Method Exit bag and inert gas megathread

[Kapsyl]

This sounds interesting. Has this ever been used before? Liquid nitrogen in a confined space. I wonder how much you would need.

Liquid nitrogen expands 696 times at 20 degree Celsius as it vaporizes. So it depends on what kind of confined space we're talking about

A typical car is about 3000 liters of inner volume for reference.

But a few liters of liquid nitrogen at least, the more the better until the point of ridiculous of course.

I have a sedan-sized car that figures into my plans regardless of the specific method (ie... one could exit bag in the car as well.) It's in a small garage with a closing door for privacy. I liked the idea of the liquid nitrogen because it combines the method of inert gas without having to use any headgear.

Sort of like a DIY sarco in your beloved car. Sounds about perfect.

Edit: I might be worry about some it leaking out though. It seems crazy strong and totally undetectable by any passersby. Might not be very responsible unless you had a totally sealed chamber/very secluded location. Although, the cases of accidental death seemed due to continuous leaks, whereas a few liters would probably dissipate rather quickly. The fact the the car would be enclosed within another enclosure -- the garage -- though not airtight, would likely prevent a large buildup outside. As long as one didn't use much more than one needed.

Liquid nitrogen is not straightforward to obtain, it turns out. And it has to be transported in some kind of special vehicle. Maybe delivery is possible?


Cost wise seems good. The container is what will cost you a couple hundred bucks.

Is liquid nitrogen as easy to obtain?

Sounds very cool, I wouldn't think liquid nitrogen is easy to obtain, if it is I might get some just to mess around with , crazy stuff.
In seriousness though, I'd be weary of doing untried and true methods personally,( I'm weary enough about tried and true methods like exit bag, gun methods etc ) but that's just me . Maybe you could run an exit bag rig in addition to dumping out liquid nitrogen

After some additional research, I found liquid nitrogen is very easily obtained in the US. It's about $4/liter and you need ideally 10 - 15 liters to saturate a small enclosed space. The containers cost $200 - $300+ but can be purchased cheaper used. This hasn't been used by many people to ctb which is why it's still readily available. In terms of reliability and simplicity of setup, it should theoretically score highly. If more people actually try it, we will be more confident, but then it will also go the way of SN and become a legend of the past that no one can access anymore. I guess this is just the inevitable cycle all these methods go through as they get discovered.

At this point, the most ideal thing I can imagine, is rapidly decanting 10 liters liquid nitrogen, into a wide, flat container (like a metal pan or something), in medium-sized weatherproof tent. If you keep your body low to the ground, there's practically no chance you won't be out in seconds flat. It seems more foolproof that the mask/bag avenue, which it seems like people have a propensity to mess up some detail and abandon the method.

Interesting. Im into it.

Interesting. Im into it.

theres another thread on this forum, im trying to find it. Just search for the word "dewar" which is what the containers are called, and you'll find some other threads with this discussion. Another member posted a Youtube video where this guy shows how easy it is to buy.

It's almost kinda morbid, his kids are sticking their heads into the container as it sublimates, no clue how it could have just wiped out that whole family while the dude pours it out in front of them. This stuff has been responsible for large scale peaceful death accidents at several industrial plants.

But it shows just how easily purchased it is for any dumbass. Maybe that is about the change after all this discussion on here... my bad....


I don't know.. personally I think it looks like a beautiful sexy chemical.

Edit:
Fatal Inhalation of Nitrogen in a closed Environment - academic journal paper this guy died in his car. He had 5 small containers, a couple must have leaked.

Never mind, I found 2 sites. Now for that regulator... According to Boudewijn Chabot (Uitweg/Diginified Dying) it's not really necessary.

I would highly recommend a regulator and a flowmeter. The old resources doesn't list them as necessary because they used lower pressure ballon canisters. High pressure cylinders like 130-200 bar isn't as easy to simply open and direct the helium as the previously referred canisters.

I'm maybe old school but I wouldn't trust life altering decisions be dictated by any chatrobot/chatgbt.

Boudewijn Chabot is a Dutch psychiatrist for the elderly who wrote a book 'Uitweg' (translated as 'Dignified dying', 15th edition, revised in 2022). But you're right, he's talking about helium tanks for balloons, so thanks for the tip. I'll keep it in mind.

Oh my bad, i genuinely misread his name for chatbot lol.

Do you know the thread connections on the proposed helium cylinders? If it's common you can still use an argon flowmeter with a conversion chart.

I thought as much.

I have no idea of the thread connections. It's a 50L tank of helium bought and delivered in Belgium.

