The space between the two tanks of secondary containment is called the _____.

• A. Gasket
• B. Interstice
• C. Plenum
• D. Cavity

Answer: (B)

Interstice refers to a narrow gap between two adjacent solid surfaces. In a secondary containment setup, the space separating the inner tank from the outer shell is this interstice—the gap that can contain leaks and be monitored. A gasket is a sealing strip, a plenum is an air-filled chamber for flow, and a cavity typically means a hollow area inside a single object, not the gap between two tanks.
