The 701 University Ave Fire- 1978

 

Fire in Syracuse: Four firefighters LODD: The 701 University Avenue Fire April 9, 1978

April 9th marks the 35th anniversary of the 701 University Ave. fire that claimed the lives of four Syracuse (NY) firefighters in 1978 while conducting search & rescue and suppression operations at an apartment building on the Syracuse University Campus, in Syracuse, New York.  

 

The fire began when one of the tenants lit a candle in a styrofoam wig stand and left it unattended. At 00:46 hours on Sunday April 9, 1978, an alarm of fire was transmitted for a reported building fire at 701 University Avenue on the campus of Syracuse University.

The Victorian style house was a three story building constructed of wood balloon framing and was built circa 1898. The house had been converted into ten (10) apartments that were occupied by SU students. The gross area of each of the three floors was approx. 1,750 sq. ft., with a predominate rectangular footprint shape measuring 69 ft. x 35 ft.  The third floor apartments only had access via a stairway in the rear, down a long narrow corridor that measured only 33 inches wide.

The building had inherent vertical and horizontal concealed spaces indicative of balloon frame style construction along with additional concealed spaces in the third floor ceiling area. A partial automatic sprinkler system had been installed in the building in order to comply with a 1952 State of New York law. This system provided protection to the basement, means of egress, a storage area and a portion of the concealed space above the third floor.

The fire originated in a second floor apartment, and then spread into the combustible concealed space above the third floor ceiling. Approximately sixteen minutes into fireground operations the first indications of firefighting personnel being in distress were received.  The first call to the Alarm center was made at 0045:17 hrs., with the first-due engine arriving at 0048:05 and first water applied at 0051 (est).

 

The four SFD fire fighters, Frank Porpiglio Jr., Stanley Duda, Michael Petragnani, and Robert Schuler, who were assigned to the Squad and Rescue Companies, entered the house to conduct a primary search of the premises for SU students thought to be trapped in the house.

While operating on the third floor inside, a scalding steam caused by triggered sprinklers prevented the four firefighters from escaping, and they eventually depleted their air supply and suffocated to death. The firefighters were operating with full PPE that was complaint at that time ( 1978) and were utilizing state-of-the art SCBA in the form of the new 4.5 SCBA systems.   All the tenants had escaped safely before the fire fighters had entered the house. The fire was subsequently investigated by the National Fire Protection Association (NFPA) at the request of the City of Syracuse and NFPA Report No. LS-3 was published.

Gypsum Board Ceiling Systems, Ceiling Collapse and Firefighter Safety

No comments

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

Included in that reporting was expanded information on gypsum wall board ceiling systems. If you don't know about the National Fire Fighter's Near-Miss Reporting System and the Report of the Week (ROTW) follow these links HERE , HERE and HERE. More importantly, get involved and post some of your current OR past near-miss experiences and close calls, so the fire service can learn and everyone can go home. www.firefighternearmiss.com. Check out the extensive resources and materials avaiable on the site to support your training and operational needs.

Near-Miss Report of the Week

From the NMRS & ROTW;

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

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

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

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

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

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

Gypsum Board Ceiling Systems and Firefigher Safety

 

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

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

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

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




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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Multi-Layer Application

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

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

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

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

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

The Waldbaum’s Supermarket Fire and Collapse FDNY 1978 - 2011

The Waldbaum Super market fire, Brooklyn, New York occurred on August 2, 1978. Six firefighters died in the line of duty when the roof of a burning Brooklyn supermarket collapsed, plunging 12 firefighters into the flames. The fire began in a hallway near the compressor room as crews were renovating the store, and quickly escalated to a fourth-alarm. Less than an hour after the fire was first reported, nearly 20 firefighters were on the roof when the central portion gave way. 

The FDNY members killed in the Waldbaum’s fire included:
• Lt. James E. Cutillo, Battalion 33
• Firefighter Charles S. Bouton, Ladder Company 156
• Firefighter Harold F. Hastings, Battalion 42
• Firefighter James P. McManus, Ladder Company 153

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.

