Leading Causes of Residential Fire Fatalities: Unintentional/Careless Actions, Smoking

No comments

USFA Releases Civilian Fire Fatalities in Residential Buildings (2008-2010) Report “Other unintentionally set, careless” actions and “smoking” are the leading causes
 

The Federal Emergency Management Agency’s (FEMA) United States Fire Administration (USFA) issued a special report today examining the characteristics of civilian fire fatalities in residential buildings. The report, Civilian Fire Fatalities in Residential Buildings (2008-2010) was developed by USFA’s National Fire Data Center and is based on 2008 to 2010 data from the National Fire Incident Reporting System (NFIRS).

According to the report:

  • Ninety-two percent of all civilian fatalities in residential building fires involve thermal burns and smoke inhalation.
  • The leading specific location where civilian fire fatalities occur in residential buildings is the bedroom (55 percent).
  • Fifty percent of civilian fire fatalities in residential buildings occur between the hours of 10 p.m. and 6 a.m. This period also accounts for 47 percent of fatal fires.
  • Thirty-six percent of fire victims in residential buildings were trying to escape at the time of their deaths; an additional 35 percent were sleeping.
  • “Other unintentionally set, careless” actions and “smoking” (each accounting for 16 percent) are the leading causes of fatal residential building fires.
  • Approximately 44 percent of civilian fatalities in residential building fires are between the ages of 40 and 69.
  • Thirteen percent of the fire fatalities in residential buildings were less than 10 years old.

Civilian Fire Fatalities in Residential Buildings (2008-2010) is part of the Topical Fire Report Series. Topical reports explore facets of the U.S. fire problem as depicted through data collected in NFIRS.

Each topical report briefly addresses the nature of the specific fire or fire-related topic, highlights important findings from the data, and may suggest other resources to consider for further information. Also included are recent examples of fire incidents that demonstrate some of the issues addressed in the report or that put the report topic in context.

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.

FDNY Brooklyn Box 4080: 17 Vandalia Avenue 12.18.1998

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.

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

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.

Remembrance: Worcester Cold Storage Warehouse Fire and the Worcester Six

No comments

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.

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.

NFPA releases state-level fire service needs assessment for every U.S. state

No comments

 

NFPA releases state-level fire service needs assessment for every U.S. state.  Findings based on Third Needs Assessment of the U.S. Fire Service with comparisons to earlier studies

The National Fire Protection Association (NFPA) released a fire service needs assessment for each state based on findings from the Third Needs Assessment of the U.S. Fire Service, a study that looked at the current needs of America’s fire departments as compared to those identified in assessments done in 2001 and 2005. The goal of the project was to identify major gaps in the needs of the U.S. fire service and to determine if the Department of Homeland Security Federal Emergency Management Agency’s (DHS/FEMA) Assistance to Firefighters Grant (AFG) programs are continuing to reduce the needs of fire departments.

The report looked at personnel and their capabilities, including staffing, training, certification, and wellness/fitness; facilities and apparatus; personal protective equipment, fire prevention and code enforcement; the ability to handle unusually challenging incidents; and communications and new technologies.

Selected Findings:

  • Nearly half (46 percent) of all fire departments that are responsible for structural firefighting have not formally trained all their personnel involved in structural firefighting, down from 55 percent in 2001 and 53 percent in 2005.
  • Seven out of ten (70 percent) fire departments have no program to maintain basic firefighter fitness and health, down from 80 percent in 2001 and 76 percent in 2005.
  • Nearly half (46 percent) of all fire department engines and pumpers were at least 15 years old, down from 51 percent in 2001 and 50 percent in 2005.
  • Half (52 percent) of all fire departments cannot equip all firefighters on a shift with self-contained breathing apparatus (SCBA), down from 70 percent in 2001 and 60 percent in 2005.
  • Two out of five (39 percent) fire departments do not have enough personal alert safety system devices (PASS) to equip all emergency responders on a shift, down from 62 percent in 2001 and 48 percent in 2005.
  • Except for cities protecting at least 250,000 population, most cities do not assign at least four career firefighters to an engine or pumper and so are probably not in compliance with NFPA 1710, Standard for the Organization and Deployment of Fire Suppression Operations, Emergency Medical Operations, and Special Operations to the Public by Career Fire Departments, which requires a minimum of four firefighters on an engine or pumper.

Third Needs Assessment of the U.S. Fire Service conducted by NFPA concluded: 

  • Needs have declined to a considerable degree in a number of areas, particularly personal protective and firefighting equipment, two types of resources that received the largest shares of funding from the AFG programs.
  • Some innovative technologies that have not been identified as necessary in existing standards but are known to be very useful to today’s fire service – including Internet access and thermal imaging cameras – have also seen large increases in use.
  • Declines in needs have been more modest in some other important areas, such as training, which have received much smaller shares of AFG funds.
  • Still other areas of need, such as apparatus, stations, and the staffing required to support the stations, have seen either limited reductions in need (e.g., apparatus needs in rural areas) or no reductions at all (e.g., adequacy of stations and personnel to meet standards and other guidance on speed and size of response).
  • Fire prevention and code enforcement needs have shown no clear improvement over the past decade.
  • In all areas emphasized by the AFG and SAFER (Staffing for Adequate Fire and Emergency Response) grants, there is ample evidence of impact from the grants but also considerable residual need still to be addressed, even for needs that have seen considerable need-reduction in the past decade.
  • There has been little change in the ability of departments, using only local resources, to handle certain types of unusually challenging incidents, including two types of homeland security scenarios (structural collapse and chem/bio agent attack) and two types of large-scale emergency responses (a wildland/urban interface fire and a developing major flood).

Additional Supplemental

NFPA has conducted a series of national surveys to identify the needs of the fire service for resources required to safely and effectively carry out their responsibilities. The surveys indicated the resources fire departments had, while NFPA codes and standards and other national guidance documents defined the requirements. The gaps between resources in hand and resources required defined the needs. 

These reports look at personnel and their capabilities, including staffing, training, certification, and wellness/fitness; facilities and apparatus; personal protective equipment; fire prevention and code enforcement; the ability to handle unusually challenging incidents; and communications and new technologies. 

All three studies began with requests from Congress, and the first two studies were conducted with and sponsored by the U.S. Fire Administration and its parent agencies.

NIOSH Report addresses Operational Issues at Metal Recycling Facility Fire

1 comment

 NIOSH Report Issue: Seven Career Fire Fighters Injured at a Metal Recycling Facility Fire – California

NIOSH Exective Summary

On July 13, 2010, seven career fire fighters were injured while fighting a fire at a large commercial structure containing recyclable combustible metals. At 2345 hours, 3 engines, 2 trucks, 2 rescue ambulances, an emergency medical service (EMS) officer and a battalion chief responded to a large commercial structure with heavy fire showing. Within minutes, a division chief, 2 battalion chiefs, 3 engines, 3 trucks, 4 rescue ambulances, 2 EMS officers and an urban search and rescue team were also dispatched.

An offensive fire attack was initially implemented but because of rapidly deteriorating conditions, operations switched to a defensive attack after about 12 minutes on scene. Ladder pipe operations were established on the 3 street accessible sides of the structure. Approximately 40 minutes into the incident, a large explosion propelled burning shrapnel into the air, causing small fires north and south of structure, injuring 7 fire fighters, and damaging apparatus and equipment. Realizing that combustible metals may be present, the incident commander ordered fire fighters to fight the fire with unmanned ladder pipes while directing the water away from burning metals. Approximately 2 ½ hours later, two small concentrated areas remained burning and a second explosion occurred when water contacted the burning combustible metals. This time no fire fighters were injured.

Contributing Factors

  • Unrecognized presence of combustible metals
  • Unknown building contents
  • Unrecognized presence of combustible metals
  • Use of traditional fire suppression tactics
  • Darkness

Key Recommendations

  • Ensure that pre-incident plans are updated and available to responding fire crews
  • Ensure that fire fighters are rigorously trained in combustible metal fire recognition and tactics
  • Ensure that policies are updated for the proper handling of fires involving combustible metals
  • Ensure that first arriving personnel and fire officers look for occupancy hazard placards on commercial structures during size-up
  • Ensure that all fire fighters communicate fireground observations to incident command
  • Ensure that fire fighters wear all personal protective equipment when operating in an immediately dangerous to life and health environment
  • Ensure that an Incident Safety Officer is dispatched on the first alarm of commercial structure fires
  • Ensure that collapse/hazards zones are established on the fireground. 

The fire department had a comprehensive list of SOGs and policies. However, the policy for the extinguishment of combustible metal fires was out dated. This policy called for copious amounts of water to be put on the combustible metal fire. The SOG for pre-incident planning was followed at this incident. However, due to the constantly changing business environment, the company had submitted a business plan that identified hazards to the city but this information did not get updated in the computer-aided dispatching (CAD) database for the fire department or dispatch.

A month prior to this incident on June 11, 2010, at 11:00 a.m., the same business owner’s metal processing facility located diagonally across the street from this incident, had several small explosions and fire. This incident required 36 fire department companies, 16 rescue ambulances, 1 USAR team, 2 hazardous material teams, 7 BCs, 1 DC, and a DDC, totaling 248 fire department personnel, in addition to mutual aid. Approximately 2 ½ hours of fire suppression operations with water brought the fire under control, which encompassed a 150′ x 100′ area of combustible metal shavings.

The company had metal –X (a brand of combustible metal fire extinguishing agent) available, but not enough of it to be effective. No fire fighters were injured. However, a civilian worker was critically injured and a police officer received minor injuries.

Fom the LAFD Press Release on July 15, 2010

On Tuesday, July 13th, 2010 at 11:43 PM, 41 Companies of Los Angeles Firefighters, 21 LAFD Rescue Ambulances, 3 Arson Units, 1 Urban Search and Rescue Unit, 1 Rehab Unit, 1 Hazardous Materials Team, 3 EMS Battalion Captains, 8 Battalion Chief Officer Command Teams, 1 Division Chief Officer Command Team and 2 Bulldozers under the direction of Deputy Chief Mario Rueda responded to a Major Emergency Structure Fire at 761 East Slauson Avenue in South Los Angeles (CA).

More than 200 Los Angeles Firefighters were requested over the course of the incident to help battle a blaze at a large two-story commercial structure that encompassed six occupancies over an entire city block. Firefighters quickly arrived at United Alloys and Metals to find heavy fire at an industrial facility known for processing titanium and super alloy scrap.

The 73 year-old structures between Paloma Avenue and Mckinley Avenue, were quickly engulfed in flames and forced firefighters into a defensive attack early during this huge fire fight. Shortly after midnight the decision was made to pull all Firefighters out of the structure and attack the flames from the exterior.

Approximately 20 minutes following this decision a partial wall collapse, roof collapse, and a total of three explosions took place. These massive blasts rained down debris of concrete and titanium on Firefighters and even shattered windows of emergency vehicles.

From this point forward it became a heavy stream operation with ladder pipes and portable monitors that provided huge volumes of water against the intense flames. Despite the challenges of extinguishing burning titanium and the devastating explosions, the blaze was controlled in just five hours. Exhausted Firefighters were relieved the next morning by their colleagues who continued the extended overhaul and detailed salvage procedure. Link HERE

The Structure

The incident involved a 45,000 square foot multiple business commercial structure that measured approximately 300′ x 150′ and was built in 1939. The commercial structure was divided into 3 sections with both Type III and Type V (metal clad) construction. The A-side (west) of the structure measured 60′ x 100′ under a heavy timber bowstring truss roof and exterior block walls covered with a stucco finish. This section of the structure contained denim fabric altering machinery.

The larger 210′ x 150′ open warehouse middle section of the structure was under a metal sawtooth roof (a roof composed of a series of small parallel roofs of triangular cross section, usually asymmetrical with the vertical slope glazed or windowed to allow for light) with concrete reinforced metal beam exterior walls covered with an exterior stucco finish. This section of the structure contained bins, bales, and piles of recyclable metals. The C-side of the structure was an office area that measured approximately 30′ x 150′. It was comprised of two stories with a conventional flat roof, wood framed interior walls, and concrete reinforced metal beam exterior walls covered with an exterior stucco finish.

 

 

Occupancy hazard placards existed at the A and C/D corner of the structure. The placards had a 3 health rating (a serious hazard) in the blue quadrant, a 4 flammability rating (flammable gases, violate liquids, pyrophoric materials) in the red quadrant, a 2 instability rating (a violent chemical change possible at elevated temperatures and pressure) in the yellow quadrant, and an OX (material is an oxidizer) in the white quadrant.

The commercial structure had been recently acquired, within the past year or two, by a local metal recycling company. The company had submitted the annual business plan to the city, which identified potential hazards, but this information had not been updated in the computer-aided dispatch (CAD) database for the dispatch center or fire department. The construction features of the occupancy such as the bowstring trusses, presence of combustible metals, and access restrictions would have been critical information to the fire department for fighting a fire at this location. The fire department had pre-planned the structure prior to the metal recycling company acquiring the commercial structure.

