Workers in Categories 1, 2 and 3 require a health assessment at Pre-placement and before changing to a position of higher risk category, to confirm initial fitness for the full range of inherent requirements of the job. Periodic Health Assessments for Category 1 and 2 Safety Critical Workers occur at commencement, then every 5 years to age 50, every 2 years to age 60 and every year after that, and regardless of the list a worker must be assessed within 2 years after turning 50 and within 1 year after turning 60. Category 3 workers are assessed at commencement and then every 5 years from age 40, with a full assessment less than 5 years before 40 able to start the clock from that date. These frequencies are minimums; an operator may assess more often where a rationale exists, and an existing condition that warrants more frequent review is specifically monitored at each periodic assessment. Triggered Health Assessments are additional assessments brought forward because a condition needs more frequent monitoring (the worker being Fit for Duty Subject to Review), because further investigation is needed to diagnose or treat a condition, because the operator has concerns from indicators such as recurrent absence, repeated incidents or traumatic events, or because the worker asks for one; the operator requests the assessment and provides sufficient information but does not determine its extent, which the Authorised Health Professional or Chief Medical Officer decides, and a triggered assessment does not reset the periodic schedule unless it was a full assessment.
