Worcester Cold Storage Tragedy

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

NIOSH LODD Report Released on Fire and Collapse Which Killed Two Chicago Firefighters
F2010-38  Two Career Fire Fighters Die and 19 Injured in Roof Collapse during Rubbish Fire at an Abandoned Commercial Structure – Illinois

NIOSH Executive Summary
On December 22, 2010, a 47-year-old male (Victim # 1) and a 34-year old male (Victim # 2), both career fire fighters, died when the roof collapsed during suppression operations at a rubbish fire in an abandoned and unsecured commercial structure. The bowstring truss roof collapsed at the rear of the 84-year old structure approximately 16 minutes after the initial companies arrived on-scene and within minutes after the Incident Commander reported that the fire was under control. The structure, the former site of a commercial laundry, had been abandoned for over 5 years and city officials had previously cited the building owners for the deteriorated condition of the structure and ordered the owner to either repair or demolish the structure. The victims were members of the first alarm assignment and were working inside the structure. A total of 19 other fire fighters were hurt during the collapse.

Contributing Factors

 

  • Lack of a vacant / hazardous building marking program within the city
  • Vacant / hazardous building information not part of automatic dispatch system
  • Dilapidated condition of the structure
  • Dispatch occurred during shift change resulting in fragmented crews
  • Weather conditions including snow accumulation on roof and frozen water hydrants
  • Not all fire fighters equipped with radios.

Key Recommendations

  • Identify and mark buildings that present hazards to fire fighters and the public
  • Use risk management principles at all structure fires and especially abandoned or vacant unsecured structures
  • Train fire fighters to communicate interior conditions to the Incident Commander as soon as possible and to provide regular updates
  • Provide battalion chiefs with a staff assistant or chief's aide to help manage information and communication
  • Provide all fire fighters with radios and train them on their proper use
  • Develop, train on, and enforce the use of standard operating procedures that specifically address operations in abandoned and vacant structures

NIOSH Recommendations

  • Recommendation #1: Fire departments and city building departments should work together to identify and mark buildings that present hazards to fire fighters and the public.
  • Recommendation #2: Fire departments should use risk management principles at all structure fires and especially abandoned or vacant unsecured structures.
  • Recommendation # 3: Fire departments should train fire fighters to communicate interior conditions to the Incident Commander as soon as possible and to provide regular updates.
  • Recommendation # 4: Fire departments should consider providing battalion chiefs with a staff assistant or chief's aide to help manage information and communication.
  • Recommendation # 5: Fire departments should provide all fire fighters with radios and train them on their proper use.
  • Recommendation # 6: Fire departments should develop, train on and enforce the use of standard operating procedures that specifically address operations in abandoned and vacant structures.
  • Recommendation # 7: Fire departments should develop, implement and enforce a detailed Mayday Doctrine to ensure that fire fighters can effectively declare a Mayday.
  • Recommendation # 8: Fire departments should ensure that the Incident Commander maintains close accountability for all personnel operating on the fireground
  • Recommendation # 9: Fire departments should ensure that fire fighters are trained in fireground survival procedures.
  • Recommendation #10: Fire departments should ensure that all fire fighters are trained in and understand the hazards associated with bowstring truss construction.

The tragic events in the City of Chicago on Wednesday December 22, 2010, when Chicago Firefighter Edward J. Stringer – Engine Co.63 and Firefighter/EMT Corey D. Ankum, Truck Co.34 were killed in the line of duty while operating at a structure fire in an abandoned one-story brick building in the 1700 block of East 75th Street on the City’s South side, exemplifies the demands, challenges and sacrifice that come with responsibilities, duty and sworn obligation  that distinguishes the honorable profession of being a firefighter.     

The fire was first reported at about 06:48 hours during the night and day tour shift change, with companies arriving at 06:52 hours reporting moderate fire in the  buildings northeast corner. The single story commercial structure was vacant, however it was readily known that squatters were known to seek shelter in the abandoned structure especially give the harsh weather being experienced in the city. The fire was quickly contained at approximately 07:00 hours according to published reports, and radio communications, with coordinated suppression, search and rescue and ventilation operations being conduction by companied both within the interior and on the roof. 

Other Operational Safety Insights and Considerations from CommandSafety.com and Buildingsonfire.com

  • During all operations involving actual or suspected Bowstring Truss Roofing Support Systems Command and Company Officers should be sensitive to risk assessment indicators related to both fire induced conditions as well as environmental and age induced factors.
  • Pre-plan your buildings look at the construction, components, features and condition of the building; there is a tremendous amount of information out there. Understand and comprehend what to look for, what it is that you’re looking at and more importantly make sure the information is retrievable for on-scene application and that the information is utilized when formulating IAP and in the dynamic risk assessment process
  • During Dynamic Risk Assessment, special attention should be focused on Predicated Building Performance common to identified building systems, features and structural systems that are based upon Occupancy Performance and NOT Occupancy Type.
  • The Federal Emergency Management Agency’s (FEMA) United States Fire Administration (USFA) issued a special report examining the characteristics of fires in vacant residential buildings. The report, Vacant Residential Building Fires, was developed by USFA’s National Fire Data Center and provides useful insights and recommendations. Link HERE
  • When developing incident action plans and operational assignments at incidents involving possible Vacant, Unoccupied or Abandoned structures, command and company officers shall implement a formulative risk -benefit assessment consistent with departmental procedures, policies and expectations.
  • Be knowledgable of operational factors and considerations related to operations at Vacant, Unoccupied or Abandoned structures; HERE and HERE
  • Read the Newest NIOSH Alert: Preventing Deaths and Injuries of Fire Fighters at Structure Fires, HERE
  • Start considering building; age, deterioration, environmental impacts and influences in your IAP and tactical considerations, we at times forget to consider these performance indicators effectively during initial or sustained operations.
  • Learn more about Building Construction, Occupancy Profiling, Reading a Building, Occupancy Risk versus Occupancy Type and always consider Tactical Patience.
  • Increase your knowledge on Structural Collapse indicators especially for buildings of masonry construction in both Type III and Type IV construction.
  • There is a Predictability of Performance in all Buildings and Occupancies with Heavy Timber or Built-up Bowstring Truss Structural Systems; Know what they are.
  • Understand what to look for in Heavy Timber or Built-up Bowstring Truss Structural System integrity related to; Age and Deterioration, Gravity, Cross Grain Shrinkage, Wood Defects that are self-evident in chords and web members, Upper Chord Buckling, Lower Chord splitting or failure points, web splitting or pull-outs, multiple roofing systems or membranes, multiple void spaces, compromised bearing walls or pilasters, compromised or degraded bearing points or truss ends.
  • Learn to identify masonry wall features and what they mean towards tactical operations
  • In smaller single story occupancies; any loss of structural integrity of a single truss component would likely cause the compromise or collapse of adjacent truss components and connective decking planks due to the interdependence and connectivity of the roofing support (trusses), purlins, rafters and roofing planks and outer membrane system. 
  • Typically the failure of one bowstring truss span will compromise or cause the collapse of each adjacent truss to either side of the original affected truss causing the failure of a sizeable roof area.
  • Companies operating on such affected roof area areas are subject to high risk and vulnerability should the roof area fail. Refer to the incident conditions and structural collapse from the Waldbaum’s Collapse, FDNY August 2, 1978. Go to the incident overview at Commandsafety.com HERE.
  • In smaller square foot commercial occupancies that have shallow depth bowstring truss components and both limited spans (less than 100 linear feet clear span) and number of trusses (six or less) the likelihood of a catastrophic roof collapse should be considered highly predicable in all incident action plans and during incident status monitoring.
  • The loss of load bearing and load transfer capabilities at these wall connections can contribute towards failure and collapse conditions. The end connections points (end cap or end shoe) of a bowstring truss are critical towards maintain truss performance and structural integrity.
  • The loss of truss axial orientation, resultant excessive deflection, loss of integrity of chord/ web geometry and connection points can lead to failure mechanisms and a cascading effect due to transferring of loads and possible overstressing and directly lead to subsequent failures.
  • It should be noted that fire service personnel should have a high degree of respect for the danger and susceptible risk imposed by compromised or failing bearing and non-load bearing walls.
  • Collapse zones must be established and access controlled based upon physical incident scene layout, access and proximal exposure structures.
  • All fire service personnel should have awareness level training and an understanding of recognizing collapse indicators for buildings of masonry construction and tactical safety considerations
  • Company and Command Officers must have a higher level of knowledge and training to be able to recognize subtle or obvious construction, conditions or indicators that will affect IAP, strategic, tactical or task assignments and be able to act upon those indicators with immediacy and urgency as conditions and risk dictate.
  • The Collapse Zone should be at a minimum be equal to the full height of the exterior masonry wall face and also take into consideration additional distance due building material momentum, bounce and toss due to individual bricks, steel lintels and other components and materials acting as projectiles and traveling distances greater than the defined “collapse zone”.

