Engineered Structural Support (ESS) system: Been in the Field lately?

No comments

Been in the field lately looking at your buildings under construction? Here’s a new look at a common Engineered Structural Support (ESS) system.

Here’s  today’s Taking it to the Streets session; Take a look at this Engineered Structural Support (ESS) system. There are two critical component systems depicted here in this photo- can you tell what they are? Take a close look at the ESS T…russ components. They are nothing new, but they do cause a stir when they make their way back into main stream fire service discussions as firefighters and officers “rediscover” these type of systems, their use, presence and operational risk and profiling.

So let’s start the dialog:

  • Can you name the type of ESS Truss, the inherent characteristics, design and function | typical applications | risks and operational concerns.
  • What impact will fire impingement have on the ESS assembly in either foor or roof systems?
  • How can you identify these assemblies and building characteristics unpon arrival?
  • What fireground strategies and tactics would you employ upon arrival at an occupancy with this type of ESS?
  • Don’t forget to look at the second system component that I mentioned earlier;
  • Can you identify it? Its relationship to the other system and other inherent performance issues?

 

 

Lots to talk about, look at and share. Any street stories to share-please post. I’ve got a few more in this series to post after we get some dialog and insights….
We’ve cross posted this on our Buildingsonfire Facebook page (HERE), if you haven’t checked it out, please follow the link, there’s been some great discussions and insights being shared from around the country…

Attic Fires in Residential Buildings Report

No comments
 
The Federal Emergency Management Agency’s (FEMA) U.S. Fire Administration (USFA) has recently issued a special report examining the characteristics of Attic Fires in Residential Buildings (PDF, 884 Kb). Developed by USFA’s National Fire Data Center, the report is based on 2006 to 2008 data from the National Fire Incident Reporting System (NFIRS).

According to the report:   

  • An estimated 10,000 attic fires in residential buildings occur annually in the United States, resulting in an estimated average of 30 deaths, 125 injuries, and $477 million in property damage.
  • The leading cause of all attic fires is electrical malfunction (43 percent).
  • The most common heat source is electrical arcing (37 percent).
  • Almost all residential building attic fires are nonconfined (99 percent) and a third of all residential building attic fires spread to involve the entire building.
  • Ninety percent of residential attic fires occur in one- and two-family residential buildings.
  • Residential building attic fires are most prevalent in December (12 percent) and January (11 percent) and peak between the hours of 4 and 8 p.m. 

Attic Fires in Residential Buildings is part of the USFA’s Topical Fire Report Series. Topical reports explore facets of the U.S. fire problem that USFA shares with fire departments and first responders around the country to help them keep their communities safe. Each 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.   

  • The location of the attic provides many difficulties for firefighters when extinguishing the fire. Careful planning goes into deciding the best way to extinguish an attic fire.
  • Firefighters must decide whether to fight the fire from above or below, both of which present many difficulties. In both instances, firefighters have to consider that roofs or ceilings may collapse. The large amounts of water used to extinguish the blaze causes the insulation and wood beams to become saturated. Firefighters have been known to fall through the roof into the attic or through the attic into the floor(s) below.
  • In addition, not all attics have flooring. If firefighters enter the attic, they must be careful not to step outside the flooring area since they risk falling through the ceiling.
  • The construction of the attic is another area that presents difficulties to firefighters. Older and newer homes are constructed using different techniques. Older homes tend to have roofs that are framed with larger sized lumber, 2 by 6 inches.
  • These attics usually provide a continuous attic space with a peak as high as 8 feet. Conventional attics are not generally compartmentalized like many new home attics. Newer home attics typically employ a truss-framed construction that involves smaller wood boards placed in “A” (or triangular) shapes throughout the attic from the ceiling to the floor.
  • This construction can be difficult for a firefighter to navigate.
  • In addition, wood members in truss-framed construction can conceal fires and make extinguishing the fire more difficult.  In large new homes and multifamily dwellings, many attics are constructed with fire stops, which can be as substantial as 2-hour, fire-resistance rated walls.
  • These help limit the spread of the fire from the attic to surrounding areas.

Collapse of Bowstring Truss Roof Seriously Injures Fire Fighter

5 comments

Fire suppression operations on Alpha side prior to collapse. Firefighter is seen in the immediate collapse zone

The NIOSH Fire fighter Investigation and Prevention Program, Fire Fighter Fatality Investigation Reports  recently released Report # F2009-12 for a Near-Miss event that seriously injured a firefighter  wih significant learnings;   HERE   

Through the Fire Fighter Fatality Investigation and Prevention Program, NIOSH conducts investigations of fire fighter line-of-duty deaths to formulate recommendations for preventing future deaths and injuries. The program does not seek to determine fault or place blame on fire departments or individual fire fighters, but to learn from these tragic events and prevent future similar events.  

