What is the appropriate extinguishing agent for Class K fires?

Class K fires involve combustible cooking oils and fats, typically found in commercial kitchens. The appropriate extinguishing agent for these types of fires is wet chemical. Wet chemical extinguishers are specifically designed for Class K fires because they effectively cool the burning material and create a blanket of foam that suppresses the fire. The unique formulation of wet chemical agents can also help to saponify the cooking oils, forming a soap-like substance that further helps to prevent re-ignition, making it essential for safely managing these types of fires.

Water is not appropriate for Class K fires as it can spread the fire and create hazardous situations. Foam agents are not suited for these types of fires either, as they are ineffective against burning cooking oils. Additionally, while dry chemical extinguishers can be used for various types of fires, including some kitchen fires, they do not have the specific properties needed to address the unique challenges posed by Class K fires effectively. Thus, the use of wet chemical extinguishing agents is paramount in ensuring safety when handling Class K fires.
