The breathalyser test confirms alcohol above the permitted limit. What does the zero-tolerance policy typically require?

A. A confirmed positive test should simply be noted with no further action if the individual otherwise performs well

B. The test result should be kept entirely secret from the company, even though it confirms a policy breach

C. The result should be ignored if the individual is well-liked or long-serving

D. A confirmed breach of the drug and alcohol policy on a safety-critical role usually results in formal disciplinary action under the company's policy, which in many cases means removal from duty and can lead to dismissal — this is what "zero tolerance" generally means in practice, distinct from how an underlying substance use problem might be supported separately

A. Confront them aggressively in front of other crew members

B. Report your concern immediately to the officer in charge or master — do not attempt to assess "how drunk" they are yourself or decide whether it is serious enough to mention; this is exactly the kind of judgement call that should be escalated, not made informally by a peer

C. Quietly cover for them yourself without telling anyone in authority

D. Say nothing and hope they are fine to stand the watch as normal

A. Ignore the report entirely unless the individual visibly stumbles or shows obvious impairment

B. Make a personal judgement about whether they "seem fine" and allow the watch to proceed without any formal testing

C. Follow the ship's drug and alcohol testing procedure (commonly a breathalyser test, with results and chain of custody documented) rather than relying on a subjective assessment alone, and stand the individual down from safety-critical duty pending the result if there is genuine cause for concern

D. Immediately announce the suspicion to the entire crew before any testing has taken place