On May 21, 2009, a 36-year-old male career fire fighter was seriously injured while operating in a non-designated collapse zone of a commercial structure when an overhang of a bowstring truss roof system collapsed and struck him. The first arriving company officer reported a working fire in a single story Type II warehouse.  

The officer looked under a steel roll-up door that was raised approximately three feet off of the ground and saw heavy fire towards the rear of the structure from floor to ceiling. Per department procedures, the first arriving companies went into a “Fast Attack” mode. Crews attempted but were unable to enter the structure because the steel roll-up door wasn’t functioning and the man door was heavily secured.  

The department’s Deputy Chief arrived on the scene 9 minutes after the initial crew and determined that the fire should be fought defensively, however, this command was not relayed over the radio or verified with all crews. A crew was operating a 2 ½-inch handline just outside the structure approximately 20 minutes after the first apparatus arrived when the overhang collapsed and trapped the nozzleman.  

Key contributing factors identified in this investigation include:  

  • scene management and risk analysis,
  • a well-involved fire in a structure with hazardous construction features, and
  • fire fighters operating within a potential collapse area.

STRUCTURE

The building was constructed in 1954 and was a single-story warehouse of Type IV construction. The dimensions of the building were 110 feet deep by 50 feet wide, covering approximately 5,500 square feet. The height of the building was approximately 20 feet. The occupancy use of the building was commercial and it operated as a warehouse. The building’s structural system consisted of masonry block bearing walls with four heavy timber wood bowstring trusses for a roof system.  

The heavy timber wood trusses had a 50-foot clear span to the bearing walls and were located 19 feet 9 inches on center. The heavy timber wood truss assemblies were 48 feet 7 inches in depth and were constructed of 4-inch x 6-inch timber cords and webs connected with bolt fasteners with a metal splice plate and bolt configuration at the bottom chord span. Solid 2-inch x 10-inch wood purlins located on 24-inch centering spanned perpendicular to the truss assembly with a ¾-inch plywood roofing deck. The roofing system assembly was exposed and did not have a membrane or other passive fire protection features.  

Aerial view of Building

Structural stability to the heavy timber truss units was provided by 2-inch x 6-inch wood cross bracing in conjunction with the stability provided by the wood purlins and plywood deck roofing membrane. The structure contained six skylights that were 3 feet by 6 feet .  

The overall integrity and structural stability of this type of structural support and roofing system is contingent upon all components maintaining their connections and load bearing or load transferring capacity.  

The A-side was a non-load bearing wall that showed the traditional arched roof profile that is consistent with bowstring roof construction. The A-side wall also consisted of what appeared to be an overhanging or cantilevered façade that was covered by stucco.  The overhang was part of the original construction that tied back into the bowstring truss system. The fire building was integrated into a block of commercial occupancies so that only the A-side was accessible for interior fire fighting activities.  

The B-side exposure of the building was adjacent to a parking lot and was of masonry construction without any windows or doors. The C-side and D-side exposures were of similar size and construction and shared party walls between their respective sides. A pre-plan had not been completed for this structure.  

Similar Interior Construction Features

At the time of the fire, the building was used as a place to grow marijuana illegally. The man door was heavily barricaded and a false wall was constructed to shield the operations from the exterior when the roll-up door was lifted. The electric service was severed and rerouted to circumvent the electric meter in order to conceal the operations.  

TRAINING and EXPERIENCE

The state requires all career fire fighters to complete training equivalent to NFPA, 1001 Standard for Fire Fighter Professional Qualifications, Fire Fighter 1. The department provides up to 17 months of training to certify fire fighters to NFPA Fire Fighter 1 and 2 qualifications, and a one year probationary period of supervised training for department fire fighter certification. The additional training during this probationary time focuses on driver training, pump operations, aerial ladder operations, and specialized equipment training.  

  

Alpha Side

Injured Fire Fighter
The injured fire fighter had more than six years of experience and had completed department provided classroom/field training on topics such as: live fire training, rapid intervention crew (RIC) procedures, and hazardous materials.  

Initial Incident Commander (IC)
The first due company officer had more than 15 years of experience with the department. Six of those years were as a fire fighter, seven years as a cross-trained paramedic, and 18 months as a lieutenant in an acting and permanent appointment at the time of the incident. The initial IC had completed the department provided five four-day sessions on critical fireground topics that were required for newly appointed lieutenants. This training included the following topics: building construction, incident management system (IMS), size-up, company operations, and rapid intervention company (RIC) operations.  

