Application
This unit covers closed and semi-enclosed systems only (i.e. not open water). It does not include activities associated with electrical systems or supply. All enterprise or workplace procedures and activities are carried out according to relevant government regulations, licensing and other compliance requirements, including occupational health and safety (OHS) guidelines, food safety and hygiene regulations and procedures, and ecologically sustainable development (ESD) principles. Equipment operation, maintenance, repairs and calibrations are undertaken in a safe manner that conforms to manufacturer instructions. Appropriate personal protective equipment (PPE) is selected, checked, used and maintained. |

Overview of assessment | |
Critical aspects for assessment evidence required to demonstrate competence in this unit | Assessment must confirm the ability to: maintain and repair water supply and disposal systems and structures, including safely shutting down and restarting water supply and disposal systems and structures with minimal stress or damage to stock. Assessment must confirm knowledge of: general maintenance requirements for specific water supply and disposal systems or structures safe work practices techniques appropriate for the maintenance and repairs being undertaken. |
Context of and specific resources for assessment | Assessment is to be conducted at the workplace or in a simulated work environment, maintaining and making minor repairs to pumps, aerators and filters typically used in aquaculture enterprises in the region. Resources may include: hand and power tools and parts relevant to the water supply and disposal system or structure maintenance schedule and enterprise procedures manufacturer operation and service manuals water supply and disposal system or structure. |
Method of assessment | The following assessment methods are suggested: demonstration practical exercises project work written or oral short-answer testing. |
Guidance information for assessment | This unit may be assessed holistically with other units within a qualification. |
