The correct answer is A. Audit findings that pose a significant health and safety risk.

In management system auditing practice, the audit team leader is expected to maintain communication with the auditee during the audit, especially when serious issues are identified. Where audit evidence indicates a significant risk , this should be communicated without waiting for the closing meeting , so the organization can take prompt action if needed. ISO guidance on conducting audits emphasizes communication during the audit and presentation of findings and conclusions at the closing meeting, while serious risks are handled immediately rather than being delayed. ( ISO )

Why the other options are not correct:

B. The outcome of the audit, including the conclusion is normally communicated at the closing meeting , not before it. ( Advisera )

C. Diverging opinions within the audit team are internal audit team matters. Only unresolved issues relevant to audit results may be raised appropriately, but internal team differences are not the key information to communicate beforehand.

D. Performance of individual workers when responding to health and safety-related questions is not the purpose of audit reporting. A management system audit evaluates the system and its implementation, not individual worker appraisal.

Therefore, the information that should be communicated to the auditee before the closing meeting is:

A. Audit findings that pose a significant health and safety risk.
