Method Exit bag and inert gas megathread

[sm1the]

Considering that nitrogen is slightly lighter than air, at a flow rate of 15l/m I would say that any O2 is pushed out of the hood/bag pretty quickly, maybe just a few seconds.... Also the hood is pre-filled with nitrogen before you pull it down to the head. Maybe do a test but this time you pre-fill the hood/bag beforehand? Sorry this is all I can help with. I hope your health sitation improves.

Hood needs to have a normal O2% (20.9%) before testing starts.
We are testing-
1- time it takes from when 25lpm is started(gas turned on) to 0% O2.
2-Then,testing how long it can hold a very low(under 5%) O2 environment AFTER gas is turned off.(I'm not too sure if many ppl do this,but I saw 1 or 2 did so I added this part of the test.).

Thanks for trying to help,I do appreciate it.

Exit Bag and Inert Gas Basics —A very, very long post, I know, but I feel like I've fielded a lot of questions about this, so I figured I'd spell out everything I know. Others on the forum should please add to this thread whatever reliable technical information they feel is appropriate for someone attempting this method to have.

The idea behind using an exit bag with inert gas is to create an atmosphere around your head that is both free of life-sustaining O2 and can carry away the exhaled CO2 that would activate your hypercapnic alarm.

The Gas:

You will need to keep the inert gas flowing at 15 liters per minute (Lpm) for 40 minutes to be confident of ending your life —in other words, you'll need a minimum of 600 liters of inert gas. In the past this would have been helium (He), but due to the uncertain availability of genuinely pure He, the best current options are nitrogen (N2) and argon (Ar). Both are reliably available in pure form (no air contamination) from stores that supply welders. N2 is also available from some brewery supply houses, but the purity of the gas should be confirmed to your satisfaction. Both N2 and Ar should work to ctb and are similar enough in their properties to be treated identically for use with an exit bag.

Pressurized gas cylinder sizes are not standardized across the industry, nor internationally, and it can be difficult, if not impossible, to tell how much gas they contain from a photograph on a website.

In the US, a 20 cubic foot (cf) cylinder is the smallest you should use for ctb; a 40cf will allow some margin for flinching, practicing, etc. "A 20cf" and "a 40cf", or "a 20" and "a 40" is nomenclature US welding supply houses will recognize, so asking for either should get you the desired product. A 20cf cylinder is quite small for industrial use; I've had clerks tell me, "well, we have a 40, but we'll need to special order a 20." It's up to you what you do in that situation. Personally, I have a 40cf cylinder. It has allowed me to flinch and abort my attempt three times now, and I don't need to worry about refilling it. I bought my N2 at AirGas, a national company here in the US. They do not demand any sort of professional certification for purchasing inert gas, and no more than the usual forms of ID depending on payment method.

I know nothing of gas cylinders outside the US, so if you are using other than US-typical cylinders, you'll need to call and ask to make sure whatever tank you're contemplating holds 600L of compressed gas. Hopefully knowledgeable forum members will add cylinder sizing information to this knowledge base.

Cover story: N2 and Ar are both used for welding. N2 is used in beer brewing. In my day job, I use both N2 and Ar to flood partial cans of expensive paint, to displace the O2 in the cans and prevent the paint from skinning over and going bad. It's a cost saving measure. The clerks I've bought gas from have never heard of that trick, which has meant they don't know enough to interrogate me on my motives or to try and quiz me on my welding knowledge. They have merely said, "huh! That's a new one!"

The store clerk may ask how you're carrying the pressurized cylinder "back to your shop," since pressurized cylinders can be very hazardous to transport (the valve is vulnerable to damage in an accident). I haven't had any trouble when I have told the clerk, "in the back footwell of my car, and very carefully padded!" What they really want to know is that you are aware that a pressurized cylinder is a missile waiting to explode if anything damages it, and that you know enough to not let that happen.

