Which type of fire extinguisher is best for electrical fires?

The best type of fire extinguisher for electrical fires is a Class C extinguisher. This type is specifically designed to handle fires involving energized electrical equipment, such as motors, appliances, and wiring. Class C extinguishers use non-conductive agents, meaning they can extinguish the fire without conducting electricity and creating a risk of electrical shock.

In contrast, Class A extinguishers are meant for ordinary combustible materials like wood and paper, and using one on an electrical fire could pose serious dangers due to the possibility of electrical conduction. Class B extinguishers are for flammable liquids and gases, which could also be hazardous in an electrical context. Class D extinguishers are specifically used for combustible metals, which are unrelated to electrical fires. Therefore, a Class C extinguisher is the appropriate choice for safely tackling electrical fires.