BC11 left the command post and was walking towards T10 and T66 when an upper section of wall on the D-side near the C/D corner collapsed followed by a larger upper midsection of wall on the D-side. BC11 recalled seeing white hot metal and was about to instruct the trucks to direct water away from the white burning metals. Seconds later, approximately 40 minutes into the incident, at 0026 hours, a large explosion propelled burning shrapnel into the air and caused small fires north and south of the structure. T33 and E66′s hoseline crews were blown backwards by the blast. T10 and mutual aid E9 were hit with flaming debris which broke through E9′s driver-side door window and ignited the seat.

T10 received several large dents and wooden ground ladders were ignited. Approximately 10 feet away, T10′s hoseline crew was blown approximately 20′ back and off the 2 ½” hoseline by the explosion. T10′s captain was backing up the nozzleman and was hit with burning debris causing serious burns on his hand and ear. T66′s captain jumped on the hoseline to stop it from whipping around. T10′s fire fighter operating the ladderpipe had seen 2 white flashes and greenish plumes just prior to explosion. When the explosion occurred he turned his head to the left causing pain and ringing in his right ear as white hot debris went all around him. Multiple hose beds and hoses on the ground were burned through. The explosion was reported to have been broadcast up and out in all directions .

The IC called for a personnel accountability report (PAR) which accounted for all personnel and indentified 2 injured fire fighters and a captain. Note: The other 4 fire fighters injuries were not made apparent until after the incident. Minutes later, the Division C chief (BC13) reported to the IC that he identified a National Fire Protection Association 704 placard above the entrance door on the C/D corner of the structure.

BC13 relayed to command the placard classifications of Health – 3, Flammability – 4, Reactivity – 2, and Special Hazards – OXIDIZER. The command team discussed the current fire department policy of using copious amounts of water on combustible metals and decided to alter the tactical plan based on information learned through the 704 placard and the fire conditions. The IC called for aerial ladderpipe personnel to move from the tip of the aerial to the aerial turntable. Note: When the decision is made to go defensive, ladderpipe personnel should be removed from the tip of the aerial to minimize any risk associated with being at an elevated height, such as explosions or falling. On Division C, two monitors and a 2 ½” hoseline were directed on the office area of the structure.

Recommendations

Recommendation #1: Fire departments should ensure that pre-incident plans are updated and available to responding fire crews.

Discussion: NFPA 1620 Standard for Pre-Incident Planning, states “The purpose of this document shall be to develop pre-incident plans to assist responding personnel in effectively managing emergencies for the protection of occupants, responding personnel, property, and the environment.” A pre-incident plan identifies deviations from normal operations and can be complex and formal, or simply a notation about a particular problem such as the presence of flammable liquids, explosive hazards, modifications to structural building components, or structural damage from a previous fire.

Building characteristics including type (or more importantly risk) of construction, materials used, occupancy, fuel load, roof and floor design, and unusual or distinguishing characteristics should be recorded, shared with other departments who provide mutual aid, and if possible, entered into the dispatcher’s computer so that the information is readily available if an incident is reported at the noted address.

Since many fire departments have thousands to hundreds of thousands of structures within their jurisdiction, it is a challenge to establish an effective preplanning system that addresses all structures and hazards. Priority should be given to those locations having elevated or unusual fire hazards and life safety considerations.

Written SOGs enable individual fire department members an opportunity to read and maintain a level of assumed understanding of operational procedures. Conversely, fire departments can suffer when there is an absence of well developed SOGs. The NIOSH Alert: “Preventing Injuries and Deaths of Fire Fighters” identifies the need to establish and follow fire fighting policies and procedures. Guidelines and procedures should be developed, fully implemented and enforced to be effective. Periodic refresher training should also be provided to ensure fire fighters know and understand departmental guidelines and procedures.

One tool for fire departments to use in assessing their risks for structures within their jurisdictions is the mnemonic, BECOME SAFE:

  • Building
  • Evaluation
  • Construction/occupancy
  • Operational hazards
  • Manage time and elements
  • Engagement
  • Situational awareness
  • Assessment and risk analysis
  • Fire behavior and effects
  • Evaluate and execute 7

A pre-planning process should integrate the BECOME SAFE concepts and include updated information from the annually submitted business plans and any other pertinent fire safety information needs to be developed by involving fire department personnel, dispatch center personnel, and building and fire code officials. NFPA 1, Fire Code, Annex Q, Fire Fighter Safety Building Marking System, makes direct reference to potential resolution towards identifying structures and contents.

It contains a standard symbol that integrates information about building construction features, content hazards, life safety systems and NFPA 704 placards into one placard. High hazard and life safety considerations for the storage, handling, and manufacturing of chemicals should be indicators to prioritize processing of the information and expediting it to the CAD system.

Current and correct information is needed to adequately address risk management issues and to comply with NFPA 1500, Standard on Fire Department Occupational Safety and Health Program, Annex A, Section 8, that addresses guidelines for the IC to consider when evaluating risk versus gain.

In this incident, the construction features of the occupancy, such as the bowstring trusses, presence of combustible metals, and access restrictions, would have been critical information to the fire department for fighting a fire at this location. A more complete pre-planning process and/or business plan updating process, involving fire department personnel, dispatch center personnel, and building code officials could have noted this information which may have aided the IC in developing a safer and more effective offensive or defensive strategy. In order to facilitate open communication, fire department personnel, dispatch center personnel, and building and fire code officials should develop a process to effectively update building information and to share this information in a timely manner. The relay of this information could be used to facilitate dynamic risk management and enhanced command and control. (Note: The fire department did a business survey following this incident and found 68 business sites that had combustible metals.)

Recommendation #2: Fire departments should ensure that fire fighters are rigorously trained in combustible metal fire recognition and tactics.

Discussion: Fire departments often respond to complex or unique hazards which require specialized/advanced knowledge and/or training in dealing with that hazard. Combustible metal fires present unique and dangerous hazards to fire fighters which are not commonly encountered in conventional structure fire fighting operations. The temperatures encountered in a combustible metal fire far exceed those of a structure fire.A block wall near the first explosion had an appearance of brown and black glass, suggesting that temperatures exceeded 3000 degrees F

The National Fire Protection Association (NFPA) 484, Standard for Combustible Metals, states that it is extremely important to conduct a good size-up by identifying the combustible metals involved, the physical state of the metals (e.g., shavings, chips, fine dust, etc.), the location relative to other combustible materials, and the quantity of the product involved. NFPA 484, A.13.3.3.10.3, states that the application of a wet extinguishing agent (particularly water hose streams) accelerates a combustible metal fire and could result in an explosion.

This is due to the water reacting with the combustible metal and giving off highly flammable hydrogen gas and oxygen. This conversion of water into hydrogen has a heat value (British Thermal Units per pound (Btu/lb)) of about 2.8 times that of gasoline, assuming 100 percent conversion of the hydrogen in the water. This equates to flowing 42.8 gallons per minute (gpm) of gasoline on the fire for every 100 gpm of water. NFPA 484, A.13.3.3.5, states that the following agents shall not be used as extinguishing agents on a combustible metal fire because of adverse reactions or ineffectiveness: water, foams, halon, carbon dioxide, nitrogen (except on iron, steel, and alkali metals, excluding lithium), and halon replacement agents.

Thus, in lieu of using a wet extinguishing agent, primarily water, it is recommended that a bulk dry extinguishing agent compatible with the product involved, such as dry sand, dry soda ash, or dry sodium chloride, be used. In most cases for large fires beyond the incipient stage, the application of a dry agent is not feasible. In these cases the best approach is to isolate the material as much as possible, protect exposures, and allow the fire to burn out naturally. Thorough training is a must to properly identify and handle these unique fires. Businesses that manufacture, use or store combustible metals, and fire departments with combustible metals in their jurisdiction, should review Chapter 13 of the National Fire Protection Association (NFPA) 484: Standard on Combustible Metals.12

Combustible metal fire training should only occur in the classroom since combustible metals are not a practical substance to use for live exercises. The excessive temperatures and the unstable nature of combustible metals when burning would put fire fighters in an unnecessary and dangerous situation, if used in live exercises.

In this incident, several fire fighters noticed the unusually bright white hot fire, white sparks, bluish green hues of the fire, and white smoke but did not recognize that this could be indicative of burning combustible metals. The fire department did not suspect that combustible metals were present until after the first explosion and the discovery of the placard indicating oxidizers were in the structure. Once identified, command directed water away from areas of suspected burning combustible metals. Later in the incident, a few concentrated areas remained burning, and copious amounts of water were directed on these areas to extinguish them. This caused a second explosion, in which no one was hurt. The titanium that was involved in the second explosion had developed a protective crust during the fire which was over 2 feet thick and contributed to the shaped charge effect when the molten metal under the protective crust came in contact with the water being applied by the ladderpipes and exploded. The development of the protective crust is a normal occurrence in combustible metal fires which actually limits open burning of the combustible metal and will result in control and extinguishment of the fire, if no actions are taken which disturb the protective crust.

In June, an incident had occurred diagonally across the street at different structure, owned by the same company, where the fire department had a combustible metal fire and was informed by employees not to use water. The fire department updated their training bulletin addressing tactics for combustible metals and removed the use of copious amounts of water.

Recommendation #3: Fire departments should ensure that policies are updated for the proper handling of fires involving combustible metals.

Discussion: The fire department had an outdated policy on the handling of combustible metal fires which primarily called for copious amounts of water to be put on a metal fire. The policy had been based on a training scenario in which burning magnesium Volkswagen engine blocks, when hit with water, would spark, but the water cooled the large mass of magnesium enough to put the fire out. Numerous fire departments across the country remember this training scenario and have not kept up with the increasing and varied uses of combustible metals in everyday products. Manufacturing and recycling facilities for these combustible metal products have been on the rise. This poses a new and different hazard for fire fighters. Combustible metals in smaller pieces and particle sizes burn at much higher temperatures, 5000 degrees F for magnesium to 8500 degrees F for zirconium, and present an explosion hazard when water comes into contact with these burning metals. When applied to burning combustible metals, water and carbon dioxide will disassociate into their base chemical elements. For example, water disassociates into hydrogen and oxygen. The added fuel and oxygen increases burning and causes extreme reactions, such as explosions. An example standard operating procedure (SOP) for the proper handling of combustible metal fires that reflects modern day hazards is provided in

Recommendation #4: Fire departments should ensure that first arriving personnel and fire officers look for occupancy hazard placards on commercial structures during size-up.

Discussion: NFPA 704, Identification of the Hazards of Materials for Emergency Response, states that all buildings or areas storing, using, or handling hazardous materials should be marked by use of a standardized placard system. The placard system identifies hazard categories for health, flammability, reactivity and special hazards, including water reactivity and oxidizers.

When conducting a size-up at commercial structures, fire officers should look for such placards. Placard locations should be located at or near entrances and unobstructed by landscaping, fencing, etc.

In this incident, placards existed at the A and C/D corner of the structure. However, they were not identified until after the explosion. The late night hour, poor lighting, angled corners of structure, and fire attack from doorways other than the front entrance may have contributed to first arriving personnel and fire officers not seeing and acting upon the information on the placard.

Recommendation #5: Fire departments should ensure that all fire fighters communicate fireground observations to incident command.

Discussion: National Fire Protection Association (NFPA) 1561, Standard on Emergency Services Incident Management System, Section 6.3 Emergency Traffic states: To enable responders to be notified of an emergency condition or situation when they are assigned to an area designated as immediately dangerous to life or health (IDLH), at least one responder on each crew or company shall be equipped with a portable radio and each responder on the crew or company shall be equipped with either a portable radio or another means of electronic communication.The U.S. Fire Administration report, Voice Radio Communications Guide for the Fire Service, provides an overview of radio communication issues involving the fire service. Effective fireground radio communication is an important tool to ensure fireground command and control as well as helping to enhance fire fighter safety and health. It is every fire fighter and company officer’s responsibility to ensure radios are properly used. Ensuring appropriate radio use involves both taking personal responsibility (to have your radio, having it on, and on the correct channel) and a crew-based responsibility to ensure that the other members of your crew (subordinates, peers, and supervisor) are doing so as well.

Receiving interior/exterior status updates is critical to the safety of fire fighters on the incident, rescue/recovery efforts, and overall control of the incident. The decision to commit interior fire fighting personnel or establishing a collapse/hazard zone for exterior fire fighting personnel should be made on a case-by-case basis with proper risk-benefit decisions being made by the incident commander.

The fireground is very dynamic, and conditions can either improve or deteriorate based on fire suppression activities, and available resources, and most importantly assessments/size-ups of the incident are necessary to detect a change on the fireground.

