Vacant Structure Fire-Three Alarm, Type III Construction

Identifying, Establishing and Managing Collapse Zones

I mentioned in a recent post about on-going research and recommendations being developed for a significant report.

A notable issue that seems to resonate and surface on a reoccurring bais is the identification, establishment and management of collapse zones.
Building type, construction systems and materials, initiating, apparent or contributIng factors have an influence on collapse zone management (CZM).
Perimeter wall compromise and collapse of Type III and IV buildings continue to represent the leading types of collapse that contribute to significant firefighter injuries and line of duty deaths.
 
The ability to Read the Building, identify obvious and subtle features, conditions and indicators leading to collapse or compromise or the management and control of post collapse conditions is imperative.
 
Another critical operational factor is managing collapse zones and restricting access with consideration for degraded building conditions and the potential for multiple secondary collapse.
  • Are you up to speed with criteria for recognizing pre and post collapse indicators?
  • Do you have SOP/SOGs for collapse OPS?
 Collapse Zones
At a minimum:
Establish and maintain at a minimim a perimeter Collapse Management Zone (CMZ) of 1.5 x the building height.

Based on building type, height, materials of construction and type of projected collapse type – the potential for materials to travel beyond the CMZ is probable and should be assessed.

Safety Officers MUST maintain control to restrict access and to ensure companies are aware of potential for secondary collapse of compromised building features, assemblies or materials.

Maintain an acute high level of Situational Awareness, know your surroundings and don’t get tunnel vision on your task assignment.

The 1942 Luongo’s Restaurant Fire and Collapse in East Boston; Six Boston Firefighter Line of Duty Deaths

Boston Fire Department Box 6153 Five Alarm November 15,1942

 

Boston Fire Department Box 6153 Five Alarm November 15,1942

A multiple alarm fire and collapse 70 years ago resulting in six Boston Firefighter LODDs was overshadowed by the Coconut Grove Fire which occurred 13 days later. Here’ the story and legacy.  

 The 1942 Luongo’s Restaurant Fire and Collapse in East Boston; Six Boston Firefighter Line of Duty Deaths

During the early morning hours of Sunday November 15, 1942, a still alarm followed by box alarm 6153 was received for a fire at 4-6 Henry Street located in the Old Armory Building at Maverick Square in East Boston (MA). The address was for a report of fire in the Luongo’s Restaurant. A fire broke out in the rear of Luongo’s Restaurant on the first floor at about 2:26 a.m. The Boston Fire- District #1 report stated the fire originated in the rear kitchen ceiling.

November 16, 1942 New York Times:

The following is a description of the fire from the November 16, 1942 New York Times: “The fire, starting from a fireless cooker in the cafe on the ground floor at Henry Street and Maverick Square, suddenly swept through the building.

The firemen who were killed had just entered a restaurant on the second floor with a line of hose. As the flames ate through the cross timbers the wall collapsed with a roar, burying two men on the stairs and crushing the three others manning the hose.  That part of the wall which fell outward felled about forty firemen standing on the Henry Street side of the building beside the new $20,000 ladder truck, which was buried under the wreckage. At the same, a hot air explosion blew a half dozen firemen across Henry Street.”

The Building

The Luongo’s Restaurant was housed in what was called the Armory Building a five and one half story Type III Building of ordinary construction (Brick and joist) consisting of masonry bearing walls with approximate dimensions of 35 feet width x 60 feet depth x 65 foot height. The ensuing fire would spread to the exposure building at 10 Henry Street a three story 20 ft. X 40 ft. x 40 ft type III (brick and joist) structure.

Fire and Collapse

Upon arrival of the first alarm companies, the fire initially was commanded by Fire Captain Amsler, Ladder Co. 2. District Chief Crowley rapidly assumed command upon his arrival and directed initial fire suppression activities of the companies to interior operations and quickly ordered a second alarm at 03:04hours.

Command was subsequently transferred to Deputy Chief Louis Stickel who ordered a third alarm struck due to fire extension twenty minutes later.

Suppression, ventilation and rescue operations were conducted with the fire under control when at 04:15 hours with without warning, it was reported the 3rd, 4th and 5th floors began to collapse with the brick masonry wall on the Henry Street side collapsing outward into the street. Ladder Company 8, a new 125 ft. aerial ladder, the largest in the United States at the time was buried in the timber and brick rubble and collapse pile. It was reported that as many of 43 firefighters in the street were injured as a result of the collapse.

 

Search, Rescue and Recovery Efforts

 

The arrival of Chief of Department Samuel Pope ordered fourth and fifth alarms. This brought Engine Companies 40, 9, 5, 11, 50, 8, 32, 6, 39, 3, 33, 12, 13, 38, 21, 35, 37, 20, 16, 10, 42, 51, 19; Ladder Companies 2, 31, 21, 8 and 3.

  • First Alarm: 02:27 hrs.
  • Second Alarm: 03:05 hrs.
  • Third Alarm: 03:24 hrs.
  • Fourth Alarm: 04:20 hrs.
  • Fifth Alarm: 04:35 hrs.

With both extensive interior and exterior collapse conditions with numerous trapped and injured firefighters, rescue efforts and medical assistance was being rendered by all fire service, military, hospital and civilian resources. Local Coast Guardsman were deployed to support the massive search and rescue efforts.

