A combustible gas is one which ignites to burn, deflagrate or detonate when mixed with air and an ignition source.
Combustion is a fairly simple chemical reaction in which Oxygen is combined rapidly with another substance resulting in the release of energy. This energy appears mainly as heat – sometimes in the form of flames.
The process of combustion can be represented by the well known
fire triangle.

Three factors are always needed to cause combustion:

1.  A source of ignition
2.  Oxygen
3.  Fuel in the form of a gas or vapour
