Internal hood joints, seams, filter support frames, and appurtenances attached inside the hood shall be Sealed or otherwise made greasetight.

Internal hood joints, seams, filter support frames, and appurtenances attached inside the hood shall be Sealed or otherwise made greasetight.

• A. Sealed
• B. Open
• C. Accessible
• D. Welded

Answer: (A)

The key idea is preventing grease from leaking into hidden spaces inside the hood. When joints, seams, filter frames, and appurtenances inside the hood are sealed or made greasetight, they form a continuous grease-resistant surface. This containment minimizes grease buildup behind panels or in crevices, reduces fire risk, and makes cleaning and inspection more effective. The direct term used is sealed, which captures the requirement to create that grease-tight boundary. Welding could also achieve a greasetight connection, but the standard’s intent is met by sealing; choosing open would permit grease to escape, and accessible focuses on how easy it is to reach for cleaning rather than preventing grease from entering concealed areas.
