The three correct responses are A, B, and G.
A is correct because ISO 45001 Clause 5.3 requires top management to ensure that the responsibilities and authorities for relevant roles are assigned, communicated and understood at all levels within the organization, and that they are maintained as documented information. So if top management asks whether responsibilities and authorities for relevant roles have to be documented, the correct answer is yes.
B is correct because Clause 5.1 Leadership and commitment requires top management to ensure that the resources needed to establish, implement, maintain and improve the OH and S management system are available. Therefore, the auditor’s “Yes, you do” is correct.
G is correct because Clause 5.1 also requires top management to promote continual improvement. This is stated directly as part of top management leadership and commitment responsibilities under ISO 45001.
Why the others are not correct:
C is incorrect because top management does have to ensure that processes are established for consultation and participation of workers. Clause 5.4 makes this a requirement, so “No, you do not” is wrong.
D is incorrect as written. Top management must establish, implement and maintain the OH and S policy, but ISO 45001 does not state that top management personally has to “write” it. The wording in the option is too specific and not how the standard states the requirement.
E is incorrect because top management does have to ensure that the OH and S management system achieves its intended results. Clause 5.1 says this directly.
F is incorrect because top management must ensure OH and S objectives are established and compatible with the strategic direction, but ISO 45001 does not require top management personally to “write” the objectives.
H is incorrect because the organization must determine the scope under Clause 4.3, and top management remains accountable for the OH and S management system. Saying “No, you do not” is not correct in this context.
