1 st Stage: Incipient 1 st stage No visible flame Little smoke Is not yet self-sustaining According to the National Fire Protection Association, fires in this stage can be controlled with a fire extinguisher.

2 nd stage: Growth Self-sustaining Heat of flame ignites more fuel Size of fire increases, flames reach ceiling Hot gases spread across the room and raise everything within the room closer to ignition temperature at the same time. Flashover may occur

Flashover

Last Two Stages: Fully Involved and Decay Fully Involved Everything in the room has reached its ignition temperature and is burning Decay Longest stage
