Fires are classified by the material that can burn and fire extinguisher types have corresponding pictograms to give you a visual cue as to whether they are suitable for the hazards in your workplace. So knowing the classes below should help you choose the correct fire extinguisher types for you.

Fires involving solid materials such as wood, paper, textiles, furniture and plastics.

Fires involving flammable liquids such as petrol, diesel or oils.




Fires involving gases.Class C fire pictogram