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.

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;

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.

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

3 comments

Fire Service Tradition and The Brotherhood

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

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

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

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

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

History Repeating Events-Integrate into your Training

 

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

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

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

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

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

What are we Learning? What are we Applying?

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

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

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

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

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

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

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

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

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

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

No comments

Roof Collapse Chesapeake VA 1996 Double LODD

OVERVIEW

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

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

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

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

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

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

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

City of Chesapeake (VA) Truss ID Program, HERE

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

 

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.

Gypsum Board Ceiling Systems and Firefigher Safety

1 comment

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

The importance of maintaining heightened situational awareness, identifying and monitoring suspected or inherent building construction hazards coupled with inherent occupancy risk factors, and aligning those with strategic objectives, incident actions plans and tactical deployment operations. Building Knowledge equating to firefighter safety is still a driving principle that is formulative to all firefighting operations in buildings, occupancies and structures. Let’s take this opportunity to gain some insights into the material that compromises nearly all wall and ceiling membrane systems and assemblies in nearly all buildings, occupancies and structures; that is gypsum board components. I’ve included a number of video clips that center on our discussion, as the videos center on the operation parameters at this extremely large (floor area/square footage) residential occupancy. Most clips have good coverage of the structure and firefighting efforts. Take a few moments to review these clips before you proceed;

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

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

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

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

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

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

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

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

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

 
    

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

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

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

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

     

    

    

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

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

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

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

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

   

   

    

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

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

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

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

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

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

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

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

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

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

Multi-Layer Application  

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

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

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

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

  

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

The Waldbaum’s Supermarket Fire and Collapse FDNY 1978  

The Waldbaum Super market fire, Brooklyn, New York occurred on August 2, 1978. Six firefighters died in the line of duty when the roof of a burning Brooklyn supermarket collapsed, plunging 12 firefighters into the flames. The fire began in a hallway near the compressor room as crews were renovating the store, and quickly escalated to a fourth-alarm. Less than an hour after the fire was first reported, nearly 20 firefighters were on the roof when the central portion gave way.  

  

Thirty-four firefighters, one emergency medical technician and one Emergency Services police officer were injured in the fire and the tragedy is remembered as one of the worst disasters in the New York City Fire Department’s 143-year history.  

The FDNY members killed in the Waldbaum’s fire included:
• Lt. James E. Cutillo, Battalion 33
• Firefighter Charles S. Bouton, Ladder Company 156
• Firefighter Harold F. Hastings, Battalion 42
• Firefighter James P. McManus, Ladder Company 153
• Firefighter William O’Connor, Ladder Company 156
• Firefighter George S. Rice, Ladder Company 153 

The fire started at 8:40 am in Waldbaum’s supermarket located at 2892  Avenue Y and Ocean Avenue in the Sheepshead Bay section of Brooklyn. Nearly 23 electricians, plumbers and contractors were renovating the building when the fire was discovered in mezzanine area. Box 3300 was transmitted at 08:39 hours and the All hands transmitted at 08:49 and subsequently a 2nd alarm at 09:02 hrs. Shortly after 09:20 with 20 firefighters operating on the bowstring truss roof a crackling sound was heard and the center portion of the roof fell into the smoke and flames. Some of the firefighters were seen running toward the edge of the roof; some made it, others nearby fell into the gaping hole. The third alarm was transmitted at 09:18 3rd alarm and subsequently escalated to a Fifth alarm assignment during the rescue and recovery operations.  

Roof Operations prior to collapse

 

Laborers and firefighters managed to pull out some who were near walls, some crawled out. Several holes were made into the wall to pull out injured survivors and victims.  

The Building  

The approximately 120 ft.  x 120 ft. primary building was originally built in 1952 as a supermarket and at the time of the fire was undergoing extensive renovations and was open and operating. Constructed with exterior masonry bearing walls of  with  timber roof trusses with a 100-foot clear span, supported on pilaster columns embedded in the exterior walls, it was classical Type III construction. The truss system supported an ornamental tin ceiling and 18 inches below that concealed space a conventional suspended acoustic ceiling tile panel system was present. Reports indicated the tin ceiling was attached directly to the bottom cord of the truss system.  A two story mezzanine and machine room was located at the north wall of the original building. Access through the truss loft area was accessible through man-doors at the plane of each truss.

