Elements and Performance Criteria

1. Prepare to inspect and test rail signalling cable
   • Work health and safety (WHS)/occupational health and safety (OHS) requirements and workplace procedures for work area are identified, obtained and applied
2. Hazards are identified, risks assessed, and control measures and workplace procedures implemented
3. Safety hazards that have not previously been identified are noted on the job safety assessments and existing risk control measures implemented
4. Access times and work methods are confirmed to comply with customer requirements and relevant rail safety legislation
5. Rail service access is checked prior to testing and signalling cable is isolated/disconnected from rail network/equipment to ensure no equipment damage can occur during testing
6. Required inspection, test procedures and purpose are identified from site, client, workplace documentation and manufacturer specifications
7. Tools and testing devices needed for cable testing are obtained in accordance with workplace procedures and checked for correct operation and safety
8. Testing devices calibration certification is checked and current in accordance with manufacturer specifications
9. Inspect and test rail signal cables
   • Work area and rail cable system is made safe for testing in accordance with WHS/OHS risk control measures and workplace procedures
10. Rail signal cables are inspected in accordance with workplace procedures and relevant specifications
11. Tests are set up and performed in accordance with safety risk control measures and manufacturer specifications
12. Test results are read accurately and compared against manufacturer and site specifications for rail cable performance
13. Existing methods for dealing with unplanned situations are dealt with safely in a manner that minimises risk to personnel and equipment and with the approval of an authorised person/s
14. Testing is performed efficiently without waste of materials or damage to apparatus, the surrounding environment or services in accordance with sustainable energy practices
15. Available services are connected and tested for functionality to ensure all previous services have been resumed
    • WHS/OHS work completion risk control measures and workplace procedures are followed
16. Recommendations and required actions to maintain cable system integrity resulting from cable tests are reported and documented
17. Results of tests are documented accurately and in a timely manner to ensure test results remain current
18. Site and installation records are updated to ensure traceability of system information performance is maintained in accordance with workplace procedures
