Ascent and exit

Emergency action


Start ascent along the descent and anchor lines.

Let the BC air be exhausted gradually without evacuating all at once, and be careful of blowing up and neutral buoyancy.

If a decompression stop is required, use a safety stop bar or a spare scuba set.


After going back to the boat, advise the next dive team about the seafloor situation.
