A fire in a three story multiple family apartment building injured four City of Chicago (IL) firefighters when an interior stairway collapsed during firefighting operations.
The building was constructed in 1927 and consisted of 5456 square feet of space with 3-5 apartment units. Built of masonry wall construction with a wood floor joist system, the fire was reported at 8:43 a.m., in the Type III classified occupancy.

The fire began as a basement fire that travelled up two floors, eventually compromising an upper stairway which resulted in compromise and collapsed injuring four Chicago firefighters.
The inherent characteristics of the building and the manner of fire travel and impingement are apparent contributors to the event.

The four firefighters sustained injures during operations when the internal stairwell connecting the second and third floors gave way.
The mayday was transmitted, and a 211 Plan 1 at approximately 09:00 hrs., seventeen minutes into the operation according to published reports issued by Deputy District Chief Lynda Turner. Following the mayday and firefighter removals, defensive operations were initiated.
Two of the firefighters sustained smoke inhalation and two firefighters minor injuries, according to Fire Department officials.
A large warehouse fire in a 211,000 SF complex resulted from from a transformer explosion this morning at the Wix Distribution Center in Gastonia, NC. The building complex was a former textile mill and was built in 1917.
Published report indicate that more than 60 firefighters operated at the scene to control the fire.
It was reported that Fire Chief Phillip Welch stated firefighters started fighting the fires inside the building after the transformer explosion occurred, but it quickly got out of control.“There was an aggressive attack inside, but just because of the storage fight, we were not able to overcome that nor was the sprinkler system,” Welch said.
How prepared is your department for a large scale fire in a large footprint warehouse?
Have you completed pre-fire plans, walk through tours and table top exercises for the key at risk buildings or complexes?
Do you know what the sustained water flow requirements might be for a heavily or fully involved complex or building?
Practices and honed your skills on establishing and managing a complex, multi-operatonal period incident?
Have you looked at creating box alarms or pre-arranged greater alarm response and resource requests?
Have you trained with the departments, jurisdictions and companies that might respond?
Do you have strategies and tactics identified and have you trained on them for operations in large scale buildings? Don’t implment and treat the incident like you would a residential or small commercial fire….
Respect the building and predict with conservative decision-making
Manage and expect compromise and collapse, rapid fire extention and operational challenges to fixed suppression systems and protectivies
Don’t over extend companies while attmtping to operate in the interior: These are typcially closed building ( lack of immedate exiting capabilties) with a special need for air management and accountability and access control.
Fire in Syracuse: Four firefighters LODD: The 701 University Avenue Fire April 9, 1978
April 9th marks the 35th anniversary of the 701 University Ave. fire that claimed the lives of four Syracuse (NY) firefighters in 1978 while conducting search & rescue and suppression operations at an apartment building on the Syracuse University Campus, in Syracuse, New York.
The fire began when one of the tenants lit a candle in a styrofoam wig stand and left it unattended. At 00:46 hours on Sunday April 9, 1978, an alarm of fire was transmitted for a reported building fire at 701 University Avenue on the campus of Syracuse University.
The Victorian style house was a three story building constructed of wood balloon framing and was built circa 1898. The house had been converted into ten (10) apartments that were occupied by SU students. The gross area of each of the three floors was approx. 1,750 sq. ft., with a predominate rectangular footprint shape measuring 69 ft. x 35 ft. The third floor apartments only had access via a stairway in the rear, down a long narrow corridor that measured only 33 inches wide.

The building had inherent vertical and horizontal concealed spaces indicative of balloon frame style construction along with additional concealed spaces in the third floor ceiling area. A partial automatic sprinkler system had been installed in the building in order to comply with a 1952 State of New York law. This system provided protection to the basement, means of egress, a storage area and a portion of the concealed space above the third floor.
The fire originated in a second floor apartment, and then spread into the combustible concealed space above the third floor ceiling. Approximately sixteen minutes into fireground operations the first indications of firefighting personnel being in distress were received. The first call to the Alarm center was made at 0045:17 hrs., with the first-due engine arriving at 0048:05 and first water applied at 0051 (est).
The four SFD fire fighters, Frank Porpiglio Jr., Stanley Duda, Michael Petragnani, and Robert Schuler, who were assigned to the Squad and Rescue Companies, entered the house to conduct a primary search of the premises for SU students thought to be trapped in the house.
While operating on the third floor inside, a scalding steam caused by triggered sprinklers prevented the four firefighters from escaping, and they eventually depleted their air supply and suffocated to death. The firefighters were operating with full PPE that was complaint at that time ( 1978) and were utilizing state-of-the art SCBA in the form of the new 4.5 SCBA systems. All the tenants had escaped safely before the fire fighters had entered the house. The fire was subsequently investigated by the National Fire Protection Association (NFPA) at the request of the City of Syracuse and NFPA Report No. LS-3 was published.

Remembering the Sacrafice: Capt. Broxterman and FF Schira
On Friday, April 4, 2008 at 06:13:02 hours, what began as a routine response for Colerain Township Fire and EMS Engine 102 to investigate a fire alarm activation at 5708 Squirrels nest Lane, Colerain Township, Ohio resulted in the deaths of Colerain Township Captain Robin Broxterman and Firefighter Brian Schira.
Upon their arrival at the scene of the two-story wood framed, residential building working fire conditions existed in the basement. The initial attack team consisted of Broxterman, Schira, and one other firefighter. The team advanced a 1¾-inch attack hose line through the interior of the building for fire control.
Even though, they were provided with some of the most technologically advanced protective clothing for structural firefighting and self-contained breathing apparatus, it appeared that Broxterman and Schira were overwhelmed by severe fire conditions in the basement.
During their attempt to evacuate the building, the main-level family room flooring system in which the two were traveling on collapsed into the basement trapping the firefighters. Eleven minutes elapsed from time of arrival to the catastrophic chain of events.
This is one of those distinctive reports that has influential and critical operational, training and preparedness elements embedded throughout the report.
It’s apparent there continues to be common threads shared by this event from 2008 and other events and incidents in the past five years where a single of multiple firefighters have lost their lives due to similarities in the apparent and common cause deficiencies and short comings identified.
All company and command officers should read and comprehend the lessons learned. Then, take these new found insights and see what the gaps are at the personal level (yours or those you supervise) as well as the shift, group, station, battalion, division or department as a whole.
If there are gaps, then identify a way to implement timely changes as necessary so there are No History Repeating (HRE) events.
The importance of Reading the Building, taking the time to complete the three sixty and being combat ready and “expecting fire”.
Remember their sacrifice, so we can learn.
Past Post on CommandSafety.com with Report Narrative and Incident DetailsHERE
The following factors were believed to have directly contributed to the deaths of Captain Broxterman and Firefighter Schira:
A delayed arrival at the incident scene that allowed the fire to progress significantly;
A failure to adhere to fundamental firefighting practices; and
A failure to abide by fundamental firefighter self-rescue and survival concepts
Although the aforementioned factors were believed to have directly contributed to their deaths, they might have been prevented if:
Some personnel had not been complacent or apathetic in their initial approach to this incident;
Some personnel were in a proper state of mind that made them more observant of their surroundings and indicators;
The initial responding units were provided with all pertinent information in a
timely manner relative to the incident;
Personnel assigned to Engine 102 possessed a comprehensive knowledge of their first-due response area;
A 360-degree size-up of the building accompanied by a risk – benefit analysis
was conducted by the company officer prior to initiating interior fire suppression operations;
Comprehensive standard operating guidelines specifically related to structural
firefighting existed within the department;
The communications system users (on-scene firefighters and those monitoring the incident) weren’t all vying for limited radio air time;
The communications equipment and accessories utilized were more appropriate for the firefighting environment;
Certain tactical-level decisions and actions were based on the specific conditions;
Personnel had initiated fundamental measures to engage in if they were to become disoriented or trapped inside a burning building; and
Issued personal protective equipment was utilized in the correct manner.

On March 14, 2001 the Phoenix (AZ) Fire Department lost firefighter Brett Tarver at the Southwest Supermarket fire.
Remembering Brett Tarver and the Lessons Learned
In that event, it was 5:00 in the afternoon, the grocery store was full of people and fire was extending through the building. Phoenix E14 was assigned to the interior of the structure to complete the search, get any people out, and attempt to confine the rapidly spreading fire to the rear of the structure.
Shortly after completing their primary search of the building the Captain decided it was time to get out. Tarver and the other members of Engine 14 were exiting the building when Tarver and his partner got lost.
Here’s a link to a previous post on Buildingsonfire.com that provides insights and report links that are as pertainent today, as they were in 2001.

Rapid Intervention Team: Are You Ready? Mar 1, 2007 FireEngineering.com By Robert L. Gray; HERE If you were assigned to be a member of a rapid intervention team (RIT) during your next structure fire-or had to command a fireground rescue as a chief officer-are you confident that you would be up to the task of successfully responding to a firefighter Mayday?
The IAFF Fire Ground Survival Program (FGS) is the most comprehensive survival-skills and mayday-prevention program currently available and is open to all members of the fire service. Incorporating federal regulations, proven incident-management best practices and survival techniques from leaders in the field, and real case studies from experienced fire fighters, FGS aims to educate all fire fighters to be prepared if the unfortunate happens.

The program provides participating fire departments with the skills they need to improve situational awareness and prevent a mayday. Topics include:
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.
Fire Fighter Expectations of Command: command-level mayday training, pre-mayday, mayday and rescue, post-rescue, expanding the incident-command system, communications.
Safety – Initial Rapid Intervention Crew (IRIC)
This policy establishes procedures for ensuring the highest level of safety when conducting interior operations in an atmosphere that is Immediately Dangerous to Life and Health (IDLH).
U.S. Firefighter Disorientation Study (1979-2001)
This study was conducted in an effort to stop firefighter fatalities caused by smoke inhalation, burns, and traumatic injuries attributable to disorientation. It focused on 17 incidents occurring between 1979 and 2001 in which disorientation played a major part in 23 firefighter fatalities.
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.”
Understanding the distinctiveness of your first-due, mutual aid or greater-alarm response area requires constant vigilance and continuous observations. Building knowledge equals firefighter safety. Photo By CJ Naum
When we look at various buildings and occupancies, past operations (good and bad) give us experience that defines and determines how we assess, react and expect similar structures and occupancies to perform at a given alarm. The “art and science of firefighting” is predicated on a fundamental understanding of how fire affects a building and its occupants and the manner in which the fire service engages when called on to combat a structure fire.
We have certain expectations that fire will travel in a defined, predictable manner:
That the building will react and perform under assumptions of past performance and outcomes
That fire will hold within a room and compartment for a predictable duration
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 or structural system
That we can safely and effectively mitigate a fire in any given building type and occupancy
That we will have the time to conduct the required tasks identified to be of importance based on identified or assumed indicators
That the building will conform to the rules of firefighting engagement
Times have changed
Today’s incident demands on the fireground are unlike those of even the recent past. This means incident commanders, commanding and company officers and firefighters alike must have increased technical knowledge of building construction with a heightened sensitivity of fire behavior and fire dynamics, a focus on operational structural stability of the compartment and building envelope and considerations related to occupancy risk versus the occupancy type. Understanding the building – its complexities in terms of anatomy, structural systems, materials, configuration, design, layout, systems, methods of construction, engineering and inherent features, limitations, challenges and risks – is fundamental for operational excellence on the fireground and firefighter safety.
There is an immediate need for emerging and operating command and company officers to increase their knowledge and insights of modern building occupancy, building construction and fire protection engineering and to modify traditional and conventional strategic operating profiles in order to safeguard companies, personnel and team compositions. Strategies and tactics 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 and the building that accounts for presumptive fire behavior.
We used to discern with a measured degree of predictability how buildings would perform and fail under most fire conditions. Implementing fundamentals of firefighting operations built on 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 current training programs and academy instruction.
We must maintain a balance with learning about old and new building construction. A renewed focus on Type III, Ordinary /Protected construction and Type IV Heavy Timber must be incorporated within initial, in-service and periodic training and drills. Recent firefighter LODD events in these building types reinforces this need and gap. Photo By CJ Naum
Increasing company and command officer competencies in Building Anatomy, structural systems and how buildings are built and affected by fire behavior is fundamental to effective fireground operations. Interdependent structural components are evident for wall, floor and support assemblies in this Type IV occupancy. Do you know the inherent collapse potential of these buildings? Photo by CJ Naum
We have assumed that the routiness or successes of past operations and incident responses equates with predictability and diminished risk to our firefighting personnel. Photo By CJ Naum
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 these new rules of combat structural fire engagement. Photo by CJ Naum
Executing tactical plans based on faulty or inaccurate strategic insights and indicators has proven to be a common apparent cause in numerous case studies, after-action accounts and firefighter line-of-duty-death reports. Our years of predictable fireground experience have ultimately embedded and clouded our ability to predict, assess, plan and implement Incident Action Plans (IAPs).
The demands of modern firefighting will continue to require the placement of personnel in 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.
Managing Risk
“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 smart aggressive 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.”
Those are the words of Chief Anthony Aiellos (ret.) of the Hackensack, NJ, Fire Department on the 20th anniversary of the Hackensack Ford dealership fire that killed five firefighters in 1988. Without understanding building-occupancy relationships and integrating fire dynamics and fire behavior, risk, analysis, the art and science of firefighting, safety-conscious work environment concepts and effective and well-informed incident management, company-level supervision and task-level competencies, you are derelict and negligent and everyone may not be going home. Empirical insights and test data must be integrated in emerging fire suppression models and improved firefighting theory.
It’s Occupancy Risk versus Occupancy Type; Changes in building size and floor area, compartment volume and interconnectivity, fire load packages, methods and materials in construction and structural support systems create specific risk profiles and demands in what used to be common Occupancy types. A report of a fire in a residential occupancy will have different risks and operational requirements if the house is a 1500 SF Bungalow, a 2500 SF old Decker/Flat or a 4000 SF Engineered system house.

