Class Charlie fire involves what type of equipment?

• A. Combustible metals
• B. Flammable liquids
• C. Wood and paper
• D. Energized electrical equipment, conductors, or appliances

Answer: (D)

Class C fires involve energized electrical equipment. The fire’s source is electricity—things like live motors, wiring, switches, or appliances. Because electricity is involved, using water is dangerous since it conducts electricity, so the recommended approach is to use non-conductive extinguishing agents (such as dry chemical powders or CO2) and, if safely possible, shut off the power before or while fighting the fire. The other options describe fires caused by ordinary combustibles (wood, paper) or flammable liquids, which are different classifications and not energized electrical fires.
