Four Components:

• Fuel
• Oxidizing Agent
• Heat
• Uninhibited Chemical Reaction

NOTES

The fire tetrahedron is a four sided figure that is often used to describe the components required for flaming combustion.

The four components required for a fire are the fuel, the oxidizing agent, the heat, and an uninhibited chemical chain reaction.

For the fire to keep burning, all four sides must be present in the right combinations.

Another way of looking at this is to realize that removing any one of the four sides of the tetrahedron will extinguish the fire.

Knowing this enables us to start to explain many different aspects related to fires.

Remember we can control the fire by controlling (and importantly extinguish) the fire by controlling these four factors.
