No wonder Cee Bee despairs.

Stop creeping and get on with it.

Thank heavens we get to vote again...

Since we all seem to be penny less, i suggest that we all stake out our own freeway offramp with a sign " will dive for food/o2/sorb" then maybe we will be able to dive with fresh sorb.

I as a homebuilder probably have no room to talk here but somebody has to say it. There are only two scubapro regs rated for o2 use, the mk20/mk25 with the right seals. Is two hundered dollars worth a trip to the burn ward. If your sorb is out of date,trash it it is not that expensive. You probably spend more on gas going to the site then for fresh sorb. Use breathing grade o2, i am guilty here too. We have no idea what is in those welding o2 cylinders.

i have made some good friends on this group but i don't have the money to go to your funerals, so don't die doing something stupid.

Well there you go see its not that cut and dried.

I am absolutely terrified of a C02 hit so I you would think I would never use out of date sorb. However if I suppose if enough people told me its was no problem Id do it and defiantly if one of those people was someone I had a lot of respect for.

Its like the pre breath thread on here. I didn't know that prebreathing wasn't necessary to get the sorb working but someone like Dave Cooper says its so and i go, "blimey it must be true".

So when respected dive buddies tell me there is bugger all difference between welding 02 and diving grade 02 I believe them. Ill never forget my M8 and fill man laughing and pointing out if there was acetylene contaminate in the 02 bottle it would go bang when you filled it. He went on to say 02 grading was all about batch testing. X amount of batch tests = X grade of 02.

He pointed out that just about all contaminants burn when exposed to pure 02 so he asked exactly what sort of contaminates I thought there was in welding grade? He also dispelled the humidity myth. Damp 02 for medical use. Very funny he said. That will rust the inside of the 02 cylinders nicely.

QED i would happily use welding grade 02 and have done many times. Analyzing the 02 when I get it should show up any cock ups on the fill. I don't think may other 02 users analise the 02 before use.

02 clean regs? Never owned one, haven't had a fire so far. I remember going to get my Oceanic 02 cleaned and they told me id have to buy Oceanic Nitrox regs. Pretty green and yellow ones. I sad screw that then proceeded to breath 80 and 100% out of it for the next few years. My friend and Apex service man pointed out they use 02 grease on everything these days to avoid possible mishaps.

My old Oceanic is still on my deep bailout bottle but i use the TX50 for the shallow rich mix because its a less noisy breath. The TX50 isn't 02 clean either.

I think there is a difference between skinflint and not wanting to be ripped off.

I had an argument with a dive shop once that wouldn't let me analyze an oxygen fill they just gave me. Fine, I told them, dump the gas because I'm not accepting (i.e. paying for) it without checking it. They changed their mind.

Analyzing a "pure" O2 cylinder should be the first thing you do with it. I'm surprised that this isn't a common practice.

Cheers,

Analysing ANY cylinder that's been near a Nitrox bank or O2 should be common practice, even if it is an air cylinder. 7 or 8 years ago, some members of my club were on a Trimix course at a location that I won't disclose. Another student doing a Mod 1 course picked up his non-O2 clean bailout after filling and went diving. When he did a bail out at depth, he toxed. The bailout had been filled with 80% despite being clearly marked for air.

It's only down to fast reactions on the part of the instructor, the good first aid training the members of my club on the boat had and luck that the chap walked away alive.

Not a nice thing to happen to you....

I must admit, I became a little complacent about this for a while, then witnessed a real money totally screw up my O2 fill using his 'brand new' panel. That was all the reality check i needed.

Mikes at Chiswick, London analyse both my O2 and dil cylinders in front of me, the fills book is filled out and signed.

It's down to the individual diver or LDS staff to insist betwen them that this is done.
