Most of the BSAC reports have a summary of some sort. Typically it will be “like last year, most of these accidents would have been avoided if the people involved had followed their training”. Sometimes something new turns up, maybe medical as recently, but the tune isn’t changing.
So, the lesson for everyone, is follow your training. That might have not helped the bloke in this case, unless his training included “be sensible”. Of course technical training does include having the appropriate attitude.
Over the years, as a result of the analysis of the incident report, the training has been modified. Two elements that immediately come to mind are
1. The removal of buddy breathing from the training syllabus, and the emphasis on the use of AS (Alternate Source, or Octopus). This was as a result of the number of fatalities when air sharing (buddy breathing) in the event of a buddy running out of gas.
2. The positive exercise of dropping your and/or the casualties weight belt during rescue training. As a result of the number of divers that sank to the bottom after reaching the surface or having been brought to the surface in an emergency.
I have fallen over on a boat like this one. I thought I was extremely lucky not to smash my head open.
I had a regular dive buddy for a long time that amused many of us (despite his lack of a sense of humour).
He had originally enjoyed Sea Fishing (with a rod and line). He gave this up, two particular reasons.
1. Falling over on the deck of pitching boats - he had knocked himself out on more than one occasion.
(This amused me, knowing the story, watching him walk around on deck in full dive kit).
2. He suffered extreme sea sickness. - which was the primary reason he stoped fishing!
- On the back of that where his two solutions to sea sickness
a/ Eat Custard Creams (a British Biscuit), the reason, they taste the same coming up as they did going down.
b/ In a bad sea, he was the first in, and last out, even if the vis' was awful, and there was nothing but flat sand to look at.
(It minimised his period of sea sickness, he was ok in the water.)
