What class of fire extinguisher is appropriate for electrical fires?

The appropriate class of fire extinguisher for electrical fires is Class C. Class C fire extinguishers are specifically designed to combat fires that involve energized electrical equipment, such as wiring, appliances, and circuit breakers. These extinguishers typically use non-conductive agents that safely quell the flames while minimizing the risk of electrical shock to the person using the extinguisher.

Choosing the correct extinguisher is vital for safety. Class A extinguishers, for instance, are effective for ordinary combustible materials like wood and paper, and using them on an electrical fire could lead to dangerous outcomes since they may not be non-conductive. Similarly, Class B extinguishers are meant for flammable liquids, and Class D extinguishers are for combustible metals, none of which are suitable for extinguishing electrical fires. Thus, for any situation involving live electrical components, utilizing a Class C extinguisher is essential to ensure effective firefighting while maintaining user safety.
