Elements and Performance Criteria

1. Prepare to find and repair signalling system faults
   • 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.
   • Safety hazards that have not previously been identified are documented and risk control measures devised and implemented in consultation with appropriate personnel.
   • Appropriate persons are consulted to establish the nature of the fault and to coordinate effectively with others affected by the fault.
   • Likely causes of the fault and order of probability are determined from system data and historical trend.
   • Impact of the fault on system is ascertained and appropriate personnel notified in accordance with established procedures.
   • Materials needed to find and repair the fault are obtained in accordance with established procedures and checked against job requirements
   • Tools, equipment and testing devices needed to find and repair the fault are obtained in accordance with established procedures and checked for correct operation and safety.
   • Circuits/equipment are checked as being isolated where necessary in strict accordance operational procedures and OHS requirements.
2. Find and repair signalling system faults
   • OHS risk control measures and procedures for carrying out the work are followed.
   • Knowledge of signalling system performance parameters is applied to appropriate fault finding techniques.
   • Tests are conducted to determine the type and location of the fault.
   • Wiring system is visually inspected for physical damage or installation defects where necessary.
   • Methods for dealing with unexpected situations are selected on the basis of safety and specified work outcomes.
   • Ongoing checks of the signalling system are undertaken to confirm the continued rectification of the fault.
   • Faults are located and identified efficiently without waste of materials or damage to apparatus and the surrounding environment or services and using sustainable energy practices.
   • Signalling system faults are rectified in accordance with established procedures
3. Complete the finding and repair of the signalling system faults
   • OHS risk control measures and procedures for carrying out the work are followed.
   • Unresolved faults are reported to appropriate persons for further action in accordance with established procedures.
   • Inspection and test results actions taken or recommended are documented and appropriate person(s) notified in accordance with established procedures.
   • Documentation including component faults, test results, authorisations and permits is completed to provide an accurate database and facilitate follow up action, and relevant reports produced.

Evidence Required

The evidence guide provides advice on assessment and must be read in conjunction with the Performance Criteria Required Skills and Knowledge the Range Statement and the Assessment Guidelines for this Training Package The Evidence Guide forms an integral part of this unit It must be used in conjunction with all components parts of this unit and performed in accordance with the Assessment Guidelines of this Training Package

Overview of Assessment

Longitudinal competency development approaches to assessment such as Profiling require data to be reliably gathered in a form that can be consistently interpreted over time This approach is best utilised in Apprenticeship programs and reduces assessment intervention It is the industrypreferred model for apprenticeships However where summative or final assessment is used it must include the application of the competency in the normal work environment or at a minimum the application of the competency in a realistically simulated work environment In some circumstances assessment in part or full can occur outside the workplace However it must be in accordance with industry and regulatory policy Methods chosen for a particular assessment will be influenced by various factors These include the extent of the assessment the most effective locations for the assessment activities to take place access to physical resources additional safety measures that may be required and the critical nature of the competencies being assessed The critical safety issues inherent in working with electricity electrical equipment gas or any other hazardous substancematerial present a challenge for those determining competence Sources of evidence need to be rich in nature to minimise error in judgment Activities associated with normal everyday work influence decisions about howhow much the data gathered will contribute to its richness Some skills are more critical to safety and operational requirements while the same skills may be more or less frequently practised These points are raised for the assessors to consider when choosing an assessment method and developing assessment instruments Sample assessment instruments are included for Assessors in the Assessment Guidelines of this Training Package

Critical aspects of evidence required to demonstrate competency in this unit

Before the critical aspects of evidence are considered all prerequisites must be met Evidence for competence in this unit shall be considered holistically Each Element and associated performance criteria shall be demonstrated on at least two occasions in accordance with the Assessment Guidelines UEE Evidence shall also comprise A representative body of work performance demonstrated within the timeframes typically expected of the discipline work function and industrial environment In particular this shall incorporate evidence that shows a candidate is able to Implement Occupational Health and Safety workplace procedures and practices including the use of risk control measures as specified in the performance criteria and range statement Apply sustainable energy principles and practices as specified in the performance criteria and range statement Demonstrate an understanding of the essential knowledge and associated skills as described in this unit It may be required by some jurisdictions that RTOs provide a percentile graded result for the purpose of regulatory or licensing requirements Demonstrate an appropriate level of skills enabling employment Conduct work observing the relevant Anti Discrimination legislation regulations polices and workplace procedures Demonstrated consistent performance across a representative range of contexts from the prescribed items below Locate and repair different types of rail signalling system faults as described in and including Interpreting plans and specifications correctly Identifying and interpreting fault history Identifying faults efficiently Rectifying faults promptly using appropriate diagnostic techniques Minimising interruption to rail traffic and services Using testing equipment and tools correctly and safely Confirming the integrity of the signalling system Following relevant codes of practice Completing relevant technical reports records and Dealing with unplanned events by drawing on essential knowledge and skills to provide appropriate solutions incorporated in the holistic assessment with the above listed items Note Successful completion of relevant vendor training may be used to contribute to evidence on which competency is deemed In these cases the alignment of outcomes of vendor training with performance criteria and critical aspects of evidence shall be clearly identified
