Unit Of competency

Modification History

Release 1. This version was released with PMA Chemical, Hydrocarbons and Refining Training Package, Release 2.0.

Application

This unit describes the skills and knowledge required to operate and troubleshoot water treatment systems.

This unit applies to autonomous operators who are required to demonstrate an understanding of the process and the equipment operation in a plant with local control, or in liaison with the control-room operator in a plant with a centralised control panel.

This unit applies to an individual working alone or as part of a team or group and working in liaison with other shift team members and the control-room operator, as appropriate. In the case of a large, complex plant, the operations technician would be part of a team during startup and shutdown activities.

No licensing or certification requirements exist at the time of publication. Relevant legislation, industry standards and codes of practice within Australia must be applied.

Foundation Skills

This section describes those language, literacy, numeracy and employment skills that are essential to performance.

  • Learning skills to follow instructions, monitor process and select appropriate procedure.
  • Numeracy skills to monitor field data, instrumentation and process parameters.
  • Oral communication skills to liaise and coordinate with team members and the control-room operator.
  • Reading skills to follow written procedures and documentation.
  • Writing skills to complete workplace documentation.

Other foundation skills essential to performance are explicit in the performance criteria of this unit of competency.
