mempilot:Wow! Thanks! I never knew that. :06: We can all learn a lot from you.
dab:Why do people have to get so sarcastic and condesending when they disagree? Understand the issue and make your decision on filling your tanks. No need to get personal.

Ah, yes... that's just the way I read it the first time. Then I got to thinking... (always a dangerous thing)... doesn't air at 200+ ATA constitute a "hazardous material?"The Kraken:And to add:
""The pressure of the hazardous material at 55 °C (131 °F) may not exceed. . ."
. . . the red, bold highlight is mine.

oxyhacker:This has been gone over here many times. The CFR you cite applies, like all the DOT regs, to tanks "entered into commerce", not privately owned tanks. Ditto the osha regs. So it is not illegal for diver - or a dive shop even! - to overfill a tank, or even fill one that is out of hydro.
Anyone who doubts this can pick up the phone, call the DOT, and ask for Hattie Mitchell, chief of Regulatory Review at the Office of Hazardous Materials Standards, and get the straight facts.
I have spoken, BTW, to the Hazmat people you give the link to - they tell me that if I want a definitive opinion I should write Hattie!
You might be surprised to hear, Chris, that I am not an advocate of overfilling! I do, though, believe in giving grownups accurate information, and letting them make up their own minds. If something is dangerous, I would rather explain why it is dangerous, than just tell them it was illegal when it is not.