Hey thankyou for this but I am in need of your help please can u respond, I need help am stuck so badly , I dont know what to do , I have so many issues and questions

 

[h4ppyhypoxia]

hello, after an attempt to CTB last month my family is on high alert, meaning im not able to act atm, when i move out late next month, ill be proceeding with my plan, however ill be living in student accommodation, so i cant order N2 directly to my building as its a prohibited item, due to this, ill have to order it to a local pick up point

my problem is that the only nitrogen bottles ive seen on ebay are 2L (28 mins gas flow) or 8L (82 minutes) the 8L bottle i found comes with a regulator and tubing, but the only issue is that it weighs 15kg and is 82cm, so id have trouble transporting it, ive not got a car, so id have to get an uber from the pick up point, and carry it up some stairs to get to my room, would you recommend attempting to carry the 15kg bottle (im around 41kg) or just attempting to CTB with the 2L bottle? im not able to order gas directly from the supplier as i have no car and I doubt they would hand it over if i told them i was transporting it in an uber, also the 8L bottle is 82cm so the driver might have some questions but i could fit the 2L bottle in my bag safely

was thinking of ordering 2 bottles of the 2L nitrogen bottles and only setting off the second tank right before i put the eb over my head, but im concerned that will produce a surplus of gas and that the bag could potentially blow off my head

basically, what would you do in my situation? how risky is it to deviate from the recommended 40 mins of gas flow? saw exit say 2L of gas is suitable but after coming on here im not so sure

 

[pillowpet13]

I was looking to buy this regulator to go with my N2 cylinder but had some questions.

https://www.amazon.com/gp/product/B07TFT9P23/ref=ewc_pr_img_2?smid=A2KS7K4G96NBBA&psc=1

Am I able to attach tubing directly to the regulator above? Also would someone be able to help me figure out the size of the tubing required? Or if they have any other recommendations of what regulator to buy it would be greatly appreciated!

As Exit says 2L is suitable. 5L is the ideal, even though you do not need 5L. If the setup is properly done the brain is gone in 5-10 minutes. With a 2L cylinder you do not have room for testing, so you can buy two of them (one for testing). If you are not confident with 2L buy the 8L.

That regulator should do you fine. You are able to attach tubing directly to the regulator. "Oxygen hose/tubing" is used for this which you can find on amazon.
Look at the thread below, you got many setups and you can see the photos for your reference. I assume that you are going for exit bag, you got many examples there.

yeah thanks i am going for an eb, id go with the 8L to be safe and have some test runs, but unfortunately its going to be too heavy for me to carry, and im not sure how to get around that, any ideas?

as for test runs would you recommend buying a dummy head to practice on or should I practice on myself? ive attempted to ctb with a helium setup before but it was pretty naff and failed but i almost blacked out which gave me more confidence as i also learnt that this method is as painless as its rumoured to be

 

[lunamoonki]

The helium tank I purchased came with this type of valve:



Can I use this to achieve loss of consciousness? That's all I need. I plan on CTB by FSH. The helium is just used to knock me unconscious so I don't feel the hanging.

Would I just turn the valve on like 1-2 rotations to release the gas into the exit bag and keep it running so I stay unconscious?

 

[User8]

as for test runs would you recommend buying a dummy head to practice on or should I practice on myself?

I dont have a dummy head and I have not done many tests with my setup, I am very confident I got everything right, I chose the SCBA method. But maybe you could get one and test. If you practice with yourself it's very risky because you can go unconscious in as little as three breaths, or 10-20 seconds. At that point there is no going back unless someone pulls the bag/mask off your face, so be very careful. Are you going for EEDB or Exit bag?

 

[h4ppyhypoxia]

going for exit bag and yep it is risky to practice on yourself when i said that i mean filling the bag with a little nitrogen before you pull it over your head just to double check the seal on my eb is right and it will work when i go the full way (not actually pulling the bag down over my head)

just want to be as confident as possible because im most likely going to have to go with the 2L cylinder for my eb, are there any other things you'd recommend for me to do to be close to certain it would work?

