What type of fire extinguisher is specifically meant for kitchen fires involving oils and fats?

The correct answer is Class K. Class K fire extinguishers are specifically designed to combat fires that involve cooking oils and fats, commonly found in kitchens. These extinguishers contain wet chemical agents that effectively cool and smother the flames generated by combustible cooking media, preventing the fire from reigniting.

Class K extinguishers are particularly vital in commercial kitchens where large amounts of cooking oil are used. They work by forming a barrier between the oxygen and the surface of the burning oil, while also creating a foam layer to absorb heat. This unique chemical reaction quenches the fire efficiently while minimizing the risk of splattering or spreading the flames.

Class A, B, and C extinguishers serve different purposes: Class A is for ordinary combustibles like wood and paper, Class B is designed for flammable liquids, and Class C is intended for electrical fires. While these extinguishers are essential in various fire situations, none of them are suitable for handling kitchen fires involving oils and fats, making Class K the specialized choice for that specific hazard.
