BS EN 2 is the very brief British Standard by BSI that specifies the “Classification of fires”.
These classifications are as follows:
- Class A - fires involving solid materials, usually of an organic nature, in which combustion normally takes places with the formation of glowing embers.
- Class B - fires involving liquids or liquefiable solids.
- Class C - fires involving gases.
- Class D - fires involving metals.
- Class F - fires involving cooking media (vegetable or animal oils and fats) in cooking appliances.
Note that there is no definition of a Class E in this standard, although the phrase
"class E" is often misused to describe fires, hazards and cover concerning electrical
hazards.
It is important to note that, as electricity does not burn, fires
involving electrical hazards are in fact always fires of another class with the additional complication of the presence of an electrical
hazard.
BS EN 2 is the English language version of the European Standard EN 2, published by European Committee for Standardisation (“CEN”).
