Explosives shall be piled and issued on a ______ basis.

Explosives shall be piled and issued on a ______ basis.

• A. first-in-first-out (FIFO)
• B. last-in-first-out (LIFO)
• C. random
• D. priority

Answer: (A)

Using the oldest stock first keeps explosives fresh and traceable. Explosives can degrade with time, moisture, or changes in packaging, so issuing the oldest lots first minimizes the risk of using expired or deteriorated material and helps ensure safety and reliability. FIFO also simplifies inventory records and inspections because you can clearly identify which lots were issued and when. Choosing a last-in-first-out approach would push newer stock into use before older stock, increasing the chance that older, more vulnerable material sits unused for longer and might deteriorate. Random rotation doesn’t guarantee aging control or traceability, which is essential for safety. Prioritizing by some criterion other than age ignores shelf-life and compatibility with storage requirements, undermining safe issuance. FIFO directly supports safe handling, compliance, and effective inventory management.
