When To Use A Foam Fire Extinguisher?
It is recommended to use a foam fire extinguisher for class A and class B fires.
Fires that are categorised as class A involve flammable solids such as rubber, wood, paper and textile materials, where as class B fires involve flammable liquids such as kerosene or petrol.
Foam fire extinguishers are extremely popular in environments such as warehouses, textile factories, storage facilities, petrol stations and workshops as they are more likely to contain combustible materials or flammable liquids.
It is NOT advised to use a foam fire extinguisher for class F fires or in other words fires involving fats and oils as they have proven to be ineffective, for safety reasons it is suggested that a foam extinguisher is paired with a wet chemical fire extinguisher.
