A diving cylinder (the term which tends to be used by divers) or SCUBA tank (more often used colloquially by non-divers)

As a NOWI Certified Diver and a PADI Certified Diver for more than twenty-five years, I can attest to the fact that I have never heard an American diver or American Oceanographer refer to our "Dive Tanks" as anything other than "Tanks." Therefore, the author's statment as prefaced above in parenthesis may be not be valid.

In any case, the reference to "non-divers" seems a bit unnecessary and sounds more like personal opinion rather than an actual fact. I recently, reviewed my old dive manuals whereby, the official terminology used here in the USA is "Tank" and not "Cylinder." The only exception I found was at a PADI web site tonight. However, I noticed the date of birth on the registration page of the website is European I.e. day/month/year as opposed to American month/day/year. Therefore,the term cylinder would be more appropriate coming from European divers. There is also a dive master video on the NOWI website regarding equipment. The term tank is being frequently used by the dive master when referring to the breathing unit.

I have seen the same (idiotic) argumnet over the term skeg or fin on a surfboard and have heard some say that only a non-surfer would say skeg. I simply believe this type of commentary detracts from the article in general and is therefore, may not necessary.

PEACE (LCrockett 04:16, 15 December 2006 (UTC))hope I did this correctly :-(?

You don't have to indent paragraphs (screws things up if you do). Otherwise you did fine.

I get three times as many Google hits on scuba tank as scuba cylinder. But I do notice that makers and engineers tend to call them cylinders. Perhaps this filters down to those who want to sound like the people who make (and service and hydrotest) the stuff, rather than just use it. SBHarris 08:23, 15 December 2006 (UTC)

Should Diving tank be added as a redirect to this article? --ArmadilloFromHellGateBridge 08:36, 15 December 2006 (UTC)

Yes, I think so, and have done so. Along the way I fixed the definitions so that I think everyone will be happy and satisfied. "Gas cylinder" is the generic term used by engineers and the ACGA people who use all kinds of sizes of compressed gas containers, not just the ones for scuba. Even the big H cylinders get called tanks by the non-cognoscenti, but never by people who work on them for a living. The same kind of distinction carries over to scuba.

[edit] Diving Oxygen

"Breathing industrial compressed gases can be lethal because the high pressure increases the effect of any impurities in them.". I breath welding oxygen on a regular basis and so do a lot of other people. My research says it's the same oxygen used for both applications. Maybe that should be clarified. 142.165.246.187 16:13, 10 February 2007 (UTC)

I would wish to take issue that welding and breathing oxygen can be regarded as the same product. In the UK, USA and Europe there are both civilian and military specifications for welding oxygen and for diving quality oxygen (and medical oxygen). I would suggest that you could safely use diving oxygen and medical oxygen, if you wished, for welding but it would not be sensible to do so as these products are more expensive than welding oxygen. Likewise, you could use industrial grade oxygen (welding oxygen) for diving, however it is not sold (in the UK and Europe) as a breathing gas; and that it would be safer to use one that is sold for that purpose. Perhaps, that partially answers your point.Pyrotec 18:29, 10 February 2007 (UTC)