 

Rescue and Recovery

Six Boston Firefighters were killed in the line of duty as a result of the collapse, all of whom were conducting operations and working on the second floor with hose lines.

 Post Requiem

The Department’s 125 foot “jinx” aerial ladder, reported to be the largest in the nation at that time, was standing beside the falling wall on Henry Street. It was buried in the wreckage. The ladder was originally purchased by the City of Somerville. They found upon delivery that it was too big for their firehouse. Boston bought it. The truck had a series of problems. (additional Story on the 1941 American La France 125′ metal aerial By William Noonan,   HERE)  Apparatus Info – See Bostonfirehistory.org HERE

There was some speculation that due to the long ladder and wide bed, the large ladder might have caused the wall collapse. This theory was later ruled out. In fact, some of the firefighters who were on the ladder at the time of the collapse, credit the ladder bed with saving their lives. When the granite and debris began falling, they lay down in the bed and the rubble slid down over them to the street.

Many felt that this was the end to the ladder. But, it was repaired and returned to service in South Boston as Ladder 19. Tragedy would continue to haunt this piece of apparatus. On December 3, 1947, Ladder 19 was out of service conducting tests on its brakes when it overturned and rolled. Provisional Firefighter Joseph B. Sullivan, on the job for less than six months, was killed. The Department took the truck out of service and scrapped

Individuals Remembered

As with many of these incidents, the men involved came from different backgrounds and circumstances that put them on that second floor that fateful night.

Edward Macomber was the father of eight children and considered to be one of the best firefighters in the department according to his superior officers. He was a member of the department for 28 years, and had been injured while on duty more than seven times.

Francis Degan, at age 24 was one of the youngest members of the Boston Fire Department at the time. He had been on the job only 19 months prior to November 15th. His officers thought that the young fireman was well on his way to becoming an officer. Young Degan took great pride in being a firefighter and realized his life’s ambition when he was appointed to the department to follow in the footsteps of his father, who was attached to Ladder Company 1.

John Foley, a hoseman on Engine Company 3, had been a member of the department for more than 30 years. He was planning to retire in a short time. In a tragic case of irony , Firefighter Foley should have been on a day off at the time of the fire, but had changed his schedule in order to get some time off later.

World War 1 veteran Pete McMorrow was a bachelor member of Engine Company 50 and was loved by many of the school children of Charlestown. He had served in the Navy in the first war and was telling his closest pals that he might just be going back to serve again. At age 46, he had carried the colors of the Boston Fireman’s Post #94, American Legion, through downtown Boston. While trapped in the debris for eleven hours, McMorrow’s fellow company members crawled into the space where he lay to tell him to hang on and they’d get him out soon. Throughout the early morning and into the next day the rescue efforts continued. However, when they were finally able to get to McMorrow, it was too late.

This fire and the subsequent six firefighter line of duty deaths were overshadowed by the Cocoanut Grove Fire which occurred only 13 days later on November 28, 1942.

Memorial, Dedication, and Reception

On Thursday November 15, 2012 the East Boston Neighborhood Health Center and the Boston Fire Department will be conducting a Memorial, Dedication, and Reception in Recognition of the 70th Anniversary of the Luongo Fire at Maverick Square, East Boston.

The event is scheduled from 12:00 pm to 2:00 pm at 20 Maverick Square, Boston, MA.

 

Video: Former Boston Fire Commissioner Paul Christian shares the story of the little-known Luongo fire as well as that of the 8-alarm Thanksgiving Day Fire of 1889. November has been a tragic month in Boston’s fire history. On November 15, 1942, a fire started in the back room of the Luongo Restaurant.

  Historical Note: Three and a half story high, with granite faced and brick exterior walls, the interior wooden joisted building at the corner of Henry Street and Maverick Square in 1942 was one of the oldest buildings in East Boston. It was typical of mid 19th century Boston commercial construction. In accounts of the fire it is frequently referred to as “Old Armory Hall”. “Armory Hall” is the name by which it was known in the early years of the 20th century. That building however never was actually an armory as such. There once was an armory in East Boston. It was located at the corner of Maverick and Bremen Streets in a wooden building that preceded the still standing brick Overseers of the Public Welfare Building. The building in which the “Luongo Fire” occurred was built sometime before 1858. It was known originally as “Ritchie Hall” likely from the name of its owner.

Fire Fighter Killed by Exterior Wall Collapse during Defensive Operations at a Commercial Structure

No comments

On June 17, 2011, a 22-year-old male paid-on-call fire fighter received fatal injuries when he was struck by bricks and falling debris during an exterior wall collapse at a commercial structure fire.

Crews worked using defensive operations for about 45 minutes attempting to extinguish the fire in the 96 year-old brick and masonry structure that housed an antique store with living quarters located in a rear addition. The victim and another fire fighter were moving a 35-foot aluminum ground ladder away from the Side D (east) wall of the structure when the top part of the exterior wall collapsed. No other fire fighters were injured in the collapse.

NIOSH REPORT: Report 2011-15     HERE

Contributing Factors

  • 96 year-old brick masonry structure degraded by fire burning for over 45 minutes
  • Fire fighters with limited experience entered collapse zone to move ground ladder
  • Entering collapse zone in close proximity to master stream directed onto roof
  • Limited visibility at side and rear of structure may have obscured signs of pending collapse
  • Limited training on structure collapse hazards.

