Course Overview

This course covers activities and competencies required for the training and certification of divers who are required to work safely and competently using Enriched Air Nitrox (EAN) using either SCUBA or surface-supplied breathing apparatus (SSBA) in accordance with the AS2815 training Standard.  It is designed to provide students with the skills required to dive using EAN in accordance with the AS/NZS 2299.1 Standard.

ADAS trainees and/or certified divers may be endorsed, after appropriate training and/or assessment, as competent to undertake occupational diving using EAN mixtures with SCUBA and SSBA.

The course can be undertaken either as a ‘top-up’ to any ADAS occupational diver training course, or as a stand-alone course for divers who already hold an ADAS certification but lack a Nitrox endorsement.

Course Standards

This course meets the requirements of:

  • AS 2815.1 Unit 14 (Using Enriched Air Nitrox)
  • AS 2815.2 Unit 12 (Using Enriched Air Nitrox)

Successful completion of the course results in a Nitrox endorsement being added to the diver’s ADAS card.
