USCG Exam PracticeChemical testing after a marine casualty
A marine employer suspects a crewmember of dangerous drug use based on behavioral indicators. Under 46 CFR §16.250, where practicable, the reasonable cause determination should be based on observation by whom?
- A. The vessel master alone, documented in the official logbook
- ✓ Two persons in supervisory positionsCorrect
- C. A Coast Guard commissioned or warrant officer
- D. The Medical Review Officer (MRO) and the vessel master
Why B is correct
46 CFR §16.250(b) states that where practicable, the reasonable and articulable belief that an individual has used a dangerous drug should be based on the observation of the individual by two persons in supervisory positions. A single supervisor's observation may suffice when two are not practicable, but the regulation's preference is for two supervisory observers.
