What a Kitchen Hood Suppression System Does
A restaurant hood suppression system is a pre-engineered wet chemical system mounted in and above your exhaust hood. Nozzles are aimed at each cooking appliance, into the plenum, and up the duct. When heat melts a fusible link over the cooking line, or someone pulls the manual station, the system releases a liquid agent that knocks down the flames and reacts with hot cooking oil to form a soapy layer that helps keep it from reigniting. At the same moment it shuts off fuel or electric power to the appliances under the hood.
Because the system protects the most fire-prone part of the building, the fire code requires it to be serviced at least every six months and after every discharge, by qualified, trained technicians. It also has to match the appliances beneath it. Moving a fryer, adding a charbroiler, or switching cooking oil can mean the nozzles no longer cover the hazard.
- Required over appliances that produce grease-laden vapors
- Serviced every six months, plus after any discharge
- Must be redesigned when the cooking line changes

Restaurant Fire Suppression Questions
What is a kitchen hood fire suppression system?
It's a pre-engineered wet chemical fire extinguishing system installed in a commercial kitchen exhaust hood. Nozzles cover the cooking appliances, hood plenum, and duct, and the system releases automatically through fusible links or manually through a pull station, while shutting off fuel or power to the appliances.
Is a hood fire suppression system required in my restaurant?
Commercial cooking appliances that produce grease-laden vapors generally require a hood with an approved fire extinguishing system under the fire code your jurisdiction has adopted. Your local fire department or fire protection district decides what applies to your kitchen.
How often does a restaurant suppression system need to be inspected?
At least every six months by a qualified technician, and after any discharge. Owners should also do simple monthly visual checks. The kitchen fire suppression inspection page explains what each visit covers.
Are you a fire protection company?
No. STL Kitchen Suppression is an independent service-request and referral resource. With your consent, we pass your request to an independent fire protection provider that performs the work.
What areas do you take requests from?
St. Louis City, St. Louis County, and St. Charles County in Missouri, plus the Metro East in Illinois, including Belleville, Edwardsville, O'Fallon, and Collinsville.
My system went off. What should I do first?
Don't cook under that hood until a qualified technician has recharged and reset the system. Keep people away from the agent residue, and follow any direction from your fire department. Our guide on what to do after an Ansul system goes off walks through the first 24 hours.
