Commercial Kitchen Fire Suppression (Hood Systems)
Commercial cooking operations require dedicated wet chemical suppression systems, not just sprinklers. Get matched with a contractor for design, installation, or service.
Overview
Commercial kitchens face a unique fire risk: grease fires burn hotter than water can safely extinguish and can flare back up if handled incorrectly. NFPA 96, the Standard for Ventilation Control and Fire Protection of Commercial Cooking Operations, along with UL 300 testing requirements, governs how these systems must be designed and installed.
A kitchen hood suppression system is a wet chemical, pre-engineered system installed over cooking equipment, inside the exhaust hood, and along the duct — the areas where grease accumulates and fire is most likely to start and spread.
Core System Components
- Wet chemical agent tank and piping network
- Nozzles positioned over each piece of cooking equipment, the hood plenum, and the duct
- A manual pull station near the kitchen exit
- An automatic fuel and electrical shutoff tied to system activation
- Detection typically via fusible links rated to the specific cooking equipment’s heat profile
Who Needs This
Any commercial kitchen with grease-producing cooking equipment — restaurants, hotels, hospitals, schools, correctional facilities, and commissary kitchens — is required by code to have a UL 300-compliant wet chemical suppression system, in addition to (not instead of) building sprinklers. If your facility also has server rooms or sensitive equipment spaces, see our post on clean agent vs. kitchen hood suppression.
Inspection & Maintenance
NFPA 96 requires semi-annual inspection of kitchen suppression systems by a certified technician, more frequently than the annual cycle typical for building sprinkler systems, due to the higher-risk environment.
Frequently Asked Questions
Is a kitchen hood system the same as my building sprinkler system?
No. Building sprinklers use water and are designed for general structural fire protection. Kitchen hood systems use a wet chemical agent specifically designed to suppress and prevent re-flash of grease fires, and are required in addition to sprinklers.
How often does a kitchen suppression system need inspection?
NFPA 96 requires semi-annual (twice-yearly) inspection by a certified technician.
What triggers the system?
Fusible links rated to the heat output of the specific cooking equipment they protect, which melt at a set temperature and release the suppression agent.