 

Key Recommendations

  • Establish and monitor a collapse zone when conditions indicate the potential for structural collapse
  • Train all fire fighting personnel on the risks and hazards related to structural collapse
  • Train on and understand the effects of master streams on structural degradation
  • Conduct regular mutual aid training with neighboring departments
  • Designate a staging area for all unassigned fire fighters and apparatus
  • Implement national fire fighter and fire officer training standards and requirements.

Fire Behavior

According to the investigating State Fire Marshal, the fire originated in the rear of structure due to undetermined causes. A thunderstorm had passed through the area approximately two hours before the fire was reported and lightning strikes were reported in the immediate area. The dispatch center received multiple phone calls reporting a fire behind the antique store near the courthouse square.

Indicators of significant fire behavior

  • Smoke filled store front when first crews arrived
  • Smoke pushing out cracks in the Side A and D walls and around windows on Side D
  • Thickening dark brown smoke upon arrival
  • No visible fire
  • Windows at front broken to vent structure
  • Windows on Side D broken to vent 2nd floor
  • Roll up overhead door opened at C/D corner
  • Fire rapidly grew and moved toward front of store, becoming visible through windows
  • Smoke diminished and visibility improved at front
  • Smoke continued to push out under pressure through cracks in Side A and D walls
  • Fire vented through roof at rear of structure
  • Thick column of turbulent dark grey-black smoke rose above structure
  • Smoke increased in front and Side D of structure as fire intensified
  • Smoke continued to push out cracks on Side A and D walls
  • E-43 deck gun put into operation applying water to roof with 13/8-inch solid bore tip
  • Elevated master stream put into operation from D-110 aerial ladder (insufficient water supply resulted in insufficient fire flow)
  • E-43 deck gun re-directed hose stream to protect exposure buildings opposite Side D
  • Initial collapse of roof and walls at C/D corner
  • Partial wall collapse of Side D wall strikes fire fighter moving ground ladder.

Recommendations

Recommendation #1: Fire departments should establish and monitor a collapse zone when conditions indicate the potential for structural collapse.

Discussion: During fire operations, two rules exist about structural collapse: (1) the potential for structural failure always exists during and after a fire, and (2) a collapse danger zone must be established.4-9 A collapse zone is an area around and away from a structure in which debris might land if a structure fails. The collapse zone area should be equal to the height of the building plus an additional allowance for debris scatter and at a minimum should be at least 1½ times the height of the building.

Buildings can collapse due to the structural damage directly caused by a fire, or the activities of fire fighting operations. A fire department’s familiarity with types of construction in their community is an important tool in safely fighting fires. Once a collapse zone is established, fire departments should enforce a “no re-entry” policy unless approved by the Incident Commander.

Fire fighters need to recognize the dangers of operating near parapet walls or underneath overhanging awnings, porches, and other areas susceptible to collapse. Immediate safety precautions must be taken if factors indicate the potential for a building collapse. An external load, such as a parapet wall, steeple, overhanging porch, awning, sign, or large electrical service connections reacting on a wall weakened by fire conditions may cause a wall to collapse. Other factors include fuel loads, damage, renovation work, deterioration caused by the fire as well as pre-existing deterioration, support systems and truss construction.10-12 A collapse is a possibility after fire involvement of more than 10 minutes but fire departments should not rely solely on time as a collapse predictor.11

In this incident, the structure was estimated to be 22 feet high at the top of the D-side wall parapet wall so the collapse zone should have extended at least 33 feet from the structure, covering the entire width of the side-street adjacent to the structure. It is noted that fire fighters were instructed to stay away from the structure and a defensive strategy was used throughout the fire suppression operations. However, a collapse zone was never established or physically identified. Collapse zones can be physically marked by cones, caution tape and other types of physical barriers. Photo 10 taken at the incident scene showed fire fighters standing on the sidewalk as instructed opposite the wall that collapsed.

Recommendation #2: Fire departments should train all fire fighting personnel in the risks and hazards related to structural collapse.

Discussion: Proper training is an important aspect of safe fire ground operation. Both officers and fire fighters need to be aware of different types of building construction and their associated hazards.7, 9-10 For example, collapsing roof systems can exert pressure on supporting exterior walls, increasing the potential for wall collapse. Different roof systems may collapse at different rates.11 While heavy timber roof systems will withstand more degradation by fire than lightweight engineered roof trusses, both types are subject to failure.12 Different phases of the fire suppression activities, such as the initial attack, offensive, defensive, and overhaul phases will have different hazards. However, the potential for collapse exists in any fire-damaged structure.11 One source of information related to structural collapse hazards is the National Institute of Standards and Technology, Building and Fire Research Laboratory (NIST / BFRL). A DVD containing videos and reports related to structural collapse can be obtained from the NIST websiteExternal Web Site Icon http://www.bfrl.nist.gov/.13

Establishing priorities is another primary factor in safe fire ground operation that should be included in fire fighter training programs. The protection of life should be the highest goal of the fire service. According to retired Chief Vince Dunn, “When there is no clear danger to civilians, the first priority of firefighting should be the protection of fire fighters’ lives and when no other person’s life is in danger, the life of the fire fighter has a higher priority than fire containment or property consideration.”12 In this incident, there were no indications of civilians in danger inside the structure. It is noted that defensive operations were used throughout the incident.

