Method Exit bag and inert gas megathread

[thegoldengirls]

Well that certainly sounds uncomfortable and stressful, I can sympathize you seek alternatives.

I'm no expert with the hoods but since the nitrogen directly flow in the mouth area and have co2 valves it is a superior setup, comfort wise at least.

The best setup is arguably still scuba/scba but the hood is still an upgrade from the bag.

Other than the hood you will need to connect the hose with the regulator, the hose is often quite short so an extension is often used. There is guides on the hood tread but no major components are needed other then hose clamps and extensions.

Yes! It's a very distressing feeling. I hear @TiredHorse had this similar issue. That's why I will be logical and not make rash decisions and upgrade gradually. I've already started from the least inexpensive method, and that hasn't worked.
And reading your response gave me clarity, so, instead of making the extreme jump in purchasing SCBA gear, I purchased the hood instead at under 100 USD.
I will have to be patient being that I won't receive it until the end of the month. In the meantime, I already have a Nitrogen tank so at least I know I'm good in that department. Now, it's a matter of waiting and hoping my SI doesn't fail me when I attempt with the hood.

 

[Tears in Rain]

Holy moly.

Now I understand why some are deterred from this method.


I maybe a little confused, but a specialised regulator like this?

Looking at an image of Gasmonkey's setup, I can't seem to place if the item above is another variation of the piece circled in Gasmonkey's setup below? So, getting the item above would work?

It takes me time to process new information when I'm learning so if I'm way off, please anyone correct me.

You could hook up a SCBA mask directly to a normal gas regulator, like the one in your top picture, but @GasMonkey advised against it.
He advised to use the specialised SCBA regulators that firefighters use.

For the SCBA and SCUBA methods there are two specialised regulators used. They are different to the gas regulator in your 1st image. One SCBA regulator is hooked up to the cylinder, and a second regulator is attached to the front of the SCBA mask.
You don't use the normal gas regulator, the one in your first picture. Those regulators are used in the exit bag and hood methods.

In your 2nd picture, @GasMonkey had a German/EU SCBA setup. So the silver thing attached to the cylinder is the EU/DIN SCBA adapter. The 1st stage SCBA regulator is screwed into that(the black thing at the end of the SCBA hose).

Look at the SCBA megathread for all the info you need. You're right, it's complicated on first viewing, but if you go over the posts on that thread, you will eventually get it.

Have you @Tears in Rain used SCBA in your setup, or the standard exit bag?
I wonder what chances are of having SI with this setup, it would suck to spend all this money only to have the same obstacle I have with the exit bag.
The thing with CtB is that if one invests in different methods under the guise that they'll be gone anyway, so who cares about the debt. But having the methods not work, while piling up debt is no fun.

No, I have the hood setup. I mentioned here previously that I tried it once, but S.I. got the better of me. I didn't time it, so I don't know how long I lasted before ripping it off. Other stuff came up in my life after that that led me to putting off another attempt, but I think I will stick with the hood.

Hey all, can anyone help me with figuring out what the second valve on this regulator does?

View attachment 132391

I did a test with an exit bag, and the big valve is most definitely the pressure valve. I opened up the cylinder valve, and then started adjusting the pressure to 25LPM (I have an Argon tank), but the hiss coming out of the hose was pretty quiet to what I expected. So the bag was filling up slowly (35x43cm), and when it did eventually fill up, I exhaled completely, pulled down the bag and took a deep breath, which immediately depleted the bag almost completely and then it wouldn't fill back up quick enough. So panic response set in and I had to abort.

Hence I tried messing around with the second valve (the small one). Facing it, I rotated it counter-clockwise until it wouldn't budge, and that's when the hiss coming out of the hose became audibly louder, yet the pressure still read 25LPM for output. So I reset, and when I pulled down the bag and took a deep breath the hose immediately filled it up again. No panic response and vision started going dark after my second breath.

I am asking because I don't know what the second valve does exactly and I am afraid to deplete the tank too fast. @Tears in Rain You seem very knowledgeable on this method, so your input would be greatly appreciated. Thanks in advance!​

You're regulator looks like an EU regulator. I'm not familiar with those, they look a bit different to U.K. and U.S. regulators. @Elzar was discussing those EU regulators a couple of pages previously on this thread.
I previously linked the below YouTube video about EU regulators. You may find other helpful ones.

 

[Coconteppi]

Sorry to bother again! Does anyone have a good link or place to get an EEBD hood? I'm just not sure where their could be cheaper or delivered faster.

