Foam fire extinguishers can be used on both Class A fires, which involve solid combustibles such as wood or textiles, and Class B fires, which involve flammable liquids such as petrol or diesel. They can be recognised by their cream label stating 'Foam'.
The most common size is 6 litres although they are available in a range of sizes from 1 litre up to 9 litres. If the foam fire extinguisher has passed the 35kV conductivity test, it is safe for accidental use on electrical equipment, which increases the operator's safety.
Foam fire extinguishers work in two ways. Firstly, they are mostly water-based so have the same cooling effect on the fuel as water fire extinguishers, and put out the fire by lowering the temperature. Secondly, and what differentiates them from water extinguishers, is the addition of 'Aqueous Film Forming Foam', or 'AFFF'. This foam smothers the fire, and seals in the flammable vapours. This creates a barrier between the flammable liquid's surface and the flames which is foam extinguishers can be used effectively on class B fires.
Foam fire extinguishers are very useful in spaces with more than one type of hazards such as offices, warehouses and commercial spaces. Due to their ability to combat flammable liquid fires, they are also advantageous to have in vehicles and boats. Especially when paired with CO2 extinguishers for electrical fires, they offer well-rounded fire safety for most premises.
Foam extinguishers are designed to prevent re-ignition, they are lighter than the closest equivalent water extinguishers, and are non-toxic and non-damaging to the majority of materials.