Hackensack (NJ) Ford Fire July 1, 1988

As we approach the July 4th holiday period, two significant LODD incidents previously occurred during this time frame that hold a number of lessons learned related to command management, operations, building construction principles and building performance, fire behavior and the ever present dangers of the job.

Take the opportunity to learn more about these events, and expand your insights and knowledge base.

Take a moment to reflect upon the supreme sacrifice made by these heroic firefighters and the messages that lay within the pages of the incident case studies, reports and summaries.

There’s a lot of practical safety and operational information on these events along with a tremendous volume of information in the various text books on strategy and tactics, incident command and building construction.

Learn from the past so we don’t repeat it. Remember- NO MORE HISTORY REPEATING EVENTS!

The Hackensack Ford Fire & Collapse occurred nearly ten years AFTER another tragic LODD event involving a bowstring truss roof collapse; the August 2nd, 1978 FDNY Waldbaum’s Fire, Brooklyn, New York that took the lives of six FDNY firefighters.

Twenty-Three Year Anniversary Hackensack Ford Fire and Truss roof collapse, Hackensack Fire Department. July 1st, 1988

Pause to remember our brothers who made the ultimate sacrifice twenty-three years ago, on July 1st, 1988 and the lessons learned from this event.

On July 1, 1988 Hackensack’s Captain RICHARD L. WILLIAMS, Lieutenant RICHARD REINHAGEN, Firefighter WILLIAM KREJSA, firefighter LEONARD RADUMSKI, and Firefighter STEPHEN ENNIS lost their lives at Hackensack Ford when a bowstring arch truss collapsed entrapping them in the area below. The five firefighters were in the structure, a bowstring truss building, when the roof suddenly collapsed a 60-foot square section of the building’s wood bowstring truss roof collapsed, and an intense fire immediately engulfed the area. Williams, Kresja and Radumski were killed instantly, and four other firefighters escaped. Reinhagen and Ennis survived the initial collapse and found refuge in a tool room where they spent the next 13 minutes calling for help.. . despite heroic rescue attempts, succumbed to carbon monoxide poisoning. Approximately 90 minutes after the collapse, firefighters located the bodies of their fallen comrades.

Three (3) building factors contributed to the collapse of this bowstring trussed roof:

• Alterations that consisted of a heavy ceiling of cementitious material on wire lathe;
• Auto parts storage in the attic; and
• The Fire burned for a significant length of time and was well advanced prior to detection.
• This roof collapsed 35 Minutes after the initial units arrived.

Remember:
• CAPT. RICHARD L. WILLIAMS, Engine Co. No. 304
• LIEUT. RICHARD REINHAGEN, Engine Co. No. 302
• F/F WILLIAM KREJSA, Engine Co. No. 301
• F/F LEONARD RADUMSKI, Engine Co. No. 302
• F/F STEPHEN ENNIS, Rescue Co. No. 308

NFPA SUMMARY
Hackensack, New Jersey Fire Fighter Fatalities July 1, 1988

Five fire fighters from the Hackensack, New Jersey Fire Department were killed while they were engaged in interior fire suppression efforts at an automobile dealership when portions of the building’s wood bowstring truss roof suddenly collapsed. The incident occurred on Friday, July 1, 1988, at approximately 3:00 p.m., when the fire department began to receive the first of a series of telephone calls reporting “flames and smoke” coming from the roof of the Hackensack Ford Dealership.

Two engines, a ladder company, and a battalion chief responded to the first alarm assignment. The first arriving fire fighters observed a “heavy smoke condition” at the roof area of the building. Engine company crews investigated the source of the smoke inside the building while the truck company crew assessed conditions on the roof. For the next 20 minutes, the focus of the suppression effort was concentrated on these initial tactics.

During this time, however, little headway appeared to have been made by the initial suppression efforts, and the magnitude of the fire continued to grow. The overall fire ground tactics were shifted to a more “defensive” posture (exterior operation) and the battalion chief gave the order to “back your lines out.” However, before suppression crews could exit form the interior, a sudden partial collapse of the truss roof occurred, trapping six fire fighters. An intense fire immediately engulfed the area of the collapse. One trapped fire fighter was able to escape through an opening in the debris. The other five died as a result of the collapse. This incident and several others before and since, provide important lessons to the fire service regarding the fire ground hazards of wood truss roof assemblies.

This NFPA Summary may be reproduced in whole or in part for fire safety educational purposes as long as the meaning of the summary is not altered, credit is given to NFPA and the copyright of the NFPA is protected.

Following is an excerpt from the New York Times article:
Demers contended that Chief Williams, primarily because of the volume of fire on the rooftop, should have ordered nine firefighters out of the garage within 7 minutes of his arrival. The order to pull out was given at 3:34 p.m., about 30 minutes after his arrival, the report said.

