The pictograph of a flame and an electrical plug and socket represents which class extinguisher?

• A. Class A
• B. Class B
• C. Class C
• D. Class D

Answer: (C)

Focus on what the pictograph signals: a flame paired with an electrical plug and socket. That combination indicates a fire involving electrical equipment. Extinguishers for energized electrical fires are designed to be non-conductive and safe to use on live circuits, typically using dry chemical or CO2. Hence the symbol points to Class C extinguishers, used for electrical fires. It’s not pointing to ordinary combustibles, flammable liquids, or metal fires, which would be shown with different icons.