In this incident, several fire fighters noticed the unusually bright white hot fire, white sparks, bluish green hues of the fire, and white smoke (all potential signs of combustible metal involvement), but did not communicate it to command.

Recommendation #6: Fire departments should ensure that fire fighters wear all personal protective equipment when operating in an immediately dangerous to life and health environment.

Discussion: NFPA 1500 Standard on Fire Department Occupational Safety and Health Program states, “the fire department shall provide each member with protective clothing and protective equipment that is designed to provide protection from the hazards to which the member is likely to be exposed and is suitable for the tasks that the member is expected to perform…protective clothing and protective equipment shall be used whenever a member is exposed or potentially exposed to the hazards for which the protective clothing (and equipment) is provided.”

NFPA 1971 Standard on Protective Ensembles for Structural Fire Fighting and Proximity Fire Fighting has established minimum requirements for structural fire fighting protective ensembles and ensemble elements designed to provide fire fighting personnel limited protection from thermal, physical, environmental, and bloodborne pathogen hazards encountered during structural fire fighting operations.

These requirements will assist in protecting firefighters, but only if they wear the PPE as recommended by the manufacturer. The potential for injury at all incidents exists when fire fighters do not wear the full PPE ensemble, including gloves.

In this incident, numerous fire fighters did not don their facepiece and/or wear hoods or gloves. The potential for unknown toxic gases and flying debris as evidenced by the 2 explosions makes wearing full PPE critical for protecting fire fighters from immediate and chronic hazards. If gloves and hoods had been worn, the hand and ear burn injuries would have been less severe or perhaps totally eliminated.

Recommendation #7: Fire departments should ensure that an Incident Safety Officer is dispatched on first alarm of commercial structure fires.

Discussion: According to NFPA 1561 Standard on Emergency Services Incident Management System, “The incident commander shall have overall authority for management of the incident and the incident commander shall ensure that adequate safety measures are in place.” This shall include overall responsibility for the safety and health of all personnel and for other persons operating within the incident management system. While the incident commander is in overall command at the scene, certain functions must be delegated to ensure adequate scene management is accomplished.According to NFPA 1500 Standard on Fire Department Occupational Safety and Health Program, “as incidents escalate in size and complexity, the incident commander shall divide the incident into tactical-level management units and assign an incident safety officer (ISO) to assess the incident scene for hazards or potential hazards.” These standards indicate that the incident commander is in overall command at the scene, but acknowledge that oversight of all operations is difficult. On-scene fire fighter health and safety is best preserved by delegating the function of safety and health oversight to the ISO. Additionally, the incident commander relies upon fire fighters and the ISO to relay feedback on fireground conditions in order to make timely, informed decisions regarding risk versus gain and offensive-versus-defensive operations. The safety of all personnel on the fireground is directly impacted by clear, concise, and timely communications among mutual aid fire departments, sector command, the ISO, and the incident commander. NFPA 1521 Standard for Fire Department Safety Officer defines the role of the ISO at an incident scene and identifies duties such as recon of the fireground and reporting pertinent information back to the incident commander; ensuring the department’s accountability system is in place and operational; monitoring radio transmissions and identifying barriers to effective communications; and ensuring established safety zones, collapse zones, hot zones, and other designated hazard areas are communicated to all members on scene.

Larger fire departments may assign one or more full-time staff officers as incident safety officers who respond to working fires. In smaller departments, every officer should be prepared to function as the ISO when assigned by the incident commander. The presence of an incident safety officer does not diminish the responsibility of individual fire fighters and fire officers for their own safety and the safety of others. The ISO adds a higher level of attention and expertise to help the fire fighters and fire officers. The ISO must have particular expertise in analyzing safety hazards and must know the particular uses and limitations of protective equipment.

In this incident, for the size of the fire department and responsible coverage area, there is an insufficient number of incident safety officers (ISO) and/or qualified personnel (certified to NFPA 1521) to act as an ISO. The ISO should be of a rank worthy of the significant responsibility.

Recommendation #8: Fire departments should ensure that collapse/hazard zones are established on the fireground.

Discussion: During fire operations, two rules exist about structural collapse: (1) the potential for structural failure always exists during and after a fire, and (2) a collapse danger zone must be established.

A collapse zone is an area around and away from a structure in which debris might land if a structure fails. The collapse zone area should be at least 1½ times the height of the building—the height of the building plus an additional allowance for debris scatter. For example, if the wall was 20 feet high, the collapse zone would be established at least 30 feet away from the wall. In this incident, the structure was approximately 18 feet high at the top of the parapet wall, and the collapse zone extended at least 27 feet from the structure.

Fire fighters must recognize the dangers and take immediate safety precautions if factors indicate the potential for a building collapse. An external load—such as a parapet wall, steeple, overhanging porch, awning, sign, or large electrical service connections—reacting on a wall weakened by fire conditions may cause the wall to collapse. Other factors include fuel loads, building damage, renovation work, pre-existing deterioration as well as deterioration caused by the fire, support systems, and truss construction.

Whenever these contributing factors are identified, all persons operating inside the structure must be evacuated immediately and a collapse zone should be established around the perimeter. Once a collapse zone has been established, the area should be clearly marked and monitored to make certain that no fire fighters enter the danger zone. Positioning companies at the corners of the building is usually safer than a frontal attack. In this incident, a collapse zone should have been established given the age of the structure and deteriorating fire conditions.

Recommendation #9: Vendors/Training Organizations should develop and offer a training program on combustible metal fires.

Discussion: There are a limited amount of training materials/programs that exist on combustible metal fires. There have been a small number of presentations and workshops conducted at fire conferences over the years but nothing offered by outside training organizations that pertains to what the fire service needs to know. Programs should be developed to highlight the characteristics of a combustible metal fire, tactics, and strategies for handling them.

Gypsum Board Ceiling Systems, Ceiling Collapse and Firefighter Safety

No comments

In this week's issue of the National Fire Fighter's Near-Miss Reporting System's Report of the Week (ROTW) an informative focus was provided on near-miss reports related to ceiling collapse. We're posting the ROTW alert in it's entirety below and are expanding upon this discussion to include materials previously posted on Buildingsonfire.com from the posts that surrounded the LAFD LODD of Firefighter Glenn L. Allen  who was killed in the line of duty as a result of being trapped beneath rubble when the roof and ceiling collapsed during a blaze at a 12,000-square-foot  mansion in the Hollywood Hills on Feb. 17, 2011. (HERE and HERE)

Included in that reporting was expanded information on gypsum wall board ceiling systems.

Near-Miss Report of the Week

From the NMRS & ROTW;

The collapse of a ceiling is one of the more disorienting situations a firefighter can face. Sixty near-miss reports are returned when the keyword "ceiling collapse" is typed into the text box on www.firefighternearmiss.com. Each of these accounts provides lessons on the value of heightened situational awareness, correct use of PPE, rigorous training, and recognizing the effect of fire on building materials. The National Fire Fighter's Near-Miss Reporting System'ss Report of the Week (ROTW) featured report this week, 11-025, recounts one example.

"Our station was dispatched for a residential structure fire and we responded with two engines and four on-duty personnel… The near-miss happened about 30 minutes into the fire and there were two hoselines in place. One hoseline was on the second floor and one hoseline was on the first floor. Most of the fire was extinguished and overhaul was in progress. There were three members of my crew pulling ceiling to reach hot spots. The lieutenant stated to be careful because the floor above was moving when pulling down on overhead material. The firefighter and the lieutenant continued to pull down the ceiling. This is when the second floor collapsed down into the first floor and the room that we were in…"  

The overhead world of a fire scene is fraught with hazards. Many of the hazards we can dispassionately discuss at the kitchen table, but seem to overlook when we are engaged in firefighting. Electrical wiring, telecommunication cables, structural support systems and storage are all elements hidden behind the drywall. Whether you are looking up at a ceiling that covers an attic or an upper floor, shoving your hook through the drywall is usually a benign act that simply pulls down a section of sheetrock to expose the hidden area above. However, it can also be a catastrophic act that brings down an entrapment hazard that has you fighting for survival.

Once you have read the entire account of 11-025, and the related reports, consider the following: 

  1. Before ceiling pulling begins, is there an assessment of the structural stability and review of what might be behind the drywall before the first piece is removed?
  2. Do you and your crews observe best practices when pulling ceilings (i.e., starting at the doorway and working into the room, noting the location of structural members through visual notation of nails, "shadowing" or "ghosting" of studs, etc.) before pulling ceilings?
  3. Do you consider limiting the number of personnel in a room when ceilings and walls are being pulled?
  4. Who is responsible for ensuring utilities have been controlled before pulling ceilings and walls? How is utility control documented and confirmed before ceiling pulling begins?
  5. What is the likelihood that the space above the ceiling you are pulling is being used for storage? If storage is noted, can you determine what effect pulling down the ceiling will have on the structural members resisting the weight of the storage?

Overhaul activities occur during a transitional time in the firefighting process. The adrenaline and effort of the fire attack begins to fade, but there is still enough pent up energy that some members of the crews are propelled from one action to another without an assessment of conditions. The thinking officer and crew make periodic assessments, or benchmarks, to ensure the incident reality still matches the company's perception.

Gypsum Board Ceiling Systems and Firefigher Safety

 

The recent events in Los Angeles and the line of duty death of veteran LAFD Firefighter Glenn Allen who died Friday from injuries he sustained when a ceiling collapsed on him in a house fire late Wednesday night in the Hollywood Hills again gives us pause to reflect on the demands and hazards present at all fire suppression operations in buildings on fire. The past two months have borne consist reports of floor, roof, wall and ceiling collapses leading to firefighter injuries and line of duty deaths.

  • Incident event coverage from this past week HERE, HERE and HERE

The importance of maintaining heightened situational awareness, identifying and monitoring suspected or inherent building construction hazards coupled with inherent occupancy risk factors, and aligning those with strategic objectives, incident actions plans and tactical deployment operations. Building Knowledge equating to firefighter safety is still a driving principle that is formulative to all firefighting operations in buildings, occupancies and structures. Let’s take this opportunity to gain some insights into the material that compromises nearly all wall and ceiling membrane systems and assemblies in nearly all buildings, occupancies and structures; that is gypsum board components.

I’ve included a number of video clips that center on our discussion, as the videos center on the operation parameters at this extremely large (floor area/square footage) residential occupancy. Most clips have good coverage of the structure and firefighting efforts. Take a few moments to review these clips before you proceed;




Gypsum board is the generic name for a family of panel-type products consisting of a noncombustible core, primarily of gypsum, with a paper surfacing on the face, back, and long edges.

In 1888, Augustine Sackett used plaster of Paris sandwiched between several layers of paper to produce what would eventually become "Sackett Board," the original gypsum board. By the 1950s, many innovations in gypsum board technology had been developed, including the listing of many fire-resistance rated designs, rounded edges, specialized nails, curved partitions, studless partitions, sound control systems, lightweight gypsum lath, plaster, and gypsum board systems that fueled a boom period for the use of gypsum products in both the residential and commercial construction industries.

By 1955, an estimated 50 percent of new homes were built using gypsum wallboard. Lightweight gypsum board systems permitted the use of lightweight steel in steel framed buildings, which enabled the widespread growth of high-rise residential and commercial construction during the 1960s and 1970s.

Today gypsum board, along with a variety of other gypsum panel products, continues to serve as a preferred building material in both residential and commercial construction for interior walls and ceilings, exterior sheathing, fire-resistant partitions and membranes, and liner material for elevator shafts and stairwells. These properties make gypsum board well suited for building and space types requiring cost-effectiveness as well as fire resistiveness and maintainability.

Gypsum board is often called drywall, wallboard, or plasterboard and differs from products such as plywood, hardboard, and fiberboard, because of its noncombustible core. It is designed to provide a monolithic surface when joints and fastener heads are covered with a joint treatment system.

Gypsum is a mineral found in sedimentary rock formations in a crystalline form known as calcium sulfate dehydrate. One hundred pounds of gypsum rock contains approximately 21 pounds (or 10 quarts) of chemically combined water. Gypsum rock is mined or quarried and then crushed. The crushed rock is then ground into a fine powder and heated to about 350 degrees F, driving off three fourths of the chemically combined water in a process called calcining. The calcined gypsum (or hemihydrate) is then used as the base for gypsum plaster, gypsum board and other gypsum products.

To produce gypsum board, the calcined gypsum is mixed with water and additives to form a slurry which is fed between continuous layers of paper on a board machine. As the board moves down a conveyer line, the calcium sulfate recrystallizes or rehydrates, reverting to its original rock state. The paper becomes chemically and mechanically bonded to the core. The board is then cut to length and conveyed through dryers to remove any free moisture.

