Elements and Performance Criteria

1. Identify and analyse causes of faults
   • Check workplan according to documentation and procedures, workplace health and safety (WHS) procedures, productivity requirements, risks and hazards identification, environmental workplace procedures, standard operating procedures (SOP) and house keeping requirements.
   • Check availability of materials and supplies.
   • Use alarms and visual checks on water systems to determine fault type.
   • Interpret sampling and testing results to identify deviations from specifications.

   • Access relevant sources of information to assist analysis.
2. Rectify plant and equipment faults
   • Shutdown equipment and implement isolation procedures, prior to fault rectification, as required.
   • Identify, repair or replace faulty equipment.
   • Adjust process and carry out operator level maintenance.
   • Return plant and equipment to normal operations.
   • Verify restoration to normal operations and communicate to relevant personnel.
3. Rectify water quality faults
   • Identify quality faults or variations by observation, systematic sampling and testing.
   • Take samples for a tests to detect quality faults
   • Interpret test results and make operational adjustments, as required.
