The requirements of Part 4 of ROGS will apply to all dutyholders working on a transport system, for example, track contractors. Dutyholders with an established Safety Management System (SMS) must also detail how safety critical work is managed.  These dutyholders are known in Part 4 of ROGS as the 'controller of safety-critical work'.

Safety critical tasks must be carried out by a competent person, and include driving and dispatching trains, signalling, installation of components and maintenance, ensuring safety of persons working on the track (provision of protection), etc. Any worker carrying out safety critical work as part of practical training, for the purpose of obtaining experience towards developing competence as a safety critical worker, must be supervised by a competent safety critical worker.

Controllers of safety-critical work must have suitable and sufficient arrangements in place to monitor the competence and fitness of safety-critical workers.
