Elements and Performance Criteria
- Prepare to maintain operation of electrical mining equipment.
- 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 extent of work to be undertaken is envisaged from 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.
- Sources of materials that may be required for the work are established in accordance with established procedures.
- Tools, equipment and testing devices needed to locate faults are obtained in accordance with established procedures and checked for correct operation and safety.
- Maintain operation of electrical mining equipment.
- 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 measures devised and implemented in consultation with appropriate personnel.
- Fault finding is approached methodically drawing on knowledge of mining electrical equipment and circuits using measured and calculated values of circuit/apparatus parameters.
- Circuit/apparatus components are dismantled where necessary and parts stored to protect them against loss or damage.
- Faulty circuits/components are rechecked and their fault status and acquired.
- Materials/replacement parts required to rectify faults are sourced and obtained in accordance with established procedures.
- Effectiveness of the repair is tested in accordance with established procedures.
- Apparatus is reassembled, finally tested and prepared for return to service.
- Unexpected situations are dealt with safely and with the approval of an authorised person.
- Fault finding and repair activities are carried out without damage to apparatus, circuits, the surrounding environment or services and using sustainable energy practices.
- Complete and report on maintaining operation of electrical mining equipment.
- Note.Examples of documentation are component faults reports, test results, authorisations, permits, and parts/component dispatch and stores records.
