WARNINGS and SAFETY RECOMMENDATIONS
• There are few legitimate excuses for making unplanned Decompression dives, and the conse-
quences of this type of diving can be severe. By making an unplanned Decompression dive
without the necessary preparation and training, you will have placed yourself in an unneces-
sarily dangerous situation. Allow a surface interval of at least 24 hours before reentering
the water in the event a dive requires emergency decompression.
• By entering decompression, you automatically impose a “ceiling” above you which you can-
not immediately ascend beyond, denying you free access to the surface.
• Existing data for making planned decompression dives is extremely limited, and virtually
nonexistent for repetitive decompression diving. Decompression diving greatly increases
your risk of decompression sickness.
• Decompression diving, or diving deeper than 130 feet (39 m), will greatly increase your risk
of decompression sickness.
• Special training, equipment, and support are necessary for diving deeper than the maximum
recommended sport diving depth limit of 130 feet (39 meters). Oceanic does not advocate
diving to depths below 130 feet (39 meters), the basis for which is purely theoretical.
