What is Fire Triangle?

For combustion to take place three components are necessary and these form the ‘fire triangle’, removing any one of the components will prevent or extinguish a fire.The components are:
Fuel: There must be a source of fuel for any fire to take place. In most cases the fuel does not itself burn (except if
it is a gas) but breaks down under the influence of the applied or generated heat to produce combustible volatiles
that are then burnt. This is important in terms of how some materials may initially ignite but then form a ‘char layer’
that prevents the formation of further gases and further combustion.
Oxygen: This is a basic component of combustion.
Ignition source: The ignition source is needed to heat up the fuel sufficiently to generate volatiles and then to ignite them. In the case of a gas the ignition source can act directly on the gas.
