Safety Tip

Rule of Halves

 
A new procedure is being suggested for safety stops by NAUI.  This is taken from an article in Dive Training Magazine (www.dtmag.com) for the month of  June 2003 (the contents says Page 18 but actually Page 16).  This is a new concept and is being mentioned here for "food for thought".  Dive Training Magazine is offered by many Dive Shops as a "freebee" and is one of the better magazines out there.

"For table-based no-required-decompression dives in excess of 40 fsw (feet salt water) [12 meters salt water], divers should halve the distance to the surface from the dive's deepest depth and make a 1-minute safety stop at that depth, followed by a 2-minute safety stop in the 15 fsw (5 msw) zone. For example, on a dive to 100 fsw (30 msw) the diver should make a 1-minute stop at about 50 fsw (16msw) and a 2-minute stop at about 15 fsw (5 msw)."
