Long term stored oxygen in Ali80 still safe to use?

Hi Eric,

At least some degree of caution is warranted, especially if you are dealing with a steel cylinder. I had previously heard stories of this nature and always wondered if they were apocryphal, but then this (see below) got submitted, and we published it just a three months ago:

View attachment 831312 Unfortunately I can't share the entire paper with you because it is under a one-year embargo for members of SPUMS or EUBS, but in December it will be released on PubMed Central. However, I will invoke editor's privilege and show you a photo of one of the cylinders (because it is an important educational / safety point!!!).

The one from the other case did not look so bad.

Wow. Truly looks like a worst-case scenario! My tank was aluminum, so fortunately I had no such problems.
