Question 3094 Deck General

The correct answer is C) Saliva. The regulations for Serious Marine Incidents (SMIs) under 46 CFR 4.06 allow for the testing of a mariner's saliva for the presence of alcohol, in addition to the chemical testing of the mariner's breath. Saliva testing provides an alternative specimen that can be collected onboard the vessel, whereas blood testing would typically require transportation to a medical facility. The regulations do not permit the use of hair samples for alcohol testing in the context of a Serious Marine Incident investigation.
