The fact that the personnel safety requirements which were part of the ISO/TS 16949 standard are not required in the IATF 16949 should tell you something. They recognized it was not supposed to be part of a QMS standard. Since the IATF 16949 document is a supplementation to ISO 9001:2015, look in section 0.4 of 9001, where it states that the standard is not involved with occupational health & safety requirements.
The issue you are concerned with is outside of the scope of the QMS. Nevertheless, it is a reportable item. Auditors must react and report issues outside the scope of their audits when the situation warrants it. Especially when you are performing an internal audit. Everyone, at all times should report potential safety violations, undetected hazards, etc...
4.2 is about understanding the needs and expectations of interested parties and since the personnel and the government are interested parties. the compliance of safety standards is an expectation of both parties.
Read it carefully, because it clearly states "
that are relevant to the quality management system..."
