ISO 45001: Defining the scope

Answer:
Clause 4.3 of ISO 45001:2018 includes a lot of requirements describing what to consider when determining the scope of your OHSMS, stating that the scope is the boundaries and applicability of your OHSMS. This can be confusing, but it is helpful to think of the scope of your management system as “where the rules of the management system apply”. So, for your company where will the rules, policies, processes and procedure that you put in place to promote occupational health & safety apply.
If everything you do is in one building, then this one building will encapsulate the scope of your OHSMS. If you have employees who travel to other locations for business, then these locations will be part of your scope since the OH&S rules apply to them as well. So, you need to look at all of your activities as a telecom provider and determine where your OHSMS information needs to be used.
