Which type of extinguisher is suitable for Class C fires?

The correct type of extinguisher for Class C fires is one that uses non-conductive agents, which is characteristic of Class C extinguishers specifically designed for electrical fires. Class C fires involve live electrical equipment and present a unique danger because using a standard water-based extinguisher can result in shock or further ignition.

Class C extinguishers typically use materials such as carbon dioxide (CO2) or dry chemical agents that do not conduct electricity, making them safe and effective for use on electrical fires. The proper use of a Class C extinguisher helps ensure the safety of the operator and those nearby, allowing for effective suppression of the fire without the risk of electrocution.

In contexts where multi-class capability is needed, such as with an ABC extinguisher that can handle Class A, B, and C fires, the presence of non-conductive materials in both Class C and ABC extinguishers makes them suitable for electrical fires as well, but the key characteristic of Class C extinguishers is their specific design for that purpose, which is why they are the most direct answer to the question.
