Which type of fire extinguisher is appropriate for an electrical fire?

A Class C fire extinguisher is specifically designed for extinguishing fires that involve electrical equipment. These types of fires can occur in settings where electrical circuits or devices are present and are particularly dangerous as water and other conductive materials may exacerbate the situation, increasing the risk of electrocution or spreading the fire further.

Class C extinguishers typically use non-conductive agents, such as carbon dioxide or dry chemical agents, that can effectively smother the fire without conducting electricity. Using a Class C extinguisher on an electrical fire helps to safely eliminate the flames while minimizing the risk of accidental electric shock or further ignition of flammable materials.

The other types of extinguishers listed are not suitable for electrical fires. Class A extinguishers are meant for ordinary combustibles like wood or paper, Class B extinguishers are for flammable liquids, and Class D extinguishers are designated for combustible metals. Thus, using those in an electrical fire situation could lead to inadequate suppression of the fire, or in some cases, increase the danger.
