Safety Culture

What do you do when it all runs out?

I read a blog recently that suggested our egos could be responsible for many of the casualties that technical diving regrettably suffers. Sadly, my comments on this blog never made it past the moderator. As a scientist and psychologist, I am somewhat protective of terminology used to describe human thought, emotion and behaviour, and the author of this blog fell into a common trap in how one described ego.

There may not be an "I" in team, but there's one in "win", "live", "first" and "dive"!

Picture the scene: conditions are perfect, with flat seas and a clear blue sky. The atmosphere on the small boat is thick with testosterone and there is much whooping and hollering and backslapping as the six divers prepare their gear. The gauntlet has been thrown down. The challenge: to descend quickly down a reef wall to 90m on a single cylinder of air, collect a handful of sand and then come back to the surface.

How you can improve your performance and safety by understanding why we make good (and bad) decisions.

At those moments we are subjected to “peer pressure”, which is the social leverage that we feel when someone pushes us to behave in one direction or another. Usually, if we feel a good connection and a sense of balance with the other person (or persons) we are able to have our judgment override the social pressure—“No, David, I’m not diving five hours before we have to fly back!”

A diver had an oxygen toxicity seizure because an incorrect gas was filled in a cylinder by a dive centre. A baby died because the wrong dose of medication was injected. Who is to blame for the error and how do we try to make sure that these types of incidents aren’t repeated?

At the Rebreather Forum 3 conference held in Florida in May 2012, a number of presentations were made which advocated the use of checklists as a means to prevent diving incidents from occurring, or at least reducing the likelihood of occurrence.

In August 2012, I wrote an article which discussed just culture and what this meant in the context of recreational and technical scuba diving, and using this concept, how we can improve diving safety.