Incident Commander (IC)
The IC had more than 30 years of experience and had completed department provided classroom/field training in topics such as: health and safety 1, 2, 3 & 4; fire command; fire instructor; fire investigation; fire management; fire officer; fire prevention; incident command; incident safety officer;  and RIC procedures.  

Incident Safety Officer (ISO)
The battalion chief who was assigned as the ISO for this incident had more than 20 years of experience and had completed department provided classroom/field training in topics such as: health and safety 1,2,3,and 4; fire command; fire instructor; RIC procedures; hazardous materials; heavy rescue 1 and 2; training officer development; wildland training; and emergency vehicle operations.  

INVESTIGATION INSIGHTS

At 0446 hours central dispatch received an alarm for a reported structure fire with fire and smoke showing at a commercial occupancy. Engine 42 (E42) was the first apparatus on the scene at 0449 hours and the officer reported on the radio a working fire in a single story Type II warehouse. Note: The classification of Type II was incorrect. This building was a Type IV construction due to the heavy timber bowstring trusses.   

The E42 Lieutenant and a fire fighter ran to a steel garage roll-up door that was raised approximately three feet off of the ground on the left of the A-side wall. The E42 Lieutenant looked under the door and saw heavy fire towards the rear of the structure from floor to ceiling. The E42 Lieutenant and the fire fighter attempted to raise the door but could not due to the door being dislodged from its track. Note: The door frame had been compromised by the fire and the tracks were not attached to the wall. They immediately went to a man door to the right of the A-side. It was locked and had heavy security bars. The E42 Lieutenant called Battalion Chief 6 for a truck company to perform forcible entry.  

The E42 Lieutenant ordered the crew to prepare the multiversal, which is a master stream appliance that can be used on the ground, and 2 ½-inch handlines to attempt to attack the fire through the roll-up door. Note: Per department policy, all first arriving companies and officers go to work in a “fast attack” mode. At approximately 0452 hours Engine 32 (E32) and Engine 17 (E17) pulled onto the road leading to the structure within a block from the structure.  

Both the E32 and E17 officers immediately radioed dispatch and requested a second alarm due to the heavy fire self-venting from the roof of the structure. E32 proceeded to the front of the structure, dropped off two 3-inch supply lines for E42, and went to hook up to a hydrant to supply E42. E32 used a 10-foot section of 3-inch supply line to hook up to one side of the hydrant. They used another 50-foot section of 3-inch supply line to hook up to the other side of the hydrant.  

During this same time, at approximately 0452 hours, BC6 arrived on the scene, called to ensure a second alarm, and conducted a size-up of the front of the building and the operations taking place. A division chief arrived on the scene at 0453 hours, assumed incident command (IC), and ordered BC6 to protect Exposure D. The E17 officer and fire fighters [including the injured fire fighter (IFF)] walked up to the front of the structure and saw the E42 and E32 crews attempting to deploy the multiversal and two 2 ½-inch handlines off of E42. Note: The crews were having difficulty due to having to assemble the three 50-foot sections of 2 ½-handlines from a bag stored on top of each apparatus. The crew also removed the multiversal from on top of E42 and placed it on the ground for operation.   

The IFF took the nozzle of one of the 2 ½-inch handlines and was backed up by an E17 fire fighter. Two additional fire fighters manned the other 2 ½-inch handline and were protecting the D-exposure by shooting water onto the roof from over 20 feet away from the structure. The E17 officer and E17 fire fighter operated the multiversal over 20 feet back from the roll-up door and attempted to shoot water through the opening where the door had pulled away from the wall. The E17 officer noticed that both handlines were ineffective and he went to check on the IFF. The IFF’s handline stream was ricocheting off of the man door and the four windows above it.  

The L7 crew had assembled handtools on the ground in front of the Command Post. The E17 officer took a saw to the man door in an attempt to open it so that the handline could be effective. He quickly determined that the saw would not work due to the door being so heavily protected. Battalion Chief 09 arrived on the scene at 0500 hours and was designated by the IC as the Incident Safety Officer (ISO) at approximately 0504 hours. He instructed the E17 officer to attempt to open the door with a rabbit tool; the E17 officer informed the ISO he wasn’t sure where the truck company kept it. Immediately after, BC6 ordered the E17 officer to take his saw to the roll-up door and cut an opening for access.  

