NFPA 96 is a standard set by the National Fire Protection Association (NFPA) that concerns the cleanliness standards for commercial kitchen exhaust systems. Grease vaporizes from a liquid to a gas during the cooking process and then solidifies inside the ventilation ducts, creating an incredible fire hazard. NFPA 96 outlines how often grease should be professionally removed from your system based on the volume of your cooking operation. This code also outlines what specific areas of the complete kitchen exhaust system should be cleaned.
NFPA 11.6.1 – “Upon inspection, if the exhaust system is found to be contaminated with deposits from grease-laden vapors, the contaminated portions of the exhaust system shall be cleaned by a properly trained, qualified, and certified company or person(s) acceptable to the authority having jurisdiction.”
NFPA 11.6.2 – “Hoods, grease removal devices, fans, ducts, and other appurtenances shall be cleaned to remove combustible contaminants prior to surfaces becoming heavily contaminated with grease or oily sludge.”
According to the U.S. Fire Administration, from 2011 to 2013 cooking was the leading cause of fires, accounting for 63.5% of all reported restaurant fires. Neglected kitchen exhaust systems have grease caked inside the ductwork, resulting in a disastrous fire when one aspect of the system catches flames. All kitchen exhaust systems, from the healthiest vegan kitchen to a country diner need to be cleaned at some point in order to avoid this fire risk.
How often you should clean you system depends on the cooking volume of your establishment. Table 11.4 below from NFPA Code 96 details how often your kitchen exhaust system should be cleaned by a professional based on cooking operation:
