Elements and Performance Criteria

1. Locate and identify faulty components and blockages
   • Irrigation system and component function is determined by reference to system specifications and technical manuals.
   • Monitoring and maintenance records are checked and reviewed.
   • Operational tests are carried out according to system specifications, technical manuals and Occupational Health and Safety (OHS) requirements.
   • Faulty components and blockages are identified and documented according to enterprise policy and procedures.
2. Shut down/isolate component
   • Shut own sequence and isolation procedures are applied as required according to system specifications and technical manuals.
   • Safe shutdown or isolation is verified.
   • Safety/security lock off devices and signage is installed according to enterprise policy and procedures.
3. Replace faulty components and clear blockages
   • Access to faulty components and blockages is arranged.
   • Faulty components are removed from the system, according to system specifications and technical manuals, and repaired or disposed of in an environmentally responsible way.
   • Replaceable components are selected from manufacturer catalogues and procured using enterprise procedures.
   • Replacement components are installed to meet system specifications according to technical manuals.
   • Replace faulty components and clear blockages are carried out without unnecessary damage to surrounding site and structures.
   • Blockages are cleared or blocked sections replaced according to enterprise procedures.
4. Return system to normal operating status
   • Isolated or shutdown components are returned to service.
