A backdraft (North American English), backdraught (British English) [1] or smoke explosion is the abrupt burning of superheated gases in a fire caused when oxygen rapidly enters a hot, oxygen-depleted environment; for example, when a window or door to an enclosed space is opened or broken. Backdrafts are typically seen as a blast of smoke and ...
The term "downdraft" can also refer to a type of backdraft which occurs through chimneys which have fireplaces on the lowermost levels (such as basements) of multi-level buildings. It involves cold air coming down the chimney due to low air pressure, and makes it hard to light fires, and can push soot and carbon monoxide into domiciles.
Such an event is known as backdraft. A delayed flashover occurs when the colder gray smoke cloud ignites after congregating outside of its room of origin. This results in a volatile situation, and if the ignition occurs at the ideal mixture, the result can be a violent smoke gas explosion.
The backblast area is dangerous to ground personnel, [2] who may be burned by the gases or exposed to overpressure caused by the explosion. [3] In confined spaces, common in urban warfare , even the operators themselves may be at risk due to deflection of backblast by walls or sturdier civilian vehicles behind them.
