30 Dowling Circle

 

On Wednesday, January 19, 2011, a fire occurred in an apartment building located in the Hillendale section of Baltimore County, Maryland. This fire resulted in the line of duty death (LODD) of volunteer firefighter Mark G. Falkenhan, who was operating as the acting lieutenant on Squad 303 . Upon their arrival, FF Falkenhan and a second firefighter from Squad 303 deployed to the upper floors of the apartment building to conduct search and rescue operations. Other fire department units were already involved with both firefighting operations and effecting rescues of trapped civilians.

During these operations, FF Falkenhan and his partner became trapped in a third floor apartment by rapidly spreading fire and smoke conditions. The second firefighter was able to self-egress the building by diving headfirst down a ladder on the front (address side) of the building. FF Falkenhan declared a “MAYDAY” and implemented “MAYDAY” procedures, but was unable to escape or be rescued.

FF Falkenhan was located and removed via a balcony on the third floor in the rear of the building. Resuscitative efforts began immediately upon removal from the balcony, and continued en route to the hospital. FF Falkenhan succumbed to his injuries and was pronounced deceased at the hospital.

The Baltimore County (MD) Fire Department published the Line of Duty Death Investgation Report of the 30 Dowling Circle Fire recently. The report was written by a Line of Duty Death Investigation Team comprised of departmental members, including representatives of the local firefighters’ union and the Baltimore County Volunteer Firemen’s Association.

The following is and executive narrative of  the final report (PDF) on the apartment fire where Volunteer Firefighter Mark Falkenhan sustained fatal injuries. The entire report can be downloaded HERE .

The Baltimore Sun newspaper published an editorial about the death of Firefighter Falkenhan that is required reading; HERE . An excerpt from the editorial reads as follows:

FF Mark Falkenhan

 

The word “hero” gets used too often to describe the most pedestrian of admirable behaviors, from the star quarterback who marches his team for a winning score to the kid who finds a missing wallet and turns it in. But exceptional bravery, special ability, exceptional deeds and noble qualities — those are what define an authentic hero, and Mr. Falkenhan lacked for none of them.

It was not by accidental circumstance or naiveté that he ended up on the third story of that Hillendale apartment complex in the midst of a fire, searching for missing residents. He knew the risks as well as anyone could. But his selfless desire to help others drove him forward into the flames.

That’s what made him exceptional. That’s why his legacy is important. That’s why the community is in his debt.

 Incident Executive Summary

On Wednesday, January 19, 2011, a fire occurred in an apartment building located in the Hillendale section of Baltimore County, Maryland. This fire resulted in the line of duty death (LODD) of volunteer firefighter Mark G. Falkenhan, who was operating as the acting lieutenant on Squad 303 (for purposes of this report, Mark will be referred to as FF Falkenhan). Upon their arrival, FF Falkenhan and a second firefighter (FF # 2) from Squad 303 deployed to the upper floors of the apartment building to conduct search and rescue operations. Other fire department units were already involved with both firefighting operations and effecting rescues of trapped civilians.

During these operations, FF Falkenhan and FF # 2 became trapped in a third floor apartment by rapidly spreading fire and smoke conditions. FF # 2 was able to self-egress the building by diving headfirst down a ladder on the front (address side) of the building. FF Falkenhan declared a “MAYDAY” and implemented “MAYDAY” procedures, but was unable to escape or be rescued. FF Falkenhan was located and removed via a balcony on the third floor in the rear of the building. Resuscitative efforts began immediately upon removal from the balcony, and continued en route to the hospital. FF Falkenhan succumbed to his injuries and was pronounced deceased at the hospital.

Baltimore County Fire Department Standard Operating Procedures, Personnel #16, requires a team to be formed, a detailed investigation to be conducted and a report produced for any incident involving a line of duty life threatening injury or death. The team’s objective is to thoroughly analyze and document all the events leading to the injury or death and to make recommendations aimed at preventing similar occurrences in the future. At a minimum, a Division Chief, the Department’s Health and Safety Officer, a member from the Fire Investigation Division, an IAFF Local 1311 union representative, and the Baltimore County Volunteer Firemen’s Association Vice President of Operations (when a volunteer member is involved) is required (see Acknowledgements section for actual team make-up).

The investigating team examined any and all data available, including independent analysis of the self contained breathing apparatus (SCBA), turnout gear and autopsy report. The Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) produced a fire model to assist with evaluating fire behavior. Multiple site inspections were conducted. Extensive interviews were conducted by the team which also attended those conducted by investigators from the National Institute for Occupational Safety and Health (NIOSH). Photographic and audio transcripts were also thoroughly analyzed. A comprehensive timeline of events was developed. All information used to make decisions regarding recommendations was corroborated by at least two sources.

  • In fairness to those units involved in this incident, the investigating team had the advantage of examining this incident over the period of several months. Furthermore, given the size and nature of the event, and the fact that arriving crews were met with serious fire conditions and several residents trapped and in immediate danger, all personnel should be commended for their efforts for performing several rescues which prevented an even greater tragedy.
  • The team did not identify a particular primary reason for FF Falkenhan’s death.
  • What were identified were many secondary issues involving but not limited to crew integrity, incident command, strategy and tactics, and communications.
  • These issues are identified and discussed, and recommendations are made in appropriate sections of the report, as well as in a consolidated format in the Report Appendix.

Some of the issues identified in this report may require some type of change to current practices, policies, procedures or equipment. Most, however, do not. Specifically, the analysis and recommendations regarding Incident Command and Strategy and Tactics show that if current policies and procedures are adhered to, the opportunity for catastrophic problems may be reduced.

  • Mark Falkenhan was a well-respected and experienced firefighter.
  • He died performing his duties during a very complex incident with severe fire conditions and unique fire behavior coupled with the immediate need to perform multiple rescues of victims in imminent danger.
  • It would be easy if one particular failure of the system could be identified as the cause of this tragedy.
  • We could fix it and move on. Unfortunately it is not that simple.
  • No incident is “routine”. Mark’s death and this report reinforce that fact.

 

 

Incident Summary

On Wednesday, January 19, 2011 at 1816 hours, a call was received at the Baltimore County 911 Center from a female occupant at 30 Dowling Circle in the Hillendale section of Baltimore County. The caller stated that her stove was on fire and the fire was spreading to the surrounding cabinets. Fire box 11-09 was dispatched by Baltimore County Fire Dispatch (Dispatch) at 1818 hours consisting of four engine companies, two truck companies, a floodlight unit, and a battalion chief. All units responded on Talkgroup 1-2.

The location, approximately one mile from the first dispatched engine company, is a three story garden-type apartment complex, with brick construction and a composite shingle, truss supported roof. The fire building contained a total of six apartments divided by a common enclosed stairway in the center with one apartment on the left and one to the right of the stairs.

 

Alpha, Bravo, Charlie, and Delta will be used to designate the clockwise geographic locations of the structure, beginning with Alpha on the address side of the building . Entry is gained through the front split-level stairwell by a common entrance door with individual doors leading to each apartment. Each apartment consists of two bedrooms, a kitchen, bathroom, and a living/dining area. There are sliding doors leading to either a wood joist deck/balcony on the second and third floor apartments, or a concrete patio on the first floor apartments. Utilities consist of gas service to the furnace and hot water heaters located in a utility closet in each apartment, with electric service to the remainder of the appliances, including the stove. Interior walls of the apartments are drywall over wood stud construction.

Floor coverings consist of carpeting over tile and concrete on the terrace/first floor. The second and third floor coverings consist of carpeting covering hardwood floors with a plywood subfloor. Interior doors are hollow wood construction. The door to the common hallway is of solid wood construction. The sliding doors to the deck/patio area are glass.

Building Construction

The development and construction of the Towson Crossing Apartments began in the early 1980’s. The buildings are rated in the existing building code for occupancy as Residential 2 (R2). The building code would describe the construction type as Type III. This construction type includes those buildings where the exterior walls are of non-combustible materials and the interior building elements are of any material permitted by the building code.

Building Construction and Features

The subject apartment building, 30 Dowling Circle, is a three story, middle of the group, apartment building constructed on a reinforced concrete slab. The Alpha and Charlie exterior walls are wood framed construction with brick veneer attached by brick ties. The Bravo and Delta exterior walls are block masonry construction and separate adjoining apartment buildings. The interior partition walls consist of wooden 2″x4″ wall studs covered with sheetrock. Paper faced insulation is found between the exterior walls, ceilings and party-walls that separate the apartments.

The apartment building contains six individual apartment units, which are approximately 1000 square feet in size per apartment unit. Two separate units are located on each floor and consist of two bedrooms, a living area, a dining area, a kitchen, and a bathroom. A utility closet is located in each of the living areas. The closet is located along the Alpha wall, and contains the water heater and furnace.

The building is not equipped with an automatic fire suppression system. Smoke detectors were noted; however, it is unknown if they were operational at the time of the fire. A fire extinguisher was noted on the landing between the second and third floor levels of the building.

Topography

From side Alpha the building has two and a half stories above grade while side Charlie is three stories above grade.

The first floor of the building is approximately five feet below ground level with a 20 foot set back from the apartment building parking lot. Side Charlie of the building is at ground level but slopes upward approximately 8 feet with a set-back of 110 feet from the rear alley.

Roof

The roof is constructed of a lightweight truss assembly consisting of 2″x6″ stringers connected by gusset plates. The truss assembly is covered with 5/8 inch plywood and asphalt shingles.

Floor and Ceiling

The floor assembly consists of 2×10 inch floor joists covered by plywood, wooden tongue and groove planking and finished with carpet. The joists run from Alpha to Charlie and are supported by the interior bearing walls. The kitchen floors in all of the units are covered with vinyl tile.

The ceilings throughout the building are sheetrock nailed to the floor joists of the  apartment above with the exception of the third level in which the sheetrock is nailed to the roof joists.

Balconies

The balconies are located on side Charlie of the building. The balconies located on levels two and three consist of 5/4″ deck boards over 2″x10″ wooden joists. The joists are cantilevered off of the floor/ceiling assemblies of levels one and two. The first floor balconies are made of concrete and are at ground level. All balconies are accessible through a single pane sliding glass door located in each apartment.

 

 

 Incident Overview

The first arriving engine, E-11, was staffed with a Captain, Lieutenant, Driver/Operator, and a Firefighter. Upon arrival at 1820 hours, the Captain gave a brief initial report describing a three story garden apartment with smoke showing from side Alpha: “The Captain of E-11 will have Command and we are initiating an aggressive interior attack with a 1 ¾” hand line”. Command also instructed the second due engine to bring him a supply line from the hydrant. 

A female resident (victim # 1) appeared in a third floor apartment window, Alpha/Bravo side (Apt. B-1), yelled for assistance, and threatened to jump. Smoke or fire was visible from any of the third floor windows. At 1823 hours, Command advised Dispatch that he had a rescue and that he was establishing Limited Command. Fire Dispatch was in the process of upgrading the response profile to an apartment fire with rescue when the responding Battalion Chief requested that the fire box be upgraded to a fire rescue box. While the Firefighter and Lieutenant prepared for entry into the building, the Captain and Driver/Operator extended a ladder to the 3rd floor apartment window and rescued the resident. The first attempt by the Firefighter and Lieutenant to make entry into the side Alpha entrance was unsuccessful due to the extreme heat and smoke conditions.

Initial Arrival Conditions

The second due engine, E-10, arrived at 1823 with staffing of a Captain, Lieutenant, Driver/Operator, and a Firefighter. At 1823, E-10’s crew brought a 4″ supply line to E-11 from the hydrant at Deanwood Rd. and Dowling Circle and assisted the first-in crew with fire attack.

  • The Captain from E-10 conferred with Command and was instructed to advance a second 1 ¾” hand line.
  • The window to the first floor right apartment (Apt. T-2) was removed, and the second 1 ¾” line was advanced to the building by the crew of E-10.
  • Fire attack was initiated through the removed window. At 1827, Command requested a second alarm.

At this time, heat and smoke conditions just inside the front door improved enough to allow the Firefighter and Lieutenant from E-11 to make entry through the front door and into the stairwell. There they encountered heavy, thick black

smoke and high heat conditions coming up the stairs from the terrace level apartment. The Lieutenant reported that the doorway to the first floor apartment was orange with fire and he had to fight his way through heavy heat and smoke conditions to attack the fire in the first floor right apartment (Apt. T-2). Entry was made approximately 3 feet into the doorway when the Firefighter’s low air alarm began to sound, and he exited the building. A member from E-10’s crew replaced the Firefighter from E-11 on the hose line.

