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.
SISOSCB307A Inspect and fill SCUBA cylinders.
Elements and Performance Criteria
ELEMENT | PERFORMANCE CRITERIA |
1. Operate an N2O2 compressor/ hand-booster pump | 1.1 Compressor and associated equipment are inspected for serviceability. 1.2 Protective equipment is fitted. 1.3 Leads and hoses are connected to the compressor. 1.4 Gas cylinders are charged to maximum working pressure and details are recorded in relevant logs. 1.5 Operator level maintenance is performed on the compressor. 1.6 Compressor is de |
2. Conduct dive operations | 2.1 CCBA (N2O2) is selected, inspected for serviceability, and fitted and tested (both out of water and in 2.2 Dives are conducted using CCBA (N2O2) and dive contingencies are demonstrated. 2.3 CCBA (N2O2) is de |

Required Knowledge |
CCBA (N2O2) dive equipment characteristics and limitations CCBA (N2O2) characteristics and limitations dive physics dive physiology and medicine general occupational/diving safety awareness hazards of nitrox marine animal threats marine hazards oceanography relevant references and Australian Standards safe operating ranges for air-supplies |
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 conduct in handle non implement contingency and emergency drills such as: buddy breathing ditching drills unconscious companion diver drills maintain equipment during the dive prepare equipment for the dive including charging of cylinders recover and clear mask and mouthpiece 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 15 dives with the diver diving to a depth not greater than 40 m using CCBA (N2O2) in open water that includes the following requirements: day and night oceans seas, lakes and rivers sub a range of surface and sub current (0–2 knots) temperature (0 degrees +) visibility (0 metre +). Table 1 (below) outlines the minimum dives required by this Unit of Competency. Table 1

Context of and specific resources for assessment | Context of assessment Competency will be assessed in the ocean over a range of oceanic, diurnal and nocturnal environments, 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 CCBA (N2O2) diving, safety and accessory equipment. |