Gypsum manufacturers also rely increasingly on “synthetic” gypsum as an effective alternative to natural gypsum ore. Synthetic gypsum is a byproduct primarily from the desulfurization of the flue gases in fossil-fueled power plants. Gypsum board is an excellent fire resistive material. It is the most commonly used interior finish where fire resistance classifications are required. Its noncombustible core contains chemically combined water which, under high heat, is slowly released as steam, effectively retarding heat transfer. Even after complete calcination, when all the water has been released, it continues to act as a heat insulating barrier. In addition, tests conducted in accordance with ASTM E 84 show that gypsum board has a low flame spread index and smoke density index. When installed in combination with other materials it serves to effectively protect building elements from fire for prescribed time periods.

Developed through modern technology as a result of specific requirements, gypsum board is mainly used as the surface layer of interior walls and ceilings; as a base for ceramic, plastic, and metal tile; for exterior soffits; for elevator and other shaft enclosures; as area separation walls between occupancies; and to provide fire protection to structural elements. Most gypsum board is available with aluminum foil backing which provides an effective vapor retarder for exterior walls when applied with the foil surface against the framing.

Standard size gypsum boards are 4ft. wide and 8, 10, 12, or 14 ft. long. The width is compatible with the standard framing of studs or joists spaced 16 in. and 24 in. on center. Some thicknesses and types of gypsum board are also produced as a standard 54 in. width material. Other lengths and widths are available as special order materials.

  • Depending on thickness and type of gypsum board, the weight can vary from 2 – 4 lbs./ per square foot
  • A typical 4 ft. x 8 ft. sheet of 5/8-in gypsum board can weigh 96 lbs.
  • A 4ft. x 12ft. sheet can weigh upwards of 150 lbs.
  • In large span designs with attachments varying from 16 inches on center to 24 inches on center with z-strips or resilient channels attached to the structural members; these ceiling panels and assemblies can fail and collapse in a monolithic manner creating a significant safety concern to operating companies below.
  • As an example a 12ft x 12ft. monolithic assembly collapse ( single layer-gypsum board only) could have a collapse weight of 500 lbs.
  • Add the weight of compromised and attached structural members components, fixtures and insulation and the absorption of added water into the gypsum board from hose streams the combined weight of the collapse area may increase to 800-1000 lbs. Increase the size of the collapse area and the weight impacting operating companies is significant.

The various thicknesses of gypsum board available in regular, type X, improved type X and pre-decorated board are as follows:

  • ¼-in. A low cost gypsum board used as a base in a multi-layer application for improving sound control, or to cover existing walls and ceilings in remodeling.
  • 5/16-in. A gypsum board used in manufactured housing.
  • 3/8-in. A gypsum board principally applied in a double-layer system over wood framing and as a face layer in repair or remodeling.
  • ½-in. Generally used as a single-layer wall and ceiling material in residential work and in double-layer systems for greater sound and fire ratings.
  • 5/8-in. Used in quality single-layer and double-layer wall systems. The greater thickness provides additional fire resistance, higher rigidity, and better impact resistance.
  • ¾-in. Used in a similar manner to 5/8-in.
  • 1 in. Used in interior partitions, shaft walls, stairwells, chaseways, area separation walls and corridor ceilings. Manufactured only in 24 in. wide panels and usually installed as an integral part of a system.

Depending on the type and the use, gypsum board is manufactured with a tapered, square, beveled, rounded, or tongue and groove edge. Some gypsum board types may incorporate a combination of different edge types. The fire resistance of gypsum board can be described using three distinct terms: regular core, type ‘X’ core and improved type ‘X’ core.

Regular core gypsum board is made of a noncombustible core material composed mainly of gypsum. Although it does not have the specially enhanced fire-resistive properties of type ‘X’, regular core gypsum board affords a degree of natural fire resistance.

In the 1940s different gypsum board formulations were investigated to increase the naturally occurring fire resistance of regular core gypsum board. A new product was eventually introduced that clearly demonstrated “eXtra” fire resistance, hence the name “type X.” The basic components of type ‘X’ that give it a superior fire resistance are gypsum, glass fibers, and vermiculite.

In the 1960s, further modifications were made to the original successful type ‘X’ formulations of gypsum board used in some systems – particularly ceiling systems – without compromising the fire-resistive qualities. The new product demonstrates additional fire resistance over type ‘X’ core, and thus the term “improved type X” was coined. Gypsum board products make up the predominant portion of a family of materials identified as gypsum panel products. Gypsum panel products are defined as sheet materials consisting essentially of gypsum. They can be faced with paper or another material, or may be unfaced. Gypsum board, glass-faced sheathing materials with a gypsum core and unfaced gypsum-based products are all considered to be gypsum panel products. Technically, gypsum board is defined as the generic name for a family of sheet products consisting of a noncombustible core, primarily of gypsum, with a paper surfacing on the face, back, and long edges. In recent years the family of gypsum-based panel materials has grown to include panel products other than those with the familiar paper facers. A number of specialized gypsum panel products and gypsum boards have been developed for specific uses which include:

  • Gypsum Wallboard for interior walls and ceilings
  • Gypsum Ceiling Board for interior ceilings
  • Type X Gypsum Board for fire-resistance-rated building systems
  • Fiber Reinforced Gypsum Panels for interior and exterior walls, ceilings, and tile base
  • Gypsum Sheathing for exterior walls and roof systems
  • Glass Mat Gypsum Substrate for use as sheathing on exterior walls and ceilings
  • Gypsum Soffit Board for use on exterior soffits and ceilings
  • Water-Resistant Gypsum Backing Board for use as a tile base
  • Glass Mat Water-Resistant Gypsum Backing Board for use as a tile base
  • Gypsum Backing Board for use as a base for multi-ply systems
  • Gypsum Lath for use as a base for gypsum plaster
  • Gypsum Plaster Base for use as a base for veneer plaster
  • Gypsum Shaft Liner Board for shaft, stairway, and duct enclosures
  • Pre-decorated Gypsum Board for accent walls, office and movable partitions
  • Foil backed gypsum board for use as a vapor retardent

Identified by their technically correct names, gypsum board products are as follows: Gypsum Wallboard is produced primarily for use as an interior surfacing for buildings. It is the most often used commodity gypsum board and annually accounts for over 50 percent of all the gypsum board manufactured and sold in North America. Gypsum wallboard has a manila-colored face paper and is manufactured in a variety of thicknesses as both a regular- and a fire-resistant core material.

Gypsum Ceiling Board is an interior surfacing material with the same physical appearance as gypsum wallboard. Gypsum ceiling board is manufactured as a ½-inch thick material; it is designed for application on interior ceilings, primarily those intended to receive a water-based texture finish. It has a sag resistance equal to 5/8-inch thick gypsum wallboard.

Predecorated Gypsum Board has a decorative surface which does not require further treatment. The surfaces may be coated or painted, printed, textured, or have a film – such as vinyl wallcovering – applied. It is manufactured in a variety of thicknesses as both a regular- and a fire-resistant core material.

Water-resistant Gypsum Board is a gypsum board designed for use on walls primarily as a base for the application of ceramic or plastic tile. It is readily identified by its green-tinted face paper and is commonly referred to as “Greenboard.” It has a water-resistant core and a water-repellent face and back paper; it is generally installed in bath, kitchen, and laundry areas.

Gypsum Backing Board, Gypsum Coreboard, and Gypsum Shaftliner Panel are all designed to be used as base materials in multi-layer, solid and semi-solid, and shaftwall systems. Gypsum backing board is used as a base layer for other gypsum board materials in systems or as a base for dry claddings such as acoustic tile. Gypsum coreboard and gypsum shaftliner are manufactured with a type X core, using a specific edge configuration to facilitate installation into specialized stud systems and a type X core.

Exterior Gypsum Soffit Board is designed for use on the underside of eaves, canopies, carports, soffits, and other horizontal exterior surfaces that are indirectly exposed to the weather. It has water-repellent face and back paper and is more sag-resistant than regular wallboard. Exterior gypsum soffit board can be manufactured with a type X core and typically has a light brown face paper.

Gypsum Sheathing Board is used as a backing under exterior siding or cladding. It has a water-repellent face and back paper and can be manufactured with a water-resistant core. Depending on the thickness of the board, gypsum sheathing board is manufactured with either a square or a tongue-and-groove edge and a fire-resistive core. It generally has a brown or light black face paper.

Gypsum Base for Veneer Plaster has a distinctive blue-tinted face paper that is treated to facilitate the adhesion of thin coats of hard, high strength gypsum veneer plaster. It is produced in sheets that are the same width as gypsum wallboard and can be manufactured with a fire-resistive core. Application of Gypsum Board

A wide variety of gypsum board application methods are available to meet virtually any need in building design and construction. Gypsum board is applied in either single-layer or multi-layer systems to achieve specific fire or sound ratings. Gypsum board is applied over wood or steel framing or furring. It is also applied to masonry or concrete surfaces, either laminated directly or attached to wood furring strips or steel furring channels. Gypsum board ceilings can be directly attached to joists or trusses or attached to furring or grid systems suspended below structural members. Gypsum board is generally attached to the framing with nails, screws, or staples. Although nails are commonly used in wood frame construction, screws are often preferred because they are applied with automatic screw guns, have excellent holding power, and reduce the possibility of nail pops. A combination of nails and screws may also be used, with nails along edges and screws in the field. Staples are used because they are economical and can be quickly applied with staple guns; however, the use of staples should be limited to the base-layer in multi-layer systems or to gypsum sheathing on wood framing. Gypsum board wall and ceiling surfaces are typically decorated with paint, texture, wallpaper, tile, or paneling. When pre-decorated gypsum board is used, joints are generally covered with matching molding or battens; no additional finishing or decoration is necessary. Single-Layer Application

  • Single-layer gypsum board applications are the most common in light commercial and in residential construction.
  • These systems rely on one layer of gypsum board attached to framing or furring.
  • Although single-layer gypsum board systems are generally adequate to meet most minimum requirements for fire resistance and sound control, multi-layer systems are preferred for higher quality construction and to upgrade beyond the "bare minimums" of many code requirements.

Multi-Layer Application

  • Multi-layer systems have two or more layers of gypsum board and are used to meet higher sound and fire resistance requirements or to enhance these comfort and safety qualities beyond minimum code requirements.
  • They also provide better surface quality because face layers can often be laminated over base layers eliminating many or all of the fasteners in the face layer. In addition, face-layer joints are stronger by virtue of the continuous backing provided by the base layers.
  • Nail pops and ridging are less frequent and imperfectly aligned framing has less effect on the quality of the finished surface.

GYPSUM BOARD TYPICAL MECHANICAL AND PHYSICAL PROPERTIES (GA-235-10) A common misconception is that there are just two basic types of drywall—regular and type X—and beyond this difference, drywall products from various manufacturers are about the same. However, laboratory fire tests by United States Gypsum Company and various independent testing organizations provide strong evidence that there are significant fire-performance differences between drywall products from various manufacturers. It is well known in the construction industry that the single most important characteristic of gypsum drywall is its fire resistance. This is provided by the principal raw material used in its manufacture, CaSO4- 2H2O (gypsum). As the chemical formula shows, gypsum contains chemically combined water (about 50% by volume). When gypsum drywall panels are exposed to fire, the heat converts a portion of the combined water to steam. The heat energy that converts water to steam is thus used up, keeping the opposite side of the gypsum panel cool as long as there is water left in the gypsum, or until the gypsum panel is breached.

  • In the case of regular gypsum panels, as the water is driven off by heat, the reduction in volume within the gypsum causes large cracks to form, eventually causing the panel to fail.
  • In a special fire test designed to demonstrate the relative performance of different types of gypsum cores (described later in this section), it was shown that in a fire with a temperature of 1,850ºF, a 5/8" thickness of regular-core gypsum panels would fail in this manner in 10 to 15 minutes.
  • Type X gypsum panels, such as Sheetrock brand Firecode gypsum panels, have glass fibers mixed with the gypsum to reinforce the core of the panels.
  • These fibers have the effect of reducing the extent of and size of the cracks that form as the water is driven off, thereby extending the length of time the gypsum panel can resist the heat without failure.
  • Fire test results indicate that the same thickness of the type X gypsum drywall exposed to the same temperature (1,850ºF) will last 45 to 60 minutes.

USG has developed a third-generation gypsum drywall product called Sheetrock brand Firecode C gypsum panels that provides even greater resistance to the heat of fire. The core of Firecode C contains more glass fibers than type X—but also a shrinkage-compensating additive, a form of vermiculite that expands in the presence of heat at about the same rate as the gypsum in the core shrinks (from loss of water). Thus the core becomes highly stable in the presence of fire and remains intact even after the combined water is driven off. Tests have shown that this third-generation product resisted the fire for more than two hours, as compared to 45 to 60 minutes for the type X, and 10 to 15minutes for the regular panel under the same test conditions.

In a future posting we’ll discuss the issues facing the fire service related to the newest generation of impact resistant gypsum board that will restrict or preclude entirely our ability to breach walls in residential or commercial occupancies.

