A cadet is told that mast work needing height access, electrical isolation, and grinding will need more than one permit. Why isn't one permit enough?

A. Separate permits are needed only if different contractors are doing each task

B. One permit is enough as long as the job description mentions all three hazards

C. Multiple permits are only a company paperwork preference, not a safety requirement

D. Each hazard type — height, electrical, hot work — has different precautions, and combining them into one generic permit risks one of those precautions being missed or unclear

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
