Specifies the training activities and terminal objectives required for the training and accreditation of divers who are required to work safely and competently using self-contained underwater breathing apparatus (SCUBA) or surface supplied underwater breathing apparatus to depths of 20 m; and on sites where no surface compression chambers are required to be present on site or within convenient distance.
