As authorising officer coordinating a multi-permit mast job, the Chief Officer issues the height and hot-work permits but the electrician issues the isolation permit separately without telling the Chief Officer. What's the risk, and how should this be prevented?

A. This should be prevented by assigning all permits for a job to a single authorising officer regardless of their qualification for each hazard type

B. The risk is permits operating in isolation from each other with no one holding the full picture; this should be prevented by ensuring all permits for a single job are logged together in the master permit log and authorising officers communicate directly before any one permit is issued or closed

C. There is minimal risk as long as each individual permit is correctly filled out

D. The risk only matters if the job involves more than three separate hazards

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
