Which fire extinguisher class is used for kitchen fires?

• A. Class A - solid materials
• B. Class B - flammable liquids
• C. Class C - electrical fires
• D. Class K - Kitchen fires

Answer: (D)

Fires in kitchens are typically grease fires, involving cooking oils and fats, which need a specialized approach. Fire extinguishers are categorized by the fuels they’re designed to fight, and the one for cooking oils and fats is the Class K extinguisher. It uses a wet chemical agent that saponifies fats, turning the oil into a soapy layer that cools and blankets the fuel, preventing reignition. This makes it safer and more effective for grease fires than water or other extinguisher types, which can spread burning oil or fail to cool it properly. The other extinguisher classes target ordinary combustibles, flammable liquids, or electrical fires, which don’t address the unique hazards of kitchen oils.