The Illinois Fire Service Institute (IFSI) coordinates a statewide training program for individuals interested in becoming a fire fighter. This program offers a 24-hour Basic Fire Fighter course as well as Fire Fighter II and Fire Fighter III certification. The IFSI Fire Fighter II certification is roughly equivalent to the National Fire Protection Association (NFPA) Fire Fighter I and IFSI Fire Fighter III is roughly equivalent to NFPA Fire Fighter II as specified in NFPA 1001 Standard for Fire Fighter Professional Qualifications.1 NFPA FF I reflects minimum training standards for a fire fighter who is always working under supervision. NFPA FF II addresses the assumption of command and transfer of command but does not contain specific job performance requirements (JPRs) to illustrate the required skills. The IFSI 24-hour Basic Fire Fighter course may not properly prepare new fire fighters for the hazards associated with structural fire fighting. Many fire fighters, especially in the volunteer ranks, may be called upon to fill company officer and incident commander roles when they may not have received adequate training to prepare them for the additional responsibilities that are required of fireground officers. At a minimum, fire fighters who serve as company officers and who may be expected to serve as the initial incident commander should receive training equivalent to NFPA Fire Fighter II, as defined by NFPA 1001. In this incident, the victim had not completed the minimum IFSI or NFPA training requirements for individuals operating at a structure fire. Also, the two lieutenants who served as incident commanders had not completed training meeting the requirements of NFPA Fire Fighter II as defined by NFPA 1001, which should be the minimum training requirements for a fire fighter operating as a fireground officer.

Recommendation #3: Fire departments should train on and understand the effects of master streams on structural degradation.

Discussion: Master streams are an effective tool for fire suppression operations. Master streams can deliver a large volume of water over a distance while reducing the direct exposure of fire fighters to the fire. Master stream operations can also accelerate structural degradation and can increase the risk of a building collapse.14-16 When multiple master streams are flowing water into a building, the additional weight of the water can rapidly increase the potential for structural collapse. Water weighs 8.33 pounds per gallon. A master stream flowing 1,000 gallons per minute can add an additional 8,330 pounds per minute that the structure, already deteriorated by fire, must support. In 30 minutes, the additional weight contributed by this master stream could add 249,900 pounds or 125 tons of additional weight to the structure.17 Direct impingement of the master stream at close range can also directly contribute to structural degradation by dislodging bricks, breaking windows and other building components. Master streams can also push fire throughout the interior of a structure, leading to fire spread.

Another important indicator that fire fighters and officers should look for is the presence or lack of runoff during master stream operations. If multiple outside streams are being applied to a structure and there is little or no water runoff, the water must be accumulating somewhere.15 As noted above, the additional weight added by standing water on roofs or floors can significantly contribute to the risk of structural collapse. Fire fighters and fire officers need to understand this fact and take this into consideration as part of the Incident Action Plan. If a collapse zone has not already been established, one should be established now. Fire fighters should not be allowed to enter the collapse zone without the direct permission of the Incident Commander.18

Recommendation #4: Fire departments should use risk management principles at all structure fires.

Discussion: While it is recognized that fire fighting is an inherently hazardous occupation, established fire service risk management principles are based on the philosophy that greater risks will be assumed when there are lives to be saved and the level of acceptable risk to fire fighters is much lower when only property is at stake. Interior (inside a structure) offensive fire-fighting operations can increase the risk of traumatic injury and death to fire fighters from structural collapse, burns, and asphyxiation. Established risk management principles suggest that more caution should be exercised in abandoned, vacant, and unoccupied structures and in situations where there is no clear evidence indicating that people are trapped inside a structure and can be saved.19 More importantly, the fire department must establish a standardized method or approach to assess the risks encountered at each incident especially structure fires. Structure fires are very dynamic and fast paced operations with little room for error, mistakes, or miscalculations of the significance of the risk encountered.

The Incident Commander is specifically responsible for managing risk at the incident; however, one person cannot be expected to apply these principles to an incident if the organization has not integrated a standard approach to risk management into its standard operating procedures and its organizational culture. To be effective, risk management principles must be integrated into the entire operational approach of the fire department organization. They must be incorporated within the duties and responsibilities of every officer and member. The single most important reason to establish an effective incident management system is to ensure that operations are conducted safely. Every individual assigned to the incident is responsible for monitoring and evaluating risks and for keeping the Incident Commander informed of any factor that causes the system to become unbalanced. Continuous risk assessment should be reprocessed with every benchmark or task completed until the incident is ended.20

A standardized evaluation of the situation must occur at each incident starting with the first arriving officer or member of the department arriving on scene of the incident. This process starts with the scene size-up. This responsibility starts with the first arriving unit that must look at the entire incident scene versus focusing on a small part of the situation. During the size-up, the Incident Commander must remember the incident prioritizes which are:

  •             Life Safety
  •             Incident Stabilization
  •             Property Conservation
  •             Continuous – fire fighter safety

Situations where there is clear evidence or indication that there is a life safety (imminent rescue or trapped occupants) changes the focus of the strategy and incident action plan. Established risk management principles dictate that more caution is exercised in abandoned, vacant, and unoccupied structures.

