Description
This unit involves the skills and knowledge required to apply absolute signal blocking (ASB) protection for the infrastructure and work group on a rail network during rail work activities by utilising a signal system managed by a network control officer, in accordance with Access Provider, legislative and regulatory requirements. Licensing or certification requirements are not applicable to this unit.
Notes
Elements and Performance Criteria
1 Prepare for absolute signal blocking protection
- 1.1 Worksite protection plan is sourced and read for the terms of ASB protection
- 1.2 Network control officer is notified of intention to use ASB protection
- 1.3 Protection officer is advised of network control officer's decision
2 Apply absolute signal blocking protection
- 2.1 Permission to apply ASB is requested from network control officer
- 2.2 Permission to apply ASB is documented in accordance with Access Provider and/or organisational requirements
- 2.3 Protection officer is advised that ASB has been applied
3 Ending absolute signal blocking protection
- 3.1 Communication is maintained with the network control officer to confirm completion of work activity and track is safe for rail traffic
- 3.2 Permission to remove ASB protection is documented in accordance with Access Provider and/or organisational requirements
- 3.3 Network control officer is informed of completion of work
4 Manage unsafe situations or emergencies
- 4.1 Unsafe situations and/or emergencies are identified
- 4.2 Work group is instructed to move to a safe place
- 4.3 Appropriate action is taken to minimise risk and/or injury in accordance with workplace procedures
- 4.4 Emergencies and/or incidents are recorded and reported to relevant personnel in accordance with workplace procedures
