Which type of fire extinguishers are best suited for commercial kitchens?

Class K fire extinguishers are specifically designed for use in commercial kitchens, particularly those that involve cooking with oils and fats, which are common in food preparation. These fire extinguishers contain a special wet chemical agent that effectively reacts with cooking oil fires to create a soapy foam that cools the flames and prevents re-ignition.

This reaction is particularly important because cooking oil fires can be exceptionally dangerous and hard to extinguish with water or traditional fire extinguishers. Other classes of extinguishers, such as Class A, B, and C, are geared towards different types of fires: Class A is for ordinary combustibles (like wood and paper), Class B is for flammable liquids, and Class C is for electrical fires. While these may have some application in a kitchen setting, they do not provide the specialized protection needed for grease fires, which is why Class K is the preferred choice in commercial cooking environments.
