Which term prevents grease passage under normal cooking?

• A. Greasetight
• B. Type I Hood
• C. Grease
• D. Duct Termination

Answer: (A)

Greasetight is the term used to describe joints and seals designed to prevent grease from passing through ductwork during normal cooking. In a kitchen exhaust system, air containing grease travels through hoods, ducts, and plenums, and any gaps or porous joints can allow grease to migrate into concealed spaces. A grease-tight construction uses sealed joints, gaskets, and properly rated sealants to keep grease contained, reducing fire risk and odor migration. Type I Hood focuses on capturing and removing grease from the air, not on sealing every joint. Duct termination refers to where the duct ends, not to preventing grease passage. Grease itself is the substance being transported, not the sealing property.