  • “This radio message was not acknowledged by any companies,” the report said.

The roof collapsed at 3:36 p.m. Three firefighters were hit by burning debris and killed, four escaped, and two, Lieut. Richard R. Reinhagen and Stephen Ennis, took refuge in the tool room.

  • At 3:39 p.m., Lieutenant Reinhagen began to radio his location and appeal for help, the report said.

In one of the major communications flaws cited by Mr. Demers at the fire scene, all departmental communications were transmitted on a single channel, or frequency. Consequently, Lieutenant Reinhagen’s appeals for help were intermingled with orders for deploying men and hoses and instructions to arriving companies.

  • “You have to hurry, we’re running out of air,” Lieutenant Reinhagen said at 3:42 p.m.

Headquarters then radioed to Chief Williams: “Expedite on that, they’re running out of air.” The transcript did not show any response from Chief Williams.Over the next 6 minutes, through 3:48 p.m., Lieutenant Reinhagen made 10 more calls. None was answered. For three of the minutes, bells indicating depletion of his air tanks’ supply were ringing repeatedly. At one point, a civilian who overheard the ringing on a radio scanner called fire headquarters to tell officials of the noise.

At 3:49 p.m., the Lieutenant radioed: “Chief, this is Lieutenant Reinhagen. I’m still stuck back in the right rear of the building in the closet. We are out of air in a closet. We’re out of air.”
“What’s your location?” Chief Williams said. The response was inaudible and the Chief began ordering water from a truck.

At 3:50 p.m., the Lieutenant got the Chief directly and repeated that they were “stuck in a closet” and “out of air.”

  • “Stuck in a closet?” Chief Williams asked.

Twelve seconds later, the Chief Williams asked: “Where you at?”

  • “Right there in the closet,” came the response.
  • Fourteen seconds later, Lieutenant Reinhagen radioed again: “Help. The right rear. Out of air. Anybody out there? Stuck in the closet, right rear. No air. Help.”

The Lieutenant was asked if he was on the first or second floor. “First floor, underneath the collapsed ceiling,” the Lieutenant said at 3:52 p.m. It was his last transmission. Firemen eventually punched a hole through an exterior wall about 10 feet from the tool room, but saw only a mass of flame, Mr. Demers said. The burning timbers were leaning against the tool room, he said, but neither fireman was burned.

Learn from the past so we don’t repeat it. Remember- NO MORE HISTORY REPEATING EVENTS!

Some Open Questions;

  • What impact did the Hackensack Ford Fire & Collapse have upon you in your career?
  • Were you aware of this event and its lessons learned prior to this posting?
  • What do you feel you need to learn related to Building Construction, Fire Behavior or Strategy and Tactics related to various occupancies and construction types?
  • What is you knowledge base on Truss Construction related to Timber Bow String or Engineered Structural Systems?

Three Firefighters and Three Sisters Killed in Gloucester City, New Jersey Building Collapse during Fire Attack, Rescue Operation, July 4th, 2002

Gloucester City (NJ) Collapse 2002

On July 4th, 2002 at 0136 hrs.,The Gloucester City Fire Department was dispatched to 200 North Broadway for a reported house fire. Responding units were advised that occupants may be trapped. First arriving units were on location in less than three minutes.

They found heavy fire on all exposures of a three-story multi-family dwelling and initiated a search for entrapped occupants. (Various reports from bystanders were at times conflicting regarding the number and location of victims). While providing an aggressive interior attack and rescue operation, an occupant was rescued from the dwelling. Due to the severity of their injuries they were unable to give direction regarding the whereabouts of any other occupants.

While all hands were operating by continuing an aggressive interior attack and rescue, a partial collapse of the structure occurred. An emergency evacuation signal was sounded and while that was commencing a further and much more substantial collapse occurred trapping eight firefighters inside the burning debris.

Additional specialized collapse rescue resources were requested, firefighter accountability was initiated and rescue efforts were intensified. Five of the eight trapped firefighters were rescued. Three of the eight gave the ultimate sacrifice in service to their fellow man. Unfortunately these three children did not survive. A total of nine victims were transported to area hospitals, one civilian and eight firefighters.

Remember:
• James Sylvester
Fire Chief, Mount Ephraim Fire Department
Sylvester, 31, a 17 year veteran, was survived by his wife, who was pregnant with the couple’s first child
• John West
Deputy Chief, Mount Ephraim Fire Department
West, 40, a 23-year veteran, was survived by his wife and three children
• Thomas G. Stewart III
Paid Firefighter, Gloucester City Fire Department
Stewart, 30, a 13 year veteran, was survived by his fiancée and their son. Stewart publicly proposed to his girlfriend, hours before the fire while they watched the city’s fireworks from high atop a fire truck ladder at Gloucester City High School.

NIOSH REPORT: Structural Collapse at Residential Fire Claims Lives of Two Volunteer Fire Chiefs and One Career Fire Fighter – New Jersey, HERE

Philadelphia Inquirer Posting, HERE

Everyone Goes Home Newsletter Article by Chris Collier, HERE

New Jersey Division of Fire Safety LODD Report, HERE

SUMMARY
On July 4, 2002, a 30-year-old male volunteer fire chief, a 40-year-old male volunteer deputy fire chief, and a 30-year-old male career fire fighter died when a residential structure collapsed, trapping them, along with four fire fighters and an officer who survived. At 0136 hours, a combination fire department and a mutual-aid volunteer fire department were dispatched to a structure fire. Local law enforcement radioed Central Dispatch reporting a fully involved structure with three children trapped on the second floor. The first officer on the scene assumed incident command and reported to Central Dispatch that the incident site was a three-story structure with fire showing and that people could be seen at the windows. Note: The female resident (survivor) was the person seen in the window.

The three children that were reported as being trapped did not survive and were later found in the debris. Additional units were requested, including a mutual-aid ladder company from a career department. Crews were on the scene searching for occupants and fighting the fire for approximately 27 minutes when the building collapsed.

NIOSH investigators concluded that, to minimize the risk of similar incidents, fire departments should;
• Ensure that the department’s structural fire fighting standard operating guidelines (SOGs) are followed and refresher training is provided
• Ensure that the Incident Commander (IC) formulates and establishes a strategic plan for offensive and defensive operations
• Ensure that the incident commander (IC) continuously evaluates the risk versus gain during operations at an incident
• Ensure that a separate Incident Safety Officer, independent from the Incident Commander, is appointed
• Ensure that fire fighters conducting interior operations (e.g., search and rescue, initial attack, etc.) provide progress reports to the IC
• Ensure that accountability for all personnel at the fire scene is maintained
• Ensure that a Rapid Intervention Team (RIT) is established and in position
• Ensure that the officer in charge of an incident recognize factors (e.g., structural defects, large body of fire in an old structure, etc.) when analyzing potential building collapse
• Ensure, when feasible, that fire fighters should respond together, in one emergency vehicle, as a crew
Additionally, municipalities should consider
• Establishing and maintaining regional mutual-aid radio channels to coordinate and communicate activities involving units from multiple jurisdictions

In order to minimize the risk of similar incidents, the New Jersey Division of Fire Safety identified key issues that must be addressed and remedies that should be implemented within all departments.

