Method Exit bag and inert gas megathread

[gettingkindatired]

I've been studying the nitrogen method a bit, but it doesn't seem to be all that swift and pleasant for me.

I have tried out this experiment several times. I filled a big plastic bag with nitrogen. Then I started to inhale from the bag and exhale into the open air. I assumed this would cause a similar experience to a real attempt, without any risks of injury. After 60 seconds or so this was getting really unpleasant, but I didn't feel like I was losing conciousness.
(For comparison, I can draw a deep breath of air and hold it for 90 seconds with less distress.)

Any idea why I react in this way?
- I suppose some oxygen will seep into the bag and my lungs when I breathe, but it shouldn't be enough to keep me concious for this long.
- I don't believe my nitrogen is contaminated by carbon dioxide or anything else. I have bought two bottles from different suppliers, so getting deficient products twice would be very unlikely. And even if it was contaminated, my negative reaction should be instant, not a gradual increase.

You don't exhale into the open air, you exhale into the bag, that bag must be completely over your head, and get an oximeter to watch your Oxygen levels(ten second delay on actual readings don't forget)--An EEBD hood is more reliable, after just 5 breaths my Oxygen level dropped to 40(but took the hood off at 77)at 25 LPM

Thanks, but you must have misread. I wrote that I wanted to create an experience similar to an attempt, without risk of injury. Practice sessions with hood/bag pulled down and gas flowing would be too unsafe for my taste.

But how did you feel physically and mentally during your trial, if I may ask?

I didn't misread anything, you complained about the Nitrogen method, yet you did a faulty test that means nothing--Of course what I did was unsafe, but don't make ill informed remarks about the effectiveness of the foolproof Nitrogen method by doing a test that is, frankly, ridiculous
I felt fine both physically and mentally even when the Oximeter dropped to 40(supposedly you don't pass out til your Oxygen drops to 25)--Das_Nichts passed out doing the test, only saved because he fell down, dislodging the tubing--He stated that he peacefully went unconscious

 

[HouseofMortok]

The moment you took a breath from that bag it was diluted with oxygen.

A note of caution: just want to remind folks that seriously lethal methods are not to be played with and can't really be "tested" to "see what it's like" without risking accidentally dying. My best suggestion is to read real accounts of witnessed hypoxia w inert gasses, follow the well established protocol without attempting to improve on it, practice by doing dry runs without the gas on, and if/when ready, turn the gas on. Can you still fail? Sure. But your chances for success are a lot better if you replicate the tried and true and don't mess with it. Inert gasses in particular are hailed for being super quick (~minute to LOC, 10-30 for death) and almost as peaceful as N. The pain in the ass with the method is how complicated it is to set up (well, expensive too). This is why there's so much discussion about tiny details. A zero oxygen environment will kill you, period. But trying to experience it without actually dying is super risky and could even be called a fool's errand. PPEH is an excellent resource for the curious.

I don't really see the problems with my testing method. Could you explain?
If I fill a bag with nitrogen and pinch it closed with my hand, its atmosphere should be close to 100% N2. As I put it to my mouth and release the grip some oxygen may seep in, as I stated, but it should not be very much. On the other hand, no remaining O2 or CO2 from my lungs will enter the bag it if I exhale into the surrounding air. (I wore a clip on my nose to prevent any air entering the lungs through that route.)

 

[Jdieiejdjaow]

Today I confirmed my hose needs to be 5/16". I made the order. Should the hose just slide relatively easy on the flow meter barb? It fits but it feels just too easy and I fear once I turn on the N2 at 25lpm that the hose will come right off. Is this a valid concern? Should I buy a hose clamp?

Hose clamp for added measure.

When you can, please post a photo of your final setup.
For others, it would be great to post an item list of all the parts used (length, diameter, sizes, etc)

Thanks. The only downside is that the hose is 25m in length (80 or something feet). They didn't have smaller lengths. I'll have to cut it. Thankfully I got a rubber hose cutter that I bought specifically for this. it works.

I'll post a photo and list of parts when the day comes to transition and I'm in the hotel.