Conclusion
Our world has evolved. Technological and sociological demands create a continuing element of change in the built environment and our infrastructure. With these changes and demands come the need to assess these vulnerabilities, hazards and threats 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.
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.
If the fire service can significantly increase proficiencies in building knowledge and equate that to other fundamental operational aspects in structural fire operations, then there would be a direct enhancement to firefighter safety, through injury and LODD reduction, operational efficiency and operational excellence. If we understand buildings, occupancies and construction, and balance this with our understanding of fire dynamics and orchestrate it with appropriate strategies, tactics and command management, then we made the new safety equation work; Building Knowledge = Firefighter Safety (Bk=F2S). It’s all about the Anatomy of Buildings on fire.
The Probability of Adverse Consequences (PAC) must be recognized in all buildings with continuous and focused risk assessment during all phases and task assignments. This single building and occupancy exemplifies an Integrated Hybrid Building (IHB) type that incorporates Type III Ordinary construction with an engineered wood I-beam roof assembly on the lower street level and Type II non-combustible construction on the upper floors. This would require different IAP’s and tactical deployment in the event of a fire. Photo by CJ Naum
Get out on to your streets and into the field and look at how the buildings are being constructed in your jurisdiction. Understanding how they are built and what the inherent dangers are, coupled with accurate pre-fire planning data will provide mission critical information when engaged in combat fire suppression operations. The anatomy of the building is fundamental to corresponding firefighting operations. Photo by CJ Naum
Understanding Buildings, Performance & Fire Operations
There is an acute corollary of technical knowledge and inter reliance on occupancies, construction, strategy, tactics, risk, safety, physics, engineering and fire suppression theory…FACT!
There are Fundamental Domains that can be applied
There is a direct empirical correlation that provides quantitative & qualitative performance indicators and command gauges that can be utilized for risk assessment and strategic & tactical operational decision-making.
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 or community. Take a good look around and begin to recognize the apparent or subtle changes that will affect and influence your future 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, vent path studies and fire 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. It’s much more than just the Five Fundamental Building Types of the past.
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 time sensitive tactical fire service operations
Think about Adaptive Fireground 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 about that gap?
Understanding the building-occupancy relationships and the art and science of firefighting, equating to Building Knowledge = Firefighter Safety.
Start knowing your buildings-intimately; it’s the key to effective firefighting
Understand the buildings and occupancies not only in your jurisdiction, first or second-due areas, but also in those areas that you may be called upon to respond to for greater alarms or mutual aid. Remember Building Knowledge = Firefighter Safety.
Understand and improve upon your skill set levels and those of your company, battalion, division, department or region.
Keep apprised of different types of building materials and construction used in your community.
The operative question is this: “What do you “really” know about the buildings in your district?”
As you drive about your response district, coming back from an alarm, heading to the firehouse tonight or running errands around your community, take a good look around. Ask yourself 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 may 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?
Never assume the same rules of structural fire engagement can be applied to all buildings without constant risk assessment, recon and situational awareness. Strategies and tactics must remain fluid. This single story commercial occupancy looked like a basic renovated Type III building from the street. An exposed (minimal design) interior accompanied by a non-conventional bow string truss support system and a raftered roof deck are ingredients for catastrophe for the unsuspecting Engine or Truck Companies. Photo by CJ Naum
Keep an eye in the rear view mirror; learning from the wisdom and knowledge from where you’ve been, what you’ve done and all your past experiences and practice; but at the same time focusing on the road before you with keen attentiveness on situational awareness, anticipating error-likely conditions and balanced risk assessment and operational management in both your strategic and tactical deployments.
Ensure you’re glancing occasionally in your rear view mirror to monitor where you’ve been, while driving your initiatives, programs, processes and actions forward. Above all, maintain the courage to be safe and know and understand your buildings, occupancies and your company’s capabilities.
On June 17, 2011, a 22-year-old male paid-on-call fire fighter received fatal injuries when he was struck by bricks and falling debris during an exterior wall collapse at a commercial structure fire.
Crews worked using defensive operations for about 45 minutes attempting to extinguish the fire in the 96 year-old brick and masonry structure that housed an antique store with living quarters located in a rear addition. The victim and another fire fighter were moving a 35-foot aluminum ground ladder away from the Side D (east) wall of the structure when the top part of the exterior wall collapsed. No other fire fighters were injured in the collapse.
96 year-old brick masonry structure degraded by fire burning for over 45 minutes
Fire fighters with limited experience entered collapse zone to move ground ladder
Entering collapse zone in close proximity to master stream directed onto roof
Limited visibility at side and rear of structure may have obscured signs of pending collapse
Limited training on structure collapse hazards.
Key Recommendations
Establish and monitor a collapse zone when conditions indicate the potential for structural collapse
Train all fire fighting personnel on the risks and hazards related to structural collapse
Train on and understand the effects of master streams on structural degradation
Conduct regular mutual aid training with neighboring departments
Designate a staging area for all unassigned fire fighters and apparatus
Implement national fire fighter and fire officer training standards and requirements.
Fire Behavior
According to the investigating State Fire Marshal, the fire originated in the rear of structure due to undetermined causes. A thunderstorm had passed through the area approximately two hours before the fire was reported and lightning strikes were reported in the immediate area. The dispatch center received multiple phone calls reporting a fire behind the antique store near the courthouse square.

