Elements and Performance Criteria
- Enter and leave the water
- Prevailing weather and water conditions are considered when assessing the safety of diving operations and a decision on whether to continue the dive is taken.
- Procedures when entering and leaving the water from the dive platform meet accepted diving guidelines and are in accordance with normal dive practices.
- Signals to the dive platform prior to descent and following ascent are conducted according to normal dive practices.
- Identify and harvest underwater and land seafood catch
- Assist in lifting and handling
- The limitations and suitability of winches with hydraulic and air motors for use on the surface and under water are understood and applied.
- The correct signs and signals are used during winch operations.
- Lifting equipment and ropes of the correct type and safe working load are selected and rigged, using the correct mechanical advantage for the load being lifted.
- Lifting bags are properly secured and used to raise an object and the load is restrained so that ascent is controlled.
- Slings, ropes and lifting bags are inspected and maintained and pre- and post-dive checks on lifting devices are carried out.
- Use basic hand tools and auxiliary equipment underwater
- A range of basic hand tools is used to complete simple tasks under water.
- Auxiliary equipment is used in underwater operations according to established safety standards and enterprise procedures.
- Tools are inspected for defects, maintained appropriately or set aside for repair, if necessary, and stored correctly after use.
- Apply underwater search and survey techniques