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

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

Contributing Factors

 

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

Key Recommendations

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

NIOSH Recommendations

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

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

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

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

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

The Fire Deparment Connection

 

There are some discussions emanating and emerging regarding the Medical Center Fire in Asheville, NC that claimed the life of a highly regarded Captain and injured numerous firefighters. Emerging reports are discussing water supply, standpipe operability and integrity and deployment delays affecting fire behavior, growth, intensive and operational risks during the time in which water was attempting to be delivered to hand lines extended on the fire floor of the Medical Center.

See coverage HERE on CommandSafety.com and HERE at the Asheville Citizens-Times.com today. Direct link HERE

The following links have been compiled that provide a variety of insights and perspectives on operations conducted with standpipe systems.

Two 1.5-inch attack lines off a gated wye (poor standpipe valve positioning - the second line probably would kink when charged). Technically, a 2.5-inch to 2.5-inch gated wye with reducers is better if a high-volume (2.5-inch) line is suddenly needed. Copyright © 2011 Massey Enterprises, Inc.

Large Loss Building Fires Report

No comments

Photo Dave Bullock http://eecue.com/

 

The Federal Emergency Management Agency’s (FEMA) United States Fire Administration (USFA) have recently issued a special report examining the characteristics and causes of Large Loss Building Fires (PDF, 834 Kb). 

The report, developed by USFA’s National Fire Data Center, is based on 2007 to 2009 data from the National Fire Incident Reporting System (NFIRS).

  • From 2007 to 2009, an estimated 900 large loss building fires were reported by U.S. fire departments annually. 
  • These fires caused an estimated 35 deaths, 100 injuries, and $2.8 billion dollars in property damage. 
  • In this report, large loss building fires are defined as fires that resulted in a total dollar loss of $1 million or more.

According to the report:

  • Forty-eight percent of large loss fires occur in residential buildings.
  • Exposures are the leading cause of large loss building fires at 22 percent, followed by electrical malfunctions (12 percent), other unintentional, careless actions (11 percent), and intentional (9 percent).
  • A peak in large loss building fires is seen between the hours of 1 a.m. and 4 a.m.
  • Attics are the primary origin of all large loss building fires, along with cooking areas or kitchens.

Large Loss Building Fires (PDF, 834 Kb) is part of the USFA’s  Topical Fire Report Series. 

Topical reports explore facets of the U.S. fire problem as depicted through data collected in NFIRS.  Each topical report briefly addresses the nature of the specific fire or fire-related topic, highlights important findings from the data, and may suggest other resources to consider for further information.

Also included are recent examples of fire incidents that demonstrate some of the issues addressed in the report or that put the report topic in context.

Examples

The following are some recent examples of large loss fires reported by the media:

  • October 2010: A fire in a Franklin, TN, home resulted in $2.5 million worth of damage. The cause of the fire is still unknown, but the fire began in a patio fireplace. The family of four present in the house at the time of the fire was able to escape safely. Four firefighters were injured while fighting the fire; two of them were treated at the scene and two were sent to the hospital for minor injuries.
  • June 2010: A Palo Alto, CA, two-alarm house fire caused between $1 and $2 million worth of damage. The family of four living in the house was awoken by their son when he heard the smoke alarm. The fire is believed to have been started by an unattended candle or cigarette the son left in a second-story room. The fire was brought under control in about 45 minutes and no deaths or injuries were reported.
  • June 2010: A fire that started in a Carmel, IN, shopping mall is believed to have been caused by lightning. Investigators have determined that the fire started in a restaurant located at the north end of the mall. There were no deaths or injuries as a result of the fire, but investigators estimate that the fire caused over $5 million worth of damage.
  • May 2009: A fire that started in a Gallery Furniture storage warehouse located in Houston, TX, resulted in at least $15 million worth of damage. Investigators have determined that the fire was caused by arson. Thirty to 40 employees were present when the fire broke out. The fire was determined to have been started in an area only accessible to employees. There were no injuries or deaths as a result of the fire.

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

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

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

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

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

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

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

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

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

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

Self-Survival Procedures

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

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

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

 

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

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

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

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

Other Training and Drill Opportunties

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

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

    • NIOSH Alert: Preventing Deaths and Injuries of Fire Fighters using Risk Management Principles at Structure Fires
      • Fire fighters are often killed or injured when fighting fires in abandoned, vacant, and unoccupied structures.
      • These structures pose additional and sometimes unique risks due to the potential for fire fighters to encounter unexpected and unsafe building conditions such as dilapidation, decay, damage from previous fires and vandals, and other factors such as uncertain occupancy status. Risk management principles must be applied at all structure fires to ensure the appropriate strategy and tactics are used based on the fireground conditions encountered.

      • NIOSH Report; Preventing Deaths and Injuries of Fire Fighters Working Above Fire Damaged Floors
        • Fire fighters are at risk of falling through fire-damaged floors. Fire burning underneath floors can significantly degrade the floor system with little indication to fire fighters working above.
        • Floors can fail within minutes of fire exposure, and new construction technology such as engineered wood floor joists may fail sooner than traditional construction methods.
        • NIOSH recommends that fire fighters use extreme caution when entering any structure that may have fire burning beneath the floor.

Roof and floor truss system collapses in buildings that are on fire cannot be predicted and may occur without warning.
          • NIOSH recommends that fire departments review their occupational safety programs and standard operating procedures to ensure they include safe work practices in and around structures that contain trusses. Building owners should follow proper building codes and consider posting building construction information outside a building to advise fire fighters of the conditions they may encounter.

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

3 comments

Fire Service Tradition and The Brotherhood

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

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

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

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

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

History Repeating Events-Integrate into your Training

 

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

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

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

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

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

What are we Learning? What are we Applying?

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

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

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

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

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

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

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

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

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

Fire/EMS Safety, Health and Survival Week 2011: Day Five: Near-Misses, Maydays and Floor Collapses

1 comment

Do you know what's underneath you as you're making entry?

During the last quarter of 2010 and leading well into the second quarter of 2011 there has been a significant emerging trend developing in basement fires, compromised floor systems and assemblies leading to collapse and numerous near-miss events, close calls and unfortunatly, line of duty deaths during fire operations.

If you’ve been paying attention to the various news and on the job reports these past number of months, you may have noticed the increasing numbers of emerging trend evident in near miss, close-calls resulting in maydays, RIT deployments and self-rescue resulting from floor compromise and floor collapse. The double line of duty deaths of two San Francisco (CA) Fire fighers while operating in a Terraced (Hillside construction) residential occupancy while operating below the base level diaphragm (upper street level access). (HERE)

In December 2010,  I was doing some research and posting links related to the first one or two events on Buildingsonfire on Facebook, HERE, it became evident at the time that there was an immediate opportunity to get some learning’s and insights out. If you have a chance head over to Facebook and link into Buildingsonfire and check out the incident links posted as well as some immediate report links. (Demember 2010 time frame)

In a coincidential posting on July 28, 2010, I posted on CommandSafety.com an interesting incident that I came across while preparing for a new post related to a near-miss event that occured in which a Camp Taylor (KY) firefighter survived a floor collapse that momentarily trapped him proximal to the seat of a working basement fire. Camp Taylor (FD) Captain Michael Long sustained second and third degree leg burns after falling through the floor of the burning home and subsequently being rescue by other fire department personnel after calling a mayday.

This event has all the ingrediants the the 2011 Safety Week focus on Surviving the Fire Ground and managing the Mayday. Little did I know that later, in February 2011, while participating in the National FireFighter Near-Miss Reporting System Stakeholders meeting in California, would I have the chance to hear Captain Long’s story first hand, and then also have the opportunity to have him as a guest, sharing his story live on the Taking it to the Streets Radio program in February. (HERE)

Camp Taylor (FD) Captain Michael Long’s near-miss and story of survival resonates with this year’s theme of  Surviving the Fire Ground- Firefighter, Fire Officer and Command Preparedness and Managing the Mayday and provides an opportunity to focus on the event in this, Day Five of the 2011 Fire/EMS Safety, Health and Surival Week activities. The details of Captain Long’s story can be found on the National FireFighter Near Miss Reporting System web site (HERE) as well as in the June 2011 issue of Fire Engineering Magazine titled, Floor Collapse: A Survivors Story. Let me state upfront also the Captain Michael Long will be presenting the accounts of his near miss event and the lessons-learned at IAFC Fire-Rescue International Conference in Atlanta in August (HERE).

 On July 25, 2010, Captain Michael Long of the Camp Taylor (Ky.) Fire Protection District fell through the floor of a house during a four-alarm fire and suffered severe burn injuries. On Aug. 30, 2010, Capt. Long submitted a near-miss report based on this event. The National Fire Fighter Near-Miss Reporting System is an anonymous and confidential reporting system; however, Capt. Long wanted to have his name associated with this report so that others would understand the value of sharing near-miss events. What follows is an excerpt from his report and excerpts from a recent phone interview. To read his full report, including an extensive lessons learned section, search by report number for report #10-1072 on the Search Reports page of www.firefighternearmiss.com.

  

Near Miss Report Event #2010-1072

  

 “I made sure my crew was ready to enter, sounded the floor for stability and then crossedover the threshold, entering the structure. When I was approximately 5 feet inside the structure, I felt the floor start to give way. I turned toward the front door to try to bail out, and at the same time yelled at others to get out, when the floor system collapsed. This was no ordinary collapse. More than two-thirds of the first floor collapsed simultaneously. The living room, dining room, kitchen, bathroom and foyer all fell at once. “When the collapse happened, I was the only one who fell into the basement, right into the heart of the fire. All I could see around me were flames.

I could not see the hole that I had fallen through. I could not see my fellow firefighters above me. All I could see was fire. I began to try to find something to use to climb back up with. Since I did not know what type of collapse had occurred, I just started clawing away at anything as I was trying to climb. During this time, my legs were burning.

Fire was burning up between my boots and my bunker pants. The pain was intense. My deputy chief was trying to put a line on me for protection, but the fire was extremely intense. He was lying on the porch with fire shooting out over his head. He stated he could occasionally see the top of my helmet and the reflective stripes on my coat sleeves.

By a bit of luck, a roof ladder was laying in the front yard that had just been taken off the roof after the completion of a ventilation operation.

My deputy chief directed the crew to put the ladder into the hole for my escape. “By this time, I was burned on my legs and struggling with exhaustion and the intense heat. I was screaming both from pain and due to fear. I could hear screaming coming from above, butwas unable to make out the majority of it. I finally heard the word “ladder” and then felt something across my back. Once they got the ladder into the basement, I had to get around to it. I still could not see anything but fire, so this was all by feel. As I started up the ladder, I got two rungs up, reached for the third rung, and lost my grip and fell back into the basement landing on my back. I was so exhausted that I started making my peace with God that this was where I was going to die.

Captain Long

Incident Lessons Learned from Captain Long:

