Method Exit bag and inert gas megathread

[Tommen Baratheon]

Anyone have any thoughts on if this is reliable and enough gas?

Probably not in both cases. I bought something similar to test and the percentage of helium wasn't even mentioned on the tank. Also, a lot of reviews stating it didn't come close to filling 100 balloons.

So I found a couple local dealers who sell/rent larger tanks with over 99,9% purity.

OK so I figured out my problem, and I think the problem someone else was having with argon. There is a difference between a flow regulator and a flow meter. A flow regulator regulates the pressure to produce the desired flow, and it's not very accurate. These are the ones with two dials. A flow meter has the ball in it and accurately measures the flow of the gas. I will be verifying this today as my flow meter is on the way, but the flow regulator resulted in a severe co2 reaction, with slow bag inflation.

@Msvr Hey there, I'm wondering if I should restrain myself when doing this, I keep thinking it's no big deal I'll only twitch slightly, not enough to flinch or remove the bag, and so I'm wondering is the risk worth it?

I do plan to restrain my wrist, though as you said it's probably unnecessary. I used some spare elastic from my exit bag and created straps around my arm rest in such a way that I can semi-painfully squeeze my wrist into the strap. This helps hinder SI and prevent me from unconsciously removing the bag. Here's an example, with our lovely mr. Sonic giving us a demo.

The website description states:

"High quality helium: 99.99% pure helium, non-flammable and non-toxic, can be used at will with complete confidence. 25.92cu.ft of helium"

Is that perhaps 99.99% questionable?

The 99.99% Is personally unreliable. It is questionable if the manufacturer themselves doesn't say it's 99.99% pure, and this is because of how common it is to add oxygen to helium these days. Tommen Baratheon is right, it's not reliable esp because it's not mentioned on the tank.
I wouldn't bother wasting my time with it. You're better off getting nitrogen from a near by gas shop or wielding store.

Haha thanks for the picture! I figured it's not needed because the amount of bodily movements you end up having is probably low, but like you, I want to be really sure just in case. This is really creative, btw. I think I'm going to do the same thing.

 

[standingfast]

I am so frustrated. Can't find things locally at welding places. I just want to get out. Living sucks and the universe is still punishing me by making it hard to get out.

For me , this concern went away once I ran tests and se how it works .

When you scrunch all the air out of the bag prior to turning gs on , then allow the bag to inflate , once it's fully inflated .. it's fully inflated with nitrogen , with some residual oxygen that didn't make it out from
Scrunching . But . All of the gas / air inside is being replaced with fresh nitrogen at a high rate , and gets forcefully blown out of the bag , around the neck : you can feel the gas rushing at a high rate around the neck .
Theoretically, the elastic could like … not be tight at all, but the the slight positive pressure stops all ambient air from coming in . This being said , I still would prefer snug fit with the elastic
Once you play around with the tightness of your elastic , and conceptually understand the positive pressure of the bag, and experience it , you'll feel better
You could also just put the bag over your head and tighten the elastic without any gas flowing , to get a sense of the positive pressure. Put it on and press on the bag and notice that the air in the bag doesn't really escape unless you pres hard enough .

Also , you could just get a dummy head , and oxygen sensor and run a test on the dummy head
I did this a few times, and the air in the bag ws like 95-96% Once tho e bag ws fully inflated . Then as more air gets pushed and replenished by fresh nitrogen this slowly crept up to 97..98…99 over a couple minutes

what about an Eebd hood? Seems like there's be a lot of residual oxygen left behind.

Mine looks like this.


What would the protocol be?
1. Allow the nitrogen to fill up the hood while it's on your head
2. Hyperventilate before pulling the hood down which with isn't really fast. Might have to practice holding my breath for atleast a minute

Is there anything I'm missing?

Check out the mega thread on eebd.
For eebd most people say you don't have to hyperventilate since your exhaling co2 from the purge valve .( these work like shit from my experience which is why I won't use this method ,so definitely make sure your purge valve works )
Also recommended higher flow like 25 lpm.

Basically same concept as exit bag just added benefit of purge valve

99.99% Is personally unreliable. It is questionable if the manufacturer themselves doesn't say it's 99.99% pure, and this i

The manufacturer wrote me saying:
"The helium gas filled in the tank is electric grade purity reach up to 99.99%"

 

[CantDoIt]

The manufacturer wrote me saying:
"The helium gas filled in the tank is electric grade purity reach up to 99.99%"

" Up to" 99.99%? What exactly does that imply? I feel like the phrasing there is vague.

I agree with this. I still don't trust it. I would just buy your inert gas at a wielding shop.

 

[standingfast]

buy your inert gas at a wielding shop.

I will have to find it locally. I have been having a hard time with that search.

 

[kudaphillips]

Just get an o2 analyzer . Very cheap an accurate .

 

[standingfast]

This is what they told me about the helium purity

 

[kudaphillips]

View attachment 151292This is what they told me about the helium purity

Even if they assured you it's 100% helium guaranteed . Why would you even trust them .i don't f-ing trust annyone , let alone someone selling me something . Everyone needs to test their gas , even if from reputable vendor . Get the cy-12c oxygen analyzer only way know for sure

I tried, but nothing happend. I didn't lose consciousness for a long time. What did I wrong? It seems to me the flow rate 21 is small

 

[Allla]

Я пробовал, но ничего не получилось. Я долго не терял сознание. Что я не так сделал? Мне кажется, что расход 21 маловат

Тhe bag is filled very long

What gas did you use and is it above 95% purity?