At the same time, the Captain from E-11 proceeded to the rear of the structure to complete his initial 360 degree size up. He noted that there was fire emanating from the open sliding doors on the first floor Charlie/Delta apartment (Apt. T-2), extending to the balcony above. E-1, staffed by a Captain, Driver/Operator, and two Firefighters arrived and completed the hookup of the supply line that had been laid to the hydrant by E-10. The rest of Engine 1’s crew grabbed tools and an extension ladder and reported to the Charlie side of the building.

Personnel stated that at this point fire conditions seemed to improve, suggesting that crews were making progress extinguishing the fire. (The first arriving attack crew reported that they were able to see apparatus lights through the sliding doors on Charlie side, which indicated to them that smoke and fire conditions were improving.)

Truck 1, a tiller unit staffed by a Lieutenant, two Driver/Operators, and a Firefighter, arrived on side Alpha and immediately began search and rescue operations. Windows on the second floor Alpha/Delta side apartment (Apt. A-2) were vented and ladders were thrown to gain access. T-8 arrived at the alley on side Charlie. E-1 extended a ground ladder to the third floor balcony on the Charlie/Bravo side of the structure (Apt. B-1), and made access to the apartment to search for additional victims.

  • They noted fire venting from the first floor Charlie/Delta apartment (Apt. T-2) out of the sliding glass doors progressing upwards towards the balcony on the second floor. Upon entering the apartment, they conducted a primary search and noted minimal heat with light smoke conditions.
  • The crew accessed the hallway via the apartment entry door and noticed an increase in the temperature and the amount of smoke.
  • They immediately closed the door and exited the apartment via the ground ladder.
  • Upon exiting the apartment, E-1’s crew observed E-292 on the scene with a hand line extending into the apartment of origin, (first floor, Charlie/Delta side, Apt. T-2). The officer on E-1 noted white smoke coming from the unit.

Having already laid a supply line from the intersection of the alley and Deanwood Road, E-292’s crew extended a 1 ¾” hand line into the apartment of origin. Moderate fire conditions with zero visibility were encountered, and they reported feeling a great deal of heat on their knees as they crawled through the apartment.

The Lieutenant and the Firefighter from Truck-1 entered Apartment A-2 via a second floor bedroom window (Alpha/Delta side) and began a search for additional victims. As they traversed the living room area they found an unconscious male resident (victim #2). At 1836 hours, the Lieutenant notified Command via an urgent transmission that a victim had been located and they needed assistance with evacuation. The Lieutenant and Firefighter noted a small fire in the rear corner near the victim as they exited the room. The crew returned to the bedroom from which they had entered and closed the door behind them. Victim #2 was then evacuated from the apartment via a ground ladder through the bedroom window, and transferred to EMS personnel on side Alpha.

Preflashover conditions Alpha Side 18:37 hours

At 1831 hours, Squad 303, a unit staffed by a Driver/Operator, Firefighter Falkenhan (acting Officer in Charge), and 3 other Firefighters had arrived at the Alpha side of the building. Firefighter Falkenhan and two crew members grabbed their tools and immediately entered the building. One Firefighter (Firefighter #1) proceeded to the terrace floor apartment to assist crews with fire attack. Firefighter Falkenhan and the other Firefighter (Firefighter #2) proceeded to the second floor

Bravo side apartment (Apt. A-1) to search for additional victims. They forced the door to the second floor apartment and conducted their search. Finding no one, they reported to Command that they had encountered high heat in the apartment and at 1838 hours, inquired as to which apartment victim #2 had been found. Firefighter Falkenhan advised Command that he and his fellow Firefighter were proceeding to the third floor to continue their search.

At 1840 hours, Battalion Chief 11 (BC-11) arrived on the scene, performed a face-to-face pass on with the Captain on Engine 11, and assumed Command. BC-11 initially observed limited smoke conditions, indicating to him that crews had made progress in extinguishing the fire.

18:41 hours

Meanwhile, the Lieutenant and Firefighter from T-8 entered the second floor apartment that S-303 had just searched (Apt. A-1, second floor, Bravo side). They proceeded through the apartment and went across the hallway to Apartment A-2 where Truck-1 had just made their rescue (second floor, Delta side).

The Lieutenant noted smoky conditions, and saw that the sliding doors to the rear of the apartment were open, and saw a small fire in the rear of the apartment to the left of the open doors. On their way back to their point of entry, T-8’s crew discovered an unconscious female victim (victim #3). At 1837 hours, T-8 attempted to reach Command via radio and was covered by inaudible radio traffic. Dispatch was able to receive the radio transmission from T-8, and advised Command that another victim had been located on the second floor.

  • At this point, the crew from S-303 had completed their search of the third floor Bravo side apartment (Apt. B-1).
  • Firefighter Falkenhan and Firefighter #2 were able to look out of the sliding doors on side Charlie down to the first floor apartment, Apt. T-2 (Charlie/Delta side) and could see fire.
  • Smoke conditions on the third floor were light enough to walk upright in a somewhat crouched position.
  • The crew returned to the hallway, forced open the door to the third floor Charlie/Delta side apartment, Apt. B-2, and made entry.
  • Firefighter #2 walked down the hallway to the bedroom on the right while Firefighter Falkenhan searched to the left. After checking the bedroom, Firefighter #2 stated that he heard something behind him and turned to see fire in the hallway.

As the crew from S-303 searched the third floor Delta side apartment (Apt. B-2), The Lieutenant and Firefighter from T-8 were attempting to remove victim #3 from the second floor Delta side apartment (Apt. A-2). As they prepared to move their patient, fire conditions changed suddenly.

The Lieutenant from T-8 observed fire, “…rolling over our heads and out of the apartment door.” An immediate increase in heat conditions was noted. Upon exiting the apartment, T-8’s crew described a “tunnel of fire” coming out of the apartment and into the hallway. At 1841 hours, a radio transmission was made by an unknown source that heavy fire was observed in the hallway through a window at the stairwell landing.

At the same time, (1841) one minute after his arrival, Battalion Chief-11 (Command) noted heavy black smoke coming from the building and observed a “flash” through a second floor window. Command immediately ordered an evacuation of the building. Dispatch sounded the evacuation tones over the radio, and repeated the order to evacuate. Engines on the scene sounded their air horns to indicate that the order to evacuate had been given.

Firefighter #2 from S-303 reported hearing the engines on the fire ground sound their air horns, indicating to him that he needed to leave the building. Smoke conditions in the apartment had changed to thick black smoke, and the fire intensified, blocking his means of egress from the bedroom.

Realizing that he needed to get out of the apartment quickly, Firefighter#2 crawled to a window on the Alpha side of the bedroom and signaled Firefighters below with his hand light to move a ladder to the window. Crews immediately moved the ladder, and at 1841, Firefighter#2 dove headfirst out of the window and down the ladder, where he was assisted by crews working on the exterior of the building.

  • At 1841, Firefighter Falkenhan declared, “Emergency” on his radio, and repeated the same seven seconds later.
  • Command immediately queried S-303 for his location and the transmission “I’m down to the floor, heavy fire” was heard. At 1842 hours, Dispatch sounded emergency tones and restricted the Talkgroup to communications only between S-303 and Command.
  • Seconds later Firefighter Falkenhan again keyed up his portable radio and advised “…trapped on the 3rd floor, heavy fire on the Alpha/Bravo.”
  • Fourteen seconds later he advised “I hear crew members, the third, MAYDAY, MAYDAY, MAYDAY.”
  • Command notified Dispatch, “We have a MAYDAY” and was interrupted by a transmission from Firefighter Falkenhan, “urgent.”
  • Command made several attempts to contact Falkenhan to ascertain his location and determine resources needed (Location Unit Name Assignment Resources) for rescue.

Upon hearing the MAYDAY, crews on side Charlie threw multiple ladders to the third floor balcony to assist with rescue.

Heavy heat, smoke, and fire conditions made rescue difficult, but Firefighter Falkenhan was located and removed from the apartment via the balcony to the extended aerial ladder from T-8. He was unconscious and unresponsive at this time. Resuscitative efforts began immediately upon removal from the balcony, and continued enroute to the hospital. Firefighter Falkenhan succumbed to his injuries and was pronounced deceased at the hospital.

 

 

Consolidated List of Recommendations

Crew Integrity

1. Company officers shall ensure that crew integrity is maintained at all times by all personnel operating in an IDLH environment. 2. No personnel shall operate in an IDLH environment without a portable radio.

MAYDAY

1. If possible, the firefighter should activate his/her Emergency button on the portable radio. 2. Once personnel have called a MAYDAY and provided the information needed (LUNAR), they will activate their PASS Device manually and intermittently.

Incident Command

1. Tactical Operations Manual 07 allows Incident Commanders the flexibility to adapt to fast-moving and complex incidents. When re-assuming command, the IC must be identified (verbally through Fire Dispatch) to allow units involved and responding to know who is in command.

2. Incident Commanders must understand that an early initial 360° would give the IC the information needed to develop effective strategy and tactics for incident mitigation.

3. Additional arriving units must give the IC an updated report on fire conditions when noticeably different than those announced in the Brief Initial Report.

4. Arriving units should prompt the IC to assign them supervision of a division when conditions warrant such action.

5. The IC must ensure that all division and group supervisors are properly deployed and verbalize same on the radio for Dispatch and units involved on the incident.

6. Reinforce the importance of the ICS and its functional components for all officers.

7. Ensure a manageable span-of-control is maintained throughout the incident.

8. Evaluate the efficiency of command and control as incidents escalate.

9. A Rapid Intervention Team is a vitally important part of the ICS and its assignment should not be overlooked.

Strategy and Tactics

1. Use caution when passing a hydrant that is in your direction of travel and close to the fire building in an attempt to get a closer one.

2. Consider having the initial backup line proceeding into the same point of entry as the initial crew operating in the IDLH environment. Doing this allows for the line to also aid in protecting the common stairwell (i.e. fire extension/protection for egress). Deploy a third line if needed into another point of access.

3. Consider dialing nozzles up to higher gallons per minute for large structures such as apartment buildings.

4. Consider utilizing a 2-1/2″ attack line for fire attack.

5. The current SOP should be modified to state that when the initial Incident Commander feels that the incident has stabilized to a point where there is no longer a need for him/her to be directly involved with incident operations, a notification through Dispatch shall be made to inform crews on and en route to the scene.

6. The Department should develop training to ensure that Incident Commanders relay changes in modes of operations.

7. Consider attacking fires from other sides of the structure that are on grade.

8. Consider the use of “door control” for protection during search and rescue and exposure protection

9. When deviations to initial orders are made, they must be communicated to Command.

10. IC should consider setting up a division supervisor with the first arriving officer to balance his/her span-of-control early into the incident.

11. Command should initiate group and division supervisors early into an incident and use them to reduce his/her span-of-control. Communicate Conditions, Actions, Needs (CAN) reports early and often.

12. When units are the initial crews deployed to a geographic location, consideration should be given to “prompt” Command to make them a division supervisor (in the absence of direction from Command).

13. Units should request resources, or supply their own as necessary to support the operations that they are undertaking.

14. When given a division assignment, “step back” to take in the overall picture and communicate progress reports to Command.

15. Be clear and concise when setting up division assignments.

16. Utilize the division supervisors for incident operations once assigned.

17. Training on effective use of interior doors to control fire spread should be promoted throughout the department.

18. Consider removing common stairwell windows earlier in fire ground operations when appropriate.

19. While performing operations above the fire, notify Command of changing conditions and immediately request resources to support your function.

20. Set up a command post as early as possible to aid in deploying and accounting for resources as they arrive on the fire ground.

21. Notify Command when entering an IDLH.

22. Request resources to support functions.

23. Set up divisions and groups early to aid in managing the strategic priorities.

24. Be clear in communicating strategy and tactics to companies involved in operations.

25. Command should make it a priority to deploy attack lines on all floors to support the operations of crews working in the area.

Communications

1. A rubberized cover for the radio speaker microphone should be tested by communications and field personnel. This device will cover the push-to-talk (PTT) button and will increase the pressure required for activation. If proved effective, this cover will decrease the likelihood of an accidental activation of the PTT button during vigorous fire ground activity.

2. Continuing study should occur to evaluate methods to control inadvertent radio interference from all units (on the scene, responding, or monitoring) during incident operations. Review PTT logs to identify sources of communications interference.

3. As a result of the investigation, PTT log files will now be saved for 25 days.

4. Fire Communications and field personnel will develop and distribute a mandatory training program outlining proper radio procedures including the importance of radio discipline, MAYDAY procedures, and the procedure for establishing a Command restricted talk group during critical operations.

