The federal "standard" is one of many, and doesn't apply in Mexico, 
British Columbia, or anywhere else outside the US. Gasses use different 
colors in Europe.

Because putting ANY label on any tank is feeding the problem. The only 
things that I need marked on a tank, I mark on the tank. Maybe you know 
what they mean, maybe you don't.

It only matters if you use my tank.

If you do that, you might die.

Go ahead, pick a tank, any tank.

Don't you guys see it? Do you think I'm the only one out there with death 
in an unmarked tank? Didn't you read the original post? Mako Lodge, on 
the Sunshine Coast, in British Columbia, a for-profit, licensed, 
"professional" supplier of gases, rented a tank to an open water, (non 
nitrox trained) diver, with big IANTD band on it that said nitrox, with 
AIR in it! Doesn't that ring any alarm bells in your head? Like, for 
instance, the one that says "If HE does it..."

Don't you think it might be just slightly wiser to be absolutely certain, 
every time? That you might want to use tanks that you KNOW what's in 
them? That it might even be worth going just slightly out of your way to 
find out? There are idiots all around us. Some of them own dive boats, 
and some of them rent and fill tanks.

Or do you think that if I concede your points, and mark MY tanks, that 
the problem goes away?

I don't care what your tanks say, I'm not using them.

All guns are loaded, there is no such thing as an unloaded gun. 

The only people I know who knew that the gun was unloaded are dead.

This is the same thing, in a different package.
All tanks contain mixes that will kill you, given the right circumstances.

So you better treat that gun like it's loaded. I'm not advocating less 
safety, I'm advocating more. I'm advocating that that car roaring up to 
the stop sign on your right is going to ignore it, and you better be 
ready. I'm advocating that the labels mean nothing, (witness my original 
post), you better check for yourself, or you better watch the fill, and 
go to any other lengths you deem neccessary to know what's in that tank.

My original post, with the story about Canadian Nitrox, was posted to 
show that labels are often incorrect, and, as such, mean nothing. The 
prudent, responsible diver, therefore, takes whatever measures are 
neccessary to ensure that gas he breathes at depth is the gas he needs.
