Beyond delegating authorisation, what active oversight should a Master maintain over the ship's permit to work system as a matter of routine, not just after an incident?

A. Relying on the absence of reported incidents as the primary indicator that the system is working

B. Confirming once per voyage that the SMS document describing the permit system is up to date

C. Periodic review of the permit log for patterns (overdue closures, repeated extensions, near-identical permits raising similar issues), spot checks of permits in progress, and ensuring authorising officers are actually following separation-of-duties and closure requirements in practice

D. Reviewing permits only when specifically flagged by an officer as problematic

A. There is no fixed maximum — it depends entirely on the job

B. 48 hours, renewable once without re-inspection

C. 24 hours from issue, with any shorter job-specific time limits also stated on the permit

D. 7 days, matching the standard watch rotation

A. Accept the outgoing OOW's assessment and take no further action since the job scope hasn't changed

B. Cancel the job immediately without consulting the authorising officer

C. Wait until the 24-hour mark is actually reached before mentioning anything

D. Check elapsed time against the 24-hour limit, recognise it's close to expiry, and flag to the authorising officer that revalidation will be needed rather than letting it lapse unnoticed
