OK , so here's question # 1.
Who's LDS is NOT using top quality air?
Question # 2.
Who's gear is THAT dirty?
Now here's where I tell you I brew my own mix, I will use any of my tanks, or any of my gear, to fill or breathe pure O2 at any time.
And NO I'm not a Darwin candidate.

Yes it's welding grade O2.......
Be careful, be clean, and do some learning first. Take it easy on the fill rates, and you're more than half way there to a safe fill with any "marginally clean" gear.
Which is not to say dirty gear is a good thing.
