Bridging The Gap: Fire Safety and Green Buildings Guide

A Fire and Safety Building Guide to Green Construction

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

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

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

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

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

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

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

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

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

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

Construction Site Operational Considerations (not inclusive)

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

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

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

Contributing Factors

 

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

Key Recommendations

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

NIOSH Recommendations

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

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

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

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

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

Hackensack (NJ) Ford Fire July 1, 1988

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Some Open Questions;

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

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

Gloucester City (NJ) Collapse 2002

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

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

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

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

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

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

Philadelphia Inquirer Posting, HERE

Everyone Goes Home Newsletter Article by Chris Collier, HERE

New Jersey Division of Fire Safety LODD Report, HERE

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Roof Collapse Chesapeake VA 1996 Double LODD

OVERVIEW

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

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

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

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

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

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

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

Aerial View 2010 Shopping Center Layout

 

SUMMARY OF KEY ISSUES 

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

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

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

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

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

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

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

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

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

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

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

BUILDING DESCRIPTION - Construction and History 

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

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

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

THE FIRE 

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

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

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

Initial Actions Prior to Calling 911 

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

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

Emergency Response 

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

 

Initial Size-Up and Company Actions 

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

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

 Engine 3 Reports They Are Trapped, Roof Collapses 

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

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

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

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

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

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

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

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

Extinguishment and Body Recovery 

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

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

ANALYSIS 

Fire Cause and Flame Spread 

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

Roof Collapse 

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

  

  

Fire Operations 

  

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

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

  

 

LESSONS LEARNED AND REINFORCED  

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

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

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

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

3. TACTICAL RADIO CHANNELS are essential for firefighter safety. 

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

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

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

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

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

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

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

Charleston Sofa Super Store Fire; Final NIST Report Issued

1 comment

  

The National Institute of Standards and Technology (NIST) has released its final report on its study of the June 18, 2007, fire at the Sofa Super Store in Charleston, S.C., that trapped and killed nine firefighters, the highest number of firefighter deaths in a single event since 9/11. The final report was strengthened by clarifications and supplemental text based on comments provided by organizations and individuals in response to the draft report of the study, released for public comment on Oct. 28, 2010. (HERE) 

The revisions did not alter the study team’s main finding: the major factors contributing to the rapid spread of the fire at the Sofa Super Store were large open spaces with furniture providing high-fuel loads, the inward rush of air following the breaking of windows, and a lack of sprinklers. 

Based on its findings, the study team made 11 recommendations for enhancing building, occupant and firefighter safety nationwide. In particular, the team urged state and local communities to adopt and strictly adhere to current national model building and fire safety codes. These codes are used as models for building and fire regulations promulgated and enforced by U.S. state and local jurisdictions. Those jurisdictions have the option of incorporating some or all of the code’s provisions but often adopt most provisions. 

If today’s model codes had been in place and rigorously followed in Charleston in 2007, the study authors said, the conditions that led to the rapid fire spread in the Sofa Super Store probably would have been prevented. 

  • Specifically, the NIST report calls for national model building and fire codes to require sprinklers for all new commercial retail furniture stores regardless of size, and for existing retail furniture stores with any single display area of greater than 190 square meters (2,000 square feet).
  • Other recommendations include adopting model codes that cover high fuel load situations (such as a furniture store), ensuring proper fire inspections and building plan examinations, and encouraging research for a better understanding of fire situations such as venting of smoke from burning buildings and the spread of fire on furniture.
  • Two of the recommendations in the draft report were slightly modified to increase their effectiveness.
  • The recommendation “that all state and local jurisdictions ensure that fire inspectors and building plan examiners are professionally qualified to a national standard” was improved by listing three nationally accepted certification examinations as examples of “how professional qualification may be demonstrated.”
  • Another recommendation has been enhanced by urging state and local jurisdictions to “provide education to firefighters on the science of fire behavior in vented and non-vented structures and how the addition of air can impact the burning characteristics of the fuel.”

Based on their model and the data collected, the NIST researchers determined the following sequence of events on June 18, 2007, at the Sofa Super Store:

  • The fire began in trash outside the loading dock and spread into the enclosed loading dock. The fire spread from the exterior to the interior of the loading dock, which was used for staging furniture for delivery and repair. The fire spread quickly within the loading dock and moved into both the retail showroom and warehouse spaces.
  • During the early stages of this fire, the fire was unable to access enough air, a state that slowed its growth. However, the lack of sufficient air for complete combustion did result in large volumes of smoke and combustible gases flowing into the space below the roof and above the drop ceiling of the main retail showroom.
  • The fire spread to the rear of the main showroom through the holding area and ignited additional fuel in the rear of the main showroom, at which time it became more visible to firefighters in the main showroom.
  • The growth of the fire at the back of the main showroom was still slowed by the lack of air. As the fire burned in the rear of the main showroom, the fire pumped more hot unburned fuel into the smoke layer below the drop ceiling. The lack of air prevented the unburned fuel in the smoke layer from igniting.
  • When the front windows were broken (approximately 24 minutes after firefighters arrived at the store), additional air flowed in the front windows, along the floor and to the rear of the showroom, and became available to the fire. The additional air allowed the burning rate of the fire to increase rapidly and ignite the layer of unburned fuel below the drop ceiling.
  • The fire swept from the rear to the front of the main showroom extremely quickly, then into the west and east showrooms, trapping six firefighters in the main showroom and three firefighters in the west showroom.
  • Furniture and merchandise in the showrooms and warehouse continued to burn for an additional 140 minutes before the fire was extinguished.

NIST is working with various public and private groups toward implementing changes to practices, standards, and building and fire codes based on the findings from this study.

jurisdictions have the option of incorporating some or all of the code’s provisions but generally adopt most provisions. 


Recommendations from the NIST Study of the Charleston Sofa Super Store Fire

1. High Fuel-Load Mercantile Occupancies: NIST recommends that, at a minimum, all state and local jurisdictions adopt a building and fire code based upon one of the model codes, covering new and existing high fuel-load mercantile occupancies, and update local codes as the model codes are revised. 

2.   Model Code Adoption and Enforcement: NIST recommends that all state and local jurisdictions implement aggressive and effective fire inspection and enforcement programs that address: 

a) all aspects of the building and fire codes;
b) adequate documentation of building permits and alterations;
c) the means of inspecting fire protection systems and detailing record keeping;
d) the frequency and rigor of fire inspections, including follow-up and auditing procedures; and
e) guidelines for remedial requirements when inspections identify deviations from code provisions. 

3.  Qualified Fire Inspectors and Building Plan Examiners: NIST recommends that all state and local jurisdictions ensure that fire inspectors and building plan examiners are professionally qualified to a national standard such as National Fire Protection Association (NFPA) 1031. 

4.  Sprinklers: NIST recommends that model codes require sprinkler systems and that state and local authorities adopt and aggressively enforce this provision: 

a) for all new commercial retail furniture stores regardless of size; and
b) for existing retail furniture stores with any single display area of greater than 190 square meters (2,000 square feet). 

5.  Comprehensive Risk Management Plans:  NIST recommends that state and local jurisdictions use comprehensive risk management plans to: 

a) identify low, medium, and high hazard occupancies;
b) allocate resources according to risk identified; and
c) develop operating procedures that respond to specific risks. 

6.  Ventilation of Burning Structures: NIST recommends that state and local authorities:  

a) develop guidelines as to how and when ventilation should be implemented during a fire; and
b) provide training to fire fighters on different types of ventilation—vertical, horizontal and positive-pressure—and integrate into daily operations on the fire ground. 

7.  Research on Upholstered Furniture Flame Spread: NIST recommends that research be conducted to better understand ignition and fire spread on upholstered furniture in order to provide the tools needed by design professionals to improve the fire performance of furniture. The specific areas requiring research are: 

a) prediction of ignition of natural and synthetic coverings for current furniture, wall, ceiling and floor lining materials, and room furnishings;
b) prediction of fire spread over actual furniture with and without fire barriers, fire retardants and fire resistive materials; and
c) quantification of smoke and toxic gas production in realistic room fires. 

8.  Research on Improving Fire Barriers: NIST recommends that research be conducted to provide the tools needed by design professionals to improve the performance of compartmentalization. The specific areas requiring research are: 

a) prediction of fire spread through walls constructed of wood, metal and gypsum wallboard;
b) prediction of fire spread through doors constructed of glass, wood, and metal;
c) prediction of fire spread through penetrations; and
d) prediction of performance of roll-up fire doors in actual fires and after extended service.  

9.  Research on Decision Aids for Allocation of Resources: NIST recommends that research be conducted to: 

a) refine computer-aided decision tools for determining the costs and benefits of alternative code changes and fire safety technologies; and
b) develop computer models to assist communities in allocating resources (money and staff) to ensure that their response to an emergency with a large number of potential casualties is effective. 

10.  Research on Ventilation of Burning Structures: NIST recommends that additional research be conducted to: 

a) improve characterization of how ventilation affects the growth and spread of fire within structures; and
b) provide the fire service with guidance on when and how to use ventilation to improve the fire environment during fire service operations. 

11.  Research on Performance Metrics for Fire Protection: NIST recommends that research be conducted to: 

a) develop performance and effectiveness metrics for community fire protection;
b) survey effectiveness of existing fire services; and
c) use metrics to optimize development of new technologies. 


 

 

 

 

 

 

Attic Fires in Residential Buildings Report

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

According to the report:   

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

Attic Fires in Residential Buildings is part of the USFA’s Topical Fire Report Series. Topical reports explore facets of the U.S. fire problem that USFA shares with fire departments and first responders around the country to help them keep their communities safe. Each report briefly addresses the nature of the specific fire or fire-related topic, highlights important findings from the data, and may suggest other resources to consider for further information. Also included are recent examples of fire incidents that demonstrate some of the issues addressed in the report or that put the report topic in context.   

