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

• A. Within 12 hours
• B. Within 24 hours
• C. Within 2 hours not to exceed 8 hours
• D. Within 1 hour

Answer: (C)

Alcohol testing after a Marine Casualty must be completed within two hours of the incident, not to exceed eight hours. This window exists because alcohol is metabolized over time, so testing as close to the event as possible yields a more accurate reflection of the blood alcohol concentration at the time of the casualty. It helps ensure the evidence is meaningful for safety investigations and any potential administrative actions. Testing beyond eight hours becomes unreliable for determining impairment at the time, and the other suggested time frames either miss the critical early window or fall outside the approved period.
