Rangehood Fire-Suppression Systems

New Application Fees $375 HOW TO APPLY


City Fire Department

Rangehood fire suppression systems are a key component to the overall safety of commercial kitchens and can be critical during the early stages of a fire emergency.

These systems are designed to protect ventilating equipment such as hoods, ducts, and filters. They also protect cooking equipment such as various types of fryers, griddles, range tops, broilers, and woks. Rangehood fire suppression systems are the first line of defense against commercial kitchen fires and promote the safety of life and property. It is imperative that Rangehood fire suppression systems are properly installed in accordance with the New York City Fire Code.

All new installations and proposed modifications / upgrades to existing commercial cooking fire extinguishing systems shall comply with the requirements of the 2022 New York City Fire Code (FC) §609 and §904.3.8, 2022 Building Code §904.12 “Commercial Cooking Systems”, and the referenced standards and listings, including but not limited to UL300 “Fire Testing of Fire Extinguishing Systems for Protection of Commercial Cooking Equipment”. The requirements for specific commercial cooking fire extinguishing system design can be found in the manufacturer’s manual for the desired installation and/or Certificate of Approvals for a device, equipment, or system requiring protection.

Relevant Fire Code Sections: FC609.6, FC904.1, and FC904.3.8.
