23. Posting of permit-to-work

It shall be the duty of the supervisor or foreman of any person who carries out any high-risk work —

to clearly post a copy of the permit-to-work issued in respect of that high-risk work, including where reasonably practicable, a sketch of any area where the high-risk work is permitted, at the work area where the work is carried out; and

to ensure that the copy is not removed until the date of expiry or date of revocation of the permit-to-work or on completion of the high-risk work, whichever is the earlier.
