<div dir="ltr">Hi Steve,<div><br></div><div>I've had the same experience as Hank. You buy a tank, but each time you refill it you turn it in and are given a different one. I really don't see this as a problem, in fact I like it because the gas company takes care of tank inspections and maintenance. If you wanted extra security, I would suggest checking the contents of each tank with a gas analyzer rather than trying to always use the same tank. It really doesn't matter which tank it is, just what's inside.</div><div><br></div><div>Best,</div><div>Alec</div></div><div class="gmail_extra"><br><div class="gmail_quote">On Wed, Jan 3, 2018 at 1:10 PM, Steve McQueen via Personal_Submersibles <span dir="ltr"><<a href="mailto:personal_submersibles@psubs.org" target="_blank">personal_submersibles@psubs.org</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">I tried to search the archives but it wasn't very friendly.

I wanted to double ck. my O2 strategy. After some investigation it seems I will buy a new steel high pressure oxygen tank for external mounting. My plan is to have it refilled with "commercial grade" O2 vs. medical grade 02. As long as I keep my "personal" tank and not allow the filler to swap tanks I should create a "chain of custody" that will help me feel good about not having contamination.<br>
<br>
I am wondering how others are managing.<br>
<br>
Thanks,<br>
Steve<br>
