Safety Culture - diving in the zone
“Thank [beep] for that! How lucky were we? We better not do that again.
Don’t tell anyone though, we don’t want to look like amateurs...”

Diving is risky business. Just how risky depends on a whole shopping list of factors and influences, but let’s agree that there are more risks involved with diving than, say, sitting in your basement watching Olympic curling on TV.
Imagine scuba diving is a brand new sport. You hear about it for the first time when one of your friends tells you about a scuba experience she had recently on holiday and you think this sounds incredibly exciting. After thinking about it for a long time, you decide you want to learn. You take lessons to improve your swimming and then you look online for a dive instructor. There are no dive centres in your town.
Anna’s story: “I was on my eighth or ninth dive, about five minutes in and at a depth of around 13 metres when I realized that my air was not coming out smoothly. I couldn’t think why this should be. I had checked my pressure gauge on descent and it had shown 190 bar. I switched to my octopus, but there was no difference. Soon the air became very thin.
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.
A few weeks ago, a dive centre chartered a boat to take five divers and two instructors out to some islands off the south coast of Bali. It was rainy season and, behind the rainclouds, there would be a full moon that night in an area where currents are notoriously strong and unpredictable.
Being swept along on this technical diving thing, has been a long, somewhat twisted, but definitely entertaining journey. If you and I had met when the whole affair started, we could not possibly have envisioned how directly and pervasively, what were then radical activities, like cave diving, trimix diving and rebreather diving, would influence the mainstream dive community.
Is it the agency or the instructor that’s important?
The shark is an apex predator that has been on this earth for over 400 million years—a predator that, through the media and our deep-seated fears, has been systematically targeted and hunted throughout the world's oceans, pushing many species close to extinction.
In many cases, there is actually no plan to deal with a DCI incident. The rationale given runs along the lines of, “It hardly ever happens, so it is not worth thinking about until it does.”
