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
Elements and Performance Criteria
ELEMENT | PERFORMANCE CRITERIA |
1. Operate a surface supply panel | 1.1 Surface supply panel and associated equipment are inspected for serviceability and all gauges are checked to ensure that they are in-date. 1.2 Main and reserve air supplies are connected to the surface supply panel and supply is confirmed independently from each. 1.3 Seals and connections are checked for integrity, correct function and correct line-up. 1.4 Each umbilical from the surface supply panel is individually confirmed as supplying a specific diver. 1.5 Operator level maintenance on the surface supply panel is performed at the work site. 1.6 Surface supply panel is de-serviced after use. |
2. Conduct dive operations | 2.1 SSBA is selected, inspected for serviceability, fitted and tested (both out of water and in-water). 2.2 Dives are conducted using SSBA and dive contingencies are demonstrated. 2.3 SSBA is de-serviced and defects are reported in accordance with organisational procedures. |
Required Skills
This describes the essential skills and knowledge and their level, required for this unit. |
Required Skills |
conduct buddy breathing conduct ditching drills conduct lost buddy drills conduct unconscious companion diver drills fit and check SSBA identify distress and illness in others at depth inspect SSBA for serviceability and functionality monitor SSBA equipment and gauges recover and clear mask and mouthpiece refurbish SSBA post-dive switch from SSBA primary to the reserve air system |
Required Knowledge |

Evidence Required
Critical aspects for assessment and evidence required to demonstrate competency in this unit | Assessment must confirm the ability to: arrange for others to check equipment maintain equipment during the dive conduct in implement contingency and emergency drills including: buddy breathing ditching drills unconscious companion diver drills handle non handle non operate and maintain the surface control panel during the dive prepare equipment for the dive prepare the surface control panel for dive recover and clear mask and mouthpiece refurbish the surface control panel post refurbish equipment post safely enter and exit the water appropriate to the launch platform, equipment and conditions switch from primary to the reserve air system Consistency in performance Competency will be demonstrated over a minimum of 25 (ADAS Pt 2) dives and through the operation of the surface supply panel on four separate occasions that includes the following requirements: a range of surface and sub current (0–2 knots) day and night oceans, seas, lakes and rivers sub temperature (0 degrees +) visibility (0 metre +) Table 1 (below) outlines the minimum dives required by this Unit of Competency. At the time of printing, this contributed towards the achievement of an ADAS Pt 2 licence, however divers seeking ADAS licensing need to confirm details with ADAS. Table 1
The tables below are not relevant to this Unit of Competency but at the time of printing, contributed towards the achievement of an ADAS Pt 3 licence (SSBA diving to 50 metres). Divers seeking Pt 3 licensing need to confirm details with ADAS.
In 1 dive in the 33 to 42 metre depth range, remaining at the selected depth from the table below for at least the time in column 2 and conducting in water decompression for a simulated bottom time of at least that in column 3.
1 dive in the 42 to 50 metre depth range, remaining at the selected depth from the table below for at least the time in column 2 and conducting in water decompression for a simulated bottom time of at least that in column 3.

Context of and specific resources for assessment | Context of assessment Competency will be assessed in the ocean for all practical assessments, 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 complete range of SSBA diving, safety and accessory equipment. |
Range Statement
The Range Statement relates to the Unit of Competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording in the Performance Criteria is detailed below. | |