He cut a three foot by six foot hole in the door and was attempting to cut across the door when he was tapped on the shoulder by the Deputy Chief which he assumed meant he was to quit. During this time, BC6 had received orders from the Deputy Chief to pull everyone back from the front of the building and to ensure that no one went inside. Note: According to interviews conducted by NIOSH investigators, this is the first time that anyone on the scene communicated the need to go defensive to the initial arriving officers. It was reported to the NIOSH investigators that every officer who reported to the command post was given face-to-face directions that the fire was defensive and that no one was to enter the building. This tactical decision was not relayed over the radio.   

BC6 ordered the crews from E42 and E17 to set up and direct a master stream into the hole through the roll-up door from a distance. The crews fought fire from a distance with the master stream for several minutes. The IFF and the E17 fire fighter continued to fight fire with the handline moving from the roll-up door to the man door several times. Note: This crew, along with many other members that were interviewed, reported not receiving any orders regarding a defensive operation.  

BC6 noticed that the fire had compromised an electrical weather head and that the power lines were going to come down soon. He turned to order crews to vacate the area where the power lines would possibly fall when he heard a large crash. He turned back and saw that the roof overhang had fallen onto the sidewalk. The collapse trapped the IFF who was operating the handline into the windows along with the E17 fire fighter. Members immediately rushed to the scene to rescue the trapped fire fighter.  

  • The IC ordered BC6 to command the rescue crew and complete a personnel accountability report (PAR) for the fireground.
  • A full PAR was completed and the trapped fire fighter was removed and transported to a local hospital. 

Collapse into the street on Alpha Side

 

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

  • ensure that they have consistent policies and training on an incident management system
  • develop, implement and enforce written standard operating procedures (SOPs) that identify incident management training standards and requirements for members expected to serve in command roles
  • ensure that the incident commander conducts an initial size-up and risk assessment of the incident scene before beginning fire fighting operations
  • ensure that the first due company officer establishes a stationary command post, maintains the role of director of fireground operations, and does not become involved in firefighting efforts
  • implement and enforce written standard operating procedures (SOPs) that define a defensive strategy
  • ensure that policies are followed to establish and monitor a collapse zone when conditions indicate the potential for structural collapse
  • train all fire fighting personnel on building construction and the risks and hazards related to structural collapse
  • conduct pre-incident planning inspections of buildings within their jurisdictions to facilitate development of safe fireground strategies and tactics

NIOSH RECOMMENDATIONS  

  • Recommendation #1: Fire departments should ensure that they have consistent policies and training on an incident management system.
  • Recommendation #2: Fire departments should develop, implement and enforce written standard operating procedures (SOPs) that identify incident management training standards and requirements for members expected to serve in command roles
  • Recommendation #3: Fire departments should ensure that the incident commander conducts an initial size-up and risk assessment of the incident scene before beginning fire fighting operations
  • Recommendati on #4: Fire departments should ensure that the first due company officer establishes a stationary command post, maintains the role of director of fireground operations, and does not become involved in firefighting efforts.
  • Recommendation #5: Fire departments should develop, implement and enforce written standard operating procedures that define defensive fire fighting operations.
  • Recommendation #6: Fire departments should ensure that policies are followed to establish and monitor a collapse zone when conditions indicate the potential for structural collapse.
  • Recommendation #7: Fire departments should train all fire fighting personnel in building construction and in the risks and hazards related to structural collapse.
  • Recommendation #8: Fire departments should conduct pre-incident planning inspections of buildings within their jurisdictions to facilitate development of safe fireground strategies and tactics.
  • 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 tens and hundreds of thousands of structures within their jurisdiction, it is a challenge to establish an effective preplanning system. Priority should be given to those having elevated or unusual fire hazards and life safety considerations.
  • One tool for fire departments to use in assessing their risks for structures within their jurisdictions is the mnemonic, BECOME SAFE: (HERE) 
    • Building
    • Evaluation
    • Construction/occupancy
    • Operational hazards
    • Manage time and elements
    • Engagement
    • Situational awareness
    • Assessment and risk analysis
    • Fire behavior and effects
    • Evaluate and execute  
 
 

BECOME SAFE by CJ Naum

In this incident, the presence of the bowstring truss presented an elevated life safety consideration in the event of a fire. A thorough building inspection and pre-incident plan for a single-story, bowstring truss occupancy in this area could have potentially identified the hazards typically associated with this type of construction such as: ceiling voids, fuel loads, non-permitted renovations, roof construction, HVAC location, and exit locations. Evaluating the construction features and layout of the structure allows the fire department the opportunity to determine a response protocol for the specific identified hazards and to develop fireground strategies and tactics (ventilation strategies, avenues of fire spread, proper attack line selection, etc.) before an incident occurs.  

