Class C fires involve which type of hazard?

• A. Fires that involve paper.
• B. Fires that involve electricity.
• C. Fires that involve grease.
• D. Fires that involve wood.

Answer: (B)

Class C fires involve energized electrical equipment. The hazard is live electricity, which can shock you and push the fire to spread through conductive paths. Because water and other conductive agents are dangerous on energized equipment, use non-conductive extinguishing methods such as dry chemical powder or carbon dioxide, and only fight the fire if you can do so safely after power is turned off. If the power is shut off, the fire’s classification may change depending on the fuel involved.
