Origin of backdraft:
An extreme fire behavior phenomena involving ignition of products of combustion (such as carbon monoxide) and pyrolysis products upon introduction of oxygen to a compartment. In this phenomena the fuel generally is at a high temperature (above 600 degrees C), but combustion is limited by a lack of oxygen. Introduction of atmospheric oxygen results in explosive combustion.
A backdraft is an explosive event caused by a fire, resulting from rapid re-introduction of oxygen to combustion in an oxygen-depleted environment, for example, the breaking of a window or opening of a door to an enclosed space. Backdrafts present a serious threat to firefighters. There is some controversy concerning whether backdrafts should be considered a type of flashover.
