Fire behaviour can be understood and predicted if you are familiar with the elements of fire. Fire is a chemical reaction that requires three elements to be present for the reaction to take place and continue. The three elements are:
- Heat or an ignition source
- Fuel source
The ignition source can include a material, equipment or operation that emits a flame, spark or radiates heat such as torches, grinding operations and kettles.
Fuel sources include combustible materials such as wood and paper; flammable liquids and gases such as solvents, and propane.
These elements must combine in a precise way for a fire to start and continue to burn. If one of these elements is not present, a fire will not start or if already burning will extinguish.
