Just finished putting together a nitrogen exit bag setup

[outrider567]

Thank you!

Does the ball have to float up to where I marked with the red line in the image?

What do you think of click style oxygen regulators? would it be simpler or better than the argon regulator? The one I found only goes up to 15lpm.

Mine is click-style, 25 LPM is recommended for the EEBD Hood

I can't find one that goes up to 25 where I am. I suppose I'll have to stick to the argon regulator then. Thank you!

 

[NegevChina]

That regulator looks like it will work.


I'm not sure about other countries, but in the US all inert gas cylinders use the same connection so adapters aren't required. I would guess that you won't need an adapter, but you might find more conclusive information on the other SaSu inert gas threads.


The supplier fills up the cylinder to a standard pressure, so it should be the same for any gas. The instruction manual for the meter I bought said it works for any inert gas, and I assume that's true for all of them.

Turns out the flow meter that fits the Nitrogen tank threading in my country is a CO2 flow meter. Will that still be good?

Yes, tachycardia has happened all 5 times I tested on myself, totally normal reaction of the heart, the heart doesn't like being without oxygen

Not less than a second, a minute or so, with my tests--With your oximeter on your fingers, you can watch the O2 level going down, but remember the delayed reaction--At first, you're thinking, 'is this thing even working?' the first couple of breaths, but once it goes below 80, you better decide quick to either proceeed or take the EEBD Hood off , because after I took mine off, it still dropped all the way to 40

No need to hyper ventilate in my tests at 25 LPM, or to fill up with Nitrogen beforehand, but nothing wrong with doing that if you like

This is the first time I see tachycardia mentioned with this method...

A minute ? An entire minute ?!

Sorry but testing with an EEBD is quite wrong, cause it's VERY unlikely you have time to decide to pull it off. Testing with SCBA on the other hand has the advantage of being an automatic abortion of the process if it's not attached behind your head and then it falls once your head goes down from unconsciousness.

The method clearly implies you get rid of the oxygen in your lungs and keep it that way until you slide down the EEBD that was on mid-head filling with N2 but you also have to squish it beforehand to get rid of the oxygen.

Something's wrong with what you did and you could have died without knowing and less peacefully than the method is designed to.

NEVER use an oxygen regulator.

ONLY those designed for inert gases (Argon, Helium and Nitrogen)

Tachycardia is common with Nitrogen CTB, as I've explained--But I must clarify when I said a minute, I really meant less than a minute, more like 20 to 30 seconds, sorry about that--Well, of course there's 'something wrong with what I did', as I've stated in other posts, this is a dangerous test, I easily could have blacked out when the Oximeter hit 77, because the real number was actually 40, with the delayed reaction--A few more breaths and I wouldn't be here right now, no more tests for me--And, you're correct that one should never use an oxygen regulator

How about CO2 regulator? I just ordered one.
Its the only one that has threading compatible to Nitrogen tank in my country.
This table ShatteredSerenity posted suggests its possible:

[panda55]

Is the oxygen meter necessary? Do some nitrogen tanks not have pure nitrogen?

Testing is best practice (trust but verify yknow) but you can check with supplier and also cross reference any grade (if applicable) w/ the standard (eg food vs industry vs xyz)

The regulator did not include any sort of hose connection, just a 5/8" - 18 female outlet. I tried searching for fittings in the local hardware stores, but it turns out this is a pretty specialized connector type specific to inert gas, so I ended up having to go to a big gas supplier in the industrial part of town to find it. You'll probably want to order this online, unless they happen to stock it at the place you buy your nitrogen from (the welding shops I checked didn't have it either). The part you need is called an "inert gas nut and nipple." The kit they sold me came with a hose clamp, a 5/8" - 18 nut, and a barbed nipple sized for 1/4" ID hose.

I picked up 1/4" ID x 10 ft PVC clear vinyl tubing at the local hardware store. It's flexible enough and it doesn't have any smell, so it seems fine for this application. The hose clamp included with the inert gas nipple was too large for this tubing, so I also had to get a smaller one from the hardware store. I had to run the end of the tubing under very hot water for a while to soften it up enough to push on the nipple.

This is how nut and nipple look (if you shop online it may not include the hose clamp on the left, which is fine since it would proably be the wrong size anyways):

Thank you so much for this detail! Seems I might have the same kind of outlet and was struggling to figure out what to do for connecting to a hose barb and hose.

 

[RiverOfLife]

Thank you! This is a method that appeals to me but it seems so complicated so I appreciate you breaking it down.