1. FACTOR: There appears to be a disconnect between career and volunteer personnel in the Gloucester City Fire Department (GCFD). Many personnel expressed the concern that the GCFD operated as separate fire departments rather than as one.

REMEDY: It is essential that all firefighters put individual differences aside in order to work together successfully as a team to achieve their common goal of saving lives and property.

2. FACTOR: The GCFD, faces a common dilemma associated with combination fire departments: staffing levels may be unpredictable depending on how many volunteers are available to respond to any one incident. This unpredictability can result in insufficient staff to perform required tasks until additional staff arrives.

REMEDY: Elected or appointed municipal officials need to make a commitment to the adequate staffing of the fire department and staffing levels must allow for compliance with the two-in / two-out provisions of the Public Employees Occupational Safety and Health (PEOSH) Standard 29CFR1910.134. The New Jersey Division of Fire Safety can provide assistance to the municipalities and provide examples of how this can be accomplished

3. FACTOR: Due to the limited number of firefighting personnel who arrived at this incident, all initial efforts were focused on the rescue of occupants. This postponed fire suppression operations until additional resources arrived. Because rescue and fire suppression operations were performed sequentially rather than simultaneously, the fire may have spread more quickly resulting in the early failure of the structure.

REMEDY: Sufficient personnel are critical to ensure that all necessary operations can be performed at the appropriate time. Furthermore, a continual size-up assessment must be maintained so that the Incident Commander (IC) can be kept aware of the conditions as the incident progresses. This continual size-up will allow the IC to modify the strategy and / or tactics as deemed necessary.

4. FACTOR: Although the GCFD was equipped with a thermal imaging camera (TIC), firefighters failed to utilize it for the initial search for victims. The TIC was also not used properly to analyze the scope of the incident and determine what tactics to employ.

REMEDY: Fire departments that possess TIC units should use them regularly during routine operations such as training, scene size up, search and rescue and structural fire fighting.

5. FACTOR: From the onset of operations, the Incident Management System (IMS) was not properly expanded as the incident progressed. Given the scale of this incident, the span of control quickly became too large for the IC to effectively manage and additional functions were not delegated to subordinates. Critical tasks such as safety and accountability were not effectively implemented.

REMEDY: N.J.A.C. 5:75 mandates that all fire departments utilize an IMS. It is a modular system, which allows the IC to apply only those elements that are necessary at a particular incident, and allows elements to be activated or deactivated as incidents escalate or decline. Fire departments are required to adopt written plans, or Standard Operating Guidelines (SOG’s) based on the IMS, to address different types of incidents. The NJ Division of Fire Safety distributed suggested SOGs upon adoption of this regulation and they continue to be available to all fire departments.

6. FACTOR: The GCFD did not assign a dedicated safety officer (SO) to observe operations and terminate potentially unsafe actions.

REMEDY: IMS regulations under N.J.A.C. 5:75 mandate the use of safety officers (SO’s) at all incidents. An SO is required to observe operations on the fire scene, identify next steps and order the correction of safety hazards to personnel. Given the scope of this incident, the IC should have assigned at least one SO.

7. FACTOR: The GCFD did not designate accountability officers to monitor each area of entry into the structure. Nor was a Personal Accountability Report (PAR) or roll sheet utilized to track personnel and monitor their functions. Therefore, the concept of accountability of personnel location, function, and time failed.

REMEDY: Although not enforceable at the time of this incident, the regulations for the NJ Personal Accountability System (NJPAS) under N.J.A.C 5:75 now require that fire departments utilize an accountability system. This system includes the designation of accountability officers and the use of PAR’s / roll calls, all within the framework of the IMS that is required to be utilized at all incidents. The NJ Division of Fire Safety is in the process of finalizing suggested SOGs and will distribute them to all fire departments when complete.

8. FACTOR: Although firefighters Sylvester and Stewart were equipped with Personal Alert Safety System (PASS) devices, they did not activate them prior to entering the structure. It should be further noted that their PASS devices were not automated; they had to be manually activated by the user. Firefighter West was not equipped with a PASS device.

REMEDY: PASS devices must be provided, used, and maintained in accordance with PEOSH regulations under N.J.A.C. 12:100-10 et seq. Although many departments still rely on PASS devices that must be activated manually, – devices that are acceptable by PEOSH regulations – they are not ideal because the firefighter must remember to activate the PASS device. For this reason, fire departments should strongly consider upgrading their SCBA to those employing automatic activating PASS devices.

9. FACTOR: The GCFD did not specifically designate the required personnel for the rescue of distressed firefighters through the establishment of Rapid Intervention Teams (RIT) or Firefighter Assist and Search Teams (FAST). Consequently, when the building collapsed, there was not a properly equipped team in place for immediate rescue operations.

REMEDY: IMS regulations under N.J.A.C. 5:75 require that fire departments utilize RIT or FAST to rescue distressed firefighters when operating in a hazardous atmosphere. The IC should request a RIT or FAST as soon as possible after dispatch to allow the team to arrive quickly.

10. FACTOR: Not all fire departments operating on the fire ground were communicating on the same radio frequency, which resulted in communication failures. Although, the Camden Fire Department (CFD) did have the capability to communicate on the GCFD “Fire 5” frequency they chose not to.

REMEDY: IMS regulations under N.J.A.C. 5:75 require that a communication system allow for inter-agency communication during mutual aid responses by providing a direct communication link between companies. Fire departments should work with other departments that are used routinely for mutual aid to ensure radio interoperability.

11. FACTOR: An emergency evacuation signal was sounded upon reports of a firefighter missing inside the structure before the impending collapse, however, the signal was never sounded at any other time prior to the collapse, nor was it sounded immediately after the collapse.

REMEDY: In the event an emergency evacuation becomes necessary and an emergency signal is required, N.J.A.C. 5:75 requires that fire departments utilize an emergency evacuation signal that is easily recognizable and distinguishable from all other fireground noises. The signal must be utilized when conditions on the fireground indicate an imminent and extreme risk to firefighters. At this time NJ DFS is finalizing a proposal that would establish a statewide emergency evacuation signal.

12. FACTOR: During this incident, fireground conditions were not properly analyzed, which led to the failure to recognize an impending building collapse.

REMEDY: Firefighters and officers need to learn the warning signs and causes of building collapses. Often following a collapse, as was the case with this incident, personnel on the scene report that the structure collapsed “without warning”. However, this is usually not the case; the reality is that the IC and firefighters simply failed to identify the indicators that were present prior to the collapse.

