What are the recommended steps to safely extinguish an electrical fire?

• A. Use water to extinguish.
• B. Cut power and use a non-conductive extinguisher such as CO2 or dry chemical; never use water on electrical fires.
• C. Use a foam extinguisher.
• D. Use a wet cloth.

Answer: (B)

Electrical fires require removing the power source and using a non-conductive extinguisher. Water should never be used on energized equipment because it conducts electricity, creating a shock hazard for you and potentially spreading the fire through conductive paths. If it’s safe to do so, switch off the power at the main disconnect or circuit breaker to stop the electrical supply. Then use an extinguisher that is suitable for electrical fires, such as carbon dioxide or a dry chemical type, which do not conduct electricity and can smother the flame or interrupt the chemical reaction without creating a conductive path. Foam extinguishers aren’t ideal for live electrical gear because they’re typically water-based and can still pose shock risk, and a wet cloth offers no effective fire control. If the fire is too large or the power cannot be cut safely, evacuate and call emergency services.
