Our Procurement Guide to ISO 45001 is for supply assessment for EHSQ management systems.  It includes both guidance, checklists and templates for creating pre-qualification systems, also usable for ISO9001 and ISO14001. The competence of contractors or outsourcers can be verified.  The meanings and definitions are given for all those responsible in the supply chain, such as contractors, workers, interested parties and outsourcers. The supply chain can undermine the intended outcomes of client and procuring organisations by bringing risks and hazards into the workplace or by their inadequate OH&S performance.  You can use the Guide to help top management and other interested parties understand their roles, responsibilities and accountability.
