Fire extinguisher used for electrical equipment because the extinguishing agent is non-conductive.

• A. Type A fire extinguisher
• B. Type D fire extinguisher
• C. Type B fire extinguisher
• D. Type C fire extinguisher

Answer: (D)

Fires involving electrical equipment require a non-conductive extinguishing agent to prevent electrical shock and current from traveling through the extinguisher. An extinguisher designed for electrical fires uses a non-conductive agent, making it safe to apply to energized equipment without creating a conductive path for electricity. This is why it’s the appropriate choice for electrical equipment. Other fire types target different fuels—ordinary combustibles, flammable liquids, or metals—and are not suitable for electrical fires, and using a conductive or inappropriate agent on electrical gear can worsen the situation or pose serious hazards.
