No, I haven't, and it's an interesting idea. Maybe it should be
required.

This is kind of what I was driving towards: if it is so important for
"some of the time", why isn't it applied "all of the time", when all
of the mix is coming from the same bank's Christmas Tree.


Anyway, maybe everyone who gets an OW card should
know how to analyze his or her gas, and I'm sure if you
pass that along to NAUI and PADI and the others they'll
take it under advisement.

While I agree that it would be a good idea, pigs will fly long before
PADI will "un-water-down" their OW class to require it. Such
knowledge of diving makes it harder, more technical and "scary", which
represents a consumer barrier. As such, its likelihood is effectively
zero.

FWIW, and I stand ready to be corrected, PADI was the second agency to allow Nitrox training w/ OW after IANTD.


Meanwhile, the reality today is that every Nitrox diver is
taught that its his or her responsibility to analyze his or
her gas in the tank before breathing it.

Yes, but it is within the context of an industry that require
liability waivers that includes waiving of rights even when *active
negligence* is present.


Failing that responsibility can have serious consequences, as
we've seen.

Precisely. As such, it is highly naive to believe for but one moment
that this policy has come about for any possible reason other than to
be one more mechanism to shelter the service provider from liability /
responsibility for his own shortcomings.

In other words, the approach is to blame the customer for not having
the due diligence to never trust the supplier (hence, 100% checks),
and we have mostly all swallowed that line of bull*** as acceptable,
because its ultimately our neck on the line.

FWIW, if we look over at a potential parallel in skydiving, I'm
curious as to how specifically does every customer perform a 100%
check on every chute that the professional chute-packer did indeed do
his job properly?
