Flashcards
Ignition
Ignition
The initial stage of fire where the four elements of the fire tetrahedron (heat, fuel, oxygen, and a chemical chain reaction) combine to initiate combustion.
Growth
Growth
The stage after ignition where the fire plume begins to form, and the fire spreads to engulf more surrounding space.
Flashover
Flashover
The transition between fire stages where all combustible material in the compartment is involved. It signals the point where the fire becomes most dangerous.
