Explanation
For electrical fires involving computer equipment, the correct extinguisher types are Class C and Class ABC. Class C extinguishers are specifically rated for energized electrical equipment fires - they use non-conductive agents (such as CO2 or dry chemical) that won't conduct electricity back to the user. Class ABC extinguishers are multi-purpose and cover Class A (ordinary combustibles like plastic and paper), Class B (flammable liquids), and Class C (electrical) fires, making them ideal for a home environment where multiple fire types are possible. Class K (A) is designed for commercial kitchen cooking fires (grease). Class B (D) covers flammable liquids but is not rated for electrical fires. Baking soda (B), while it can smother small fires, is not a certified extinguisher and is unreliable.
