Dive shop has the air
You want the air
It is up to YOU to comply with what the shop will/will not fill, or convince them that the tank is safe
Make no mistake about it, I feel that it's entirely within their rights to refuse to fill any cylinder. What interests me is "Based on what?" You keep asking to have it proved to you that the cylinders are safe. The DOT has visited this question, revisited this question and revisited this question yet again at last count. The truth just doesn't change. 6351 is a safe cylinder when properly inspected. The key here is "properly inspected". I don't think all shops properly inspect cylinders. So instead of this "self regulating" industry "self regulating" and getting their act together and training their staff properly, they shift the blame somewhere else, and make the customer pay for their ineptitude.
I don't blame Stephen for getting nervous. There are some real tank monkeys out there. Take for instance the guy that pointed out my cylinder had to be O2 clean before he filled it -- with Argon! And I'm supposed to somehow prove to a moron like that that my cylinder is "safe"?
Ignorance and greed are the only two things that are driving this 6351 debacle. The dive shops won't shell out to send their tank monkeys to a PSI class, they do bad inspections and when tanks go "boom" they blame the alloy, not the owner of the LDS that told the 16 year old untrained kid to inspect the cylinder.

That should be easy enough to understand
Is there some reason that the LDS should not trust the DOT since they have, and can supply all the information required to prove that the tank is safe? Since the LDS feels that the cylinders are unsafe, and the experts, the DOT, says that they are, perhaps you could shed some light on what information the LDS has that the DOT is missing?
Otherwise, the LDS isnt an expert (thanks for pointing out that youre not one too) and this is just sensationalized reporting of a few (but tragic, make no mistake about that) accidents averaging about 0.5 deaths/injuries a year. If the shop was REALLY interested in saving lives, theyd get out of the dive business completely, which is responsible for 200 TIMES that rate in deaths per year.
Refusing the fill the cylinders is pure and unadulterated greed. The LDS wont fork out to properly train their employees, they point to their own failures (improperly inspected 6351 cylinders going boom) and blame the alloy, rather than the real problem (their self regulating industry is failing to self regulate) and then have the audacity to really stick it to their customers by selling them another cylinder (which is 10 years who knows they might come up with another fear, rather than logic based reason to stop filling).
Its pretty downright disgusting when you look at whats really happening.
