NFPA 96 Standards & Hood Cleaning for Commercial Kitchens
This is a helpful overview of common NFPA 96 topics for commercial kitchens—especially around exhaust hoods, fans, grease containment, and cleaning frequency.
​
​​Important note: This page is for general information. Requirements can vary by kitchen type and your local Authority Having Jurisdiction (AHJ), such as the fire marshal or inspector. Always follow local guidance for your facility.
NFPA 96 is a fire safety standard focused on ventilation control and fire protection for commercial cooking operations. It’s widely referenced for best practices related to kitchen exhaust systems, including inspection, cleaning, and grease management.
NFPA 96 places responsibility for inspection, maintenance, and cleanliness on the equipment/system owner—unless that responsibility is transferred in writing to another party (such as a tenant or management company).
Cleaning frequency depends on cooking type and volume. Many kitchens are inspected at set intervals and cleaned when grease accumulation is found.
​
-
Monthly: Systems serving solid fuel cooking operations (wood/charcoal).
-
Quarterly: High-volume cooking operations (examples include 24-hour cooking, charbroiling, wok cooking, high-volume frying).
-
Semiannually: Moderate-volume cooking operations.
-
Annually: Low-volume cooking operations.
Best Practice Tip: Even if you follow a schedule, the real-world trigger is grease buildup. If grease accumulation is found upon inspection, the system should be cleaned by qualified personnel acceptable to the AHJ.
-
Kitchens that stay consistent with inspection, cleaning, and grease management reduce the chance of heavy grease buildup, help keep ventilation systems operating better, and stay more prepared for AHJ inspections.
