Which class of fire extinguisher should be used on an electrical fire?

The appropriate class of fire extinguisher for an electrical fire is Class C. This classification is specifically designed for fires that involve electrical equipment, such as wires, circuits, and appliances. Class C extinguishers utilize non-conductive agents, typically carbon dioxide (CO2) or dry chemicals, that effectively extinguish the flames without conducting electricity or causing additional hazards.

Using a Class C extinguisher is essential because employing water or other conductive agents could pose a serious risk of electric shock or further electrical hazards. Therefore, Class C extinguishers are equipped to handle the unique challenges associated with electrical fires, making them the safest and most effective option in these situations.