Recommendations
Recommendation #1: Fire departments should establish and monitor a collapse zone when conditions indicate the potential for structural collapse.
Discussion: During fire operations, two rules exist about structural collapse: (1) the potential for structural failure always exists during and after a fire, and (2) a collapse danger zone must be established.4-9 A collapse zone is an area around and away from a structure in which debris might land if a structure fails. The collapse zone area should be equal to the height of the building plus an additional allowance for debris scatter and at a minimum should be at least 1½ times the height of the building.
Buildings can collapse due to the structural damage directly caused by a fire, or the activities of fire fighting operations. A fire department’s familiarity with types of construction in their community is an important tool in safely fighting fires. Once a collapse zone is established, fire departments should enforce a “no re-entry” policy unless approved by the Incident Commander.
Fire fighters need to recognize the dangers of operating near parapet walls or underneath overhanging awnings, porches, and other areas susceptible to collapse. Immediate safety precautions must be taken if factors indicate the potential for a building collapse. An external load, such as a parapet wall, steeple, overhanging porch, awning, sign, or large electrical service connections reacting on a wall weakened by fire conditions may cause a wall to collapse. Other factors include fuel loads, damage, renovation work, deterioration caused by the fire as well as pre-existing deterioration, support systems and truss construction.10-12 A collapse is a possibility after fire involvement of more than 10 minutes but fire departments should not rely solely on time as a collapse predictor.11
In this incident, the structure was estimated to be 22 feet high at the top of the D-side wall parapet wall so the collapse zone should have extended at least 33 feet from the structure, covering the entire width of the side-street adjacent to the structure. It is noted that fire fighters were instructed to stay away from the structure and a defensive strategy was used throughout the fire suppression operations. However, a collapse zone was never established or physically identified. Collapse zones can be physically marked by cones, caution tape and other types of physical barriers. Photo 10 taken at the incident scene showed fire fighters standing on the sidewalk as instructed opposite the wall that collapsed.
Recommendation #2: Fire departments should train all fire fighting personnel in the risks and hazards related to structural collapse.
Discussion: Proper training is an important aspect of safe fire ground operation. Both officers and fire fighters need to be aware of different types of building construction and their associated hazards.7,9-10 For example, collapsing roof systems can exert pressure on supporting exterior walls, increasing the potential for wall collapse. Different roof systems may collapse at different rates.11 While heavy timber roof systems will withstand more degradation by fire than lightweight engineered roof trusses, both types are subject to failure.12 Different phases of the fire suppression activities, such as the initial attack, offensive, defensive, and overhaul phases will have different hazards. However, the potential for collapse exists in any fire-damaged structure.11 One source of information related to structural collapse hazards is the National Institute of Standards and Technology, Building and Fire Research Laboratory (NIST / BFRL). A DVD containing videos and reports related to structural collapse can be obtained from the NIST website http://www.bfrl.nist.gov/.13
Establishing priorities is another primary factor in safe fire ground operation that should be included in fire fighter training programs. The protection of life should be the highest goal of the fire service. According to retired Chief Vince Dunn, “When there is no clear danger to civilians, the first priority of firefighting should be the protection of fire fighters’ lives and when no other person’s life is in danger, the life of the fire fighter has a higher priority than fire containment or property consideration.”12 In this incident, there were no indications of civilians in danger inside the structure. It is noted that defensive operations were used throughout the incident.
The Illinois Fire Service Institute (IFSI) coordinates a statewide training program for individuals interested in becoming a fire fighter. This program offers a 24-hour Basic Fire Fighter course as well as Fire Fighter II and Fire Fighter III certification. The IFSI Fire Fighter II certification is roughly equivalent to the National Fire Protection Association (NFPA) Fire Fighter I and IFSI Fire Fighter III is roughly equivalent to NFPA Fire Fighter II as specified in NFPA 1001 Standard for Fire Fighter Professional Qualifications.1 NFPA FF I reflects minimum training standards for a fire fighter who is always working under supervision. NFPA FF II addresses the assumption of command and transfer of command but does not contain specific job performance requirements (JPRs) to illustrate the required skills. The IFSI 24-hour Basic Fire Fighter course may not properly prepare new fire fighters for the hazards associated with structural fire fighting. Many fire fighters, especially in the volunteer ranks, may be called upon to fill company officer and incident commander roles when they may not have received adequate training to prepare them for the additional responsibilities that are required of fireground officers. At a minimum, fire fighters who serve as company officers and who may be expected to serve as the initial incident commander should receive training equivalent to NFPA Fire Fighter II, as defined by NFPA 1001. In this incident, the victim had not completed the minimum IFSI or NFPA training requirements for individuals operating at a structure fire. Also, the two lieutenants who served as incident commanders had not completed training meeting the requirements of NFPA Fire Fighter II as defined by NFPA 1001, which should be the minimum training requirements for a fire fighter operating as a fireground officer.
Recommendation #3: Fire departments should train on and understand the effects of master streams on structural degradation.
Discussion: Master streams are an effective tool for fire suppression operations. Master streams can deliver a large volume of water over a distance while reducing the direct exposure of fire fighters to the fire. Master stream operations can also accelerate structural degradation and can increase the risk of a building collapse.14-16 When multiple master streams are flowing water into a building, the additional weight of the water can rapidly increase the potential for structural collapse. Water weighs 8.33 pounds per gallon. A master stream flowing 1,000 gallons per minute can add an additional 8,330 pounds per minute that the structure, already deteriorated by fire, must support. In 30 minutes, the additional weight contributed by this master stream could add 249,900 pounds or 125 tons of additional weight to the structure.17 Direct impingement of the master stream at close range can also directly contribute to structural degradation by dislodging bricks, breaking windows and other building components. Master streams can also push fire throughout the interior of a structure, leading to fire spread.
Another important indicator that fire fighters and officers should look for is the presence or lack of runoff during master stream operations. If multiple outside streams are being applied to a structure and there is little or no water runoff, the water must be accumulating somewhere.15 As noted above, the additional weight added by standing water on roofs or floors can significantly contribute to the risk of structural collapse. Fire fighters and fire officers need to understand this fact and take this into consideration as part of the Incident Action Plan. If a collapse zone has not already been established, one should be established now. Fire fighters should not be allowed to enter the collapse zone without the direct permission of the Incident Commander.18
Recommendation #4: Fire departments should use risk management principles at all structure fires.
Discussion: While it is recognized that fire fighting is an inherently hazardous occupation, established fire service risk management principles are based on the philosophy that greater risks will be assumed when there are lives to be saved and the level of acceptable risk to fire fighters is much lower when only property is at stake. Interior (inside a structure) offensive fire-fighting operations can increase the risk of traumatic injury and death to fire fighters from structural collapse, burns, and asphyxiation. Established risk management principles suggest that more caution should be exercised in abandoned, vacant, and unoccupied structures and in situations where there is no clear evidence indicating that people are trapped inside a structure and can be saved.19 More importantly, the fire department must establish a standardized method or approach to assess the risks encountered at each incident especially structure fires. Structure fires are very dynamic and fast paced operations with little room for error, mistakes, or miscalculations of the significance of the risk encountered.
The Incident Commander is specifically responsible for managing risk at the incident; however, one person cannot be expected to apply these principles to an incident if the organization has not integrated a standard approach to risk management into its standard operating procedures and its organizational culture. To be effective, risk management principles must be integrated into the entire operational approach of the fire department organization. They must be incorporated within the duties and responsibilities of every officer and member. The single most important reason to establish an effective incident management system is to ensure that operations are conducted safely. Every individual assigned to the incident is responsible for monitoring and evaluating risks and for keeping the Incident Commander informed of any factor that causes the system to become unbalanced. Continuous risk assessment should be reprocessed with every benchmark or task completed until the incident is ended.20
A standardized evaluation of the situation must occur at each incident starting with the first arriving officer or member of the department arriving on scene of the incident. This process starts with the scene size-up. This responsibility starts with the first arriving unit that must look at the entire incident scene versus focusing on a small part of the situation. During the size-up, the Incident Commander must remember the incident prioritizes which are:
Life Safety
Incident Stabilization
Property Conservation
Continuous – fire fighter safety
Situations where there is clear evidence or indication that there is a life safety (imminent rescue or trapped occupants) changes the focus of the strategy and incident action plan. Established risk management principles dictate that more caution is exercised in abandoned, vacant, and unoccupied structures.
Scene size-up should include the following information. Scene size-up should begin at the beginning of the alarm, continue upon arrival on scene, and continue throughout the incident. Some considerations should include:
Life safety/occupied structure and realistic evaluation of occupant survivability and rescue potential
Type of Occupancy and consideration of fire load and fire behavior
Access
Building Construction
Environmental Conditions
Location and extent of the fire within the building
Resources Responding
Water Supply
Special Hazards/Risks
Time of Day
Color of Smoke
Utilities
Exposures affected or potential affected
A realistic evaluation of the ability to conduct an offensive attack with available resources.19,21
The Incident Commander should use the scene size-up to formulate a strategy and the Incident Action Plan. Incident factors and their possible consequences offer the basis for a standard incident management approach. Decisions and the action they produce can be no better than the information on which they are based. A standard information management approach is the launching pad for effective incident decision making and successful operational performance. The IC must develop the habit of using the critical factors in their order of importance as the basis for making the specific assignments that make up the Incident Action Plan (IAP). This standard approach becomes a huge help when it is hard to decide where to start.
The incident scene size-up must be viewed as a 2-part process: 1) determining the conditions of the incident scene, and 2) determining whether the fire department has on scene, has in route, or is in need of additional resources to address the challenge presented by what has been identified during the first part of the size-up process.
The IC must create a standard information system and use effective techniques to keep informed at the incident. Information is continually received and processed so that new decisions can be made and old decisions revised based on increased data and improved information. The IC can never assume action-oriented responders engaged in operational activities will just naturally stop what they are doing so they can feed the IC a continuous supply of top-grade objective information. It is the IC’s responsibility to do whatever is required to stay effectively informed.22
During most critical incident situations, Command many times must develop an IAP, based only on the critical factor evaluation information available at the beginning stage of operations. Many times, that information is incomplete. Even though the IC will continue to improve its quality, the IC will seldom function during the fast, active periods of the event with complete or totally accurate information on all factors.22
This is most evident during confused, compressed-time initial operations. This continual improvement in the accuracy and timeliness of incident information becomes a major IC function. The ability of the IC and the tactical and task level officers to quickly be informed and perform an analysis of the critical factors that can cause major physical and emotional setbacks to the responders and the customers will have a great impact on the health and longevity of the fire fighters, other first responders, the customers and their property.22
In general terms, the risk management plan must consider the following: (1) risk nothing for what is already lost—choose defensive operations; (2) extend limited risk in a calculated way to protect savable property—consider offensive operations; (3) and extend very calculated risk to protect savable lives—consider offensive operations.19,23,24 NFPA 1500 Standard on Fire Department Occupational Safety and Health Program, Chapter 8.3 addresses the use of risk management principles at emergency operations. Chapter 8.3.4 states that risk management principles shall be routinely employed by supervisory personnel at all levels of the incident management system to define the limits of acceptable and unacceptable positions and functions for all members at the incident scene. Chapter 8.3.5 states that at significant incidents and special operations incidents, the Incident Commander shall assign an incident safety officer who has the expertise to evaluate hazards and provide direction with respect to the overall safety of personnel. The annex to Chapter 8.3.5 contains additional information.25
This incident occurred in a structure of mixed occupancy of both commercial and residential use. First arriving crews talked to the building owner and verified that no one was inside the structure. The Incident Commander quickly adopted a defensive strategy and told fire fighters at the front door not to enter the structure. As additional resources arrived on-scene, and Command was passed to higher ranking officers, a defensive operation was maintained. A ground ladder used to ventilate the second story windows on the Side D was left in place where it was last used. Approximately 45 minutes after the first crews arrived on-scene, two fire fighters overheard discussions about the ladder being in a bad location and approached the structure to retrieve the ladder. Given the length of time the fire had been burning, the visual indicators of structural instability (smoke pushing out through cracks in the masonry walls and the sound of bricks popping), the presence of star-shaped anchor plates on the exterior wall and other factors, the best scenario would have been to leave the ladder in place until the area was deemed safe or just write the ladder off. A safer strategy for retrieving the ladder would have been to use a pike pole or other long tool to reach the ladder from a safe distance under the direct observation of other fire fighters monitoring the conditions of the exterior walls. Using a pike pole or other tool to pull the ladder down while standing as far as possible from the exterior wall, may have resulted in a different outcome.
Recommendation #5: Fire Departments should utilize the Incident Command System at all emergency incidents.
Discussion: National Fire Protection Association (NFPA) 1500 Standard on Fire Department Occupational Safety and Health Program, 2007 Edition25 and NFPA 1561 Standard on Emergency Services Incident Management System, 2008 Edition26, both state an incident management system should be utilized at all emergency incidents. Most often, this system is commonly known as or referred to as the Incident Command System (ICS).
The Incident Command System is intended to provide a standard approach to the management of emergency incidents. The many different and complex situations encountered by fire fighters require a considerable amount of judgment in the application of the Incident Command System. The primary objective is always to manage the incident, not to fully implement and utilize the Incident Command System. The Incident Commander should be able to apply the Incident Command System in a manner that supports effective and efficient management of the incident. The use of the Incident Command System should not create additional challenges for the Incident Commander, but rather provide a systems approach to ensuring for a successful outcome of the incident.26
Most incidents are considered routine and involve a small commitment of resources, while few incidents involve large commitments of resources, complex situations, and are low frequency/high risk events. It is imperative that the Incident Command System be able to accommodate all types and sizes of incidents and to provide for a regular process of escalation from the arrival of the first responding resources at a routine incident to the appropriate response for the largest and most complex incidents. The Incident Command System should be applied, even to routine incidents, to allow fire fighters and other first responders to be familiar with the system, prepared for escalation, and aware of the risks that exist at all incidents.26
NFPA 1561, Chapter 3.3.29 defines an incident management system as “A system that defines the roles and responsibilities to be assumed by responders and the standard operating procedures to be used in the management and direction of emergency incidents and other functions.”26 Chapter 4.1 states “The incident management system shall provide structure and coordination to the management of emergency incident operations to provide for the safety and health of emergency services organization (ESO) responders and other persons involved in those activities.”26 Chapter 4.2 states “The incident management system shall integrate risk management into the regular functions of incident command.” 26
The incident management system covers more than just fireground operations. The incident management system must ensure for command and fire fighter safety which includes situational evaluation, strategy and the incident action plan, personnel accountability, risk assessment and continuous evaluation, communications, rapid intervention crews (RIC), roles and responsibilities of the Incident Safety Officer (ISO), and interoperability with multiple agencies (law enforcement, emergency medical services, state and federal government agencies and officials, etc.) and surrounding jurisdictions (automatic aid or mutual aid responders).
One of the most critical components of this system is the development and implementation of an Incident Action Plan (IAP). For the fire service, the majority of times the Incident Action Plan is communicated verbally. The IAP is based on the resources immediately available and those responding. The goal is determined in accordance with the incident priority from which a strategy must emerge; tactical objectives, aimed at meeting the strategy, are determined and specific assignments made. A personnel accountability system should be established as assignments are made. The important point is that the Incident Commander communicates the IAP to tactical and task level supervisors.
Recommendation #6: Fire departments should designate a staging area for all unassigned fire fighters and apparatus.
Discussion: NFPA 1561 Standard on Emergency Services Incident Management System defines staging as a specific emergency management function where resources are assembled in an area at or near the incident scene to await instructions or assignments.26 Staging provides a standard controlled method to keep reserves of responders, apparatus, and other resources ready for action at the scene of the incident or close to the scene of the incident (within two – three minute response times). Staging also provides a standard method to control and record the arrival of apparatus and resources.
When the Incident Commander requests additional resources for an incident, the IC is responsible for designating a staging area. Depending on the size and complexity of an incident, multiple staging areas may be used. This is based on the response route of the resources, to stage resources by typing (e.g. engines, brush trucks, medic units, law enforcement, etc.), or due to location near the incident. The staging area manager documents the available resources. This helps the Incident Commander to keep track of the resources that are on the scene and available for assignment, and to know where they are located and where specific units have been assigned. The Staging Area Manager reports to the IC unless an Operations Section Chief has been assigned, then the Staging Area Manager would report to the Operations Section Chief.
When companies or resources arrive in staging, they report to the Staging Area Manager and stand by for assignment. The Staging Area Manager records and keeps an inventory of all resources and equipment assigned to Staging. A system needs to be in place that details what needs to occur when Staging starts to run low on resources. Staging lets “Command” know when resources are low, and Command orders more resources through Dispatch.
Staging provides an avenue for reducing overall incident communications, and maintaining control of resources throughout the incident operations.
Recommendation #7: Fire departments should conduct pre-incident planning inspections of buildings within their jurisdictions to facilitate development of safe fireground strategies and tactics.
Discussion: National Fire Protection Association (NFPA) 1620 Standard for Pre-Incident Planning, 2010 Edition, states “the pre-incident plan shall provide critical information for responding personnel at the time of dispatch and shall include initial actions based on the priorities of life safety, scene stabilization, and incident mitigation.” This standard also states that “the primary purpose of a pre-incident plan is to help responding personnel effectively manage emergencies with available resources. Pre-incident planning involves evaluating the protection systems, building construction, contents, and operating procedures that can impact emergency operations.”27 A pre-incident plan identifies deviations from normal operations and can be complex and formal, or simply a notation about a particular problem such as the presence of flammable liquids, explosive hazards, modifications to structural building components, or structural damage from a previous fire.7,27-28
In addition, NFPA 1620 outlines the steps involved in developing, maintaining, and using a preincident plan by breaking the incident down into pre-, during- and post-incident phases. In the preincident phase, for example, it covers factors such as physical elements and site considerations, occupant considerations, protection systems and water supplies, hydrant locations, and special hazard considerations. Building characteristics including type of construction, materials used, occupancy, fuel load, roof and floor design, and unusual or distinguishing characteristics should be recorded, shared with other departments who provide mutual aid, and if possible, entered into the dispatcher’s computer so that the information is readily available if an incident is reported at the noted address. Since many fire departments have tens and hundreds of thousands of structures within their jurisdiction, making it impossible to pre-plan them all, priority should be given to those having elevated or unusual fire hazards and life safety considerations.
Pre-plan information should include predicted alarm assignments based upon the fire potential. This will help to ensure that needed resources are dispatched immediately, even if they are some distance away or will provided through mutual aid. If the expected fire potential dictates that 30 fire fighters are needed and the authority having jurisdiction only has 15 fire fighters, the pre-plan should identify the mutual aid resources available to safely and effectively mitigate the expected fire scenario. The pre-plan information should take into consideration the need for incident command and command level officers to fill roles such as safety officer, accountability, tactical level management (i.e. division or group supervisor), RIT / RIC supervision, staging, rehabilitation, IC support ( chief’s aide or staff assistant to monitor radio communications, track crew assignments, resources availability, etc.) and other functions as necessary. When the need for these positions are considered in the pre-planning process, these positions can be rapidly filled throughout the initial alarm assignments, allowing for crew and supervisory integrity while placing more experienced command level support officers in the roles needed to ensure effective supervision and support in the hazard zone. In this incident, pre-planning the structure could have identified the potential collapse hazards associated with the structure due to the age and type of construction, the presence of the star-shaped anchor plates on the exterior walls, and the high fuel load present. It is noted that the Fire Department A had an unwritten policy that any fires in the older commercial structures within the city would be fought defensively.
Recommendation #8: Fire departments should conduct regular mutual aid training with neighboring departments.
Discussion: Although there is no evidence that the following recommendation would have prevented this fatality, it is being provided as a reminder of a good safety practice. Mutual aid companies should train together and not wait until an incident occurs to attempt to integrate the participating departments into a functional team. Differences in equipment and procedures need to be identified and resolved before an emergency occurs when lives may be at stake. Procedures and protocols that are jointly developed, and have the support of the majority of participating departments, will greatly enhance overall safety and efficiency on the fireground. Once methods and procedures are agreed upon, training protocols must be developed and joint-training sessions conducted to relay appropriate information to all affected department members.
Fire departments should develop and establish good working relationships with surrounding departments so that reciprocal assistance and mutual aid is readily available when emergency situations escalate beyond response capabilities. Both fire departments involved in this incident were participating members in the Mutual Aid Box Alarm System (MABAS), a mutual aid system designated to assist with mutual aid response of fire, emergency medical services (EMS), specialized response teams, and station coverage during a state declared disaster or when an incident overwhelms the available resources of a participating community. This incident did not escalate to the size of a MABAS event. Both departments reported that they planned to implement mutual aid training with neighboring departments but had done so on a limited basis up to the time that this incident occurred.
Recommendation # 9: Fire departments should ensure that fire fighters wear a full array of turnout clothing and personal protective equipment (i.e. SCBA and PASS device) appropriate for the assigned task while participating in fire suppression and overhaul activities.
Discussion: Although there is no evidence that the following recommendation would have prevented this fatality, it is being provided as a reminder of a good safety practice. The proper selection and use of personal protective equipment (PPE) is required by OSHA regulations, recommended in NFPA standards, and is good safety practice. Chapter 7.1.1 of NFPA 1500, Fire Department Safety and Health Program, 2007 Edition, 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.” Chapter 7.1.2. states “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.”25 The incident commander should establish the level of protective clothing necessary to enter the fire zones (hot, warm, and cold). The OSHA Respirator Standard Title 29, Code of Federal Regulations (CFR) 1910.134 lists requirements for SCBA use in immediately dangerous to life or health (IDLH) atmospheres.29 While the lack of personal protective equipment (PPE) and clothing did not contribute to the fatality that occurred at this incident, it is generally recognized that SCBA should be worn and used at all times when fire fighters may be exposed to smoke and other hazardous atmospheres. Photos taken during the incident show fire fighters working in close proximity to the burning structure who were not wearing proper respiratory protection (see Photo 7, Photo 8 and Photo 11).
In addition, standard setting organizations, national fire service organizations and other interested parties should:
Recommendation #10: Implement national fire fighter and fire officer training standards and requirements.
Discussion: In 2008, the National Volunteer Fire Council (NVFC) adopted a policy position that all volunteer fire departments should establish a goal to train all personnel to a level consistent with the mission of the fire department, based on the job performance requirements outlined in NFPA 1001: Standard for Fire Fighter Professional Qualifications. The NVFC is committed to ensuring that volunteer firefighters have an appropriate level of training to safely and effectively carry out the functions of the department(s) that they belong to. 30
“The roles and responsibilities of the fire service have evolved over the years. As the breadth and scope of what it means to be a firefighter has expanded, to varying degrees depending on the jurisdiction, the necessity for training within the fire service has grown. Unfortunately, a large number of volunteer fire departments are still operating with personnel who are not trained to a level consistent with national consensus standards for basic firefighter preparedness. This can lead to ineffective and unsafe responses that put lives and property at risk.” 30 This issue actually encompasses the entire fire service and not just the volunteer ranks.
“As the need for proper training has become more urgent, many volunteer fire departments are finding it increasingly difficult to attract new members. The average age of volunteer firefighters has risen steadily over the past two decades, as many young people move out of rural areas and the ones who stay find themselves with less free time to devote to training.” 30
Standard setting organizations, states and authorities having jurisdiction should move to develop national standards so that fire fighters across the United States are trained to the same minimum levels. The Illinois Fire Service Institute (IFSI) coordinates a statewide training program for individuals interested in becoming a fire fighter. This program offers a 24-hour Basic Fire Fighter course as well as Fire Fighter II and Fire Fighter III certification. The IFSI Fire Fighter II certification is roughly equivalent to the National Fire Protection Association (NFPA) Fire Fighter I and IFSI Fire Fighter III is roughly equivalent to NFPA Fire Fighter II as specified in NFPA 1001 Standard for Fire Fighter Professional Qualifications.1 NFPA FF I reflects minimum training standards for a fire fighter who is always working under supervision. NFPA FF II addresses the assumption of command and transfer of command but does not contain specific job performance requirements (JPRs) to illustrate the required skills. The IFSI 24-hour Basic Fire Fighter course may not properly prepare new fire fighters for the hazards associated with structural fire fighting. Many fire fighters, especially in the volunteer ranks, may be called upon to fill company officer and incident commander roles when they may not have received adequate training to prepare them for the additional responsibilities that are required of fireground officers. At a minimum, fire fighters who serve as company officers and who may be expected to serve as the initial incident commander should receive training equivalent to NFPA Fire Fighter II, as defined by NFPA 1001.
Fire department members that are assigned to or assume supervisory positions at an incident scene must have an additional level of competencies that are necessary to ensure for the safety of themselves and the members they supervise while mitigating the hazard encountered. A company officer must have the correct combination of practical experience, training and skill sets that correspond with their job requirements and expected functions in order to execute the expected duties in a safe, effective, efficient and competent manner. The company officer fulfills a mission critical role within the fire service that directly affects department personnel, public safety and community accord. The title carries with it the opportunity to ride the “front seat” and be in charge of directing a company to address incident operations and demands dictated by the company’s function, responsibility, and task assignment. NFPA 1021, Standard on Fire Officer Professional Qualifications provides clear and concise job performance requirements (JPR) that can be used to determine if an individual, when measured to the standard, possess the skills and knowledge to perform as a fire officer.31 Fire departments should ensure that all fire fighters who are expected to perform the duties of a company officer or greater responsibility have the necessary knowledge, experience and receive adequate training equivalent to NFPA Fire Fighter II, as defined by NFPA 1001 and Fire Officer as defined by NFPA 1021.
Operations at 30 Dowling Circle 01.19.2011 Box 11-09
Mark Gray Falkenhan had dedicated his life to serving others. He perished in the line of duty on January 19, 2011 while performing search and rescue operations at a multi-alarm apartment fire in Hillendale, Baltimore County (Maryland). He was 43 years old.
On Wednesday, January 19, 2011, a fire occurred in an apartment building located in the Hillendale section of Baltimore County, Maryland. This fire resulted in the line of duty death (LODD) of volunteer firefighter Mark G. Falkenhan, who was operating as the acting lieutenant on Squad 303 . Upon their arrival, FF Falkenhan and a second firefighter from Squad 303 deployed to the upper floors of the apartment building to conduct search and rescue operations. Other fire department units were already involved with both firefighting operations and effecting rescues of trapped civilians.
During these operations, FF Falkenhan and his partner became trapped in a third floor apartment by rapidly spreading fire and smoke conditions. The second firefighter was able to self-egress the building by diving headfirst down a ladder on the front (address side) of the building. FF Falkenhan declared a “MAYDAY” and implemented “MAYDAY” procedures, but was unable to escape or be rescued.
FF Falkenhan was located and removed via a balcony on the third floor in the rear of the building. Resuscitative efforts began immediately upon removal from the balcony, and continued en route to the hospital. FF Falkenhan succumbed to his injuries and was pronounced deceased at the hospital.
The Baltimore County (MD) Fire Department published the Line of Duty Death Investgation Report of the 30 Dowling Circle Fire recently. The report was written by a Line of Duty Death Investigation Team comprised of departmental members, including representatives of the local firefighters’ union and the Baltimore County Volunteer Firemen’s Association.

