SFIDIV306
Perform underwater work in the aquaculture sector


Application

This unit of competency describes the skills and knowledge required to perform underwater dive work in aquaculture environments, including entering and leaving the water safely, undertaking maintenance on culture, holding or other structures and vessels, using basic hand tools and auxiliary devices, restraining and lifting loads, and conducting underwater searches.

This unit applies to individuals who work as occupational divers in the aquaculture sector of the seafood industry.

Occupational licensing, legislative and certification requirements apply to this unit but vary according to state/territory requirements. Occupational diving is regulated independently by each state and territory work health and safety authority. Users are advised to check with the relevant authority to confirm current requirements.

1.2 Ensure that procedures during the dive, and when entering or leaving the water from the dive platform meet guidelines and are according to normal dive practices

1.3 Use signals to the dive platform before descent and following ascent according to normal dive practices

2. Maintain structures, vessels and equipment

2.1 Inspect and assess the condition of culture or holding structures and report any required action to the supervisor

2.2 Inspect and assess the condition of associated vessels, structures, plant and equipment and report any required action to the supervisor

2.3 Undertake appropriate maintenance according to industry or licensing body instructions and health and safety procedures

3. Assist in lifting and handling

3.1 Recognise the limitations and suitability of winches with hydraulic and air motors for use on the surface and underwater when undertaking winching operations

3.2 Use correct signs and signals during winch operations to communicate effectively with crew