Scene size-up should include the following information. Scene size-up should begin at the beginning of the alarm, continue upon arrival on scene, and continue throughout the incident. Some considerations should include:

  •             Life safety/occupied structure and realistic evaluation of occupant survivability and rescue potential
  •             Type of Occupancy and consideration of fire load and fire behavior
  •             Access
  •             Building Construction
  •             Environmental Conditions
  •             Location and extent of the fire within the building
  •             Resources Responding
  •             Water Supply
  •             Special Hazards/Risks
  •             Time of Day
  •             Color of Smoke
  •             Utilities
  •             Exposures affected or potential affected
  •             A realistic evaluation of the ability to conduct an offensive attack with available resources.19, 21

The Incident Commander should use the scene size-up to formulate a strategy and the Incident Action Plan. Incident factors and their possible consequences offer the basis for a standard incident management approach. Decisions and the action they produce can be no better than the information on which they are based. A standard information management approach is the launching pad for effective incident decision making and successful operational performance. The IC must develop the habit of using the critical factors in their order of importance as the basis for making the specific assignments that make up the Incident Action Plan (IAP). This standard approach becomes a huge help when it is hard to decide where to start.

The incident scene size-up must be viewed as a 2-part process: 1) determining the conditions of the incident scene, and 2) determining whether the fire department has on scene, has in route, or is in need of additional resources to address the challenge presented by what has been identified during the first part of the size-up process.

The IC must create a standard information system and use effective techniques to keep informed at the incident. Information is continually received and processed so that new decisions can be made and old decisions revised based on increased data and improved information. The IC can never assume action-oriented responders engaged in operational activities will just naturally stop what they are doing so they can feed the IC a continuous supply of top-grade objective information. It is the IC’s responsibility to do whatever is required to stay effectively informed.22

During most critical incident situations, Command many times must develop an IAP, based only on the critical factor evaluation information available at the beginning stage of operations. Many times, that information is incomplete. Even though the IC will continue to improve its quality, the IC will seldom function during the fast, active periods of the event with complete or totally accurate information on all factors.22

This is most evident during confused, compressed-time initial operations. This continual improvement in the accuracy and timeliness of incident information becomes a major IC function. The ability of the IC and the tactical and task level officers to quickly be informed and perform an analysis of the critical factors that can cause major physical and emotional setbacks to the responders and the customers will have a great impact on the health and longevity of the fire fighters, other first responders, the customers and their property.22

In general terms, the risk management plan must consider the following: (1) risk nothing for what is already lost—choose defensive operations; (2) extend limited risk in a calculated way to protect savable property—consider offensive operations; (3) and extend very calculated risk to protect savable lives—consider offensive operations.19, 23, 24 NFPA 1500 Standard on Fire Department Occupational Safety and Health Program, Chapter 8.3 addresses the use of risk management principles at emergency operations. Chapter 8.3.4 states that risk management principles shall be routinely employed by supervisory personnel at all levels of the incident management system to define the limits of acceptable and unacceptable positions and functions for all members at the incident scene. Chapter 8.3.5 states that at significant incidents and special operations incidents, the Incident Commander shall assign an incident safety officer who has the expertise to evaluate hazards and provide direction with respect to the overall safety of personnel. The annex to Chapter 8.3.5 contains additional information.25

This incident occurred in a structure of mixed occupancy of both commercial and residential use. First arriving crews talked to the building owner and verified that no one was inside the structure. The Incident Commander quickly adopted a defensive strategy and told fire fighters at the front door not to enter the structure. As additional resources arrived on-scene, and Command was passed to higher ranking officers, a defensive operation was maintained. A ground ladder used to ventilate the second story windows on the Side D was left in place where it was last used. Approximately 45 minutes after the first crews arrived on-scene, two fire fighters overheard discussions about the ladder being in a bad location and approached the structure to retrieve the ladder. Given the length of time the fire had been burning, the visual indicators of structural instability (smoke pushing out through cracks in the masonry walls and the sound of bricks popping), the presence of star-shaped anchor plates on the exterior wall and other factors, the best scenario would have been to leave the ladder in place until the area was deemed safe or just write the ladder off. A safer strategy for retrieving the ladder would have been to use a pike pole or other long tool to reach the ladder from a safe distance under the direct observation of other fire fighters monitoring the conditions of the exterior walls. Using a pike pole or other tool to pull the ladder down while standing as far as possible from the exterior wall, may have resulted in a different outcome.

Recommendation #5: Fire Departments should utilize the Incident Command System at all emergency incidents.

Discussion: National Fire Protection Association (NFPA) 1500 Standard on Fire Department Occupational Safety and Health Program, 2007 Edition25 and NFPA 1561 Standard on Emergency Services Incident Management System, 2008 Edition26, both state an incident management system should be utilized at all emergency incidents. Most often, this system is commonly known as or referred to as the Incident Command System (ICS).