The following is and executive narrative of the final report (PDF) on the apartment fire where Volunteer Firefighter Mark Falkenhan sustained fatal injuries. The entire report can be downloaded HERE .
The Baltimore Sun newspaper published an editorial about the death of Firefighter Falkenhan that is required reading; HERE . An excerpt from the editorial reads as follows:
FF Mark Falkenhan
The word “hero” gets used too often to describe the most pedestrian of admirable behaviors, from the star quarterback who marches his team for a winning score to the kid who finds a missing wallet and turns it in. But exceptional bravery, special ability, exceptional deeds and noble qualities — those are what define an authentic hero, and Mr. Falkenhan lacked for none of them.
It was not by accidental circumstance or naiveté that he ended up on the third story of that Hillendale apartment complex in the midst of a fire, searching for missing residents. He knew the risks as well as anyone could. But his selfless desire to help others drove him forward into the flames.
That’s what made him exceptional. That’s why his legacy is important. That’s why the community is in his debt.
Incident Executive Summary
On Wednesday, January 19, 2011, a fire occurred in an apartment building located in the Hillendale section of Baltimore County, Maryland. This fire resulted in the line of duty death (LODD) of volunteer firefighter Mark G. Falkenhan, who was operating as the acting lieutenant on Squad 303 (for purposes of this report, Mark will be referred to as FF Falkenhan). Upon their arrival, FF Falkenhan and a second firefighter (FF # 2) from Squad 303 deployed to the upper floors of the apartment building to conduct search and rescue operations. Other fire department units were already involved with both firefighting operations and effecting rescues of trapped civilians.
During these operations, FF Falkenhan and FF # 2 became trapped in a third floor apartment by rapidly spreading fire and smoke conditions. FF # 2 was able to self-egress the building by diving headfirst down a ladder on the front (address side) of the building. FF Falkenhan declared a “MAYDAY” and implemented “MAYDAY” procedures, but was unable to escape or be rescued. FF Falkenhan was located and removed via a balcony on the third floor in the rear of the building. Resuscitative efforts began immediately upon removal from the balcony, and continued en route to the hospital. FF Falkenhan succumbed to his injuries and was pronounced deceased at the hospital.
Baltimore County Fire Department Standard Operating Procedures, Personnel #16, requires a team to be formed, a detailed investigation to be conducted and a report produced for any incident involving a line of duty life threatening injury or death. The team’s objective is to thoroughly analyze and document all the events leading to the injury or death and to make recommendations aimed at preventing similar occurrences in the future. At a minimum, a Division Chief, the Department’s Health and Safety Officer, a member from the Fire Investigation Division, an IAFF Local 1311 union representative, and the Baltimore County Volunteer Firemen’s Association Vice President of Operations (when a volunteer member is involved) is required (see Acknowledgements section for actual team make-up).
The investigating team examined any and all data available, including independent analysis of the self contained breathing apparatus (SCBA), turnout gear and autopsy report. The Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) produced a fire model to assist with evaluating fire behavior. Multiple site inspections were conducted. Extensive interviews were conducted by the team which also attended those conducted by investigators from the National Institute for Occupational Safety and Health (NIOSH). Photographic and audio transcripts were also thoroughly analyzed. A comprehensive timeline of events was developed. All information used to make decisions regarding recommendations was corroborated by at least two sources.
In fairness to those units involved in this incident, the investigating team had the advantage of examining this incident over the period of several months. Furthermore, given the size and nature of the event, and the fact that arriving crews were met with serious fire conditions and several residents trapped and in immediate danger, all personnel should be commended for their efforts for performing several rescues which prevented an even greater tragedy.
The team did not identify a particular primary reason for FF Falkenhan’s death.
What were identified were many secondary issues involving but not limited to crew integrity, incident command, strategy and tactics, and communications.
These issues are identified and discussed, and recommendations are made in appropriate sections of the report, as well as in a consolidated format in the Report Appendix.
Some of the issues identified in this report may require some type of change to current practices, policies, procedures or equipment. Most, however, do not. Specifically, the analysis and recommendations regarding Incident Command and Strategy and Tactics show that if current policies and procedures are adhered to, the opportunity for catastrophic problems may be reduced.
Mark Falkenhan was a well-respected and experienced firefighter.
He died performing his duties during a very complex incident with severe fire conditions and unique fire behavior coupled with the immediate need to perform multiple rescues of victims in imminent danger.
It would be easy if one particular failure of the system could be identified as the cause of this tragedy.
We could fix it and move on. Unfortunately it is not that simple.
No incident is “routine”. Mark’s death and this report reinforce that fact.
Incident Summary
On Wednesday, January 19, 2011 at 1816 hours, a call was received at the Baltimore County 911 Center from a female occupant at 30 Dowling Circle in the Hillendale section of Baltimore County. The caller stated that her stove was on fire and the fire was spreading to the surrounding cabinets. Fire box 11-09 was dispatched by Baltimore County Fire Dispatch (Dispatch) at 1818 hours consisting of four engine companies, two truck companies, a floodlight unit, and a battalion chief. All units responded on Talkgroup 1-2.
The location, approximately one mile from the first dispatched engine company, is a three story garden-type apartment complex, with brick construction and a composite shingle, truss supported roof. The fire building contained a total of six apartments divided by a common enclosed stairway in the center with one apartment on the left and one to the right of the stairs.
Alpha, Bravo, Charlie, and Delta will be used to designate the clockwise geographic locations of the structure, beginning with Alpha on the address side of the building . Entry is gained through the front split-level stairwell by a common entrance door with individual doors leading to each apartment. Each apartment consists of two bedrooms, a kitchen, bathroom, and a living/dining area. There are sliding doors leading to either a wood joist deck/balcony on the second and third floor apartments, or a concrete patio on the first floor apartments. Utilities consist of gas service to the furnace and hot water heaters located in a utility closet in each apartment, with electric service to the remainder of the appliances, including the stove. Interior walls of the apartments are drywall over wood stud construction.
Floor coverings consist of carpeting over tile and concrete on the terrace/first floor. The second and third floor coverings consist of carpeting covering hardwood floors with a plywood subfloor. Interior doors are hollow wood construction. The door to the common hallway is of solid wood construction. The sliding doors to the deck/patio area are glass.
Building Construction
The development and construction of the Towson Crossing Apartments began in the early 1980’s. The buildings are rated in the existing building code for occupancy as Residential 2 (R2). The building code would describe the construction type as Type III. This construction type includes those buildings where the exterior walls are of non-combustible materials and the interior building elements are of any material permitted by the building code.
Building Construction and Features
The subject apartment building, 30 Dowling Circle, is a three story, middle of the group, apartment building constructed on a reinforced concrete slab. The Alpha and Charlie exterior walls are wood framed construction with brick veneer attached by brick ties. The Bravo and Delta exterior walls are block masonry construction and separate adjoining apartment buildings. The interior partition walls consist of wooden 2″x4″ wall studs covered with sheetrock. Paper faced insulation is found between the exterior walls, ceilings and party-walls that separate the apartments.
The apartment building contains six individual apartment units, which are approximately 1000 square feet in size per apartment unit. Two separate units are located on each floor and consist of two bedrooms, a living area, a dining area, a kitchen, and a bathroom. A utility closet is located in each of the living areas. The closet is located along the Alpha wall, and contains the water heater and furnace.
The building is not equipped with an automatic fire suppression system. Smoke detectors were noted; however, it is unknown if they were operational at the time of the fire. A fire extinguisher was noted on the landing between the second and third floor levels of the building.
Topography
From side Alpha the building has two and a half stories above grade while side Charlie is three stories above grade.
The first floor of the building is approximately five feet below ground level with a 20 foot set back from the apartment building parking lot. Side Charlie of the building is at ground level but slopes upward approximately 8 feet with a set-back of 110 feet from the rear alley.
Roof
The roof is constructed of a lightweight truss assembly consisting of 2″x6″ stringers connected by gusset plates. The truss assembly is covered with 5/8 inch plywood and asphalt shingles.
Floor and Ceiling
The floor assembly consists of 2×10 inch floor joists covered by plywood, wooden tongue and groove planking and finished with carpet. The joists run from Alpha to Charlie and are supported by the interior bearing walls. The kitchen floors in all of the units are covered with vinyl tile.
The ceilings throughout the building are sheetrock nailed to the floor joists of the apartment above with the exception of the third level in which the sheetrock is nailed to the roof joists.
Balconies
The balconies are located on side Charlie of the building. The balconies located on levels two and three consist of 5/4″ deck boards over 2″x10″ wooden joists. The joists are cantilevered off of the floor/ceiling assemblies of levels one and two. The first floor balconies are made of concrete and are at ground level. All balconies are accessible through a single pane sliding glass door located in each apartment.
Incident Overview
The first arriving engine, E-11, was staffed with a Captain, Lieutenant, Driver/Operator, and a Firefighter. Upon arrival at 1820 hours, the Captain gave a brief initial report describing a three story garden apartment with smoke showing from side Alpha: “The Captain of E-11 will have Command and we are initiating an aggressive interior attack with a 1 ¾” hand line”. Command also instructed the second due engine to bring him a supply line from the hydrant.
A female resident (victim # 1) appeared in a third floor apartment window, Alpha/Bravo side (Apt. B-1), yelled for assistance, and threatened to jump. Smoke or fire was visible from any of the third floor windows. At 1823 hours, Command advised Dispatch that he had a rescue and that he was establishing Limited Command. Fire Dispatch was in the process of upgrading the response profile to an apartment fire with rescue when the responding Battalion Chief requested that the fire box be upgraded to a fire rescue box. While the Firefighter and Lieutenant prepared for entry into the building, the Captain and Driver/Operator extended a ladder to the 3rd floor apartment window and rescued the resident. The first attempt by the Firefighter and Lieutenant to make entry into the side Alpha entrance was unsuccessful due to the extreme heat and smoke conditions.
Initial Arrival Conditions
The second due engine, E-10, arrived at 1823 with staffing of a Captain, Lieutenant, Driver/Operator, and a Firefighter. At 1823, E-10’s crew brought a 4″ supply line to E-11 from the hydrant at Deanwood Rd. and Dowling Circle and assisted the first-in crew with fire attack.
The Captain from E-10 conferred with Command and was instructed to advance a second 1 ¾” hand line.
The window to the first floor right apartment (Apt. T-2) was removed, and the second 1 ¾” line was advanced to the building by the crew of E-10.
Fire attack was initiated through the removed window. At 1827, Command requested a second alarm.
At this time, heat and smoke conditions just inside the front door improved enough to allow the Firefighter and Lieutenant from E-11 to make entry through the front door and into the stairwell. There they encountered heavy, thick black
smoke and high heat conditions coming up the stairs from the terrace level apartment. The Lieutenant reported that the doorway to the first floor apartment was orange with fire and he had to fight his way through heavy heat and smoke conditions to attack the fire in the first floor right apartment (Apt. T-2). Entry was made approximately 3 feet into the doorway when the Firefighter’s low air alarm began to sound, and he exited the building. A member from E-10’s crew replaced the Firefighter from E-11 on the hose line.
At the same time, the Captain from E-11 proceeded to the rear of the structure to complete his initial 360 degree size up. He noted that there was fire emanating from the open sliding doors on the first floor Charlie/Delta apartment (Apt. T-2), extending to the balcony above. E-1, staffed by a Captain, Driver/Operator, and two Firefighters arrived and completed the hookup of the supply line that had been laid to the hydrant by E-10. The rest of Engine 1’s crew grabbed tools and an extension ladder and reported to the Charlie side of the building.
Personnel stated that at this point fire conditions seemed to improve, suggesting that crews were making progress extinguishing the fire. (The first arriving attack crew reported that they were able to see apparatus lights through the sliding doors on Charlie side, which indicated to them that smoke and fire conditions were improving.)
Truck 1, a tiller unit staffed by a Lieutenant, two Driver/Operators, and a Firefighter, arrived on side Alpha and immediately began search and rescue operations. Windows on the second floor Alpha/Delta side apartment (Apt. A-2) were vented and ladders were thrown to gain access. T-8 arrived at the alley on side Charlie. E-1 extended a ground ladder to the third floor balcony on the Charlie/Bravo side of the structure (Apt. B-1), and made access to the apartment to search for additional victims.
They noted fire venting from the first floor Charlie/Delta apartment (Apt. T-2) out of the sliding glass doors progressing upwards towards the balcony on the second floor. Upon entering the apartment, they conducted a primary search and noted minimal heat with light smoke conditions.
The crew accessed the hallway via the apartment entry door and noticed an increase in the temperature and the amount of smoke.
They immediately closed the door and exited the apartment via the ground ladder.
Upon exiting the apartment, E-1’s crew observed E-292 on the scene with a hand line extending into the apartment of origin, (first floor, Charlie/Delta side, Apt. T-2). The officer on E-1 noted white smoke coming from the unit.
Having already laid a supply line from the intersection of the alley and Deanwood Road, E-292’s crew extended a 1 ¾” hand line into the apartment of origin. Moderate fire conditions with zero visibility were encountered, and they reported feeling a great deal of heat on their knees as they crawled through the apartment.
The Lieutenant and the Firefighter from Truck-1 entered Apartment A-2 via a second floor bedroom window (Alpha/Delta side) and began a search for additional victims. As they traversed the living room area they found an unconscious male resident (victim #2). At 1836 hours, the Lieutenant notified Command via an urgent transmission that a victim had been located and they needed assistance with evacuation. The Lieutenant and Firefighter noted a small fire in the rear corner near the victim as they exited the room. The crew returned to the bedroom from which they had entered and closed the door behind them. Victim #2 was then evacuated from the apartment via a ground ladder through the bedroom window, and transferred to EMS personnel on side Alpha.
Preflashover conditions Alpha Side 18:37 hours
At 1831 hours, Squad 303, a unit staffed by a Driver/Operator, Firefighter Falkenhan (acting Officer in Charge), and 3 other Firefighters had arrived at the Alpha side of the building. Firefighter Falkenhan and two crew members grabbed their tools and immediately entered the building. One Firefighter (Firefighter #1) proceeded to the terrace floor apartment to assist crews with fire attack. Firefighter Falkenhan and the other Firefighter (Firefighter #2) proceeded to the second floor
Bravo side apartment (Apt. A-1) to search for additional victims. They forced the door to the second floor apartment and conducted their search. Finding no one, they reported to Command that they had encountered high heat in the apartment and at 1838 hours, inquired as to which apartment victim #2 had been found. Firefighter Falkenhan advised Command that he and his fellow Firefighter were proceeding to the third floor to continue their search.
At 1840 hours, Battalion Chief 11 (BC-11) arrived on the scene, performed a face-to-face pass on with the Captain on Engine 11, and assumed Command. BC-11 initially observed limited smoke conditions, indicating to him that crews had made progress in extinguishing the fire.
18:41 hours
Meanwhile, the Lieutenant and Firefighter from T-8 entered the second floor apartment that S-303 had just searched (Apt. A-1, second floor, Bravo side). They proceeded through the apartment and went across the hallway to Apartment A-2 where Truck-1 had just made their rescue (second floor, Delta side).
The Lieutenant noted smoky conditions, and saw that the sliding doors to the rear of the apartment were open, and saw a small fire in the rear of the apartment to the left of the open doors. On their way back to their point of entry, T-8’s crew discovered an unconscious female victim (victim #3). At 1837 hours, T-8 attempted to reach Command via radio and was covered by inaudible radio traffic. Dispatch was able to receive the radio transmission from T-8, and advised Command that another victim had been located on the second floor.
At this point, the crew from S-303 had completed their search of the third floor Bravo side apartment (Apt. B-1).
Firefighter Falkenhan and Firefighter #2 were able to look out of the sliding doors on side Charlie down to the first floor apartment, Apt. T-2 (Charlie/Delta side) and could see fire.
Smoke conditions on the third floor were light enough to walk upright in a somewhat crouched position.
The crew returned to the hallway, forced open the door to the third floor Charlie/Delta side apartment, Apt. B-2, and made entry.
Firefighter #2 walked down the hallway to the bedroom on the right while Firefighter Falkenhan searched to the left. After checking the bedroom, Firefighter #2 stated that he heard something behind him and turned to see fire in the hallway.
As the crew from S-303 searched the third floor Delta side apartment (Apt. B-2), The Lieutenant and Firefighter from T-8 were attempting to remove victim #3 from the second floor Delta side apartment (Apt. A-2). As they prepared to move their patient, fire conditions changed suddenly.
The Lieutenant from T-8 observed fire, “…rolling over our heads and out of the apartment door.” An immediate increase in heat conditions was noted. Upon exiting the apartment, T-8’s crew described a “tunnel of fire” coming out of the apartment and into the hallway. At 1841 hours, a radio transmission was made by an unknown source that heavy fire was observed in the hallway through a window at the stairwell landing.
At the same time, (1841) one minute after his arrival, Battalion Chief-11 (Command) noted heavy black smoke coming from the building and observed a “flash” through a second floor window. Command immediately ordered an evacuation of the building. Dispatch sounded the evacuation tones over the radio, and repeated the order to evacuate. Engines on the scene sounded their air horns to indicate that the order to evacuate had been given.
Firefighter #2 from S-303 reported hearing the engines on the fire ground sound their air horns, indicating to him that he needed to leave the building. Smoke conditions in the apartment had changed to thick black smoke, and the fire intensified, blocking his means of egress from the bedroom.
Realizing that he needed to get out of the apartment quickly, Firefighter#2 crawled to a window on the Alpha side of the bedroom and signaled Firefighters below with his hand light to move a ladder to the window. Crews immediately moved the ladder, and at 1841, Firefighter#2 dove headfirst out of the window and down the ladder, where he was assisted by crews working on the exterior of the building.
At 1841, Firefighter Falkenhan declared, “Emergency” on his radio, and repeated the same seven seconds later.
Command immediately queried S-303 for his location and the transmission “I’m down to the floor, heavy fire” was heard. At 1842 hours, Dispatch sounded emergency tones and restricted the Talkgroup to communications only between S-303 and Command.
Seconds later Firefighter Falkenhan again keyed up his portable radio and advised “…trapped on the 3rd floor, heavy fire on the Alpha/Bravo.”
Fourteen seconds later he advised “I hear crew members, the third, MAYDAY, MAYDAY, MAYDAY.”
Command notified Dispatch, “We have a MAYDAY” and was interrupted by a transmission from Firefighter Falkenhan, “urgent.”
Command made several attempts to contact Falkenhan to ascertain his location and determine resources needed (Location Unit Name Assignment Resources) for rescue.
Upon hearing the MAYDAY, crews on side Charlie threw multiple ladders to the third floor balcony to assist with rescue.
Heavy heat, smoke, and fire conditions made rescue difficult, but Firefighter Falkenhan was located and removed from the apartment via the balcony to the extended aerial ladder from T-8. He was unconscious and unresponsive at this time. Resuscitative efforts began immediately upon removal from the balcony, and continued enroute to the hospital. Firefighter Falkenhan succumbed to his injuries and was pronounced deceased at the hospital.
Consolidated List of Recommendations
Crew Integrity
1. Company officers shall ensure that crew integrity is maintained at all times by all personnel operating in an IDLH environment. 2. No personnel shall operate in an IDLH environment without a portable radio.
MAYDAY
1. If possible, the firefighter should activate his/her Emergency button on the portable radio. 2. Once personnel have called a MAYDAY and provided the information needed (LUNAR), they will activate their PASS Device manually and intermittently.
Incident Command
1. Tactical Operations Manual 07 allows Incident Commanders the flexibility to adapt to fast-moving and complex incidents. When re-assuming command, the IC must be identified (verbally through Fire Dispatch) to allow units involved and responding to know who is in command.
2. Incident Commanders must understand that an early initial 360° would give the IC the information needed to develop effective strategy and tactics for incident mitigation.
3. Additional arriving units must give the IC an updated report on fire conditions when noticeably different than those announced in the Brief Initial Report.
4. Arriving units should prompt the IC to assign them supervision of a division when conditions warrant such action.
5. The IC must ensure that all division and group supervisors are properly deployed and verbalize same on the radio for Dispatch and units involved on the incident.
6. Reinforce the importance of the ICS and its functional components for all officers.
7. Ensure a manageable span-of-control is maintained throughout the incident.
8. Evaluate the efficiency of command and control as incidents escalate.
9. A Rapid Intervention Team is a vitally important part of the ICS and its assignment should not be overlooked.
Strategy and Tactics
1. Use caution when passing a hydrant that is in your direction of travel and close to the fire building in an attempt to get a closer one.
2. Consider having the initial backup line proceeding into the same point of entry as the initial crew operating in the IDLH environment. Doing this allows for the line to also aid in protecting the common stairwell (i.e. fire extension/protection for egress). Deploy a third line if needed into another point of access.
3. Consider dialing nozzles up to higher gallons per minute for large structures such as apartment buildings.
4. Consider utilizing a 2-1/2″ attack line for fire attack.
5. The current SOP should be modified to state that when the initial Incident Commander feels that the incident has stabilized to a point where there is no longer a need for him/her to be directly involved with incident operations, a notification through Dispatch shall be made to inform crews on and en route to the scene.
6. The Department should develop training to ensure that Incident Commanders relay changes in modes of operations.
7. Consider attacking fires from other sides of the structure that are on grade.
8. Consider the use of “door control” for protection during search and rescue and exposure protection
9. When deviations to initial orders are made, they must be communicated to Command.
10. IC should consider setting up a division supervisor with the first arriving officer to balance his/her span-of-control early into the incident.
11. Command should initiate group and division supervisors early into an incident and use them to reduce his/her span-of-control. Communicate Conditions, Actions, Needs (CAN) reports early and often.
12. When units are the initial crews deployed to a geographic location, consideration should be given to “prompt” Command to make them a division supervisor (in the absence of direction from Command).
13. Units should request resources, or supply their own as necessary to support the operations that they are undertaking.
14. When given a division assignment, “step back” to take in the overall picture and communicate progress reports to Command.
15. Be clear and concise when setting up division assignments.
16. Utilize the division supervisors for incident operations once assigned.
17. Training on effective use of interior doors to control fire spread should be promoted throughout the department.
18. Consider removing common stairwell windows earlier in fire ground operations when appropriate.
19. While performing operations above the fire, notify Command of changing conditions and immediately request resources to support your function.
20. Set up a command post as early as possible to aid in deploying and accounting for resources as they arrive on the fire ground.
21. Notify Command when entering an IDLH.
22. Request resources to support functions.
23. Set up divisions and groups early to aid in managing the strategic priorities.
24. Be clear in communicating strategy and tactics to companies involved in operations.
25. Command should make it a priority to deploy attack lines on all floors to support the operations of crews working in the area.
Communications
1. A rubberized cover for the radio speaker microphone should be tested by communications and field personnel. This device will cover the push-to-talk (PTT) button and will increase the pressure required for activation. If proved effective, this cover will decrease the likelihood of an accidental activation of the PTT button during vigorous fire ground activity.
2. Continuing study should occur to evaluate methods to control inadvertent radio interference from all units (on the scene, responding, or monitoring) during incident operations. Review PTT logs to identify sources of communications interference.
3. As a result of the investigation, PTT log files will now be saved for 25 days.
4. Fire Communications and field personnel will develop and distribute a mandatory training program outlining proper radio procedures including the importance of radio discipline, MAYDAY procedures, and the procedure for establishing a Command restricted talk group during critical operations.
5. All personnel engaged in operations in an environment immediately dangerous to life and health shall carry a portable radio.
6. The aforementioned mandatory training program shall stress the importance of giving regular updates to Command regarding the extent and location of the fire and other pertinent information.
USFA Releases Civilian Fire Fatalities in Residential Buildings (2008-2010) Report “Other unintentionally set, careless” actions and “smoking” are the leading causes
The Federal Emergency Management Agency’s (FEMA) United States Fire Administration (USFA) issued a special report today examining the characteristics of civilian fire fatalities in residential buildings. The report, Civilian Fire Fatalities in Residential Buildings (2008-2010) was developed by USFA’s National Fire Data Center and is based on 2008 to 2010 data from the National Fire Incident Reporting System (NFIRS).
According to the report:
Ninety-two percent of all civilian fatalities in residential building fires involve thermal burns and smoke inhalation.
The leading specific location where civilian fire fatalities occur in residential buildings is the bedroom (55 percent).
Fifty percent of civilian fire fatalities in residential buildings occur between the hours of 10 p.m. and 6 a.m. This period also accounts for 47 percent of fatal fires.
Thirty-six percent of fire victims in residential buildings were trying to escape at the time of their deaths; an additional 35 percent were sleeping.
“Other unintentionally set, careless” actions and “smoking” (each accounting for 16 percent) are the leading causes of fatal residential building fires.
Approximately 44 percent of civilian fatalities in residential building fires are between the ages of 40 and 69.
Thirteen percent of the fire fatalities in residential buildings were less than 10 years old.
Civilian Fire Fatalities in Residential Buildings (2008-2010) is part of the Topical Fire Report Series. Topical reports explore facets of the U.S. fire problem as depicted through data collected in NFIRS.
Each topical report briefly addresses the nature of the specific fire or fire-related topic, highlights important findings from the data, and may suggest other resources to consider for further information. Also included are recent examples of fire incidents that demonstrate some of the issues addressed in the report or that put the report topic in context.
This report provides a statistical overview of fires in the United States and is designed to equip the fire service and others with information that motivates corrective action, sets priorities, targets specific fire programs, serves as a model for State and local analyses of fire data, and provides a baseline for evaluating programs.

