What is the purpose of using a Class K fire extinguisher?

The purpose of using a Class K fire extinguisher is specifically designed to extinguish fires that involve cooking oils and fats, which are commonly found in commercial kitchens and restaurants. This class of extinguisher uses a special wet chemical agent that can cool the flames and also create a layer of foam on top of the cooking oil, effectively preventing re-ignition.

Using a Class K extinguisher on cooking oils and fats is important because traditional extinguishing agents, such as water, can cause the burning oil to splatter and spread the fire, potentially endangering the lives in the area and increasing damage. The unique properties of the Class K extinguisher make it essential for safely addressing these specific types of fires.
