Diving with the isolator valve closed, breathing from the wrong tank, taking in a mouthful of caustic cocktail, these are the sorts of tech diving incident reports which DAN collects and publishes.

DAN also assists tech divers with decompression sickness, coordinates evacuations, and researches tech diving fatalities to identify potential issues that may need resolving.

In this episode Peter highlights some of the cases divers have filed with DAN ... and asks us to remember them for our own diving safety.
