What type of extinguisher is specifically designed for Class K fires?

Stored-pressure wet chemical extinguishers are specifically designed for Class K fires, which involve cooking oils and greases like those found in kitchens. These extinguishers contain a solution that not only cools the flames but also creates a layer of foam to smother the fire, effectively preventing re-ignition. The wet chemical agent can penetrate the burning oil, which is crucial in extinguishing these types of fires safely and effectively.

This type of extinguisher is ideal for commercial kitchens or any setting where large amounts of oils or fats are used for cooking. The specialized nature of the foam in wet chemical extinguishers makes them more effective against this class of fire compared to other extinguisher types that may not adequately address the unique burning properties of oils and greases.
