PUADEFDV003B - Act as a standby diver

PUADEFDV003B
Act as a standby diver

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

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.

Evidence Required

Critical aspects for assessment and evidence required to demonstrate competency in this unit

Assessment must confirm the ability to maintain readiness timings throughout the dive.

Consistency in performance

Competency should be demonstrated over a variety of tasks performing the duties of a standby diver at least twice and locating and recovering an unconscious diver from a depth of 20 m to the surface.

Context of and specific resources for assessment

Context of assessment

Competency should be conducted in the ocean supported by questioning on shore or aboard vessels.

When practicable, assessment should relate to the diver’s vocational focus.

Specific resources for assessment

Access to a complete range of diving, safety and accessory equipment; and a dive platform.

Guidance information for assessment

Information that will assist or guide assessment will be written during Phase II of the Review of the PUA00 Public Safety Training Package.
