Fires near electrical equipment are classified as Class C fires. Which option correctly lists classes?

• A. Class A
• B. Class B
• C. Class C
• D. Class D

Answer: (C)

Fires involving electrical equipment are labeled Class C to indicate an electrical hazard. This class is dedicated to energized electrical fires and helps you pick a safe approach—different fuels require different extinguishing methods. The other classes map to different fire sources: Class A covers ordinary combustibles like wood and paper, Class B covers flammable liquids, and Class D covers combustible metals. Because water can conduct electricity, it’s not suitable for Class C fires. Use nonconductive extinguishing agents such as dry chemical powder or CO2, and, if possible and safe, shut off the power before fighting the fire.
