DEFDV003B
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 inwater) 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

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.


Prerequisites

DEFDV001B Dive using self-contained underwater breathing apparatus in open water to 30 metres.

1.3 Dive plan and reaction to incidents are confirmed with dive supervisor and task-readiness is confirmed in the designated medium.

2. Perform standby duties during the dive

2.1 Overall awareness of the dive operation including the status of deployed diver/s is proactively maintained with dive supervisor.

2.2 Incidents are responded to immediately.

2.3 Deployed diver is located via life-line or float-line.

2.4 Emergency air supplies are ferried to submerged divers.

2.5 An unconscious diver is recovered from under the water to the surface platform.

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.
