NYC Kitchen Fire Suppression & Ansul Inspection
New York City, New York — 9 licensed inspectors found
New York City restaurants, bars, hotels, delis, and commissary kitchens need their wet-chemical kitchen fire-suppression system inspected and tagged every six months under NFPA 17A/96 and the NYC Fire Code. That tag is not a hood-cleaning sticker — grease-duct cleaning is a separate FDNY-certified trade and does not certify Ansul, Pyro-Chem, Range Guard, or similar suppression equipment.
NYC is stricter than most cities about who can touch these systems. FDNY requires the principal of any company that installs, inspects, tests, or services commercial cooking wet-chemical systems to hold an S-71 Certificate of Fitness, and every principal must also hold a NYC Department of Buildings Master Fire Suppression Piping Contractor (MFSPC) Type A or C license. The technician on site needs an S-17 Certificate of Fitness and works under the S-71 holder. Since July 1, 2023, each company may only service the manufacturers FDNY approved for it, and FDNY publishes that approved-company list monthly. Since October 1, 2023, the six-month service tag must also identify the COF holder who did the work, and the FDNY Rangehood Unit checks it. A HoodInspect listing is not FDNY approval — check the company and your system brand on FDNY’s list before you hire.

Who inspects kitchen fire suppression systems in New York City?
New York City commercial kitchens need an FDNY-approved wet-chemical company — not a hood cleaner — to inspect and tag their kitchen suppression system. The company principal holds an FDNY S-71 Certificate of Fitness and a DOB Master Fire Suppression Piping Contractor (MFSPC) Type A or C license; the technician on site holds an S-17 Certificate of Fitness and works under that S-71; and the company may only service the brands FDNY approved for it. HoodInspect lists NYC inspectors who service brands such as Ansul, Pyro-Chem, and Range Guard. Confirm the company and brand on FDNY’s approved list before you book.

Kitchen fire suppression FAQs in New York City
- How often does NYC require a kitchen suppression inspection?
- Every six months. FDNY requires the semi-annual inspection, testing, and servicing of a commercial cooking wet-chemical system to be done personally by an S-71 or S-17 Certificate of Fitness holder, in line with NFPA 17A and NFPA 96. FDNY inspectors look for a current service tag on the system. A hood-cleaning invoice does not replace that tag. See our six-month tag guide for what the visit usually covers.
- What certificate does an NYC kitchen suppression inspector need?
- Two layers. The company principal must hold an FDNY S-71 Certificate of Fitness for commercial cooking wet-chemical fire extinguishing systems, plus a NYC Department of Buildings Master Fire Suppression Piping Contractor (MFSPC) Type A or C license. The technician who comes to your kitchen must hold an FDNY S-17 Certificate of Fitness and work under the direction of the S-71 holder. Ask the vendor for both before you book. HoodInspect only shows certificate or license numbers we can match to an official source.
- How do I check if a company is FDNY-approved for my system brand?
- FDNY publishes an approved list of wet-chemical fire extinguishing system companies on nyc.gov and updates it monthly. It shows each company’s S-71 number and expiration, its DOB license type, and the manufacturers it is approved to service. Since July 1, 2023, a company may only work on the brands listed for it, so match the nameplate on your cylinder or control head (Ansul, Pyro-Chem, Range Guard, Kidde, Buckeye, and so on) to that company’s row before you hire.
- What must be on an NYC kitchen suppression service tag?
- Since October 1, 2023, the tag for a semi-annual inspection of a wet-chemical system must include information about the Certificate of Fitness holder who did the inspection (NYC Fire Code 904.5.2). FDNY Rangehood Unit inspectors verify that the work was done by a valid COF holder and may ask for proof of the technician’s training. If your tag has no COF holder information, ask the company to correct it before an inspection.
- Is FDNY kitchen suppression tagging the same as hood cleaning?
- No. Hood and duct cleaning is a separate FDNY-recognized trade: Commercial Cooking Exhaust System companies are certified by FDNY, and their principal holds a W-64 or P-64 Certificate of Fitness. That work does not cover the suppression system. The wet-chemical tag has to come from an S-71/S-17 company. Read our hood cleaning vs suppression guide if one vendor is offering both.
- Is an old dry-chemical or non-UL 300 kitchen system allowed in NYC?
- No. FDNY says dry chemical systems, wet chemical systems not listed to UL 300, and carbon dioxide systems may not be used for commercial cooking operations and must be removed and replaced with a system that complies with the Fire Code. If an older system is still over your line, an S-71 company can quote the replacement.
- Do NYC kitchens have to check the suppression system between inspections?
- Yes. FDNY expects a monthly visual check and a written record of it. Its study material tells COF holders to advise owners to keep at least one employee trained to do it, and recommends that an S-17 or S-71 holder train that person. The check covers whether the system is in place and undamaged, fusible links and detectors are clean, the manual pull station is unobstructed, gauges or panels show it is operational, and the maintenance tag is present and current. Keep a record with the date and the initials of whoever did it.
