Which class of extinguisher is indicated by a pictograph of a flame and a gasoline can?

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

Answer: (B)

Pictograms on extinguishers map directly to the type of fire they’re meant to fight. A flame paired with a gasoline can signals fires that involve flammable liquids, such as gasoline, oil, or solvents. That kind of fire is Class B. Extinguishers for Class B are designed to act on the liquid fuel—either by smothering it or by separating the fuel from the air—so they’re the right tool for these fires. The other options refer to different hazards: ordinary combustibles (like wood or paper), energized electrical equipment, or combustible metals, which have their own distinct pictographs and extinguisher types. So the best match for that pictograph is the Class B extinguisher.