The heavy timber bowstring arch roof consisted of seven (7) truss units constructed of 4-5 bundled 3 inch x 12 inch attached assemblies.  Two factors contributed to the collapse of the bowstring arch truss system; double roof (rain roof) alterations with concealed spaces and the extent and severity of the fire within the concealed spaces affecting the assembly’s structural stability. The presence of the double concealed ceiling systems; the truss system supported an ornamental tin ceiling and 18 inches below that concealed space a convential suspended acoustic ceiling tile panel system was present. Reports indicated the tin ceiling was attached directly to the bottom cord of the truss system. The failure of  operating companies and command personnel to recognize the signs of an unchecked concealed fire that was propagating at a rapid pace impinging upon critical structural assembly points was a significant contributing factor in the incident outcome. 

Typical Heavy Timber Bowstring Arch Truss Configuration

 

This roof collapsed 32 minutes after the initial units arrived. The immediate collapse occurred approximately 85 feet inward from the Alpha side (Ocean Avenue) and approximately 50 feet from the Bravo side (Avenue Y). The immediate failure and loss of structural stability and collapse of truss unit #5 was followed with the subsequent collapse of truss units #6 and #4 that were interdependent on the roof rafter and purlin system to maintain thier structural stability and vertical orientation. This type of interdependent structural system of structural trusses, rafters and roof deck (membrane) result in large area collapses since the primary truss will usually cause the adjacent two truss systems (on either side of the primary compromised truss) to fail by pulling downward.  

The effects of direct flame impingement on the truss assessmblies, thier connection points of bearing at the outter masonry walls, coupled with the tactical trench cut that had been comopleted by the operating ladder companies resulted in 4,000 sf section of roof to collapse in the truss #5, 6 and 4 bay areas. Rapid and progressing fire travel within the concealed spaces and the degradation of the roof assembly and structural support system, failure to recognize the inherent opertaional risks associated with roof and interior operations on heavy timber truss roof systems and the failure to correlate continued interior suppression operations with simultaneous roof ventilation operations with no significant change in operational progress or mitigation contributed to the tragic outcome of the incident.  

A short ten years would pass and the lessons from the Waldbaum Fire would soon be forgotten when on July 2, 1988 operations in a Type III building consisting of an auto dealership would lead to the deaths of five (5) Firefighters in Hackensack, New Jersey when operations were being conducted in the truss loft storage area when an 80 foot heavy timber truss collapsed trapping the firefighters. The Hackensack Ford Fire occured less than four weeks short of the tenth anniversary of the Waldbaum Fire right across the Hudson River.

The lessons learned in the years following the Walbaum’s fire in 1978 and the subsequent Hackensack Ford Fire, NJ in 1988 focused on understanding building construction systems, occupancies and structural assemblies, in both of these cases the timber bowstring truss systems. Over the years the foundation of knowledge necessary to build competencies and knowledgeable firefighters, fire officers and commanders cognizant in the science and technology of building construction has waned and at time has been less than an area of focus.  

Take the time to learn about the FDNY Walbaum’s fire, its history repeating significance as a major fire service LODD event, the lessons learned from the Hackensack Ford Fire (July 2, 1988) and other related case studies that can be found on the NIOSH, USFA and NFPA web sites.  

Look at your buildings within your response areas and jurisdiction. Understand how they’re built and more importantly how they are affected by the exposure and impingement of fire and its byproducts. Understand key building performance indicators and appropriate strategic and tactical actions based upon building profiles, occupancies, fire loading, construction features and fire service resources. Take the time to honor the brave brother firefighters from FDNY who made the supreme sacrifice thirty two years ago, and gave a legacy to learn from in this and in future fire service generations.  

It’s time to think; BUILDING KNOWLEDGE = FIREFIGHTER SAFETY
