What is the correct fire extinguisher for a fire involving electrical equipment?

A Class C fire extinguisher is specifically designed for fires involving electrical equipment. These fires are particularly dangerous because using the wrong type of extinguisher can lead to serious risks, including electric shock. Class C fire extinguishers typically use non-conductive agents, such as carbon dioxide (CO2) or dry chemical agents, to suffocate the fire without conducting electricity.

It's crucial to use appropriate firefighting methods to deal with electrical fires, as any water-based extinguisher could conduct electricity and create a hazardous situation for the user. Other classes, such as Class A and Class B, target fires involving ordinary combustibles and flammable liquids, respectively, but do not cover the unique requirements of electrical fires. Therefore, for safety and effectiveness, a Class C fire extinguisher is the correct choice when dealing with electrical equipment fires.