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

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

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

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

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

In order to provide support for continuing training and insight opportunities, I’ve developed a PDF download of the Chicago: Anatomy of a Building and its Collapse article in its entirety.
A power point program will be forthcoming to accompany both media items.

Remember: Building Knowledge = Firefighter Safety

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

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

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

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

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

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

Previous Incident coverage HERE, HERE, HERE and HERE. 

Operations in the Charlie Side Alleyway

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

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

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

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

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

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

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

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

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

Anatomy of the Building and Collapse 

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

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

Built-up Bowstring Timber Truss Component

Bearing End of a built-up Bowstring Chord Truss

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

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

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

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

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

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

Collapse Rescue Void Search Operations

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

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. 

Typical Truss End w Bottom Chord, Steel End Shoe and Load Bearing Plate on a Pilaster

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.

Bowstring Truss Profile

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

Other Insights and Considerations 

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

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

Collapse of Bowstring Truss Roof Seriously Injures Fire Fighter

5 comments

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

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

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

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

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

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

Key contributing factors identified in this investigation include:  

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

STRUCTURE

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

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

Aerial view of Building

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

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

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

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

Similar Interior Construction Features

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

TRAINING and EXPERIENCE

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

INVESTIGATION INSIGHTS

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

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

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

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

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

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

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

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

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

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

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

Collapse into the street on Alpha Side

 

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

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

NIOSH RECOMMENDATIONS  

  • Recommendation #1: Fire departments should ensure that they have consistent policies and training on an incident management system.
  • Recommendation #2: Fire departments should develop, implement and enforce written standard operating procedures (SOPs) that identify incident management training standards and requirements for members expected to serve in command roles
  • Recommendation #3: Fire departments should ensure that the incident commander conducts an initial size-up and risk assessment of the incident scene before beginning fire fighting operations
  • Recommendati on #4: Fire departments should ensure that the first due company officer establishes a stationary command post, maintains the role of director of fireground operations, and does not become involved in firefighting efforts.
  • Recommendation #5: Fire departments should develop, implement and enforce written standard operating procedures that define defensive fire fighting operations.
  • Recommendation #6: Fire departments should ensure that policies are followed to establish and monitor a collapse zone when conditions indicate the potential for structural collapse.
  • Recommendation #7: Fire departments should train all fire fighting personnel in building construction and in the risks and hazards related to structural collapse.
  • Recommendation #8: Fire departments should conduct pre-incident planning inspections of buildings within their jurisdictions to facilitate development of safe fireground strategies and tactics.
  • Discussion: NFPA 1620 Standard for Pre-Incident Planning, states “The purpose of this document shall be to develop pre-incident plans to assist responding personnel in effectively managing emergencies for the protection of occupants, responding personnel, property, and the environment.” A pre-incident plan identifies deviations from normal operations and can be complex and formal, or simply a notation about a particular problem such as the presence of flammable liquids, explosive hazards, modifications to structural building components, or structural damage from a previous fire.
  • Building characteristics including type (or more importantly risk) of construction, materials used, occupancy, fuel load, roof and floor design, and unusual or distinguishing characteristics should be recorded, shared with other departments who provide mutual aid, and if possible, entered into the dispatcher’s computer so that the information is readily available if an incident is reported at the noted address.
  • Since many fire departments have tens and hundreds of thousands of structures within their jurisdiction, it is a challenge to establish an effective preplanning system. Priority should be given to those having elevated or unusual fire hazards and life safety considerations.
  • One tool for fire departments to use in assessing their risks for structures within their jurisdictions is the mnemonic, BECOME SAFE: (HERE) 
    • Building
    • Evaluation
    • Construction/occupancy
    • Operational hazards
    • Manage time and elements
    • Engagement
    • Situational awareness
    • Assessment and risk analysis
    • Fire behavior and effects
    • Evaluate and execute  
 
 

BECOME SAFE by CJ Naum

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

The construction features of occupancy (bowstring truss), possible commercial fuel loads and access restrictions suggested large volumes of water would be necessary to fight a major fire at the site. A more complete pre-planning process, involving individual fire companies within their response territory could have noted this information which may have aided the IC in developing a safer and more effective offensive or defensive strategy. In order to facilitate open communication, fire department personnel and building code officials should be cross-trained on each-others’ duties and responsibilities.  

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

Fire Service Features of Buildings and Fire Protection Systems

Fire Service Features of Buildings and Fire Protection Systems

Fire Service Features of Buildings and Fire Protection Systems is a very useful manual that was developed and published by the Occupational Safety and Health Administration, U.S. Department of Labor for the purpose to increase the safety of building occupants and emergency responders by streamlining fire service interaction with building features and fire protection systems.

The information in this manual will assist designers of buildings and fire protection systems to better understand the needs of the fire service when they are called upon to operate in or near the built environment and provide fire service personnel with a greater degree of understanding  and be able to interface with governmental and design professionals for improved fire protection features and arrangements.

To put this another way, architects and engineers create workplaces for firefighters. Designs can be tailored to better meet operational needs, thereby reducing the time it takes to mitigate an incident. The guidance in this manual is expected to decrease the injuries to responding and operating fire service personnel. When an incident can be mitigated faster, there is less time for the hazardous situation to grow in proportion. With less potential exposure, employees occupying buildings will be afforded greater protection from fire incidents.

Employee occupants as well as fire service employees will realize the benefits of this manual in terms of safe working conditions as intended by the Occupational Safety and Health Act of 1970. The codes and standards governing buildings and fire protection systems are well understood by designers. However, many portions of these codes and standards allow design variations or contain only general performance language. The resulting flexibility permits the selection of different design options. Some of these options may facilitate fire service operations better than others.

The particular needs and requirements of the fire service are typically not known thoroughly by persons not associated with these operations. This manual discusses how the fire service interacts with different building features and it suggests methods for streamlining such interaction. To provide the most effective protection, fire service personnel should be considered as users of building features and fire protection systems. While far less frequent than mechanical events or other failures, fire can cause greater destruction in terms of property loss, disruption of operations, injury, and death.

Designers routinely consider the needs and comfort of building occupants when arranging a building’s layout and systems. Within the framework of codes and standards, design options may be exercised to benefit a particular owner, tenant, or user. For example, a building code would typically dictate the minimum number of lavatories and water fountains. However, the location, distribution, and types of such facilities are left to the designer in consultation with the client.

The application of fire protection features in buildings is similar. For instance, a fire code may require the installation of a fire department connection for a sprinkler system or an annunciator for a fire alarm system. However, there may be little or no guidance as to the location, position, features, or marking of such devices. This manual provides this type of guidance to designers. However, specific local requirements or preferences may differ. Input should always be obtained from local code officials and the fire service organization, the “client” in this case.

This manual is to be used voluntarily, as a companion to mandatory and advisory provisions in building codes, life safety codes, fire codes, safety regulations, and installation standards for fire protection systems. The material contained in this document focuses on ways that safety of building occupantsdesigners can contribute to the efficiency of fire suppression operations. This material is applicable to all fire service organizations, including fire brigades and fire departments.

Taking it to the Streets with Christopher Naum

Wednesday Night’s Program has been postponed due to Emergent Server issues at BlogTalkRadio.

The Program has been rescheduled for Thursday November 4th at 9:00pm EDT

Turn Out to FireFighter NetCast.com and Taking it to the Streets for; “Redefining the Fire Ground”

If you missed last month’s program on the Tactical Renaissance of Combat Fire Suppression Operations and the new Rules of Engagement, with Chief Gary Morris (ret) Phoenix (AZ) Fire Department and Dr. Burt Clark from the NFA, then you missed out a some great insights and discussion. This month Taking it to the Streets is looking to further the dialog and look at “Redefining the Fire Ground”. Many would argue that the fire ground doesn’t need to be “redefined”; that the way we do business in the Streets is just fine and that the American Fire Service knows how to get the job done, at any cost.

The recent release of the NIST Technical Study of the Sofa Super Store Fire – South Carolina, June 18, 2007 has presented compelling data and information that provides further discernments of how our buildings react under fire conditions and how our tactical assumptions and deployments continue to be willfully miscued.  Joining Chris will be Chief Douglas Cline, from the City of High Point FD, North Carolina, a highly regarded national instructor, author, advocate, tactician and incident command.

Don’t miss out on debating and dialoging the transitional fire ground. It is here and it’s here to stay; you just didn’t know that it was changing. But then again, was anyone paying attention?  Join the live broadcast on Thursday night November 4th at 9:00pm ET, or download the post production podcast from Firefighter NetCast.com.

NIST Study on Charleston Furniture Store Fire Calls for National Safety Improvements

1 comment

Major factors contributing to a rapid spread of fire at the Sofa Super Store in Charleston, S.C., on June 18, 2007, included large open spaces with furniture providing high fuel loads, the inward rush of air following the breaking of windows and a lack of sprinklers, according to a draft report released for public comment today by the U.S. Commerce Department’s National Institute of Standards and Technology (NIST). The fire trapped and killed nine firefighters, the highest number of firefighter fatalities in a single event since 9/11.

Based on its findings, the NIST technical study team made 11 recommendations for enhancing building, occupant and firefighter safety nationwide. In particular, the team urged state and local communities to adopt and strictly adhere to current national model building and fire safety codes.1 If today’s model codes had been in place and rigorously followed in Charleston in 2007, the study authors said, the conditions that led to the rapid fire spread in the Sofa Super Store probably would have been prevented.

