Which term describes placing a damaged container into an undamaged containment device?

• A. Overpacking
• B. Sealing
• C. Lining
• D. Encapsulation

Answer: (A)

Overpacking is the act of placing a damaged inner container inside an undamaged outer containment to restore and preserve containment for safe handling and transport. This creates a secondary barrier that prevents leaks from reaching the environment and helps the package meet regulatory requirements. The outer container must be intact and appropriate for the contents, often with absorbent material to capture any leakage and proper closures to maintain the seal.

Sealing a damaged container would not provide the necessary secondary containment around a compromised vessel, and wouldn’t reliably prevent release during handling. Lining refers to adding a protective interior layer but doesn’t describe placing one container inside another. Encapsulation involves immobilizing the contents within a solid matrix, which is a different containment approach from simply placing a damaged container into a strong outer package.