 

[Argonus]

I have finally acquired SCBA mask setup. Now waiting for the cylinder adapter to arrive to hook the mask on argon cylinder. I feel this is the way I trust more than doing with the EEBD hood. (Hand holding the mask was erased from picture with AI edit)

I agree re clamp. My experience is that it should be a bit of a struggle to get it on, and you shouldn't be able to pull it off easily. They say you can use warm water or a hairdryer on the end of hose to help get it on. Mine is actually so tight I couldn't get it off when I wanted to swap to hose from the stinky vinyl one to the silicone one I gave up. Stinky has been off gassing now for about 5 weeks, it's mostly gone.

 

[Setmefree76]

Thank you for this. Last night i was literally watching YouTube vids and contemplating making a bag. PPH mentions sleeping pills and alcohol to put you out. You'll just go while sleeping. It's very appealing.

This will be my choice

 

[KiloCharlieBravo]

I understand its better to be seated than to be lying down. Would sitting in a car (with an exit bag) with the seat belt on not be an option? The cylinder could be next to me (possibly strapped into the seat next to me)? Has anyone heard of someone trying this?

I am seriously considering this. I am often alone in my house for weeks at a time... There is no risk of someone walking in and stopping me.

This thread is very long, I have read the first few pages but not the entire thread. This method seems so peaceful and easy... besides the start up cost, why is this method not more popular? Setting up a hose and regulator is really not difficult..

Hello. I was going to do the same thing with the car, but not in the house since it would make the house value go down from what I read from other people and I want my children to have more money as the move on. Everything I have read is that the best position in to be seated with the tank restrained so that it does not fall over once the body starts to move once you have passed out.
I will also be using zip ties for my hands, one hand zip tied to the chair and the other zip tied to the other hand. It is very easy.
I tested the bag and the tank and within 40 seconds, my oxygen levels fell to 47%. I am confident that this will work for me.

Some people cannot afford the cost of everything while others don't have the dexterity to make sure everything is connected properly.

I hope to be gone soon. I can't stand myself any longer.

 

[HouseofMortok]

Right. It is a good job I double checked..

It would seem the same company selling Argon and Nitrogen, if you buy a kit (with regulator) Then the Nitrogen kit comes with a regulator (no LPM though) that from researching suggests it's 24.32x1/14 connection

It's a good job I didn't buy the Argon regulator (with LPM) as that suggests it's 21.8x1/14

What do I do? I can't find an N bottle with the connection for Argon/LPM flow rate style regulators.

There is only 1 thing I can find, I find it expensive however at £40 for abit of metal.. from Germany, not many sellers, is a reducter
24.32x1/14 to 21.8x1/14, I assume this will work.

I couldn't begin to work out the scba DIN300 stuff with this 24.32x1/14 fitting, so it's just going to be the bag option, but I am abit stumped at using Argon flow on Nitrogen tank, connection wise.

There's no clear picture of the tanks connection/threads.

I guess then, do I buy the bottle first then come back with questions? Or hopefully I've provided enough info to solve this puzzle now?

Thanks.

 

[SomeRandomThing]

600 litres?!
The big tanks here in England are 50 litres and that's approx £150 :(

I'd need 12 big bottles??

 

[SomeRandomThing]

Oh wait... I think that's just the tank water capacity.

• Water Capacity - 10 Litres
• Approx. Height - 910mm
• Approx. Diameter - 140mm
• Approx. Gross Weight - 20kg
• Approx. Nominal Contents - 1.9m3
• Approx. Fill Pressure 200bar - 2900psi
• Outlet Valve - BS No.3 5/8" BSP RH INT Valve

I don't pretend to understand for a moment how to convert this, but careful wording to ChatGPT seems to suggest that it's around 1900 litres, so hopefully I'm good!

It's hard for us to guess how much air you could capture along with the useful asphyxiant gas without knowing the exact technique of breathing you used. I presume, inhaling from a bag like that may be somewhat difficult to do properly. I and other folks who experimented with inhaling nitrous oxide were using latex balloons which worked pretty good for testing, and this method should be suitable for inert gases like nitrogen as well. In order to achieve quick onset, as much air should be exhaled from the lungs as possible prior to inhaling the asphyxiant gas.

