Se7en:
Drive along the road at 100 and take you hands off the wheel for a couple of minutes - and you will die.
Go a couple of hundred meters into a cave with a single tank and run out of gas - and you will die.
Lie face down in the bath and don't raise your head to breathe - and you will die.
Seems that cars, OC scuba and bathtubs are not ready for "prime time" either by that logic.
No ECCR manufacturer would suggest flushing with Dil before ascent, no experienced ECCR diver would do so. I was just explaining why.
The fact that you could kill yourself by using the tool incorrectly doesn't in any way imply that the tool "is not ready for prime time". Suggesting as much just implies trolling.(Note" bolding added)
If you remove the word "
and" then the logic fails, so the issue is not the actual task but rather the inappropriate response. All you arguments are basically foolish because they take the form: "If you do something, anything,
and then kill yourself, you will die." A tautology, at best.
While the calculations are so trivial that any O/W diver should be able to do them, your assumptions are wrong, in at least two ways. First is the assumption that the diver will not make any further adjustments during a slow and methodical ascent after getting a read on the sensors (e.g., change the "
and"). Second is that the diver can't get to the surface conscious, with a blow and go ESE if need be, also clearly wrong (again, change the "
and"). If you are looking for ways to tack stupidity on reasonable procedure, there are many ways that you can do that, but post facto stupidity does not obviate the reasonableness of the initial response.
Your example requires that after flushing and determining the state of your sensors you tack on an "
and" and do something completely unconnected: that is to say, ascend without enriching. The problem is not with a diluent flush at depth, which has all sorts of things to recommend it as a one-size-fits-all emergency first response, the problems that you're looking at stem from a theoretical subsequent error glued on with an "
and".
AND by-the-way ... when diving be sure you don't hold you breath as you ascend. Get the idea?
...
The only point I wanted to make was that many things can be dangerous if used incorrectly.
Rebreathers are not dangerous if used correctly.
The same can be said of the silverware on your dinner table.
And using one correctly includes understanding how to monitor their continued function, and work around occasional failures.
Agreed.
I've known people who have died on rebreathers. I've also known people who have died driving cars. In both cases, each of them died due to running out of talent, not because the rebreather or car stopped behaving as expected.
Everyone I know who has died in an automobile accident did so as a result of experiencing a chaotic break in the linearity of their universe (which sometimes was the result of their running out of talent, sometimes was the result of mechanical failure that no amount of talent could survive and sometimes was the result of being in the unpredictable path of someone else's chaotic side trip, to blame all of those on the former is a bit presumptuous and border on blaming every plane crash (or rebreather death) on pilot error. That's wishful thinking and engineer-style denial.
Use your (rebreather / car / OC gear / bathtub) correctly and you will be fine.

Keep dreaming, keep denying, that make give you confidence up till your last moment ... but it will not delay your last moment one iota.