13. FACTOR: After removal of all victims, the remaining structure was demolished and the incident scene was cleared of all debris within 48 hours of law enforcement concluding their origin and cause investigation. This prevented a thorough assessment of the remaining structure in order to identify the cause and contributing factors of the collapse.

REMEDY: A protocol should be adopted to ensure that fire scenes are secured in a manner that not only allows for public safety, but also prevents immediate demolition. This will provide agencies with an opportunity to conduct any investigations that may be necessary.

14. FACTOR It was difficult to gauge the amount of training for all GCFD personnel due to insufficient record keeping. Although it was determined that the GCFD firefighters and officers met the minimum regulatory training requirements, many members did not possess a great deal of supplemental training with regard to structural firefighting. Additionally, the volunteer firefighters and officers often did not attend the scheduled departmental drills and rarely trained with the career personnel despite having frequent opportunities to participate.

REMEDY: Standards such as NFPA 1500 recommend that fire departments establish a regular training and education program that is commensurate with the duties and functions that firefighters are expected to perform. Additionally, proper record keeping is essential to certify that all personnel have received both required and supplemental training or education.

15. FACTOR: Qualifications of volunteer officers were difficult to judge and there were serious concerns voiced by the career members of the department regarding the suitability of some of the volunteer officers. This resulted in a lack of confidence by several career personnel in the volunteer officers and reluctance to take direction from them.

REMEDY: In addition to the NJ DFS requirement that all fire service supervisors obtain incident management certification; municipal officials need to establish uniform minimum qualifications for fire officers in order to ensure the effective provision of fire suppression services to the public. The NJ DFS recently adopted voluntary fire officer standards and will be developing a training curriculum to meet those standards.

16. FACTOR: It was not possible to determine if a smoke detector inspection was conducted in the building after a change in occupancy in October of 2001 as required by the NJ Uniform Fire Code. The city’s housing department, who has the responsibility for these inspections, was unable to provide documentation of such an inspection to either the Division of Fire Safety or to the Camden County Prosecutor’s Office. It was not clear whether smoke detectors were activated during this fire incident.

REMEDY: It is recommended that the responsibility for smoke detector inspections be transferred to the fire department to ensure complete and documented inspections.

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

3 comments

Fire Service Tradition and The Brotherhood

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

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

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

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

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

History Repeating Events-Integrate into your Training

 

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

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

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

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

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

What are we Learning? What are we Applying?

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

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

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

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

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

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

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

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

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

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

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

 

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

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

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

Predicting Fire Behavior and Building Stability

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

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

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

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

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

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

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

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

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

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

Think about the following;

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

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

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

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

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

The New Fire Ground

NIST Wind Driven Fire Study

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

NIST Fire Fighting Tactics Under Wind Driven Conditions: Laboratory Experiments

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

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

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

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

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

Fire Behavior 101; Taking it to the Streets

  

  

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

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

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

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

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

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

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

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

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

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

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

Room Flashover from Sofa Fire

 

The tactical considerations addressed include:

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

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

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

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

New Rules of Engagement

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

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

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

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

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

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

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

 

Original IAFC 2001 ROE

 

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

 

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

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

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

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

These included the;

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

 Three Section members also participated in the IAFF project.

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

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

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

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

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

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

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

The project team was lead by Chief Gary Morris,

 The Need for Rules of Engagement

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

 

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

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

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

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

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

 

Operational Excellence and the ROE

 

The NEW Rules of Engagement

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

  • 16 Fire Fighter Life Safety Initiatives

  • Rule of Engagement

  • Fire Fighter Near-Miss Learning‘s

  • Procedures, Policies and Guidelines

  • Pre-Fire Planning

  • Building Construction

  • Structural Systems

  • Occupancy Risk Profiling

  • Fire Dynamics & Fire Behavior

  • Reading Smoke

  • Survivability Profiling

  • Risk Management

  • Crew Resource Management

  • Situational Awareness

  • Disorientation Awareness

  • Structural Collapse & Compromise

  • Mayday & Rapid Intervention

  • Fire Ground Survival

  • Air Resource Management

  • Tactical Patience

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

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

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

Understand your Response District

 

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Regardless of your agency and respond district size, complexity of simplicity, Pre-Incident Plans are a necessary part of modern firefighting and all-hazards operations.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

 Just Look Over your Shoulder….

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

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

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

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

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

Better Look Over your Shoulder

 

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

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

  

Remember its Occupancy RISK not Occupancy TYPE

 

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

 

STOP THE ENTERTAINMENT

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

These behaviors include;

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

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

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

  

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

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

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

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

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

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

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

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

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

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

  

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

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

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

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

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

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

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

  

 

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

Chicago: Anatomy of a Building and its Collapse PDF Training Aid

The recent post titled: Chicago: Anatomy of a Building and its Collapse has been receiving a considerable amount of attention as the post makes its way throughout the fire service eMedia sites, links, likes, shares and commentary circles, with over 6,000 views in the past 24 hours on various sites.

It furthers the premise that I have advocated my entire career and that is the fire service continues to recognize the need for increased knowledge, training, insights and skill sets related to building construction and its diametric relationship to firefighter, command risk management and operational safety.  

And that we need to learn from each and every incident response,operation and run….Let’s continue to gain learnings and insights from not only this event,  but from the vast resources of published LODD investigations, after-action reports, case studies, near-miss events and close-calls; for each has a lesson that we can use on our next call.

In order to provide support for continuing training and insight opportunities, I’ve developed a PDF download of the Chicago: Anatomy of a Building and its Collapse article in its entirety.

FF Edward J. Stringer FF/EMT Corey D. Ankum

The tragic events in the City of Chicago on Wednesday December 22, 2010, when Chicago Firefighter Edward J. Stringer – Engine Co.63 and Firefighter/EMT Corey D. Ankum, Truck Co.34 were killed in the line of duty while operating at a structure fire in an abandoned one-story brick building in the 1700 block of East 75th Street on the City’s South side, exemplifies the demands, challenges and sacrifice that come with responsibilities, duty and sworn obligation  that distinguishes the honorable profession of being a firefighter.     

The fire was first reported at about 06:48 hours during the night and day tour shift change, with companies arriving at 06:52 hours reporting moderate fire in the  buildings northeast corner. The single story commercial structure was vacant, however it was readily known that squatters were known to seek shelter in the abandoned structure especially give the harsh weather being experienced in the city. The fire was quickly contained at approximately 07:00 hours according to published reports, and radio communications, with coordinated suppression, search and rescue and ventilation operations being conduction by companied both within the interior and on the roof. 

Timeline of Events
It was during this phase of operations that a mayday was rapidly communicated at 07:07 hours after a portion of the roof and rear masonry wall unexpectedly collapsed sending personnel operating on the roof riding down with the collapse and trapping four firefighters within the confines of the interior voids. RIT was immediately deployed at the scene for the trapped personnel with reports of numerous firefighters injured by the collapsing wall into the alley way on the Charlie and Delta sides.

