What is the primary purpose of custody seals on MPPEH containers?

• A. They indicate hazard class.
• B. They provide chain-of-custody integrity and prevent unauthorized access.
• C. They certify the quantity.
• D. They determine storage location.

Answer: (B)

Custody seals on MPPEH containers exist to preserve chain-of-custody and prevent unauthorized access. They are tamper-evident and carry unique seal numbers, so you can see at a glance whether a container has been opened since it was sealed. Recording who applied the seal, who accessed the container, and when creates an auditable trail that holds personnel accountable and helps detect tampering. If a seal is broken or missing, follow the established procedures to investigate, document, and re-seal before the material proceeds. This purpose is distinct from indicating hazard class, certifying quantity, or determining storage location, which are handled by different labeling, measurement, or storage procedures.