 

[color_me_gone]

I feel like the videos of the Dr.Philip Nitschke, he makes it seems so easy. I guess he's a good salesman first. "After two breathes, your unconscious. "

Yeah, when I read that, I said Hot Dog, this is now my methed. Then TiredHorse failed several attempts, due to the length of time. That's when I realized that two breaths must be an outlier.

 

[bluehawk]

hello im new, I've been reading the forums here off an on for the past year. I did purchase my own nitrogen tank (last year) and followed the steps to create a bag from one of the videos I found online.

but after reading here in this thread it seems some were not successful. I dont want to fail, I'm at a point now in my life where I just want to go thru with it. I dont know a way to safely get the SN ppl have spoke of on the site here and other sites ive found. But I do have my own tank its been sitting in the corner now for bout a year never unsealed.

when I do this I dont want to fail, ive tested tonight the bag itself without connecting the tank. Just decompressing all the air out and seeing thru the foggy bag I felt abit lightheaded and felt my body wanting to gasp for air but I continued again without the tank & regulator connected.

some may ask why? well at my age I just dont want to go thru the daily fight & grind anymore. I'm tired of it all and have been considering this since early 2020. Ive tried my best to avoid using the tank but its time. I just dont want to fail when I do.

Any suggestions from those who tried and failed? Id appreciate it thank you. Also how fast is the knock out if successful?

Hi, I haven't tested the bag myself but I can answer some of your questions.

First of if you successfully constructed a functioning bag with elastics and tubing for inert gas you have a high probability of making it. The biggest hurdle people face is overcoming the panic and instincts to abort and rip of the bag. Some have had problems of feeling suffocated and hot which makes the temptation to abort a real problem. But since you already tried it without gas and almost passed out I think you will have less problem with this method.

Once you become unconscious the biggest risk for failure is either the bag removes itself from falling or someone finds you and "saves" you.

Its important to secure the body so when falling over from unconsciousness one does not rip the bag of and it stays on. Use a comfortable chair with arms and secure yourself with pillows to ensure this or straps. It takes approximately 15-20 min until death so it's crucial that you are alone for a few hour atleast to ensure. Almost all failures has been before one becomes unconscious, after that line has been crossed not many survive to tell the tale.

Some say it takes 30-60 seconds to become unconscious but it seems to vary it may take longer. The important variable here is to decompress the bag first to ensure it only contains inert gas. Secondly to take a deep breath and clear out your system of oxygen which will be replaced by the inert gas. The less oxygen the body have the more it can be replaced with inert gas which equals faster unconsciousness.

Hope this answer some of your questions, I'm happy to answer any more.

Thank You appreciate your reply, the bag I constructed I just followed the video that is online by the Asian guy. I used the porous medical tape bought at local store then used an turkey oven bag and just a twine similar to what he used in the video with a cinch clip. I followed the instructions exactly how he made his bag exactly.

the part I am concerned about is the bag being removed at the last few seconds before falling unconscious. No one is around I am in my own place so no interruptions I am thinking will this work if I am laying down on my bed with the hose taped inside the bag on the side instead of the back of the head. This way when I do fall unconscious there is no risk of the bag being disturbed or falling off.

the images ive seen drawings of sitting in a chair which I do have but perhaps laying down might be better? Also ..... is there anything I can consume that will insure to lessen the possible panic of removing the bag those last few seconds? Something accessable? I dont drink never had a drinking problem infact I havent had a drink in many many years. I was thinking sleeping pills? I donno I just want to go I am tired of this fight and struggle and I dont want to ever come back Ive well over paid my dues and just want to exit this world forever

If the hood would somehow be removed while falling unconscious you would simply wake up feeling quite confused and disoriented and possibly with a hell of an headache, but you would recover. This is one of the benefits of inert gas, nothing really permanently affects you if you abort before unconsciousness.

No one is around I am in my own place so no interruptions I am thinking will this work if I am laying down on my bed with the hose taped inside the bag on the side instead of the back of the head. This way when I do fall unconscious there is no risk of the bag being disturbed or falling off.

There is some mixed opinions about lying down, I suspect they are worried about the overpressure being compromised and let air flowing inside the bag. I would personally not lie down and instead use a wingback chair with pillows or something equal.

I'm not sure, you would have to be somewhat clear in your mind to proceed with the necessary steps, alcohol would make it easier but would risk making a mistake. I plan doing it at night when I'm really tired, no alcohol out of principle. In my country they perform autopsy and I intend to go with a clear mind.

