The National Fire Protection Association (NFPA) is the governing body providing the minimum codes of standards for the kitchen exhaust cleaning industry via the NFPA 96: Standard for Ventilation Control and Fire Protection of Commercial Cooking Operations.

NFPA 96 reflects industry best practices that maximize protection of operators, building occupants, and property for reducing fire risks in public and private commercial kitchens.

Today more than ever exhaust hood cleaners require quality methods for maintaining grease-free exhaust systems to keep facilities protected from grease fires.

Kitchen Exhaust Cleaning Frequency Requirements:

Monthly Systems serving solid fuel cooking operations
Quarterly Systems serving high-volume operations such as 24 hour cooking, charbroiling or wok cooking
Semi – Annually Systems serving moderate-volume cooking operations
Annually Systems serving low-volume cooking operations, such as churches, day camps, seasonal businesses

Cleaning of Exhaust Systems

Upon inspection, if found to be contaminated with deposits from grease-laden vapors, the entire exhaust system shall be cleaned by a properly trained, qualified, and certified company or person (s) acceptable to the authority having jurisdiction.
