What Are The Elements That Cause Fires to Start?

Four elements are needed to create a fire: fuel, oxygen, heat, and a chemical reaction.

Fuel is any combustible material, solid, liquid or gas. Most solids or liquids become a vapor or gas before they burn. Oxygen exists in the air we breathe, which contains about 21% oxygen. A fire only needs an atmosphere of 16% oxygen.

Heat is the energy necessary to increase the temperature of the fuel to a point where sufficient vapors are given off for ignition to occur. A chemical reaction with fuel, oxygen, and heat must be present in the correct levels in order for fire to occur.

By removing any one of these four elements, a fire cannot exist, or it will be extinguished if it is already burning.
