The Master notices isolation handover failures appearing repeatedly in near-miss reports across the fleet. What systemic response is appropriate?

A. Take no action unless an actual injury results from one of the reported near-misses

B. Treat each occurrence as an individual lapse to be addressed only with the crew member involved

C. Treat it as a training and procedural gap rather than isolated forgetfulness — reinforce that isolation handover is a mandatory, logged step in the permit closure/handover process, not an informal courtesy

D. Conclude that isolation tags are an ineffective control and should be replaced with verbal handovers only

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