“Furniture stores typically have large amounts of combustible material and represent a significant fire hazard,” said NIST study leader Nelson Bryner. “Model building codes should require both new and existing furniture stores to have automatic sprinklers, especially if those stores include large, open display areas.”

Specifically, the NIST report calls for national model building and fire codes to require sprinklers for all new commercial retail furniture stores regardless of size, and for existing retail furniture stores with any single display area of greater than 190 square meters (2,000 square feet). Other recommendations include adopting model codes that cover high fuel load situations (such as a furniture store), ensuring proper fire inspections and building plan examinations, and encouraging research for a better understanding of fire situations such as venting of smoke from burning buildings and the spread of fire on furniture.

Using a state-of-the-art computer model to simulate the fire, the study team found that the addition of automatic sprinklers inside the loading dock could have significantly slowed the fire (which began just outside the dock area), prevented it from spreading beyond the dock, and eventually, extinguished it completely. The model also showed that sprinklers on the loading dock likely would have maintained what firefighters call tenability conditions, the ability for individuals in a fire event to escape unassisted.

Factors identified as contributing to the fire’s progress include: (1) the high fuel loads—especially furniture—present throughout the building; (2) the lack of sprinklers throughout the Sofa Super Store; (3) the open floor plan of the facility; (4) the hidden build-up of combustible smoke and gases in the area between the drop ceiling and the roof of the main showroom; (5) the non-fire-activated roll-up door that was open between the loading dock and the holding area; (6) the four fire-activated roll-up doors (out of seven) that activated but did not close during the fire; (7) the metal walls in the warehouse and west showroom that allowed heat from the fire to ignite items next to the walls; and (8) the breaking of windows at the front of the store that supplied air to the fire.

NIST’s team of experts traveled to Charleston to gather data within 36 hours of the Sofa Super Store fire. Using these data and other information collected in the following months (such as building design documents, records, plans, video and photographic data, radio transmissions, interviews with emergency responders, and informal discussions with store employees), the NIST study team developed its computer model to simulate and analyze the characteristics of the fire, including fire spread, smoke movement, tenability, and the operation of active and passive fire protection systems.

Based on their model and the data collected, the NIST researchers determined the following sequence of events on June 18, 2007, at the Sofa Super Store:

  • The fire began in trash outside the loading dock and spread into the enclosed loading dock. The fire spread from the exterior to the interior of the loading dock, which was used for staging furniture for delivery and repair. The fire spread quickly within the loading dock and moved into both the retail showroom and warehouse spaces.
  • During the early stages of this fire, the fire was unable to access enough air, a state that slowed its growth. However, the lack of sufficient air for complete combustion did result in large volumes of smoke and combustible gases flowing into the space below the roof and above the drop ceiling of the main retail showroom.
  • The fire spread to the rear of the main showroom through the holding area and ignited additional fuel in the rear of the main showroom, at which time it became more visible to firefighters in the main showroom.
  • The growth of the fire at the back of the main showroom was still slowed by the lack of air. As the fire burned in the rear of the main showroom, the fire pumped more hot unburned fuel into the smoke layer below the drop ceiling. The lack of air prevented the unburned fuel in the smoke layer from igniting.
  • When the front windows were broken (approximately 24 minutes after firefighters arrived at the store), additional air flowed in the front windows, along the floor and to the rear of the showroom, and became available to the fire. The additional air allowed the burning rate of the fire to increase rapidly and ignite the layer of unburned fuel below the drop ceiling.
  • The fire swept from the rear to the front of the main showroom extremely quickly, then into the west and east showrooms, trapping six firefighters in the main showroom and three firefighters in the west showroom.
  • Furniture and merchandise in the showrooms and warehouse continued to burn for an additional 140 minutes before the fire was extinguished.

The complete draft report is available online at http://www.nist/gov/el

NIST welcomes comments on the draft report and its recommendations. To be considered for the final report, comments must be received by noon EST on Dec. 2, 2010. Comments may be submitted via e-mail to firesafety@nist.gov; fax to (301) 975-4052; or mail to the attention of NIST Technical Study: Sofa Super Store, NIST, 100 Bureau Dr., Stop 8660, Gaithersburg, MD 20899-8660.

Once the final report is published, NIST will work with the appropriate committees of the International Code Council (ICC) on using the study’s recommendations to improve provisions in model building and fire codes. NIST also will work with the major organizations representing state and local governments—including building and fire officials—and firefighters to encourage them to seriously consider its recommendations.

Recommendations from the NIST Study of the Charleston Sofa Super Store Fire

1. High Fuel-Load Mercantile Occupancies: NIST recommends that, at a minimum, all state and local jurisdictions adopt a building and fire code based upon one of the model codes, covering new and existing high fuel-load mercantile occupancies, and update local codes as the model codes are revised.

2.   Model Code Adoption and Enforcement: NIST recommends that all state and local jurisdictions implement aggressive and effective fire inspection and enforcement programs that address:

a) all aspects of the building and fire codes;
b) adequate documentation of building permits and alterations;
c) the means of inspecting fire protection systems and detailing record keeping;
d) the frequency and rigor of fire inspections, including follow-up and auditing procedures; and
e) guidelines for remedial requirements when inspections identify deviations from code provisions.

3.  Qualified Fire Inspectors and Building Plan Examiners: NIST recommends that all state and local jurisdictions ensure that fire inspectors and building plan examiners are professionally qualified to a national standard such as National Fire Protection Association (NFPA) 1031.

4.  Sprinklers: NIST recommends that model codes require sprinkler systems and that state and local authorities adopt and aggressively enforce this provision:

a) for all new commercial retail furniture stores regardless of size; and
b) for existing retail furniture stores with any single display area of greater than 190 square meters (2,000 square feet).

5.  Comprehensive Risk Management Plans:  NIST recommends that state and local jurisdictions use comprehensive risk management plans to:

a) identify low, medium, and high hazard occupancies;
b) allocate resources according to risk identified; and
c) develop operating procedures that respond to specific risks.

6.  Ventilation of Burning Structures: NIST recommends that state and local authorities: 

a) develop guidelines as to how and when ventilation should be implemented during a fire; and
b) provide training to fire fighters on different types of ventilation—vertical, horizontal and positive-pressure—and integrate into daily operations on the fire ground.

7.  Research on Upholstered Furniture Flame Spread: NIST recommends that research be conducted to better understand ignition and fire spread on upholstered furniture in order to provide the tools needed by design professionals to improve the fire performance of furniture. The specific areas requiring research are:

a) prediction of ignition of natural and synthetic coverings for current furniture, wall, ceiling and floor lining materials, and room furnishings;
b) prediction of fire spread over actual furniture with and without fire barriers, fire retardants and fire resistive materials; and
c) quantification of smoke and toxic gas production in realistic room fires.

8.  Research on Improving Fire Barriers: NIST recommends that research be conducted to provide the tools needed by design professionals to improve the performance of compartmentalization. The specific areas requiring research are:

a) prediction of fire spread through walls constructed of wood, metal and gypsum wallboard;
b) prediction of fire spread through doors constructed of glass, wood, and metal;
c) prediction of fire spread through penetrations; and
d) prediction of performance of roll-up fire doors in actual fires and after extended service. 

9.  Research on Decision Aids for Allocation of Resources: NIST recommends that research be conducted to:

a) refine computer-aided decision tools for determining the costs and benefits of alternative code changes and fire safety technologies; and
b) develop computer models to assist communities in allocating resources (money and staff) to ensure that their response to an emergency with a large number of potential casualties is effective.

10.  Research on Ventilation of Burning Structures: NIST recommends that additional research be conducted to:

a) improve characterization of how ventilation affects the growth and spread of fire within structures; and
b) provide the fire service with guidance on when and how to use ventilation to improve the fire environment during fire service operations.

11.  Research on Performance Metrics for Fire Protection: NIST recommends that research be conducted to:

a) develop performance and effectiveness metrics for community fire protection;
b) survey effectiveness of existing fire services; and
c) use metrics to optimize development of new technologies.

NIST has more than 40 years of experience conducting building and fire safety studies and researching the aftermath of disasters and failures. By understanding the technical causes for such incidents and making the information available to the public, NIST scientists and engineers strive to improve the safety of buildings, their occupants and emergency responders.

    The NIOSH Fire Fighter Fatality Investigation and Prevention Program has released the investigation report of the line of duty deaths of two career FDNY  firefighters during a 2007 seven-alarm high-rise fire in the former Deutsche Bank building undergoing deconstruction and asbestos abatement.

    On August 18, 2007,  two FDNY firefighters; Fr. Joseph Graffagnino and Fr. Robert Beddia both assigned to Engine 24 and Ladder 5 in SoHo lost thier lives while operating at this incident. The seven alarm fire was being worked with a contingent of over 275 firefighters when the pair became trapped on the 14th floor of the building after being overcome by blinding concentrations of dense smoke after their air supply was depleted during the course of combat fire suppression operations. FDNY Fr. Robert Beddia a twenty-three year veteran and FDNY Fr. Joseph Graffagnino,  became trapped in the maze-like conditions of a high-rise building undergoing deconstruction. The building’s standpipe system had been disconnected during the deconstruction and the partitions constructed for asbestos abatement prohibited fire fighters from getting water to the seat of the fire. An hour into the incident, the fire department was able to supply water by running an external hoseline up the side of the structure. Soon after the victims began to operate their hoseline, they ran out of air. The victims suffered severe smoke inhalation and were transported to a metropolitan hospital in cardiac arrest where they succumbed to their injuries.

