Special Hazard Suppression Systems
Special Hazard Suppression Systems are fixed systems designed for specific hazards that conventional sprinklers or gas systems do not cover on their own, such as cooking-oil fires under commercial kitchen hoods and areas that need fire suppression with limited water. The category includes kitchen hood fire suppression systems and water mist systems. Selection follows the hazard type, the approved system design and the applicable code.

About this category
Special hazard suppression systems differ from sprinklers and gas systems in that each is designed and listed for a specific hazard together with its hardware. Kitchen hood fire suppression systems are installed over cooking appliances and inside exhaust ducts; they operate automatically through fusible links or detection and discharge a wet chemical agent that forms a soapy layer on hot oil and cools it, while shutting off gas or power to the appliances. Water mist systems release water as fine droplets through special nozzles at low, intermediate or high pressure, absorbing heat quickly and lowering oxygen locally with less water than conventional sprinklers; they are used in engine and turbine rooms, heritage buildings and data centres according to the system listing. Selection factors: hazard type and protected equipment, area dimensions, the system listing for the specific application, and integration with the fire alarm system. Design, installation and periodic maintenance must be carried out by an approved contractor. Specifications follow NFPA 17A and UL 300 for kitchen systems, and NFPA 750 and EN 14972 for water mist systems, together with local requirements.