The construction features of occupancy (bowstring truss), possible commercial fuel loads and access restrictions suggested large volumes of water would be necessary to fight a major fire at the site. A more complete pre-planning process, involving individual fire companies within their response territory 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 and building code officials should be cross-trained on each-others’ duties and responsibilities.  

Fire fighters should have a basic understanding of what a code violation is and how to report them during a pre-plan, and building code inspectors should have a basic understanding of fire fighter safety issues during their inspections. The relay of this information could be used to facilitate dynamic risk management and enhanced command and control.

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

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

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

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

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

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.
  • Report HERE

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.
  • Report HERE

NIOSH ALERT: Preventing Injuries and Deaths of Fire Fighters due to Truss System Failures

  • Fire fighters may be injured and killed when fire-damaged roof and floor truss systems collapse, sometimes without warning.
  • The National Institute for Occupational Safety and Health (NIOSH) requests assistance in preventing injuries and deaths of fire fighters due to roof and floor truss collapse during fire-fighting operations. 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.

USFA Incident Reports (Stop History Repeating Events-HRE)

  • USFA provides information resources in many formats, including books, pamphlets and DVD’s, free of charge.
  • The U.S. Fire Administration develops reports on selected major fires throughout the country. The fires usually involve multiple deaths or a large loss of property. But the primary criterion for deciding to do a report is whether it will result in significant “lessons learned.” In some cases these lessons bring to light new knowledge about fire–the effect of building construction or contents, human behavior in fire, etc. In other cases, the lessons are not new but are serious enough to highlight once again, with yet another fire tragedy report. In some cases, special reports are devel­oped to discuss events, drills, or new technologies which are of interest to the fire service.
  • The reports are sent to fire magazines and are distributed at National and Regional fire meetings. The International Association of Fire Chiefs assists the USFA in disseminating the findings throughout the fire service. On a continuing basis the reports are available on request from the USFA; announce­ments of their availability are published widely in fire journals and newsletters
  • This body of work provides detailed information on the nature of the fire problem for policymakers who must decide on allocations of resources between fire and other pressing problems, and within the fire service to improve codes and code enforcement, training, public fire education, building technology, and other related areas.
  • The Fire Administration, which has no regulatory authority, sends an experienced fire investigator into a community after a major incident only after having conferred with the local fire authorities to insure that the assistance and presence of the USFA would be supportive and would in no way interfere with any review of the incident they are themselves conducting. The intent is not to arrive during the event or even immediately after, but rather after the dust settles, so that a complete and objective review of all the important aspects of the incident can be made

Prince William County (VA) Fire Rescue Kyle Wilson LODD Report

  • The Prince William County (VA) Department of Fire and Rescue published a comprehensive line of duty death report for Technician I Kyle R. Wilson on Saturday, January 26, 2008. Technician I Wilson was the first line of duty death in the Department’s 41-year history. The Department is sharing the LODD Investigative Report to honor Kyle, and in an effort to reduce and prevent firefighter line of duty deaths at the local, region, state, and national levels.
  • Technician Kyle Robert Wilson was 24-years old and was born in Olney, Maryland. He grew up in Prince William County and graduated from Hylton High School and George Mason University. He was an avid baseball and softball player. Technician Wilson joined the Prince William County Department of Fire and Rescue on January 23, 2006. Technician Kyle Wilson died in the line of duty on April 16, 2007 while performing search and rescue operations at a house fire on Marsh Overlook Drive, located in the Woodbridge area of Prince William County. On that day, Technician Wilson was part of the firefighter staffing on Tower 512 which responded to the house fire that was dispatched at 0603 hours. The Prince William County area was under a high wind advisory as a nor’eastern storm moved through the area. Sustained winds of 25 mph with gusts up to 48 mph were prevalent in the area at the time of the fire dispatch to Marsh Overlook Drive.
  • Initial arriving units reported heavy fire on the exterior of two sides of the single family house and crews suspected that the occupants were still inside the house sleeping because of the early morning hour. A search of the upstairs bedroom commenced for the possible victims. A rapid and catastrophic change of fire and smoke conditions occurred in the interior of the house within minutes of Tower 512’s crew entering the structure.
  • Technician Wilson became trapped and was unable to locate an immediate exit out of the hostile environment. Mayday radio transmissions were made by crews and by Technician Kyle Wilson of the life-threatening situation. Valiant and repeated rescue attempts to locate and remove Technician Wilson were made by the firefighting crews during extreme fire, heat and smoke conditions. Firefighters were forced from the structure as the house began to collapse on them and intense fire, heat and smoke conditions developed. Technician Wilson succumbed to the fire and the cause of death was reported by the medical examiner to be thermal and inhalation injuries.
  • The Department of Fire and Rescue immediately formed a multi-dimensional investigation team following the incident. The investigation team was comprised of five Department of Fire and Rescue uniform personnel and two external members from area fire departments. For eight months, the team thoroughly examined the events that occurred at the Marsh Overlook fire incident and identify the factors involved with the line of duty death of Technician I Kyle Wilson. The resulting report represents thousands of hours of effort to analyze fire and rescue operations and is a factual representation of the events that occurred. The report also provides a frame work for organizational level improvements.
  • The major factors in the line of duty death of Technician I Wilson were determined to be:
    • The initial arriving fire suppression force size.
    • The size up of fire development and spread.
    • The impact of high winds on fire development and spread.
    • The large structure size and lightweight construction and materials.
    • The rapid intervention and firefighter rescue efforts.
    • The incident control and management.
    • The Marsh Overlook fire incident was an immense fire fueled by extremely flammable building material products and a vicious wind. It was an environment where information gathering and decision making had to be performed in the time measurement of seconds. During the chain of events that occurred and under severe circumstances, fire and rescue personnel performed at exceptional levels.
  • During the repeated attempts to reach and rescue Technician I Wilson, personnel displayed heroic efforts and jeopardized their own safety. The Department will never forget the sacrifice that Technician Wilson made in an attempt to ensure others were safe. By sharing the knowledge gained from this very tragic and painful incident, the Department will ensure his sacrifice was not in vain and hope that other fire and rescue departments can avoid another similar occurrence.