    By the time the fire was extinguished, 115 fire fighters had suffered a variety of injuries.Key contributing factors to this incident include: delayed notification of the fire by building construction personnel, inoperable standpipe and sprinkler system, delay in establishing water supply, inaccurate information about standpipe, unique building conditions with both asbestos abatement and deconstruction occurring simultaneously, extreme fire behavior, uncontrolled fire rapidly progressing and extending below the fire floor, blocked stairwells preventing fire fighter access and egress, maze-like interior conditions from partitions and construction debris, heavy smoke conditions causing numerous fire fighters to become lost or disoriented, failure of fire fighters to always don SCBAs inside structure and to replenish air cylinders, communications overwhelmed with numerous Mayday and urgent radio transmissions, and lack of crew integrity.

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

    • review and follow existing standard operating procedures on high-rise fire fighting to ensure that fire fighters are not operating in hazardous areas without the protection of a charged hoseline.
    • be prepared to use alternative water supplies when a building’s standpipe system is compromised or inoperable.
    • develop and enforce risk management plans, policies, and standard operating guidelines for risk management during complex high-rise operations.
    • ensure that crew integrity is maintained during high-rise fire suppression operations.
    • train fire fighters on actions to take if they become trapped or disoriented inside a burning high-rise structure.
    • ensure that fire fighters diligently wear their self-contained breathing apparatus (SCBA) when working in environments that are immediately dangerous to life and health (IDLH).
    • train fire fighters in air management techniques to ensure they receive the maximum benefit from their self-contained breathing apparatus (SCBA).
    • use exit locators (both visual and audible) or safety ropes to guide lost or disoriented fire fighters to the exit.
    • conduct pre-incident planning inspections of buildings within their jurisdictions to facilitate development of safe fireground strategies and tactics.
    • encourage building owners and occupants to report emergency situations as soon as possible and provide accurate information to the fire department.
    • consider additional fire fighter training using a high-rise fire simulator.

    Manufacturers, equipment designers, and researchers should:

    • conduct research into refining existing and developing new technology to track the movement of fire fighters in high-rise structures.
    • continue to develop and refine durable, easy-to-use radio systems to enhance verbal and radio communications in conjunction with properly worn self-contained breathing apparatus (SCBA).
    Municipalities should:

    • ensure that construction and/or demolition is done in accordance with NFPA 241: Standard for Safeguarding Construction, Alteration, and Demolition Operations.
    • develop a reporting system to inform the fire department of any ongoing, unique building construction activities (such as deconstruction or asbestos abatement) that would adversely affect a fire response.
    • establish a system for property owners to notify the fire department when fire protection/suppression systems are taken out of service.

    Operational Safety at Buildings Under Renovation

    No comments

    httpv://www.youtube.com/watch?v=8F_rSeUQQYM

    A multiple alarm fire consumed the county courthouse in downtown Pittsboro, North Carolina yesterday. The building was undergoing renovations at the time of the fire and was occupied and operational. The fire started in the clock tower of the 130-yr.-old building and is believed to have been caused by welders.  The entire building was undergoing renovation with the outside enclosed with scaffolding. 

    The clock tower had a protective tarp wrapped around it that preventing outside hose streams from reaching the seat of the fire. The fire broke out at 4:45 p.m., according to county and court officials, shortly after court sessions had ended. All who worked in the building were evacuated safely, according to county officials, and no injuries had been reported late Thursday. According to published reports, the courthouse, the centerpiece of the Pittsboro downtown, was built in stages. It was initially constructed in 1881 at a cost of $10,666, according to Paul Shield Crane’s first edition of “North Carolina Taproots: Courthouses of North Carolina.” In 1930, another story was added to the brick building and, in 1959, there was an extensive renovation that cost $130,000.

    Bottom line, buildings undergoing construction, alterations, deconstruction, demolition and renovations can pose significant risk to suppression operations and lead to firefighter injuries and fatalities. This can not be stressed enough.

    The unique and dangerous elements confronting incident commanders, company officers and operating forces demands a clear understanding that fire suppression operations in buildings during construction, alterations, deconstruction, demolition and renovations present significant risks and consequences, requires a methodical and conservative approach towards incident stabilization and mitigation. You cannot implement conventional tactical operations in these structures. Doing so jeopardizes all operating personnel and creates unbalanced risk management profiles that are typically not favorable to the safety and wellbeing of firefighters.

       14

     

    The following are assessment considerations that may provide insights in the assessment, risk profile and development of pre-fire plans, operational procedures and field directives to prevent history repeating events (HRE) with similar conditions and attributes;

     Construction Type

    • What is the construction type or mixed application? How does this affect suppression, rescue, special operations and typical daily operations?
    • Stage and/or Phase of construction, alterations, deconstruction, demolition and renovations
    • The Stage and/or phase of construction, alterations, deconstruction, demolition and renovation has, SIGNIFICANT impact on firefighter safety and operational integrity.
    • Understanding these stages and phases can provide mission critical decision-making considerations to incident management teams and company officers.

     Site conditions and accessibility

    • Considerations for both horizontal, vertical and grade conditions.
    • Considerations during changes in stages and phases. Expect changes
    • Conduct periodic command and company level inspections and walk-through’s

     Exposures

    • These will be specific to the commonality or uniqueness of the structure and occupancy.

     Resources

    • Do you have enough of what’s going to be needed? Plan for it now, before you’re in the street needing it “yesterday”.
    • Think BIG, as the adage goes, you can always send the companies back. Don’t under estimate the types and kind of resources needs, based upon the structure profile and the potential of undetermined conditions. (reinforces need for pre-planning)
    • Share the Knowledge, Situational Awareness and Pre-planning inf
      ormation with other agencies (resources) you may call upon to support escalating or multiple alarm events.

     Operating procedures
    Again, response and operations at these types of structures demands that pre-fire plan considerations, dialog, discussions, communications and what ever else is appropriate to you organization is identified and disseminated BEFORE an alarm response occurs. Take advantage of pre-gaming and table top a target occupancy, to increase preparedness and reduce risk potential.

    • Conduct periodic command and company level inspections and walk-through’s
    • Update the plans as conditions change
    • Share the information with other agencies (resources) you may call upon to support escalating or multiple alarm events.

     Knowledge and Situational Awareness

    • Understand, explore, research and obtain ALL the necessary information on the structure(s) undergoing construction, alterations, deconstruction, demolition and renovations
    • Conduct periodic command and company level inspections and walk-through’s
    • Communicate the observations, findings, conditions and considerations.

     Communications

    • What ever you identify- COMMUNICATE this throughout the organization.
      Share the information with other agencies (resources) you may call upon to support escalating or multiple alarm events.

     Special and Unique Conditions

    • Identify and plan for the Special and Unique Conditions that may exclusive to you jurisdiction’s structure undergoing construction, alterations, deconstruction, demolition and renovations.

     Contingency Plans

    • Plan of the unexpected and have contingent plans in place.

     The magnitude and complexity of an incident involving a structure undergoing construction, alterations, deconstruction, demolition and renovations will be directly proportional to the size of the building/construction site and corresponding age profile (vintage) of the existing building, if under renovation, and degree of construction. Operational deployment and the Incident Action Plan- IAP must be addressed during strategic and tactical incident management, risk profiling and pre-incident and on-scene intelligence, reconnaissance and planning considerations: More HERE

    august_detailAs we transition into a new year, and as plans begin to take place that frame and outline the year’s activities, foremost in this planning, preparation, scheduling and outlook should be those activities and commitments that training, education and skill development can be implemented and enhanced. Take the initiative to recognize and identify training and operational gaps and distinguish the risk and options available to lessen or eliminate the risk and reduce the gap deficiencies. Take the time to implement effective, accurate and frequent training and skill development drills, training curriculums and programs.

    Don’t sacrifice or forego on this mission critical area when so much is at stake in the domain of combat structural fire suppression. Understand the predictability of performance in the buildings and occupancies not only in your jurisdiction, first or second-due areas, but also in those areas that you may be called upon to respond to for greater alarms or mutual aid. Remember Building Knowledge = Firefighter Safety.

    Keep an eye in the rear view mirror; learning from the wisdom and knowledge from where you’ve been, what you’ve done and all your past experiences and practice; but at the same time focusing on the road before you with keen attentiveness on situational awareness, anticipating error-likely conditions and balanced risk assessment and operational management in both your strategic and tactical deployments.

    Buildings Under Construction

    1 comment

    It’s been a busy week for a couple of departments nationally with major fires at buildings under construction. A multiple alarm fire struck a 5 –story Apartment Complex in Renton, Washington that occupies nearly a full city block on Tuesday June 30th, HERE and HERE for details.

    On Monday June 29th, a spectacular multiple alarm fire destroyed approximately 55 townhouses that were under construction in Mississauga, Ontario Canada. HERE and HERE for details.

    Buildings and construction sites pose unique strategic and tactical operational profiles and are considered high risk incidents to both manage and operate at. What were the operational and safety issues you may have encountered at similar events in your own jurisdiction?

    Check out the Ten Minutes in the Street: Buildings under Construction-Fire Scenario posted at FFN, HERE
    The building environments that form and shape our respective response districts pose unique challenges to the day-to-day responses of fire departments and their subsequent operations at structural alarms. With the variety of occupancies and building characteristics present, there are definable degrees of risk potential with recognizable measures that must be taken.

    Although each occupancy type presents variables that dictate how a particular incident is handled, most company operations evolve from basic strategic and tactical principles rooted in past performance and operations at similar structures. With any structure, regardless of its construction type, materials, occupancy classification, age or size, the majority of incidents requiring actual operation time occur when the structure is in use or vacant.

