When buying fire extinguishers for your home or business it’s extremely important to identify the potential fire risks first. Once the fire risks are determined you’ll be able to select the relevant fire extinguisher/s.
The Classes of Fire
Fires are classified according to the fuel that keeps them burning. There are currently six classes of fire:
Class A Fires
Class A fires are fuelled by combustible materials such as wood, paper, plastics, textiles and furniture. ABC Dry Powder, water, foam and wet chemical extinguishers are used to tackle Class A fires.
Class B Fires
Class B fires are fuelled by flammable liquids such as oil, paraffin or petrol. CO2, foam, and dry powder fire extinguishers are used to tackle Class B fires.
Class C Fires
Class C fires are fuelled by flammable gases such as hydrogen, butane, propane or methane. Dry powder fire extinguishers are used to tackle Class C fires.
Class D Fires
Class D fires are fuelled by combustible metals such as magnesium, aluminium or potassium. Specialist powder fire extinguishers are used to tackle Class D fires.
Electrical Fires
Electrical fires are fuelled by electrical appliances such as TV’s, computers and hair dryers. Once the electrical item is removed, the fire changes class. C02 and dry powder fire extinguishers are used to tackle electrical fires.
Class F Fires
Class F fires are fuelled by cooking fats or oils typically from chip-pans. Wet chemical fire extinguishers are used to tackle Class F fires.
Identification of Extinguishers
Fire extinguishers meeting BS EN 3 are required to be red in colour and colour coded with a small band of secondary colour which assists in the identification of the fire extinguisher.
The colour coding is as follows:
Water Fire Extinguishers – Red
Foam Fire Extinguishers – Cream
Dry Powder Fire Extinguishers – Blue
C02 Fire Extinguishers – Black
Wet Chemical Fire Extinguishers – Yellow
Fire Rating
All fire extinguishers that are capable of extinguishing Class A, Class B, or Class F fires carry a fire rating. This is indicated by a number and a letter. The number indicates the size of the fire it can extinguish under test conditions and the letter indicates the fire classification.
Class C, Class D and Electrical fire extinguishers do not carry a numerical rating.
Remember
The type of fire extinguisher you choose must conform to the appropriate British Standards (BSEN3), feature a BSI Kitemark and have a CE Mark. Without these certifications, the fire extinguisher will not be compliant with legislation and cannot be relied upon as safe fire protection solutions.
