What types of substances are classified under Class C fires?

Class C fires are specifically associated with electrical equipment and appliances. This classification includes fires that involve live electrical wires, motors, and other powered devices. The proper way to extinguish these types of fires involves using appropriate fire extinguishers, such as those with a CO2 or dry chemical agent, which do not conduct electricity.

The correct answer pertains to substances that fall under the Class C classification due to their unique characteristics and hazards when they are energized. Using water or standard extinguishing agents may present a risk due to electricity, which is not a factor with the substances listed in the other classifications. Each of those represents different categories of flammable materials: Class A involves ordinary combustibles like wood and paper, Class B is for flammable liquids like LPG and propane, and Class D refers to combustible metals. Understanding these classifications is vital for ensuring safety and proper response in case of a fire involving different types of materials.
