Which class is associated with electrical equipment fires?

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

Answer: (C)

Electrical fires are classified as Class C because electricity is involved. This labeling signals responders to de-energize the equipment if safe and to use extinguishing agents that do not conduct electricity, avoiding water on energized equipment to prevent shock or current flow. If power can be shut off safely, you can switch to a more appropriate extinguishing approach, but the presence of electricity places it in this category. Other classifications cover ordinary combustibles, flammable liquids, or combustible metals, which do not describe electrical hazards. So the association with electrical equipment fires is Class C.
