OHS documents, criteria and requirements

In answer to your questions regarding the ISO 45001 standard:

1. The ISO 45001 standard does not require a management representative, but also does not demand that you change your terminology. You can keep a management rep if you want, as long as all of the responsibilities in clause 5.3 are fulfilled by someone.

2. Clause 8.1.4 on procurement only requires that you establish a process to ensure that your procurement, including contractors and outsourcing, conforms to your OHSMS. How you do this is up to you, so including OH&S information into your standard contracts would be acceptable, as would an separate annex with this information; whichever works best for you. The idea of an annex that is only used for procurement where OH&S criteria needs to be flowed down might be the best approach.

3. Clause 8.1.4.2, Contractors, requires that you coordinate with contractors to identify hazards so that you can access and control the OH&S risks arising from the activities. So yes, you need to assess the risks of contractors to control the risks.
