Ouch, we already beat this horse to death on rec.scuba.

To Raimo I repeat, I respect a shops right to be wary
of strange tanks.  My nitrox tanks get their fills only from Nitrox shops
or they sit empty, the shops I use know this, they know I hate breaking
my doubles up to clean them :-) (and the neighbors downstairs can't enjoy
the rolling much either) , so I can get 21% fills when I want.  I would 
hope that no matter where I moved I would be able to establish that 
kind of a relationship with the local shop I most often used.

Not in the interest of discarding safety standards, I would like
to see more responses to Ken's question of a few days ago.  In 5-6
years now on the net, reading techdiver for the past (3-4? when did
it start) years, rec.scuba, and then cavers, I have never heard of
an oxygen accident at a shop.  I have heard of people having
homebrew accidents.  I repeat this question mostly for
my own curiosity.  

I have two standards of safety, a very high one for others (I do what 
I can not to put others at risk) and a lower one for myself (ie I'd 
try X, I think its safe enough, but I wouldn't bet someone else's 
life on it.)  

As for the "you gotta slap a big honking sticker on it" crowd I challenge
you to re-read Jammer's story.  All the Nitrox-marked tanks had 21% mix
in them (some call it air).  Some people will say this was mis-use of
the stickers, well ok, fine, what if those tanks had had 22% in them?
Would be a lot harder to call it a mis-use then, but the effect would
have been the same.

All the unmarked tanks had 36% in them.  Had Jammer's tanks been
marked with Nitrox stickers how would that have helped in ***this***
situation?  NOT AT ALL.  

My own standard is that I mark my (nitrox) tanks in other ways so noone
will mistake them for theirs.  Their should thus be no confusion
about the gas in my tanks.  Its irrelevant. (to anyone but my buddy) 
You aren't the one who should be breathing it (and the buddy is
well informed ahead of time).

Mike
