A kitchen fire suppression system is an automatic safety solution designed to detect and extinguish fires in cooking areas, especially those involving cooking oils and fats (Class K fires). It is critical for commercial kitchens in restaurants, hotels, hospitals, and food service establishments, but compact versions are also available for residential use. How the system works Most kitchen fire suppression systems operate automatically and work in a few key steps: Detection: A heat-sensing mechanism, like a pneumatic tube or fusible links, is installed within the kitchen's hood and duct system. When a fire causes the temperature to rise to a predetermined level, the link or tube will rupture. Activation: The change in pressure from the ruptured tube or the release of the fusible link triggers the system's main valve to activate. Many systems also include a manual pull station for staff to activate it immediately if they spot a fire. Suppression: The system discharges a fire-suppressing agent through a network of nozzles aimed at the cooking appliances, hood, and exhaust ducts. Fuel shut-off: Upon activation, the system can also shut off the gas or electrical supply to the cooking appliances to prevent re-ignition Clean-up: The wet chemical agent used is specifically formulated to make cleanup relatively simple, minimizing operational downtime.
