Which class of fire includes cooking oils and fats?

Cooking oils and fats are classified as a Class K fire. This classification specifically addresses fires that involve combustible cooking media, which typically includes oils and fats commonly used in kitchens. Class K fires require specialized extinguishing agents that can effectively cool the burning oils and prevent re-ignition, such as wet chemical agents.

In contrast, Class A fires involve ordinary combustible materials like wood, paper, and cloth; Class B fires pertain to flammable liquids and gases; and Class C fires are associated with electrical equipment. None of these other classes directly address the unique characteristics and hazards presented by cooking oils and fats, making Class K the appropriate classification for these types of fires.