    But what about the early stages of the life cycle of a building – when a company is called to respond to an incident at a building under construction or at a construction site? Fire department responses and operations at building and construction sites present unique circumstances and considerations that are not part of that day-to-day alarm response procedure.

    During the construction process, building and construction sites represent the highest potential for fire, injuries and large-scale operations than at any other time within the life cycle of a structure. When completed, the building may have state-of-the-art detection and suppression equipment present, it may be compartmentalized and use the best fire resistive materials available. However, during the construction process the building represents a high-risk target hazard with the potential to stretch to the limit the capabilities and resources of any fire service agency.

    Buildings can be classified within five fundamental construction types:

    • Fire-Resistive
    • Non-Combustible
    • Ordinary (exterior protected)
    • Heavy Timber
    • Wood Frame

    These are represented in various forms and sub-classifications within the NFPA 220 Standard on Types of Building Construction, as well as other Model Codes

    Regardless of construction classification, during the construction process each building can be affected adversely by flame and heat impingement due to fires, weather and environmental conditions, improper or inadequate construction techniques and methods as well as substandard or inappropriate construction materials and system assemblies.

    When referring to the broad range of building and construction sites, there are five general classifications for most projects:

    • Renovations
    • Rehabilitations
    • Conversions
    • Expansions
    • New construction

    Although there are some overlaps, each project presents hazards that affect life safety, structural integrity and exposures. Projects within the renovation and rehabilitation areas may include vacant or abandoned structures that are transformed into new occupancy/use buildings, or can include older structures that are brought back to their original state. Current development trends are those in which older structures of brick-and-joist construction typically are renovated into commercial shopping centers, apartments and mixed-use occupancies. In many instances, the building interiors are altered extensively to accommodate the design criteria and, in doing so, may alter the integrity of the structures.

    Conversions usually involve change from one occupancy use to another. For example, a factory used for manufacturing is converted into arts and crafts shops or into a multiple-occupancy facility. Most sought after structures of this kind include the heavy timber building (New England Mill Type) as well as old, reinforced concrete frame or steel-framed factory or manufacturing structures. Expansions, on the other hand, constitute existing buildings that broaden their building layouts and floor areas to accommodate the owners’ needs. Many times the buildings will stay in operation while the expansion construction is undertaken, creating myriad life safety, suppression and control concerns.

    New construction involves site preparation, mobilization of materials and manpower and the evolution of a new structure. Each project category, when coupled with a specific construction type, presents specific hazards and conditions that must be identified, assessed and acted upon correctly. The potential that exists in any construction area during fire department response can include, but not be limited to:

    • Fire
    • Explosions
    • Collapse
    • Excavation & Trench Cave-In
    • Compromised Structural Conditions
    • Hazardous Materials Situations
    • Accidents
    • Failures

    The ability for a fire department to intervene in the progression of an incident will be related directly to the magnitude of the incident, its complexity and its demands on resources, manpower and technical based competencies, familiarity with the site and construction methods used, the stage of construction, as well as the effectiveness of SOP’s/ SOG’s, communications and the incident command management structure of the involved agency.

    The most critical aspect to any operation in a building or on a construction site is the effect the incident will have upon the surrounding area or construction. The hazards present on a building and/or construction site pose threats to workers on the site, firefighters, civilians and exposures. Any one of these categories can strain an operation and response. But add two, three or all four concerns and the situation, however small initially, can escalate into a complex operation involving multiple agencies and resources. All with variable risks for significant challenge to firefighter survivability and injuries.

    Exposure threa
    t to site workers creates life safety concerns that require determination of their work area assignments, numbers present and actual location for accountability. Information detailing the magnitude of the life safety concerns can be derived from on-site field offices and contractors’ trailers. The ability to relocate personnel from areas of immediate danger to an area of safe refuge may prove to be a major strategic undertaking. Limited access points, passenger elevator cranes and hoist ways present life safety concerns. Incident commanders and company officers also must consider firefighter life safety and have the ability to judge operational areas and surrounding construction exposures. Ventures into areas of recent concrete pours (“green” concrete) or suppression operations involving wood shoring, formwork or unprotected steel components could be fatal if decisions are based on faulty operations and decision-making parameters.

    Civilian dangers include situations involving equipment failures, material drops and toxic products of combustion. Recent incidents involving crane collapses, exterior scaffolding assembly failures resulted in injuries and rescues at protected walkway areas. Materials falling or blowing off job sites onto streets and walkways, as well as mechanical and other equipment failures resulting in the collapse of building components onto vehicles and roadways, create situations requiring special attention for the incident stabilization and rescue.

    Unique challenges to fire control are presented by exposure concerns and hazards at building construction sites. Depending on the construction stage and area(s) of fire involvement, materials present and construction type, the exposure concerns could be negligible to major. A job site consisting of three-story, wood-frame apartment units could create serious exposure concerns due to flying brands, rapid flame spread and fire intensity toward surrounding exposures, which include additional framed units under construction, construction equipment and fire apparatus, as well as adjacent structures and occupancies.

    When such exposure concerns become evident, rapid deployment of additional response companies and resources should be communicated as quickly as possible. Often when the problem becomes evident, it may be too late to gain offensive fire control. Based on incident considerations, areas should be written off defensively, with protective measures deployed effectively to get ahead of the situation.

    The complexities and hazards and assessment factors present at building and construction sites become the focus when a company is dispatched to an on-site incident. Each construction stage represents a milestone in the process that, when coupled with respective safety considerations, can give an incident commander or company officer insight into the risk potential present at the job site. The stages are represented by percent of completion of the project or structure. The stages overlap, as do some of the safety conditions and hazards.

    Start up/mobilization to 15 percent Stage
    Initial project start up is underway. At a jobsite involving new construction, site work is taking place and excavation, trench and subsurface work is in progress. Temporary roadways, usually consisting of exposed earth with gravel topping, are compacted. Adjacent utilities are tapped into with temporary on-site services. Construction equipment is mobilized or brought on site. Materials, components and equipment are stockpiled and stored. Temporary storage buildings are constructed and makeshift offices and rest areas for workers are built. Construction work includes laying the foundation, formwork placement and support structuring.

    Risk potential is greatest when dealing with the stored/stockpiled equipment and materials and site considerations that affect emergency access and response and construction worker safety. Site accessibility may be hindered by excavation areas, site trenches and pits, construction worker vehicles and construction equipment, as well as temporary fencing and barricades.
    Weather conditions may play a critical role in response access with temporary roadways and site areas affected by rain, snow, thawing and mud. Companies should determine, through site inspection and preplanning, designated entry gates to site areas, alternate access roads or areas to project locations and use of heavy construction equipment for accessibility.

    Many times, response maps may not have information available for effective and accurate response. Coordination between local building officials and fire department commanders is a must. Incomplete connections, closed valves and inadequate water pressure can create water supply problems with on-site systems. Unknown or nonexistent hydrant locations may make it necessary to preplan alternate water sources. Additionally, during initial size up and incident assessment , take into account possible time delays for long and multiple hoselays.

    Trench cave-ins, excavation collapses, shoring and framework failures present challenges to even the largest agency. Undertake pre-incident training to ensure safe and effective rescue operations. In response districts or divisions where extensive, ongoing construction is present, consider securing adequate trench/cave-in rescue equipment, material and tools and develop a company with trained personnel.

    In the rehabilitation, renovation or conversion stages, interior and exterior finishes and materials may be in the process of removal or alteration. Interior partitions may be partially removed, with materials stockpiled and staged at various areas. This stockpiling, with its high fire loading, presents a potential hazard. A fire in a 52-story office building gutted the entire fourteenth floor of the structure, where building materials had been stocked for a renovation project. Interior floor and wall partition removal creates serious deficiencies in the compartmentalization capabilities of the areas, as well as allowing for avenues of fire travel both vertically and horizontally.

    The 30 to 60 percent Stage.
    This is the phase in which the structure begins to evolve into its designed form. The framing systems used rise up with materials being bolted, cast or framed in place. Skeletal steel frames are built up and the structure is fastened together temporarily to allow for the positioning of additional members. Inadequate or incomplete connection points could be affected by weather and environmental conditions, causing the structure to fail and collapse. The dead load of the material itself may shear connecting bolts. Unprotected steel columns and beams are affected by fire and heat exposure from even a small rubbish fire which, in turn, may cause the member to buckle, expand and collapse. Some steel framing may rely on cold-drawn steel cables to provide tension on the frame elements until the exterior skin is applied. These cables can fail at temperatures as low as 500 degrees Fahrenheit, precipitating a collapse.

    Exposed cast-in-place, as well as precast concrete construction, also can be affected by fire and heat exposure. The connection points may fail at a faster rate than that of the material itself, due to the smaller mass of the connecting components. Additionally, the outer layers of concrete can break away when exposed to fire and hear. This action, called spalling, occurs when the moisture content within the concrete is drawn out due to extreme heat conditions. There are two types of spalling. The first is an explosive kind that blows the material in large components away from the members, causing the pieces to be propelled outward toward operating companies, often accompanied by a loud noise. The second type of spalling is a dropping off or flaking action in which the spalling falls from the components with little force. Regardless of the action type, the size of the spall material may be such that crushing injuries are sustained.

    <
    p>
    Since both precast and cast-in-place concrete rely on steel reinforcement for its tensile strength capabilities (the concrete itself provides the compressive strength), spalling actions cause the embedded steel “rebars” to be exposed to the heating and expansion action of heat and fire conditions. This can cause the materials to separate, loosening the bonding action and causing a collapse. Additionally, concrete when applied in a cast-in-place application – where the concrete relies on formwork that is held in place by adjustable steel column rods, wood shoring and bracing – creates an extremely high fire load factor.

