A burning 6-amp motor should be extinguished with what type of fire extinguisher?

Explanation:
When a fire involves electrical equipment, you choose an extinguisher rated for electrical fires. A burning motor is electrical equipment and is often energized, so you want a nonconductive agent that won’t carry current. A Class C extinguisher is designed for energized electrical fires, using agents like dry chemical or CO2 that extinguish the flame without creating a conductive path. Water-based extinguishers are unsafe here because water conducts electricity and can pose a shock hazard. The other classes correspond to different fuels—ordinary combustibles, flammable liquids, or metals—and aren’t appropriate for an electrical motor fire. If it’s safe to do so, shut off power before spraying and use the Class C extinguisher.
