POLL, Nitrox tank use and analyze

[Randy43068]

The only thing marking my nitrox tanks is a strip of duct tape listing MOD, date, percentage.

In this thread I earlier stated that I'd never seen EAN in unmarked tanks and I would consider it criminally irresponsible to do so. Well this weekend I went diving with an operator with whom I've dived many times over the last 10 years and I was surprised to see the attached. 39% in unmarked tanks except for a strip of crepe tape and I observed that the divers using the tanks were often coming back from the dives with the tape missing and over half a tank of pressure remaining. So even after the dilution from topping off the tanks with air, the next unsuspecting (air) diver will be getting a hot fill. When I complained about the lack of tank markings it was shrugged off with the answer that they rarely do any deep dives so it wasn't an issue.

I always analyze tanks before leaving the shop. I'm not a fan of "trust-me" dives. We normally hear about those in the accidents thread.

I'll go with if your gonna mark your tanks .. at least use something that doesn't peal off during the dive :huh:

The shop where I get my fills analyzes it right in front of me so I know what I'm getting. I never do it myself.

i recently did a dive without testing my tanks. the first day i tested my tank with my cheapo. it was +/- .2 from the tank tag. the fillers fills a dozen tanks at once. so when the others in the group tested thiers i accepted thier test as my own as it was the same batch of air in both tanks. totally smart , of course not. nothing is totally. statisticly probable that my gas is ok yes.
