Help DAN Track Dive Injuries

Allan Uribe, Dr.PH, MPH, CPH

Q2 2020

DAN has been tracking scuba-related incidents since the late 1980s, and the dive community is critical to our success in collecting information about fatal and nonfatal injuries. Our dive safety and medical experts have produced essential recommendations as a result of their in-depth analyses of incident data. What is critical for better data is for divers and others to report incidents to DAN. By collecting more data, DAN can continue toward the goal of making every dive accident- and injury-free.
