Elements and Performance Criteria

1. Prepare to decommission electrical and electromechanical rail signalling from service
   • Work health and safety (WHS)/occupational health and safety (OHS) requirements and workplace procedures for a given work area are identified, obtained and clarified
2. Hazards are identified, WHS/OHS risks assessed, and control measures and workplace procedures implemented in preparation for work
3. Scope of decommissioning is determined from job specifications, design drawings and regulatory requirements
4. Appropriate safe working person/s is consulted to ensure work is coordinated effectively with others involved on the worksite
5. Materials needed for the safe disconnection of circuits, equipment and components are obtained in accordance with workplace procedures and checked against job specifications
6. Tools, equipment and testing devices needed to disconnect circuits, equipment and components are obtained in accordance with workplace procedures and checked for correct operation and safety
7. Withdraw electrical and electromechanical rail signalling from service
   • WHS/OHS risk control measures and workplace procedures for carrying out the work are followed
8. On-track safe working requirements are complied with in accordance with relevant industry standards and network rules
9. Inspection is carried out and circuits, equipment and components are checked to ensure they are in accordance with manufacturer and system specifications
10. Disconnecting, isolating and removal of redundant wiring; the termination of altered wiring; and checking indicators and signal system operation are completed in accordance with network requirements and relevant industry standards
11. Methods for dealing with unplanned situations are selected on the basis of safety and specified work outcomes
12. Decommissioning is performed efficiently, without waste of materials or damage to apparatus, the surrounding environment or services using sustainable energy practices
13. System and design faults are verified using relevant, technical information, fault-finding and diagnostic techniques to identify faulty rail signalling equipment
14. Faulty rail signalling equipment is replaced, adjusted and secured in accordance with manufacturer specifications and workplace procedures
15. Control equipment is adjusted, inspected and tested using workplace test procedures and equipment to ensure it operates in accordance with specified industry technical standards
16. Complete decommissioning work and reports
    • WHS/OHS work completion risk control measures and workplace procedures are followed
17. System faults are identified and reported for follow-up action in accordance with workplace procedures
18. Inspection and test results are documented in accordance with workplace procedures and faulty or replaced equipment is tagged and despatched to maintain equipment spares

Range Statement

Range is restricted to essential operating conditions and any other variables essential to the work environment. Non-essential conditions may be found in the UEE Electrotechnology Training Package Companion Volume Implementation Guide.
