In storage and inventory management for explosives, which records should be tracked?

• A. Expiration dates only.
• B. Chain-of-custody logs only.
• C. Location maps and temperature charts only.
• D. Expiration statuses and chain-of-custody records.

Answer: (D)

Tracking records in explosives storage centers hinges on knowing both how fresh the materials are and who has handled them. Expiration statuses tell you whether a given item is still within its safe and usable window, helping prevent the use of expired charges and ensuring compliance with safety and regulatory requirements. Chain-of-custody records provide a clear history of every transfer or handling event, which is crucial for accountability, loss prevention, and audit trails. Together, these two types of records give a complete picture: you can verify that materials are within their shelf life and that their custody history is documented and traceable.

Keeping only expiration dates misses who has possession and how the items moved, while relying solely on chain-of-custody logs omits whether the item is still within its safe operational period. Location maps and temperature charts are useful for storage conditions but don’t address currency of the material or accountability on transfers. Hence, the best choice is to track both expiration statuses and chain-of-custody records to maintain safe, compliant, and auditable inventory.
