A sudden backward flare or burst of flame; in technical contexts, a sudden reverse surge of fire or explosive reaction.
Compound of 'flare' (a sudden burst of bright light or flame) and 'back' (backward direction). This technical term combines two words to describe a specific directional phenomenon in fire or explosion dynamics.
Flareback is a dangerous phenomenon in industrial settings and firefighting where heat suddenly pushes flames backward unexpectedly, which is why firefighters must maintain spatial awareness during rescue operations.