  • Train as if it is real. Train, train, train, and then train some more. Take advantage of every opportunity to train. The better we are trained, the less our chance of injury. The training must be physically and mentally. Crews must focus on more hands-on scenario-based training that allows for problem solving. If crews are taught that the outcome to every scenario is static, they are not being encouraged to think. Every run is different; no single solution applies to every situation. Adaptations or decisions that are not in step with changing conditions can actually be disadvantageous. We must make the right decisions based on the correct interpretation of the environment and blend those observations with our knowledge, skills, and abilities to map a course of action that will lead us to a successful outcome. Read reality and come up with the best possible plan. In my situation, quick thinking and adapting to the problem that presented itself saved my life.
  • Mutual-aid training is a must. We must train more with our neighboring departments to improve operations. It is occasionally difficult to work in situations where you do not really know with whom you will be working or where the command structure and tactics differ from those of your department. We all learn from the same book; however, the interpretations and tactics differ from person to person and department to department. I am not saying anyone is right or wrong in the way they do things—we all just need to do a better job of understanding that there is more than one way to get the job done.
    We cannot know exactly how everyone on an emergency scene will perform because each person has a different interpretation of his surroundings and role in the system. Standard operating guidelines (SOGs) can assist in this area, but SOGs rely on perceptions and interpretations by individuals to be implemented as intended. Accidents often happen because everyone has a unique perspective on the environment, and each makes different decisions based on their perception.
    We must perceive the environment correctly to ensure we make the right move. If these actions are not communicated and coordinated in the intricate system that is the fireground, accidents will be the inevitable and regrettable results. Training and frequent reviewing of SOGs are vital to our safety.
  • Risk assessment. Sounding the floor prior to entry is not always a good indicator of the floor’s stability. Less than two minutes before I made entry, there were three other firefighters, at least the same weight as I, in the same area where the collapse occurred. Everything changed in a very short time. There was no warning. Adkins told me at the hospital that all he heard was a “whoosh” sound when the floor collapsed. Then I disappeared. Within two minutes, the floor assembly went from being able to sustain a live load of at least 900 pounds in that area (accounting for gear, equipment, SCBA, and so on) to collapsing with about a 300-pound load, and I was close to a load-bearing wall. A good way to evaluate risk vs. gain is to get the most accurate report on burn time as possible to help determine structural integrity.
  • Rapid intervention. RIT is a critical fireground benchmark and is very important for safety, but it would have been ineffective in this situation. Had my crew not reacted the way they did immediately, I would not have been able to last long enough to wait for the RIT. In the time it would have taken for the RIT to gear up, come up with a plan, and enter, I would have died. The stars aligned in my favor that night. The person calling the Mayday or a nearby crew often mitigates personnel emergencies. My crew was able to act decisively at the correct time, and I am alive because of it. It is important to remember that a large percentage of Maydays are mitigated by the crew to which the lost firefighter is assigned or a nearby crew. RIT deployments account for a small number of rescues; we must always be alert and ready for the “incident within the incident.”
  • Manage your emotional response. From a personal standpoint, you must rely on your training and try not to panic. Know your equipment and procedures well. I did panic, but I was still able to keep myself together enough to know not to leave the area since I had been told that the stairs had burned away. Keeping my SCBA on, resisting the emotional reaction to remove my mask because of claustrophobia, was a huge factor in my survival. If I had tried to find another way out, my crew could not have gotten to me with the ladder. Had I removed my mask, the story would have ended quite differently. When I teach, I try to train as if it is the real thing. Never take a run for granted. Always expect the worst; you will be better prepared to deal with the unexpected.
    If we continually study accident reports and learn from them, the likelihood of being surprised will be diminished. Peter Leschak writes in Ghosts of the Fireground: ”In fire and other emergency operations, you must not only tolerate uncertainty; you must savor it, or you won’t last long. The most efficient preparation is a general mental, physical, and professional readiness nurtured over years of training and experience. You live to live. Preparing is itself an activity, and action is preparation.”
  • Talk about it. Critical incident stress debriefing (CISD) is important for ensuring that personnel from all departments on scene are taken care of emotionally. CISD needs to extend beyond just one or two briefings. Personnel involved in a highly emotional event must be given the opportunity to speak to a trained CISD team member early and be given as much time as is needed to work through their issue. Some firefighters have a macho attitude and try to deal with their emotions on their own, or maybe they don’t deal with them at all. Others self-medicate with alcohol or, worse, these difficult emotional events are allowed to fester with no relief. People should be accepting of those who deal with issues up front and tell their stories. Telling these stories makes us better and helps to keep us safe. This reduces the possibility of “snapping” because you have too much pent-up emotion.
    My fellow firefighters are still affected by this event, even those who were not there. Department personnel must be open-minded and receptive to the fact that emotional events will affect your performance and your personal life and that it is acceptable to be open and deal with them. When difficult emotional situations present themselves, members should attempt to deal with them as soon as possible.
  • Know what is possible and what is not. Know the experience level of your crew. Going into a bad situation with a crew that may not have exposure to a lot of different situations or that you aren’t that familiar with could make operations more difficult. I had everything from a 30-year veteran to a one-year recruit, so the experience level was all across the board. I knew that the situation we were going into was getting worse and required quick action, so I took the lead to ensure that the operation would be completed as quickly as possible. I knew my deputy chief would be watching us to ensure things were proceeding safely. I knew my crew could get the job done; however, this was an operation that is not often practiced and I wanted to make sure it was done correctly. I will not send my crew into an area that I am not comfortable going into. The more you train and the more people you can train with, the better you will understand your capabilities.

    This seems like a good time to have a ten minute drill on these events as Operating Experience (OE) on floor systems and operational safety, calling or commanding the mayday.

     Or take some time to visit the The IAFF Fire Ground Survival Program (FGS)site which has the most comprehensive survival-skills and mayday-prevention program currently available and is open to all members of the fire service. Incorporating federal regulations, proven incident-management best practices and survival techniques from leaders in the field, and real case studies from experienced fire fighters, FGS aims to educate all fire fighters to be prepared if the unfortunate happens.  (Day One: Are you ready, HERE)

    Self-Survival Procedures

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

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

    Disentanglement Maneuvers

    Fires inside an enclosed structure create a mess for fire fighters operating on the floor. Fire fighters often encounter debris that has fallen off shelves, and ceiling and wall fixtures that have burned and are left hanging to the floor. These hazards, coupled with the mess a fire fighter creates when searching for victims in smoky environments, can create egress problems for a fire fighter.

    As fire burns draperies, blinds, lighting fixtures, computer wiring, and HVAC ducting, the possibility of encountering an entanglement hazard increases. The overhead ducting of the HVAC system contains wires that give the ducting its stability.

    If a fire breaches the ceiling and burns the ducting, the wires within the ducting fall to the floor. These wires can cause a dangerous entanglement hazard to fire fighters operating on the floor. Fire fighters must anticipate these hazards and have a plan to follow when egress is cut off.

    Fire Fighter Expectations of Command

    FGS Online Program Chapter 5
    A discussion of what command must communicate to the distressed fire fighter, dispatch, the RIT group supervisor and all others assigned to the incident to assure a successful rescue.

    Here are Some Mission Critical Reference Links for Operational Insights and Operating Experience (OE) to support Your Training and Operational Needs not only this week, but through the entire year.

     

    Here are some Safety Considerations related to Residential Occupancies (non-inclusive) for Operations at Basement Fires that will support fireground operational safety:

    • Conduct a thorough fire size-up and communicate the findings to all personnel on-scene before entering the building.
    • Conduct an assessment of the Building Profile ( building construction type, structural assembly systems and features and age) and assesss fire behavior and intensity levels.
    • Ensure an adequte Risk Assessement is conducted and that Risk versus Gain is determined
    • Maintain situational awareness throughout the tactical deployment of crews within the interior of the structure
    • Conduct a 360 degree perimeter assesement when feasible to determine access and egress points, fire location and travel and other mission critical operational perameters.
    • Incident commanders and company officers should be trained and experienced in structure fire size up to avoid putting fire fighters at unneeded risk of working above fire-damaged floors.
    • Do not enter a structure, room, or area when fire is suspected to be directly beneath the floor or area where fire fighters would be operating, or if the location of the fire is unknown.
    • Never assume structural safety of any floor (regardless of the construction) having a significant fire under it.
    • Conduct pre-incident planning inspections during the construction phase to identify the type of floor construction.
    • If pre-planning is not conducted, assume residential construction and small commercial buildings built since the early 1990s may contain engineered wood I-joists.
    • Report construction deficiencies noted during preplanning to local building code officials. For example, engineered wood floor joists should only be modified per manufacturer specifications—usually limited to cutting to length and removing pre–cut knockouts for utility access. Report damaged or cut chords or webs to building officials.
    • Develop, enforce, and follow standard operating procedures (SOPs) on how to size up and combat fires safely in buildings of all construction types. Rapid intervention teams (RIT) should include a portable ladder with their RIT equipment when deployed at basement fires.
    • Ensure Time Compression is considered: Ensure Command has the ability to monitor progress or elapsed incident time and adjusts strategic and tactical plans accordingly and in a time effective manner. 
    • Provide training on identifying signs of weakened floor systems (soft or spongy feel, heat transmitted through floor, downward bowing, etc.).
    • Make fire fighters aware that all floor types can fail with little or no warning.
    • Use a thermal imaging camera to help locate fires burning below or within floor systems, but recognize that the camera cannot be relied upon to assess the strength or safety of the floor. (Refer to the recent UL Test Data and Operational Safety Considerations ”Structural Stability of Engineered Lumber in Fire Conditions” available at http://www.uluniversity.us/ )
    • Fire fighters should be trained on the use of thermal imaging cameras, including limitations and difficulties in detecting fire burning below floor systems. (See reference to UL above)
    • Immediately evacuate and, if possible, use alternate exit routes when floor systems directly beneath the floor where fire fighters would be operating are weakened by fire.
    • Use defensive overhaul procedures after fire extinguishment in structures containing fire-damaged floor systems of all types.
    • Consider becoming active in the building code process and influence requirements for fire resistance of floor and ceiling systems to further fire fighter safety and health.
    • Ensure RIT personnel area staged and have complete a site assessment of the building and occupany upon thier arrival and set-up
    • Ensure that a rapid intervention team (RIT) is on the scene as part of the first alarm and in position to provide immediate assistance prior to crews entering a hazardous environment

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

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

    New Rules of Engagement

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

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

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

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

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

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

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

     

    Original IAFC 2001 ROE

     

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

     

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

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

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

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

    These included the;

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

     Three Section members also participated in the IAFF project.

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

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

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

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

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

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

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

    The project team was lead by Chief Gary Morris,

    • contains the lesson plans for the Incident Commanders Rules of Engagement for Firefighter Safety.

     Section Eight

    • serves as appendixes and contains full investigation reports of several significant firefighter fatality incidents.

     The Need for Rules of Engagement

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

     

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

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

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

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

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

     

    Operational Excellence and the ROE

     

    The NEW Rules of Engagement

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

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

    No firefighter’s life is a building that eventually will be rebuilt. Keep all members safe so “Everyone Goes Home”!

    • You Are Required to Abandon Your Position and Retreat Before Deteriorating Conditions Can Harm You.
    • Declare a May Day As Soon As You THINK You Are in Danger. 

    The Incident Commanders Rules of Engagement for Firefighter Safety

    • Rapidly Conduct, or Obtain, a 360 Degree Size‐Up of the Incident.
    • Determine the Occupant Survival Profile.
    • Conduct an Initial Risk Assessment and Implement a SAFE ACTION PLAN.

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

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

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

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

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

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

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

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

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

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

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

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

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

    Understand your Response District

     

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

    • From Plywood-CDX….to
    • Particle Board- PB…..to;
    • Orient Strand Board-OSB
    • Structural Composite Lumber- SCL
    • Laminate Strand Lumber- LSL
    • Laminate Veneer Lumber-LVL
    • Structural Insulated Panels-SIP
    • Parallel Strand Lumber-PSL
    • Machine Stress Rated Lumber- MSR
    • Medium Density Fiberboard-MDF and MDL (Lumber)
    • Finger Jointed Lumber-FJL
    • Adhesives…..
    • Do some research and check these terms out for starters.
    • We’ll talk more about these components and assemblies in the near future. So get busyover the next few days during Safety Week and discover the implications these components may have in your community….

    New Materials, New Construction; New Problems

    Here’s a link to a past informative posting related to engineered systems and their relationship to firefighter safety and operations, HERE.

    There’s some great contributed information and manufacturer “insights” on the subject engineered wood I-joists and beams and firefighter safety. There are some interesting statistical extrapolations, correlations and conveniences’ that attempt to make the case. But then again, You be the judge.

     Just Look Over your Shoulder….

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

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

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

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

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

    Better Look Over your Shoulder

     

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

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

      

    Remember its Occupancy RISK not Occupancy TYPE

     

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

     

    STOP THE ENTERTAINMENT

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

    These behaviors include;

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

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

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

      

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

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

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

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

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

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

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

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

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

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

      

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

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

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

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

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

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

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

      

     

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

    Fire Behavior 101; Taking it to the Streets

    2 comments

     

    Fire Behavior

    Fire Dynamics

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

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

    Defining Fire

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

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

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

    Measuring Fire

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

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

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

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

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

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

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

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

    Heat Flux (kW/m2)
    Example
    1
    Sunny day
    2.5
    Typical firefighter exposure

    (930 F - 2500 F)

    10 CANDLES

    HRR: ~ 800 W

    Heat Transfer

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

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

    CONDUCTION

    Conduction is heat transfer within solids or between contacting solids.

    Conduction          Firefighter Conduction

     

    The governing equation for heat transfer by conduction is:

    Conduction Equation

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

    Thermal Conductivity of Common Materials

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

    CONVECTION

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

    Convection          Firefighter Convection

    The governing equation for heat transfer by convection is:

    Convection Equation

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

    These values are found empirically, or, by experiment.

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

    RADIATION

    Radiation is heat transfer by electromagnetic waves.

    Radiation          Firefighter Radiation

    The governing equation for heat transfer by radiation is:

    Radiation Equation

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

    Fire Phenomena

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

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

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

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

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

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

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

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

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

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

    This is the most dangerous stage of fire development.

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

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

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

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

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

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

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

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

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

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

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

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

    The tactical considerations addressed include:

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

    Comparison of Modern and Legacy Home Furnishings

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

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

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

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

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

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

    The Albuquerque Fire Department seeks to improve operations from past performance

    Four firefighters with the Albuquerque (NM) Fire Department were injured during operations at a three-alarm fire that injured raged through the Royal Crown Apartment Complex  in southeast Albuquerque on Friday February 4, 2011.

    The injured firefighters were among four who fell through the floor from the second story to the first while searching for residents of the, according to the Albuquerque Fire Department. Both suffered leg injuries, one had minor burn, and they were treated and released from University of New Mexico Hospital a few hours later, an AFD spokesperson said.

