Fire Extinguisher Class C is used for fires involving which?

• A. Metals
• B. Ordinary combustibles
• C. Flammable liquids
• D. Energized electrical equipment

Answer: (D)

Fires involving energized electrical equipment require non-conductive extinguishing methods to avoid shocking anyone and to prevent electricity from carrying through the extinguisher. This category is used specifically for electrical fires, so the best choice is fires with energized electrical equipment. Metals, ordinary combustibles, and flammable liquids correspond to other fire types (Class D, Class A, and Class B, respectively) and use different extinguishing approaches.
