Elements and Performance Criteria
- Prepare to disconnect electrical/electromechanical circuits, equipment and components
- OHS procedures for a given work area are identified, obtained and understood.
- Established OHS risk control measures and procedures are followed in preparation for the work.
- The extent of disconnection is determined from, job specifications, design drawings and regulatory requirements.
- Appropriate personnel are consulted to ensure the work is coordinated effectively with others involved on the work site.
- Materials needed for the safe disconnection of circuits, equipment and components are obtained in accordance with established procedures and checked against job requirements.
- Tools, equipment and testing devices needed to disconnect circuits, equipment and components are obtained in accordance with established procedures and checked for correct operation and safety.
- Perform disconnection of circuits, equipment and components
- OHS risk control measures and procedures for carrying out the work are followed.
- Where applicable on-track safety requirements are complied with to enterprise standards
- Visual inspection is carried out and all circuits, equipment and components are checked to ensure they are in accordance with manufacturer and systems specifications.
- Disconnecting work includes the isolation and removal of redundant wiring and the termination of altered wiring, checking and adjusting levels, checking indicators and system operation is carried out to organisation requirements.
- Methods for dealing with unexpected situations are selected on the basis of safety and specified work outcomes.
- Disconnection is performed efficiently without waste of materials or damage to apparatus and the surrounding environment or services and using sustainable energy practices.
- Find and repair faults
- OHS risk control measures and procedures for carrying out the work are followed.
- System and design faults are verified using appropriate technical information, fault finding and diagnostic techniques to identify faulty signalling equipment.
- Faulty signalling equipment is replaced, adjusted and secured in accordance with manufacturer specifications and organisation procedures.
- Methods for dealing with unexpected situations are selected on the basis of safety and specified work outcomes.
- Fault finding and repairs are carried out efficiently without waste of materials or damage to apparatus and the surrounding environment or services and using sustainable energy practices.
- Test and adjust remaining signalling circuits, equipment and components
- Finalise decommissioning work
