Commercial Kitchen Fire Suppression
Wet-chemical commercial kitchen and hood suppression systems with nozzle coverage, fuel/power interlocks, commissioning, inspection and maintenance.
Commercial-kitchen fires can develop rapidly because of high temperatures, cooking oils and grease deposits. A kitchen hood suppression system is more than a set of discharge nozzles; cooking appliances, hood and plenum, ductwork, exhaust fan, fuel or electrical isolation and manual-release functions must be considered together.
Protection Scope
- Fryers and cooking appliances
- Grills and ranges
- Hood and plenum
- Initial section of grease exhaust ductwork / required duct protection
- Manual release station
- Fuel and electrical interlocks
- Fire alarm system integration
Critical Design and Installation Issues
- Manufacturer-approved system design and nozzle arrangement
- Actual location and type of cooking appliances
- Hood and duct geometry
- Fuel and energy shutdown sequence
- Exhaust-fan and damper sequence
- Accessible location of the manual release
- Suitable and accessible cylinder/control-panel location
- Correct system restoration after maintenance
NFPA 96 and NFPA 17A Context
Depending on the project, NFPA 96 may be used for commercial-kitchen ventilation and fire protection and NFPA 17A for wet-chemical extinguishing systems. Manufacturer listing/approval requirements, local regulations and client requirements must also be considered.
Maintenance and Periodic Inspection
Maintenance should include nozzle caps, piping, cylinder/agent condition, detection elements, manual release, fuel or power shutdown and fan/interlock functions. Fire suppression system maintenance and hood/duct cleaning are different activities, and both are important to kitchen fire safety.
Service Area
From Yalova, DEMOFIRE provides commercial-kitchen suppression design support, installation, commissioning, testing, maintenance and service primarily across the Marmara Region, including Istanbul, Kocaeli and Bursa, and—depending on project scope—in Izmir and throughout Türkiye.
Frequently Asked Questions
Does a kitchen suppression system protect only the fryer?
No. Depending on the system design, cooking appliances, hood/plenum and relevant duct sections are protected together.
Should gas or electrical power be shut down when the system discharges?
A safe interlock sequence is an important part of the system design. The shutdown method depends on the project and the connected equipment.
Does hood cleaning replace suppression-system maintenance?
No. Hood/duct cleaning and suppression-system inspection, maintenance and testing are separate activities.