I have just been reading " Inert Gas Cylinder & Regulator, General Refresher Summary" written by fightingsioux,
According to him ( a welder):

It doesn't matter if the regulator is being sold as an argon/oxygen regulator or a nitrogen regulator or what gas you're using. For your purpose, any combination will work.

 

[devils~advocate]

In the USA, the connection to an inert gas like N2 would be called 'CGA-580'.

There are a variety of regulators that use this connection.
Some are marketed for Nitrogen, but any type should work (i.e. argon, etc).

There are 'click' type regulators: https://www.wtfarley.com/Nitrogen-Click-Style-Regulator-CGA-580

Some are more expensive than others....but Im just not sure if there is really a correlation btwn cost and quality.
Ive seen many that look exactly alike but the prices are vastly different...usually on who is selling it. So research extensively.

Not sure....they posted a lot & one would have to go thru all their posts to get a sense of their reasoning.
I would assume they don't trust the method.

 

[zardofan]

All the trouble for the gas setup ending with taking Sn, sorry for my poor eng, i wonder why??

I asked him in one of the threads, don't remember where, because I had just changed from SN to N2. He said when he attempted at the hotel the first time (dec 2024 I think?) he flinched and took off, leaving all the stuff behind. He didn't want to go through the process of acquiring all of it again.

I learned a huge amount from him. Hope he found his peace.

 

[devils~advocate]

Ok come to think of it, I seem to remember something about this....leaving it all behind in a hotel.

His N setup in this thread is spot on. Classic textbook per the publications that describe this method.

 

[Tommen Baratheon]

I just thought I'd share a description of the gear I put together for inert gas asphyxiation with nitrogen and an exit bag. It's pretty basic since I felt it would be better to start with something simple and functional, then upgrade to SCBA/SCUBA or something else in the future if I have time and can obtain parts.

I'm located in a suburb in Washington State, and it was straightforward to find everything I needed either locally or online with 1-2 day delivery. For the things I needed to order online, I had them delivered to an Amazon Locker nearby to avoid any awkward questions since I live with my family.

Here's the tank, regulator, and hose:

View attachment 155034

The nitrogen tank was easy to buy at a local welding supply store. I had never bought compressed gas before so I was a little nervous, but everything went smoothly in the end. Before going to the store I did do some research into using nitrogen for home brewing in order to have a plausible cover story in case they asked what I was planning to use it for. I'm glad I did because they asked twice and the cover story worked flawlessly both times.

I tried asking about the purity of the nitrogen, and they just said said it was industrial grade (which doesn't mean much if anything). Then they asked what I was using it for, and I said I'm getting into home brewing. That got her chatting about a customer who gets little bottles of nitrogen for wine, and she said it works great for that so it should be perfect for my needs too. That didn't exactly help me satisfy my concern about purity, but it at least deflected her away from the topic of what I'm actually planning to use it for. I ended up tested the purity of the nitrogen myself with an oxygen meter and it contained 0.0% oxygen, which is about as pure as it gets for my purpose since all I care about is oxygen contamination.

When I went to buy the tank I asked what sizes they had in stock, so again they asked what I needed it for, and I responded that I was putting together a home brew system. The guy got interested so he asked what kind of beer, which stumped me (I rarely drink) so I just said my wife handles that part we hand't decided yet. They had 40 CF and 55 CF cylinders in stock, I was waffling between the 2 sizes but I ended up going with the 40 CF cylinder since it was shorter and easier to hide.

I decided to go with a combination pressure regulator and flow meter for simplicity. There are some very cheap regulators available on Amazon, but I was afraid they might be too cheap, and in particular I was concerned about it being too noisy. The regulator I chose was significantly more expensive, but not terribly expensive, and it's made by one of the main reputable welding supply manufactuers. It's well built, easy to adjust, and very quiet.

The flow regulator scales are calibrated for argon and CO2, not nitrogen, but the manufacturer provides a conversion table for a variety of inert gasses so that's not a problem. Nitrogen is lighter and less dense than argon, so for a given reading on the flow meter's argon scale, there will actually be more nitrogen flowing through the meter. According to the table below, approximately 1.19 times more nitrogen to be precise.

Most guidelines specify to use a 15 LPM flow rate to the exit bag, but the meter's scale is calibrated in units of SCFH (Standard Cubic Feet per Hour) instead of LPM, so you need multiply by the conversion factor 2.12 which produces a target rate of 31.8 SCFH. I rounded up to 32 SCFH for simplicity.