 

[bluehawk]

I have a wing back chair that reclines, I sorta tested it abit ago with my arms on the arm rests and just left them fall to the side off the arm rests. The chair i reclined abit back at a 45 degree angle I do have a neck pillow I can place behind my neck but will also be against the back of the bag behind my neck. That would keep my head upright from tilting to the side..

my bag doesn't have elastic Ive read some ppl secure the bag shut and some leave the bag with a gap??? to release CO2? I've watched those videos online from Dr N i forget the spelling of his last name but he makes it seem so effortless.

I just don't want to fail

I want to be sure this works but I can not afford one of those scuba masks but I do have all the rest of the equipment and my tank has been unsealed and secure/safe. the Tank size is I believe when I bought it like 20L?

I tried to find the receipt but I think I shredded it a while back. The tank stands 15inchs height not including the turn nozzle up top or regulator. I haven't attached the regulator yet but it is the correct size and does fit.

The tubing and hose clamps I've already tested last year and cut to size so that the tank wont be interrupted fall or be tipped. I'm going to place the tank in a box filled with clothing to support it standing upright.

Going to clean my place and prepare, I just dont want to fail like others have doing this method. I would have gone the other routes SN and the drink option but I could not find any of those available back when I was able to afford that stuff. The tank however was my only option available so I bought the tank last year.

I just dont want to fail, I do not want to return

when I did test last night without the tank connected when the bag fogged up I did feel the need to gasp but pressed forward till I was about to pass out then I lifted the bag. I hope to just faint straight away at that point when the tank is connected and gas flowing, just like Dr N mentioned in his video.

I appreciate the feedback btw thank you Kapsyl

This sounds like suitable and quite comfortable last place the end and inline with the recommendations.

I believe the elastic is necessary to ensure the bag contains enough inert gas lower the oxygen in the blood. 15/lpm wouldn't be enough to push out air without the elastic.

I believe you will fail without the elastic, the air will overcome the overpressure with that big of an opening. This will result not enough of inert gas and you may not loose unconsciousness or it will take a real long time. If the oxygen level is high enough to support life but not consciousness and the bottle runs out of gas, you may survive with brain damage. Check the guides on exit bags again to make sure.

Make sure you have atleast 400 liter of uncompressed of inert gas, I don't think you have 20 liters by your measurements since a 20 liter tank would be quite big. You need continuous 30 min of gas flow to ensure passing away.

It should be easier with the inert gas since you probably won't experience the feeling of air running out but rather only the co2 build up and heat.

My days are mostly lonely and pathetic, it gives me something too be able to help others even if it's a grim subject, your welcome.

 

[Coconteppi]

Any recommendations for what brand of turkey bag works well? Is there better one than a generic one from walmart or are they all relatively the same?

 

[bluehawk]

ok I found the receipt for the tank I bought back in 2022. it reads as a 2.2 compressed, 20 CGA 580 Traveler, cylinder 20 CF Steel. My regulator is 200 to 580psi

I bought a tank that resembled the size of what Dr N shows in his videos and other videos ive seen online about nitrogen. The price was expensive for the tank and nitrogen 300.

I checked to see how many liters and I dont know how to read the size on the receipt, but the tank itself looks like the same size as the videos. If this is not my way out I dont know any other way that is accessible.

there has to be a way with what I have. I do have a gas stove in my place and my place is small ventilation is not great at all but I donno how to make this option work for me. Any suggestions would be helpful I want to leave

What I have found it sounds like you have a 20 Cubic foot bottle which equals as 560 liters of nitrogen or 37 min of nitrogen at 15/lpm. Did you buy it empty? Most sites seems to sell it empty, do you know the purity of the gas?

What kind of regulator do you have? Can you set how many liters per minute or just the pressure?

 

[bluehawk]

purchased tank is filled with nitrogen and the regulator. before I left I had one of the staff show me on another tank like mine how to connects I wanted to be sure it was the correct regulator. I can adjust the pressure on the regulator he showed me how and from the video it said to set at 15 or something in my notes. The brand is by company Victor Cut SkIII that is how it reads on the regulator.

my tank is still sealed there is a shrink wrap around the nozzle and the turning thing

my gas stove however is propane and there have been times when the pilot light has gone out and I can smell the gas and it has woken me via headache. But ...... at this point Im open to all options.

I guess I could just turn off the flame and keep the gas running close all the windows and let the gas from my stove take over. Thing is when I start to smell the gas it wakes me up but I've seen stories on youtube where ppl just dont wake up and well the end result. Maybe that will work but I need to stay under and not wake up when the smell kicks in.

