Support SCUBA diving operations from the surface
Assessment tool
Version 1.0
Issue Date: April 2024
This unit specifies the skills and knowledge required to support self-contained underwater breathing apparatus (SCUBA) diving operations from the surface by acting as a ‘lazy shot/bailout operator’ and/or diver’s attendant in an open water environment.
It includes preparing bailout cylinder, rigging ‘lazy shot’ and attending to SCUBA (air) diver/s from the surface.
The lazy shot/bailout 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 (bailout 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 managing and monitoring safety/communications lines) and the post dive refurbishment of equipment.
This unit was developed for Defence divers but may be applicable to anyone in this field.
The skills and knowledge described in this unit must be applied within the legislative, regulatory and policy environment in which they are carried out. Organisational policies and procedures must be consulted and adhered to.
Persons undertaking this unit work under supervision and perform specific tasks in a range of contexts that could be unpredictable.
No licensing, legislative or certification requirements apply to this unit at the time of publication.
