Australia National Standard for Health Assessment of Rail Safety Workers 2024 2.4: Risk categorisation process: follow the nine steps, define the context, identify rail safety tasks, analyse tasks into activities including rare emergency activities, analyse existing safety controls, categorise tasks with the Safety Critical and sudden incapacity tests, identify task-specific hearing, colour vision and musculoskeletal requirements using the Standard's decision figures, consider additional non-medical controls under the hierarchy of controls, confirm and document the assessment requirements on the template naming who decided, and implement, monitor and review whenever work practices or controls change; focus on tasks not grades, involve managers, workers and health expertise

What does 2.4 require?

The rail transport operator categorises its workers through a documented process. It defines the context (legislation, policies, the business and the operational environment such as safe-working and train protection systems and maximum speeds); identifies rail safety tasks rather than grades, since a multiskilled position takes the category of its highest-risk task; analyses each task into its activities and conditions, including infrequent emergency activities that are predictable; identifies the existing local safety controls such as safe-working rules, fail-safe systems, numbers of personnel and driver support devices; and categorises each task by asking whether ill-health could lead directly to a serious incident and, if so, whether sudden incapacity could, distinguishing risk from ill-health from lack of competence. It then identifies task-specific requirements: whether red colour differentiation is needed and, if redundancy or redesign cannot remove the need, whether point sources at distance or speed demand Normal Colour Vision or colour defective safe A vision, or surfaces demand colour defective safe B vision; whether the worker must hear speech in noise (60 dB or more) or in quiet; and what musculoskeletal capacity the task demands, such as walking on ballast, coupling, cab access and rapid movement clear of a train. Before settling on assessment, it considers whether additional procedural or engineering controls could reduce the health risk, applying the hierarchy of controls and preferring higher-order controls, and re-evaluates the task if they are introduced. It confirms and documents the matched assessment requirements on the risk categorisation template, recording who made the determination, shares it with the health professional, and implements, monitors and reviews the categorisation at least whenever work practices or engineering controls change. The process involves the responsible manager, the workers who do the tasks and suitably qualified health advisers.