Look common enough, unfortunately I don't know what thread it is. But the connection doesn't look proprietary for helium use only since such big cylinders are used interchangeably between different gases.

50 liters is quite overkill, like 10 times my recommended amount lol. But I get that they don't sell any lower amount. What's the price? Must cost a fortune since helium is quite expensive even in small amount.

Over 400 euro without tax (+21%). They also rent 10L and 20L, but I think those are 92% helium. The money isn't a problem; I'm more concerned about the weight. (-:

It's 300 bar, but that doesn't really say anything to me. Chabot mentions in his book something like multiply liters with PW value to know how much compressed helium you've got. Site doesn't mention PW unfortunately.

Weight wise a 50L is about 55 kg (120 lbs).
From what Ive read, 50L of Helium is about 10 m3
This is a huge cylinder.

Better to be safe than sorry. (-; But I think you're right: the tank is probably at least 49 kg. 10L or 20L is better.

I also checked the PPeH and it says in Europe they use type DIN 477 regulators.

 

[EsotericByDesign]

After reading the start of this thread, and various posts within, would someone be able to clarify for me what numbers to aim for? I've seen several ranges mentioned. I've found 99.99% pure helium tanks (their label) that list the weight/amount(?) as 19g / 103 Liters compressed / 27 gallons. I'm assuming one tank wouldn't be enough, but would two? Or, likely, probably need more?

I'm considering the EB or SN to CTB method, depending on how much material I can gather. I have questions and concerns about the EB method:

- I found a bottle of nitrogen for sale on a beer brewing equipment website. It's a 2l x 240 bar bottle, or 480l of compressed nitrogen if I'm correct. The bottle is labelled "food-grade nitrogen". Could this have an impact on the success of the EB method?

- Is 480l enough? At 15/min, that's 32 minutes of gas, which is more than the PPHE recommends.

- Is the EB method still reliable? Is there another method like EEBD, SCUBA, SBA or does it require a larger quantity of gas?

Sorry if my english is not good, I'm using Deepl

did you find out what percentage concentration this is? you'd need to know what food grade nitrogen concentration represents.

 

[devils~advocate]

did you find out what percentage concentration this is? you'd need to know what food grade nitrogen concentration represents.

Usually this will be at least %99 or even finer than that. The 'Food Grade' means its been certified, tested or meets standards. I dont know exactly what standards those are, but no matter, as long as its high purity. Actually with any gases I would think as long as you have 95% that should be good.

 

[ReadyToGo34]

Hi everybody, I'm hoping somebody can help me. I ditched my other method and decided upon nitrogen with an exit bag. I'm still nervous about doing everything correctly, but I'm just going to keep researching until I'm confident. The one thing I'm really having a hard time with is the regulator I'm supposed to use. It seems the only ones I can find are for CO2 and/or Argon. And the ones that I find that are made for Nitrogen only have things that tell the PSI and nothing about the Lpm. I keep reading conflicting information about what it should be set at, then. Some things say between 15-20, even if it's intended for other gases. But then I've read other things that say it should be set at 12??? I'm just so confused. I wanna be sure to get the flow rate right, I can't have this fail & end up a vegetable. Any help would be appreciated. Thank you.

 

[heavenplzhelp77]

How would it benefit from using the regular inner mask of the hood? Or are you referring to the exit bag?

I can tell from experience from using a closed constant flow setup that 10/lpm is not nearly enough, even with shallow breath 25/lpm was just enough to feel comfortable 30-35/lpm is what I'm going to use most likely.

Why would less than 25/lpm feel uncomfortable? If I'm using an exit bag with 15 or 10lpm would it still feel uncomfortable and therefore i would have to use the higher flow rate?!

Neither 15 LPM or 25 LPM Nitrogen felt uncomfortable to me, just the opposite

PPH states: 15 lpm when using a self-made exit bag, 25 lpm if you're using a hood (like the 3M Versaflo).

Yes, I plan on using 25 LPM as recommended

 

[Tommen Baratheon]

So you're using a hood like this? They're quite expensive. This one is about 445 euro.

No, I got mine from escMode out of Canada before the authorities shut it down, about $200

I've never seen anything that supported less than 15 lpm for exit bag . Argon regulators are fine , just be mindful of th argon flow—->nitrogen flow conversion 15 lpm argon is like 17-18 lpm nitrogen.

PPH states: 15 lpm when using a self-made exit bag, 25 lpm if you're using a hood (like the 3M Versaflo).

Do you think there's any negatives for higher flow rate like 25-30 lpm for exit bag ? ( assuming ample supply of gas )

 

[Tommen Baratheon]

I have no idea. PPH advises 15 lpm for an exit bag, that's all I know.
