Reviewed by a licensed fire protection specialist Short answer: Fire requires four elements — fuel, oxygen, heat, and a self-sustaining chemical chain reaction (the fire tetrahedron). Every suppression method works by removing one element: water cools fuel (removes heat), foam smothers surface (removes oxygen), dry chemical interrupts molecular chain reaction.
