Principle causes of fires in buildings 

The three basic essentials required before any fire can start are:

  1. Fuel, i.e. something to burn
  2. Air, i.e. oxygen to sustain combustion
  3. Heat.

The process of combustion or burning can be likened to a triangle as shown in Figure 1.
Fire Triangle

Removal of any one of the sides of that triangle will result in extinguishment of the fire and this is the principle on which all forms of fire extinguishment are based.