This supplements the continuing research and effort by UL, NIST and numerous other academic and research institutions. From Fire.gov. http://www.nist.gov/fire/collapse.cfm
Structural Collapse Fire Tests: Single Story, Wood Frame Structures
A series of fire tests was conducted in Phoenix, Arizona to collect data for a project examining the feasibility of predicting structural collapse. The fire test scenario was selected as part of a training video being prepared by the Phoenix, Arizona Fire Department. Multiple fires were started in each structure to facilitate collapse; the fires were not intended to test the fire endurance of the structures. Four structures with different roof constructions were used for the fire tests. Temperatures were measured as a function of time in four locations within each structure. Furniture items were placed in the front and back of each structure to simulate living room and bedroom areas. The living room and bedroom areas of each structure were ignited simultaneously using electric matches. Peak temperatures obtained during the tests ranged from approximately 800 °C (1500 °F) to 1000 °C (1800 °F). The roof of each structure collapsed approximately 17 minutes after ignition. In addition to the full scale tests, the plywood and oriented strand board (OSB) roofing materials were tested using a cone calorimeter to characterize the fire properties of the materials.
Structural Collapse Fire Tests: Single Story, Ordinary Construction Warehouse
Two fire tests were conducted in a warehouse located in Phoenix, Arizona to develop data for evaluation of a methodology for predicting structural collapse. A firewall was constructed to divide the warehouse into two fire compartments. Temperatures were measured as a function of time in three locations during the first test and in two locations during the second test. In addition, the volume fraction of carbon monoxide was measured at selected locations during each test. Stacks of wood pallets were used as the primary fuel source and were ignited using paper and an electric match. Some combustible debris and the building structural elements provided the remainder of the fuel load. Peak temperatures obtained at different elevations ranged from approximately 300 °C (570 °F) to 800 °C (1470 °F). Peak carbon monoxide volume fraction reached 4 % in the first test and 5 % during the second test. The roof of the front half of the structure burned through approximately 18 min after ignition of the fire for the first test. The roof of the back half of the structure burned through about 15 min after the start of the second test.
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.
A field-based monitoring technique that utilizes measurements of fire-induced vibration was developed and first demonstrated under a previously funded research effort. This report details the findings of the ensuing 3-year endeavor in which significant improvements were made to both field-test and analysis procedures. A real-time monitoring tool has been developed and numerous full-scale burn tests on a variety of structures have been completed. A significant contribution of the research stems from the use of system stability theory to aid in the interpretation of the field measurements. The techniques described in this report can be used to monitor burning structures and to provide visual indicators that track changes in structural stability.

Residential Fire in Prince George’s County (MD) Injures Seven Firefighters: Wind Driven Conditions Suspected
Apparent wind driven condition contributed to rapidly escalating fire conditions resulting in extreme fire behavior during initial fire suppression operations being coordinated at a single family residential dwelling (SFD) fire Friday night February 24th in Riverdale, MD. At 9:11 p.m. firefighters responded to a house fire in the 6404 57th Avenue, according to published reports and the new release from Prince George’s County (MD) Firefighters.
PGFD companies arrived to find a one-story with basement, single-family home with fire on both levels. A review of public records indicates the SFD was built in 1967 of dimensioned wood frame construction consisting of a single story with a full basement with 780 square feet of occupied floor space. The house foot print was approximately 30 feet x 26 feet and had a low profile gable roof. A review of building (birdseye view) aerial images suggests that a moderate grade change from the Alpha division to the Charlie division is apparent with walk-in basement access.
Street View A-D. Screencapture Googlemaps
Firefighters initiated an interior attack from the Alpha Division when an apparent sudden rush of air fanned by high winds entered from the rear of the house (Delta Division), either from a door or window being opened or broken out, the news release said.
The rapid influx of air from the sustained winds into the interior room compartments combined with the already progressing fire conditions creating a “fire ball’ within the structure’s interior rooms where companies were operating engulfing the firefighters. Firefighters tried to escape and commanders immediately called for an EMS Task Force and Fire Task Force.
A review of internet published archival weather data for the general area (Riverdale/College Park, MD) during the period of 20:55 hrs. and 21:15 hrs., recorded wind speeds of 13.8 – 20.7 MPH with wind gusts of 27.6 – 36.8 MPH. gusts of MPH. (wunderground.com HERE)
At this time two firefighters, Bladensburg Volunteer Fire Fighters Ethan Sorrell and Kevin O’Toole remain in critical condition at Washington Hospital Center. A third fire fighter, Riverdale Volunteer, Michael McLary also remains hospitalized for injuries. Four other injured fire fighters, three from Riverdale and one from College Park, were released and sent home last night according to the latest reports.

