As authorising officer, the Chief Officer is told a maintenance team has left for the day without formally handing over an isolation they applied. What should the Chief Officer do regarding that equipment?

A. Leave the matter for the team to resolve when they return the next day

B. Treat the isolation as still requiring a proper handover before any change of status — track down the team or formally extend/confirm the isolation through the permit system rather than letting the equipment's status sit ambiguous overnight

C. Instruct a different crew member to remove the tags so the equipment is available overnight

D. Assume the isolation can be safely removed since the working day has ended

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

B. 48 hours, renewable once without re-inspection

C. 7 days, matching the standard watch rotation

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

A. 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

B. Cancel the job immediately without consulting the authorising officer

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

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