Based on the tank information on the receipt I shared do you think I have enough? Will it work? I have extra turkey bags and am thinking of going to the sports store and get one of the elastic headbands and copy from the images ive seen online. My current bag tho I copied from the Chi guys video exactly how he made his. I just dont want to fail.

Well I can probably guess you didn't tell the staff what your true intentions were so I'm not sure what they set it to. 15 is liter per minute and is not the same as pressure, please check before trying. It's generally advised to have a flow meter to know exactly how much gas is flowing and it's not the same as outgoing pressure.

The exit bag I've seen are with elastic headband or something equal, I would search for more guides.

As for your setup it has potential but there are some questions left with the flow meter for example and what purity the nitrogen is at.

 

[bluehawk]

before purchase I mentioned I would use it for a party for the weekend and needed the best purity possible If I remember right they mentioned 97% as for the regulator i mentioned the staff guy who sold it to me that I need to know where the 15 mark is and he showed me on the gauge. I guess I'll look for what you mentioned a flow meter.

The regulator i have reads on the lable 250 series Victor CutSkill or CutSkIII it has 2 gauges attached both read as psi. Gauge 1 reads from 400 to 2800 the other reads from 4000 to 28000. The regulator was expensive that part I very much remember same with the tank of nitrogen. But back then when I did have money I didnt even bat an eye when buying it.

I wish there was a way to get the SN ppl mention here on the site but I have no idea where to go for that. I am thinking more now to just use my kitchen gas stove and park my chair in there and take some sleeping pills or something to not wake up when I smell the stove propane.

 

[CTB5656]

Has anyone tried buying one of the pre-filled 2.2L Nitrogen tanks that come with a regulator off ebay? Seems like an easy way to get most of the setup, and I don't want to buy from a local supplier at the risk of looking suspicious.

 

[Elzar]

I tested my Exit Bag, complete with helium flowing, for the first time today.
I did "dry runs" before with just the bag a couple of times and didn't find it very irritating or suffocating, even though I did leave it on until I was starting to get dizzy (so quite a while).

This time, with the helium flowing, I did find it suffocating.
Strange, one would think it to be exactly the other way around, right? Maybe I sensed the drop of my oxygen level?
Most likely it's just me not really exhaling properly beforehand...

Anyway, it got me thinking about the size of the bag.
My current one is pretty small (39x55), about the same as the bag in the "A Dignified Helium Exit" video (the bag there is 45x50).
The PPeH descripes a bag of 35x50, so mine shouldn't be too small, plus I have a small head.

What I didn't really expect was how much the bag contracts when inhaling and expands again when exhaling.
It's probably exactly how it's supposed to be, but in my mind the constant flow of gas should have "filled up" the bag again even before I exhale.
With the bag contracting and expanding so strongly through me breathing, it feels like I am re-inhaling too much of my exhaled CO2 again...

You shouldn't feel any suffocation. Maybe up the LPM to 25 LPM, if you have plenty of gas.
I would probably use 25lpm for both hood and bag methods, once I had plenty of gas.

I am thinking more now to just use my kitchen gas stove and park my chair in there and take some sleeping pills or something to not wake up when I smell the stove propane.

Using propane or natural gas to asphyxiate is very dangerous.
When the gas reaches the right concentration inside your house, the slightest ignition source will cause the gas to explode.
Your entire house will blow up like a huge bomb.
If you have neighbors, they could be injured or killed.
After the explosion, a huge fire will burn the remaining contents. posing a fire threat to neighbors, as well.
I got the above image by Googling "cooking gas explosion".
A lot of people don't like cooking with gas for this very reason.

I would probably use 25lpm for both hood and bag methods, once I had plenty of gas.

yeah, I'm kind of conservative because I'm still not 100% sure the regulator gives me the correct lpm, but I'm pretty sure it's been at least 15lpm.
In your opinion, should the bag "fill up" the inhaled gas quickly enough to noticeably expand back even before I exhale?
When all I'm inhaling is helium, do I even exhale CO2?

Thanks. 22" is about 44x55, I think. That's not too dissimilar.
My bag may be a bit slim, which might make the contraction more noticable.

 

[thegoldengirls]

So, I purchased the EEBD hood. Hopefully, having the a lesser restraint than the plastic bag will help alleviate the SI.
Meanwhile, I wonder how common is ctb with the gas Nitrous Oxide? SI is such a strong factor in these inert gas methods, but with Nitrous...it causes euphoria, so I would think the euphoria would overpower the SI, hence, a successful ctb? I'm in the process of reading articles about it.
Apparently, a man in the US successfully ctb.
The only type of Nitrous Oxide I can get get my hands on may have a little bit of air in it.
I wonder if that's standard?

