What a great example of what I've been talking about - how the "O2, the
invisible killer" crowd", when asked for substantiation, always comes up
with horror stories that are about anything BUT diving. The oxygen
generators mentioned are actually pyrotechnic devices - they work by
igniting and producing O2 by intense heat. So that tragedy has little to do
with O2, and nothing at all with diving.
So your argument reduces to "since these people broke some regs and a lot
of people got hurt anyone else breaking or encouraging others to break any
reg is guilty of attempted murder." Or something like that.

Get real. Surely you have been around long enough to know that there are
all kinds of regs, some bullshit, some essential, and it requires constant
questioning and examination to tell the difference, and to pare away the
dumb ones, before we are inundated by them.
PADI had a reg until recently that PADI cave divers must wear snorkles.
Would you argue the fact that it was a PADI reg made it right, and as valid
as not loading pyrotecnic oxidizers into the cargo hold of a passenger
airliner? Most of the O2 "regs" we are discussing here are not real laws,
but just something, like the PADI idiocy, that someone at a self-appointed
tech agency thought was a good idea - or a way to sell more stickers.
One way we can tell if a reg is valid to to compare the results obtained by
following or not following it. In some cases this is hard to do, without
blowing up a jetliner or two, in others, where a large percentage is
ignoring the reg, it is quite easy (as was the case of snorkles in the
caves) just by comparing the accident rate for the two groups. Which is why
we keep begging the "O2, the invisible killer" crowd here to cite examples
of injuries cause by ignoring the agency rules.
When PADI observed that cave divers were not dying for lack of snorkles,
they modified their rule. I hope the dive industry will be as open minded
as it gains more experience with O2.

It may be, though, Chuck, that you just have me confused with someone else.
I don't recall ever encouraging anyone to disregard any basic safety regs
or procedures. I have, though, questioned many of them, and frequently
bemoaned the fact that, when it comes to writing the standards for the dive
community, the wolves are guarding the sheep.