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.
Fire Fighting Tactics Under Wind Driven Conditions Report, HERE
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

Fire Fighting Tactics Under Wind Driven Conditions Report, HERE
From Statter911: Here’s what Chief Bashoor told The Washington Post’s J. Freedom du Lac about the fire:
Strong winds were gusting out of the west at the time — “up to 40, 45 mph,” said the chief. They were blowing directly at — and into — the burning basement, which had a west-facing door.
“As soon as the guys opened the front door and advanced, it blew from the basement, up the steps and right out the front door,” Bashoor said. “It was like a blowtorch coming up the steps and out the door.”
The entire incident — “from the time they were in the door until they were burned” — took eight seconds, the chief said.
The firefighters inside the house “did everything they were trained to do,” he said, but they were essentially defenseless.
“Without that wind, the hot air and gases would have been venting out of the rear of the house,” he said. “The current of air essentially produced a chimney right up the steps and out the front door.”
Take a moment to look back at an incident: On December 18, 1998, Three FDNY Firefighters died in-the line of duty while conducting suppression and rescue operations at fire on the tenth floor of 10-story high-rise apartment building for the elderly. At 0454 hours Brooklyn transmitted box 4080 for a top floor fire at 17 Vandalia Avenue in the Starrett City development complex. The sprawling complex is located on Brooklyn’s south shore in the Spring Creek section. The 10 story 50 x 200 fireproof building is used as a senior citizen’s residence. Engine 257 and ladder 170, both quartered in Canarsie, were assigned 1st due and arrived within 4 minutes. By that time the fire already could be seen blowing through two windows. Second and 3rd alarms were quickly transmitted.
As the 1st due Ladder Company, L170′s duty is to search the fire floor. Lieutenant Joseph Cavalieri, and fire fighters Christopher Bopp and James Bohan ascended 10 flights of stairs with extinguishers and forcible entry tools. Their mission was to rescue the resident of apartment 10-D who was believed trapped inside.
NIOSH INVESIGATIVE REPORT SUMMARY (F99-01) On December 18, 1998, several fire companies and fire fighters responded at 0454 hours to a reported fire on the tenth floor of a 10-story high-rise apartment building for the elderly. The fire had been burning for 20 to 30 minutes before it was called in because the resident attempted to put the fire out with small pans of water. As the fire fighters approached the building from the rear, an orange glow was observed in the window of Apartment 10D. As the fire fighters were arriving in front of the high-rise, a call was received from Central Dispatch that a female resident in the apartment next door to the fire apartment was trapped in her apartment and needed help. Several fire fighters entered the lobby area, and some took the stairs to the ninth floor, while others took the elevator to the ninth floor. A Lieutenant and two fire fighters on Ladder 170 (the victims), along with the Lieutenant on Engine 290, took the B-stairs from the ninth floor to the tenth floor, and entered the hallway, in search of the fire, while 4 fire fighters on Engine 290 were flaking out the hose line on the ninth floor and in the stairwell between the ninth and tenth floor in preparation for hookup.
During this same time period, other fire fighters had gone to the tenth floor A-stairwell landing to attempt a hose line hookup to the standpipe in the landing. Engine Company 257 fire fighters, who were attempting to make a hook-up on the fire floor landing, experienced trouble with the heat, heavy smoke, and heavy insulation on the standpipe and were forced to abandon this hook-up. The Lieutenant on Engine 290 and the victims, who were on the B-side, were approaching the center smoke doors (see diagram), when the Lieutenant radioed his driver on the outside, and asked, “Where is the fire?”
The driver radioed back, the fire is in the rear, towards exposure 4. The Lieutenant on Engine 290 then left the tenth floor, descended the stairs to the ninth floor and helped his men drag the hose to the A-stairwell, where they met up with fire fighters on Engine 257, who assisted them in stretching their line and hook-up on the ninth floor. The victims proceeded through the center smoke doors in search of the fire. From the information obtained during this investigation, it is believed the victims found the fire apartment, with the door partially opened, allowing smoke and hot gases to enter the hallway. They then opened the door fully, the wind pushed the fire and extreme heat in the apartment into the hallway, and a flashover occurred, exposing the victims to extreme radiant heat that potentially elevated their body core temperature.
The last radio transmission from the victims was a Mayday call. When the victims were found, all were unresponsive, they were treated at the scene and taken to the hospital where they were pronounced dead by the attending physician.

Take the time to remember FDNY Lt. Joseph Cavaleiri, FF Christopher Bopp and Firefighter James Bohan from Ladder 170
State investigators have cited the San Francisco Fire Department for “serious” worker safety violations in the deaths of two firefighters killed battling a Diamond Heights house fire in June. Reports were published in the San Francisco Chronical, HERE and HERE.
Firefighters lost track of Lt. Vincent Perez, 48, and firefighter-paramedic Anthony Valerio, 53, after they went into the four-level home at 133 Berkeley Way on June 2 and failed to respond quickly to the men’s last radio communication, investigators with the state Department of Industrial Relations’ Division of Occupational Safety and Health said in a report issued Monday.
In recommending that the Fire Department be fined $21,000, the state investigators also said the department had violated state rules requiring that two firefighters be designated outside to assist any two firefighters who venture into a life-threatening environment.
Only one firefighter from Perez and Valerio’s engine company – the first on the scene – was available to come to their help during the blaze, the investigation found.
The state also cited the Fire Department for an incident – evidently before the fatal flareup – in which an unidentified battalion chief ventured into the burning building alone, without keeping in contact with Perez and Valerio. That was also deemed a serious violation of safety rules.
“These are serious in that they had protocols in place, but they weren’t following them,” said Erika Monterroza, spokeswoman for the worker safety agency. “There’s no question that a lack of communications was a big issue here. The investigator found there was a breakdown there.”
Fire Chief Joanne Hayes-White said the department would appeal the findings. She said state officials have told her commanders that the violations fell short of finding the department’s actions responsible for the two firefighters’ deaths. “None of the citations involved a direct cause of the line-of-duty deaths,” Hayes-White said. Monterroza confirmed that, saying the exact circumstances of the firefighters’ deaths could not be determined.
Valerio, Perez and a third member of Engine Company 26 in Diamond Heights were the first firefighters to arrive at the mid-morning blaze, which started when a sparking electrical outlet set curtains on fire.
The third firefighter manned the pumper hose while Valerio and Perez went inside to fight the fire, but the safety regulations require a fourth firefighter to be available outside to assist.
A scene commander, identified by firefighters as Battalion Chief Thomas Abbott, ordered a crew from Engine Company 24 to back up Valerio and Perez inside the building. For several minutes, however, scene commanders tried to find the Engine 26 firefighters, without success.
There was an unspecified gap between that last communication and any effort by firefighters to respond over the radio or track down the men, the state investigation found.
The reports goes on to state that Hayes-White said the department’s investigative report – still in draft form – concluded that the fire had melted one of the firefighters’ microphone cords, cutting off communications. She said any delay in firefighters’ response would be addressed in the final report.
Firefighters ultimately found Perez and Valerio in a landing area and carried the injured men outside. Perez was pronounced dead at San Francisco General Hospital, and Valerio died there two days later.
The state probe also faulted the actions of the unnamed battalion chief who went into the building “alone and also did not remain in contact with the firefighters who were inside.”
Hayes-White said the battalion chief had gone inside only briefly, had seen Perez and Valerio alive and had never been out of other firefighters’ view.
Today December 3, 2011 marks the 12th 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.

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.
From last year’s posting and links here at CommandSafety.com: HERE
A video clip of a structure fire occurring in a single family residential occupancy shows, in the first few frames a back draft occurring per-arrival of fire services. It’s apparent there is a developing and progressing fire in the Charlie division which may have originated in the, or vicinity of the detached garage (B-C) which had a breezeway connected to the main house.

Pre-arrival fire conditions exhibit indicators that suggest the need for the rapid intervention of arriving companies and a coordinated aggressive posture tactically if the incident action plan is formulated to achieve an interior attack. Given the scenario of the backdraft conditions, the likelihood for a degraded or compromised ceiling membrane enclosure (intact ceilings, thus limiting fire extension) being present will hamper and may be an operational concern for interior operating companies as fire conditions continue to grow in magnitude and severity and full extend and take command of the truss loft enclosure.
These fire conditions will extend into the space, resulting in degradation of the structural components and roof assembly-which will present a high risk potential for isolated or catastrophic collapse. This intrusion into the truss loft would require interior operating company officers to maintain attentiveness towards the effectiveness and progress of tactical suppression and support tasks with the potential for fire quickly dropping into operating areas and affecting firefighter safety.
Coordinated and timely vertical ventilation and roof work may be warranted if part of the normal operating parameters of the fire service agencies. In some areas of the county, vertical ventilation is not considered a tactical functional objective and is not implemented.
Adequate fire flow for suppression must be established early on in the operations, if an interior attack is implemented. Projected fire intensity and severity may challenge initial engine companies if hand lines and fire flow rates and the placement of hose streams are ineffective or marginal. In the event of master stream operations it would be crucial to ensure interior fire suppression operations are suspended, a transition to a defensive mode is communicated and acknowledge on the fireground with collapse zone considerations.
Operational Considerations
In viewing the video of pre-arrival conditions and fire parameters and indicators; as an arriving company officer or commanding officer, how would you establish your incident action plan (IAP) and establish operations? Present and discuss why you would make these decisions, what is/are the basis?
What would you be considering in the areas of:
Building Integrity
Collapse Potential
Interior Fire Attack Considerations
Resource Needs: Staffing and Apparatus
Critical Operational Tasks
Apparatus Placement
Hose Line Placement
Safety Considerations
Exposures
Contingency Issues: What can go wrong?
Assuming you are just arriving on scene and observe the backdraft conditions from the front seat; What would your operational IAP be and why?
Identify and discuss the types of mission critical size-up consideration that must be recognized and processed?
How does apparatus placement affect incident operations?
What first-due operational factors have you experienced that were contingent upon other tasks or considerations that were apparent to you or you implemented?
How does extreme fire behavior and fire dynamics affect your fire ground position?
How does this scenario and building size and type relate to similar structures and occupancies in your district or mutual aid/greater alarm response area?
Los Angeles Firefighters Battle Major Emergency at Townhouses Under Construction
Under-construction building fire forces dozens of evacuations

Operational Divisions with Exposures (Pre-Construction) Bing Maps
A townhouse complex under construction caught fire on November 10, 2011, in the Brentwood neighborhood of Los Angeles (CA). The six-unit, wood-framed complex was in its construction phase, where at least two of the units were fully involved in fire upon arrival of LAFD companies. Four of those six structures were severely damaged as a result of the construction stage and the degree of open wood frame construction resulting in rapid flame spread and extension to a nearby residential buildings.
According to published reports, the Los Angeles Fire Department was called at 3:37 a.m. to 12315 Gorham Avenue which resulted in a major emergency alarm classification decared and resulted in the dispatch and deployment of over 160 firefighters to the site. First arriving companies found a large townhome development with “heavy fire showing.”
Largely due to an aggressive fire attack by the LAFD, the footprint of this blaze was kept in-check and fully extinguished in one hour and 39 minutes. Fortunately, there were no injuries to any civilians or Firefighting personnel.
Additionally, five adjacent structures were evacuated for precaution. Two of those structures- one, a small apartment complex and the other, a single family dwelling, did sustain significant fire damage. As many as 10 families were displaced from those two occupancies.
Following further investigation, the LAFD stated it believed the fire was intentionally set.
Construction Site Operational Considerations (not inclusive)
Pre-Fire Plan Large Construction Projects
Understand the various Phases to a Construction Project and how they affect fire operations
Identify and train for nonconventional Strategic and Tactical operational actions
Ensure predetermined multiple alarm resources are identified and greater alarms are established
Train your Company and Command Officers to address Construction site fires
Maintain an appropriate risk profile balance with operational needs with personnel safety foremost
Clearly establish multiple Safety Offices and establish geographical resources within the incident management system for reconnaissance, communications, and oversight and focused safety monitoring
Know you water supply and system capabilities and limitations
Determine fire flow needs based upon construction phases, as these change over time as the building goes up. Match fire flow demands with resource availability (time of day gaps etc.)
Identify exposures (Physical structures and Civilians) and ensure they are calculated into the incident action plan at the right before there are identified needs or concerns
Companies shall maintain a conservative safety posture; this is not the time for overly aggressive firefighting, it is the time for smart firefighting that can be highly efficient
Always consider collapse zones: partial or complete. Stay out of them!
Respect the wind; it’s not going to help you
Consider current and projected weather conditions in your operational and tactical plans and assignments
Did I already say: Pre-fire Planning?
Be calculated in the placement of your apparatus, especially in larger scale incidents that are defined under greater geographical divisions
The fire usually consumes the available fuel load rapidly; going from a Huge fire, to one that is sometimes much more manageable; just watch and control your exposures and degree of fire extension. Don’t help to make the fire even bigger through ineffective and dysfunctional command and control
Anticipate, Project, Plan and Engage
Respect the Fire: it’s not going to play by the regular rules of combat fire suppression and engagement as in finished and enclosed structures and buildings.