The Incident Command System is intended to provide a standard approach to the management of emergency incidents. The many different and complex situations encountered by fire fighters require a considerable amount of judgment in the application of the Incident Command System. The primary objective is always to manage the incident, not to fully implement and utilize the Incident Command System. The Incident Commander should be able to apply the Incident Command System in a manner that supports effective and efficient management of the incident. The use of the Incident Command System should not create additional challenges for the Incident Commander, but rather provide a systems approach to ensuring for a successful outcome of the incident.26

Most incidents are considered routine and involve a small commitment of resources, while few incidents involve large commitments of resources, complex situations, and are low frequency/high risk events. It is imperative that the Incident Command System be able to accommodate all types and sizes of incidents and to provide for a regular process of escalation from the arrival of the first responding resources at a routine incident to the appropriate response for the largest and most complex incidents. The Incident Command System should be applied, even to routine incidents, to allow fire fighters and other first responders to be familiar with the system, prepared for escalation, and aware of the risks that exist at all incidents.26

NFPA 1561, Chapter 3.3.29 defines an incident management system as “A system that defines the roles and responsibilities to be assumed by responders and the standard operating procedures to be used in the management and direction of emergency incidents and other functions.”26 Chapter 4.1 states “The incident management system shall provide structure and coordination to the management of emergency incident operations to provide for the safety and health of emergency services organization (ESO) responders and other persons involved in those activities.”26 Chapter 4.2 states “The incident management system shall integrate risk management into the regular functions of incident command.” 26

The incident management system covers more than just fireground operations. The incident management system must ensure for command and fire fighter safety which includes situational evaluation, strategy and the incident action plan, personnel accountability, risk assessment and continuous evaluation, communications, rapid intervention crews (RIC), roles and responsibilities of the Incident Safety Officer (ISO), and interoperability with multiple agencies (law enforcement, emergency medical services, state and federal government agencies and officials, etc.) and surrounding jurisdictions (automatic aid or mutual aid responders).

One of the most critical components of this system is the development and implementation of an Incident Action Plan (IAP). For the fire service, the majority of times the Incident Action Plan is communicated verbally. The IAP is based on the resources immediately available and those responding. The goal is determined in accordance with the incident priority from which a strategy must emerge; tactical objectives, aimed at meeting the strategy, are determined and specific assignments made. A personnel accountability system should be established as assignments are made. The important point is that the Incident Commander communicates the IAP to tactical and task level supervisors.

Recommendation #6: Fire departments should designate a staging area for all unassigned fire fighters and apparatus.

Discussion: NFPA 1561 Standard on Emergency Services Incident Management System defines staging as a specific emergency management function where resources are assembled in an area at or near the incident scene to await instructions or assignments.26 Staging provides a standard controlled method to keep reserves of responders, apparatus, and other resources ready for action at the scene of the incident or close to the scene of the incident (within two – three minute response times). Staging also provides a standard method to control and record the arrival of apparatus and resources.

When the Incident Commander requests additional resources for an incident, the IC is responsible for designating a staging area. Depending on the size and complexity of an incident, multiple staging areas may be used. This is based on the response route of the resources, to stage resources by typing (e.g. engines, brush trucks, medic units, law enforcement, etc.), or due to location near the incident. The staging area manager documents the available resources. This helps the Incident Commander to keep track of the resources that are on the scene and available for assignment, and to know where they are located and where specific units have been assigned. The Staging Area Manager reports to the IC unless an Operations Section Chief has been assigned, then the Staging Area Manager would report to the Operations Section Chief.

When companies or resources arrive in staging, they report to the Staging Area Manager and stand by for assignment. The Staging Area Manager records and keeps an inventory of all resources and equipment assigned to Staging. A system needs to be in place that details what needs to occur when Staging starts to run low on resources. Staging lets “Command” know when resources are low, and Command orders more resources through Dispatch.

Staging provides an avenue for reducing overall incident communications, and maintaining control of resources throughout the incident operations.

Recommendation #7: Fire departments should conduct pre-incident planning inspections of buildings within their jurisdictions to facilitate development of safe fireground strategies and tactics.

Discussion: National Fire Protection Association (NFPA) 1620 Standard for Pre-Incident Planning, 2010 Edition, states “the pre-incident plan shall provide critical information for responding personnel at the time of dispatch and shall include initial actions based on the priorities of life safety, scene stabilization, and incident mitigation.” This standard also states that “the primary purpose of a pre-incident plan is to help responding personnel effectively manage emergencies with available resources. Pre-incident planning involves evaluating the protection systems, building construction, contents, and operating procedures that can impact emergency operations.”27 A pre-incident plan identifies deviations from normal operations and can be complex and formal, or simply a notation about a particular problem such as the presence of flammable liquids, explosive hazards, modifications to structural building components, or structural damage from a previous fire.7, 27-28

In addition, NFPA 1620 outlines the steps involved in developing, maintaining, and using a preincident plan by breaking the incident down into pre-, during- and post-incident phases. In the preincident phase, for example, it covers factors such as physical elements and site considerations, occupant considerations, protection systems and water supplies, hydrant locations, and special hazard considerations. Building characteristics including type of construction, materials used, occupancy, fuel load, roof and floor design, and unusual or distinguishing characteristics should be recorded, shared with other departments who provide mutual aid, and if possible, entered into the dispatcher’s computer so that the information is readily available if an incident is reported at the noted address. Since many fire departments have tens and hundreds of thousands of structures within their jurisdiction, making it impossible to pre-plan them all, priority should be given to those having elevated or unusual fire hazards and life safety considerations.

