WARNING
Ceiling, ceiling zone, floor and decompression range
When in decompression, it is important that you understand the meaning of ceiling,
floor, and decompression range.
The ceiling is the shallowest depth to which you should ascend when in
•
decompression. At this depth, or below, you must perform all stops
The ceiling zone is the optimum decompression stop zone. It is the zone between
•
the minimum ceiling and 1.8 m/6 ft below the minimum ceiling
The floor is the deepest depth at which the decompression stop time will not
•
increase. Decompression will start when you pass this depth during your ascent
YOUR ACTUAL ASCENT TIME MAY BE LONGER THAN
DISPLAYED BY THE INSTRUMENT! The ascent time will
increase if you:
•
remain at depth
•
ascend slower than 10 m/33 ft per minute
• make your decompression stop deeper than at the ceiling
These factors will also increase the amount of air required to
reach the surface.
