My condolences to those affected by the loss of another diver. Always more than a diver. A real human being near and dear to others.
I like to address some specifics in this case not rebreather related, along with a recurring issue that continually comes up in this forum,
As distasteful as some may find it, it is important to keep in mind that ScubaBoard does not have an In Memorium or Condolences forum. This is an Accidents and Incidents forum for:
The purpose of this forum is the promotion of safe diving through accident analysis.
Readers beware, dont expect to find something else. Understand that legitimate points are sometimes raised in what is not the most appropriate fashion, but not necessarily out of malice either. It may be a manner, and a matter, of expression.
The manner in which assertions were made in regards to intelligence or lack thereof in this case may not have been the most appropriate, and certainly legitimate questions about this have been raised. Aside from this particular issue, the issues of diver ability, capacity to perform, or general knowledge and skill competency, are legitimate issues in accident analysis.
Im one who believes in a great deal of latitude when it comes to dive your way, as long as the implications are known, understood, and acceptable. Even so, certain practices, such as this one:
omar:
Case in point: On our dive trip he chose to dive in 38-42 degF water while wearing, in order, dive shorts, a womans one piece Speedo, dive skin, 5mm wet suit, & 7mm wet suit and on his head was a ladies old style dive cap and then a 5mm hood. He had to wear 48 lbs of lead in this setup. On the first dive he got uncomfortable about 16 minutes into the dive and bolted to the surface from about 30 feet. When I surfaced to find out what happened he insisted everything was okay and then submerged. I followed and keep my eye on him, I called the dive after about 45 mins. When we were sitting on the dock his lips were blue and he was shaking uncontrollably. I made him wait 2 hours until I was sure that he was warmed up before we did our second dive. During this period I pointed out the dangers of diving in cold water and at altitude for older guys (we were at 6550 feet). During this period I determined that he knew the dive tables and related material by rote but could not evaluate new situations or critically analyze a given scenario to determine the right or best course of action. Again on the second dive he displayed behavior that concerned me which I tried to talk to him about on the drive home and which he politely ignored.
Raise questions about how well the implications are understood. The last two sentences express, without great detail, the appraisal by omar that Harvey did not display in the related cases adequate capacity to understand and perform necessary practices needed to make a safe dive, as would probably be considered by most competent divers. Unfortunately, we dont know how well he understood the risks taken, and if he did, if they were acceptable to him.
Another legitimate issue is in regards to how Harvey went about obtaining training after other instructors who interviewed him in person had declined. There is the fact that most persistent persons can effectively buy a dive certificate, since the standards are set at such a low minimum level, and the important issue of competency or capacity to perform is largely left for instructors to subjectively evaluate. It is important to note that such training operating practices can and do cost injury and lives - even when no-one is legally at fault or in violation of standards. The issue goes beyond the immediate specific cause for this accident, into whether a lack of general inadequacy for consistent task performance was a contributing factor. A predisposition to higher risk. The higher the minimum non subjective codified standards of practice, the lower the cost - even if there will always be a cost. Something to be monitored.
That is one reason why, when I see an accident report here demonstrating poor training practice by an instructor, I recommend an official incident report be filed with the training agency. This will provide important feedback to agencies for instructor evaluation. It gives an agency the opportunity to identify consistently deficient instructors in order to effect remediation or termination. It also places some responsibility square on the agency based on knowledge, as a further incentive to take corrective action. In my opinion, this should be welcomed by all who prioritize and favor improving dive safety through training. I do believe enough information has been provided here to make this a relevant issue, which others are free to affirm or contest.
