What type of fire extinguisher is best for electrical fires?

The best type of fire extinguisher for electrical fires is a CO2 extinguisher. This type of extinguisher works effectively by displacing the oxygen around the fire, which helps to suffocate it without leaving any residue that could damage electrical equipment. CO2 extinguishers are non-conductive, making them particularly safe for use on electrical fires because they minimize the risk of conducting electricity and causing further hazards.

Water-based extinguishers, on the other hand, can conduct electricity and are therefore not safe for use on electrical fires. Foam extinguishers may also be effective on flammable liquid fires but are not recommended for electrical fires due to potential conductivity. Dry chemical extinguishers can be effective for various types of fires, including electrical, but CO2 extinguishers provide a significant advantage in preventing equipment damage and ensuring safety when dealing with electrical hazards.
