Prime cartridges shall be exploded or utilized within how long after these are prepared?

Explanation:
Primed cartridges must be used while they are still within a safe, predictable state after preparation. The rule sets a precise maximum—they shall be exploded or utilized within 24 hours and 50 minutes after preparation. This specific limit balances practical blasting needs with safety, because as time passes the chance of deterioration, moisture effects, or unintended initiation increases. That exact window is what ensures compliance and safe handling, so it’s the best answer. Shorter timeframes (24 hours or about a day) don’t capture the full mandated limit, and a longer period (2 days) would exceed what the rule allows.