Pre-plan information should include predicted alarm assignments based upon the fire potential. This will help to ensure that needed resources are dispatched immediately, even if they are some distance away or will provided through mutual aid. If the expected fire potential dictates that 30 fire fighters are needed and the authority having jurisdiction only has 15 fire fighters, the pre-plan should identify the mutual aid resources available to safely and effectively mitigate the expected fire scenario. The pre-plan information should take into consideration the need for incident command and command level officers to fill roles such as safety officer, accountability, tactical level management (i.e. division or group supervisor), RIT / RIC supervision, staging, rehabilitation, IC support ( chief’s aide or staff assistant to monitor radio communications, track crew assignments, resources availability, etc.) and other functions as necessary. When the need for these positions are considered in the pre-planning process, these positions can be rapidly filled throughout the initial alarm assignments, allowing for crew and supervisory integrity while placing more experienced command level support officers in the roles needed to ensure effective supervision and support in the hazard zone. In this incident, pre-planning the structure could have identified the potential collapse hazards associated with the structure due to the age and type of construction, the presence of the star-shaped anchor plates on the exterior walls, and the high fuel load present. It is noted that the Fire Department A had an unwritten policy that any fires in the older commercial structures within the city would be fought defensively.

Recommendation #8: Fire departments should conduct regular mutual aid training with neighboring departments.

Discussion: Although there is no evidence that the following recommendation would have prevented this fatality, it is being provided as a reminder of a good safety practice. Mutual aid companies should train together and not wait until an incident occurs to attempt to integrate the participating departments into a functional team. Differences in equipment and procedures need to be identified and resolved before an emergency occurs when lives may be at stake. Procedures and protocols that are jointly developed, and have the support of the majority of participating departments, will greatly enhance overall safety and efficiency on the fireground. Once methods and procedures are agreed upon, training protocols must be developed and joint-training sessions conducted to relay appropriate information to all affected department members.

Fire departments should develop and establish good working relationships with surrounding departments so that reciprocal assistance and mutual aid is readily available when emergency situations escalate beyond response capabilities. Both fire departments involved in this incident were participating members in the Mutual Aid Box Alarm System (MABAS), a mutual aid system designated to assist with mutual aid response of fire, emergency medical services (EMS), specialized response teams, and station coverage during a state declared disaster or when an incident overwhelms the available resources of a participating community. This incident did not escalate to the size of a MABAS event. Both departments reported that they planned to implement mutual aid training with neighboring departments but had done so on a limited basis up to the time that this incident occurred.

Recommendation # 9: Fire departments should ensure that fire fighters wear a full array of turnout clothing and personal protective equipment (i.e. SCBA and PASS device) appropriate for the assigned task while participating in fire suppression and overhaul activities.

Discussion: Although there is no evidence that the following recommendation would have prevented this fatality, it is being provided as a reminder of a good safety practice. The proper selection and use of personal protective equipment (PPE) is required by OSHA regulations, recommended in NFPA standards, and is good safety practice. Chapter 7.1.1 of NFPA 1500, Fire Department Safety and Health Program, 2007 Edition, states “the fire department shall provide each member with protective clothing and protective equipment that is designed to provide protection from the hazards to which the member is likely to be exposed and is suitable for the tasks that the member is expected to perform.” Chapter 7.1.2. states “protective clothing and protective equipment shall be used whenever a member is exposed or potentially exposed to the hazards for which the protective clothing (and equipment) is provided.”25 The incident commander should establish the level of protective clothing necessary to enter the fire zones (hot, warm, and cold). The OSHA Respirator Standard Title 29, Code of Federal Regulations (CFR) 1910.134 lists requirements for SCBA use in immediately dangerous to life or health (IDLH) atmospheres.29 While the lack of personal protective equipment (PPE) and clothing did not contribute to the fatality that occurred at this incident, it is generally recognized that SCBA should be worn and used at all times when fire fighters may be exposed to smoke and other hazardous atmospheres. Photos taken during the incident show fire fighters working in close proximity to the burning structure who were not wearing proper respiratory protection (see Photo 7, Photo 8 and Photo 11).

In addition, standard setting organizations, national fire service organizations and other interested parties should:

Recommendation #10: Implement national fire fighter and fire officer training standards and requirements.

Discussion: In 2008, the National Volunteer Fire Council (NVFC) adopted a policy position that all volunteer fire departments should establish a goal to train all personnel to a level consistent with the mission of the fire department, based on the job performance requirements outlined in NFPA 1001: Standard for Fire Fighter Professional Qualifications. The NVFC is committed to ensuring that volunteer firefighters have an appropriate level of training to safely and effectively carry out the functions of the department(s) that they belong to. 30

“The roles and responsibilities of the fire service have evolved over the years. As the breadth and scope of what it means to be a firefighter has expanded, to varying degrees depending on the jurisdiction, the necessity for training within the fire service has grown. Unfortunately, a large number of volunteer fire departments are still operating with personnel who are not trained to a level consistent with national consensus standards for basic firefighter preparedness. This can lead to ineffective and unsafe responses that put lives and property at risk.” 30 This issue actually encompasses the entire fire service and not just the volunteer ranks.