    According to published reports at the time of the event, the first alarm came in at 3 p.m. bringing personnel and apparatus to the three-story building at 4801 Gibson SE. First units on the scene reported heavy smoke and flames on the north side of the building.

    A crew from AFD Engine 13 entered the building and during a search rescued two uninjured residents from one apartment and also save a cat.

    At 3:40 p.m. Incident command transitioned to a defense operations to fight the fire from outside the building. The third alarm was transmitted due to the projected heavy fuel load in the large complex.

    Overall 75 fire personnel responded and operated at the alarm.

    The fire is believed to have started behind a washing machine in the first-floor laundry room. An electric cause is suspected, but AFD said the exact cause is still under investigation.

    The three-story multiple occupancy apartment complex was built in 1976 and housed 47 apartment units in 31,896 square feet of space.

    In the months since the fire, the Albuquerque Fire Department has conducted a critique and post incident assessment of the operations, mayday and close-calls and overall performance of the department. As reported in the media video leading into this article, the department has taken the results of that post incident assessment and has developed training being delivered to al personnel to increase future operational performance, efficiencies and to reduce the likely hood of a similar event from occurring.

    According to the Fire Department, they were playing catch-up from the early advancing stages of the incident and experienced difficulty in being able to make strategic strides to get ahead of the escalating incident severity, magnitude and rapid development.

    The unexpected events leading to the multiple maydays and firefighter injuries challenged incident command and operations and could have resulted in possible multiple firefighter LODDs versus the close-call, near-miss events that subsequently lead towards the efforts to undertake  critical review of the incident and operations.

    Some Insights and Learning’s from the Incident included that have resulted in enhancements;

    • Communications
    • Situational Awareness
    • Calling the Mayday
    • Radio Communications
    • Distractions and Error Prevention
    • Accountability
    • Command Response to Mayday Events
    • Communications Mayday Alerts

    It is imperative that all departments initiate at the least a formal or informal post incident critique or review. This may be at the company or station level or escalated to a more formal department level assessment and review based upon the incident parameters and conditions.

    The initiation and development of post incident analysis or assessment can be more involving and complex, with the commitment of personnel, resources and time but the benefits derived from such a review will contribute highly to the continued development and improvement of any organization. 

    There are a number of recent after action, post incident or assessments reports that have been published and have been reviewed and discussed here on CommandSafety.com.

    Take the time to review your incidents and runs at the company, station or battalion level. These reviews will identify and address low threshold, latent or emerging conditions before they escalate into apparent or root cause conditions that may contribute to significant adverse events and incidents.

    The Albuquerque (NM) Fire Department’s self-critical review of this event has identified short comings at a number of levels that they are working to improve.

    As they state in the video report, the outcome of this event could have been a lot worse than the injuries sustained and the resultant near-misses. The focus on improvements and enhancements within the functional areas of Calling the Mayday, Rapid Intervention and Mayday Communications and Operations is commendable and aligns with this year’s theme for Safety, Health and Survival Week.

    The 2011 Safety Week theme is; Surviving the Fire Ground – Fire Fighter, Fire Officer and Command Preparedness.

    Be Self-Critical and a Learning Organization

    • In the meantime think about your operations; are you self-critical and a learning organization seeking to identify gaps or areas for improvement?
    • There is a lot that can be learned from our daily responses and operations, whether they be that single company response or that multiple alarm incident. 
    • All it takes is the recognition to see things for what they are and your may not be as good as you think and the understanding and desire to identify those conditions and improve .

    Chesapeake (VA) Auto Parts Store Roof Collapse Double LODD 1996

    Roof Collapse Chesapeake VA 1996 Double LODD

    OVERVIEW

    Fifteen years ago, on March 18, 1996, two firefighters were killed in Chesapeake, Virginia when they became trapped by a rapidly spreading fire in an auto parts store and a pre-engineered wood truss roof assembly collapsed on them. The cause of the fire was an electrical short created when a power company truck working in the rear of the building drove away with its boom in an elevated position, accidentally pulling an electrical feed line from the main breaker panel at the rear of the store.

    Post-incident investigations indicate that the electrical fault may have sparked multiple points of fire origin throughout the roof structure of the building, due to improperly grounded wiring. At the time of the report issuance, this was exemplified as another incident illustrating the rapid failure of lightweight construction systems when key support components are involved in a fire. The report pointed out the importance of prefire planning and accurate size up by fire companies to determine the risk factors associated with a fire in this type of construction.

    Lessons regarding importance of initial company actions, constant re-evaluation of action plans, strong command and coordination of units on the fireground, and recognition of signs of impending structural failure were also reinforced.

    Fifteen years later, reading through any number of NIOSH, USFA or NFPA reports, similar issues, challenges and operational factors resonate and continue to shape and challenge today’s fire ground operations.

    It is without exception that the knowledge and insights being gained by the recent and past UL and NIST Research Studies coupled with the recommendations, from the NIOSH Fire Fighter Fatality Investigation and Prevention Program (HERE)

    Today’s fire ground is changing at a very rapid pace as it relates to the continued evolution, transition of engineered structural components and systems (ESS). Are you prepared, knowledgeable and understand that new strategic and tactical approaches are required?   

    One of the most significant actions initiated by the Chesapeake Fire Department was the implementation of a Truss Identification Program (TIP). Take a look at a past posting on CommandSafety.com where we published on an overview of truss and engineering component systems across the United States HERE. 

    City of Chesapeake (VA) Truss ID Program, HERE

     The following are excerpts and narrative from the USFA Technical Report Series TR-087 and NIOSH Report 96-17

    Aerial View 2010 Shopping Center Layout

     

    SUMMARY OF KEY ISSUES 

    Staffing : The first alarm response provided a small attack force with limited capabilities. The full response brought only 10 personnel. 

    Size-up : The first arriving company officer was not able to determine the location and extent of the hidden fire. 

    Pre-fire plan information: This complex required a pre-fire plan due to the complex arrangement, multiple occupancies, mixed construction, lack of fixed protection, limited access and difficult water supply problems. The first-due company did carry a pre-fire plan that showed the layout of the shopping center and the floor plan for the auto parts store, but the prefire plan was not referenced by the crew during the fire. 

    Delayed response: The first arriving company was on the scene alone for several minutes with only 3 personnel. The back-up companies had long response times. The lack of evidence of a working fire prompted the initial incident commander to return some of the responding units, resulting in even longer response times. 

    Water supply: The first-in company did not establish a water supply. This required the second engine company to be committed to this task. 

    Incident command: The battalion chief was faced with a complicated and rapidly changing situation. He was not able to effectively transfer command from the initial officer and direct the operations of widely separated units. 

    Operational risk management:The officers involved in the initial part of the operation had to make critical risk management decisions with limited information. 

    Accountability: Accountability for the personnel operating in the hazardous area was not established prior to the structural collapse. As the situation became critical, no one realized that a crew was still inside the building. 

    Rapid intervention crew:  Additional crews did not arrive in time to assist the crew that was in trouble inside the building. 

    Radio communications: The lack of a clear radio channel for fire ground communications caused serious problems with command and control of the incident, including the failure to maintain communications with the crew inside and the failure to hear their request for assistance. 

    Lightweight construction: The roof collapsed quickly and with very little warning. This should be anticipated with a lightweight wood truss roof assembly. This hazard was not recognized by the crews on the scene. 

    BUILDING DESCRIPTION - Construction and History 

    The fire occurred in a modern, lightweight construction building that was added to an existing strip mall in 1984. The older mall on exposure side four was separated from the fire building by a masonry fire wall and was constructed with masonry walls and a steel bar-joist roof structure. The exposures on side two consisted of additional stores that were similar in construction to the auto parts store. There were no exposures on sides one and three. 

    The auto parts store was constructed with two masonry exterior walls and two wood frame exterior walls, with a lightweight wood truss roof assembly. It was approximately 120 feet deep and 50 feet wide, providing about 6,000 square feet of open display and storage space. The roof assembly was a pre-engineered lightweight wood truss assembled from 2 x 6 top and bottom chords, with 2 x 4 web members held together with metal gusset plates. 

    • There were no interior bearing walls or supports for the roof structure. At one end, the trusses were supported by a wood plate that was bolted to a metal beam.
    • The other end rested on top of the concrete block wall. Each truss was separated by 24 inches and they were covered with 1/2 inch CDX plywood sheathing under a two-ply rubber membrane.
    • A drywall ceiling was attached to the underside of the trusses, creating a truss void space (truss loft) 24 to 36 inches above the ceiling.
    • A sheet rock divider was located in the middle of the truss void as a draft stop. The roof had a slight pitch.
    • Three air handling units were on the roof of the building, with an estimated combined weight of 3,000 pounds. It is not known when these units were installed and they may have represented an unanticipated dead load on the roof assembly.
    • There was no indication that the trusses had been reinforced to support the extra weight of these units.
    • The original truss roof structure collapsed during the construction of the building, injuring three workers.
    • Most of the trusses were damaged and had to be replaced at the time. The fire building was occupied by Advance Auto Parts, a chain distributor of automobile part and lubricants. The store was designed with an open retail area containing display racks for goods.
    • A long counter ran from front to back behind which was shelving for additional auto parts. Waste oil and batteries were kept in a rear storage area separated from the front of the store by a drywall wall.
    • The southwest corner of the building contained employee restrooms which had a small water heater located in the ceiling space just above them. The main entrance to the store was through two large glass doors at the front of the building. A delivery and service entrance was located in the rear and a 40 foot trailer was parked behind the building and used for additional storage.

    THE FIRE 

    At approximately 11:00 a.m. on March 18, 1996, a power company employee set up a service truck at the rear of the Indian River Shopping Center in Chesapeake, Virginia. The worker was going to disconnect the electrical power to a customer who had not paid an electrical bill. The customer, a cocktail lounge and bar, was located adjacent to Advance Auto Parts. In preparing to disconnect service, the power company worker elevated the articulating boom on his truck to roof level. Faced with the immediate loss of power, an employee of the lounge paid the electrical bill while the power company employee was beginning work, and went to the back of the store to show the receipt. 

    A stamped receipt indicates the bill was paid at 11:16 a.m. at a supermarket also located in the shopping center. The power company employee, working from the bucket of the articulating boom, lowered the boom and verified the receipt. Although the bucket had been lowered, the hinged elbow of the articulating boom remained elevated. The employee then radioed his supervisor from the cab of his truck, and received instructions not to disconnect power. 

    The power company employee then attempted to drive the service truck away, forgetting to secure the boom, which snagged on a power line feeding the meter at the rear of the Advance Auto Parts Store. This caused a phase-to-phase and phase-to-ground arcing fault at the store’s electrical meter, starting the fire. The power company employee immediately stopped, exited his truck, and cut the remaining power connections to the meter at the rear of Advance Auto Parts. 

    Initial Actions Prior to Calling 911 

    After cutting the power line to the building, the power company employee removed the meter, noticed smoke coming from the meter base, notified his office and requested that another power company crew and a supervisor come and assist him. 

    • An employee of the Advance Auto Parts Store came to the rear of the building and met the power company employee, telling him that the store had lost electrical power and that a fire was being extinguished inside the building.
    • Another Advance Auto Parts employee discharged a dry chemical fire extinguisher on the spot fire that had started near the hot water heater above the employee restrooms.
    • All believed the fire had been extinguished at this time.
    • At 11:29 a.m., the Chesapeake Fire and Police Emergency Operations Center received a 911 call from Advance Auto Parts reporting a problem with the fuse box in the store.
    • The Chesapeake Fire Department was dispatched to a report of a fuse box sparking at 4345 Indian River Road at the Advance Auto Parts store.

    Emergency Response 

    • Initial response consisted of two engines, a ladder company, and a battalion chief, for a total of 10 personnel.
    • Engine 3 was the first due arriving company, responding from quarters. Engine 1 and Ladder 2 also responded.
    • Battalion 1 was dispatched as the command officer, but requested that Battalion 2 cover the assignment, since he was out of position.
    • Battalion 2 acknowledged the request, and he responded with the first alarm companies.
    • Engine 3’s crew consisted of three personnel: a driver/pump operator; Firefighter- Specialist John Hudgins, serving as Acting Lieutenant for the shift; and Firefighter- Specialist Frank Young, detailed to the station for the day, was riding in the jump seat. Engine 3 was responding in a reserve engine that had a 500 gallon water tank.

     

    Initial Size-Up and Company Actions 

    At approximately 11:35 a.m., about five and a half minutes after dispatch, Engine 3 arrived on the scene at the front of the strip mall. 

