fire classification

Fires are classified according to the burning materials. Classification aids the correct choice of fire extinguisher. The European norm EN2 classifies 5 groups:
Class A: Solid materials (e.g. paper, textiles, wood)
Class B: Fluid materials or those which become fluid (e.g. petrol, synthetic materials)
Class C: Gas (e.g. propane, butane)
Class D: Metal
Class F: Fats and oils
Classification E for electrical fires was abolished on introduction of the new European EN2 norms.