You are saying 2L = 2 liters right? I thought people were recommending much much higher quality than that. Something like 15 lpm so that would mean like at least 300L of helium. Is 2L going to be enough?

im using nitrogen, most feasible canister for me is 2L at 200 bar, which gives 400L, ~27 minutes of gas flow, but im just wondering how risky that is as exit says it would be enough but people here recommend having 600L which is 40 mins gas flow, the canister which exceeds that amount is far too heavy for me to carry

 

[User8]

The best balance is a 5L cylinder at 200bar. It gives more peace of mind. Most people go with 5L or 10L. The 2L has also been widely used.

2L Cylinder
The 2-liter cylinder at 200 bar contains approximately 400 liters of nitrogen at atmospheric pressure (1 bar).
Calculation at a flow rate of 15 liters/minute:

• Theoretical time: 400 liters ÷ 15 L/min = 26.7 minutes

More realistic data:
In practice, you will not be able to use all the gas because when the cylinder pressure drops too low (normally below 10–20 bar), the flow becomes unstable or stops.
Approximate actual time:

• About 24 to 26 minutes safely at 15 L/min.

5L Cylinder
Time at 15 liters per minute
Theoretical time: 66.7 minutes
Approximate actual time: 60–65 minutes

Thank you so much for your help! Yes I'm currently in the process of building my exit bag. One last question, does it seem like 1/4" oxygen tubing is the right fit for the regulator above? This is my first time buying this kind of stuff and really don't want to mess it up, thanks again!

Hi. Can you tell me if this is equivalent? I am so confused as far as the liters goes.

High Purity Helium Tank 99.99% (19g / 106 liters)

Helium Tank High Purity 99.99% Pure Made in Italy Our high purity helium tank arrives filled with 103 liters of compressed helium gas. The gas can be removed using our regulator or valve dispenser that attaches to the top of the tank. This tank will produce a continuous ~31.5 Seconds of helium...

This one I got is 106 liters which is significantly larger than 5 liters you are suggesting.

And the valve that I got with the tank, do I just turn it very low? Like 1-2 rotations?

Besides that, 200 bar is high enough for making nitrogen expanding about 1.05 times worse than ideal gas, which means getting about 380 liters instead of 400 liters at the sea level, assuming that the temperature doesn't change after expansion.

 

[User8]

does it seem like 1/4" oxygen tubing is the right fit for the regulator above?

I am not sure mate. You gonna have to try. I am not proficient about exit bag but it looks like other people in this forum have been using regular oxygen tubing.

This one I got is 106 liters which is significantly larger than 5 liters you are suggesting.

And the valve that I got with the tank, do I just turn it very low? Like 1-2 rotations?

5L cylinder compressed at 200bar = 1000 liters of gas.
Your cylinder looks tiny and the valve is nothing I have seen before. You probably better buy a pure nitrogen cylinder at a welding store and then connect a gas flow meter regulator so that you know that you are pumping 15L/m into the bag.

All of this tank stuff is confusing to me. Yeah the tank I got is pretty small but I hope it's enough to achieve loss of consciousness. That's all I am really after. Hanging is what I am really using to go. The helium is just needed to make me unconscious.

I agree with Shewaitsforme: you would have a difficult time reducing the available O2 in such a large, gas-permeable space. Technically yes, you could do it, but it would take a lot of N2 and careful preparation of the car.

Don't confuse inert gas asphyxiation (IGA) with CO poisoning. They work through completely different mechanisms.

With IGA you are displacing O2 from your environment, thus depriving your body of necessary O2, while flushing away the CO2 that would trigger your body's hypercapnic alarm and cause involuntary self-preservation. To effectively displace the O2, you need a controlled environment from which the O2 can first be flushed and then excluded. So first you need to get rid of all the air, then you need to keep out any further air, then you need to flush away your exhaled CO2. The smaller the space, and the more readily the space is sealed, the easier this is to accomplish.

