In the event of an electrical fire in a hotel, which type of fire extinguisher should be used?

• A. Type A
• B. Type B
• C. Type C
• D. Type D

Answer: (B)

Electrical fires require an extinguisher that is safe for live electrical equipment. These are extinguishers rated for electrical fires (Class C) and they use non-conductive agents such as dry chemical powder or carbon dioxide. The goal is to suppress the flame without creating a path for electricity to travel through the extinguisher or the agent, which water-based extinguishers could do. Therefore, avoid water or water-based extinguishers and choose a CO2 or dry chemical extinguisher labeled for electrical fires (or a multipurpose extinguisher rated for Class C). If safe to do so, also cut power to the equipment, and evacuate if the fire grows or you cannot control it.
