Which class of fire pertains to cooking oils and fats?

Cooking oils and fats fall under Class K fires. This classification specifically addresses fires that involve cooking mediums such as vegetable oils and animal fats, which are commonly used in food preparation. Class K fires are notable because these types of oils can ignite and burn at very high temperatures, creating unique challenges in firefighting.

The extinguishing agents typically used for Class K fires are specifically formulated wet chemical agents that not only cool the flames but also create a barrier between the fuel and the air, effectively smothering the fire. This makes them distinct from the agents used for other classes of fires.

In contrast, Class A fires pertain to ordinary combustibles like wood and paper, Class B fires involve flammable liquids and gases, and Class D fires involve combustible metals, which are handled with entirely different techniques and extinguishing agents. Understanding this classification is critical for effective firefighting and safety in environments where cooking occurs.