 

[Tears in Rain]

No idea about how quick an exit bag fills up after each inhalation. Obviously there should be enough gas in the bag to cover each inhalation.
But I've never used one, so don't know.

I presume when you inhale helium that you will exhale both helium and CO2. The body doesn't use the helium. But not sure how much CO2 gets exhaled, as CO2 gets created after O2 is used in the cells of the body. There will still be O2 in your system after pulling down the bag and inhaling the helium. So CO2 will continue to be exhaled until the body is depleted of oxygen.

Yeah, I remember you talking about using helium with an argon regulator. I would up the LPM rate, and see how you feel.

 

[Elzar]

Yeah, I remember you talking about using helium with an argon regulator. I would up the LPM rate, and see how you feel.

I guess I'll have to try that. Didn't want to touch the new tank, but that stuff I better do figure out beforehand.
Might try a bigger bag as well, then...

That may be off topic but aren't you afraid that someone calls 9/11 when they hear gas leaking? I'm planning to rent a house because of it. I was curious why this wasn't a topic here.

It's really not that loud, at least not my setup at 15/20 Lpm. It can appear loud when using an exit bag since the hose will be right by your ears which is why some use earplugs to block it out.

Use some music to mask the sound, doesn't even have to be loud but something too making it undetectable even if someone was really trying to listen in.

I plan doing it my apartment and see no problems of detectability from neighbors, but I would probably have some music in the background.

I made a thread about my failed inert gas attempt:
https://sanctioned-suicide.net/threads/helium-attempt-failed-possible-explanations.156835/

 

[Tears in Rain]

I made a thread about my failed inert gas attempt:
https://sanctioned-suicide.net/threads/helium-attempt-failed-possible-explanations.156835/

In the begginning of past month I had one failed attempt with gas setup (an industrial helium tank with 99,99% purity declared, a flow control, an exit bag). I just woke up when the gas flow ended.

Now I understand that made at least two mistakes.
1. I kicked a tank off while being unconsciousness. So it fell on the floor (tubing still was okay, it was even hard to remove from a flow control). The instruction of the flow control says it is forbidden to use in the horizontal position. I have read somewhere when the tank lies horizontally, then liquid fraction of the gas will go to reductor/flow-control, not purely gaseous one as it should be. And therefore most regulators/flow-controls do not work correctly in horizontal position.
I hypothesize that due to that mistake the gas might flow way too fast after the fall, so I did not get enough exposure to hypoxia (sadly I did not mark the timespan of unconsciousness).
I should had tied the tank to the leg of the chair or probably buy a special gas stand for that.
I think that's the most likely explanation of my fail.

So you knocked over the tank when you went unconscious? You should always ensure the cylinder can't fall over.

I previously posted this from the PPH:

2. I had opened the tank very slightly, because it seemed more than enough to set 15 LPM (the knob of the flow control was also opened minimally). The arrow of the flow-meter was jumping from more to less, but it seemed like on average it was about 15 (the flow was enough, judging by the fact that I lost consciousness very quickly, just in a few breaths).

Now I have read already on this forum that I should open it at full, but it seems like no one here explained exactly why. Who knows, what exactly goes wrong if you open it slightly and how likely is it to be the reason of failure?

Yes, open the cylinder valve fully, then set the LPM on the regulator. Apparently it can damage the cylinder valve if you don't open it fully when the gas is flowing.

3. May be the exit bag collar was not snug enogh. There was some space between the neck and the collar of the bag, so I could enter a finger here without stretching the bag. Is it to much space?
I think maybe that matters more when you lie than when you sit. I started sitting on the chair, but ended up lying on the floor (fall off while unconsciousness).
If that's so, then it would be better to tie myself to the chair, not only the tank to something.

The PPH says the bag should be snug but not tight around the neck:



You were using helium, are you sure it was high purity?
Did you use a helium gas regulator/flowmeter?

I'm scared I'd fail the bag method if I tried it. It seems complicated after reading about regulators, valves, maintaining gas flow etc. I'm tempted to just use it in a car instead. How many ~ liters of argon gas would it take for a small car to fill up enough? Would you still need to use a regulator to control the gas flow? How do you know if a regulator will fit your gas container? Is it a one size fits all type of thing? Sorry if this has been discussed many times before.
