WHAT IS FIRE?

Fire is a chemical reaction known as combustion which occurs when fuel and oxygen are brought together with sufficient heat to cause ignition.

You need three things to start a fire: Heat + Oxygen + Fuel = Fire

This is also known as the triangle of fire.

Heat - A critical temperature must be reached - a heat source

Fuel - The combustible substance - something to burn

Oxygen - Completes the combustion cycle

Keep them all separate and a fire will not start. Removing any one of them stops the fire.
