What type of fire extinguisher is specifically used for Class K fires?

Class K fires involve cooking oils and fats, commonly found in commercial kitchens. The unique challenge with these types of fires is that traditional extinguishing agents can exacerbate the situation by splattering the burning oil, potentially spreading the fire.

The wet chemical stored pressure extinguisher is specifically designed for Class K fires. It contains agents like potassium acetate, which effectively extinguish the flames by cooling the oil and creating a barrier between the oxygen and the fuel. This type of extinguisher not only suppresses the fire but also helps to prevent reignition, making it an ideal choice for kitchen environments where such fires are likely to occur.

Other types of extinguishers, such as CO2, water, and dry chemical, are not suitable for Class K fires. CO2 extinguishers work well for electrical and flammable liquid fires but do not cool the burning oils effectively. Water extinguishers can create a hazard by causing the oil to splatter, and dry chemical extinguishers, while versatile, may not be optimized for the challenges posed by cooking oils. Therefore, the wet chemical stored pressure extinguisher is essential for safely addressing Class K fires.
