ISO 45001 implementation minimal requirements

There is no set of “minimum requirements” to implement ISO 45001, every requirement in the standard (identified with the work “shall”) needs to be addressed. However, the requirements describe what needs to be done, but do not give details on how to implement them, because they need to be tailored to your organization. For instance,  ISO 45001 does not tell you what OH&S legal requirements you need to meet (since this will be different all over the world), but requires that you have a process to identify your legal requirements, keep up to date with changes to these requirements, and confirm that you meet the requirements.