    Typically, concrete requires a 28-day cycle to cure to reach its compressive its design strength. Any fire conditions encountered within these formwork and shored floor areas should be treated as conditions in which the concrete is assumed to be “green” or freshly poured. No immediate fire suppression activities should be attempted within these floor areas because of the likelihood of collapse.

    In wood -frame structures, again, the main concern can be toward fire suppression capabilities due to the fire loading of the materials present, as well as the surface-to-mass ratio as a result of exposed framing present. Be aware that rapid fire spread within single structures and to adjoining structures can occur.

    As the structural framing is completed, the exterior skin or building envelope is applied. Windows and doors are fastened, interior partitions are framed and open floor areas begin to become compartmentalized. The mechanical, electrical and service systems begin to be put in place. During the 30 to 90 percent construction phases, there are still numerous conditions that contribute to fire.

    According to NFPA studies as referenced within the NFPA 24 Standard, 60 percent of the fires occurring in buildings undergoing construction, alteration or demolition originates from three specific causes:

    • Salamanders or portable heating equipment (25 percent)
    • Cutting, welding and plumbers’ torch operations (20 percent)
    • Matches and smoking (15 percent)

    During construction phase operations in adverse and cold climates, the use of portable heating devices and salamanders, along with heavy tarps and reinforced plastic sheeting cover the building to maintain a minimum temperature, is common.

    Scaffolding around the perimeter of the building may be covered, allowing no visible indication of building type, materials or alarm response conditions upon the arrival of a company. The heating devices usually fueled by LPG tanks pose dangers because of valve and tank malfunctions, contact with combustible and exposure to fire areas during suppression operations. BLEVEs are common with construction site fires and must be considered when mounting an attack.

    The 60 to 90 percent stage.
    The conditions and hazards present within the 30 to 90 percent phase can be addressed in similar fashion. During this phase, rooms, floors and other areas are undergoing completion with more finish work done with fewer trade personnel.

    During the early 60 to 75 percent stages, conditions still exist requiring full awareness of interior mobility, access and operations. There may be floor areas that still are incomplete or unprotected. Drop-offs and walk-offs may be present at any number of locations. Open shaft-ways, hoist ways, mechanical chase areas and stairwells may exist in uncompleted stages.
    As in the previous 30 to 60 percent stage, floor obstructions, pipe stubs and capped-off services may exist. Firefighters should use personal lighting to detect whether walkway areas are clear and safe. Extreme care must be taken during the night and in smoky conditions to be certain of floor area integrity.

    There are many times that shaftways and chase wells extending through multiple floors are covered temporarily with plywood. Although they may support a worker passing over them, they may not support a fully outfitted firefighter with SCBA and tools. Inadequate lighting conditions may exist throughout the complex and site, with many exposed electrical lines, conduits and power panels. Exposed wiring coming into contact with exposed steel framing and tools can energize a large area, endangering personnel in the immediate area.

    As additional systems are put in place, such as HVAC duct work, plumbing and electrical lines, additional wall areas may be penetrated. Fires originating on one level or area may travel quickly due to convection and conduction. Built-in sprinkler systems may be inoperative due to incomplete pipe runs, closed valves, lines plugged from debris or non-capped branches.
    Fire department connections may be blocked by dumpsters or heavy construction equipment. Interior standpipes may not reach to topped-off floor areas or may have open valves, incomplete connections or non-capped branches.

    Assign manpower to valve determination if attempts at using the standpipe system prove inadequate. Many times an open valve at a lower level may be the culprit. Again, manpower allocations in these areas must be augmented by multiple-alarm and mutual-aid units early in the incident. As the finish work nears completion, stockpiles of new materials begin to form. Solvents, adhesives and flammable, combustible and toxic materials used in the finish/completion stages may be present in large quantities. Class A materials from packing, furniture and equipment boxes may be located throughout the structure.

    Site accessibility improves as more of the interior building areas are completed. Paved access areas and roadways are completed; trenches, excavations and fill have been removed or backfilled. Exterior scaffolding, begins to be removed and heavy construction equipment and cranes are taken off-site. The final stage, consisting of the move-in, may not necessarily take place when the building is completed. Move-ins, when dealing with large-scale structures or high-rises, may take place on the bottom floors while construction proceeds in upper areas.
    It is critical for the safe and effective stabilization and conclusion of any incident within these building sites to assume a greater degree of assessment and subsequent operations.

    Assessment considerations include:

    • Construction type
    • Stage of construction
    • Site conditions and accessibility
    • Exposures
    • Resources
    • Operating procedures
    • Communications

    All operations must assume the risk potential present for the deployment of manpower and equipment, with the full understanding of material, component and site condition integrity during suppression and emergency operations. The magnitude and complexity of the incident will be directly proportional to the size of the building/construction site and age of the existing building, if under renovation, and degree of construction.

    Operational conditions must be addressed during strategic and tactical incident management:

    • Degree of exposed construction
    • Degree of incomplete connections
    • Number of exposures
    • Fire loading
    • Flammable/combustible materials
    • Compressed gases and vessels
    • “Green” concrete and shored, supported areas
    • Exposed electrical and utility services
    • Unprotected openings
    • Obstructions
    • Access
    • Lighting
    • Fire protection system integrity

    The ability for a response agency to safely handle an emergency incident depends upon a set of specific operational factors that include but are not limited to:

    • Incident type
    • Size-up and Assessment Factors
    • Pre-Planning Awareness & Knowledge
    • Strong Command Presence
    • Effective Modular Incident Command Management System
    • Effective Communications
    • Mobilization/ Reflex Capabilities of Response Companies
    • Anticipate
      d & Immediate Resource Needs
    • Apparatus Deployment
    • Operational Modes
    • Exposure Concerns
    • Incident stabilization, time factors
    • Incident Control
    • Fire companies should periodically inspect the construction sites in their response districts. They can assess the risk potential present and preplan for potential incidents. Information should be transmitted to second and third-due company units in the event of a large-scale incident.
    • Serviceability of all existing fire suppression systems on-site must be ascertained. This, alone, may help control situations in a time frame where deployment, application and operation become critical.

    Never assume, but be cautious and analytical in any incident that takes you to a building or construction site. The success of any operation will be dependent upon coordination of companies, technical basis of knowledge, skills and training, and the ability to remain highly flexible, based upon the continuum of information processing, cue-based analysis and incident command management.

    Fire/EMS Safety, Health and Survival Week: Day Four: “History Repeating Events”

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

    Today is June 17th, the fourth day in the Fire/EMS Safety, Health and Survival Week. To many of you, today is unlike so many other days. Whether it’s going on or off-shift, going to your “day” job; common rituals and activities define our day and are a part of your typical schedule or routine, activities, occupation, trade, leisure or everyday jobs.

    On any given day, we expect some fairly simple and basic things; Simple and basic from a firefighter’s perspective that is. Let’s clearly put this discussion into firefighter terms and context. We hope that we have a busy day, for the most part; that the alarms and incidents allow us to practice our skills and do what we do best. Deep down inside, we also hope that we have a good “job” come in that allows us to work the job, to fight the fight and put into practice all that we train and prepare to do, we the bell hits and we are called to duty.

    Not that we hope or wish undue miss-fortune, distress or sorrow on anyone, but, IF a fire is going to happen, let it happen on my shift, my tour or while I’m at the firehouse and able to make the first-due. It’s a pretty fundamental hierarchy of need, and it’s what makes us tick at times. Because of who we are and what we do. Right?

    But today is much more than that. June 17th marks the anniversary of two significant fire service incidents that resonate with the values, doctrine and philosophy that define the principles of Fire/EMS Safety, Health and Survival Week.

    Both of these incidents resulted in firefighter line-of-duty deaths at seemingly routine fires, in relatively ordinary structures and occupancies, each with unusual building construction features and conditions that would contribute to the adverse circumstances of the incident operations, and ultimately contribute to the LODD events.

    Hotel Vendome Fire-1972
    On June 17th, 1972, a typical routine day was unfolding for the Jakes in the Boston Fire Department. At 14:35 hours, Box 1571 was received at Boston Fire Alarm Office. It would be the first of four alarms required to extinguish an intense fire at the former Hotel Vendome on Commonwealth Avenue at Dartmouth Street, City of Boston, Massachusetts. It took nearly three hours to contain the blaze. The four alarm fire required a compliment of 16 engine companies, 5 ladder companies, 2 aerial towers and 1 heavy rescue company, with all companies operating with a full complement of personnel staffing.

    Following extensive and strenuous suppression operations, the BFD commenced routine overhaul operation. Then, at 17:28 hours, without warning, all five floors of a 40 by 45 foot section southeast corner of the building collapsed, burying a ladder truck and 17 firefighters beneath a two-story pile of brick, mortar, plaster, wood and debris.

    More than any other event in the three hundred year history of the Boston Fire Department, the Vendome tragedy exemplifies the risk intrinsic to the firefighting profession and the accompanying courage required in the performance of duty. Nine firefighters were killed on that day, eight more injured; eight women widowed, twenty-five children lost their fathers; a shocked city mourned before the sympathetic eyes of the entire nation.

    The Hotel Vendome fire and the Nine Line-of-duty deaths, two Company Officers and seven firefighters
    • Lieutenant THOMAS J. CARROLL, E-32.
    • Lieutenant JOHN E. HANBURY, JR., L-13.
    • Firefighter THOMAS W. BECKWITH, E-32.
    • Firefighter JOSEPH E. BOUCHER, JR., E-22.
    • Firefighter CHARLES E. DOLAN, L-13.
    • Firefighter JOHN E. JAMESON, E-22.
    • Firefighter RICHARD B. MAGEE, E-33.
    • Firefighter PAUL J. MURPHY, E-32.
    • Firefighter JOSEPH P. SANIUK, L-13.

