Extinguisher Classes;
Class A: Fuelled by common, freely burning materials such as paper, wood, coal, straw, tyres, textiles and other carbonaceous matter. Class A fires are the most common and can occur in almost any environment. Fight with Water, Foam, ABC Dry Powder or Wet Chemical extinguishers.
Class B: These fires are fuelled by flammable liquids, or materials that liquefy. They include petrol, diesel, paint, industrial oils and fats, ether, tar, paraffin and stearin, excluding alcohol and cooking oils. Fight with Foam, ABC Dry Powder, CO2 or Fire Blanket.
Class C: Fuelled by flammable gases such as propane, butane, natural (mains) gas, LPG (Liquid Petroleum Gas), medical and industrial gasses. Fight with ABC Dry Powder.
Class D: Class D fires are generally found in industry only as they are fuelled by metals. They include magnesium, aluminium, swarfs, sodium and powdered metals. Fight with Specialist Dry Powder, M28 for example. These Specialist Dry Powders extinguish metal fires by fusing the powder to form a crust, thus excluding oxygen.
Electrical fires are not classified in a group, as electricity is a source of ignition and, will fuel the fire until the supply is halted or disconnected. Warning note! Some electrical equipment can store lethal voltages in capacitors even if their power supply has been switched off, therefor fight with CO2 or ABC Dry Powder only, as these are charged with agents that do not conduct electricity.
Class F: These are very high temperature fires fuelled by cooking oils and fats, including butter. As such they are notoriously difficult to extinguish. Conventional extinguishers are not effective for class F fires as they do not cool sufficiently and, may cause flash back. Fight only with specialist Wet Chemical agent extinguishers.CO2 Extinguishers