Worcester (MA) Fire Cold Storage Fire LODD Report; Abandoned Cold Storage Warehouse Multi-Firefighter Fatality Fire 1999, Worcester, Massachusetts

  • A technical review of the 1999 Worcester, MA fire that claimed six firefighters concludes that abandoned buildings are a serious threat to firefighters and fire departments must make a concerted effort to use technology to maintain data on buildings in their response districts.
  • 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.
  • Eleven minutes into the fire, the owner of the abutting Kenmore Diner advised fire operations of two homeless people who might be living in the warehouse. The rescue company, having divided into two crews, started a building search. Some 22 minutes later the rescue crew searching down from the roof became lost in the vast dark spaces of the fifth floor. They were running low on air and called for help. Interior conditions were deteriorating rapidly despite efforts to extinguish the blaze, and visibility was nearly lost on the upper floors. Investigators have placed these two firefighters over 150 feet from the only available exit.
  • An extensive search was conducted by Worcester Fire crews through the third and fourth alarms. Suppression efforts continued to be ineffective against huge volumes of petroleum based materials, and ultimately two more crews became disoriented on the upper floors and were unable to escape. When the evacuation order was given one hour and forty-five minutes into the event, five firefighters and one officer were missing. None survived.
  • A subsequent exterior attack was set up and lasted for over 20 hours utilizing aerial pieces and del­uge guns from Worcester and neighboring departments. Task force groups from across the State of Massachusetts responded to initial suppression and subsequent recovery efforts. During this time, the four upper floors collapsed onto the second which became known as “the deck”. Over 6 million gallons of water were used during the suppression efforts. According to NFPA records, this is the first loss of six firefighters in a structure fire where neither building collapse nor an explosion was a contributing factor to the fatalities.

Field Trips

  • Take a good look at the structures, occupancies and  buildings in you first, second and third due areas, look around your community and jurisdiction as well as your mutual aid and greater alarm response box areas.
  • Have you stopped for a minute today and taken a good look around? Whether you’re sitting in the front seat at the stop light of an intersection or as you’re peering out the side cab window coming back from an alarm or while running errands in your POV; have you taken a good look around? As the Springsteen song goes; “this is your town”.
  • There’s a lot that can be gleaned from your surroundings on any given day. We sometimes take for granted the subtle changes that are happening all around us as we take care of business on our rounds, runs and calls. We tend to focus in on the immediacy of the events that are happening in front of us that demand our attention but fail to take a look around to pick up on information, data and insights that can help us on that next run or down the road in the future.
  • Take a look at the construction that might be going up in your areas. I’m certain you’re paying close attention to what’s happening in your first-due, but what about that third-due area, that neighboring jurisdiction or the mutual-aid area that you occasionally run in to? When you’re on that next EMS run or an investigation of an odor or alarm bells service call, take a few extra minutes to walk through the occupancy. Conduct your own mini company level pre-plan.
  • Look at the layout, features, access and construction features. If you have a chance, verify the structural support systems employed by the building for the floor and roof systems. If you have time, take the company on a quick site visit to that building that’s under construction or the renovations that are again underway in that commercial or business occupancy around the corner from quarters.
  • These continuing challenging economic times places a great deal of influence on what’s being built, how it might be constructed, the manner in which a building may be operational one day, vacant the other and under renovation the next. Sometimes these transformations occur literally overnight.
  • Take a good look around, this is your town…your district, your response area. Know your buildings, understand their performance profiles, and assess the predictability of performance. Remember; Building Knowledge = Firefighter Safety.

