What is the proper use of a fire extinguisher on an electrical fire?

• A. Use water
• B. Use an appropriate non-conductive extinguisher (e.g., CO2, dry chemical) and stand at a safe distance; do not use water
• C. Use any extinguisher available
• D. Use your hands to smother the flames

Answer: (C)

When extinguishing an electrical fire, the priority is to avoid creating a conductive path for electricity while stopping the fire. Water should not be used because it conducts electricity, which can cause electric shock or energize surrounding metal parts, making the situation much more dangerous. The best approach is to use a non-conductive extinguisher such as carbon dioxide or a dry chemical type and keep a safe distance while you sweep the base of the flames. If possible, cut power to the equipment before approaching, and only attempt to extinguish if it’s safe to do so and the fire is small enough to control with the right extinguisher.

Options that mention using water or attempting to smother the flames with bare hands are unsafe and ineffective on electrical fires because of the risk of shock and the inability to control the electrical current, whereas a non-conductive extinguisher provides a safer, appropriate means to suppress the fire.
