What is the typical purpose of a duct cleanout?

• A. To seal duct sections.
• B. To mount sensors.
• C. To provide access for cleaning and removal of grease from duct sections.
• D. To connect to weather cap.

Answer: (C)

Duct cleanouts are access points that let maintenance crews reach the inside of the exhaust duct to clean and remove grease and debris. In a commercial kitchen, grease can build up on the duct walls, creating a fire risk and reducing airflow. A cleanout provides a removable section or door so tools can reach in, scrub or scrape away grease, and allow for inspection and removal of accumulated material. That direct purpose—providing access for cleaning and grease removal—is why this option fits best. Sealing duct sections, mounting sensors, or attaching a weather cap are different functions: sealing is about leaks during construction, sensors are installed in separate spots for monitoring, and a weather cap protects the outlet from weather, not for cleaning access.
