During a Marine Casualty, what is the time limit for drug testing?

• A. Within 12 hours
• B. Within 24 hours
• C. Within 32 hours
• D. Within 48 hours

Answer: (D)

The question tests the time frame allowed to initiate drug testing after a Marine casualty. The best answer is within 48 hours because casualty procedures set a 48-hour window to initiate and complete toxicology testing for personnel involved. This window helps ensure specimens are collected while still reliable, maintains proper chain of custody, and aligns with the time needed for notification, transport, and lab processing during an investigation. Shorter windows—such as within 12, 24, or 32 hours—could miss testing due to delays in reporting or collecting samples, whereas 48 hours accommodates those real-world factors.