“As the need for proper training has become more urgent, many volunteer fire departments are finding it increasingly difficult to attract new members. The average age of volunteer firefighters has risen steadily over the past two decades, as many young people move out of rural areas and the ones who stay find themselves with less free time to devote to training.” 30

Standard setting organizations, states and authorities having jurisdiction should move to develop national standards so that fire fighters across the United States are trained to the same minimum levels. The Illinois Fire Service Institute (IFSI) coordinates a statewide training program for individuals interested in becoming a fire fighter. This program offers a 24-hour Basic Fire Fighter course as well as Fire Fighter II and Fire Fighter III certification. The IFSI Fire Fighter II certification is roughly equivalent to the National Fire Protection Association (NFPA) Fire Fighter I and IFSI Fire Fighter III is roughly equivalent to NFPA Fire Fighter II as specified in NFPA 1001 Standard for Fire Fighter Professional Qualifications.1 NFPA FF I reflects minimum training standards for a fire fighter who is always working under supervision. NFPA FF II addresses the assumption of command and transfer of command but does not contain specific job performance requirements (JPRs) to illustrate the required skills. The IFSI 24-hour Basic Fire Fighter course may not properly prepare new fire fighters for the hazards associated with structural fire fighting. Many fire fighters, especially in the volunteer ranks, may be called upon to fill company officer and incident commander roles when they may not have received adequate training to prepare them for the additional responsibilities that are required of fireground officers. At a minimum, fire fighters who serve as company officers and who may be expected to serve as the initial incident commander should receive training equivalent to NFPA Fire Fighter II, as defined by NFPA 1001.

Fire department members that are assigned to or assume supervisory positions at an incident scene must have an additional level of competencies that are necessary to ensure for the safety of themselves and the members they supervise while mitigating the hazard encountered. A company officer must have the correct combination of practical experience, training and skill sets that correspond with their job requirements and expected functions in order to execute the expected duties in a safe, effective, efficient and competent manner. The company officer fulfills a mission critical role within the fire service that directly affects department personnel, public safety and community accord. The title carries with it the opportunity to ride the “front seat” and be in charge of directing a company to address incident operations and demands dictated by the company’s function, responsibility, and task assignment. NFPA 1021, Standard on Fire Officer Professional Qualifications provides clear and concise job performance requirements (JPR) that can be used to determine if an individual, when measured to the standard, possess the skills and knowledge to perform as a fire officer.31 Fire departments should ensure that all fire fighters who are expected to perform the duties of a company officer or greater responsibility have the necessary knowledge, experience and receive adequate training equivalent to NFPA Fire Fighter II, as defined by NFPA 1001 and Fire Officer as defined by NFPA 1021.

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

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

Contributing Factors

 

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

Key Recommendations

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

NIOSH Recommendations

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

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

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

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

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

Hackensack (NJ) Ford Fire July 1, 1988

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

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

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

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

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

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

Street Smarts for Safety and Survival…………Stay safe.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Gloucester City (NJ) Collapse 2002

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

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

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

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

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

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

Philadelphia Inquirer Posting, HERE

Everyone Goes Home Newsletter Article by Chris Collier, HERE

New Jersey Division of Fire Safety LODD Report, HERE

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

UK Firefighter Narrowly Escapes Wall Collapse
Collapse captured on dash cam shows Greater Manchester (UK) Fire and Rescue Service close call

This was recently posted on Firefighternation.com and depicts a a video clip that captures a dramatic near miss of a colleague who could have been killed when a house collapsed today released footage of the incident. Greater Manchester Fire and Rescue Service said the incident in Littleborough, Rochdale, in September 2010 was being released as part of health and safety training for its staff and other fire and rescue services in the UK.

The dramatic footage, caught by a CCTV camera on a fire engine attending the scene, shows a fire fighter narrowly escaping death or serious injury as the front of a derelict terrace house collapsed, almost on top of him. The firefighter seems hardly fazed by the close call.

County Fire Officer and Chief Executive Steve McGuirk said the footage provided terrifying viewing for the service, who would use it as a training example to ensure crew were more aware of the dangers.

He added: “The footage is unbelievable. Our crew and the police are diligently attending this incident, where a derelict property is on fire. But who could have predicted the front of the house would collapse in this way. It is frighteningly close and this fire fighter could so easily have been killed. It’s a powerful example of how our fire fighters put themselves at risk each and every day to keep people across Greater Manchester safe.”

The footage will now form part of the service’s operational assurance processes and used to make fire fighters aware of the potential risks of similar incidents.

Greater Manchester Fire and Rescue Service has 41 stations across the 10 boroughs of the county and attended approximately 50,000 incidents involving fire and collisions on roads and motorways, and other emergencies, last year.

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

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

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

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

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

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

Previous Incident coverage HERE, HERE, HERE and HERE. 

Operations in the Charlie Side Alleyway

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

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

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

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

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

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

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

 

2 Chicago Firefighters Killed: City Had Sued Owners of Building Over Roof Violations: MyFoxCHICAGO.com 

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

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

Anatomy of the Building and Collapse 

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

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

Built-up Bowstring Timber Truss Component

Bearing End of a built-up Bowstring Chord Truss

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

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

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

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

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

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

Collapse Rescue Void Search Operations

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

Typical Pilaster Support

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

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

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

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

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

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

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

The following video clips provide good examples of the extent, physical force and collective momentum of mass that a collapsing section of brick wall can inflict as it fails. These video clips represent multi-floor collapse and variabley larger collapse zones on grade and within the immediate operating areas.

Other Insights and Considerations 

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

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