An example of a class C fire is?

• A. House fire
• B. Fuel fires
• C. Electrical Fires
• D. Metal fires

Answer: (C)

Class C fires involve energized electrical equipment. This is why the example fits best: it specifically identifies the fire type that arises from electrical devices that are or were powered. A house fire is typically Class A, rooted in ordinary combustibles like wood and paper; fuel fires are Class B, involving flammable liquids; metal fires are Class D. When addressing an electrical fire, the priority is to de-energize the equipment if it can be done safely, and to use a nonconductive extinguisher such as carbon dioxide or a dry chemical powder. Water should be avoided on energized electrical fires because it can conduct electricity and pose a shock hazard.
