Bail Out Gas

Rickoz · 19th April 2007, 07:05

Hi all.
Thought this might be the best place to post this question.
I have 3 BAIL OUT BOTTLES of for when the sh!t hits the fan:
I have 1x 11L ally of 02, 1x 11L ally of 50%, 1x 7L steelie of trimix gas.
All were fill back in dec 2004 yep 2004

by my LDS (very clean fill station)
Was going to use the 50% as a deco on a OC

dive to 40 odd msw
(a) does the gas go off ?
(b) toxic, Dump It Now ?
(c) Don't be a girlyman suck it dry

This was not filled by a backyarder but a Very Clean Fill Station.

Gas doesnt go off.

Mate, there is no way any of that gas is going to be any good. I will come around and take it off your hands free of charge

Thats what i thought
but a mate got SICK during a dive using a tank stored for some time, no way as long as mine
but he does fill his own tanks with his little oil burner compressor

I would say there were other causes to his problem.
Letting a tank stand will settle out particulate and condensing contamination.
It won't get to become good but it might get fractionally better.
I cannot see a formula for it getting worse.

The only gas that 'goes off' is over pressurised acetylene.
Use enough pressure and it is a high explosive, detonating on a shock wave without needing an oxidant.
That's why I have 'spark' (ie shock) arrestors on my welding gear.

Maybe worth analyzing once in a while, especially the Trimix cylinder, to confirm contents are what you think they are...

Thanks all for the info guys,

jptaylor9 - yep analyzed the old 50% last night sill 50% as it should be & tasted like it was only filled yesterday

The 7L mixed stuff will be tested when required,
this should be done without saying though.

once again guys ta!
