What is Kitchen Hood Fire Suppression?

Kitchen hood fire suppression systems are pre-engineered wet chemical systems designed to automatically detect and suppress fires in commercial cooking equipment. These systems protect deep fryers, griddles, charbroilers, woks, and the exhaust hood and ductwork above them.

When a fire occurs, the system automatically releases a wet chemical agent that rapidly knocks down flames and creates a foam blanket over the cooking media, preventing re-ignition. The system also shuts off gas and electrical supply to cooking equipment.

Code Requirement

NFPA 96 requires all commercial cooking operations to have an approved fire suppression system. Semi-annual inspections are mandatory.

Hood suppression workspace

Semi-annual hood work captured against the same system record.

System detail, deficiency capture, and report review live in one workspace. Nozzles, fusible links, gas valve, and tank pressure all feed the report from one row.

UL 300 system context (CaptiveAire, Ansul R-102, Pyro-Chem) carried in the asset record.
NFPA 17A and NFPA 96 citations pinned to the jurisdiction-adopted edition.
Deficiency-to-proposal handoff against the same asset.

Live demo: a real semi-annual hood inspection renders system detail, workspace state, and report preview from the same record without re-keying.

What this means semi-annually

The system detail, the inspection workspace, and the report preview are different views of one record — the semi-annual cycle does not require an export between tools.

Automatic Detection

Fusible links or electronic sensors detect fires instantly and trigger automatic suppression

Wet Chemical Agent

UL 300 compliant agents create a foam blanket that prevents re-flash of cooking oils

Equipment Shutdown

Automatic gas and electric shutoff prevents continued fuel supply to the fire

Authorized Distributor

The Kitchen Mister system uses a proprietary wet chemical agent delivered through specialized nozzles to rapidly suppress fires and prevent re-ignition. Known for reliability and ease of maintenance.

Key Advantage: Low-pH agent is gentle on stainless steel equipment, reducing cleanup costs after discharge

UL 300 listed wet chemical system
Automatic and manual activation
Mechanical or electrical detection options
Protected equipment includes fryers, griddles, ranges, and woks
Protects hood, plenum, and duct

Authorized Distributor

CaptiveAire offers two distinct system designs: CORE (Cylinder Over Range Equipment) for point-of-use protection and TANK systems for centralized suppression. Both feature 360° Firestat detection technology for reliable automatic activation.

Key Advantage: 360° Firestat detection provides superior fire sensing compared to traditional fusible links

CORE: Individual cylinder per appliance group
TANK: Centralized cylinder for larger kitchens
360° Firestat detection (not fusible links)
Integrated with CaptiveAire ventilation systems
Electric and gas shutoff capabilities
MAD Device (Mechanical Activation Device) for manual activation

Inspection Requirement

NFPA 96 requires semi-annual inspection of all kitchen hood fire suppression systems. Failure to maintain proper inspection records can result in fines, insurance issues, or closure by the Authority Having Jurisdiction (AHJ).

Inspection Schedule

Interval	Requirements
Monthly	Visual inspection by owner/operator: Check that system is armed, nozzle caps in place, manual pull station accessible, and no obvious damage.
Semi-Annual	Professional inspection required: Complete system examination including detection devices, nozzles, piping, agent cylinder, pressure gauges, and functional test of manual activation.
Annual	Full inspection with documentation review: All semi-annual requirements plus review of maintenance records, previous inspection reports, and any modifications.
5-Year	Internal cylinder examination or hydrostatic test per DOT requirements. Some manufacturers require complete agent replacement.
12-Year	Hydrostatic test of cylinders required. Many facilities choose to replace cylinders at this interval.

Semi-Annual Inspection Includes:

Verify system is properly armed and charged
Inspect all fusible links for damage or grease buildup
Check nozzle alignment and caps
Examine piping for leaks or damage
Test manual pull station operation
Verify gas/electric shutoff function
Check pressure gauge readings
Inspect detection line routing
Review and update inspection tags
Provide documentation for AHJ
