Purpose of requirements

ISO 45001:2018 is designed to be applicable to any company, in any industry, in any location around the world. Since the OH&S legal requirements are different from company to company, and location to location, the ISO 45001 standard can’t dictate which laws are applicable, but for OH&S it is critical that you know the laws that apply to you, keep up to date when they change, and comply with these legal requirements. That is why the ISO 45001 requirement it to identify your applicable legal and other requirement, keep up to date on them, and ensure you meet them. You do not need to have a register of these applicable requirements, but this is one easy way to know the list of what is applicable and when it was last updated so that you know you are up to date.
