Class C fires involve which type of materials?

Class C fires are specifically associated with electrical equipment. When dealing with electrical fires, it is crucial to use the appropriate type of extinguishing agent, as using water or non-designated extinguishers can be extremely hazardous and may lead to electric shock or further fire spread.

The other types of fires listed involve different materials: flammable solids are categorized under Class A fires, which include ordinary combustibles like wood and paper; flammable liquids fall under Class B fires; and combustible metals are classified as Class D fires, which require special handling and extinguishing agents due to the unique properties of the metals involved. Hence, it's important to correctly identify Class C fires to ensure safety and effective firefighting strategies.
