Diving is not without risk—there is always a chance of death. There is always a latent or potential lethality within the “system”—where system is defined as the equipment, people and the physical, social or cultural environment. We cannot make diving 100 percent safe despite what anyone tells you. We can make things safer, but we cannot make diving safe.
Admittedly a rather contentious title, but it's supposed to be. Debates over whether diving, or even certain types of diving, are safe sometimes get emotive and heated, depending on the arguments being made. These include: Is closed circuit rebreather diving safe? How much safer is recreational rebreather diving than open circuit? Is cave diving safe? Is recreational diving to 18m on open circuit safe?
“…The real reasons people don’t provide a higher level of detail are two fold: privacy and legal culpability” was the response recently when I posted a blog about the need to collect more detail when looking at diving incidents so that the community, the agencies and academia can understand WHY incidents happen.
