Failures included anything that was not an effective provision of an alternative source of gas. That led to some fatalities, a few somewhat hurt people and some unhurt people. There were about 180 incidents over 5 or 10 years. I’d have to look on my proper computer to find the summary given by BSAC, if was on a now closed forum.Is AS "air sharing"? What does it mean for it to be a failure? Do all air sharing incidents get reported? I'm not in the UK, but it never occurred to me to report my buddy's OOA incident anywhere but here. Despite our initial struggles to free the octo, I'd call our air sharing a success. Are you saying most people who try to share air in a real emergency don't make it?
BSAC members are supposed to report incidents, they end up in an annual report and some analysis is done. Usually the conclusion is that people should dive as trained and follow the rules, recently it has brought IPO more attention.
If you don’t have a system to track how training turns out, how do you know whether the training is effective?
