Excessive grease buildup increases the fire hazard. Cleaning of the exhaust hoods should be based on the amount of grease buildup witnessed during inspections. Intervals between inspections and cleaning can differ, depending on the types and volumes of cooking that take place, the condition of equipment, and the efficiency of the hood filtration system.

Operational Compliance Tip: Table 12.4 provides minimum intervals for inspecting grease buildup in the hood and duct system. There are other features that should be inspected in an exhaust system, but those items might not need to be inspected at the same intervals.