Non-Bearing Sidewall lateral "push-out" collapse resulting from the inward failure of the roof system into the interior

The incident escalated quickly to a 3-11 alarm with subsequent manpower and resources dispatched to provide immediate collapse search, rescue, extrication, medical treatment and incident scene management and support. The resulting structural collapse killed firefighters Stringer and Ankum and injured seventeen other firefighters.

Previous Incident coverage HERE, HERE, HERE and HERE. 

Operations in the Charlie Side Alleyway

In this incident the Rules of Structural Fire Engagement were clear and resonated with the commitment and resolve that define the American Fire Service. Companies committed to tactical deployment operations consistent with departmental operating procedures and policy that required interior fire suppression, in conjunction with a coordinated interior search and rescue task assigned  and supported by roof ventilation. Although the one-story brick building was clearly abandoned and vacant; it was not known if it was unoccupied, thus the tactical search and rescue assignment. According to Chicago Fire Commissioner Robert Hoff, firefighters entered the burning structure because of reports there may have been squatters inside the old laundry and cleaning facility. 

By all indications this alarm was a conventional fireground operation being conducted in a fashion consistent with the operating procedures and protocols of the Chicago Fire Department (CFD), executed in a formulative manner that was predicated upon similar past building performance and operations successes.  Various news reports and audio recordings of fireground communications identified that first arriving companies recognized the building and occupancy type and were aware that the building had a characteristic bowstring truss roof system in the rear (Charlie side) of the occupancy. CFD procedures dictate identification of the degree of fire involvement or impingement within the truss loft area (concealed or open area located within the open void space of the truss chords between the underdeck of the roof and the bottom chord of the truss) to determine risk and impact on further tactical operational deployment and task assignments. 

The CFD is adeptly aware of the historical characteristics, hazards and safety concerns associated with firefighting operations in buildings of bowstring truss construction. The Chicagoland area has an abundance of vintage building types with an array of occupancies that have characteristic small and large span structural bowstring truss systems. 

CFD Firefighters know bowstring truss roofs only too well because of the risk of collapse. Twelve years ago, two firefighters died when the bowstring truss roof collapsed on them while fighting a fire in a tire and auto repair shop in Beverly. The roof in the Beverly fire was already ablaze. In the case of 1744 East 75th Street, companies did not identify any fire extension or impingement within the truss loft area during initial phases of deployment and initiated tactical operation assignments accordingly based upon the fire location and strategic incident action plan. 

FF Ankum and FF Stringer were killed by the crushing weight of the collapsed roof. With a structural support system comprised of wood timbers configured in a bowstring style truss system, this structural support system and construction style was common in the late 1920s when the building at 75th and Stony Island in South Shore was built. The truss is arched like a bowstring and provides a clear span within a room or large compartment floor area without intermediate vertical support columns. The structural truss component is typically anchored along the exterior walls where the roof load is transferred to the vertical walls and transmitted down to the foundation. 

The building and occupancy at 1744 East 75th Street however did have a risk profile not related to its occupancy type and one that was not readily known to operating company or command officers during the initial stages of fireground operations; that this building was in state of disrepair and had received numerous citations and notices of action. The unstable nature of the building, the apparent poor condition of the roof and inherent deficiencies in the structural support system and construction created an operational risk profile that could not be identified readily through conventional size-up by arriving and deploying command or company officers. 

It was reported that the city had previously cited the building owner for numerous building code violations; including failing to maintain the roof- which, according to the violation, had holes and was rotted and leaking. The violation also indicated the roof trusses were vented and rotted. It is not known if pre-fire plan information was readily available to responding companies or if recent first-due company level inspections or walk-thru had been initiated or completed.

In an effort to provide timely learning’s from this incident and in advance of the more thorough and detailed subsequent investigative reports and information that will be forthcoming in the months ahead, I’d like to provide some insights and basic information to increase firefighter, company and command officer awareness and knowledge related to the operational concerns for similar buildings with bowstring truss structural roof systems and share some observations related to presumptions  deduced from incident scene photos.  The representative insights derived from this incident are in no way meant to analyze or offer criticism towards any element of the operations conducted at 1744 East 75th Street; but are provided to increase your knowledge of building features to support operations at similar structures and occupancies so as to reduce the likelihood of other history repeating events (HRE) in your jurisdiction or response district.

These insights are based upon an analysis of incident scene photographs, internet based images and maps from Google, Bing along with video and audio media clips. Interpretations and assumptions made (especially related to dimensions, size and configurations) are representative to provide content to scale and similarities with other typical construction features in an effort to advance firefighter knowledge.

Anatomy of the Building and Collapse 

The structure at 1744 East 75th Street appears to have been part of a larger series of collective occupancies and structures that previously spanned the entire city block, sharing construction features and commonalities consistent with construction methodologies and practices in the 1920’s through the 1940’s. An aerial view of the 1700 block of East 75th Street clearly shows the series of one-story brick buildings sharing both common party walls and possibly independent bearing walls between separate occupancies, with their distinctive roof profiles and varying square footage of floor area. 

The Alpha [A] side is East 75th Street with a common parallel alleyway located on the Charlie [C] side. The collapse area appears to have been approximately a 60 feet (depth) x 50 feet (width) for an area of ~ 3000 square feet. The outward failure of the Delta [D] side load bearing also occured as the roof failed inward into the building. Published reports indicated the roof system present in the immediate collapse zone was comprised of bowstring truss components. This is evident in a series of fireground photos that clearly depict the remnants of a shallow depth built-up chord bowstring truss comprised of timber wood components. 

Built-up Bowstring Timber Truss Component

Bearing End of a built-up Bowstring Chord Truss

It appears the bowstring wood truss components rested on top a series of four (4) brick wall pilasters and pocketed within the east and west brick bearing walls. The north non-bearing brick wall appears to be a three wythe solid brick wall, with the bearing walls running east-west. The non-bearing brick wall running parallel to the alley way was the main portion of wall that collapsed outward as a result of the inward collapse of the truss roof support system, wood rafters and plank roof deck. The inward momentum created by the downward forces of the failing roof area, pushed outward the entire north wall face, which based upon the modular charactoristics of the brick and mortar, most likely caused the wall to collapse in sizeable sections (outward collapse as well as disintegrate into smaller projectiles with a classical curtain failure. Photos suggest the wall failure resulted in a collapse zone that spanned the entire narrow alley way from wall to wall (estimated at 18 +/- feet) leaving no room to escape the lateral failing wall collapse without running in an east and west direction only. 

The single story size of this common Type (Class) III Ordinary Construction building which is estimated at 18 feet in height appears to have had a parapet wall raising above the roof line, consistent with design features found in buildings of this vintage. 

The single story height coupled with the square foot floor/roof area, any loss of structural integrity of a single truss component would likely cause the compromise or collapse of adjacent truss components and connective decking planks due to the interdependence and connectivity of the roofing support (trusses), purlins, rafters and roofing planks and outer membrane system. 

