| Re: Pure O2 CCR Dive Time and Depth limits. Dave,
No insult taken and I don't completely disagree with you. The manual and regulations are all quite clear and written with safety as the utmost concern. As long as the manals are followed, safety is not an issue. As anyone who has served knows, there are should we say *stressful* times when a decision must be made to go outside the limits of what is provided by the manual and that is where hopefully good judgement balances the true importance of the decision to violate the procedure with the need to accomplish the task.
I feel though that we may have hijacked this thread and provided little useful input though.
If someone here can not answer the original question, I will call a buddy of mine who probably had a small part in writing parts of that manual and ask what the basis was for some of those limits.