    Built in 1871 and massively expanded in 1881, the Hotel Vendome was a luxury hotel located in Boston’s Back Bay, just north of Copley Square. During the 1960s, the Vendome suffered four small fires. In 1971, the year of the original building’s centennial, the Vendome was purchased. The new owners opened a restaurant called Cafe Vendome on the first floor, and began renovating the remaining hotel into condominiums and a shopping mall.

    Although the cause of the original fire was not known, the subsequent collapse was attributed to the failure of an overloaded seven-inch steel column whose support had been weakened when a new duct had been cut beneath it, exacerbated by the extra weight of water used to fight the fire on the upper floors.

    FDNY Father’s Day Fire-2001
    The relative calm of a quiet Sunday, Father’s Day, June 17th , 2001 was broken at 14:19 hours with a phone call to the FDNY Queens Central Office reporting a fire at 12-22 Astoria Blvd, in the Astoria Section of Queens, New York. For almost 80 years, the Long Island General Supply store has been a fixture in the Long Island City section of Queens serving local contractors and residents with all of their hardware needs. Unfortunately, that included propane tanks and other flammable liquids.

    Two structures were involved in this incident. Both buildings were interconnected on the first floors as well as the cellars.

    • Both structures were built prior to 1930 of ordinary (Type III) construction, and were two stories in height, each with a full cellar.
    • Building 1 measured 2035 square feet and was triangular in shape.
    • Building 2 measured 1102 square feet and was rectangular in shape.
    • Building 1 and Building 2 shared a common or party wall and were interconnected on the first floor and the cellar.Building to building access in the cellar was through a fire door. The fire door was blocked open to allow free movement between the cellars which were used for storage. The hardware stored occupied the first floor and cellars of both buildings. Building 1 had two apartments on the second floor.

    Building 2 had an office and storage space on the second floor. Note: A third uninvolved building was attached to the west side of Building 2. The flat roof system sheathing consisted of 5/8-inch plywood covered by felt paper and rubber roof membrane. The foundation was constructed out of stone and mortar. The support system was a combination of steel masonry posts/lolly columns and wooden support beams.

    FDNY Units arrived within 5 minutes of the dispatch and gave the signal for a working fire. Fire fighters were making good progress but at 14:48 hours something went terribly wrong. Witnesses on the scene report hearing a small explosion followed by a huge blast. The shock wave from the blast blew d
    own every fire fighter on the street and knocked down the exposure 1 wall onto the sidewalk, right on top of fire fighters venting the building.

    As members started sifting through the rubble, the chief ordered a second alarm followed almost immediately by a fourth alarm when a radio transmission was received from FF Brian Fahey from Rescue 4. He was in the basement under tons of collapsed material.

    “I’m trapped in the basement by the stairs. Come get me.” This was a battle cry to everyone on the scene. Every capable member frantically began removing debris to try and get to Brian and the others. The chief ordered more help. Numerous special calls were made.

    There were 144 pieces of apparatus at the scene: 46 engines, 33 ladders, 16 battalion chiefs, 2 deputy chiefs, all 5 rescues, 7 squads, and many more. In fact, with the exception of the fire boats, the JFK hose wagon, the Decon unit, and the thawing units, every type of special unit was at the scene.

    Even with the vast resources of the Department, the task took several hours. The members that were on the sidewalk were quickly recovered.
    • Fire fighters Harry Ford (R4) and John Downing (L163) were removed in traumatic arrest and brought to Elmhurst Hospital were they succumbed from their injuries.
    • Back at the scene members still were trying to get to Brian while others were trying to put out the smoky fire. The battle went through the afternoon and into the evening.
    • The fire was being fueled by some of the flammables in the building.
    • After about four hours they finally reached the basement, but again, it was too late. FDNY Firefighter Brian died in the Line-of-duty.

    Subsequent investigations revealed that two local kids were in the rear yard of the building when unbeknownst to them they knocked over a can of gasoline. The gasoline ran under the rear door, into the basement eventually finding an ignition source in the form of the water heater.

    When the water heater kicked in, it ignited the gasoline. As fire fighters began working in the building the fire caused the explosion of a large propane tank illegally stored in the basement. The resulting blast leveled the building and caused what will be forever known as the worst Father’s Day in FDNY’s history. (Excerpt of the event description published in www.fdnewyork.com).

    The supreme sacrifice was made that day by;
    • FDNY Firefighter Harry S. Ford, Rescue Co.4
    • FDNY Firefighter Brain D. Fahey, Rescue Co. 4
    • FDNY Firefighter John Downing, Ladder Co. 163

    Take the time to read the NIOSH Report, and learn the lessons from that event

    Buffalo, NY FD North Division Street Explosion, HERE, HERE and HERE

    Note: The Buffalo, NY, Fire Department experienced a similar event on December 27, 1983 in North Division Street Fire and Explosion that resulted in five firefighter line-of-duty deaths.

    As BFD firefighters arrived at the scene of a reported propane leak in a three-story radiator warehouse (Type III ordinary construction), a massive explosion occurred, killing five firefighters instantly and injuring nine others, three of them critically. The force of the blast blew BFD Ladder 5′s tiller aerial 35 feet across the street into the front yard of a dwelling. BFD Engine 1′s pumper was also blown across the street with the captain and driver pinned in the cab with burning debris all around them. Engine 32′s engine was blown up against a warehouse across a side street and covered with rubble.

    Two civilians were also killed and another 60 to 70 were injured. While operating at the rescue effort, another 19 firefighters were injured. The blast and ensuing fire ignited 14 residences and damaged as many as 130 buildings over a four block area. The explosion occurred when an employee was moving an illegal 500-lb. propane tank with a forklift truck and dropped it, breaking off a valve. The gas leaked out, found an ignition source, and the explosion occurred. Killed in the line of duty were all assigned to Buffalo FD Ladder Company 5; F/F Michael Austin, F/F Michael Catanzaro, F/F Matthew Colpoys, F/F James Lickfield and F/F Anthony Waszkielewicz.

    Taking it to the Streets
    The adage that the fire service has more recently adopted states; “There are no “routine calls”; referring to the safety consciousness that all responding companies should endeavor to consider when responding to an incident, that all too often appears; upon our arrival to be routine in every sense of the word. Whether it’s an alarm system activation, a report of food on the stove, a report of a smoke detector alarming or a report of a gas odor or leak, we have a tendency to treat a lot of things as equal and very routine based upon the periodicity and frequency of the alarm type and the typical, inconsequential nature of the incident outcome or the commonality of the fire and suppression efforts that routinely are employed by our operating companies.

    We seem to do a lot of things at times out of common practice and repetition, you know; “We’ve always done it that way…” syndrome. There’s a resonating theme that is making its way around the fire service dealing with an apparent “culture of extinguishment” and the suggested and inaccurately described “diametrically opposing” fire service safety culture promoted by those on the “Dark Side”

    The daily experience, expectations, our comfort zone;
    • We’re pretty good at what we do-Regularly….
    • We develop profound habits and methods…
    • We treat a lot of things as equal in many respects…
    • We’ve grown accustomed to certain operational modes..
    • We don’t really think anything is going to happen to us, certainly nothing so adverse that I don’t go home after the call.

    Nothing is going to happen to YOU; it happens to someone else….
    BUT to everyone else-YOU are the other Guy!

    On any give day, at any give alarm, the dynamics around us at times may be in or out of our direct control. We may not be able to see what the cards have in store for us, BUT we must ensure we use every fragment of training, fortitude, knowledge, skills, courage, bravery, insights, luck and sometimes (other divine) intervention to get us through.

    Take the time today or this evening to visit and download selective reports from the NIOSH Fire Fighter Fatality Investigation and Prevention Program. The lessons learned from these reports and the important recommendations that are written as a direct result of the supreme sacrifices made by our brother and sister firefighters that died in the line of duty speaks volumes. In reality, the words written in these reports are the words from our fallen, they convey the messages to correct deficiencies, close gaps and increase and enhance are
    as of operations, training, education, administration, management, supervision, resources, equipment, protocols, preparedness, perspectives, culture and values.

    When you look over these events over the years, it doesn’t take long to identify that many LODD events share similarities, and that specific incident events, deficiencies, outcomes and recommendations are identical in every way, except for the fire department name and geographical location. In other words, we have History Repeating Events (HRE). Events that resonate with common issues, apparent and contributing causes and operational factors that share legacy issues that the fire service fails to identify, relate to and implement. In other words, we fail a times to learn from the past, or we make a deliberate chose to ignore those lessons due to other internal or external influences, pressures, authority, beliefs, values or viewpoints. We make choices and we determine our direction, path and destiny.

    History repeating itself is nothing new to society, it is apparent and self revealing in much of written history and recorded legacies, and as defined by a popular quote states; “Those who cannot learn from history are doomed to repeat it.”

    An interesting series of quotes from noted historian Gerda Lerner states the following;
    “What we do about history matters. The often repeated saying that those who forget the lessons of history are doomed to repeat them has a lot of truth in it. But what are ‘the lessons of history’? The very attempt at definition furnishes ground for new conflicts. History is not a recipe book; past events are never replicated in the present in quite the same way. Historical events are infinitely variable and their interpretations are a constantly shifting process. There are no certainties to be found in the past.”

    She goes on to state; “We can learn from history how past generations thought and acted, how they responded to the demands of their time and how they solved their problems. We can learn by analogy, not by example, for our circumstances will always be different than theirs were. The main thing history can teach us is that human actions have consequences and that certain choices, once made, cannot be undone. They foreclose the possibility of making other choices and thus they determine future events.”

