A cadet, new to the permit to work system, is unclear on the basic purpose of a permit at all. What does a permit to work actually do?

A. It's a structured, predefined safety procedure that doesn't by itself make a job safe, but contributes to making the job safe by ensuring the location, hazards, precautions, and responsible people are identified and agreed before work starts

B. It's mainly a record for insurance purposes, with limited operational safety function

C. It guarantees that a job is safe once it has been signed

D. It's a legal document whose primary purpose is to assign blame if something goes wrong

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
