Portland Fire Suppression Compliance Checklist for Food Service

Hood System & Ductwork Requirements

Portland requires Type I commercial hoods over all cooking equipment that produces grease-laden vapors (fryers, griddles, broilers, ranges). Your hood must be UL-300 listed and equipped with properly labeled suppression nozzles—typically 1 per 2 linear feet of cooking equipment. Ductwork must be Class A rigid steel, sealed at all joints, and cleaned by a certified hood cleaner at intervals specified in your local fire code (usually quarterly). Verify that your makeup air system is properly proportioned and that all ductwork is inaccessible to pests. Common violations include missing or damaged nozzle seals, grease accumulation in ducts, and improperly sized replacement air vents.

Suppression System Inspection & Maintenance Standards

Your wet-pipe or dry-powder suppression system (typically ANSUL, Tyco, or equivalent UL-listed brand) requires a certified technician inspection annually and a formal discharge inspection every 6 years. Portland Fire & Rescue must be notified of discharge tests. Keep dated service tags visible on your system and maintain an onsite logbook of all inspections, recharges, and maintenance calls. Tank pressure gauges must read in the green zone; red needles trigger automatic citation. All nozzles, valves, and tubing must be free of corrosion, and your system must have a dedicated agent supply—mixing old and new agent types is prohibited and will fail inspection.

Common Violations & Clearance Rules in Portland

Portland inspectors frequently cite missing or expired inspection tags, inadequate clearance around suppression tanks (minimum 18 inches on all sides), and blocked access to manual pull stations. Your kitchen must have a clear, signed emergency shutoff for gas and electricity; these cannot be obstructed by equipment or supplies. Cooking equipment must be positioned to allow nozzle coverage—dead zones violate code and are major failure points. If you've had equipment moved, added, or replaced, you must schedule a pre-operation inspection with a certified fire suppression contractor before bringing it online. Document all modifications in writing and retain records for at least 3 years per Oregon requirements.