  • Typically the failure of one bowstring truss span will compromise or cause the collapse of each adjacent truss to either side of the original affected truss causing the failure of a sizeable roof area.
  • Companies operating on such affected roof area areas are subject to high risk and vulnerability should the roof area fail. Refer to the incident conditions and structural collapse from the Waldbaum’s Collapse, FDNY August 2, 1978. Go to the incident overview at Commandsafety.com HERE.
  • In smaller square foot commercial occupancies that have shallow depth bowstring truss components and both limited spans (less than 100 linear feet clear span) and number of trusses (six or less) the likelihood of a catastrophic roof collapse should be considered highly predicable in all incident action plans and during incident status monitoring.
  • The loss of load bearing and load transfer capabilities at these wall connections can contribute towards failure and collapse conditions. The end connections points (end cap or end shoe) of a bowstring truss are critical towards maintain truss performance and structural integrity.
  • The loss of truss axial orientation, resultant excessive deflection, loss of integrity of chord/ web geometry and connection points can lead to failure mechanisms and a cascading effect due to transferring of loads and possible overstressing and directly lead to subsequent failures.

Photo examination further identifies the presence of concrete masonry units (CMU) evident in a number of incident scene images that suggests renovations and alterations at some point in the building’s recent history that may have had an impact on the building’s integrity or performance profile ( postulated, actual or forecasted). 

  • It should be noted that fire service personnel should have a high degree of respect for the danger and susceptible risk imposed by compromised or failing bearing and non-load bearing walls.
  • Collapse zones must be established and access controlled based upon physical incident scene layout, access and proximal exposure structures.
  • All fire service personnel should have awareness level training and an understanding of recognizing collapse indicators for buildings of masonry construction and tactical safety considerations
  • Company and Command Officers must have a higher level of knowledge and training to be able to recognize subtle or obvious construction, conditions or indicators that will affect IAP, strategic, tactical or task assignments and be able to act upon those indicators with immediacy and urgency as conditions and risk dictate.
  • The Collapse Zone should be at a minimum be equal to the full height of the exterior masonry wall face and also take into consideration additional distance due building material momentum, bounce and toss due to individual bricks, steel lintels and other components and materials acting as projectiles and traveling distances greater than the defined “collapse zone”.

Collapse Rescue Void Search Operations

  • The sheer weight and mass present in a brick wall presents significant probability of debilitating injuries and death if caught in the collapse zone by falling wall sections or brick projectiles.
  • A standard common brick may weight 4.5 – 6 lbs. each. An 8 inch wide brick wall may weigh upwards of 83 pounds per square foot (PSF).
  • For illustration purposes; A 50 foot long wall x 18 feet in height constructed with a solid 8 inch wide brick non-load bearing wall (assuming 15% openings for doors/windows) would have an estimated dead load weight of 63,500 lbs. (31.75 ton)
  • Fire Service personnel must be aware of the three common exterior masonry wall mechanisms of collapse  that include; outward monolithic wall collapse,  inward/outward wall collapse and curtain fall collapse. Building height, width (wyth) of the wall, bearing or non-bearing wall types, weather conditions, fire impingement or exposure and age, reinforcement, deterioration/integrity of mortar joints etc., all have influencing effects on the actual manner in which an exterior masonry wall will collapse.
  • In smaller single story commerical structures of Ordinary Type III construction, the 90-degree monolithic and/or curtain-fall wall collapse can be expected.
  • The probability of void spaces being present due to a catastrophic collapse of a bowstring truss roof system are predicated upon the presence of interior space features such as shelving, equipment, products/materials and any small height area partitions or physical barriers (that may even extend upwards to the understructure of the truss chord) and the manner in which the structural bowstring truss component and integrated roofing system fail or compromise from the outer wall bearing points. (pancake, lean-to)
  • The collapse of the roofing deck system resulting from a compromise or collapse of the bowstring truss system may cause under some circumstances a longitudinal failure or cracking of the upper masonry wall either along the line of the roof/parapet interface or in an area immediately beneath this point.
  • The resulting impact due to dynamic load transfers may cause the upper masonry wall and/or parapet to collapse inward while simultaneously causing the lower masonry wall section to collapse in an outward manner into the exterior collapse zone.
  • The manner in which the exertion of force applied to the outer masonry wall during the mechanism of the collapsing of the roofing system will determine the extent of force, failure and degree of brick material that will be deposited at the base of the wall and beyond within the collapse zone.

Built-up bowstring trusses such as the ones that appear to have been present at 1744 East 75th Street came in varies sizes related to the dimension of the structural wood components utilized (heavy timber or built-up), the depth of truss related to its span and its load bearing design/capacity (and the subsequent truss loft void created by the truss top and bottom chord as well as the manner in which the truss  web members were held together, the connection methods utilized and the manner in which the truss component was designed to be seated in its load bearing position (pocketed or surface load bearing). 

The following photographs provides a representative example of a heavy timber truss showing the steel U-shaped end shoe (bolted to the bottom chord) seated on the bearing plate of the pilaster. This is a common connection point and is a critical area for maintaining the structural integrity and stability of the roof system. These load bearing points are susceptible to age related deterioration of the bearing surface, shoe connection/chord connection, loss or degradation of the bearing wall conditions, decay or deterioration of the end connections that adversely affect the structural stability of the top truss cord to transfer the thrust loads imposed upon this connection into the bottom chord.

Note: the crack in the bottom wood chord running from the steel shoe and bolt connections, indicating an area of concern 

A bowing or outward thrust of brickwork on a visible exterior bearing wall is a clear indication that deterioration has occurred and that the structural stability of the wall roof system is in question as well as the stability to conduct safe tactical interior or roof operations by fire service personnel. 

  • Other age related conditions affecting bowstring truss stability include creep deformation, stressed, loosened or damaged connection points due to imposed loads over many decades, the effects on longer deflection under load, the effects or wood shrinkage and drying affecting the geometry and thus strength and stability of the truss, along with a higher potential for structural failure and collapse.

These conditions can all be exasperated by fire, heat impingement or contact as well as long term imposing dead loads of the roofing system(s) and more importantly live loads such as rain or snow accumulation (as well as concentrated live loads) or the placement of fire personnel to conduct tactical roof assignments. Published research and test results  have shown that in many instances heritage vintage truss systems such as the bowstring truss (circa 1880-1950) were designed in a manner that did not take into account conservative bottom cord tensile strength design. Most trusses from this time frame were not designed under the same criteria implemented in today’s building codes and specifications and thus are prone to compromise and failure under a variety of both fire and non-fire induced incident scenarios.

