Dive using self-contained underwater breathing apparatus in open water to 30 metres
Assessment tool
Version 1.0
Issue Date: July 2024
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 dive using selfcontained underwater breathing apparatus (SCUBA) in an open water environment to a depth of 30 metres.
The unit includes planning the dive (including using decompression tables); selecting, inspecting and fitting equipment; entry to the water from a range of platforms; conducting descent to, and servicing time at, the required depth; the ascent (including using decompression techniques); exiting from the water to the original platform; and removing and refurbishing equipment.
During the dive, divers must demonstrate situational awareness of their position and orientation, their equipment (including depth, time and air gauges), and other divers. They must be able to communicate (verbally by radio and nonverbally through signalling methods), to navigate underwater, and to manage the range of surface and subsurface hazards inherent to diving.
The unit also covers divers’ ability to perceive, both in themselves and others, the signs and symptoms of diving induced medical problems, and to take necessary corrective action/s; and to appropriately react to, and manage, a range of individual and group contingencies/emergencies.
Note: This Unit of Competency has been aligned with the existing standards of the Australian Diver Accreditation Scheme (ADAS). This Unit of Competency relates, in part, to the minimum standard for a diver using SCUBA to a depth of 30 metres. ADAS refers to this as ‘restricted’. Further experience is required to gain an ADAS ‘unrestricted’ rating.
Tables for both of these ADAS ratings are provided in the Evidence Guide. 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 only on the information contained in this unit.
