A maximum of how many days' supply of explosives may be stored in an issuing magazine?

• A. 7 days
• B. 15 days
• C. 30 days
• D. 60 days

Answer: (B)

Limit the amount stored in an issuing magazine to a manageable, trackable quantity so handling remains safe and inventory is easy to inspect. For an issuing magazine—the place where explosives are issued for use in blasting—the standard cap is 15 days’ supply. This keeps a balance between having enough material to meet work plans and keeping the stock small enough to reduce risk in case of an incident and to simplify security, accountability, and regulatory checks.

Storing only seven days would force more frequent replenishment and handling, increasing touchpoints and potential risk, while thirty or sixty days would create larger stockpiles that pose greater safety and accountability challenges and are not the typical limit for issuing magazines.
