A magazine shall always be kept securely locked with at least how many door padlocks?

• A. 2
• B. 1
• C. 3
• D. 4

Answer: (A)

The concept being tested is dual-control access for explosive storage. A magazine must be secured so that no single person can open it alone. Requiring at least two independent padlocks ensures that two authorized individuals (or two separate keys) must be involved to gain entry, reducing the risk of theft or misuse and increasing accountability. One padlock would let a single person unlock and access the contents, which isn’t acceptable. Using more than two padlocks would meet the standard, but the minimum required is two, making two the correct answer.