Building Construction

I continue to suggest that it’s no longer just brute force and sheer physical determination that define structural fire suppression operations, although any seasoned firefighter and company officer knows that at times; it is what gets the job done under the most arduous and demanding of circumstances. However, from a methodical and disciplined perspective, aggressive firefighting must be redefined and aligned to the built environment and associated with goal oriented tactical operations that are defined by risk assessed and analyzed tasks that are executed under battle plans that promote the best in safety practices and survivability within know hostile structural fire environments.

We can still meet the demands of the job, as firefighters; but do it with Tactical Patience and not at the expense of Command Compression and Tactical Entertainment or worst Operational Recklessness.

The traditional attitudes and beliefs of equating aggressive firefighting operations in all occupancy types coupled with the correlating, established and pragmatic operational strategies and tactics must be adjusted and modified to include intelligent risk assessment, calculated risk analysis, safety and survivability profiling, and strategic operational and tactical value. The demands and requirements of modern firefighting will continue to require the placement of personnel within situations and buildings that carry risk, uncertainty and inherent danger. As a result, risk management must become fluid and integrated with intelligent tactical deployments and operations recognizing the risk problematically and not fatalistically, resulting in safety conscious strategies and tactics. We need to think about the Predicative Strategic Process, refined Tactical Deployment Models integrating intelligent Structural Anatomy and Predictive Occupancy Profiling.

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 adjusted and enhanced to address these new rules of structural fire engagement. There is a profound need to gain 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. Its all about the new formula….Bk=F2S.

Additionally, think about the following

  • Don’t Treat Your Buildings and Occupancies the Same anymore
  • Increase Situational Awareness
  • Increase Your Competencies
  • Know Your Buildings
  • Be aware of Command Compression
  • Implement Tactical Patience
  • Tactical Entertainment
  • Building Knowledge = Firefighter Safety
  • Fire Behavior & Fire Dynamics
  • Situational Awareness
  • Naturalistic Decision Making

NIOSH Suggested Truss Placard Type
EXAMPLE LANGUAGE FOR A LAW REQUIRING LABELING OF BUILDINGS FOR THE FIRE SERVICE
This sample language is based on recommendations in the National Institute for Occupational Safety and Health (NIOSH) report entitled “NIOSH Alert: Preventing Injuries and Deaths of Firefighters due to Truss System Failures.”
The report states: “Consider placing building construction information outside the building. Include
information about roof and floor type.

The NIOSH report also recommends as part of pre-fire planning to: Record data regarding roof and floor construction (e.g., wooden joist, wood truss, steel joist, steel truss, beam and girder, etc.) [NFPA 2003]. The sample language below provides building labeling that identifies the building’s construction type, is simple yet logical, and should allow firefighters to quickly know the building’s floor and roof construction materials, promoting better and more complete information on the fireground and increased firefighter safety.

xxx Identification of structural construction. Structural construction types shall be identified by a sign or signs, in accordance with the provisions of this section.

xxx.1 Signs. Signs shall be affixed where a building or a portion thereof is classified as Group A, B, E, F, H, I, M, R-1, R-2, R-4 or S occupancy. The owner of the building shall be responsible for the installation of the sign.
xxx.2 New buildings and buildings being added to. Signs shall be provided in newly constructed buildings and in existing buildings where an addition that extends or increases the floor area of the building.

State of Florida, Truss Placard System 2008;
The Aldridge-Benge Firefighter Safety Act. The law was named in honor of Orange County firefighters Todd Aldridge and Mark Benge, who died in 1989 after the truss roof of a gift shop collapsed. Under the new law, owners of any commercial, industrial or multi unit residential structure, have to clearly mark if their buildings have lightweight roof or floor trusses, allowing firefighters to change their tactics when working in these types of structures

