Fire Extinguisher Class for electrical fires?

• A. Class A - suitable for fires involving solid materials
• B. Class B - fires involving flammable liquids and gases
• C. Class C - halon for electrical fires
• D. Class D - Heavy metal fires

Answer: (C)

For electrical fires, the safest extinguishing option is one designed for use on live electrical equipment, using a non-conductive extinguishing medium. That classification is Class C, which means the extinguisher is appropriate for electrical fires and won’t conduct electricity or create a shock hazard. It’s important because water or other conductive agents can spread the current and worsen the hazard on energized equipment. The other classes target different fuels: solid materials, flammable liquids, and metal fires, which isn’t what you have with electrical gear. While older answers may mention halons, modern practice uses non-conductive media like dry chemical or CO2 for electrical fires.
