Elements and Performance Criteria

1. Identify and analyse causes of system and quality faults
   • Interpret alarm mechanism and make observations to determine fault type and location according to standard operating procedures (SOPs).
   • Conduct routine inspections of plant and processes to identify faults according to work health and safety (WHS) regulations and procedures, environmental and safe working requirements and practices.
   • Identify and deal with hazards according to safe workplace procedures.
   • Undertake required sampling and testing.
   • Interpret sampling and testing to identify variations from operating parameters.
   • Identify impact of fault on productivity requirements.
   • Access and interpret relevant sources of information to assist analysis.
   • Communicate information to relevant personnel.
2. Rectify systems and equipment faults
   • Shut down and isolate equipment prior to fault rectification according to WHS procedures, environmental and safe working requirements/practices.
   • By-pass faulty equipment where the process allows.
   • Repair or replace faulty equipment as required.
   • Make corrective adjustments to equipment.
   • Undertake operator level maintenance as required.
   • Verify restoration to normal operation and communicate to relevant personnel.
3. Rectify product quality faults
   • Identify product quality faults or variations by observation, inspection and testing.
   • Take samples for tests required to detect quality faults.
   • Interpret test results and adjust processes to correct variations from specification.
4. Record process performance and product quality data
   • Document variations from specifications.
   • Document performance variations.
   • Record corrective actions and communicate to personnel.
   • Dispose of out-of-specification product.