5. All personnel engaged in operations in an environment immediately dangerous to life and health shall carry a portable radio.

6. The aforementioned mandatory training program shall stress the importance of giving regular updates to Command regarding the extent and location of the fire and other pertinent information.

Structural Collapse Fire Tests: Single Story, Wood Frame Structures

A series of fire tests was conducted in Phoenix, Arizona to collect data for a project examining the feasibility of predicting structural collapse. The fire test scenario was selected as part of a training video being prepared by the Phoenix, Arizona Fire Department. Multiple fires were started in each structure to facilitate collapse; the fires were not intended to test the fire endurance of the structures. Four structures with different roof constructions were used for the fire tests. Temperatures were measured as a function of time in four locations within each structure. Furniture items were placed in the front and back of each structure to simulate living room and bedroom areas. The living room and bedroom areas of each structure were ignited simultaneously using electric matches. Peak temperatures obtained during the tests ranged from approximately 800 °C (1500 °F) to 1000 °C (1800 °F). The roof of each structure collapsed approximately 17 minutes after ignition. In addition to the full scale tests, the plywood and oriented strand board (OSB) roofing materials were tested using a cone calorimeter to characterize the fire properties of the materials.

Structural Collapse Fire Tests: Single Story, Ordinary Construction Warehouse

Two fire tests were conducted in a warehouse located in Phoenix, Arizona to develop data for evaluation of a methodology for predicting structural collapse. A firewall was constructed to divide the warehouse into two fire compartments. Temperatures were measured as a function of time in three locations during the first test and in two locations during the second test. In addition, the volume fraction of carbon monoxide was measured at selected locations during each test. Stacks of wood pallets were used as the primary fuel source and were ignited using paper and an electric match. Some combustible debris and the building structural elements provided the remainder of the fuel load. Peak temperatures obtained at different elevations ranged from approximately 300 °C (570 °F) to 800 °C (1470 °F). Peak carbon monoxide volume fraction reached 4 % in the first test and 5 % during the second test. The roof of the front half of the structure burned through approximately 18 min after ignition of the fire for the first test. The roof of the back half of the structure burned through about 15 min after the start of the second test.

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

Between the years 1979 and 2002 there were over 180 firefighter fatalities due to structural collapse, not including those firefighters lost in 2001 in the collapse of the World Trade Center Towers. Structural collapse is an insidious problem within the fire fighting community. It often occurs without warning and can easily cause multiple fatalities.  

As part of a larger research program to help reduce firefighter injuries and fatalities the U.S. Fire Administration (USFA) funded the National Institute of Standards and Technology (NIST) to examine records and determine if there were any trends and/or patterns that could be detected in firefighter fatalities due to structural collapse. If so, these trends could be brought immediately to the attention of training officers and incident commanders and investigated further to determine probable causes.

REPORT

Trends in Firefighter Fatalities Due to Structural Collapse 1979-2002


Collapse Prediction Technology

A field-based monitoring technique that utilizes measurements of fire-induced vibration was developed and first demonstrated under a previously funded research effort. This report details the findings of the ensuing 3-year endeavor in which significant improvements were made to both field-test and analysis procedures. A real-time monitoring tool has been developed and numerous full-scale burn tests on a variety of structures have been completed. A significant contribution of the research stems from the use of system stability theory to aid in the interpretation of the field measurements.

Residential Fire in Prince George’s County (MD) Injures Seven Firefighters: Wind Driven Conditions Suspected  

Apparent wind driven condition contributed to rapidly escalating fire conditions resulting in extreme fire behavior during initial fire suppression operations being coordinated at a single family residential dwelling (SFD) fire Friday night February 24th in Riverdale, MD. At 9:11 p.m. firefighters responded to a house fire in the 6404 57th Avenue, according to published reports and the new release from Prince George’s County (MD) Firefighters.

PGFD companies arrived to find a one-story with basement, single-family home with fire on both levels. A review of public records indicates the SFD was built in 1967 of dimensioned wood frame construction consisting of a single story with a full basement with 780 square feet of occupied floor space.  The house foot print was approximately 30 feet x 26 feet and had a low profile gable roof. A review of building (birdseye view) aerial images suggests that a moderate grade change from the Alpha division to the Charlie division is apparent with  walk-in basement access.

Firefighters initiated an interior attack from the Alpha Division when an apparent sudden rush of air fanned by high winds entered from the rear of the house (Delta Division), either from a door or window being opened or broken out, the news release said.

The rapid influx of air from the sustained winds into the interior room compartments combined with the already progressing fire conditions creating a “fire ball’ within the structure’s interior rooms where companies were operating engulfing the firefighters. Firefighters tried to escape and commanders immediately called for an EMS Task Force and Fire Task Force.

 

 

 

A review of internet published archival weather data for the general area (Riverdale/College Park, MD) during the period of 20:55 hrs. and 21:15 hrs., recorded wind speeds of 13.8 – 20.7 MPH with wind gusts of 27.6 – 36.8 MPH. gusts of  MPH. (wunderground.com HERE)

 

 

At this time two firefighters, Bladensburg Volunteer Fire Fighters Ethan Sorrell and Kevin O’Toole remain in critical condition at Washington Hospital Center.  A third fire fighter, Riverdale Volunteer, Michael McLary also remains hospitalized for injuries.  Four other injured fire fighters, three from Riverdale and one from College Park, were released and sent home last night according to the latest reports.

  • NIST 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

Updated 02/26/2012

From Statter911: Here’s what Chief Bashoor told The Washington Post’s J. Freedom du Lac about the fire:

Strong winds were gusting out of the west at the time — “up to 40, 45 mph,” said the chief. They were blowing directly at — and into — the burning basement, which had a west-facing door.

“As soon as the guys opened the front door and advanced, it blew from the basement, up the steps and right out the front door,” Bashoor said. “It was like a blowtorch coming up the steps and out the door.”

The entire incident — “from the time they were in the door until they were burned” — took eight seconds, the chief said.

The firefighters inside the house “did everything they were trained to do,” he said, but they were essentially defenseless.

“Without that wind, the hot air and gases would have been venting out of the rear of the house,” he said. “The current of air essentially produced a chimney right up the steps and out the front door.”

 The Chief of the Department directed the Department Safety Officer to conduct a Safety Investigation of this incident. The primary purpose of the investigation was to identify and analyze the contributing factors that led to the incident as well as to create situational awareness to prevent future occurrences. The main objective of the Team’s investigation and subsequent report was to discover the key factor that led to the fatal outcome of two Firefighters. The SFFD report contains the findings and recommendations to help prevent Firefighter injuries or fatalities in the future.

 

In analyzing and recording these events, the Investigation Team acknowledges and respects that members confronted a challenging situation. On‐scene personnel reacted quickly to the changing conditions at this incident. We request that every person who reads this report show respect, appreciation and consideration for all personnel who responded to this incident.

As is a common industry practice, for this report Lieutenant Vincent Perez was referred to as Victim 1 and Firefighter Paramedic Anthony Valerio was referred to as Victim 2, with the exception of the Rescue Events Section.

 Excerpt from Chief of Department’s Letter

“On Thursday, June 2, 2011 at 10:45 a.m., the San Francisco Fire Department responded to Box 8155, at 133 Berkeley Way. What was seemingly a routine working fire in a single family residence quickly transformed into a fierce and unrelenting incident with ultimately tragic results.

When we answered the call to a career in the Fire Service and took our Oath of Allegiance, we were aware of the inherent danger of our occupation. Despite this awareness, we do not expect to encounter a line of duty death of a brother or sister, especially not in our very own Department. The profound loss of Lieutenant Vincent Perez and Firefighter/Paramedic Anthony Valerio has left an indelible impression in our hearts and will forever be remembered in the annals of SFFD history.

Even as we mourned our fallen brothers in the early days after the tragedy, our Department began the painful and difficult, but necessary, steps of a Line of Duty Death investigation. We were resolute in understanding what occurred during those fateful minutes and compelled to uncover any recommendations for improvement that may arise to future operations so that their passing will not have been in vain. For over six months, the Investigative Team worked tirelessly, scrutinizing every piece of evidence in order to produce a comprehensive report.”

Executive Summary and Report Excerpt

On June 2, 2011 at 10:45 hours, the San Francisco Fire Department was dispatched to a report of a fire in the building at 133 Berkeley Way in the City’s Diamond  Heights neighborhood. The first unit arriving on the scene, Engine 26, observed light smoke showing from the garage of the 4 story (2 above grade, 2 below grade) wood framed building, detached on the Bravo side.

 

Aerial from the Charlie Side

An aggressive interior fire attack was initiated through the front door, which is on a level between the ground level and second floor. After investigating the garage (ground level), Engine 24, the second Engine on the scene, led a small line through the garage to the interior door to back up the first Company. Battalion 9 was assigned Fire Attack by Battalion 6, who had assumed Command. Battalion 9 entered the fire building and, after conferring face to face with Engine 26 on the first floor (ground level), concluded that the fire was below them.

 

Alpha Side Operations

Battalion 9 exited the building and proceeded to the Bravo side to check for an entrance leading directly to the fire floor. Engine 11 led a large line wye to the driveway with the intention of leading a 1 ¾ inch line through the garage. They were redirected by Battalion 6 to make their lead down the Bravo side of the building to Sublevel 1 (one floor below grade) to assist Battalion 9. The Division Chief, upon arrival, assumed Command. He assigned Battalion 6 to Division 3 (ground floor).

Truck 15 was assigned Roof Division. Truck 11 split their crew, two members to the roof and three members to search and ventilate the top floor of the fire building. The Rescue Squad was ordered to conduct a search. Two members initially attempted to make entry through the garage but, due to extreme heat conditions, redeployed and entered through Sublevel 1 on the Bravo side.

The other two members of the Rescue Squad made entry through the front door, were pushed back by the heat and then made a successful second effort and conducted a search of the top floor.

 

In the course of fireground operations, members of several Companies came upon the stricken members on the first level and removed them from the building. All possible efforts were employed to revive the members and they were transported to San Francisco General Hospital (SFGH). One member (Victim 1) succumbed to his injuries that day and the second member (Victim 2) succumbed to his injuries two days later. Two other Firefighters were treated at SFGH for various injuries and released that day.

The Medical Examiner determined the cause of death for both members was due to complications from external and internal thermal injuries. Both victims suffered burns to 40% of their body surface. This fire was determined to be accidental by the SFFD Fire Investigative Unit. The fire originated on Sublevel 1, on the West side of the family room, near the large floor to ceiling windows. The ignition was a non‐specific electrical sequence in the electrical wiring or appliance (handheld vacuum cleaner) in this area.

There was a delay in reporting the fire due to the occupants’ attempting to extinguish it on their own. (SFFD Fire Investigation Report 11‐0500532)

The investigation identified that the failing of the window on Sublevel 1, located near the seat of the fire and directly across the stairwell leading to the ground floor, led to the extreme fire behavior which ultimately caused the death of two Firefighters. This fire was in a stage of deprived oxygen when the window failed, causing a rapid extreme high heat event to occur. The extreme heat followed the natural flow path up the interior stairs where Victims 1 and 2 were located.

The Safety Investigation Team found no conclusive evidence that the members were exposed to direct flame impingement during this rapid extreme heat event. However,

Victims 1 and 2 received varying degree of burns up to 40% of their body. The investigation concluded that this was caused by the rapid extreme heat conditions that radiated through their Personal Protective Equipment (PPE) to their bodies. These temperatures exceed the ability for human survival regardless of PPE.

The PPE was inspected and evaluated by NIOSH and the manufacturer. Both reviewing parties concluded that the PPE performed to its specifications and design. The manufacturer concluded that the PPE was exposed to temperatures in the range of 550‐ 700°F. These extreme temperatures were short in duration which caused limited damage to the outer shell of the PPE.

The Safety Investigation Team noticed severe heat damage to the portable radios remote speaker/microphones on Victims 1 and 2 and had the radios tested. The testing indicated that the remote speaker/microphones failed to operate correctly due to heat damage. The Safety Investigation Team was not able to determine, after testing, exactly when the remote speaker/microphones failed. The investigation has shown that multiple attempts were made to contact Engine 26 with no response.

The investigation also found that no radio transmissions of distress were received from Victims 1 or 2. Command and Control of any incident in the San Francisco Fire Department is acquired and maintained through the use of the Incident Command System (ICS).

