A young man of age 19 died recently diving in a cavern. We know the location, we know he had two buddies, we know he was diving beyond his training, we know someone tried to rescue him, we know he ran out of air. Facts and casual facts.
How did the discussion go?
Assuming these are researched statements whose truth has been verified beyond a reasonable doubt they can be accepted as facts. But what do they tell us? Very little. Now, what would we like to know if we are going to actually learn anything from an event such as this?
Here is a brief, by no means all inclusive, list:
-First, was this a Crime, an Accident, or Suicide? What facts and circumstances support the conclusion?
-Were drugs, including prescription, alcohol and OTC, involved? If so; what effect, if any did they have on the event?
-Was an autopsy performed? What was the result?
-Did the decedent have a physical problem that interfered with his ability to cope with the situation?
-Was his diving gear examined? Was it functioning correctly? Was it tested for any intermittent problems that might have contributed to the problem?
-Was the breathing gas tested to determine that it met purity and composition standards and was appropriate for the dive being undertaken?
-Was the reported rescuer interviewed to establish that in fact an attempted rescue was taking place and to see if rescue procedures were the best that could have been used under the circumstances?
-What facts support the idea that he was diving beyond his training? Has his diving history been investigated to the point that his formal and informal training has been determined?
-If it was established that he had no informal training then who was his instructor? Have the students from this instructor had similar problems in the past that maybe didn't result in a fatality?
-Since in SCUBA the instructor is also the evaluator, does the record show that the limits this diver was restricted to were clearly communicated to and understood by this diver?
-How frequently did this diver dive?
-Did he have a history of behaviour that would have made him prone to risky, unreasoned behaviour? Or, on the other hand, was he mature beyond his years and inclined to cautious, reasoned adventure?
Well, maybe the point is made by this short and incomplete list. Real accident analysis and education from that analysis is a time consuming, detailed process. It isn't until the process is complete, often months after the event, that the factual picture is painted. But it is that picture that provides the best information to guide others.
And, oh yes, there will be people who will not take the time to read the most carefully reasoned and prepared report and will still spout off with their favorite perspective, supported or not. After all this is the cyberworld. But, despite that I believe the scuba industry, mainly us, would significantly benefit from true accident analysis.
