A Class C fire extinguisher is used for which type of fires?

• A. Organic solvents
• B. Wooden materials
• C. Electrical equipment
• D. Cooking oils

Answer: (C)

Fires in electrical equipment are handled with extinguishers labeled for energized electrical fires. A Class C extinguisher uses non-conductive agents (like dry chemical powder or CO2) that suppress the fire without creating a path for electricity to flow. That’s why it’s the right choice for fires involving electrical equipment, especially while the power is still on or uncertain. Water-based methods are dangerous here because water conducts electricity, which is why other materials like organic solvents (flammable liquids) or wooden materials (ordinary combustibles) aren’t addressed by Class C. Cooking oils are typically addressed by Class K (or F in some codes), not electrical fires.
