Which type of fire extinguisher is suitable for electrically energized equipment?

A Class C fire extinguisher is specifically designed for fires involving energized electrical equipment. The agents used in Class C extinguishers are non-conductive, which is critical when dealing with electrical fires since using a conductive agent could result in serious injury or further fire risk. Class C extinguishers typically contain agents like carbon dioxide (CO2) or dry chemical powder that effectively extinguish fires without conducting electricity, making them safe for such applications.

In contrast, other types of extinguishers are not appropriate for electrical fires. For instance, Class A extinguishers are suited for ordinary combustibles like wood and paper, while Class B extinguishers are meant for flammable liquids such as gasoline and oil. Class D extinguishers, on the other hand, are designed for combustible metals and are not relevant to electrical fires. Understanding the classifications and appropriate uses of fire extinguishers is crucial for safety and effective response during fire emergencies.
