What class of fire extinguisher is specifically required for an electrical fire?

The specific class of fire extinguisher required for an electrical fire is Class C or BC. Class C fire extinguishers are designed to put out fires that involve energized electrical equipment, which can include wiring, appliances, and other electrical devices. This designation is crucial because using the inappropriate type of extinguisher could cause further hazards, such as electrocution or spreading the fire.

Class B extinguishers are suitable for flammable liquids and gases, while Class A extinguishers are intended for ordinary combustible materials like wood, paper, or cloth. Class D extinguishers are designed specifically for combustible metals and are not relevant to electrical fires.

Thus, choosing Class C or BC refers to the need for extinguishers that can safely extinguish fires involving electrical components without the risk of conducting electricity, making them the appropriate choice for this scenario.
