The flash-over refers to the phenomenon that fire suddenly causes overall combustion in a building, namely when combustible gas and insufficiently combusted gas which are formed by combustion of indoor big fire and fill each room in the room reach certain concentration, the formed deflagration causes that combustible substances which are not contacted with the big fire in other rooms in the room are ignited and combusted together, namely, the combustible substances are ignited to start combustion in the room at the sound of 'flash-over'.

The flashback refers to the rapid deflagration phenomenon which occurs when the high-temperature incomplete combustion products (flue gas) generated by the combustion of rich fuel meet fresh air. The back combustion is a phenomenon that after building fire with limited ventilation enters anoxic combustion or even smoldering, hot smoke is rapidly combusted due to sudden and large amount of supplementary fresh air, and is a special fire phenomenon. In the combustion process and in the high-temperature environment after the sintering, the indoor combustible still undergoes the pyrolysis reaction, a large amount of combustible gas gradually accumulates in the room, and once the ventilation condition is improved, air is supplemented in the form of gravity flow to be mixed with the indoor combustible gas. After the mixed gas is ignited by ash, flame propagation with high intensity and high speed can be formed, and huge fireballs are formed outside the ventilation opening while indoor combustion is carried out, so that harm is caused to the indoor and outdoor.