The Incident Command System provides the tools for clear objectives, a single action plan, clear and acknowledged communications, and accountability for all members assigned to an incident. At this incident, some of the components of Incident Command System that were not followed include:

  • Single action plan
  • Fireground Accountability

From these findings, this report makes recommendations for several areas of the Department, including:

  • Training
  • Equipment
  • Policy Development
  • Policy Enforcement

The Safety Investigation Team gathered and analyzed many facts and conducted interviews of members directly involved in this incident. The Team identified several factors that occurred that contributed to the deaths at this incident.

These factors include:

  • Extreme heat conditions accelerated by the failure of a window on the fire floor.
  • Layout of building
  • Excessive live fuel load which contributed to the growth of the fire

Conclusion

This incident appeared from the onset to be a routine “room and contents” fire that the SFFD encounters on a regular basis. As the Companies were performing standard fireground operations, the incident rapidly deteriorated due to a hostile fire event. The failure of a window in the fire room allowed fresh oxygen to enter the room, providing a fire that was deprived of one of the key elements of combustion to rapidly intensify.

Due to the growth of the fire, the room flashed, causing extreme and rapid heat conditions which traveled up the interior stairs (the flow path) to the location which our members were operating. Our members were caught in this high heat, causing the injuries that ultimately claimed their lives.

Due to this fire event, other Companies attempting to conduct fireground support operations were prevented from making entry into the structure from street level (through garage) to back up Engine 26. These Companies were forced to regroup and find an alternate point of entry. In the process of doing so, crews made entry from the Bravo side directly into the fire room and extinguished the fire. This allowed members to make entry from above which led to the discovery and rescue of our members.

These events happened in a time frame of less than fourteen minutes.

 During the course of this investigation, the Safety Investigation Team recognized that no matter how experienced or properly prepared we are, we must always approach all incidents with the utmost awareness.

This incident showed that a simple failure of a piece of glass/window caused unforeseeable and fatal consequences.

We, as a Department, need to gain further knowledge and understanding of the following:

  • Having Situational Awareness prior to taking action, this would include the ongoing process when conditions change
  • How Risk Management must be used when making all decisions
  • Limitations of the PPE (turnouts, SCBA, and equipment)
  • Building construction, including layout and how fire/smoke will
  • move within the structure
  • Ventilation practices and how they affect fire conditions
  • Importance of Communications for all members operating on the scene
  • Companies must use strict discipline when assigned task/locations

Looking Back at One Meridian Plaza High Rise Fire: 1991

No comments

One Meridian Plaza Fire 1991, Provided Photo Source Not Known, All rights reserved

On what began as an uneventful Saturday night twenty-one years ago, a fire on the 22nd floor of the 38-story Meridian Bank Building, also known as One Meridian Plaza, was reported to the Philadelphia Fire Department on February 23, 1991 at approximately 2040 hours and went on to burned for more than 19 hours.

The fire caused three firefighter fatalities (LODD) and injuries to 24 firefighters.

PFD Line of Duty Deaths:

  • Captain David P. Holcombe, age 52
  • Firefighter Phyllis McAllister, age 43
  • Firefighter James A. Chappell, age 29

 The 12-alarms brought 51 engine companies, 15 ladder companies, 11 specialized units, and over 300 firefighters to the scene. It was one of the largest high-rise office building fire in modern American history –completely consuming eight floors of the building –and was controlled only when it reached a floor that was protected by automatic sprinklers.

  • The Fire Department arrived to find a well-developed fire on the 22nd floor, with fire dropping down to the 21st floor through a set of convenience stairs.
  • Heavy smoke had already entered the stairways and the floors immediately above the 22nd.
  • Fire attack was hampered by a complete failure of the building’s electrical system and by inadequate water pressure, caused in part by improperly set pressure reducing valves on standpipe hose outlets.

Wind Driven Fires

Wind Driven Fires

Wind blowing into the broken window of a room on fire can turn a “routine room and contents fire” into a floor-to-ceiling firestorm. Historically, this has led to a significant number of firefighter fatalities and injuries, particularly in high-rise buildings where the fire must be fought from the interior of the structure.

Wind-Driven Fire in a Ranch-Style House in Texas, 2009

On April 12, 2009, a fire in a one-story ranch home in Texas claimed the lives of two fire fighters.  (NIOSH REPORT HERE) Sustained high winds occurred during the incident.  The winds caused a rapid change in the dynamics of the fire after the failure of a large section of glass in the rear of the house.

NIST performed computer simulations of the fire using the Fire Dynamic Simulator (FDS)  and Smokeview, a visualization tool, to provide insight on the fire development and thermal conditions that may have existed in the residence during the fire.

The FDS simulation that best represents the witnessed fire conditions indicates that the fire that spread throughout the attic and first floor developed a wind driven flow with temperatures in excess of 260 °C (500 °F) between the den and front door.  The critical event in this fire was the creation of a wind-driven flow path between the upwind side of the structure and the exit point on the downwind side of the structure, the front door.  The flow path was created by the failure of a large span of windows in the den, in the rear of the structure.  Floor-to-ceiling temperatures rapidly increased in the flow path where multiple crews were performing interior operations.  In a simulation that excluded wind, the flow path was not created, and the thermal environment surrounding the location of interior operations was improved.

Wind has been recognized as a contributing factor to fire spread in wildland fires and large-area conflagrations and wildland fire fighters are trained to account for the wind in their tactics.  While structural fire departments have recognized the impact of wind on fires, in general, the standard operating guidelines for structural fire fighting have not changed to address the hazards created by a wind driven fire inside a structure.  The results of the “no-wind” and “wind” fire simulations demonstrate how wind conditions can rapidly change the thermal environment from tenable to untenable for fire fighters working in a single-story residential structure fire.

The simulation results emphasize the importance of including wind conditions in the scene size-up before beginning and while performing fire fighting operations and adjusting tactics based on the wind conditions.  These results are in agreement with NIST studies conducted to examine wind driven fire conditions in high-rise structures.

LESSONS  LEARNED

Based on the analysis of this fire incident and results from previous studies, adjusting fire fighting tactics to account for wind conditions in structural fire fighting is critical to enhancing the safety and the effectiveness of fire fighters.  Previous studies demonstrated that applying water from the exterior, into the upwind side of the structure can have a significant impact on controlling the fire prior to beginning interior operations.  It should be made clear that in a wind-driven fire, it is most important to use the wind to your advantage and attack the fire from the upwind side of the structure, especially if the upwind side is the burned side.  Interior operations need to be aware of potentially rapidly changing conditions.

Career Probationary Fire Fighter and Captain Die as a Result of Rapid Fire Progression in a Wind-Driven Residential Structure Fire – Texas

SUMMARY

Shortly after midnight on Sunday, April 12, 2009, a 30-year old male career probationary fire fighter and a 50-year old male career captain were killed when they were trapped by rapid fire progression in a wind-driven residential structure fire. The victims were members of the first arriving company and initiated fast attack offensive interior operations through the front entrance. Less than six minutes after arriving on-scene, the victims became disoriented as high winds pushed the rapidly growing fire through the den and living room areas where interior crews were operating. Seven other fire fighters were driven from the structure but the two victims were unable to escape. Rescue operations were immediately initiated but had to be suspended as conditions deteriorated. The victims were located and removed from the structure approximately 40 minutes after they arrived on location.

Key contributing factors identified in this investigation include: an inadequate size-up prior to committing to tactical operations; lack of understanding of fire behavior and fire dynamics; fire in a void space burning in a ventilation controlled regime; high winds; uncoordinated tactical operations, in particular fire control and tactical ventilation; failure to protect the means of egress with a backup hose line; inadequate fireground communications; and failure to react appropriately to deteriorating conditions.

NIOSH investigators concluded that, to minimize the risk of similar occurrences, fire departments should:

  • ensure that an adequate initial size-up and risk assessment of the incident scene is conducted before beginning interior fire fighting operations
  • ensure that fire fighters and officers have a sound understanding of fire behavior and the ability to recognize indicators of fire development and the potential for extreme fire behavior (such as smoke color, velocity, density, visible fire, heat)
  • ensure that fire fighters are trained to recognize the potential impact of windy conditions on fire behavior and implement appropriate tactics to mitigate the potential hazards of wind-driven fire
  • ensure that fire fighters understand the influence of ventilation on fire behavior and effectively apply ventilation and fire control tactics in a coordinated manner
  • ensure that fire fighters and officers understand the capabilities and limitations of thermal imaging cameras (TIC) and that a TIC is used as part of the size-up process
  • ensure that fire fighters are trained to check for fire in overhead voids upon entry and as charged hoselines are advanced
  • develop, implement and enforce a detailed Mayday Doctrine to insure that fire fighters can effectively declare a Mayday
  • ensure fire fighters are trained in fireground survival procedures
  • ensure all fire fighters on the fire ground are equipped with radios capable of communicating with the Incident Commander and Dispatch

Additionally, research and standard setting organizations should:

  • conduct research to more fully characterize the thermal performance of self-contained breathing apparatus (SCBA) facepiece lens materials and other personal protective equipment (PPE) components to ensure SCBA and PPE provide an appropriate level of protection.
  • Although there is no evidence that the following recommendation could have specifically prevented the fatalities, NIOSH investigators recommend that fire departments:
  • ensure that all fire fighters recognize the capabilities and limitations of their personal protective equipment when operating in high temperature environments.

Chicago Fire Department: Everyone Goes Home (official version)

The Chicago Fire Department: Everyone Goes Home

NFFF News Release: In an effort to  make personal safety a  top priority, the National Fallen Firefighters Foundation (NFFF) and the Chicago Fire Department (CFD) today released a new video, Chicago Fire Department – Everyone  Goes Home®.  Members of the CFD and families of fallen firefighters share their stories in this compelling and moving testimonial of the importance of adhering to safety standards and accepting personal responsibility for following procedures.

Chicago Fire Commissioner Robert Hoff was impressed by a video that the NFFF and the Fire Department of New York produced several years earlier to educate members about the importance of training and safety standards. The FDNY leadership had noticed behavioral improvement among its members following the release of their video. Hoff felt that the members of the CFD could benefit from hearing first-hand accounts of the lessons learned by their colleagues and invited the NFFF to collaborate on a video for Chicago.

“The culture of firefighting requires us to do everything we can to make sound decisions so we can be in a position to help the people we serve when they most need it,” said Ronald J. Siarnicki, executive director of the NFFF. “With this video the firefighters and leadership of the Chicago Fire Department are clearly showing the rest of the fire service you can still be a firefighter and at the same time do your best to make sure Everyone Goes Home®.”

FDNY Brooklyn Box 4080: 17 Vandalia Avenue 12.18.1998

Take a moment to look back at an incident: On December 18, 1998, Three FDNY Firefighters died in-the line of duty while conducting suppression and rescue operations at  fire on the tenth floor of 10-story high-rise apartment building for the elderly.  At 0454 hours Brooklyn transmitted box 4080 for a top floor fire at 17 Vandalia Avenue in the Starrett City development complex. The sprawling complex is located on Brooklyn’s south shore in the Spring Creek section. The 10 story 50 x 200 fireproof building is used as a senior citizen’s residence. Engine 257 and ladder 170, both quartered in Canarsie, were assigned 1st due and arrived within 4 minutes. By that time the fire already could be seen blowing through two windows. Second and 3rd alarms were quickly transmitted.

As the 1st due Ladder Company, L170′s duty is to search the fire floor. Lieutenant Joseph Cavalieri, and fire fighters Christopher Bopp and James Bohan ascended 10 flights of stairs with extinguishers and forcible entry tools. Their mission was to rescue the resident of apartment 10-D who was believed trapped inside.

NIOSH INVESIGATIVE REPORT SUMMARY (F99-01) On December 18, 1998, several fire companies and fire fighters responded at 0454 hours to a reported fire on the tenth floor of a 10-story high-rise apartment building for the elderly. The fire had been burning for 20 to 30 minutes before it was called in because the resident attempted to put the fire out with small pans of water. As the fire fighters approached the building from the rear, an orange glow was observed in the window of Apartment 10D. As the fire fighters were arriving in front of the high-rise, a call was received from Central Dispatch that a female resident in the apartment next door to the fire apartment was trapped in her apartment and needed help. Several fire fighters entered the lobby area, and some took the stairs to the ninth floor, while others took the elevator to the ninth floor. A Lieutenant and two fire fighters on Ladder 170 (the victims), along with the Lieutenant on Engine 290, took the B-stairs from the ninth floor to the tenth floor, and entered the hallway, in search of the fire, while 4 fire fighters on Engine 290 were flaking out the hose line on the ninth floor and in the stairwell between the ninth and tenth floor in preparation for hookup.

