Fire:
- Fire is the burning of combustible material.
- A fire in an unwanted place and on an unwanted occasion and in uncontrollable quantity can cause damage or destroy property and materials.
The factors that control fire:
Fuel:
- Any substance, liquid, solid, or gas will burn if given oxygen and a high enough temperature.
Heat:
- Every fuel will begin to burn at a certain temperature.
- Solids and liquids give off vapor when heated and it is this vapor which ignites.
- Some liquids give off vapor even at normal room temperature say 15° C, e.g. petrol.
Oxygen:
- Usually, it exists in sufficient quality in the air to keep a fire burning.
Extinguishing of fires:
Isolating or removing any of these factors from the combination will extinguish the fire. There are three basic ways of achieving this:
- Starving the fire of fuel by removing the fuel in the vicinity of the fire.
- Smothering, i.e. by isolating the fire from the supply of oxygen by blanketing it with foam, sand, etc.
- Cooling, i.e. by using water to lower the temperature, i.e. by removing heat.
