Kitchen Hood Suppression Inspection
Commercial kitchen hood suppression systems must be inspected and serviced every six months, without exception, regardless of system age or condition. Redbird handles the semiannual service including fusible link replacement, and coordinates around your service hours so the kitchen keeps running.
The work itself
- Verifying the agent tank has not discharged and the anti-reuse collar is intact, plus weighing the agent and expellant cartridge.
- Replacing fusible links every six months as a matter of course, not based on how they look.
- Inspecting nozzles and confirming caps and foil seals are present, and that nozzle placement still matches the appliances underneath.
- Testing the fuel shut-off, both gas and electric, because a suppression system that does not cut fuel is only doing half the job.
- Checking the manual pull station, detection line, and the interface with the building fire alarm where one exists.
Required intervals
| Interval | What happens | Who does it |
|---|---|---|
| Every 6 months | Full inspection and service of the suppression system by a qualified technician, including fusible link replacement and fuel shut-off testing. | Redbird |
| Ongoing | Hood and duct cleaning runs on its own schedule based on cooking volume and fuel type, which is separate from suppression system service. | Building staff |
The six-month interval comes from NFPA 96 and NFPA 17A. One detail worth knowing: if you have changed your cooking equipment since the system was designed, nozzle coverage may no longer match what is under the hood. That is a common finding after a menu or equipment change.
When we show up
- 01
We schedule around service, usually between meal periods or before opening, so we are not standing in the middle of a dinner rush.
- 02
The system is inspected, links are replaced, and the fuel shut-off is tested to confirm it actually drops the gas or power.
- 03
We check that nozzle coverage still matches the appliance lineup, and flag it clearly if the equipment has changed since installation.
- 04
You get a dated tag on the system and a report you can hand to the health inspector or fire marshal without translation.
Straight answers
- How often does a kitchen hood suppression system need inspection?
- Every six months, per NFPA 96 and NFPA 17A. That is two full service events per year with no exceptions based on the age or apparent condition of the system. Fusible links are replaced at each semiannual service.
- Is hood cleaning the same as suppression inspection?
- No, and this trips people up constantly. Hood and duct cleaning removes grease and runs on a frequency set by your cooking volume and fuel type. Suppression system inspection is a separate semiannual service of the fire suppression equipment itself. You need both.
- We replaced a fryer. Does that affect our system?
- It can, significantly. Suppression nozzles are aimed and sized for specific appliances in specific positions. Swapping, moving, or adding equipment can leave an appliance outside the designed coverage. Tell us when equipment changes and we will verify coverage still matches.