During this same time period, other fire fighters had gone to the tenth floor A-stairwell landing to attempt a hose line hookup to the standpipe in the landing. Engine Company 257 fire fighters, who were attempting to make a hook-up on the fire floor landing, experienced trouble with the heat, heavy smoke, and heavy insulation on the standpipe and were forced to abandon this hook-up. The Lieutenant on Engine 290 and the victims, who were on the B-side, were approaching the center smoke doors (see diagram), when the Lieutenant radioed his driver on the outside, and asked, “Where is the fire?”

The driver radioed back, the fire is in the rear, towards exposure 4. The Lieutenant on Engine 290 then left the tenth floor, descended the stairs to the ninth floor and helped his men drag the hose to the A-stairwell, where they met up with fire fighters on Engine 257, who assisted them in stretching their line and hook-up on the ninth floor. The victims proceeded through the center smoke doors in search of the fire. From the information obtained during this investigation, it is believed the victims found the fire apartment, with the door partially opened, allowing smoke and hot gases to enter the hallway. They then opened the door fully, the wind pushed the fire and extreme heat in the apartment into the hallway, and a flashover occurred, exposing the victims to extreme radiant heat that potentially elevated their body core temperature.

The last radio transmission from the victims was a Mayday call. When the victims were found, all were unresponsive, they were treated at the scene and taken to the hospital where they were pronounced dead by the attending physician.

This wind-driven fire event and the lessons-learned contributed directly to the current body of research and new insights on emerging strategies and tactics.

Remembering Brackenridge 1991 Floor Collapse and LODD

Remembering Brackenridge, Pennsylvania December 20, 1991: Four Firefighters Killed, Trapped by Floor Collapse

Four volunteer firefighters died when they were trapped by a partial floor collapse during a structure fire in Brackenridge, Pennsylvania, on the morning of December 20, 1991. All four were members of a mutual aid truck company that had responded to the early morning incident and were assigned to prevent fire extension from the basement to the ground floor of a 2-story building.

Although they were wearing full protective clothing and using self-contained breathing apparatus, it appears that they were overwhelmed by the severe fire conditions that erupted when a section of the ground floor collapsed into the basement.

The collapse cut off their primary escape path, and the fire burned through their hose line, leaving them without protection from the flames.  

SUMMARY OF KEY ISSUES

  • Situation: Fire in enclosed room in basement. Unable to locate fire because of smoke. Smoke and heat increasing, but no visible fire.
  • Structure: Appeared to be heavy concrete construction. Actually thin concrete floors supported by unprotected steel.
  • Contents: Furniture refinishing business. Quantities of flammable finishes and solvents in basement.
  • Exits: One entrance/ exit on each level; no alternate exits.
  • Structural Collapse: Floor section collapsed between interior crew and their only exit. Fire overwhelmed crew.
  • Rescue Attempts: Valiant rescue efforts proved unsuccessful. Unsure if missing members fell into basement or were trapped on ground floor.
  • Incident Command: No formal command system or personnel accountability in place. Chief of first-due company in command of incident; Assistant Chiefs assigned to basement and ground floor.
  • Information: No pre-fire plan and no detailed knowledge of occupancy. Clues of structural danger not recognized as fire conditions increased
  • Communications: Radio system inadequate for current needs.
  • Response: Independent volunteer companies. Mutual aid requested on arrival and additional companies called in succession.
  • Weather: Extremely cold night, predawn hours. Problems with frozen hydrants.
  • Water System: Weak supply. Extensive mutual aid and long relays needed to protect exposures.

The analysis of this incident provides several valuable lessons for the fire service. Unfortunately these are all revisited lessons, not new discoveries. These firefighters died in the line of duty, while conducting operations that appeared to be routine, and were unaware of the situation that was developing below them. They died in spite of the fact that they were experienced, they were operating with a standard approach to operational safety, and they were the object of repeated rescue attempts by highly capable comrades.

There are several factors that could have provided warning or changed the outcome of this situation. Like most accidents, this situation was the result of a number of problems that came together under the worst possible circumstances. Firefighting obviously involves inherent dangers that must be accepted by its practitioners. The important messages for the fire service are to identify risk factors in advance of an incident and to develop mechanisms to react appropriately when critical situations present themselves.

This situation bears distinct similarities to other incidents that have claimed the lives of several firefighters in the past. The lessons that must be derived from this incident are not a condemnation of the actions or judgment of anyone who was involved in the situation; they simply identify information that can help to prevent this type of accident from occurring in the future.

Remembering

Buffalo Box 191 North Division & Grosvenor Streets; December 27, 1983

Buffalo Box 191

As Buffalo (NY) firefighters arrived at the scene of a reported propane leak in a three-story radiator warehouse (Type III Ordinary and Type IV Heavy Timber construction), a massive explosion occurred, killing five firefighters instantly and injuring nine others, three of them critically.

The force of the blast blew BFD Ladder 5′s tiller aerial 35 feet across the street into the front yard of a dwelling. BFD Engine 1′s pumper was also blown across the street with the captain and driver pinned in the cab with burning debris all around them. Engine 32′s engine was blown up against a warehouse across a side street and covered with rubble.

The Same Mistakes: Newspaper Reports Common Issues Affecting Fire Operations

No comments

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

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

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

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

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

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

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

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

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

High-rise fires cause quarter billion dollars of property damage a year

No comments

High-rise fires cause quarter billion dollars of property damage a year
  

The National Fire Protection Association (NFPA) is reporting that in 2005-2009, there were an average of 15,700 reported structure fires in high-rise buildings per year with an associated $235 million in direct property damage.

The report, “High-Rise Building Fires,” (PDF, 499 KB) cites apartments, hotels, offices, and facilities that care for sick as accounting for roughly half of all high-rise fires. Structure fires in these four property classes resulted in $99 million in direct property damage per year.

There is a downward trend in high-rise fires. In the last few decades, a range of special provisions have migrated into the codes and standards for tall buildings.

Other findings from the report:

  • In 2005-2009, high-rise fires claimed the lives of 53 civilians and injured 546 others, per year.
  • The risks of fire, fire death, and direct property damage due to fire tend to be lower in high-rise buildings than in shorter buildings of the same property use.
  • An estimated three percent of all 2005-2009 reported structure fires were in high-rise buildings.
  • Usage of wet pipe sprinklers and fire detection equipment is higher in high-rise buildings than in other buildings of the same property use.Most high-rise building fires begin on floors no higher than the 6th story.  The risk of a fire is greater on the lower floors for apartments, hotels and motels, and facilities that care for the sick, but greater on the upper floors for office buildings.

 In 2005-2009, an estimated 15,700 reported high-rise structure fires per year resulted in associated losses of 53 civilian deaths, 546 civilian injuries, and $235 million in direct property damage per year. An estimated 2.6% of all 2005-2009 reported structure fires were in high-rise buildings.

The trends in high-rise fires and associated losses (inflation-adjusted for property damage) are clearly down, but the sharp post-1998 reduction appears to be mostly due to the change to NFIRS Version 5.0, which is shifting estimates to lower levels that also appear to be more accurate.

Four property classes account for roughly half of high-rise fires: apartments, hotels, facilities that care for the sick, and offices. In 2005-2009, in these four property classes combined, there were 7,800 reported high-rise structure fires per year and associated losses of 30 civilian deaths, 352 civilian injuries, and $99 million in direct property damage per year. The property damage average is inflated by the influence of one 2008 hotel fire, whose $100 million loss projected to nearly $40 million a year in the analysis.

The report emphasizes these four property classes.

Some other property uses – such as stores and restaurants – may represent only a single floor in a tall building primarily devoted to other uses. Some property uses – such as grain elevators and factories – can be as tall as a high-rise building but without a large number of separate floors or stories.

  • For these reasons, the four property use groups listed above define most of the buildings we think of as high-rise buildings, and their fires come closest to defining what we think of as the high-rise building fire problem.
  • By most measures of loss, the risks of fire and of associated fire loss are lower in highrise buildings than in other buildings of the same property loss.
  • This statement applies to risk of fire, civilian fire deaths, civilian fire injuries, and direct property damage due to fire, relative to housing units, for apartments, and risk of fire for hotels, offices, and facilities that care for the sick.

The usage of wet pipe sprinklers and fire detection equipment is higher in high-rise buildings than in other buildings, for each property use group. Even so, considering the extensive requirements in NFPA 101®, Life Safety Code, for fire and life safety features in both new and existing high-rise buildings, it seems clear that there are still major gaps, particularly in adoption and enforcement of the provisions requiring retrofit of automatic sprinkler systems and other life safety systems in existing high-rise buildings. NFPA 1®,Fire Code, has sprinkler retrofit requirements.

This has implications for public officials and ordinary citizens in any city. Public officials should make sure that the latest editions of NFPA 1®, Fire Code, and NFPA 101®, Life Safety Code, are in place and that the codes they have are supported by effective code enforcement provisions, including plan review and inspection processes, both for new construction and for continued supervision of code compliance in existing buildings.

The public can take responsibility for their own safety by insisting that their public officials take these steps. As in so many areas of fire safety, we know what to do, but we still need to do it.

The trend had been toward a smaller share of fires being reported each year as occurring in buildings with fire-resistive construction, both for high-rise and other buildings, with the decline being most dramatic in facilities that care for the sick.

  • This statistical decline could reflect any or all of the following:
  • (a) a shift in construction between the two types permitted by codes, from Type I (442 or 332) construction, which is coded as fire-resistive, to Type II (222) construction, which is coded as protected non-combustible;
  • (b) a shift to acceptable alternative designs using more sprinklers and less fire-resistive construction; or
  • (c) enough success in containing fires that a rising fraction never are reported to fire departments, because the fires are caught and controlled so early by occupants.

 Most high-rise building fires begin on floors no higher than the 6th story. The fraction of 2005-

2009 high-rise fires that began on the 7th floor or higher was 32% for apartments, 22% for hotels and motels, 21% for facilities that care for the sick, and 39% for office buildings. The risk of a fire start is greater on the lower floors for apartments, hotels and motels, and facilities that care for the sick, but greater on the upper floors for office buildings.

  • High-rise apartments have a slightly larger share of their fires originating in means of egress than do their shorter counterparts (4% vs. 3%).
  • The same is true of hotels (7% vs. 5%) and facilities that care for the sick (6% vs. 4%).
  • In offices (4% vs. 6%), the differences in percentages are in the opposite direction, which means that high-rise buildings in those properties have a smaller share of their fires originating in means of egress.
  • In all four property classes, the differences are so small that one can say there is no evidence that high-rise buildings have a bigger problem with fires starting in means of egress.

Residential Building Estimates

Definition of Residential Building


A structure is a constructed item of which a building is one type.

The term residential structure commonly refers to buildings where people live. To coincide with this concept, the definition of a residential structure fire includes only those fires confined to an enclosed building or fixed portable or mobile structure with a residential property use.

Such fires are referred to as residential buildings to distinguish these buildings from other structures on residential properties that may include fences, sheds, and other uninhabitable structures.

  • Residential buildings include, but are not limited to one- or two-family dwellings, multifamily dwellings, manufactured housing, boarding houses or residential hotels, commercial hotels, college dormitories, and sorority/fraternity houses.

SFFD Diamond Heights LODD Safety Violations

2 comments

State investigators have cited the San Francisco Fire Department for “serious” worker safety violations in the deaths of two firefighters killed battling a Diamond Heights house fire in June. Reports were published in the San Francisco Chronical, HERE  and HERE.

 Firefighters lost track of Lt. Vincent Perez, 48, and firefighter-paramedic Anthony Valerio, 53, after they went into the four-level home at 133 Berkeley Way on June 2 and failed to respond quickly to the men’s last radio communication, investigators with the state Department of Industrial Relations’ Division of Occupational Safety and Health said in a report issued Monday.

In recommending that the Fire Department be fined $21,000, the state investigators also said the department had violated state rules requiring that two firefighters be designated outside to assist any two firefighters who venture into a life-threatening environment.

Only one firefighter from Perez and Valerio’s engine company – the first on the scene – was available to come to their help during the blaze, the investigation found.

The state also cited the Fire Department for an incident – evidently before the fatal flareup – in which an unidentified battalion chief ventured into the burning building alone, without keeping in contact with Perez and Valerio. That was also deemed a serious violation of safety rules.

“These are serious in that they had protocols in place, but they weren’t following them,” said Erika Monterroza, spokeswoman for the worker safety agency. “There’s no question that a lack of communications was a big issue here. The investigator found there was a breakdown there.”

