The Part 2 surface supply breathing apparatus program is to be a minimum of 4 weeks’ (that is, a minimum of 20 days over a 26-day period) training and assessment course to prepare Part 1 divers for certification as Part 2 construction divers.
This course is to prepare divers for work in the construction diving industry. The emphasis of the course is to develop competence in occupational scuba divers in:
- working safely and effectively as members of a construction dive team
- using modern surface supplied band masks and demand helmets with effective communications
- safely using a variety of pneumatic and hydraulic power tools
- a variety of demanding underwater construction and inspection and survey tasks.
The theory component of the course is to be conducted using the ADAS theory text and must meet the requirements of the ADAS Competency Standard.
All dives should be conducted using band masks or demand helmets and underwater communications.
Trainees are to be assessed on at least two occasions on the preparation of an effective risk assessment for dives involving relevant equipment and work tasks.
All dives should be conducted as no-decompression dives using primarily band mask and demand full helmets to include at least:
- a minimum of one demand full helmet and 10 band mask dives to ensure competency with both
- one zero-visibility dive (minimum of 20 minutes bottom time)
- one night dive
- 6 boat dives
- one dive to 28–30 metres
- lifting tasks using open and closed lift bags and utilising, in part at least, SWR and chain
- undertaking at least one underwater survey of a three-dimensional object that requires taking angular and linear measurements, and producing a written report that includes the correct description and recording of those measurements in an appropriate engineering drawing format
- standby diver training and assessment on SSBA as per the ADAS assessment pro forma
- undertaking at least one still photographic inspection and conducting at least one video quality control or safety surveillance work task
- at least 2 medium-to-long duration heavy construction project tasks involving team work, moving and assembling heavy components underwater in limited visibility, using buoyant lifts and manual labour, and following plans or drawings to achieve a reasonable degree of accuracy
- pneumatic tools (at least 2 out of drill, chisel, impact wrench, angle grinder, jack hammer)
- hydraulic tools (at least 3 out of chainsaw, angle grinder, disc cutter, impact wrench, drill, scrubber, rock drill, jack hammer) at 21–23 metres depth
- use of a hydraulic tool work task at a depth of 21–23 metres
- underwater cutting and welding
- the use of LP air jet and water lift/dredge
- a chamber dive to 50 metres. (Note: It is only necessary that trainees have 1 X 50 metre chamber dive per consolidated course (that is, a Part 1 and 2 combined or Part 1, 2 and 3 combined).
