Nitrox Tank Marking

[boulderjohn]

Yes, of course, and I do. But I am referring to the millions of new or otherwise recreational divers who rent tanks or dive resort boats? they are not analyzing. They do not own an analyzer and they are not going to ask the dive shop to borrow one, they wouldn't even know how to use it. I don't believe it is necessary for them to analyze.

I am pretty sure I have never, ever, gotten Nitrox from a source that did not have an analyzer on the site for you to use to analyze the tanks you are renting. Many and perhaps most absolutely require you to analyze, write the results on a log sheet, and sign it. I was most recently diving in Palau, where our tanks were provided to us on the boat. As we headed to the dive site, crew members went to each of us with an analyzer and a clipboard where we would personally write the results and sign for them.

Can you tell me where you get your Nitrox that does not do this?

. Also did you realize that the word "analyze" comes from the word "anal eyes"!

No, I didn't. I will think of this every time I analyze my tanks. Thanks.

Well, if you are filling at a reputable fill station and are getting air or basic 32 or 36 nitrox and if there is a tape on the tank telling the fill analysis, date, fillers initials, etc, like it's supposed to then no, it's probably not necessary to re-analyze. At some point you have to trust the dive shop. But if you have the ability to test, then why not? I re-analyze everything.

“At some point you have to trust the dive shop”

That’s some of the worst advice I’ve read on SB

I was in Bali, diving out out of a “reputable” dive shop. We got to the site and they handed me a tank with tape on it sayin “32%”. I asked for the analyser and they said “its back at the shop but it’s fine we have already analysed it for you”. Long story short I refused to dive gas I hadnt analysed and they brought me the analyser. It read 43%... let’s not trust the dive shop.

What's the best way to remove a Nitrox band that is quite stuck on a tank?

Razor.

Wouldn’t a razor scratch the thin galvanized or painted coating, opening the door to rust?

I have a typical razor scraper, the kind used by painters. I can't begin to estimate the number of VIS stickers (etc.) I have scraped off of tanks, both galvanized and painted. I have never left a scratch.

I have never felt the need to take an entire nitrox band off, though.

You are undoubtably rather skilled at it!

There is no need for any particular skill. It's pretty easy.
