NFPA 96 is the standard the fire marshal is working from when they look at your kitchen exhaust — but almost no restaurant owner has read it. Here is the plain-English version of what it requires and why it exists.
NFPA 96 is the National Fire Protection Association’s "Standard for Ventilation Control and Fire Protection of Commercial Cooking Operations." In plain terms, it’s the rulebook for how commercial kitchen exhaust systems are built, maintained, and cleaned so they don’t start or spread fires. Most Texas jurisdictions adopt it by reference through the fire code, which is why your local marshal enforces it.
For an operating restaurant, the standard comes down to a few practical obligations:
NFPA 96 treats the exhaust as one connected system, and each part matters:
Grease is fuel. Every time you cook, a fine film of grease-laden vapor travels up the hood and through the duct to the fan. Left to build, that grease becomes a fire load running through your ceiling and roof — and a duct fire spreads fast and hot. NFPA 96 exists to keep that fuel from accumulating. The documentation requirement exists so inspectors and insurers can verify it’s actually happening.
Compliance is not complicated: clean the full system on your tier, keep the certificate current and on-site, and keep cleanout access clear. Putting the cleaning on a recurring schedule with one company is the simplest way to never fall out of compliance — and to have the paperwork ready the moment an inspector or insurer asks.
NFPA 96 is a standard, but Texas jurisdictions adopt it by reference through their fire codes, which makes it enforceable. Your local fire marshal inspects to it.
If you operate a commercial grease hood over a cook line, yes — regardless of size. Frequency scales with volume, so a low-use kitchen simply has a longer interval.
Assuming a hood wipe-down counts. The standard requires the full system — duct and rooftop fan included — cleaned to bare metal where accessible and documented.
It addresses fire protection for cooking operations, but the wet-chemical suppression system itself is inspected and serviced by a licensed suppression company, separate from hood cleaning.
