It has long been the position of the American Academy of
Underwater Sciences that the ultimate responsibility for safety
rests with the individual diver. The time has come to encourage
divers to slow their ascents. |
| RECOMMENDATIONS:
|
- Buoyancy compensation is a significant problem in the
control of ascents.
- Training in, and understanding of, proper ascent techniques
is fundamental to safe diving practice.
- Before certification, the diver is to demonstrate proper
buoyancy, weighting and a controlled ascent, including a
"hovering" stop.
- Diver shall periodically review proper ascent techniques
to maintain proficiency.
- Ascent rates shall not exceed 60 fsw per minute.
- A stop in the 10-30 fsw zone for 3-5 min is recommended
on every dive.
- When using a dive computer or tables, non-emergency ascents
are to be at the rate specified for the system being used.
- Each diver shall have instrumentation to monitor ascent
rates.
- Divers using dry suits shall have training in their use.
- Dry suits shall have a hands-free exhaust valve.
- BCs shall have a reliable rapid exhaust valve which can
be operated in a horizontal swimming position.
- A buoyancy compensator is required with dry suit use
for ascent control and emergency flotation.
- Breathing 100% oxygen above water is preferred to in-water
air procedures for omitted decompression.
