| As mentioned above the one thing that is really out of your control is a CO2 hit. I came very close to a cocktail the other week which was a wake up call.
What really worries me is screwing up. I think I am probably the biggest danger to my own safety, and I don't mean that flippantly. If you look at most risky activities, an awful lot of incidents, maybe most, happen because of something the participant does. I had a very near miss on sunday through complacency that made me stop and think. I've been gas diving for ten years (though playing on rebreathers for only two) and it shocked me how easily and simply I almost made it to the dive accident reports.
At the moment I think technology is fairly reliable. The big factor I've considered in moving to rebreathers is whether or not you can rely on yourself to do things right each time. There is not much margin for error or bodging things. I think I am still at the uptight, anal stage of rebreather diving, I haven't been doing it long enough to get complacent. That I suppose is my greatest fear because I am sure it will come as it is human nature and a combo of luck and skill as to whether or not you survive to learn your lesson.
Cheers,
