Louisville Food Service Fire Suppression Compliance Checklist

Louisville Local Fire Code & NFPA 17 Requirements

Louisville follows the Kentucky State Fire Code, which adopts NFPA (National Fire Protection Association) standards for commercial kitchens. Your hood suppression system must comply with NFPA 17, which governs dry chemical systems, and NFPA 17A for wet chemical systems—the most common type in food service. The Louisville Fire Marshal's Office and Jefferson County Health Department jointly inspect systems; annual inspections are mandatory, and documentation must be on-site. Restaurants must have both a fixed overhead system (covering cooking surfaces, hood, and ductwork) and portable Class B and Class K fire extinguishers accessible to staff. All systems must be installed by licensed contractors and tagged with current service dates.

Critical Inspection Items & Hood System Compliance

Inspectors verify that nozzles are properly positioned above all high-heat cooking equipment (fryers, griddles, broilers, woks) and unobstructed. The hood canopy must have fusible links (temperature-sensitive devices that trigger suppression) rated between 130°F–165°F, and these must be sealed and intact—corroded or missing links are immediate violations. Ductwork must be clean and free of grease buildup, as this is both a fire hazard and can prevent the suppression system from functioning. The system's pressure gauge must show normal operating pressure, gauges should be calibrated annually, and all control valves must be properly labeled. Wet chemical systems require functional nozzles that mist the cooking surface without scattering burning oil, and manual pull stations must be clearly accessible and unobstructed. Documentation of the last professional service (within 12 months) must be available for review.

Common Violations & How to Avoid Them

The most frequent violations in Louisville food service inspections include missing or expired service tags (indicating the system has not been professionally maintained), corroded or loose nozzles, and inadequate coverage over cooking surfaces—especially at expansion kitchens or renovated areas. Grease accumulation in the hood and ductwork is a critical violation that prevents proper suppression function and increases fire risk; regular quarterly hood cleaning is essential. Staff are often untrained on when and how to activate the system or use portable extinguishers—violations occur when employees cannot demonstrate proper procedure. Blocked access to pull stations, obstructed nozzles from hanging utensils or equipment placement, and missing pressure gauges also trigger citations. To avoid violations, schedule professional inspections 30 days before your health department's annual review, maintain a service log visible in your kitchen, and conduct monthly staff training on evacuation and suppression procedures.
