As agreed in the creation of this Training Package, applications for units transferred from the PUA00 Public Safety Training Package will be developed as part of continuous improvement plans, and taking into account the change in Unit of Competency format as detailed in templates for Streamlined Training Packages.
This unit covers the competency required to act as a lazy shot/bail-out operator and diver's attendant in an open water environment.
The lazy shot/bail-out operator's purpose is to mark the required decompression depth (through the use of the lazy shot) for ascending divers to service their decompression requirements. As part of the lazy shot rig, additional supplies of air (bail-out cylinders) are provided in the event that divers' personal supplies expire prior to surfacing. This can occur when multiple and/or lengthy decompression periods must be served.
The diver's attendant covers all aspects of assistance given to a diver in preparation for the dive, the conduct of the dive (such as management and monitoring of safety/communications lines) and the post-dive refurbishment of equipment.
Note: This unit covers the Australian Diver Accreditation Scheme (ADAS) occupational groupings of lazy shot/bail-out operator and diver's attendant in an open water environment. All information was correct at the time of development of this Unit of Competency; however, any diver seeking ADAS accreditation should consult ADAS and not rely on the information contained in this unit.
