ISO 45001 Clause 4.2 requires the organization to determine the relevant interested parties, their relevant needs and expectations (requirements), and which of those become legal or other requirements for the OH and S management system. Workers are explicitly central to ISO 45001, and the standard is aimed at providing safe and healthy workplaces and preventing work-related injury and ill health. Therefore, A. Workers requiring a safe environment in which to work is clearly a relevant requirement of a relevant interested party.

ISO 45001 Annex A.4.2 lists suppliers, contractors and subcontractors among examples of interested parties. Since externally provided products and services can affect OH and S performance, a requirement linked to minimizing the risk of harm in those products and services is relevant to the OH and S management system. That is why B. Subcontractor producing products and services that minimise the risk of harm is also relevant. It aligns with the standard’s treatment of contractors/subcontractors as interested parties and with operational control over externally provided products and services that can affect OH and S.

Why the others are not correct:

C. Competitors requiring information on the organisation ' s work environment is not a relevant OH and S requirement.

D. Top management requiring an annual bonus is a financial/personal issue, not an OH and S interested-party requirement.

E. Investors requiring maximum growth in return for their capital is a business expectation, but not a relevant OH and S requirement in this context.

F. Shareholders requiring guaranteed dividend payments is also financial and not relevant to the OH and S management system, even though shareholders may be interested parties in a broader business sense. ISO 45001 requires only the needs and expectations that are relevant to the OH and SMS to be determined.
