The Waldbaum’s Supermarket Fire and Collapse: FDNY 1978-2019 41st Anniversary
Honor, Remembrance, Learning’s
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 24 firefighters were on the roof when the central portion gave way. A 4,000-square-foot area opened and erupted into intense fire. Twelve firefighters were swallowed into the fire: From Ladder 156, Cutillo, Bouton, O’Connor, Campbell (detailed from Ladder 153) and King; from Ladder 153, McManus and Rice; from Rescue 2, Vallebuona; from Ladder 169, Madigan and Plaut; from Battalion 42, Hastings; and from Engine 246, Firefighter William Kelly.

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.
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 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.Located at the corner of Ocean Avenue and Avenue Y, Waldbaum’s Supermarket was a one-story taxpayer, 100 x 150 feet in size. There was a one-story extension on the exposure 4 side that was being constructed. The main store had a mezzanine that was used for office space and a compressor room for the air conditioning.
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 roof was supported by seven 100-foot-long heavy timber bowstring trusses spaced 20 feet apart, and each measured 10-foot, 1-inch high from the top chord to the bottom chord at the apex of the truss. There were sloping hip rafters that connected the first truss and the last truss to the front and rear walls. The trusses were numbered front to rear. All the even-numbered trusses, which were covered with sheetrock, had a doorway so that workers could pass back and forth within the trusses. The characteristic curved roof shape that would indicate a bowstring truss roof support system was not visible from the street.
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.
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 completed 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. More on the Hackensack Ford Fire HERE.

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.
Make time to honor and share remembrance for these brave brother firefighters from FDNY who made the supreme sacrifice and the Lessons from the Fireground that resonate clearly today.
Lessons from the Fireground: BUILDING KNOWLEDGE = FIREFIGHTER SAFETY
