The pictograph of flames in a frying pan represents a _____ extinguisher.

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

Answer: (B)

A pictograph showing flames over a frying pan points to fires involving cooking oils and fats. Those fires require a special extinguisher that can handle the unique properties of hot oil, which is exactly what Class K extinguishers do. They use a wet chemical agent that saponifies fats and oils to form a soapy layer, cooling and smothering the fire to prevent reignition. This makes Class K the appropriate choice for kitchens where oils and fats are present.

Other extinguisher classes don’t fit: fires involving ordinary combustibles like wood or paper point to Class A, flammable liquids like gasoline point to Class B, and metal fires point to Class D. The frying-pan symbol is specific to cooking-oil fires, which is what Class K is designed to address.
