Unit Descriptor

Unit descriptor 

This unit of competency involves implementing a program for the operation, maintenance or upgrade of a system or facility using high technology water treatment components. Maintenance may be scheduled or emergency action, and upgrade may include expansions and retrofits.

The unit covers the review of records and the trial of new processes to improve performance. It also covers supervising staff, system or facility operations, conveying information, maintaining or upgrading high technology equipment and associated infrastructure, and overseeing the use of construction materials and tools.

No licensing, legislative, regulatory or certification requirements apply to this unit at the time of publication.

Application of the Unit

Application of the unit 

The unit applies to an aquaculture or holding facility in the seafood industry, or to an aquascape or holding tank in the ornamental or pet sector that uses a recirculating aquaculture system (RAS) with high technology water treatment components. The unit applies to personnel who have technical skills and supervise staff.

Construction or installation of systems or facility, cultured or held stock husbandry, harvesting and post-harvest activities are covered by other seafood processing, seafood sales and distribution, or rural production units of competency. Supervisory skills are covered by AHCWRK403A 4908A Supervise work routines and staff performance.

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.
