Application
The unit has application to cultured or held stock in an aquaculture, seafood holding or ornamental facility. The unit applies to personnel who have planning responsibilities and supervise the work of others. Skills in supervising and assessing the performance of staff are covered by AHCWRK403A 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. |
