The cooking line is where kitchen fires start. We install and maintain wet-chemical suppression systems designed to stop them at the source.
Grease fires ignite fast and spread up into the ductwork where they're hardest to fight. A kitchen hood fire suppression system detects and knocks down a fire at the cooking line automatically — protecting your staff, your premises and the rest of your exhaust system before a small flare-up becomes a disaster.
A hood suppression system is built around the cooking line, not the room. Heat-sensitive detection (typically fusible links set above each appliance) holds the system armed; when the temperature over the cooking line passes the trigger point, the system releases automatically. Nozzles aimed at each appliance and into the hood plenum discharge a wet-chemical agent that smothers the flames and cools the grease so it cannot re-ignite. The same activation shuts off gas and electrical supply to the cooking line, so the fuel feeding the fire is cut at the same moment. A manual pull station lets staff trigger it by hand if they see a fire first.
Restaurants, food courts, hotel kitchens and central kitchens run the kind of sustained, high-heat cooking that a hood suppression system is built for — the busier the cooking line, the more grease-laden vapour reaches the hood and duct, and the faster a flare-up can spread. Commercial kitchens with significant cooking loads are generally expected to have suppression at the hood as part of their fire-safety provisions, and SCDF assesses this based on your premises, cooking type and layout. If you are fitting out a new restaurant, or an inspection has flagged that your kitchen has no suppression, we can assess the cooking line and advise what is appropriate before you commit to anything.
A clean exhaust system lowers fire risk; a suppression system contains the fire that still happens. Together with regular exhaust cleaning and fire-rated ductwork, suppression completes a layered approach to kitchen fire safety — the approach SCDF expects in higher-risk commercial kitchens.
There is no flat price for a hood suppression system. Cost is driven by the length of your cooking line, the number and type of appliances that need coverage, and whether we are fitting a system to a new hood or retrofitting one to an existing kitchen. We quote a clear figure after inspecting your cooking line — no guesswork over the phone.
A suppression system is only useful if it will actually fire when needed. We service the system on schedule so detection, nozzles and discharge stay in working order — and we document each service for your fire-safety records. See our dedicated fire suppression system maintenance & servicing for what a service visit covers.
For the background on why these systems matter and how they fit alongside exhaust cleaning, see our guide: Why kitchen hood fire suppression systems matter.
Suppression is the layer you hope never activates. We make sure that if it has to, it will.
