ADAS Occupational SCUBA to 30m qualification (Part 1)


This is the first level of certification as a commercial diver. It is intended to establish occupational scuba diving skills as part of the training for construction divers and is the occupational SCUBA qualification for police, marine archaeology, scientific research, media, and engineering inspection diving.

The qualification limits the diver to using hand tools or conducting inspections in no decompression dives with direct access to the surface. The diver cannot operate surface controlled power tools, or dive in operations where the use of overhead lifting or other similar activities is required.

If the trainee’s health has changed significantly since the medical certificate was issued, the trainee shall seek an appropriate medical review.
