What is the best type of fire extinguisher for a commercial kitchen?

The best type of fire extinguisher for a commercial kitchen is a Class K extinguisher. Class K fire extinguishers best put out fires from cooking oil or fat by smothering and cooling flammable grease to eliminate the risk re-ignition.

Class K combustible cooking fires typically involve kitchen appliances containing quantities of cooking greases or oils that present special hazard extinguishing and re-flash concerns. The Class K listed fire extinguishers have effectively demonstrated the ability to address these commercial kitchen types of fire hazard situations.

These “wet” chemical fire extinguishers are now required by the National Fire Protection Association (NFPA) in commercial kitchens.