Will you tell me more on why the purge valve works like shit?
How do I check that mine works?

The scuba method isn't possible where I am. Hard to find adaptors because of the build of the tank is different to western ones to begin with.

 

[Allla]

Какой газ вы использовали и имеет ли он чистоту выше 95%?

я have N 99,9999

 

[Shunya]

Well, you just put it on and breathe in and out into the opening, and you can tell when the air is exhaled out the valve because you can feel your breath either coming back and hitting you in the face or you can feel it going through the valve if you put your hand up to it. If I secure the valve with my hand over it, I can get it to work but as soon as I take my hand off, or moving around it doesn't work correctly. The method wud still work even with purge valve not functioning correctly , but then it would essentially just be an exit bag

Yes. There's no band in the hood to hold valve in place. But can't I hold it manually from outside? If the valve doesn't work, or if I cannot hold it in place, does that mean that there will be residual air and that it may cause any complications?

When you say that you won't use this method, do you mean nitrogen or just the Eebd hood that you wouldn't opt for?

If given the choice between sn, cyanide and nitrogen
Which would you choose?

В прошлый раз, когда кто-то сказал, что это не работает, проблема была в их сумке и резинке, поэтому нам было бы любопытно посмотреть, как выглядит ваша сумка. Кроме того, предположим, что вы проверили свой газ с помощью датчика O2, и он был выше 99%? Отправьте всю вашу установку.

Ну, вы просто надеваете его и вдыхаете и выдыхаете в отверстие, и вы можете определить, когда воздух выдыхается через клапан, потому что вы можете почувствовать, как ваше дыхание возвращается и ударяет вас в лицо, или вы можете почувствовать, как оно проходит через клапан, если вы поднесете к нему руку. Если я закреплю клапан рукой, я смогу заставить его работать, но как только я уберу руку или подвигаюсь, он перестанет работать правильно. Этот метод все равно будет работать, даже если клапан продувки не будет работать правильно, но тогда это будет по сути просто выходной мешок

Ну, проблема с регулятором или сумкой, как я уже сказал, в прошлый раз у кого-то была точно такая же ситуация, проблема была в сумке и резинке.

I сan't screw to the end

Yes, you could hold it in place until you pass out I suppose. The only complications the purge valve not functioning correctly would cause is that your hippocampus alarm may engage from buildup of CO2 from your breath. Like I said, it still will probably work fine, but it just defeats the purpose of going, Eebd route if the purge valve isn't working. Yeah I'm probably not gonna go the Eebd route for this reason, I feel better about the exit bag personally. I don't want to trust my life to some cheap Chinese equipment. Turkey bag easy to check for leaks, durable should work just fine. I'm not married to any of these ideas also but currently it's the one that I prefer I'm always open to being persuaded. I could also go shotgun method if I wanted to sometimes that seems like the best route, but it's just tough when that barrel is in your mouth it's no joke.

I don't know much about cyanide. If I had sodium pentobarbital or nembutall that I was 100% sure was potent and pure I suppose I would go that route.

Is that rope or elastic on the bag ? Show closer if of the elastic and do you have a toggle ?

Yes, the rope is elastic.

Maybe that's the problem, you should be screwing the regulator on all the way, or leaks will happen. If you have leaks in the setup, it'll take longer for the bag to fill up. But if you can't screw it all the way, you should get a different regulator.

 

[Allla]

Может быть, проблема в этом, вам следует закрутить регулятор до упора, иначе будут протечки. Если у вас есть протечки в установке, то мешок будет наполняться дольше. Но если вы не можете закрутить его до упора, вам следует купить другой регулятор.

Тhank you, I will think about it)

The tube length looks okay to me.

How long did the bag take to inflate when you had it around your forehead? It should only take about a minute, maybe less since you were using a higher LPM.

Can you feel any leaks around the regulator?

 

[jamesu7777]

Would this work for an exit bag?

Amazon.com

 

[Allla]

Длина трубки мне кажется подходящей.

Сколько времени потребовалось, чтобы надуть мешок, когда вы надели его на лоб? Это должно занять около минуты, может быть меньше, так как вы использовали более высокий LPM.

Чувствуете ли вы какие-либо утечки вокруг регулятора?

Более 7 минут. The bag was not straightened.
I don't feel leaks near regulator

Inner diameter of the tube must be 6 mm or 9 mm?

 

[Allla]

Я понял. Это неправильный редуктор. Я много раз спрашивал о 15 л/мин и продавец сказал Да, но сегодня он пишет очень маленькое значение. Красные цифры означают не литр/мин, а м3 в час

 

[Allla]

Мay anybody give me a photo with the scale of normal reducer? Please) I need it very much

 

[LeoSS]

Help me understand. The flow rate is supposed to be 15 liters per minute(LPM). The regulator gauges are in PSI and BAR. What is the flow rate that I'm supposed to set in PSI or BAR? Thank you.