Fire Chief Joanne Hayes-White said the department would appeal the findings. She said state officials have told her commanders that the violations fell short of finding the department’s actions responsible for the two firefighters’ deaths. “None of the citations involved a direct cause of the line-of-duty deaths,” Hayes-White said. Monterroza confirmed that, saying the exact circumstances of the firefighters’ deaths could not be determined.

Valerio, Perez and a third member of Engine Company 26 in Diamond Heights were the first firefighters to arrive at the mid-morning blaze, which started when a sparking electrical outlet set curtains on fire.

The third firefighter manned the pumper hose while Valerio and Perez went inside to fight the fire, but the safety regulations require a fourth firefighter to be available outside to assist.

A scene commander, identified by firefighters as Battalion Chief Thomas Abbott, ordered a crew from Engine Company 24 to back up Valerio and Perez inside the building. For several minutes, however, scene commanders tried to find the Engine 26 firefighters, without success.

There was an unspecified gap between that last communication and any effort by firefighters to respond over the radio or track down the men, the state investigation found.

The reports goes on to state that Hayes-White said the department’s investigative report – still in draft form – concluded that the fire had melted one of the firefighters’ microphone cords, cutting off communications. She said any delay in firefighters’ response would be addressed in the final report.

Firefighters ultimately found Perez and Valerio in a landing area and carried the injured men outside. Perez was pronounced dead at San Francisco General Hospital, and Valerio died there two days later.

The state probe also faulted the actions of the unnamed battalion chief who went into the building “alone and also did not remain in contact with the firefighters who were inside.”

Hayes-White said the battalion chief had gone inside only briefly, had seen Perez and Valerio alive and had never been out of other firefighters’ view.

Today December 3, 2011 marks the 12th anniversary of the Worcester Cold Storage Warehouse fire that resulted in the line of duty death of six courages brother firefighters.   

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

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.   

   

Bridging The Gap: Fire Safety and Green Buildings Guide

Bridging The Gap: Fire Safety and Green Buildings Guide

A Fire and Safety Building Guide to Green Construction

The National Association of State Fire Marshals (NASFM) has released its fire and building safety guide to green construction called “Bridging the Gap: Fire Safety and Green Buildings.” This guide identifies some of the key areas where rapidly growing green building construction issues coincide with building and fire safety needs.

“This guide will give both the fire service and the green construction community a reference point for developing buildings and sites that are not only environmentally sound, but also continue to meet fire safety needs,” said NASFM President Alan Shuman. “This will provide a much-needed reference on issues that impact the life safety of building occupants, emergency responders and the larger community.”

Included are topical areas such as Site Selection and Use, Building Envelope and Design Attributes, and Building Systems and Alternative Power Sources. A key feature of the guide is a series of checklists focusing on plan reviews for commercial and residential occupancies. This document is meant as an introductory guide for fire chiefs and firefighters, building and fire code enforcement officials, architects and anyone involved in building design, plan reviews and construction.

Click here to download a copy of the guide, which was developed for NASFM by Jim Tidwell of Tidwell Code Consulting, with Jack Murphy, as part of a larger program under a Department of Homeland Security Fire Prevention and Safety Grant.

Residential Pre-Arrival: What are your Considerations?

No comments

 

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

The large volume hip style (concealed space) roof may have become rapidly charged with elevated temperatures, superheated gases, products of combustion and possibly the initial stages direct flame extension through the eaves and into the truss loft.  Incident scene operations photos depict an engineered structural roof system.

Roof Profile

 

Pre-arrival fire conditions exhibit indicators that suggest the need for the rapid intervention of arriving companies and a coordinated aggressive posture tactically if the incident action plan is formulated to achieve an interior attack. Given the scenario of the backdraft conditions, the likelihood for a degraded or compromised ceiling membrane enclosure (intact ceilings, thus limiting fire extension)  being present will hamper and may be an operational concern for interior operating companies as fire conditions continue to grow in magnitude and severity and full extend and take command of the truss loft enclosure.

These fire conditions will extend into the space, resulting in degradation of the structural components and roof assembly-which will present a high risk potential for isolated or catastrophic collapse. This intrusion into the truss loft would require interior operating company officers to maintain attentiveness towards the effectiveness and progress of tactical suppression and support tasks with the potential for fire quickly dropping into operating areas and affecting firefighter safety.

Coordinated and timely vertical ventilation and roof work may be warranted if part of the normal operating parameters of the fire service agencies. In some areas of the county, vertical ventilation is not considered a tactical functional objective and is not implemented.

Adequate fire flow for suppression must be established early on in the operations, if an interior attack is implemented. Projected fire intensity and severity may challenge initial engine companies if hand lines and fire flow rates and the placement of hose streams are ineffective or marginal.  In the event of master stream operations it would be crucial to ensure interior fire suppression operations are suspended, a transition to a defensive mode is communicated and acknowledge on the fireground with collapse zone considerations.

Operational Considerations

In viewing the video of pre-arrival conditions and fire parameters and indicators; as an arriving company officer or commanding officer, how would you establish your incident action plan (IAP) and establish operations? Present and discuss why you would make these decisions, what is/are the basis?

What would you be considering in the areas of:

  • Building Integrity
  • Collapse Potential
  • Interior Fire Attack Considerations
  • Resource Needs: Staffing and Apparatus
  • Critical Operational Tasks
  • Apparatus Placement
  • Hose Line Placement
  • Safety Considerations  
  • Exposures
  • Contingency Issues: What can go wrong?  

 Assuming you are just arriving on scene and observe the backdraft conditions from the front seat; What would your operational IAP be and why?

Identify and discuss the types of mission critical size-up consideration that must be recognized and processed?

How does apparatus placement affect incident operations?

What first-due operational factors have you experienced that were contingent upon other tasks or considerations that were apparent to you or you implemented?

How does extreme fire behavior and fire dynamics affect your fire ground position?

 How does this scenario and building size and type relate to similar structures and occupancies in your district or mutual aid/greater alarm response area?

Research Agenda Symposium Report Issued

No comments

The Second National Fire Service Research Agenda Symposium

A new report identifies seven critical areas where more research is needed to further reduce the number of firefighters killed or injured in the line of duty. These priorities were developed during the Second National Fire Service Research Agenda Symposium sponsored by the National Fallen Firefighters Foundation (NFFF).

Download the 2011 Report:  May 20 – 22, 2011 – 2nd Research Agenda Symposium

More than 70 representatives from a broad range of fire service-related organizations met over two days at the National Fire Academy in Emmitsburg, Maryland. Their goal, to update the current Research Agenda, a guide for research projects within the fire service. In doing so the following seven areas were identified as research priorities: Community Risk Reduction; Wildland Firefighting; Data Collection; Technology and Fire Service Science; Firefighter Health and Wellness; Emergency Service Delivery; and Tools and Equipment.

More than 70 representatives from a broad range of fire service-related organizations participated

 

The 2nd National Fire Service Research Agenda

The Second National Fire Service Research Agenda Symposium was conducted on May 20 -22, 2011 and was also hosted by NFFF at the NFA campus in Emmitsburg, MD. The project was funded by the National Fallen Firefighters Foundation. The purpose of the second Symposium was to produce an updated edition of the Research Agenda, based on current relevancy, as a guide for future research efforts. Following the model that had been established six years earlier, more than 70 individuals, representing a diverse range of interests participated in the 2011 Symposium.

The participants (who represented 55 different organizations) were asked to self-determine where they would best be able to lend the greatest expertise and guidance, selecting among seven different discussion groups.

Each group was assigned a range of subject matter as their primary area to focus upon; however, it was recognized that the individual domains were broad and the boundaries could not be precisely defined. The groups were encouraged to approach their task with a broad perspective and to seek broad consensus as opposed to narrowly defined priorities. Each group produced a set of recommendations that were reported back to the full assembly for further discussion.

The research areas and the facilitators assigned to each research domain are listed below. The facilitators were chosen based upon their reputations as leaders in their respective areas. They provided leadership for discussion within their groups, and wrote the reports. Kevin Roche of the Phoenix Fire Department was the general facilitator.

  • Community Risk Reduction (Vickie Pritchett, Shane Ray)
  • Wildland Firefighting (Stan Gibson, Nelson Bryner)
  • Data Collection (Lori Moore-Merrell, DrPH)
  • Technology & Fire Service Science (Gavin Horn, PhD, Daniel Madrzykowski)
  • Firefighter Health and Wellness (Murrey Loflin, Sara Jahnke, PhD)
  • Emergency Service Delivery (Christopher Naum, Victor Stagnaro)
  • Tools and Equipment (Bruce Varner, Robert Tutterow)

Participants were divided into discussion groups based on their expertise within one of the seven areas to develop specific research recommendations for each of the topics. Out of this process came 41 recommendations for potential investigation projects.

“The first Research Agenda Symposium was an outcome of Firefighter Life Safety Initiative #7 which directly links a national research agenda and data collection system to firefighter safety,” said Ronald J. Siarnicki, executive director of the NFFF. “The second symposium was convened to assess the changes and advances that had occurred within the fire service over the previous six year and identify new needs and priorities for potential study.”

The updated Research Agenda is intended to provide a reference source and a starting point on where to direct efforts and funding.

The Symposium planning team asked each group to develop a maximum of ten recommendations for presentation to the plenary session on Sunday morning. The groups were also asked to keep their recommendations broad enough so they could be approached from a number of research perspectives and to include the rationale for recommending those particular subjects as research priorities. This proved to be an efficient process reflecting the high level of expertise represented in each group.

The Sunday session began with a discussion of grant programs and funding sources, led by AFG Branch Chief Cathie Patterson. The recommendations of the seven discussion groups were then presented by the respective facilitators for discussion by the full assembly. All of the 41 recommendations that were presented to the plenary session are included in the 2011 Research Agenda report.

The 2011 edition incorporates one significant departure from the 2005 Research Agenda report; the overall ranking of projects on a Priority 1-2-3 scale was omitted and only the priorities established within the individual discussion groups are included. This decision reflects a consensus of the assembled participants that it is extremely difficult and probably unrealistic to apply this type of prioritization process across such a wide range of subject areas.

There was also concern that a 1-2-3 prioritization might encourage researchers and funding organizations to limit their attention to only the highest priorities and thus to overlook the lower ranked topics. The participants wanted to emphasize that all of the identified projects merit attention and should be considered on their own merits. After considerable discussion the group voted to set aside the overall 1-2-3 ranking and asked each group identify one project that should be recognized as an immediate concern.

The number one recommendations are:

  • Community Risk Reduction: Creation of a community-scale model that evaluates fire prevention and response programs and quantifies their ability to produce a potentially positive outcome. This may include (but is not limited to) data pertaining to: occupancy types and numbers of each, fire prevention, codes adoption, mitigation, response, and recovery.
  • Wildland: Development of safe and reliable aircraft operations for suppression and team transportation to reduce Wildland firefighting injuries and fatalities.
  • Data Collection: Identification of cultural perception of data collection / Identification of barriers to capture of quality data.
  • Technology and Fire Service Science: Development of data, implementation of transfer mechanisms and updating of standards that will enable firefighters to learn the science and utilize the technology required to respond to the changing fire conditions in our modern built environment.
  • Health and Wellness: Effectiveness of intervention and screening for health and disease related to firefighter wellness and fitness.
  • Service Delivery: Development of a scientifically-based community risk assessment tool.
  • Tools and Equipment: Assessment of current PPE (entire ensemble) performance, functionality and related safety features for today’s fire environment.

Ultimately, the 41 recommendations contained in this report should serve as a roadmap for all researchers and applied scientists who are interested in firefighter safety and survivability. These recommendations must not be limited for use as AFG guidance only, but should serve as a guidance tool for all who seek grants within their various disciplines. It is also hoped that with these recommendations in hand, other potential research sponsors can be identified and successfully petitioned.

The Report of the Second National Fire Service Research Agenda Symposium is available through the EveryoneGoesHome.com website.

A comments section has been added to the site to collect recommendations for future research from members of the fire service.

Arson Fire now downgraded

No comments

 

 

Updated 11/16/2011; SEE    North Las Vegas Arson No Longer Considered a Booby-Trap

An arson fire in a vacant home in North Las Vegas (NV)  was intention set and devised in a manner to harm firefighters according to Authorities.

Upon arrival of fire companies, the second floor was fully involved with heavy smoke showing from outside the building

North Las Vegas Firefighters and Las Vegas Fire and Rescue worked together to control the flames in the vacant two story home.

It took seven units and approximately 27 firefighters to contain the fire.

There was no extension of the fire to surrounding homes, it was contained in 15 minutes.

There aren’t specific details released on why authorities believe this fire was set to harm firefighters, but the fire official discussing the incident clearly expressed his concerns of what confronted operating companies at this alarm.

