This Standard specifies the training activities and competencies required for the training and accreditation of divers who are required to work safely and competently-(a) using self-contained underwater breathing apparatus (SCUBA) to depths of 30 m (see Notes); (b) using surface-supplied underwater breathing apparatus (SSBA) to depths of 30 m (see Notes); and (c) on sites where no surface compression chambers are required by AS 2299 to be present on site. Requirements for full occupational diver certification and for restricted occupational diver certification are included.NOTES:1 Training and certification to this Standard is generally the minimum required to undertake diving in on-shore locations and construction activities, e.g. repair of jetties, dams.2 Restricted occupational diver certification is for persons whose diving duties do not require training in all of the specialized underwater tasks in Table 2.5 (see Clause 2.8). Divers with restricted certificates may only undertake diving operations which involve limited use of plant, tools and equipment.3 Attention is drawn to the requirements of AS 2299 and of regulatory authorities which limit the depths and times of diving with no compression chamber facilities. In particular, the requirements of regulatory authorities and AS 2299 generally prohibit the use of SCUBA for dives to depths greater than 30 m.4 Persons who wish to be trained sufficiently to dive to greater depths need to be trained to AS 2815.3. Graduates from training courses to this Standard, i.e. AS 2815.2, who wish to upgrade their diving qualifications may be eligible to do so by completing approved selected modules at an approved diving school.