There are numerous factors to be cognizant of in operations involving commercial buildings and occupancies; with special considerations and a diligent focus on a wide degree of facets on the fireground during combat fire engagement.
You need to start somewhere, thus the investment in these observations and insights for this event. Open your eyes on the fireground, there is so much to take in and respond to; if you know what to look for and can process what you’re seeing.
It is mission critical to comprehend and understand your department’s operational capabilities and the necessary deployment demands for fire suppression, fire flow and phased operations at commercial building fires.
Commercial Fire and Collapse
Respect these buildings for the occupancy risk they present and not the typical occupancy type that we develop our conventional strategies, incident action plans and tactical deployments.
It’s a lot more than that, with far greater consequences; that may be very unforgiving.
A recent video clip making its way around the cyber fireground clearly depicted a very close-call and resulting near miss event to four firefighters at a four alarm fire involving a commercial building that housed an established insulation manufacturer and installation contractor.
The video shows within a very compressed time frame, the progression of rapidly deteriorating interior conditions, the adverse affects on the building’s structural systems and the results from the loss of load transfers that lead to a catastrophic wall collapse narrowly missing the crew of firefighters who were operating a hand line in the vicinity of an exterior overhead door. Fortunately the injuries sustained to the firefighters were minor in nature; however the consequences and results from this collapse could have been far different and significantly more severe.
Following a series of repeated viewings of the video clip and with each successive viewing, it became readily apparent that there was a lot more to these images of the collapse and the cursory focus on the resulting near miss event. Closer examination of the video clip and the still frames brought to light some obvious conditions and indicators that easily become lost in the rapidity of the sequence of the collapse; which really has the true story to be told.
It’s the mechanism and sequence of the collapse, the dynamics of the building’s performance and the building indicators that provide a training opportunity in further examining key factors, presenting insights that could be a focus for operational and command personnel at future incidents with common parameters and gaining some mental models in recognition-primed decision making that contribute to the naturalistic decision-making process.
If you know what to be looking for, then when you see it, you may be able to anticipate, project and implement in rapid succession appropriate measures dictated by the incident.
Four Alarm Commercial Building Fire with Collapse: Fire Photo by Ben Goldberry
In an effort to promote additional insights and bring forward these fundamental observations and experienced-based presumptions extended from these and other news video images, still photographs, additional reporting research and examination, and a review of other published media resources; the following observations presented in this overview brief are being conveyed to increase firefighter, company and command level awareness of key collapse indicators such as those present at this commercial fire and to further the concept of adaptive fireground management principles and increase awareness of fundamental building performance indicators and principles to help you increase your intuitive observations skills and translate them into proactive operational actions on the fireground-before an adverse condition occurs.[ i.e., being five steps ahead of the fire conditions].
Although this briefing makes use of the images and conditions depicted in the video clip and encountered by the fire department evident in the images; the susequent commentary and insights provided are not meant to provide direct or indirect opinions, renderings, criticism or censure towards the conduct of operations or the management of the incident by the respective department and it’s firefighting, command and support personnel who operated at the actual fire and experienced this near miss event first-hand.
We are grateful that the events of this alarm precluded anything worst occurring given the potential seriousness of the prevailing incident conditions and commend the fire department and it’s firefighters that provide these exceptional services each and every day to the citizens they serve and to the community they protect, in mitigating this serious fire; safely and successfully.
This incident and the resulting near-miss captured by the videographer provides the Fire Service with an exceptional opportunity given today’s far reaching capabilities of eMedia, this web site and direct and indirect readers, links, tweets, likes, reposting’s, uploads, downloads and sharing an opportunity to share the consequences of an extreme close-call and learn from it in a positive and constructive manner, so that firefighters, company officers, commanders and support personnel can better predict with knowledge, insight and at times intuition a better understanding of buildings and the structures and occupancies we operate within on the fireground.
There are numerous inherent indicators present at every incident scene we operate at that. As is in this near miss event and building collapse; it’s sometimes the subtle things that need to gain the attention of operationg companies and personnel and the ability to rapidly process, recognize and react.
Remember this: Building Knowledge = Firefighter Safety.
As a generality; it’s important to note that given heavy fire involvement in a structure (got fire), adaptive fireground management considerations would promote conservative considerations to anticipate and expect collapse (degraded or compromise; limited or catastrophic).
In the case of fires in commercial occupancies and buildings with;
Large Square footage/Floor areas
Significant fire loads
Large open structural system spans lacking compartmentation,
Unprotected steel components and assemblies
No Sprinkler Systems
Omitted, compromised or degraded passive or active protective or suppression systems
Significant openings along the exterior building envelope
Significant opening on the roof enclosure
Deep seated fires or rapidly escalating and extending fires
It is mission critical to comprehend and understand your department’s operational capabilities and the necessary deployment demands for fire suppression, fire flow and phased operations.
Respect these buildings for the occupancy risk they present and not the typical occupancy type that we develop our strategies, incident action plans and tactical deployments. Its alot more than that, with far greater consequences that may be very unforgiving.
Aerial Plan of Building and Collapse Area A-B
The Building
The fire incident involved a single story commercial building occupying approximately 32, 200 square feet of area on a multiple building site with proximal exposures. Manufacturing, warehousing and offices comprised the building’s operational use. An aerial plan view shows the geographical building scene divisions and the location and relationship of the Alpha- Bravo Side collapse zones that affected operations and resulted in the close-call and firefighter near-miss. The proximity of exposures, physical layout and orientation can be further assessed.
A review of public documents and records, incident reports and various media resources provided the following insights;
Overview Details
Alpha Street Side View- Adapted from Google Streetmaps
The view of the alpha street side identifies the building front facade, its main office entrance (center between dual overhead doors on the left and right). Pronounced on the alpha side facade is the presence of four (4) equally spaced overhead (OH) doors that provide direct access into the building’s interior. The subsequent collapse area is depicted at the A-B corner with special attention drawn to relationship of the wall plane and OH door proximity.
The relationship and this wall surface ( area square footage) and the presence of the OH door opening to the wall/ roof interface area that subsequently became compromised and collapsed is critical in further understanding the mechanism of the collapse sequence and also the positive effect it had on the survivability of the firefighters who were within the collapse zone at the time of the wall failure.
Don’t Always Stress the Corners
It’s been a common practice and fundamental fireground consideration to define the corner of a typical building as having safety considerations and prominence in the context of ladder company operations, laddering and roof work and in the placement of personnel and positioning of fireground operations.
Corner Building Operational considerations have included, but limited to;
Provides a potentially safe(er) area of operational refuge
Provides a location to safely position ground ladders for roof access/egress
Provides a location that has a potential higher degree of assurance for maintaining structural integrity in the event of a collapse condition of an outer wall
Will not fail in a catastrophic or monolithic manner due to the postulated presence of structural members on the vicinity of either the wall enclosure and/or the roofing structural system and assemblies
The design and construction configuration and orientation of the ninety degree angle of the building’s outer wall envelope (at the corner) provides predicated inherent structural stability
The typical type of structural or envelope construction may have a resulting ninety degree building corner having a more robust resistance to collapse and compromise due to the various types of enclosure systems (methods and materials) and assemblies and needed stability per engineering principles
In this instance (as shown in the Alpha side street view), the presence of the large overhead door in close proximity to the corner wall intersection and transition ( A-B side), actually makes this position, fireground proximity and travel paths highly prone to early and complete collapse potential in the event of a loss of the wall-roof component or assembly integrity or in the load bearing/transfer capabilities of the wall-roof assembly.
The presence and identification of a corner configuration similar to this in a commercial structure should result in a higher degree of considerations and risk assessment when formulation and deploying operational assignments and in the placement of personnel for task assignments in this proximity.
This operational area should be considered as a candidate for designation as a collapse zone based upon projected or defined operational considerations, incident conditions and predictive building characteristics, systems, materials and fire dynamics and conditions.
Alpha-Bravo Corner of Subsequent Collapse Aerial View
The view from the Alpha-Bravo Corner shows the collapse zones at grade and the affected area size.
As noted in the preceding narrative, the presence of the overhead door opening along the perimeter wall enclosure and outer envelope creates a risk area that would require monitoring, periodic reconnaissance and assessment during subsequent operations to determine structural stability and potential adverse conditions.
The proximity of the opening in relationship to the corner wall, roof support and structural span of the opening results in a very delicate balance of forces, loads, reliance and dependence that must be maintained for structural integrity and equilibrium.
The entire perimeter of the alpha side could be considered for a restricted collapse zone just in terms of wall opening alone sans the degree of actual or projected interior fire impingement or fire involvement.
Take some time to view the video clip a few times over before proceeding to the next sequence of fame images.

Aerial Overhead view of the building perimeter walls along the four divisions ( A-D) with the A-B corner that subsequently experienced the wall-roof compromise and resulting collapse.
The A-B corner and the affected ground areas around the collapse zone. Considerations for a collapse zone area on the A-B corner would have resulted in a minimum distance of twenty five (25) feet from the building base for all operations within this area. The collapse zone on the Bravo side extends into the exposure building due to its close proximity.
Always consider the building envelope materials of construction and systems present on the building. The use of concrete masonry units (CMU) is common, as is the use of pre-cast concrete and cast-in place and tilt-up concrete construction panels.
Variations in collapse dynamics and mechanisms of collapse may result in sizable increases in collapse zone distances from the building base with consideration for monolithic or partial wall collapse as well as safety considerations for bounce and travel over long distances of modular assembly building pieces ( i.e. concrete blocks, brick venner or material chunks).
We have not discussed collapse considerations for other building envelope systems such as metal panelized systems since these have entirely different collapse considerations and profiling, not applicable to this incident and assessment insights. The same is true when considering operating and collapse considerations at commercial buildings with ordinary construction or heavy timber systems (Type or Class III and IV). These to have different rules of predictive building performance and collapse safety considerations.
Typical Interior
The interior of the building included unprotected steel components and assemblies consisting of steel columns, beams and open web steel joists. These common and conventional structural support systems provided large free clear spans, common for typical warehouse and commercial occupancies. The presence and operability of functional fire suppression sprinkler system coupled with passive and active protective devices and compartmentation can help support proactive and aggressive fire suppression efforts in those conditions that have appropriate risk determinations and balanced risk-gain benefits.
The presence of unprotected steel components ( Truss, column, structural beams etc. ) and assemblies requires an understanding of the effects of flame and heat impingement, rate of heat release and fire dynamics, potential for movement and displacement of structural components and effect on assemblies, systems and connections and the effect on structural stability, integrity and building load transfers and displacement that all can adversely affect building performance, integrity and collapse potential
Typical Structural System and Components
Interior View with Steel Columns, Open Web Steel bar Joists and Beams
Typical Open Web Steel Bar Joists w Metal Roof Deck
Large clear spans provided by the open web steel bar joists allowed for considerable free floor space typical of commercial warehouse occupancies.
Note the use of what appears to be combustible wood storage and staging areas that could have could potentially contribute towards increased fire intensity, extension and further contribute towards adverse affects on the unprotected structural steel components and assemblies.
Alpha Side Collapse Area Details: OH Door Pre-Collapse Insights
Pre-Collapse Operations on Alpha side with personnel in close proximty to the building perimeter
Pre-Collapse view of Operations on the Alpha side with personnel in close proximity, (within [a] collapse zone) to the building perimeter. It is evident that the degree of interior fire extension and involvement presumes a cautious deployment and placement of personnel in safe operational areas. When operating in such close proximity to the building wall and envelope, it becomes increasingly challenging for company officers and company personnel to monitor overall building performance indicators that may be prevalent or dominant from a view point further away from the building.
Fire extension, smoke conditions, component or assembly movement or displacement may be readily defined and identified from a vantage point away from the building, requiring additional independent operational assignments within the division if resources allow. Otherwise, officers are encouraged to get a big picture view and increase their span of vision of the building and progressing fire conditions and building performance
The pre-collapse frame image above identifies the building roof line in relationship to the ground operations, smoke conditions and also the directional flow of the elevated master stream [upper right corner]. The initial stage of the wall compromise and collapse can be seen in the Bravo wall pulling away. When watching the video, pay close attention first to the stream direction and flow and them at the location and movement of the wall, which is followed in rapid succession with the full wall collapse.
T
Close examination of the initial video frames shows the rapid displacement of the portion of the Bravo wall and outward collapse towards the B-Exposure (alleyway) Refer to the Aerial Plan for orientation. The A-B Collapse is progressing from the Bravo side to the Alpha side as loads are being transferred in rapid progression with further collapse expected.
The frame image above shows the bravo wall failing outward with the resulting loss in structural support of the roofing deck assembly.
Rapid fire migration and extension is evident after the wall section collapse with increased flames visible. In the video, one firefighter quickly recognizes the imminent collapse and reacts.
A significant section of wall area is present at the A-B side and progressing from the building corner to the left jamb of the overhead (OH) door. This area and the area directly above the OH door opening is calculated to weigh over 20,000 lbs.
The early identification and establishment of collapse zone(s) is mission critical especially at commercial buildings due to the considerations for rapidly changing operational conditions that may be a result of or influenced by the following;
lack of knowledge or understanding of the building’s construction, systems and characteristics
lack of adequate resources, skills and or capabilities for selected phase operations
fire loading, combustibles, flammables and other products
Last of or loss of compartmentation
fire and protective systems failures or inoperability
unapproved alterations, additions and renovations to the building, systems and occupancy
transitions for offensive to defensive operational phases, which at times may results in operating position postures too close to the building
failure to recognize situational factors that will drive appropriate operational phasing and task deployments
lack of building performance knowledge
not considering occupancy risk versus treating the building/fire relationship based upon occupancy type
not recognizing key collapse indicators and failing to implement timely actions [proactively versus reactionary]
being four steps behind the fire conditions evident instead of implementing adaptive fire ground management insights [five steps ahead of the evident fire]
use precise coordination when placing elevated masterstreams into operations with ground personnel operating within close quarters
understand the effects of master streams on the integrity of building features, assemblies and components
The image frame above shows personnel operating within an imminent collapse zone directing hand lines into the interior fire area. Further examination of the video frames clearly shows one firefighter quickly recognizing that a collapse is occurring and attempts to alert the other personnel to retreat. Simultaneously to the collapse progression, the crew immediately retreats away from the collapsing wall and falling building materials.
Within the span of four seconds, the wall compromise occurs and collapses on the ground at the A-B corner and immediate area on the alpha side. The slightly monolithic manner in which the wall plane first peels away and progressively collapsed is interesting for a CMU wall. Possibly due to the outward collapse of the Bravo wall, followed by the rapid succession of failure of the roof-wall connection interface resulted in an transitional downward force that pushed the alpha side wall outward allowing gravity to work its force
When operating in close proximity to a heavily involved forward interior condition [exterior position] it is important to maintain focused situational awareness and either directly maintain or delegate responsibilities for observations of fire and smoke progress and conditions while monitoring key functional building performance indicators and collapse pre-cursors.
Additionally, always re-evaluate the effectiveness of deployed and operational hose lines, streams and in water application to ensure they are adequate for the degree of fire suppression being undertaken and the corresponding fire flow requirements. Don’t just assume, determine with validity. [ Refer to Tactical Entertainment]
Obscured by the rapidly defining smoke which is a result of the developing and extending collapse, the frame image 04 below depicts the beginning of the compromise and collapse sequence commencing as a result of the Bravo wall compromise and collapse sequence at the B-A corner that will subsequently peel towards the Alpha side and continue up to the outermost jamb of the overhead door.
Pay particular attention to the first three to four seconds of the video clip and review the video clip over a few times; looking at the operating elevated master stream that is clearly visible and operating from the upper right part of the screen through the smoke plume; follow the direct orientation and stream flowing directly towards the bravo wall plane, and presumed penetrating into/through the roof deck or impacting through the metal roof deck and wall-roof assembly area at the upper roof edge.
Image 04
Frame image 04 depicts the rapidly deteriorating conditions that are evident as the collapse sequence continues and the overhead door jamb (left) buckling and adjacent wall failing by way of an outward curl or peel away commencing from the upper (left image) A-B corner at the roof line and then peeling and failing from upper left to right.
Image 05
The leading edge of the outward collapsing wall plane ( yellow dotted line) is failing with the greatest material concentration occurring at the A-B edge outward. Fortunately the presence and location of the overhead door opening lessened the amount and location of wall material ( concrete masonry units-CMU) and contributed to a void area being present and not fully impacting the firefighters who were operating within this collapse zone.
In other words, had this been a solid full wall collapse likelihood for significant firefighter injury would have resulted.
The affects of wall/roof compromise should be of focused consideration and monitoring when managing incidents of this size and magnitude in similar occupancies and building features. Flame and heat impingment can and will affect the structural integrity of lintels spans, beams and truss connects along roof lines and connections. Look for signs of impingment, degradation or compromise. watch for signs of probable inward/outward or curtain wall collapse.
Image 06
The remaining images, frames 06 and 07 depict the location of the firefighters to the wall collapse, the relationship to the wall and roof system and the degree of wall area that became compromised and collapsed.
Image 07
This brief video clip and these accompanying briefing insights provided a tremendous opportunity to examine in a non-critical manner an actual near miss collapse event and operational discernments that provide a focused training an awareness opportunity.
When given the time to analyze and assess, some things become so apparent and self-revealing that we might prematurely say why didn’t someone pick up that or those conditions while conducting operations at [an] incident. It is dependent on a wide variety of factors, conditions and parameters that are difficult at times to identify and harder yet to fully identify as common or contributing factors, errors or omissions.
It’s not always that easy; but contradictory – some time it really is (or should be) that easy.
Some things on the fireground may not be prone to being so readily identifiable or recognized.
It all depends what you’re looking for and whether you have the necessary insights, knowledge and skill sets. Incident priorities, demands, situational focus, awareness or disconnect all may have a part in how and incident is managed and mitigated.
It goes back directly on knowing what to look for and when; at what type of building with which type of occupancy and under what stage or stages of fire development and combat operations or engagement you might be in. It complex, it takes time and experience and learning’s.
There are numerous factors to be cognizant of in operations involving commercial buildings and occupancies; with special considerations and a diligent focus on a wide degree of facets on the fireground during combat fire engagement.
You need to start somewhere, thus the investment in these observations and insights for this event. Open your eyes on the fireground, there is so much to take in and respond to; if you know what to look for and can process what you’re seeing.
It is mission critical to comprehend and understand your department’s operational capabilities and the necessary deployment demands for fire suppression, fire flow and phased operations. Respect these buildings for the occupancy risk they present and not the typical occupancy type that we develop our conventional strategies, incident action plans and tactical deployments. It’s a lot more than that, with far greater consequences; that may be very unforgiving.

