I just wanted to share my thanks for the details, if ever things get too much Ive got my helium tank ready. I've attempted this method and failed once before
300 bar female G 5/8( on the Air side) to 200 bar female G 3/4 on the Nitrogen side.Hi again, maybe stupid question but
I have a 5L 150 bar cylinder with G3/4 inner thread and i need to connect it with SCBA regulator
In that case I need an air-to-nitrogen adapter G3/4" outside thread - 5/8" insed thread 200-200 bar, right?
Oh, I didn't notice that,your G 3/4 valve is female?G3/4 inner thread
Why did you fail? Kind regards.I just wanted to share my thanks for the details, if ever things get too much Ive got my helium tank ready. I've attempted this method and failed once before
Did you have the required purity or was it the party balloon stuff ?I failed twice actually. I tried to hang myself with a ceiling fan and it completely broke off, it's still broken to this day. About the helium I have never really known why it was a failure, I set it up correctly and was expecting to pass out but I just remained completely conscious for at least a few minutes. I remember the feeling of inhaling helium the way things get this weird taste, my head spinning a bit. I think I didn't do it for long enough tbh. It was a very emotional moment I remember.
Aussie? If so the was some new safety standard for non refillable helium tanks need to be mixed with 20% oxygen. I'm going with nitrogen because it seems easier to get and the supplier says it supposed to be >99% nitrogenThat's exactly what I was thinking tbh. It probably wasn't enough helium to kill me because it was from a balloon helium tank which isn't enough. Where can U get helium at that purity (I'm doing good but I always want the cowards way out if all shit goes to hell)
Man thats just cruel
Yep.Can you still put it back together?
There are 300bar SCUBA regulators too.with diving equipment(SCUBA) need 200 bar on both sides because the diving regulator is DIN200(for DIN200 valves).
Carbon dioxide(CO2)carbon monoxide
@Das Nichts did blackout test with plastic bag and said that these small details are not important.Or does it not matter?
So I can just leave the LDV in a bag with the analyser or would that not work?In a well tightened mask you will never have a big seal break, no matter how much do you move. There isn't any realistic situation where that will happen.
Assuming the mask is sealing well then the difference in consumption between NP and PP wouldn't be that much, a PP LDV only maintains a PP over ambient of just 3.9mbar inside the mask, which btw helps with exhalation since this pressure also pushes against the exhalation valve which opens at 4.2mbar.
A big leak in a NP system will simply make the LDV to not open (there won't be enough pressure differential). In fact that's how SCUBA Ambient Breathing Valves work, they intentionally open a leak in the mask to breath air from the external ambient, but this won't happen accidentally anyway. @ertn used an Ambient Breathing Valve to breath air with the mask on before closing it and start breathing the Nitrogen.
That analyzer doesn't have an inlet to pump gas into, so you would have to put it inside a bag a fill it with your gas.
YesDo I still set it for 15lpm?
Rubber hoses are heavy and they're for heavy duty application and not suitable for plastic bags.The hose is about the diameter of my pinky. Is that a problem if I am using the traditional exit bag? If so, what should I do?
There is a source in the ppeh available in the resources sticky thread. Its a nationwide chain deals in tools. Haven't bought mine yet, working up the courage to get it so no idea how tough it is to get or if they are gonna question it.Well that must be the reason I'm alive today then, the helium potency. I will try and get nitrogen but I have no idea where I'd get it from. Maybe just a quick Google?
In combination with a scuba mask, yes. You can also consider SCBA. Try to post some more reactions in for example the forum games. The search function will be unlocked after a certain amount of posts. It makes it easier to search trough this thread.2. wouldn't a scuba regulator serve perfectly well as an alternative to the flow regulators, etc?
Argon is perfectly viable. Few people in this forum have CTB'd with argon, though try to get nitrogen or helium if you can coz argon is a heavier gas which may not work the best wih an exit bag setup1. is argon as suitable as nitrogen?
I don't think this matters. I did it like this:I constructed my exit bag from a turkey cooking bag. Easy to make. Tried it on and with the elastic cord it appears to fit well and is roomy. It does not bunch up near my mouth or nose. The tubing I have is clear flexible plastic. Advice here states to put the tube in so as to be at my back. My question is how far up in the bag should the end be placed? I know I've seen a photo somewhere that had it taped inside the bag with the end up high which would end up being above the top of my head once inflated. Is this correct? Or does it not matter? My concern is nitrogen, oxygen and carbon monoxide have different densities or weight. Want to make sure the nitrogen is at the top and pushing out the oxygen and carbon monoxide. Any advice or a diagram would be helpful.
You could measure you head and try to find smaller bags. In the end I went for a different type of bag with theMy exit oven bag ruffles above the elastic band. There is a possibility of entry of more O2. What are your opinions? Thank you.
if it matters, the linked pdf shows pictures of the deceased. took me by surprise, but it isn't anything too upsettingnot recommended just interesting

very comforting to know butane works in addition to the other gases
PPeH describes the exit bag method and says the following about it:Anyone know how long you're supposed to hyperventilate before?
Which inert gas method are you considering?To minimise the chance of experiencing panic and air hunger, it is recommended that before pulling down the bag, one spends a short time (1-2 mins) hyperventilating (ie. deeply inhaling and exhaling air into the lungs at an increased frequency).