I have tried out this experiment several times. I filled a big plastic bag with nitrogen. Then I started to inhale from the bag and exhale into the open air. I assumed this would cause a similar experience to a real attempt, without any risks of injury. After 60 seconds or so this was getting really unpleasant, but I didn't feel like I was losing conciousness.
(For comparison, I can draw a deep breath of air and hold it for 90 seconds with less distress.)

Any idea why I react in this way?
- I suppose some oxygen will seep into the bag and my lungs when I breathe, but it shouldn't be enough to keep me concious for this long.
- I don't believe my nitrogen is contaminated by carbon dioxide or anything else. I have bought two bottles from different suppliers, so getting deficient products twice would be very unlikely. And even if it was contaminated, my negative reaction should be instant, not a gradual increase.

Gettingkindatired , did you read from the beginning of Tired Horses thread (this thread)? It sounds to me like you did not . This is why I hate "megathreads". Newer members start reading at some point way down from the beginning and see where other newer members are spreading misinfo but because it's in a megathread it must be accurate . There is a reason the exit bag is designed the way it is. Did you make it the way it is shown or did you just use a plastic bag that fits your head? This is the kind of situation that validates the people who are trying to shut down SS. I am not trying to be critical of you . I saw a reply on another thread recently someone saying just go buy a CO cylinder. Maybe you can I'm not sure . From what I've seen it's primarily available for research / calibration. Anyone walking into an Airgas and asking for CO would immediately be asked what are you using it for and why the hell would you want it !? It would instantly bring suspicion on you whereas getting regular old nitrogen or argon would not . This is my theory of course because I haven't tried it but it would certainly jump out at me as odd . Too many newer people join and are looking for a quick and easy way out and this is what leads to bad experiences. I've also seen newer members saying to run a hose from the tailpipe into your car and totally not understanding what a damned catalytic converter is. This one should absolutely be added to the very top of the non-methods sticky.

Yes you totally nailed it ! Especially dangerous if you think you can skip constructing parts of the set up . You could end up brain damaged and then unable to follow through later on your own .

 

[Intoxicated]

Some of us are ready to accept the risks associated with testing how gas asphyxiation works. It's up to individual to decide whether the knowledge obtained in such a way is worth risking or not.

Hey , more power to you. It's certainly your prerogative and I give kudos for gumption for sure. What I , and obviously other members up this page, hope for is no one gets brain damaged for trying. If you wanted to CTB crashing a car would you go and test it without using seatbelts and airbags? Maybe it's a flawed analogy but you can end up disabled with hundreds of thousands of (insert currency here) dollars , pounds ,euros.... in care and medical bills perhaps ongoing until death which could be years or decades. I know that Tired Horse tested his exit bag and removed it before the inevitable but his was constructed properly . But if you're not using the "knowledge obtained" correctly , what good is said knowledge? Why not just say " I've read everything on SS in the megathreads and now I'm going to do it my way" ? It's always a risk but why increase risk ? Again , not being critical. My name is It's My Life because I'm not going to be told how to die or waste away in a damned bed in a long term care facility. Good luck out there

It helped me out going through the steps and feeling calm about it and experiencing the sounds and the feelings.

 

[Jdieiejdjaow]

and experiencing the sounds

Sounds?

 

[Intoxicated]

That's a really flawed analogy, because the degree of the risks is incomparable. From what I know, there are lots of people who have tried gas asphyxiation using various gases (helium, nitrous oxide, difluoroethane, propane-butane) with recreational purposes, and complications with health or deaths from doing such things just a few times (not systematically) are exceptionally rare.

 

[AllAloneAndSad]

Sounds?

Yes. When the bag is filling up over your forehead and you bring it down and you hear the nitrogen in the bag and your own breathing. I took the bag off and my oxygen level reached 47%.

 

[Intoxicated]

Ha-ha, I thought you meant tinnitus. It's a possible symptom of gas asphyxiation which I had with nitrous.

Did you, @AllAloneAndSad , experienced tinnitus?

 

[AllAloneAndSad]

Did you, @AllAloneAndSad , experienced tinnitus?

Not really. I am over 50 so it didn't change much I guess. But it was very peaceful. It does take 6+ breaths to get the oxygen levels to 47%...not 2.
