SPECIAL
DIVE TABLE AND COMPUTER PROCEDURES
You
may make a safety stop at the end of
any dive, and in fact, you should consider
it a standard practice on virtually
all your dives. However, consider a
safety stop required if:
1.
Your dive has been to 30 metres/100
feet or deeper.
2. Your pressure group at the end of
the dive is within three pressure groups
of the no decompression limit on the
RDP.
3. You reach any limit on the Recreational
Dive planner or your dive computer.
With a dive computer, this would be
if your computer shows zero NDL time
remaining at any point in the dive.
When
using the RDP, in these circumstances
the safety stop is considered required.
You may wonder whether you need to account
I for safety stop time when using the
RDP. You don't need to add safety stop
to your bottom time when using the Recreational
Dive Planner. A computer will process
safety stop time automatically.
Keep
in mind that, although you should make
safety stops a regular procedure for
all your dives, it's optional under
circumstances such as very low air (due
to unforeseen circumstances during the
dive), assisting another diver, or rising
bad weather make it more important to
get to the surface immediately.
Emergency
Decompression
You plan your dive as a no decompression
dive but emergency decompression stop
to allow your body to eliminate nitrogen;
without this stop, you face an unacceptable
of DCS when you surface.
