A series of fire tests were conducted to characterize the potential hazard from ignition of an upholstered chair. The particular chair was selected as part of a fire investigation being conducted by the U.S. Department of Treasury’s Bureau of Alcohol, Tobacco, and Firearms.
Heat release rate was determined as a function of time from ignition using the oxygen depletion principle. Two tests were conducted with the chairs placed in the open under large calorimeters.
The third test was conducted with the chair located in a room. Peak heat release rates obtained during the tests ranged from approximately 1 MW to 2.5 MW.
