Ascent and exit

Emergency action


Begin your ascent along the descent line or anchor line.

Release air gradually from your BCD to maintain neutral buoyancy and prevent an uncontrolled ascent.

If a decompression stop is required, use a safety stop bar, descent line, or a suitable support system such as a redundant air source.

After returning to the boat, brief the next dive team on the bottom conditions and any important observations.
