NFPA 96 Explained: What Restaurant Operators Actually Need to Know
A plain-English guide to NFPA 96 for restaurant operators. Covers cleaning frequencies, documentation, access panels, and common inspection citations.
What NFPA 96 is
NFPA 96 is the National Fire Protection Association's standard for the ventilation control and fire protection of commercial cooking operations. It is not a law by itself — it becomes enforceable when a state or local fire code adopts it, which most U.S. jurisdictions do.
Why it matters to restaurants
If your local fire code adopts NFPA 96 (most do), the standard dictates how your hood, duct, and fan system must be designed, inspected, and cleaned. Non-compliance is the most common reason restaurants are cited after a grease fire or insurance claim.
Core requirements
- Exhaust systems must be inspected at intervals ranging from monthly to annually depending on cooking volume and fuel.
- Cleaning must be performed by a properly trained person and must reach bare metal where practical.
- Access panels must be installed along the duct at required intervals so the entire system can be cleaned.
- Documentation of every cleaning — date, areas not cleaned, name of the service company — must be retained on-site.
- Rooftop or wall-cap fans must be hinged so they can be raised for cleaning beneath.
Most common citations
- Duct sections not cleaned to bare metal (often because no access panel exists).
- Missing or incomplete documentation of the last cleaning.
- Rooftop fan not hinged or not raised during cleaning.
- Broken or missing baffle filters.
- Cleaning frequency inconsistent with cooking volume.
Frequently asked questions
- Does NFPA 96 require a certified hood cleaning company?
- NFPA 96 requires a "properly trained, qualified, and certified" person. Most jurisdictions interpret this to mean a company whose technicians hold current IKECA or equivalent certification.
- What should I keep on-site for inspectors?
- At minimum: the most recent cleaning certificate, photo documentation if available, and a log of all cleanings for the past 12 months.
