There are generally 5 classes of fire. Thankfully only classes A, B and C are routinely encountered. The remaining classes of fire are difficult to calculate due to a number of additional considerations being required. It is recommended that expert advice is sought.
The classes of fire are based in the fuel and means of extinction. Whilst many fires involve electricity, it is not considered a specific class. However, only certain types of extinguishers are considered safe to use on electrical fires. It is essential that you, or the safety staff, recognise the correct type of extinguisher required before attempting to put out a fire. Using the wrong type of fire could be catastrophic, making the effects of the fire worse and/or injure the fire extinguisher operator.
Class A (Combustible Solids)
Fires involving combustible solids such as paper, wood, textiles, rubber, plastic and others.
Extinguished by cooling, usually with water.
Class B (Flammable Liquids)
Fires involving flammable liquids such as petrol, oil, paint, solvents and others
Extinguished by smothering (limiting oxygen supply) with foam, powder or CO2 extinguishers
Class C ( Flammable Gases)
Fires involving flammable gases such propane, butane, actylene and more
Extinguished by starving using a powder extinguisher
Class D (Flammable Metals)
Fires involving aluminium, magnesium, lithium and more
Extinguished by using a specialist powder extinguisher
Class F (Cooking Oils)
Fire involving cooking fats and oils used in deep fat fryers
Extinguished by turning the hot oil into a soap like substance by using a wet chemical extinguisher
