Class K fire extinguishers are mainly used in which environment?

Class K fire extinguishers are specifically designed to combat fires that involve cooking oils and fats, which are commonly found in food preparation areas such as restaurants and kitchens. This class of extinguisher is formulated with a wet chemical agent that effectively cools and suppresses flames, particularly those created by cooking oils that can result in rapid and dangerous flare-ups.

While Class K extinguishers might be present in other environments, they are primarily targeted towards commercial kitchens and food service operations where the risk of grease fires is highest. This makes food preparation areas the most relevant and appropriate environment for the use of Class K extinguishers, as they are equipped to handle the unique challenges posed by these types of fires.