When you put an exit bag over your head, you are creating a low-O2 environment. The CO2 is flushed away by the constant flow of inert gas, preventing alarm, and you are allowing your body to use up whatever O2 it has in its bloodstream while not providing it any more.

Short version: The O2 in your body runs out and isn't replaced.

With CO poisoning, you aren't displacing air/O2 from the environment; you are introducing into the environment a molecule (CO) which binds more readily to your blood than O2 does. You're providing your haemoglobin with an easier alternative than O2; your body grabs the CO and ignores the O2. Since your blood can only carry so many gas molecules at a time, with the CO taking up all the room in your bloodstream your body is starved of O2.

When you climb into your car with a barbecue that's putting out CO, there's still plenty of O2 in the car's environment. You're not excluding the O2 as you need to do with IGA --replacing the air with a completely different gas-- you're adding to the existing air a new substance (CO) that your body prefers to O2. This preferential-molecule process makes it much simpler to manage the environment on a large scale. You don't need to get rid of the O2, you just need to provide enough CO to take up all the space for O2 in your bloodstream.

Short version: The O2 available to your body is ignored in favor of CO.

would it be unwise to combine this method with SN for maximum certainty of death? lets say i were to ingest SN right before proceeding with my EB, that way if anything goes wrong and im left brain damaged, the SN would finish the job

He is no longer here.
When I picked my n2 regulator , I made sure to pick a decent brand name one and stayed away from any big no name online ones-these are completely unreliable!.
I also decided I will test it by running it continuously for 30 minutes.
I picked a dual stage with integrated flowmeter regulator with a mid brand name.
I wanted a better brand but there weren't any in dual stage n2 with flowmeter integrated.
I did the above especially because I'm not an expert on regulators etc.

 

[sm1the]

I'm struggling to find any more relevant info on EEDB/N2.
I have I have read -
Relevant parts of this thread,
N2 sections in most books.
Other posts on SaSu

Obviously I can't be sure I didn't miss anything
Has anyone else hit a wall in terms of info?.
I would say I put in a medium effort into research and prep.(I'm pretty sick so medium is what I could manage).
I want to do a bit more research and in the hopes it will boost my confidence in the method, unfortunately I don't
know what to read etc.
I did 2 dummy tests with 3 different o2 testers(made a mistake on the 2nd).
I'm currently waiting on a new o2 tester that's better for low o2 testing(most commonaffordable ones are optimized for room O2 levels although they will test much lower amounts)

 

[h4ppyhypoxia]

was wondering if anyone has any info about success stories with this method, and also stories of failure + what went wrong, going to be ctb with an n2 eb late september/early october and need it to go right so i dont end up brain damaged and worse off

i would download this before they delete it.

can't believe noone sees how google owning youtube and android and many other things is not horrible. google is evil and censoring monsters . just that example they google / youtube deleted all how to suicide methods and info like betty making the exit bag.

youtube has a monopoly on all videos. just like google has a monopoly on all websites and information on the internet.

other sites like this one Vimeo have a very few limited videos. but even here there are some suicide methods unlike censored youtube.

when i get time i might download it too but pressed for time and i have the video downloader on another browser.

i'm sick of the censorship too .

we and i see the censorship regarding suicide. but what people on this site don't know is that everything is censored. we see the censorship for suicide because we know that is censored and all the lies like that " everyone wanting suicide is mentally ill" . we know that is a lie. what people on this site fail to realize is that if they censor suicide related topics to this level why wouldn't they censor other or many things? imo they do all of it or most of it . it's all lies. another example " life is good" " death is bad" we see this all the time but imo it's a lie.

does this chi exit bag method work?

id assume so i havent been able to try and make a bag yet im only going to be able to get supplies at the end of september its just very fast paced for a complete noob at this type of stuff so i was wondering if the betty vid was a bit slower / simpler

 

[h4ppyhypoxia]

unfortunately only going to be able to go about putting stuff together for this next month, but what have you guys done to test your exit bags / inert gas setups?
