fire SAFETYFire is a rapid chemical reaction of oxidant with fuel accompanied by the release of energy, indicated by incandescence or TetrahedronHeatFuelChain ReactionOxidiserFor a fire to happen, the following elements are essential Oxidiserto sustain combustion. Heat to reach ignition temperature. Fuelor combustible results in a chemical chain reaction which starts a any of these elements will extinguish the CharactersiticsDuring a fire heat transfer occurs by Conduction-transfer of heat within the material itself. Convection -transfer of heat by the physical movement of hot masses of air. Radiation -refers to the emission of heat in the form of electromagnetic Transfer Ignitionis the process of initiating self sustained combustion.
For a fire to happen, the following elements are essential • • Oxidiser to sustain combustion. • Heat to reach ignition temperature. • Fuel or combustible material. This results in a chemical chain reaction which starts a fire. Removing any of these elements will extinguish the fire.
