Safety stop
September 27th, 2007 Filed Under Uncategorized
A note on the “recommended safety stop.” We know that recreational no decompression limit (NDL) diving is “no decompression diving.” NDL diving does involve making a “safety stop.” How is a safety stop difference from a deco stop? They are both doing the same thing - letting the body deal with nitrogen bubbling out from an ascent, and to do it at a depth that keeps the bubbling under control for the body to off-gas it through the lungs for a given amount of time until enough nitrogen has been gotten rid of to make it safe to continue ascending.
Deco diving involves multiple deco stops at various depths in order to complete the ascent, and these stops are mandatory and with a glass ceiling. Even though NDL tables are set up so that a diver in trouble can bailout to the surface, whereas the deco diver has to deal with the problem at depth, I wonder if recreational divers often skip the safety stop because it is something that is recommended but not seem by them as being mandatory? My training emphasized that a safety stop is always part of the dive, so really all recreational dives are all decompression dives with a minimum 3 minute deco stop at 15 feet.
