Flashover
fire changes from one that is dominated by the burning of the materials first ignited to one that involves all of the exposed combustible surfaces within the compartment
Flashover
gases generated during this time are heated to their ignition temperature by the radiant energy from the gas layer at the ceiling
Flashover
Fire grows in a compartment, large volumes of hot unburned fire gases can collect in unventilated spaces. These gases may be at or above their ignition temperature but have insufficient oxygen available to actually ignited
Backdraft
Pressurized smoke exiting small openings, black smoke becoming dense gray yellow, confinement and excessive heat, little to no visible flame, smoke leaving the building in puffs or at intervals (appearance of breathing), smoke-stained windows
