Which fire extinguisher should be used on electrical fires?

The correct fire extinguisher for use on electrical fires is specifically designed to combat fires that involve energized electrical equipment, which is why a Class C fire extinguisher is the appropriate choice. Class C extinguishers typically use non-conductive agents, such as carbon dioxide or dry chemical substances, that can effectively extinguish the flames without posing a risk of electrocution to the person using the extinguisher or inadvertently causing further electrical hazards.

Class A extinguishers are intended for ordinary combustibles, such as wood and paper, while Class B extinguishers are suitable for flammable liquids and gases. Class D extinguishers are specifically designed for combustible metals and are not applicable for electrical fires. Thus, the unique design of Class C extinguishers makes them essential for safely addressing fires involving electrical equipment.
