Unit Descriptor

Unit Descriptor 

This unit covers the competency required to act as a standby (air) diver in support of diving operations (both from a platform  and in-water) in an open water environment .

The diver will need to prepare and position the required diving equipment, and emergency resources, meet the readiness states as detailed by the dive supervisor, maintain communications with the supervisor throughout the dive, and take rapid steps to resolve incidents, ranging from the resupplying of emergency air reserves, to locating and rescuing injured or unconscious diver/s.

Note: This Unit of Competency covers the Australian Diver Accreditation Scheme (ADAS) occupational grouping of standby diver. 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 of Competency.

Application of the Unit

Application of the Unit 

The application of this unit in the workplace - the environments, complexities and situations involved - will be written during Phase II of the Review of the PUA00 Public Safety Training Package.

This text will be useful for the purposes of job descriptions, recruitment advice or job analysis; where possible, it will not be too job specific to allow other industries to import it into other Training Packages, where feasible.
