Which factor determines how often kitchen exhaust systems should be cleaned?

• A. Building size and layout
• B. Cooking equipment type and menu selections
• C. Seasonality
• D. Color of walls

Answer: (B)

The main factor is how much grease and particulates the cooking operations produce, which depends on the type of cooking equipment and the menu. Fryers, grills, charbroilers, and other high-grease devices generate more grease that can accumulate in hoods, ducts, and filters, so kitchens with heavy frying or high-volume cooking need more frequent cleanings to prevent grease buildup, ensure proper airflow, and reduce fire risk. Menu selections drive this further: a menu heavy on fried or oil-based items increases grease production compared to non-greasy cooking. The other options don’t determine cleaning frequency in the same way. Building size and layout affect space, access, and maintenance logistics but not the rate at which grease accumulates. Seasonality might change demand temporarily but doesn’t change the amount of grease produced per hour. Wall color has no impact on grease production or buildup.
