Commercial Kitchen Fire Extinguisher That Meets Code and Protects Your Business
Cooking fires are one of the leading causes of damage in commercial properties. Class K fire extinguishers are specifically designed to stop dangerous grease fires quickly and safely, and they are required in most commercial kitchens.
If your facility cooks with oils or fats, a Class K fire extinguisher is not optional. It is a critical life safety system that must be properly installed, inspected, and maintained to meet fire code requirements.
State Systems provides Class K fire extinguisher inspection, service, and replacement to keep your kitchen compliant and protected.
What Is a Class K Fire Extinguisher?
A Class K fire extinguisher is a specialized extinguisher designed to combat fires involving cooking oils, animal fats, and grease commonly found in commercial kitchens.
Unlike standard extinguishers, Class K units discharge a wet chemical agent that rapidly cools the fire, reacts with hot grease through saponification, and creates a foam barrier that helps prevent re ignition.
This makes Class K extinguishers significantly more effective and safer for kitchen environments than standard ABC or CO2 extinguishers.
What Are Class K Fire Extinguishers Used For?
Class K fire extinguishers are used to control commercial cooking fires involving high temperature oils and grease, including:
-
Deep fryers
-
Griddles and flat top grills
-
Ranges and stovetops
-
Woks
-
Commercial ovens
-
Grease producing cooking equipment
They are required in environments such as restaurants, cafeterias, food trucks, commercial kitchens, and institutional kitchens like schools, hospitals, and assisted living facilities.
If grease or cooking oil is part of your operation, a Class K fire extinguisher is essential.
Can a Class K Fire Extinguisher Be Used on Any Fire?
No. A Class K fire extinguisher is not designed for all fire types.
It is specifically engineered for Class K fires involving cooking oils and fats. While it may extinguish some Class A fires involving ordinary combustibles, it should never be used as a replacement for other required extinguisher types.
Class K fire extinguishers should not be used on:
-
Electrical fires
-
Flammable liquid fires such as gasoline or solvents
-
Combustible metal fires
Most commercial buildings require multiple extinguisher types placed according to hazard and risk.
What Is a Class K Fire Extinguisher Used For in Commercial Kitchens?
In commercial kitchens, grease fires burn hotter and can reignite quickly if not handled properly. Using water on a grease fire can cause flames to spread rapidly and create serious injury risks.
Class K fire extinguishers are designed to:
-
Suppress flames immediately
-
Cool hot oils and grease
-
Prevent re ignition
-
Reduce injury and property damage
They are required by NFPA 10 and most local fire codes and are commonly reviewed during fire inspections and health department visits.

Class K Fire Extinguisher vs Other Fire Extinguishers
Class A extinguishers are designed for paper, wood, and trash and are not suitable for grease fires.
Class B extinguishers are used for flammable liquids but are not designed for cooking oils.
Class C extinguishers are intended for electrical fires only.
Class D extinguishers are required for combustible metal hazards.
Class K fire extinguishers are the only extinguisher type specifically engineered for commercial cooking fires involving grease and oils.
Where Should a Class K Fire Extinguisher Be Located?
According to NFPA 10: Standard for Portable Fire Extinguishers, Class K fire extinguishers must be installed in commercial kitchens that use cooking oils or fats.
Fire codes require Class K fire extinguishers to be:
• Located within 30 feet of cooking equipment
• Easily accessible to staff
• Clearly visible and properly labeled
• Mounted so they remain free from obstructions
They should also be positioned so employees can access them without reaching directly over the cooking hazard.
Improper placement can lead to failed inspections, code violations, and increased risk during a kitchen fire emergency.
