Mine employee medical fitness standards require detailed examination, occupational testing, and certification for initial and periodical assessments. Medical examination requirements for mine employees are prescribed through a form for initial, periodical and re-examination purposes. The form records the employee's identity, findings of the examining authority and the opinion whether the employee is medically fit for mine employment, unfit for specified work, or requires treatment and re-examination. Detailed fitness standards are set for physical and mental health, vision, hearing, respiratory, cardiac, neurological, locomotor and other systems, together with specified laboratory, radiological and specialist tests.