    We must learn for the part, so that we limit or eradicate the opportunity for History Repeating events aligning themselves again and providing emergency incident circumstances to lead to another line-of-duty death, injuries or large loss incident.

    History Repeating Events share may common and familiar themes. Research exemplifies the following shared commonality causes related to History Repeating Events;
    • A lack of pre-incident planning
    • Ineffective or lack of risk management
    • No Incident action plan• Free-lancing
    • Inadequate Training/Skills• Faulted Strategies and/or Tactics
    • Deficient Resources/staffing
    • Lack of Accountability• Insufficient Fire Suppression versus Fire Loading affect• Ineffective or non-existent Supervisory oversight
    • No effective span of control / management
    • Not understanding Building Construction
    • Not understanding Structural Assemblies and Systems
    • Not understanding Construction & Occupancy factors• Not understanding Engineered Building Systems and relationship to Tactics
    • Lacking understanding of Fire Behavior and Fire Dynamics
    • Ineffective Company level supervision
    • Lack of Situational Awareness• Command Dysfunction
    • Failure to implement periodic in-situ reassessments

    Think about your actions, think about what you can do to make a difference or to alter or change the course of a situation. We sometimes have a greater hand in destiny and how the cards are dealt than we think. Take a look and discuss the HRE causal factors listed above, share these with you officers, with you company level personnel or the department as a whole. Pose the question, “What do these mean to you?” See what the different feedback might illustrate and how they may be viewed from a different set of perspectives, generations or rank and assignments.

    Fire/EMS Safety, Health and Survival Week: Day Two. “Building Knowledge = Firefighter Safety”, Know Your District and its Risk

    2 comments

    Fire/EMS Safety, Health and Survival Week: Day Two. “Building Knowledge = Firefighter Safety”, Know Your District and its RiskProtect Yourself: Your Safety, Health and Survival Are Your Responsibility. There are Four (4) Key Focus areas in this year’s Fire/EMS Safety, Health and Survival Week, which include Safety, Health, Survival and Chiefs. Within the focus area of Survival and the elements of Structural Size-Up and Situational Awareness, a specific key functional component is;

    •Keep apprised of different types of building materials and construction used in your community.
    •The operative question today is this: “What do you “really” know about the buildings in your district?”

    As you drive about your response district today, coming back from an alarm, heading to the firehouse tonight or running errands around your community, take a good look around. Ask your self a simple question; “How well do you know the buildings, structures and occupancies in your response jurisdiction?”

    •Be honest, do you really understand how those “older residential” structures were built and understand how fire travels and impacts your fireground operations?
    •Are your aware of the newest features of engineered structural support systems being constructed within that new set of homes going up in your second-due area?
    •Are you aware, that vacant office building is being converted into a light manufacturing and assembly business?
    •How about those unoccupied store fronts and businesses that have recently closed up due to the tough economic times…. any special hazards or operational concerns to your company should you get a dispatch to respond?
    •Have the senior members of your station or department shared their stories of operations and incidents at various buildings around your district or community?
    •Did you listen to them, or were you quick to dismiss those “old war stories”. There’s a wealth of “pre-planning’ nuggets hidden in those stories. Take the time to listen, remember or postulate.

    Take a good look around….think about any given building, the one across the street that you’re looking at while you waited for the traffic light to change; Think about a fire in that same building.

    •Do you really understand how it will truly perform under combat structural fire conditions?
    •What’s the building’s collapse profile?
    •How much operational time will you have?
    •What dynamic risk assessment factors will you have to deal with?
    •How safe is it for you to engage in interior operations upon your arrival?
    •How can this building, its occupancy and structural system hurt, my team, my company, my firefighters, my department, me?

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

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

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

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

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

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

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

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

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

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

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

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

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

    •Attached is a copy of the Tempe, AZ Fire Department Pre-Incident Planning SOP
    •The Phoenix, AZ Fire Department Pre-Incident Planning SOP is available HERE
    •An informative Pre-Fire Planning article by Battalion Chief Michael Lee is available HERE

    Spend time touring through construction sites as you monitor the progress of a building or occupancy going up. Look at the manner in which structural support systems are fabricated and assembled. Observe the types of materials that are being used and how they are assembled to form rooms and compartments within the structure.

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

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

    •Keep apprised of different types of building materials and construction used in your community.
    •Document those conditions and aspects and train your personnel to understand the occupancies within your community.

    •Understand the Structural AnatomyTM of your buildings and occupancies.
    •The operative response to the opening question this time next year will be this: “What do you “really” know about the buildings in your district?” …The answer will hopefully be…”A lot!”

    •Here’s my New Safety Formula; Bk = f2S, Building Knowledge = Firefighter Safety

    Engineered Lumber ID Program: Enhancing Firefighter Safety, One Step at a Time

    No comments

    The City of Greencastle, Indiana and the Greencastle Fire Department recently enacted and approved an Engineered Lumber ID Program consisting of a sticker that is used for quick recognization of potential Collapse Dangers associated with Engineered Lumber constructed buildings. The sticker is placed on every electrical meter of all residential & commercial buildings with Engineered Lumber construction built after May 13th 2008.

    The news release states that; the use of this type of lumber in building construction presents a great danger to firefighting personnel when those structures are involved in fire conditions. By design, the Engineered Lumber in floor and roof assemblies will collapse, without warning, after being exposed to heat or flame contact for a very short period of time.
    Because of the inherent danger firefighters must face while operating within these buildings, an Engineered Lumber Identification Program (ELIP) has been instituted to alert personnel of the danger prior to beginning fire suppression operations.

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

    WHEREAS, many new building structures currently use engineered lumber in their construction;
    WHEREAS, some types of engineered lumber burn at a rate faster that other types of lumber; and
    WHEREAS, in fighting fires, it would be helpful to know the types of materials used in the construction of a structure.

    NOW THEREFORE be it ordained by the Common Council of the City of Greencastle as follows:
    1. Definitions:
    a. Engineered Lumber shall mean prefabricated I-joists, truss joists, and truss rafters, and laminated beams and studs.
    b. Structure shall mean primary, secondary and accessory structures as defined in the Greencastle Zoning Code that have electrical meters that serve the structure.
    2. All structures constructed with engineered lumber after the effective date of this ordinance must have a reflective symbol affixed to each electrical meter serving the structure.
    3. The reflective symbol shall be in the form of a sticker, issued by the City of Greencastle that states that the structure is constructed with engineered lumber
    4. Any person violating this ordinance by refusing to use the reflective symbol or by removing the reflective symbol shall be subject to a fine in an amount of $25.00 per violation. Each day that a violation occurs shall constitute a separate violation, subject to a separate fine.
    5. The owner of any structure that was constructed with engineered lumber prior to the effective date of this ordinance is requested to place the reflective symbol on the electrical meter serving the structure on a voluntary basis.

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

    Take a Good Look Around-This is Your Town

    No comments

    As you drive about your response district today, coming back from an alarm, heading to the firehouse tonight or running errands around your community this weekend, take a good look around.

    Ask your self a simple question; “How well do you know the buildings, structures and occupancies in your response jurisdiction?”Be honest, do you really understand how those “older residential” structures were built and understand how fire travels and impacts your fireground operations?

    Are your aware of the newest features of engineered structural support systems being constructed within that new set of homes going up in your second-due area? Are you aware, that vacant office building is being converted into a light manufacturing and assembly business?

    How about those unoccupied store fronts and businesses that have recently closed up due to the tough economic times…. any special hazards or operational concerns to your company should you get a dispatch to respond?

    Have the senior members of your station or department shared their stories of operations and incidents at various buildings around your district or community? Did you listen to them, or were you quick to dismiss those “old war stories”.

    There’s a wealth of “pre-planning’ nuggets hidden in those stories. Take the time to listen, remember or postulate.Take a good look around….think about any given building, the one across the street that you’re looking at while you wait for the traffic light to change; Think about a fire in that same building.

    Do you really understand how it will truly perform under combat structural fire conditions? What’s the building’s collapse profile, how much operational time will you have, what dynamic risk assessment factors will you have to deal with, how safe is it for you to engage in interior operations upon your arrival? How can this building, its occupancy and structural system hurt, my team, my company, my firefighters, my department, me?Sometimes things aren’t as obvious as them seem.

    You may have responded and operated at numerous incidents at a wide variety of buildings in your response area, or very few; some routine, others maybe more demanding…the question remains, “What do you Really know about your buildings?” Your life may one day depend on what you actually do know or recollect. Take a good look around ….

    BECOME SAFE

    No comments

    Can the Command and Company Officer truly make a difference in the outcome
    during structural fire combat?
    If they can make a difference – what tools are required to succeed?
    What are the relationships to; Knowledge, Experience, Technical skills, Proficiency, Core values, Depth and degree of separation, Maturity and stability, Cue-based mastery, Learning curves, Variables of liabilities, Community-based risks…
    There are basic sets of parameters that can provide all operating personnel at structural fire operations with effective tools to increase operational effectiveness, safety and enhance incident stability and lead the forward progress towards event mitigation.
    This includes the effective integration of BECOME SAFE (Naum, 2004) concepts;
    Building,
    Evaluation,
    Construction/occupancy,
    Operational hazards,
    Manage time and elements,
    Engagement,
    Situational awareness,
    Assessment and dynamic analysis,
    Fire behavior and effects,
    Evaluate and execute
    The best defense firefighters have against building collapse is to understand the principles of building construction and the effects that fire has on a building; then apply this information on the fireground. Sometimes collapse indicators are evident in the initial size-up, but more often they are discovered by members operating in and around the fire building.
