Accident Database and Reviews with analysis, 11th Nov 2011
The public extract of the Comprehensive Database of Rebreather Fatal Accidents and analysis, of 253 confirmed sports rebreather fatal accidents.
Manufacturers can use this data to improve designs, instructors can use it to improve training, and divers can learn from it too.
This list deviates from previous practice in that it contains names of all divers where these are in the public domain, to enable the accuracy of the list to
be verified more easily.
