Fuel can be any combustible material in any state of matter - 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 requires 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.
Flash point- The temperature at which a particular flammable liquid gives off vapors (vaporizes) and therefore can ignite.
Theignition temperatureis the temperature required for a liquid to continue to emit vapors that can sustain
Liquid materials are commonly used because of ease of ignition and familiarity of use.
Accelerants are nearly exclusively derived from hydrocarbons.
Straight chain hydrocarbons are the backbone of the oil industry.
Hydrocarbons are molecules made up of the elements hydrogen and carbon.
Octane is a term familiar to all. It consists of a hydrocarbon having 8 carbons.Accelerants
Point of Origin – Burn patterns and other damage can help determine the point of origin, or the location where the fire started.
First the point of origin is determined:
Once point of origin is determined, the cause of the fire is determined.
