Elements and Performance Criteria

1. Prepare to diagnose and rectify faults.
   • OHS procedures for a given work area are identified, obtained and understood.
   • OHS risk control measures and procedures in preparation for the work are followed.
   • The likely extend of work to be undertaken is envisaged from maintain procedures or fault/breakdown reports and/or discussions with appropriate person(s).
   • Advice is sought from the work supervisor to ensure the work is coordinated effectively with others.
   • Tools, equipment and testing devices needed to carry out the work are obtained in accordance with established procedures and checked for correct operation and safety.
2. Diagnose and rectify faults.
   • OHS risk control measures and procedures for carrying out the work are followed.
   • The need to test or measure live is determined in strict accordance with OHS requirements and when necessary conducted within established safety procedures.
   • Circuits/machines/plant are checked as being isolated where necessary in strict accordance OHS requirements and procedures.
   • Safety hazards resulting from the fault or breakdown are documented and risk control measured and devised and implemented in consultation with appropriate personnel.
   • Logical diagnostic methods are applied to diagnose lift system apparatus faults employing measurements and estimations of system operating parameters referenced to system operational requirements.
   • Suspected fault scenarios are tested as being the cause(s) of system fault.
   • Cause of the fault is identified and appropriately competent persons are engaged to rectify the fault where it is outside the scope of the lift systems.
   • Faults in the lift components of the system are rectified to raise apparatus and system to its operational standard.
   • System is tested to verify that the system operates as intended and to specified requirements
   • Methods for dealing with unexpected situations are selected on the basis of safety and specified work outcomes.
   • Diagnosis and rectification activities are carried out efficiently without unnecessary waste of materials or damage to apparatus and the surrounding environment or services and using sustainable energy practices.
3. Completion and report fault diagnosis and rectification activities
   • OHS work completion risk control measures and procedures are followed.
   • Reusable, faulty or worn components are tagged and dispatched for repair to maintain adequate spares.
   • Rectification of faults is documented in accordance with established procedures.
4. Note.Examples of documentation are components fault reports, test results, authorisations, permits, parts/component dispatch and store records
   • Appropriate person or persons notified, in accordance with established procedures, that the system faults have been rectified.

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 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 Industrys preferred model for apprenticeships However where summative or final assessment is used it is to 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 It is recognised that 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 nature of working with electricity electrical equipment gas or any other hazardous substancematerial carries risk in deeming a person competent Sources of evidence need to be rich in nature to minimise error in judgment Activities associated with normal every day work have a bearing on the decision as to how much and how detailed 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