633.027 Buildings with light-frame truss-type construction; notice requirements; enforcement
(1) The owner of any commercial or industrial structure, or any multiunit residential structure of three units or more, that uses light-frame truss-type construction shall mark the structure with a sign or symbol approved by the State Fire Marshal in a manner sufficient to warn persons conducting fire control and other emergency operations of the existence of light-frame truss-type construction in the structure.
(2) The State Fire Marshal shall adopt rules necessary to implement the provisions of this section, including, but not limited to:
(a) The dimensions and color of such sign or symbol.
(b) The time within which commercial, industrial, and multiunit residential structures that use light-frame truss-type construction shall be marked as required by this section.
(c) The location on each commercial, industrial, and multiunit residential structure that uses light-frame truss-type construction where such sign or symbol must be posted.
(3) The State Fire Marshal, and local fire officials in accordance with s. 633.121, shall enforce the provisions of this section. Any owner who fails to comply with the requirements of this section is subject to penalties as provided in s. 633.161.

CITY OF CHESAPEAKE, VA TRUSS ID PROGRAM; A designated sticker is used for quick recognition of potential Collapse Dangers associated with TRUSS constructed buildings. The sticker is placed on every entry door of all commercial buildings with Truss construction. The use of trusses in building construction presents a great danger to firefighting personnel when those structures are involved in fire conditions. By design, the truss members in floor and roof assemblies will collapse, without warning, after being exposed to heat or flame contact for a very short period of time. Because of the inherent danger firefighters must face while operating within these buildings, a Truss Identification Program (TIP) has been instituted to alert personnel of the danger prior to beginning fire suppression operations. The Truss Identification Program is intended to alert the members of the Chesapeake Fire Department with pertinent pre-plan information before firefighting forces are committed to an interior attack.

The TIP shall be an ongoing program applied to all commercial buildings inspected by the Chesapeake Fire Department.

City of Greencastle, Indiana

The City of Greencastle, Indiana and the Greencastle Fire Department recently enacted and approved an Engineered Lumber ID Program consisting of a sticker that is used for quick recognization of potential Collapse Dangers associated with Engineered Lumber constructed buildings. The sticker is placed on every electrical meter of all residential & commercial buildings with Engineered Lumber construction built after May 13th 2008. The news release states that; the use of this type of lumber in building construction presents a great danger to firefighting personnel when those structures are involved in fire conditions. By design, the Engineered Lumber in floor and roof assemblies will collapse, without warning, after being exposed to heat or flame contact for a very short period of time. Because of the inherent danger firefighters must face while operating within these buildings, an Engineered Lumber Identification Program (ELIP) has been instituted to alert personnel of the danger prior to beginning fire suppression operations.

The Engineered Lumber Identification Program is intended to alert the members of the Greencastle Fire Department with pertinent pre-plan information before firefighting forces are committed to an interior attack. The sticker is unobtrusive and is placed directly on a meter box, for example, and alerts the FD if either the floor joists and/or the trusses are made of and Engineered Lumber System and materials. The fire officers are already checking the utility boxes on all fires as part of their initial size-up. The ELIP shall be an ongoing program applied to all residential & commercial buildings inspected by the Greencastle Fire Department.

ORDINANCE 2008 – 4 states; AN ORDINANCE REQUIRING A REFLECTIVE SYMBOL ON STRUCTURES USING ENGINEERED LUMBER
WHEREAS, many new building structures currently use engineered lumber in their construction;
WHEREAS, some types of engineered lumber burn at a rate faster that other types of lumber; and
WHEREAS, in fighting fires, it would be helpful to know the types of materials used in the construction of a structure.

NOW THEREFORE be it ordained by the Common Council of the City of Greencastle as follows:
1. Definitions:
a. Engineered Lumber shall mean prefabricated I-joists, truss joists, and truss rafters, and laminated beams and studs.
b. Structure shall mean primary, secondary and accessory structures as defined in the Greencastle Zoning Code that have electrical meters that serve the structure.

2. All structures constructed with engineered lumber after the effective date of this ordinance must have a reflective symbol affixed to each electrical meter serving the structure.

3. The reflective symbol shall be in the form of a sticker, issued by the City of Greencastle that states that the structure is constructed with engineered lumber

4. Any person violating this ordinance by refusing to use the reflective symbol or by removing the reflective symbol shall be subject to a fine in an amount of $25.00 per violation. Each day that a violation occurs shall constitute a separate violation, subject to a separate fine.

5. The owner of any structure that was constructed with engineered lumber prior to the effective date of this ordinance is requested to place the reflective symbol on the electrical meter serving the structure on a voluntary basis.

This is another great example how local level insights, actions and legislation can go a long way in supporting fire service operational challanges as they relate to building construction systems, methodologies and materials. Remember, We can certainly work diligently AND cooperativley with local government officials to enhance incident operations and make our jobs safety, one step at a time….