    • Hudgins reported “a single-story commercial structure, nothing showing from the front. Engine 3 is in command.”
    • Engine 3 took a position in front of the Advance Auto Parts Store. Hudgins and Young entered the structure from the front of the building to investigate.
    • Conditions were clear in the store, and there was no visible smoke or flames showing. They discovered light smoke near the electrical panel in the rear of the building, and radioed to Battalion 2 that they had a fire and were checking for extension.
    • Acting Lieutenant Hudgins then radioed for Engine 3’s driver to reposition the apparatus to the rear of the building.
    • Hudgins then radioed to Battalion 2, who had not yet arrived on the scene, that Engine 3 and Ladder 2 could handle the incident. Battalion 2 and Engine 1, the second due engine company, both went in service.

     Engine 3 Reports They Are Trapped, Roof Collapses 

    At approximately 11:49 a.m., almost 20 minutes after the initial dispatch time, Hudgins radioed that he and Young could not get out of the building. Battalion 2 radioed back that he could not understand their transmission. Hudgins then radioed that they needed someone to come to the front of the building and get them out. Again unable to understand their transmission, Battalion 2 radioed for any unit on the fireground to advise him if they heard the message that was transmitted. 

    • Engine 4 responded that they were unable to copy the transmission.
    • Engine 14 then marked on the scene and was instructed by Battalion 2 to lay a supply line to the front of the building. Battalion 1, enroute to the fire on the second alarm, radioed to Battalion 2 that it sounded like someone was trapped inside.
    • Battalion 3, also enroute, radioed that he would be on the scene momentarily and would assist.

    At this time, Ladder 2’s crew was setting the outriggers and preparing to elevate their aerial ladder for defensive operations. 

    • In the short time it took to accomplish the stabilization of the ladder truck, the front of the store became fully involved, the building contents ignited, and the roof collapsed.
    • Due to the radiant heat, Ladder 2 was forced to retract their outriggers and reposition to a safer defensive position on side one of the structure, and set up the aerial again.
    • Ladder 2’s crew did not hear Engine 3’s transmission that they were trapped.
    • Simultaneously, Engine 1 ran out of supply line about 200 feet short of the hydrant. Engine 2, responding on the second alarm, picked up the hydrant that Engine 1 was attempting to reach and laid a supply line to side one.
    • The driver of Engine 1 attempted to contact his officer by radio to advise that he could not reach the hydrant, but could not get through due to heavy radio traffic.
    • He parked the engine in the roadway, donned his SCBA, and went to the rear of the building to report to his Captain and rejoin his crew.
    • Battalion 3 arrived on side one about this time and radioed for all companies to switch to channel two, an alternate fireground tactical frequency.

    Driven by the northerly wind and the draft created by the burning contents of the structure, the fire at the rear had grown in such intensity that personnel were forced to move Engine 3. Assisted by employees of the power company, Engine 3 was moved back away from the rear of the building. At 11:55 a.m., about 26 minutes after dispatch, the Captain of Engine 1, with his crew at the rear of the building, confirmed to Battalion 2 that “I got men on the inside from Engine 3, and the lines have been burned. I do not know their status, and we still have no water to go in after them.” 

    Battalion 3 met with Battalion 2 and discussed that they may have lost a crew inside. Battalion 3 assumed command and Battalion 2 went to the rear of the building to coordinate rescue efforts. There, Battalion 2 met with the Captain from Engine 1. 

    By this time, the building was fully involved and no rescue efforts could be mounted until the fire was knocked down. Officers at the front and the rear attempted to conduct a personnel accountability report (PAR) to determine who was missing and where they might be located. 

    • An engine company responding on mutual aid from the Virginia Beach Fire Department was flagged down, connected to Engine 1’s supply line, and completed the water supply to a hydrant behind the shopping center within the City of Virginia Beach. Engine 3 was forced to move back once again, and the supply line was disconnected from Engine 3 and used to supply water to Engine 4, a telesquirt that was positioned for defensive operations at the rear.

    Extinguishment and Body Recovery 

    The fire spread to the attic of the exposures on side two and was held in check by the fire wall on side four of the building. The fire was brought under control as the contents of the auto parts store burned off and several aerial streams were put into operation. After the fire was extinguished, a search for the missing firefighters was initiated. After the bodies of the firefighters were located, they were  removed from the fire building by members of the Virginia Beach Fire Department, and transferred by members of the Chesapeake Fire Department to medic units. 

    The body recovery was supervised by the Chesapeake Fire Department Fire Marshal’s Office and documented. An investigation was immediately started by the Chesapeake Fire Department Fire Marshal. 

    ANALYSIS 

    Fire Cause and Flame Spread 

    • The fire was caused by the electrical short created when the power company truck struck the power line to the building. Investigation by the City of Chesapeake Electrical Inspector after the fire revealed that the meter contained wiring that appeared to have been tampered with and did not comply with the electrical code.
    • Several connections at the meter had been double-lugged, connecting multiple wires to single terminals. Additional investigation by Virginia Power revealed that the building may have been improperly grounded, leading to numerous hot connections when the short circuit occurred. The main fuse did not trip at the breaker panel and the wiring on all three air handling units had been fused. This probably resulted in the ignition of multiple spot fires in the truss loft above the store.
    • It appears that the fires in the truss loft were still relatively minor when Engine 3 arrived, but the fire spread rapidly throughout the space due to the light wood construction.
    • The wind drawn from the open doors at the front of the building also promoted rapid fire growth. This would have created a tremendous hidden fire in the wood truss loft area despite clear conditions inside the structure.
    • Reports of heavy smoke and fire conditions on the roof at the same time Engine 3’s crew was calling for pike poles and personnel to come inside are indications towards this scenario.
    • The interior of the auto parts store contained racks of auto parts and supplies, including oil, lubricants, rubber, and plastic parts. The contents were packed closely together and stored in tall racks near the ceiling.
    • Once the fire had broken through the ceiling in the rear of the building, these contents would have quickly reached their ignition temperatures, creating flashover conditions in the rear of the store as the fire progressed, trapping the firefighters and forcing them to seek an exit at the front of the store.

    Roof Collapse 

    • The collapse of the pre-engineered truss roof occurred approximately 21 minutes after the time of dispatch, and within 35 minutes of the initial accident, that caused the electrical short.
    • The structure appears to have collapsed within 10 to 12 minutes after the truss space became heavily involved.
    • The collapse of similar truss assemblies under fire conditions within this time period has been well documented.
    • Post-incident investigations indicate that this truss assembly may have been weakened by deficiencies in the connection of the trusses to the beam on the east side of the building.
    • Also, the dead load of the three air conditioning units may have contributed to the rapid failure of the roof.
    • Reports from firefighters on the scene indicate that a partial failure of the truss assembly may have occurred in the rear of the building, followed shortly by the failure of the entire roof assembly.
    • It is possible that the crew of Engine 3 was trapped by the partial collapse of the roof in the rear, or by the collapse of racks containing auto parts in the building, or by the rapid spread of the fire and smoke which had broken through the ceiling.
    • It is also possible that a combination of these events occurred simultaneously. The failure of the entire roof assembly and complete involvement of the interior of the building with fire took place within one minute after the firefighters radioed for help, before any reaction to assist them could take place.

      

      

    Fire Operations 

      

    Initial Response - The first alarm assignment was overwhelmed by the situation, the circumstances, and the unusual sequence of events that occurred at this incident. It is evident that a larger force would have been needed to initiate an effective offensive or defensive operation for a working fire in a 6,000 square foot commercial occupancy, with attached exposures on two sides, with or without the unusual complications. 

    • The response of two engine companies, one ladder company and a battalion chief, provided a total of 25 only 10 personnel on the initial assignment.
    • The individual companies, which responded with three person crews, had limited capabilities to perform tasks independently.
    • This incident generated only a single call to 9-1-1 reporting an electrical problem.

      

     

    LESSONS LEARNED AND REINFORCED  

    1. RISK ASSESSMENT is the primary responsibility of the incident commander. 

    This incident presented a very high risk to the firefighters who were attempting to make an interior attack. However, the risk factors were not recognized and the interior crew was not directed to abandon the building. Risk assessment should be a continual process, particularly when a situation is changing very quickly. 

    2. ACCOUNTABILITY is an essential function of the Incident Command System. 

    The location and operation of the initial attack crew was not tracked according to the incident command system that was in effect at the time of the fire. The system must keep track of the location, function, status, and assignment of every individual unit or company operating at the scene of an emergency incident. In order to be effective, the accountability process must be routinely initiated at the beginning of every incident and updated as the incident progresses and units are reassigned to different tasks. 

    3. TACTICAL RADIO CHANNELS are essential for firefighter safety. 

    The fireground operations were conducted on the same radio channel as the routine dispatch and transfer of additional units, hampering the fireground communications during the important early stages of the incident. Designated radio channels should be set aside specifically for communications between the incident commander and the units operating at the scene of an incident. The exchange of information, orders, instructions, warnings, and progress reports is essential to support safe and effective operations. Tactical channels should be assigned early and routinely to avoid the confusion that occurs when units that are already working are directed to switch to a different radio channel. 

    4. FIRE OPERATIONS must be limited to those functions that can be performed safely with the number of personnel that are available at the scene of an incident. 

    The initial response to this incident did not provide enough resources to safely initiate an effective interior attack for the situation that was encountered. The first arriving company initiated interior operations that could not be adequately performed or supported with the limited number of personnel at the scene or responding. The delayed arrival of back-up companies increased the risk exposure of the first due company. The situation called for a more conservative initial attack plan and/or an early retreat when the magnitude of the fire became evident. 

    5. WATER SUPPLY is a critical component of a safe and successful operation. 

    The failed attempt to establish an adequate and reliable water supply for the interior attack was a critical problem at this incident. This task occupied the second due engine company which was needed to provide either a back-up hose line to support the interior attack or a rapid intervention crew. 

    6. LIGHTWEIGHT WOOD TRUSS CONSTRUCTION is prone to rapid failure under fire conditions. 

    If the construction of the building had been known or recognized, the early failure of the roof structure should have been anticipated and the interior crew should have been withdrawn. This requires pre-fire planning to identify high risk properties and a reliable system to label the building or to inform the responding units of the risk factors of the building. It is usually difficult or impossible to make this determination when the building is burning.

    Fire-Related Firefighter Injuries Report Issued

    No comments

    The Federal Emergency Management Agency’s (FEMA) U.S. Fire Administration (USFA) issued a special report examining the details of firefighter injuries sustained on the fireground or while responding to or returning from a fire incident.

    The report, Fire-Related Firefighter Injuries Reported to NFIRS , was developed by USFA’s National Fire Data Center and is further evidence of FEMA’s effort to reduce the number of firefighter injuries through an increased awareness and understanding of their causes and how they might be prevented.

    The report is part of the Topical Fire Report Series and is based on 2006 to 2008 data from the National Fire Incident Reporting System (NFIRS).

    According to the report:

    • An estimated 81,070 firefighter injuries occur annually in the United States.
    • 49 percent of firefighter injuries occur on the fireground and 6 percent occur while responding to or returning from a fire incident.
    • Overexertion/strain is the leading cause of fire-related firefighter injuries at 25 percent.
    • 38 percent of all fire-related firefighter injuries result in lost work time.
    • The majority of fire-related firefighter injuries (87 percent) occur in structure fires.
    • On average, structure fires have more injuries per fire than nonstructure fires.
    • Firefighter injury fires are more prevalent in July (10 percent) and peak between the hours of 2 and 5 p.m.

    Topical reports are designed to explore facets of the U.S. fire problem as depicted through data collected in NFIRS. Each topical report briefly addresses the nature of the specific fire or fire-related topic, highlights important findings from the data, and may suggest other resources to consider for further information. Also included are recent examples of fire incidents that demonstrate some of the issues addressed in the report or that put the report topic in context.

     

    •  Eighty-seven percent of firefighter injuries reported to NFIRS from 2006 to 2008 were associated with structure fires
    • Three times as many firefighter injuries occur in residential structures than in nonresidential structures, tracking with overall residential/nonresidential fire incidence.
    • Overall, firefighter injuries in residential struc-tures account for 65 percent of firefighter injuries, a majority of which occur in residential building fires.
    • Building fires also make up more than half of the firefighter injuries in structure fires on nonresidential properties.
    • Outside, vehicle, and other fires combined represent 13 percent of firefighter injuries from 2006 to 2008.

     

    Fire-Related Firefighter Injuries by Affiliation and Age

    • Injuries to career firefighters are the largest share (66 percent) of the reported injuries. Nationally, only 28 percent of the fire service is career firefighters.
    • Injuries to career firefighters tend to occur in midcareer (ages 30–45) with the peak between ages 35 and 39. Injuries to volunteers, on the other hand, are sustained predominately by the younger members of the organization. Firefighters under the age of 25 account for 29 percent of injuries in the volunteer service.
    • Career firefighters also experience proportionally more lost-time injuries than their volunteer counterparts (approximately 2 to 1). Volunteer firefighters, on the other hand, receive far more no lost-time injuries.
