Fire Response: How Fires Start
Fire is a chemical reaction involving rapid oxidation or burning of fuel. It needs three elements to occur:
 |
Fuel cam be any combustible material: solid, liquid or gas. Most solids and liquids become a vapor or gas before they will burn. |
 |
The air we breathe is about 21% oxygen. Fire only needs an atmosphere with at least 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. |
