Are your kitchen exhaust systems NFPA 96 compliant? Do you know what your current grease (fuel) load is within your system? How does one measure grease build up, or even know when it exceeds safe levels? The NFPA 96 2014 Edition A.11.6.2 states that hoods, grease removal devices, fans, ducts and other appurtenances should be cleaned to remove combustible contaminants to a minimum of 50 pm (0.002 in). Okay, so how do we know when to clean? A measurement system of deposition should be established to trigger a need to clean. So, the Omni Grease Comb was envisioned.
“The method of measurment is a depth gauge comb which is scraped along the duct surface.” The NFPA 96 2014 edition states, a measured depth of 2000pm (0.078) indicated the need to remove the deposition risk. The Omni Stainless Steel Grease Comb measures 3 levels of cleanliness: acceptable – 50 microns (0.002 in), cleaning required – 2000 microns (0.078 In.), and critical levels – 3175 microns (0.125 In). Grease combs are a must have for individuals who are cleaning and/or inspecting kitchen exhaust systems such as Fire Marshals, Facility Managers, IKECA Certified Kitchen Exhaust System Cleaners, and any authorities having jurisdiction of the systems.
