Seattle Food Service Fire Suppression Compliance Checklist

Seattle Fire Code Requirements for Kitchen Suppression Systems

Seattle adopts the International Fire Code (IFC) with local amendments, requiring all commercial cooking operations to install automatic suppression systems over cooking equipment, fryers, griddles, and broilers. Systems must comply with NFPA 17A (Standard for Wet Chemical Extinguishing Systems) or NFPA 13 (Standard for Installation of Sprinkler Systems) depending on hazard classification. The Seattle Fire Department conducts fire protection system inspections during initial business occupancy permits and at intervals specified in the fire code—typically every 1-3 years. All suppression systems must have visible signage indicating the type of extinguishing agent used, and emergency shutoff switches must be clearly marked and accessible.

Hood System Inspection & Maintenance Checklist

Hood filters must be cleaned or replaced according to manufacturer specifications and cooking volume—typically every 30-90 days for active kitchens. Ductwork should be inspected for grease buildup, which is a primary fire hazard; professional hood cleaning services often provide documentation required by the SFD. Dampers, thermostats, and manual pull stations must be functional and unobstructed. The suppression agent (wet chemical or dry powder) must be at full capacity, with inspection tags from certified technicians dated and visible. Test the manual activation switches monthly and document results. Ensure hood system interlocks with the kitchen exhaust fan so the fan automatically shuts down when suppression activates, preventing spread of flames.

Common Violations & How to Avoid Them

The most frequent violations cited by Seattle inspectors include expired or missing inspection tags on suppression cylinders, inadequate hood cleaning documentation, blocked access to manual pull stations, and failure to maintain current system service records. Many operators neglect to update inspection certificates after annual maintenance, which results in citations even if the system itself is functional. Grease accumulation in ducts beyond 1/8-inch thickness triggers automatic failures. To avoid violations, establish a maintenance calendar with certified fire protection contractors, keep all inspection reports on-site and accessible to inspectors, and assign staff responsibility for monthly filter checks and visual system inspections. Schedule professional hood cleaning quarterly or per code requirements, and maintain a binder with all compliance documentation dating back at least three years.