Residential Structure Built in 1997

The two story residential structure was of Type V, wood frame construction, built in 1997 consisting of 1,998 Square feet of space with three (3) beadrooms, seven total rooms and an attached garage.

It’s especially important for companies and company officers to remain highly vigilant upon entering and conducting interior operations for any signs or indications that conditions may not be as characteristic and expected for fires in similar occupancies or under prevailing conditions.

We plan to develop and prepare some safety awareness insights for operations in a few days. We’ll also continue to monitor information that may be forthcoming with further details as to what may have been encountered by firefighters.

Los Angeles Firefighters Battle Major Emergency at Townhouses Under Construction

Under-construction building fire forces dozens of evacuations

Operational Divisions with Exposures (Pre-Construction) Bing Maps


 

A townhouse complex under construction caught fire on November 10, 2011, in the Brentwood neighborhood of Los Angeles (CA).  The six-unit, wood-framed complex was in its construction phase, where at least two of the units were fully involved in fire upon arrival of LAFD companies. Four of those six structures were severely damaged as a result of the construction stage and the degree of open wood frame construction resulting in rapid flame spread and extension to a nearby residential buildings.

According to published reports, the Los Angeles Fire Department was called at 3:37 a.m.  to 12315 Gorham Avenue which resulted in a major emergency alarm classification decared and resulted in the dispatch and deployment of over 160 firefighters to the site. First arriving companies found a large townhome development with “heavy fire showing.”

Largely due to an aggressive fire attack by the LAFD, the footprint of this blaze was kept in-check and fully extinguished in one hour and 39 minutes. Fortunately, there were no injuries to any civilians or Firefighting personnel.

Additionally, five adjacent structures were evacuated for precaution. Two of those structures- one, a small apartment complex and the other, a single family dwelling, did sustain significant fire damage. As many as 10 families were displaced from those two occupancies.

Following further investigation, the LAFD stated it believed the fire was intentionally set. 

According to LAFD.Blogspot.com the following  companies were dispatched with Units: E19 RA19 E237 E37 T37 RA37 EM9 BC9 E59 E261 T61 E26 E292 T92 E71 E269 T69 E62 E263 T63 E43 DC3 SQ21 EM14 BC18 BC10 BC4 BC11 BC14 T88 E288 E88 UR88 RA88 RA827 BC5 E63 H6 RA59 RA92 RA71 EM11 E290 AR2 E94 E226 T26 E93 E210 T10 E15 T66 E266 RT59 EA2 EA1 E229 T29 E203 T3 E233 T33 E68 RA17 RA909 RA867 EM17 AR9 AR17 AR11 AR3 T29 E229 T94 E294 E3 E12

Construction Site Operational Considerations (not inclusive)

  • Pre-Fire Plan Large Construction Projects
  • Understand the various Phases to a Construction Project and how they affect fire operations
  • Identify and train for nonconventional Strategic and Tactical operational actions
  • Ensure predetermined multiple alarm resources are identified and greater alarms are established
  • Train your Company and Command Officers to address Construction site fires
  • Maintain an appropriate risk profile balance with operational needs with personnel safety foremost
  • Clearly establish multiple Safety Offices and establish geographical resources within the incident management system for reconnaissance, communications, and oversight and focused safety monitoring
  • Know you water supply and system capabilities and limitations
  • Determine fire flow needs based upon construction phases, as these change over time as the building goes up. Match fire flow demands with resource availability (time of day gaps etc.)
  • Identify exposures (Physical structures and Civilians) and ensure they are calculated into the incident action plan at the right before there are identified needs or concerns
  • Companies shall maintain a conservative safety posture; this is not the time for overly aggressive firefighting, it is the time for smart firefighting that can be highly efficient
  • Always consider collapse zones: partial or complete. Stay out of them!
  • Respect the wind; it’s not going to help you
  • Consider current and projected weather conditions in your operational and tactical plans and assignments
  • Did I already say: Pre-fire Planning?
  • Be calculated in the placement of your apparatus, especially in larger scale incidents that are defined under greater geographical divisions
  • The fire usually consumes the available fuel load rapidly; going from a Huge fire, to one that is sometimes much more manageable; just watch and control your exposures and degree of fire extension.  Don’t help to make the fire even bigger through ineffective and dysfunctional command and control
  • Anticipate, Project, Plan and Engage
  • Respect the Fire: it’s not going to play by the regular rules of combat fire suppression and engagement as in finished and enclosed structures and buildings.

FDNY: Building Collapse Claims Life Of 1 Of 5 Workers Rescued

No comments

Robert Mecea/Associated Press

 
 A five-story building under construction suddenly came down on Monday afternoon in Brooklyn, New York. Three workers became trapped under the rubble after the top two floors fell onto the third, sending it all crashing to the ground, officials said. Published reports indicate that the likelihood of  the weight of the concrete caused the 3rd floor to collapse onto the 2nd floor, resulting in a catastrophic and sequential progressive floor collapse.
 
FDNY companies searched through the pile of concrete, pulling five workers out. Investigators said concrete being poured between the metal pillars buckled the building.
 
The building, at 2929 Brighton Fifth Street, near Neptune Avenue (Brooklyn) fell just before 2:30 p.m. A concrete worker on the site stated according to reports that the collapse happened immediately after concrete from his truck was pumped up onto the second and third floors of the building.
 
Four workers were in the building at the time of the collapse, and one was in front of the building. The one in front refused medical attention.  Firefighters said the framework of the building had been erected, but not much else. Removing the men from the rubble was a delicate and difficult process because of the risk of further collapse. Even after the men were removed, a large piece of corrugated metal hung in front of the building.

Commercials and Collapse Awareness

 

In response to numerous requests from our recent posting; Commercials- Got Fire? Anticipate Collapse briefing post (HERE). We have developed and produced a comprehensive download in PDF format of the entire article that can be used for training, distribution and discussions.

 Click on the image above and download the PDF file and use accordingly  or download HERE

 There are numerous factors to be cognizant of in operations involving commercial buildings and occupancies; with special considerations and a diligent focus on a wide degree of facets on the fireground during combat fire engagement.

You need to start somewhere, thus the investment in these observations and insights for this event. Open your eyes on the fireground, there is so much to take in and respond to; if you know what to look for and can process what you’re seeing.

It is mission critical to comprehend and understand your department’s operational capabilities and the necessary deployment demands for fire suppression, fire flow and phased operations at commercial building fires.

Commercial Fire and Collapse

Respect these buildings for the occupancy risk they present and not the typical occupancy type that we develop our conventional strategies, incident action plans and tactical deployments.

It’s a lot more than that, with far greater consequences; that may be very unforgiving.

 

Commercials- Got Fire; Anticipate Collapse

Got Fire?……Anticipate Collapse..

A recent video clip making its way around the cyber fireground clearly depicted a very close-call and resulting near miss event to four firefighters at a four alarm fire involving a commercial building that housed an established insulation manufacturer and installation contractor.

The video shows within a very compressed time frame, the progression of rapidly deteriorating interior conditions, the adverse affects on the building’s structural systems and the results from the loss of load transfers that lead to a catastrophic wall collapse  narrowly missing the crew of firefighters who were operating a hand line in the vicinity of an exterior overhead door. Fortunately the injuries sustained to the firefighters were minor in nature; however the consequences and results from this collapse could have been far different and significantly more severe.

Following a series of repeated viewings of the video clip and with each successive viewing, it became readily apparent that there was a lot more to these images of the collapse and the cursory focus on the resulting near miss event. Closer examination of the video clip and the still frames brought to light some obvious conditions and indicators that easily become lost in the rapidity of the sequence of the collapse; which really has the true story to be told.

It’s the mechanism and sequence of the collapse, the dynamics of the building’s performance and the building indicators that provide a training opportunity in further examining key factors, presenting insights that could be a focus for operational and command personnel at future incidents with common parameters and gaining some mental models in recognition-primed decision making that contribute to the naturalistic decision-making process.

If you know what to be looking for, then when you see it, you may be able to anticipate, project and implement in rapid succession appropriate measures dictated by the incident.

Four Alarm Commercial Building Fire with Collapse: Fire Photo by Ben Goldberry

 

In an effort to promote additional insights and bring forward these fundamental observations and experienced-based presumptions extended from these and other news video images, still photographs, additional reporting research and examination, and a review of other published media resources; the following observations presented in this overview brief are being conveyed to increase firefighter, company and command level awareness of key collapse indicators such as those present at this commercial fire  and to further the concept of adaptive fireground management principles and increase awareness of fundamental building performance indicators and principles to help you increase your intuitive observations skills and translate them into proactive operational actions on the fireground-before an adverse condition occurs.[ i.e., being five steps ahead of the fire conditions].

Although this briefing makes use of the images and conditions depicted in the video clip and encountered by the fire department evident in the images; the susequent commentary and  insights provided are not meant to provide  direct or indirect opinions, renderings, criticism or censure  towards the conduct of operations or the management of the incident by the respective department and it’s firefighting, command and support personnel who operated at the actual fire and experienced this near miss event first-hand.

We are grateful that the events of this alarm precluded anything worst occurring given the potential seriousness of the prevailing  incident conditions and commend the  fire department and it’s firefighters that provide these exceptional services each and every day to the citizens they serve and to the community they protect, in mitigating this serious fire; safely and successfully.

This incident and the resulting near-miss captured by the videographer provides the Fire Service with an exceptional opportunity given today’s far reaching capabilities of eMedia, this web site and direct and indirect readers, links, tweets, likes, reposting’s, uploads, downloads and sharing  an opportunity to share the consequences of an extreme close-call and learn from it in a positive and constructive manner, so that firefighters, company officers, commanders and support personnel can better predict with knowledge, insight and at times intuition a better understanding of buildings and the structures and occupancies we operate within on the fireground.  

There are numerous inherent indicators present at every incident scene we operate at that. As is in this near miss event and building collapse; it’s sometimes the subtle things that need to gain the attention of operationg companies and personnel and the ability to rapidly process, recognize and react.

 Remember this: Building Knowledge = Firefighter Safety.

As a generality; it’s important to note that given heavy fire involvement in a structure (got fire), adaptive fireground management considerations would promote conservative considerations to anticipate and expect collapse (degraded or compromise; limited or catastrophic).

In the case of fires in commercial occupancies and buildings with;

  • Large Square footage/Floor areas
  • Significant fire loads
  • Large open structural system spans lacking compartmentation, 
  • Unprotected steel components and assemblies 
  • No Sprinkler Systems
  • Omitted, compromised or degraded passive or active protective  or suppression systems
  • Significant openings along the exterior building envelope
  • Significant opening on the roof enclosure
  • Deep seated fires or rapidly escalating and extending fires

It is mission critical to comprehend and understand your department’s operational capabilities and the necessary deployment demands for fire suppression, fire flow and phased operations. 

Respect these buildings for the occupancy risk they present and not the typical occupancy type that we develop our strategies, incident action plans and tactical deployments. Its alot more than that, with far greater consequences that may be very unforgiving.

 

Aerial Plan of Building and Collapse Area A-B

 

The Building

The fire incident involved a single story commercial building occupying approximately 32, 200 square feet of area on a multiple building site with proximal exposures.  Manufacturing, warehousing and offices comprised the building’s operational use.  An aerial plan view shows the geographical building scene divisions and the location and relationship of the Alpha- Bravo Side collapse zones that affected operations and resulted in the close-call and firefighter near-miss. The proximity of exposures, physical layout and orientation can be further assessed.

 

 A review of public documents and records, incident reports and various media resources  provided the following insights;

Overview Details

 

 

Alpha Street Side View- Adapted from Google Streetmaps

 

The view of the alpha street side identifies the building front facade, its main office entrance (center between dual overhead doors on the left and right). Pronounced on the alpha side facade is the presence of four (4) equally spaced overhead (OH) doors that provide direct access into the building’s interior. The subsequent collapse area is depicted at the A-B corner with special attention drawn to relationship of the wall plane and OH door proximity.

The relationship and this wall surface ( area square footage) and the presence of the OH door opening to the wall/ roof interface area that subsequently became compromised and collapsed is critical in further understanding the mechanism of the collapse sequence and also the positive effect it had on the survivability of the firefighters who were within the collapse zone at the time of the wall failure.

Don’t Always Stress the Corners

It’s been a common practice and fundamental fireground consideration to define the corner of a typical building as having safety considerations and prominence in the context of ladder company operations, laddering and roof work and in the placement of personnel and positioning of fireground operations.

