11.6.1* Following the inspection, the section of the exhaust system contaminated by grease deposits must be cleaned by a competent company or person(s) with appropriate training and certification recognized by the authorities having jurisdiction.

When to Clean

In accordance with NFPA96, a grease deposit gauge system is installed to notify when cleaning is necessary. The level is measured with a grease depth comb, shown here, which is scraped along the surface of the horizontal and/or vertical duct. A measured depth of 2000 microns (0.078 inch) indicates that cleaning is required to eliminate the risk of fire. The grease comb also includes a measuring point to indicate the high-risk zone, which is 3175 microns (0.125 inch). If the grease reaches this level, the 16-gauge galvanized steel ducts will not be able to withstand the heat produced by a fire and will open up, allowing the fire to spread freely.
