Class C fires involve which?

Class C fires involve which?

• A. Bedding and paper
• B. Flammable liquids
• C. Electrical fires such as appliances, outlets, and wiring
• D. Combustible metals

Answer: (C)

Class C fires involve energized electrical equipment. When the fire is within appliances, outlets, or wiring, the current itself drives the hazard, so you need extinguishing methods that do not conduct electricity. Use non-conductive extinguishing agents such as carbon dioxide or dry chemical extinguishers rated for electrical fires, and if it’s safe, cut power to the device first. Water must be avoided on live electrical fires because it can conduct electricity and cause shock or spread the fire. If the electricity is shut off and the fuel source is addressed, the situation may then be treated under the appropriate category for the actual material involved. For context, bedding and paper are ordinary combustibles, flammable liquids are a different class, and combustible metals form another class. Understanding these distinctions helps you choose a safe and effective approach.
