighters in the fire department risk management plans and SOPs/SOGs for risk management.

    Develop and implement fire department policies and SOPs/SOGs for emergency response and fire-fighting activities in and around abandoned, vacant, or unoccupied structures.

    • A thorough size-up and risk analysis should be performed before conducting operations in any burning structure.
    • Fire-fighting operations should be limited to defensive (exterior) strategy if the structure is judged to be unsafe and in any situation where the risks to fire fighter safety are excessive.
    • Offensive (interior attack) operations should only be considered when sufficient resources are on scene to conduct offensive operations with a reasonable degree of safety, including the ability to perform essential support functions (i.e., water supply, ventilation, lighting, utility control, accountability, rapid intervention teams).
    • Additional size-ups and risk analyses should be performed before changing strategies, including any decision to conduct interior overhaul operations following a defensive fire attack.
    • Have adequate resources available on scene to per-form rapid intervention team (RIT) duties anytime personnel are operating at any structure fire.
    • Inspect and preplan buildings within your jurisdiction. Note the type of construction, materials used, presence of trusses and/or lightweight construction in the roof and floor, type of occupancy, fuel load, exit routes, and other distinguishing characteristics.
    • Enter preplan information into the dispatch computer so that when a fire is reported at a preplanned location, the critical information is provided to all responding units. Adopt and enforce a standard system of marking dangerous abandoned, derelict, and vacant buildings, based on a prefire assessment of their structural conditions and other risk factors, in cooperation with municipal agencies and local authorities such as local housing authorities.
    • Train fire fighters and officers to recognize the marking system and incorporate the information into their size-up considerations. Additionally, local authorities should ensure programs are in place that provide for the demolition and removal of structures deemed unsafe by code enforcement.
      • Make sure that the incident commander conducts an initial size-up of critical fireground factors before beginning fire fighting efforts and continuously re-views and reevaluates these factors during all fire-ground operations. A 360-degree size-up should be conducted for all abandoned, vacant, or unoccupied structures.
      • Ensure those in charge of fire incidents (e.g., incident commanders, chief officers, safety officers) are fully trained to fulfill their responsibilities and obligations in the execution of their duties.
      • Educate the public on the need to have home fire drills and designated meeting places in the event of an emergency. The location of designated meeting
      • places should be communicated to the fire department as a way to help confirm and verify building occupancy status.

    Incident commanders (IC) and incident safety officers (ISO) should do the following:

    • The IC should conduct an initial size-up of each incident weighing critical fireground factors (i.e., occupancy status; occupant survivability and rescue potential; vacant building markings or indicators; size, construction and use of the building; age and condition of the building; and the location, size, and extent of the fire in the building) against the department’s risk management profile to determine the initial incident strategy (offensive or defensive). The IC should develop an incident action plan before beginning firefighting efforts and continually review and reevaluate the factors and the risk management plan throughout the operation.
    • The IC should use appropriate risk management criteria to decide whether an offensive or defensive strategy should be employed to attack a fire. The IC should attempt to determine whether the building is occupied or not. Signs to look for include vehicles in garage, driveway, or parked nearby; people at windows of apartment or office buildings calling for help indicates the possibility of other occupants as well; time of day; type of occupancy; and reports from occupants who have escaped the burning structure. Reports from neighbors and bystanders may also provide valuable information.
    • The IC should consider the number of fire fighters, the amount and type of apparatus and equipment available, and the stage of the fire when determining the type of fire attack.
    • Follow departmental policies (risk management plans, SOPs/SOGs) for risk management.
    • Establish, clearly mark, and monitor an exterior collapse zone at structure fires where there is a risk of collapse.
    • Use effective and universal evacuation signals when command personnel determine that all fire fighters should be evacuated from a burning building, as well as during the initiation of defensive operations and during overhaul and salvage operations.