Corner Building Operational considerations have included, but limited to;

  • Provides a potentially safe(er) area of operational refuge
  • Provides a location to safely position ground ladders for roof access/egress
  • Provides a location that has a potential  higher degree of assurance for maintaining structural integrity in the event of a collapse condition of an outer wall
  • Will not fail in a catastrophic or monolithic manner due to the postulated presence of structural members on the vicinity of either the wall enclosure and/or the roofing structural system and assemblies
  • The design and construction configuration and orientation of the ninety degree angle of the building’s outer wall envelope (at the corner)  provides predicated inherent structural stability
  • The  typical type of structural or envelope construction may have a resulting  ninety degree building corner having a more robust resistance to collapse and compromise due to the various types of enclosure systems (methods and materials) and assemblies and needed stability per engineering principles

In this instance (as shown in the Alpha side street view),  the presence of the large overhead door in close proximity to the corner wall intersection and transition ( A-B side), actually makes this position, fireground proximity and travel paths highly prone to early and complete collapse potential in the event of a loss of the wall-roof component or assembly integrity or in the load bearing/transfer capabilities of the wall-roof assembly. 

  • The presence and identification of a corner configuration similar to this in a commercial structure should result in a higher degree of considerations and risk assessment when formulation and deploying operational assignments and in the placement of personnel for task assignments in this proximity.
  • This operational area should be considered as a candidate for designation as a collapse zone based upon projected or defined operational considerations, incident conditions and predictive building characteristics, systems, materials and fire dynamics and conditions.  

 

Alpha-Bravo Corner of Subsequent Collapse Aerial View

 
 
The view  from the Alpha-Bravo Corner shows the collapse zones at grade and the affected area size.
 
As noted in the preceding narrative, the presence of the overhead door opening along the perimeter wall enclosure and outer envelope creates a risk area that would require monitoring, periodic reconnaissance and assessment during subsequent operations to determine structural stability and potential adverse conditions.  
 
The proximity of the opening in relationship to the corner wall, roof support and structural span of the opening results in a very delicate balance of forces, loads, reliance and dependence that must be maintained for structural integrity and equilibrium. 
 
  • The entire perimeter of the alpha side could be considered for a restricted collapse zone just in terms of wall opening alone sans the degree of actual or projected interior fire impingement or fire involvement.
 
Take some time to view the video clip a few times over before proceeding to the next sequence of fame images.

 Aerial Overhead view of the building perimeter walls along the four divisions ( A-D) with the A-B corner that subsequently experienced the wall-roof compromise and resulting collapse.

 

 The A-B corner and the affected ground areas around the collapse zone. Considerations for a collapse zone area on the A-B corner would have resulted in a minimum distance of twenty five (25) feet from the building base for all operations within this area. The collapse zone on the Bravo side extends into the exposure building due to its close proximity.

Always consider the building envelope materials of construction and systems present on the building. The use of concrete masonry units (CMU) is common, as is the use of pre-cast concrete and cast-in place and tilt-up concrete construction panels.

Variations in collapse dynamics and mechanisms of collapse may result in sizable increases in collapse zone distances from the building base with consideration for monolithic or partial wall collapse as well as safety considerations for bounce and travel over long distances of modular assembly building pieces ( i.e. concrete blocks, brick venner or material chunks).

We have not discussed collapse considerations for other building envelope systems such as metal panelized systems since these have entirely different collapse considerations and profiling, not applicable to this incident and assessment insights. The same is true when considering operating and collapse considerations at commercial buildings with ordinary construction or heavy timber systems (Type or Class III and IV). These to have different rules of predictive building performance and collapse safety considerations.

 

Typical Interior

 
 
The interior of the building included  unprotected steel components and assemblies consisting of steel columns, beams and open web steel joists. These common and conventional structural support systems provided large free clear spans, common for typical warehouse and commercial occupancies. The presence and operability of  functional fire suppression sprinkler system coupled with passive and active protective devices and compartmentation can help support proactive and aggressive fire suppression efforts in those conditions that have appropriate risk determinations and balanced risk-gain benefits.
 
The presence of unprotected steel components ( Truss, column, structural beams etc. ) and assemblies requires an understanding of the effects of flame and heat impingement,  rate of heat release and fire dynamics, potential for movement and displacement of structural components and effect on assemblies, systems and connections and the effect on structural stability, integrity and building load transfers and displacement that all can adversely affect building performance, integrity and collapse potential  
 
 

Typical Structural System and Components

Typical Open Web Steel Bar Joists w Metal Roof Deck

 

 
Large clear spans provided by the open web steel bar joists allowed for considerable free floor space typical of commercial warehouse occupancies.
Note the use of what appears to be combustible wood storage and staging areas that could have could potentially contribute towards increased fire intensity, extension and further contribute towards adverse affects on the unprotected structural steel components and assemblies.
 

Alpha Side Collapse Area Details: OH Door Pre-Collapse Insights

 
 
 

Pre-Collapse Operations on Alpha side with personnel in close proximty to the building perimeter

 

Pre-Collapse view of Operations on the Alpha side with personnel in close proximity, (within [a] collapse zone) to the building perimeter. It is evident that the degree of interior fire extension and involvement presumes a cautious deployment and placement of personnel in safe operational areas. When operating in such close proximity to the building wall and envelope, it becomes increasingly challenging for company officers and company personnel to monitor overall building performance indicators that may be prevalent or dominant from a view point further away from the building. 

Fire extension, smoke conditions, component or assembly movement or displacement may be readily defined and identified from a vantage point away from the building, requiring additional independent  operational assignments within the division if resources allow.   Otherwise, officers are encouraged to get a big picture view and increase their span of vision of the building and progressing fire conditions and building performance

 
 
 
 

The pre-collapse frame image above identifies the building roof line in relationship to the ground operations, smoke conditions and also the directional flow of the elevated master stream [upper right corner]. The initial  stage of the wall compromise and collapse can be seen in the Bravo wall pulling away. When watching the video, pay close attention first to the stream direction and flow and them at the location and movement of the wall, which is followed in rapid succession with the full wall collapse.

T

 

Close examination of the initial video frames shows the rapid displacement of the portion of the Bravo wall and outward collapse towards the B-Exposure (alleyway) Refer to the Aerial Plan for orientation. The A-B Collapse is progressing from the Bravo side to the Alpha side as loads are being transferred in rapid progression with further collapse expected.

The frame image above shows the bravo wall failing outward with the resulting loss in structural support of the roofing deck assembly.

Rapid fire migration and extension is evident after the wall section collapse with increased flames visible. In the video, one firefighter quickly recognizes the imminent collapse and reacts.

A significant section of wall area is present at the A-B side and progressing from the building corner to the left jamb of the overhead (OH) door. This area and the area directly above the OH door opening is calculated to weigh over 20,000 lbs. 

The early identification and establishment of collapse zone(s) is mission critical especially at commercial buildings due to the considerations for rapidly changing operational conditions that may be a result of or influenced by the following;

  • lack of knowledge or understanding of the building’s construction, systems and characteristics
  • lack of adequate resources, skills and or capabilities for selected phase operations
  • fire loading, combustibles, flammables and other products
  • Last of or loss of compartmentation
  • fire and protective systems failures or inoperability
  • unapproved alterations, additions and renovations to the building, systems and occupancy
  • transitions for offensive to defensive operational phases, which at times may results in operating position postures too close to the building
  • failure to recognize situational factors that will drive appropriate operational phasing and task deployments
  • lack of building performance knowledge
  • not considering occupancy risk versus treating the building/fire relationship based upon occupancy type
  • not recognizing key collapse indicators and failing to implement timely actions [proactively versus reactionary]
  • being four steps behind the fire conditions evident instead of implementing adaptive fire ground management insights [five steps ahead of the evident fire]
  • use precise coordination when placing elevated masterstreams into operations with ground personnel operating within close quarters
  • understand the effects of master streams on the integrity of building features, assemblies and components

 

 
 
 
 
The image frame above shows personnel operating within an imminent collapse zone directing hand lines into the interior fire area. Further examination of the video  frames clearly shows one firefighter quickly recognizing that a collapse is occurring and attempts to alert the other personnel to retreat. Simultaneously to the collapse progression, the crew immediately retreats away from the collapsing wall and falling building materials.
 
Within the span of four seconds, the wall compromise occurs and collapses on the ground at the A-B corner and immediate area on the alpha side.  The slightly monolithic manner in which the wall plane first peels away and progressively collapsed is interesting for a CMU wall. Possibly due to the outward collapse of the Bravo wall, followed by the rapid succession of failure of the roof-wall connection interface resulted in an transitional downward force that pushed the alpha side wall outward allowing gravity to work its force
 
When operating in close proximity to a heavily involved forward interior condition [exterior position] it is important to maintain focused situational awareness and either directly maintain or delegate responsibilities for observations of fire and smoke progress and conditions while monitoring key functional building performance indicators and collapse pre-cursors. 
 
Additionally, always re-evaluate the effectiveness of deployed and operational hose lines, streams and in water application to ensure they are adequate for the degree of fire suppression being undertaken and the corresponding fire flow requirements. Don’t just assume, determine with validity. [ Refer to Tactical Entertainment]  
 
Obscured by the rapidly defining smoke which is a result of the developing and extending collapse, the frame image 04 below depicts the beginning of the compromise and collapse sequence commencing as a result of the Bravo wall compromise and collapse sequence at the B-A corner that will subsequently peel towards the Alpha side and continue up to the outermost jamb of the overhead door.
 
Pay particular attention to the first three to four seconds of the video clip and review the video clip over a few times;  looking at the operating elevated master stream that is clearly visible and operating from the upper right part of the screen through the smoke plume; follow the direct orientation and stream flowing directly towards the bravo wall plane,  and presumed penetrating into/through the roof deck or impacting through the metal roof deck and wall-roof assembly area at the upper roof edge.

 Frame image 04 depicts the rapidly deteriorating conditions that are evident as the collapse sequence continues and the overhead door jamb (left) buckling and adjacent wall failing by way of an outward curl or peel away commencing from the upper (left image) A-B corner at the roof line and then peeling and failing from upper left to right.

The leading edge of the outward collapsing wall plane ( yellow dotted line) is failing with the greatest material concentration occurring at the A-B edge outward. Fortunately the presence and location of the overhead door opening  lessened the amount and location of wall material ( concrete masonry units-CMU) and contributed to a void area being present and not fully impacting the firefighters who were operating within this collapse zone.
 
In other words, had this been a solid full wall collapse likelihood for significant firefighter injury would have resulted. 
 
The affects of wall/roof compromise should be of focused consideration and monitoring when managing incidents of this size and magnitude in similar occupancies and building features.  Flame and heat  impingment can and will affect the structural integrity of lintels spans, beams and truss connects along roof lines and connections. Look for signs of impingment, degradation or compromise. watch for signs of probable inward/outward or curtain wall collapse.

The remaining images, frames 06 and 07 depict the location of the firefighters to the wall collapse, the relationship to the wall and roof system and the degree of wall area that became compromised and collapsed.

This brief video clip and these accompanying briefing insights provided a tremendous opportunity to examine in a non-critical manner an actual near miss collapse event and  operational discernments that provide a focused training an awareness opportunity.

When given the time to analyze and assess, some things become so apparent and self-revealing that we might prematurely say why didn’t someone pick up that or those conditions while conducting operations at [an] incident.  It is dependent on a wide variety of factors, conditions and parameters that are difficult at times to identify and harder yet to fully identify as common or contributing factors, errors or omissions.

It’s not always that easy; but contradictory – some time it really is (or should be) that easy.

Some things on the fireground may not be prone to being so readily identifiable or recognized.

It all depends what you’re looking for and whether you have the necessary insights, knowledge and skill sets. Incident priorities, demands, situational focus, awareness or disconnect all may have a part in how and incident is managed and mitigated.

It goes back directly on knowing what to look for and when; at what type of building with which type of occupancy and under what stage or stages of fire development and combat operations or engagement you might be in. It complex, it takes time and experience and learning’s.

There are numerous factors to be cognizant of in operations involving commercial buildings and occupancies; with special considerations and a diligent focus on a wide degree of facets on the fireground during combat fire engagement.

You need to start somewhere, thus the investment in these observations and insights for this event. Open your eyes on the fireground, there is so much to take in and respond to; if you know what to look for and can process what you’re seeing.

It is mission critical to comprehend and understand your department’s operational capabilities and the necessary deployment demands for fire suppression, fire flow and phased operations. Respect these buildings for the occupancy risk they present and not the typical occupancy type that we develop our conventional strategies, incident action plans and tactical deployments. It’s a lot more than that, with far greater consequences; that may be very unforgiving.
