Abstract:

On March 28, 1994, the New York City Fire Department responded to a report of smoke and sparks issuing from a chimney of a three-story apartment building in Manhattan. The officer in charge ordered three-person hose teams to enter the first- and second-floor apartments while the truck company ventilated the stairway from the roof. When the door to the first-floor apartment was forced open, a large flame shot out of the apartment and up the stairway, engulfing three fire fighters on the second-floor landing. The flame lasted for at least 6 1/2 minutes, killing the three men. In the hope of understanding the factors that produced a backdraft of such duration, the fire department asked the National Institute of Standards and Technology (NIST) to model the incident.
