However, researchers say that the diagram should be adapted to help people get to grips with how fires really start because the Fire Triangle misses out a vital part of the fire starting process.
Experts recommend that adding the fourth essential element of a ‘chemical chain reaction’ will create a more accurate representation of the combustion process (this is the chemical process where fuel reacts rapidly with a source of oxygen to create fire i.e. burning).
Hence the birth of the Fire Tetrahedron:
