What is the method of containment called that involves placing a leaking container inside a larger undamaged one?

The method of containment that involves placing a leaking container inside a larger undamaged one is known as overpacking. This technique is particularly useful for safely managing and containing hazardous materials that are leaking or at risk of leaking. By enclosing the damaged container in a larger, intact one, overpacking helps to prevent the hazardous substance from escaping into the environment, thereby mitigating potential exposure risks and reducing the spread of contamination.

The overpacking process typically involves selecting a suitable outer container that is compatible with the substance being contained. This outer container must be strong enough to hold the inner container and any potential spill, providing an additional layer of protection. Overpacking is commonly employed during emergency response situations to safely transport leaking containers to an appropriate disposal or treatment facility.

While encapsulation, secondary containment, and retention each describe strategies related to hazardous materials management, they do not specifically refer to the act of placing a leaking container inside a larger undamaged one. Encapsulation generally refers to sealing off hazardous materials to prevent their release, secondary containment involves using structures designed to contain spills, and retention relates to mechanisms for holding liquids to prevent them from spreading.
