What type of extinguisher is recommended for Class C fires?

For Class C fires, which involve energized electrical equipment, extinguishers that use non-conductive agents are recommended because they do not pose a risk of electric shock during use. Non-conductive agents, such as carbon dioxide or dry chemical, are effective at extinguishing the fire without creating a conductive path that could lead to an electrical hazard.

Using water-based extinguishers is not suitable for Class C fires as water is a conductor of electricity and can increase the danger of shock. Foam-based extinguishers are designed for flammable liquids and are also not appropriate for electrical fires. While chemical powder extinguishers can be effective on Class C fires, the emphasis on non-conductive agents specifically underscores the need to prioritize safety when dealing with electrical equipment. Therefore, using extinguishers that are explicitly designed to be non-conductive ensures that the person responding to the fire can do so without risk to their safety.
