(a) Regardless of the approval status of the contracted organisation, the contracting organisation is responsible to ensure that all contracted activities are subject to hazard identification and risk management as required by ATCO.OR.C.001(c) and to compliance monitoring as required by ATCO.OR.C.001(f).

(b) When the contracted organisation is itself certified to carry out the contracted activities, the organisation’s compliance monitoring should at least check that the approval effectively covers the contracted activities and that it is still valid.