Another key observation point during operational assessment and size-up includes the observation of any excessive truss chord sag along the span, rot, deterioration, cracked or split chords, splices, web members of visible end connections. The identification of  such conditions during any phases of operations such be promptly evaluated as a pronounced high risk to personnel safety and further operational integrity. In other words; it’s time to immediately reconsider risk, strategic and tactical operational objectives and the likelihood for isolated structural compromise or catastrophic structural collapse.

Other Insights and Considerations 

  • During all operations involving actual or suspected Bowstring Truss Roofing Support Systems Command and Company Officers should be sensitive to risk assessment indicators related to both fire induced conditions as well as environmental and age induced factors.
  • Pre-plan your buildings look at the construction, components, features and condition of the building; there is a tremendous amount of information out there. Understand and comprehend what to look for, what it is that you’re looking at and more importantly make sure the information is retrievable for on-scene application and that the information is utilized when formulating IAP and in the dynamic risk assessment process
  • During Dynamic Risk Assessment, special attention should be focused on Predicated Building Performance common to identified building systems, features and structural systems that are based upon Occupancy Performance and NOT Occupancy Type.
  • The Federal Emergency Management Agency’s (FEMA) United States Fire Administration (USFA) issued a special report examining the characteristics of fires in vacant residential buildings. The report, Vacant Residential Building Fires, was developed by USFA’s National Fire Data Center and provides useful insights and recommendations. Link HERE
  • When developing incident action plans and operational assignments at incidents involving possible Vacant, Unoccupied or Abandoned structures, command and company officers shall implement a formulative risk -benefit assessment consistent with departmental procedures, policies and expectations.
  • Be knowledgable of operational factors and considerations related to operations at Vacant, Unoccupied or Abandoned structures; HERE and HERE
  • Read the Newest NIOSH Alert: Preventing Deaths and Injuries of Fire Fighters at Structure Fires, HERE
  • Start considering building; age, deterioration, environmental impacts and influences in your IAP and tactical considerations, we at times forget to consider these performance indicators effectively during initial or sustained operations.
  • Learn more about Building Construction, Occupancy Profiling, Reading a Building, Occupancy Risk versus Occupancy Type and always consider Tactical Patience.
  • Increase your knowledge on Structural Collapse indicators especially for buildings of masonry construction in both Type III and Type IV construction.
  • There is a Predictability of Performance in all Buildings and Occupancies with Heavy Timber or Built-up Bowstring Truss Structural Systems; Know what they are.
  • Understand what to look for in Heavy Timber or Built-up Bowstring Truss Structural System integrity related to; Age and Deterioration, Gravity, Cross Grain Shrinkage, Wood Defects that are self-evident in chords and web members, Upper Chord Buckling, Lower Chord splitting or failure points, web splitting or pull-outs, multiple roofing systems or membranes, multiple void spaces, compromised bearing walls or pilasters, compromised or degraded bearing points or truss ends.
  • Learn to identify masonry wall features and what they mean towards tactical operations

These are some immediate considerations for increasing operational integrity while maintaining firefighter safety and and does not reflect the full extent of safety or operational considerations that must be imposed and implemented at operations involving buildings of Type III or IV construction or those with bowstring truss components; but it is a stepping stone and for many, the first exposure to this type of information.

From emerging published reports, Two Chicago firefighters died after a wall collapsed during a 3-11 alarm fire at an abandoned South Side commercial building this morning, authorities said. Fourteen other firefighters were injured, including two who were trapped with the ones who died.    

Police squad cars escorted two ambulances north on Lake Shore Drive to Northwestern as ramps were closed to clear it of traffic, according to fire communications. One of the firefighters taken there has died, sources said. The condition of the other one was not known.    

A third trapped firefighter was taken to Christ Medical Center in Oak Lawn, where he died.  Late this morning, dozens of firefighters stood at attention, removing their caps and saluting, as the body of their fallen colleague was taken from the hospital and put in an ambulance.  A police escort led the ambulance to the medical examiner’s office    

The fourth firefighter buried in the rubble, and as many as 12 other firefighters with undisclosed injuries, were also taken to hospitals. Fire officials and sources said 10 were stable and six were taken to hospitals in serious to critical condition, including the two who later diedThe firefighters’ deaths came on the 100th anniversary of a huge fire at the Union Stockyards that claimed the life of 21 Chicago firefighters, the single greatest loss in U.S. history of professional big-city firefighters until Sept. 11, 2001.    

A dozen or fewer firefighters were in the building when the roof above them collapsed, said Fire Department spokesman Larry Langford. Firefighters searched through rubble for more than an hour as four trapped firefighters were pulled out and rushed to hospitals.    

“They worked hard, got them out fast,” said Fire Commissioner Robert Hoff at the scene.    

He said the search was continued, with dozens of firefighters digging through rubble, because of the possibility that homeless people may have been in the building seeking shelter from the cold. Neighbors reported that squatters have been staying in the building, but no others were found in the rubble.    

The fire broke out about 6:54 a.m. in the abandoned one-story brick building in the 1700 block of East 75th Street.    

The fire was raised to two and then three alarms to save the trapped firefighters. A “mayday” was called. Firefighters also reported having problems with frozen hydrants.

Informational Update- The two Chicago Firefighters have been identified;

  

  • FF Edward Stringer:    

  • FF Corey Ankum:     

  • According to published reports; Initial incident reports are that FF Stringer and FF Ankum had been on or near the roof of the building in the 1700 block of East 75th Street this morning with other Firefighters when it collapsed. The building had a bow string truss in the rear and a flat roof in front. 34-year-old Cory Ankum from Engine 72, had been on the department only sixteen months.  Corey had previously served as a Chicago Police officer before joining the city’s fire department.  His wife is Mayor Richard Daley’s personal secretary.  He is a father of three children under 12 years old, including a  one-year old child.    

  • FF Edward Stringer, a 12-year veteran of the CFD and is reported to have several grown children and lives alone.  Published sources are indicating, he was working as a “relief Lieutenant”, covering for another Lieutenant for an unknown reason .   

  • Before Stringer went in with the hoseline, the normally-assigned Lieutenant showed up told him he could leave now.  Stringer declined the offer, saying “I got it”, and went inside.  The ensuing collapse killed him and Ankum.

Worcester Cold Storage Warehouse Fire 1999

3 comments

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

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

The Worcester Six;   

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

   

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

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

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

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

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

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

 

Fireground Operations

    

KEY ISSUES   

Abandoned building left unprotected and unsecured.   

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

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

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

Fire spread via combustible interior finishes.   

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

Delayed fire reporting   

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

Access limitations for fire suppression and rescue.   

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

Unusually long interior travel distances.   

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

    

Exterior Circa 1998

BUILDING HISTORY AND CONSTRUCTION   

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

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

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

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

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

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

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

BUILDING USE   

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

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

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

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

VERTICAL PENETRATIONS   

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

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

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

HORIZONTAL PENETRATIONS   

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

INTERIOR FINISH   

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

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

INTERIOR LAYOUT   

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