Standard dry powder extinguishers are also called âABCâ extinguishers because they tackle class A, B and C fires, however they are not recommended for use in enclosed spaces. This is because the powder can be easily inhaled, and also the residue is very difficult to clean up after. ABC powder extinguishers can also be used on some electrical fires. Specialist dry powder extinguishers are used for flammable metals.
Dry powder extinguishers smother fires by forming a barrier between the fuel and the source of oxygen.
