ADAS Occupational SCUBA Part 1

ADAS Part 1 Diving student underwater search using grid mesh

The ADAS Occupational SCUBA to 30m qualification (Part 1) is the first level of certification as a commercial diver. This course is a prerequisite for ADAS Part 2 (Occupational SSBA to 30m) and the theory component of this course explains to the student the role of a commercial diver allowing them to better understand the anatomy, physiology, physics and diving maladies related to occupational diving.

This qualification is most suited to divers conducting occupational dives for scientific, photography, media and inspection services.

The course competencies include:

  1. BSBWHS211 Contribute to health and safety of self and others
  2. NAT11006001 Work safely in hyperbaric operations
  3. NAT11006002 Maintain effective working relationships within dive or hyperbaric operations team
  4. NAT11006003 Apply knowledge of anatomy, physiology and diving physics to diving
  5. NAT11006004 Assess diving casualty and assist with first aid and treatment of diving illness and injuries
  6. NAT11006006 Utilise and maintain SCUBA equipment
  7. NAT11006007 Undertake pre-dive preparations for a SCUBA diving operation
  8. NAT11006008 Undertake underwater deployment in a SCUBA diving operation
  9. NAT11006009 Implement emergency procedures for SCUBA
  10. NAT11006010 Undertake post-dive procedures for a SCUBA diving operation
  11. NAT11006053 Perform underwater tasks using basic tools and visual techniques for a diving operation
  12. NAT11006054 Undertake a compression chamber dive
  13. NAT11006061 Contribute to health and safety in diving operations in compliance with legislation
  14. NAT11006062 Work effectively in the occupational diving industry
  15. NAT11006063 Use and maintain dive compressors
  16. NAT11006065 Apply knowledge of basic physics, anatomy, physiology and psychology to hyperbaric work

The ADAS Occupational SCUBA Diving to 30 metres (Part 1) course has a four (4) weeks / twenty (20) course days duration. The emphasis of the training is on preparing recreational SCUBA divers to work safely and effectively as members of a diving team using modern full face masks with effective communications to successfully achieve a variety of light work, inspection and survey tasks.

PDTA include Nitrox certification with all ADAS Part 1 Occupational SCUBA courses. The course includes 21 dives with tasks including full face mask orientation and emergency drills, standby diver rescue drills, underwater voice and lifeline communications, underwater searches, underwater surveys & photography, night dive, chamber dive, light construction/hand tool tasks and deep dives.
