Question 3104 Deck General

The correct answer is C) 8 hours following the incident. Under the regulations for Serious Marine Incidents (SMIs), a mariner involved in an SMI is prohibited from consuming alcohol until after being tested or 8 hours following the incident, whichever occurs first. This is a requirement to ensure that the mariner's blood alcohol content can be accurately measured and assessed as part of the investigation into the incident. The other options are incorrect because they do not align with the 8-hour restriction specified in the regulations. Prohibiting alcohol consumption for only 2 or 4 hours would not provide enough time to properly test the mariner, while 12 hours would be overly restrictive.
