K-Class Extinguishers
K-Class Fire Extinguishers for Commercial Kitchens
Specialized fire extinguisher sales, inspection, and service for restaurants, commercial kitchens, and food service operations throughout Magnolia, Greater Houston, and surrounding communities.
Commercial kitchens present unique fire hazards that standard ABC dry chemical extinguishers are not designed to handle. High-temperature cooking oils and fats can ignite at extreme temperatures and re-ignite after an apparent knockdown — a phenomenon that makes kitchen fires particularly dangerous. Titan Fire & Safety provides K-Class fire extinguisher sales, inspection, and service for restaurants and commercial kitchens throughout Magnolia, Greater Houston, Tomball, The Woodlands, Spring, Cypress, Conroe, Montgomery, Waller, Hockley, Pinehurst, Plantersville, and surrounding communities — ensuring your kitchen is protected with the right equipment.
Why K-Class Extinguishers Are Required for Commercial Kitchens
K-Class extinguishers use a wet chemical agent specifically formulated to combat fires involving cooking oils and fats. The agent works by saponification — a chemical reaction that converts the burning oil into a soapy foam that cools the fuel and prevents re-ignition. Standard ABC dry chemical extinguishers do not provide this protection and can actually scatter burning oil, making a kitchen fire worse. NFPA 10 and most local fire codes require K-Class extinguishers in commercial cooking operations where deep fryers, griddles, or other high-temperature cooking equipment is used.

When Are K-Class Extinguishers Required?
NFPA 10 requires K-Class extinguishers in commercial cooking areas where the hazard involves cooking oils and fats. They must be located within 30 feet of the cooking equipment and must be inspected annually by a licensed technician. K-Class extinguishers must also be inspected after any use and recharged immediately before being returned to service. Many local fire codes and insurance policies have additional requirements for commercial kitchen fire protection — Titan Fire & Safety can help you understand and meet all applicable requirements.

Frequently Asked Questions
Do I need a K-Class extinguisher if I already have a kitchen suppression system?
Yes. NFPA 10 and most fire codes require a K-Class portable extinguisher in commercial cooking areas in addition to any fixed suppression system. The portable extinguisher provides a first line of defense and backup protection if the suppression system does not fully extinguish the fire.
Can I use an ABC extinguisher in my commercial kitchen?
ABC dry chemical extinguishers are not appropriate for cooking oil fires and are not a substitute for K-Class extinguishers in commercial kitchens. Using an ABC extinguisher on a cooking oil fire can scatter the burning oil and make the fire worse. K-Class extinguishers are specifically designed for this hazard.
How often does a K-Class extinguisher need to be inspected?
K-Class extinguishers require annual professional inspection under NFPA 10, plus a visual inspection every 30 days. They must also be inspected and recharged after any use. Six-year maintenance is required at the appropriate interval.
What size K-Class extinguisher do I need?
The correct size depends on the type and volume of cooking equipment in your kitchen. We will assess your operation and recommend the appropriate size and rating to meet NFPA 10 requirements.
