ISO 45001: Procurement and contractors

Answer:
Clause 8.1.4 of ISO 45001:2018 is included in the standard to ensure that the process for procuring from external providers within your company includes controls so that the products and services you purchase meet the needs of your OHSMS, or in other words do your purchases consider occupational health & safety. The clause further discusses particular considerations for contractors and outsourcing separately, mainly because these are special types of procurement that require extra thought. Of course, the controls you will need to put in place will be dependant on not only your organization, but also the outsourcing or contracting you are using.
In general Outsourcing occurs at a supplier facility when they take on one of your processes, and this also requires you to ensure that these outso urced products and service meet your OH&S needs. Contractors will generally work within your facility, and need to understand your OH&S requirements as well as how they affect the OH&S of your facility. How do you ensure that contractors will not negatively affect your OHSMS when they are doing work, and how do you ensure that your do not negatively impact contractor safety when they are working?
