Where are Class K fires typically found?

Class K fires are specifically related to cooking oils and fats that are commonly used in commercial kitchens. These fires can arise from deep fryers, cooking ranges, and other appliances where high-temperature cooking oils are employed. The unique nature of these fires necessitates specialized extinguishing agents, such as those found in Class K fire extinguishers, which work effectively on the specific chemical reactions occurring with cooking oils.

In contrast, residential homes may experience different types of fires, such as those involving common combustible materials or electrical components. Laboratories generally deal with chemical fires that may not fit the parameters of Class K, while storage facilities with flammable materials could involve a range of fire classes depending on the specific substances stored. Therefore, the focus on commercial kitchens is what makes this choice accurate.
