Kitchen Fire Suppression
Class K Fire Extinguishers for Commercial Kitchens
Class K fire extinguishers discharge specialized potassium acetate wet chemical agents designed to smother high-temperature cooking oil and grease fires. Every commercial kitchen in Southern California must maintain tagged Class K units under NFPA 10 and California Title 19 regulations.
Compliance & Technical Summary for Commercial Kitchen Owners
Class K extinguishers serve as the required manual backup to automatic hood suppression systems. When deep fryers, griddles, or wok lines ignite, wet chemical agents create a thick foam blanket through saponification, sealing off oxygen and cooling cooking oil below its auto-ignition point.
Regulatory Requirements: NFPA 10 & California Title 19
Class K Inspection & Service Checklist
Common Fire Code Violations Avoided
Local fire marshals and health inspectors frequently issue citations for missing Class K units, expired annual tags, blocked access corridors, or substituting standard ABC dry chemical extinguishers on cooking lines. Using dry chemical on hot cooking grease can cause violent re-ignition or splatter burns.

What Customers Say About This Service
I own a restaurant in Buena Park, and on Saturday morning, my Ansul system would not turn the gas on or off. I called several companies looking for guidance/help and SOS was the only one courteous enough to help me troubleshoot the problem. Maureen not only was sympathetic to my plight, which de-escalated the stressful situation, she also walked me through the steps to get my gas up and running for business. My original fire company just blew me off, so now I look forward to using SOS for all my fire suppression needs. Taking the time to help shows the integrity of their service. Bravo!

We have a restaurant in Santa Monica and had a small fire incident from one of our fryers that activated our fire suppression system. We called SOS Fire Services and they responded very quickly. They took care of everything, got the system serviced and back up and running, and helped us avoid losing business and revenue. The technician was professional, knowledgeable, and explained everything clearly. We really appreciated the fast response, especially during a stressful situation. I Highly recommend SOS Fire Services for any restaurant fire suppression .
