Backdrafts are typically seen as a blast of smoke and/or flame out of an opening of a building. Backdrafts present a serious threat to [[firefighter]]s.  There is some debate concerning whether backdrafts should be considered a type of [[flashover]].

Eventually, the air mixes with the hydrogen inside the container, causing an explosion. A similar process occurs during a backdraft, with the introduction of oxygen and mixing with unburnt gases causing abrupt or even explosive combustion]]
