Elements and Performance Criteria

1. Prepare to install/maintain CBI rail equipment
   • 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 are implemented in preparation for work
3. Scope of installation/maintenance work is determined from job specifications, drawings and regulatory requirements
4. Materials needed for the installation/maintenance work are obtained in accordance with workplace procedures and checked against job specifications
5. Tools, equipment and testing devices needed for installation/maintenance work are obtained in accordance with workplace procedures and checked for correct operation and safety
6. Install/maintain CBI rail system
   • WHS/OHS risk control measures and workplace procedures for carrying out the work are followed
7. Reports or fault logs are identified by accessing diagnostic terminal
8. Fault correction activities are prioritised by reviewing the fault reports and previous corrective actions
9. Records of previously corrective actioned faults are deleted/cleared from the terminal
10. Source of the fault is identified by assessing the diagnostics terminal
11. Corrective action required is determined and implemented
12. Appropriate mechanisms for the safe and efficient rectification of the fault are determined
13. Methods for dealing with unplanned situations are determined on the basis of safety and specified work outcomes
14. Rail system monitoring is conducted efficiently, without waste of materials or damage to apparatus, the surrounding environment or services using sustainable energy practices
15. Replacement equipment is obtained from spare stock to comply with identified fault repair requirements
16. Faulty component/equipment is identified and removed in accordance with organisation practices and procedures
17. Replacement component/equipment is installed and connected to power in accordance with manufacturer specifications
18. Correct test procedures are identified and implemented to confirm all operations are within specifications
19. Equipment operations are monitored to ensure system integrity
20. Signal and voltage levels are monitored, checked and adjusted, as required, in accordance with operational requirements
21. Completed statistical records and equipment/operational management information are accurately recorded and maintained to support ongoing monitoring of systems and equipment performance
22. Complete CBI rail system installation/maintenance
    • WHS/OHS risk control work completion measures and workplace procedures are followed
23. Non-conforming equipment is identified and tagged for repair type and extent of fault is identified and recorded, as required
24. Faulty equipment requiring repair is segregated and appropriate records are completed in preparation for despatching to repairer
25. Spare equipment stocks are reviewed to ensure adequate availability
26. Priority for repair and/or replacement of equipment is determined by evaluation of stock levels and fault logs
27. Work completion is documented and appropriate person/s notified of repair and replacement priorities in accordance with workplace procedures and relevant reports produced