Fire Modeling Software
These fire simulation programs were developed or sponsored by the Fire Research Division at the NIST. The list of programs is divided into two broad categories below: currently-supported software and archival (unsupported) software. In order to get further information or to obtain one of the programs, click on the appropriate name.
Current Software
These models are being actively developed and supported by the laboratory. Details of the software, including download, development, and support information are included on the individual web pages for each model.
FDS (Fire Dynamics Simulator) is a computational fluid dynamics (CFD) model of fire-driven fluid flow. The software solves numerically a form of the Navier-Stokes equations appropriate for low-speed, thermally-driven flow, with an emphasis on smoke and heat transport from fires.
These models are included largely for reference or historical interest and span several decades of development of computational tools in fire research at NIST. As such, they are largely unsupported due to the age of the software.
ALOFT-FTTM (A Large Outdoor Fire plume Trajectory model – Flat Terrain) is a computer based model to predict the downwind distribution of smoke particulate and combustion products from large outdoor fires. It solves the fundamental fluid dynamic equations for the smoke plume and its surroundings with flat terrain. The program contains a graphical user interface for input and output and a user modifiable database of fuel and smoke emission parameters. The output can be displayed as downwind, crosswind and vertical smoke concentration contours. Information on using the program is available with on-line help commands in the program.
ASCOS (Analysis of Smoke Control Systems) is a program for steady air flow analysis of smoke control systems. This program can analyze any smoke control system that produces pressure differences with the intent of limiting smoke movement in building fire situations. The program is also capable of modeling the stack effect created in taller buildings during extreme temperature conditions. The program input consists of the outside and building temperatures, a description of the building flow network and the flows produced by the ventilation or smoke control system. The output consists of the steady state pressures and flows throughout the building. Another newer program, CONTAM, may be more appropriate to some applications than ASCOS.
ASET-B (Available Safe Egress Time – BASIC) is a program for calculating the temperature and position of the hot smoke layer in a single room with closed doors and windows. ASET-B is a compact easy to run program which solves the same equations as ASET. The required program inputs are a heat loss fraction, the height of the fire, the room ceiling height, the room floor area, the maximum time for the simulation, and the rate of heat release of the fire. The program outputs are the temperature and thickness of the hot smoke layer as a function of time.
ASMET (Atria Smoke Management Engineering Tools) consists of a set of equations and a zone fire model for analysis of smoke management systems for large spaces such as atria, shopping malls, arcades, sports arenas, exhibition halls and airplane hangers. ASMET is written in C++ language. For program documentation and a description of the input data, the user should refer to NISTIR 5516, Klote, J. H., Method of Predicting Smoke Movement in Atria with Application to Smoke Management, NIST.
BREAK1 (Berkeley Algorithm for Breaking Window Glass in a Compartment Fire) is a program which calculates the temperature history of a glass window exposed to user described fire conditions. The calculations are stopped when the glass breaks. The inputs required are the glass thermal conductivity, thermal diffusivity, absorption length, breaking stress, Young’s modulus, thermal coefficient of linear expansion, thickness, emissivity, shading thickness, half-width of window, the ambient temperature, numerical parameters and the time histories of flame radiation from the fire, hot layer temperature and emissivity, and heat transfer coefficients. The outputs are temperature history of the glass normal to the glass surface, and the window breakage time.
CCFM (Consolidated Compartment Fire Model version VENTS) is a two-layer zone-type compartment fire model computer code. It simulates conditions due to user-specified fires in a multi-room, multi-level facility. The required inputs are a description of room geometry and vent characteristics (up to 9 rooms, 20 vents), initial state of the inside and outside environment, and fire energy release rates as a functions of time (up to 20 fires). If simulation of concentrations of products of combustion is desired, then product release rates must also be specified (up to three products). Vents can be simple openings between adjacent spaces (natural vents) or fan/duct forced ventilation systems between arbitrary pairs of spaces (forced vents). For forced vents, flow rates and direction can be user-specified or included in the simulation by accounting for user-specified fan and duct characteristics. Wind and stack effects can be taken into account. The program outputs for each room are pressure at the floor, layer interface height, upper/lower layer temperature and (optionally) product concentrations.
DETACT-QS and DETACT-T2
DETACT-QS (DETector ACTuation – Quasi Steady) is a program for calculating the actuation time of thermal devices below unconfined ceilings. It can be used to predict the actuation time of fixed temperature heat detectors and sprinkler heads subject to a user specified fire. DETACT-QS assumes that the thermal device is located in a relatively large area, that is only the fire ceiling flow heats the device and there is no heating from the accumulated hot gases in the room. The required program inputs are the height of the ceiling above the fuel, the distance of the thermal device from the axis of the fire, the actuation temperature of the thermal device, the response time index (RTI) for the device, and the rate of heat release of the fire. The program outputs are the ceiling gas temperature and the device temperature both as a function of time and the time required for device actuation. DETACT-T2 (DETector ACTuation – Time squared) is a program for calculating the actuation time of thermal devices below unconfined ceilings. It can be used to predict the actuation time of fixed temperature and rate of rise heat detectors, and sprinkler heads subject to a user specified fire which grows as the square of time. CT-T2 assumes that the thermal device is located in a relatively large area, that is only the fire ceiling flow heats the device and there is no heating from the accumulated hot gases in the room. The required program inputs are the ambient temperature, the response time index (RTI) for the device, the activation and rate of rise temperatures of the device, height of the ceiling above the fuel, the device spacing and the fire growth rate. The program outputs are the time to device activation and the heat release rate at activation.
ELVAC (Elevator Evacuation) is an interactive computer program that estimates the time required to evacuate people from a building with the use of elevators and stairs. It is cautioned that elevators generally are not intended as a means of fire evacuation, and they should not be used during fires. However, it is possible to design elevator systems that for fire emergencies, and ELVAC can be used to evaluate the potential performance of such systems. ELVAC calculates the evacuation time for one group of elevators. If a building has more than one group of elevators, ELVAC can be run on each group separately. Input consists of floor to floor heights, number of people on floors, number of elevators in the group, elevator speed, elevator acceleration, elevator capacity, elevator door type and width, and various inefficiency factors. The output is a table of elevator travel time, round trip time, people moved, and number of round trips for each floor plus the total evacuation time.
FIRDEMND simulates the suppression of post flashover charring and non-charring solid-fuel fires in compartments using water sprays from portable hose-nozzle equipment used by the fire departments. The output of the Fire Demand Model (FDM) shows the extinguishing effects of water spray at various flow rates and droplet sizes. The calculations are based on a heat and mass balance accounting for gas and surface cooling, steam-induced smothering, water-spray induced air entrainment, direct extinguishment of the fire by water and the energy transport via inflow and outflow of heat and products of combustion.
FIRST (FIRe Simulation Technique) is the direct descendant of the HARVARD V program developed by Howard Emmons and Henri Mitler. The fire may be entered either as a user-specified time-dependent mass loss rate or in terms of fundamental properties of the fuel. In the latter case, the program will predict the fire growth rate by considering the changing oxygen concentration and smoke layer conditions in the room of fire origin. It can also predict the heating and possible ignition of up to three targets. The original fire and targets may also be user specified fires. The required program inputs are the geometrical data describing the rooms and openings, and the thermophysical properties of the ceiling, walls, burning fuel, and targets. The generation rate of soot must be specified, and the generation rates of other species may be specified as a yield of the pyrolysis rate. Among the program outputs are the temperature and thickness of, and species concentrations in, the hot upper layer and also in the cooler, lower layer in each compartment. Also given are wall surface temperatures, heat transfer rates and mass flow rates. MASBANK is used to create and maintain a data base of materials and their fire properties for use by the FIRST program. MASBANK can accommodate 20 properties for up to 50 materials. The program has the capability to add, delete, change, alphabetize and view the material properties in the data bank. Material properties from MASBANK may be transferred directly into the FIRST program.
Jet is a model for the prediction of detector activation and gas temperature in the presence of a smoke layer.
FPETool (Software and Documentation) is a set of engineering equations useful in estimating potential fire hazard and the response of the space and fire protection systems to the developing hazard. Version 3.2 incorporates an estimate of smoke conditions developing within a room receiving steady-state smoke leakage from an adjacent space. Estimates of human viability resulting from exposure to developing conditions within the room are calculated based upon the smoke temperature and toxicity.
LAVENT is a program developed to simulate the environment and the response of sprinkler links in compartment fires with draft curtains and fusible link operated ceiling vents. The model, used to calculate the heating of the fusible links, includes the effects of the ceiling jet and the upper layer of hot gases beneath the ceiling. The required program inputs are the geometrical data describing the compartment, the thermophysical properties of the ceiling, the fire elevation, the time dependent energy release rate of the fire, the fire diameter or energy release rate per area of the fire, the ceiling vent area, the fusible link response-time-index (RTI) and fuse temperature, the fusible link positions along the ceiling, the link assignment to each ceiling vent, and the ambient temperature. A maximum of five ceiling vents and ten fusible links are permitted in the compartment. The program outputs are the temperature, mass and height of the hot upper layer, the temperature of each link, the ceiling jet temperature and velocity at each link, the radial temperature distribution along the interior surface of the ceiling, the radial distribution of the heat flux to the interior and exterior surfaces of the ceiling, the fuse time of each link, and the vent area that has been opened.GRAPH is a graphics program which runs in conjunction with LAVENT. The results for LAVENT are sent to the data file, GRAPH.OUT, after each prescribed time step. GRAPH then allows the user to choose two sets of variables to be plotted on the screen and has the additional capability of hardcopy output.

Accessed from FDNY - Remembering the "23rd Street Fire" October 17, 1966, Facebook Page
On October 17th 1966, Manhattan Box 598 was struck at 21:36 hours for the report of a building fire at 7 East 22nd Street, an art dealer in a four story brownstone. On arrival, the heat and smoke was so intense companies could not make entry through the art dealer, and so attempted to make entry by way of the abutted building 6 East 23rd Street, The Wonder Drug store.
Crews were dealing with a very intense and spreading fire. With companies operating above the fire, little indication of a catastrophic collapse was present. Suddenly, a 16×35 foot section of the floor collapsed at around 22:39 hours causing ten firefighters to fall into the burning cellar. Two other firefighters on the first floor were killed in a burst of heat.
Firefighters evacuated immediately, except for some whom were trapped on the roof with direct flame impingement. Hand lines from the ground and a truck company ladder was able to rescue the group in time. Rescue operation ensued long into the morning. Several evacuations were ordered, and further collapses occurred. Aside from 9/11, this was the largest single line of duty death event in the FDNY’s history.
Stored in the basement of the art dealer were large quantities of highly flammable lacquer, paint, and finished wood frames. The first floor was supported by 3″ x 14″ wood beams. 3/4″ wood planking atop these beams was covered with five inches of concrete finished with terrazzo and insulated against all heat to the firefighters operating above. As part of a recent project, a common cellar under the two buildings was renovated, removing a load-bearing dividing wall that had supported the floor above. The cellar of the art dealer extended under the drug store illegally from this renovation.
The fire burned unknowingly in the Wonder Drug basement for over an hour when it finally collapsed. It took 14 hours to locate all downed firefighters in the rubble; the cause of the fire is unknown.

Building Alteration
(1) The fire building, 7 East 22 St, had a two story extension which abutted the rear of 6 East 23 St.
(2) The Cellar of 7 East 22 St extended under the first floor of 6 East 23 St for approximately 35 feet.
(3) The floor construction of 6 East 23 St was 3″ x 14″ wood beams topped by 3/4″ wood planking. On top of this, five inches of concrete with a terrazzo finish was added.
The firefighters in exposure 3, (6 East 23 St), killed in the collapse did not know they were operating directly over the cellar fire in 7 East 22 St. The five inch concrete terrazzo floor acted as an insulator.
It concealed the severe fire and heat below. The 3 inch x 14 inch floor beams spaced 16 inches on center were reduced in size and strength by the fire.
The first sign of weakness was the sudden collapse of a 15 x 35 foot section, which plunged the ten firefighters to their deaths. Two other firefighters were killed on the first floor by a ball of flame.

Three Franklin (OH) firefighters were caught in what has been determined to be a smoke explosion at a structure fire involving a restaurant occupancy in what appears to be a building of Type III construction that published reports indicated was built in 1892.
Franklin (OH) FD Lt. Kyle Lovelace and firefighters Quincy Pearson and Brad Brown were caught in a smoke explosion while conducting interior fire suppression operations at which time conditions deteriorated and a smoke explosion occurred. Simultaneous with the recognition that something was not good; the crew immediately began to retreat when they were caught in the explosion. All of them luckily made it out unscathed.
According to published reports, “They reverted back to their training and did what they needed to do to get out,” according to Fire Chief Jonathan Westendorf . “We have a flashover simulator and we spend a good amount time talking about it each year.”
Reports have indicated Lt. Lovelace stated that when they arrived on the scene, he noticed smoke coming from left side of the building above the second floor and thought that it may be an attic fire.
They attempted to gain entry through the front door, but before they opened it they noticed a crack in the window and decided to gain entry through the rear. Lt. Lovelace, FF Pearson and FF Brown entered an alley covered by an awning connecting to freestanding structures. Westendorf later said his guys were fortunate to be in that location because they were isolated from the brunt of the blast.
The crew advanced about 25 feet when FF Pearson, who was on the nozzle, saw wisps of smoke and began to feel extreme heat.
Lt. Lovelace used a thermal imaging camera to locate where the heat was coming from, but right before he could tell Person, he started yelling at him to get out. They made it about 20 feet when the thick black smoke started banking down on them. As Lovelace exited under the awning, conditions quickly worsened and the smoke explosion occurred.

Eric Clark for the Chicago Tribune / August 25, 2011
Four Chicago firefighters have been injured while battling a fire in the city’s West Englewood neighborhood Thursday night according to news media outlets. The fire was located within a 1-1/2 story wood frame residential occupancy in which fire suppression operations were underway.
Fire companies operating within the attic area with attack lines operating, experienced rapidly degrading conditions in which published reports indicated the “room lit up” suggesting a possible flashover condition. It was reported that vertical ventilation had been completed on the gable style roof and that coordinated company operations were well established both on the number one floor, within the attic and on exterior support operations.
Research indicates the house was built in 1905 and has 990 square feet of space. Constructed of balloon wood framing, the 1-1/2 story single family residential occupancy is typical of this vintage style housing.
Chicago’s fire commissioner credited the quick response of rescuers after firefighters were hit by a flash of flames while working in the attic of a home in theWest Englewood neighborhood. “It’s a matter of seconds before we would have had a different outcome,” Fire Commissioner Robert Hoff said at Loyola University Hospital, where two of the four firefighters injured in the blaze remained hospitalized.
As reported by the Chicago Tribune (HERE) The fire started in the basement of a 1 1/2-story home in the 7000 block of South Justine Street and spread through the walls to the attic, Hoff said. As firefighters ventilated the roof and worked to extinguish the blaze, they were not aware of fire burning inside the walls behind them, Hoff said. Flames suddenly “lit up on them,” he said. “This is an example of how extremely dangerous and unpredictable this job is,” said Tom Ryan, president of Chicago Firefighters Union Local 2. “There is no such thing as a routine fire.”
The two firefighters still hospitalized are a 52-year-old captain who suffered burns to his ears and back of the neck; and a 31-year-old firefighter with burns to his left hand and forehead. They suffered the burns when their masks were knocked loose as they tried to escape, Hoff said. Both are from Engine 54 and are stable, Hoff said.
A third firefighter who was taken to Loyola was released early this morning, and a fourth taken to Mount Sinai Hospital Thursday night. Fire Officials credited the Fire Department’s five-person rapid intervention team — which is routinely called to fires — for responding so quickly.

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)