To get 32 SCFH of nitrogen flowing, we divide by the conversion factor 1.19 from the table below to get 26.9 SCFH on the argon scale. I stuck a piece of tape on the meter and marked it with a red pen to make it easy to set the target flow rate when I'm ready to use it.

The regulator did not include any sort of hose connection, just a 5/8" - 18 female outlet. I tried searching for fittings in the local hardware stores, but it turns out this is a pretty specialized connector type specific to inert gas, so I ended up having to go to a big gas supplier in the industrial part of town to find it. You'll probably want to order this online, unless they happen to stock it at the place you buy your nitrogen from (the welding shops I checked didn't have it either). The part you need is called an "inert gas nut and nipple." The kit they sold me came with a hose clamp, a 5/8" - 18 nut, and a barbed nipple sized for 1/4" ID hose.

I picked up 1/4" ID x 10 ft PVC clear vinyl tubing at the local hardware store. It's flexible enough and it doesn't have any smell, so it seems fine for this application. The hose clamp included with the inert gas nipple was too large for this tubing, so I also had to get a smaller one from the hardware store. I had to run the end of the tubing under very hot water for a while to soften it up enough to push on the nipple.

This is how nut and nipple look (if you shop online it may not include the hose clamp on the left, which is fine since it would proably be the wrong size anyways):

I bought an oxygen meter from an online store to test the gas. In the photo below the meter reads 20.1% oxygen in my house's ambient air. When I piped some nitrogen gas into the meter's inlet the oxygen reading went all the way down to 0.0, so I'm content with the purity of the gas in my tank. When the oxygen content droped to dangerous levels it started flasing red lights and beeping VERY loudly, which was super annoying and something you'll definitely want to watch out for if you use the meter with other people around.

The exit bag itself is a 19 in x 23.5 in (482 mm x 596 mm) turkey size oven bag. They were sold in 2 packs at the local grocery store. It's a decent thickness and reasonably flexible to cinch down around the neck. It's crinkly and certainly not the most luxurious headware for my last moments on earth, but if it comes to it this should get the job done.

I used a 1/4" elastic band from the local craft store to cinch around the neck, and I repurposed some spring loaded cord locks from an old backpack to set the neck band tightness. You want it tight enough to keep the gas in, but loose enough that gas can still flow out when you exhale.

I used 1" micropore tape from the local drug store to tape the bottom seam. It's flexible and adhered well to the plastic.

I live with family, so it's important for me to be able to hide the entire setup discreetly. Fortunately the 40 CF nitrogen tank is just short enough to fit in an old duffel I had laying around. It's nice to have a bag with an arm strap, because the full nitrogen tank is pretty heavy and awkward to carry.

My current plan is to ctb at a hotel in another city, and the rooms on upper floors require going through the lobby and taking an elevator, so it definitely will help to have the discrete duffel bag to lug the tank to my room without attracting attention. I was considering going with a 55 CF tank for extra certainty of enough gas for asphyxiation, but it would definitely require buying a taller bag, and I'd also really want something with wheels at that point.

Here's a breakdown of the materials and cost:

Item	Source	Price
40 CF compressed nitrogen cylinder	Welding supply shop	$204.65
Inert gas flow meter regulator	Online	$126.76
Oxygen detector	Online	$159.45
Inert gas nut and nipple	Gas supply shop (can get online easily)	$10.16
1/4" ID x 10 ft PVC clear vinyl tubing	Hardware store	$4.69
19 in x 23.5 in (482 mm x 596 mm) turkey size oven bag	Grocery store	$3.99
1/4" elastic band	Craft store	$2.49
1" micropore tape	Drug store	$3.79
plastic cord lock	Old backpack (can buy in craft store)	free
	Total​	$515.98

I'm not sure when exactly I'll ctb, but it removes uncertainty and eases my mind somewhat to at least have the means to do it in hand now.

The crinkly exit bag isn't particularly comfortable or elegant, and I would like to upgrade to a SCBA or SCUBA setup if I can source parts. I'm not sure it would be worth the extra effort and expense, though, considering that I'm only planning to be conscious in it for 30 seconds or so anyways. Upgrading my setup would give me something to work on if I decide to hold on to life a bit longer.

Thank you for your message (made a bookmark). The conversation table is/was one of the missing pieces in my own set-up.

600L (21 cf)
At 20 lpm.....30 minutes
Which should be more than enough for ctb

Id say at least 20 minutes.
At 20 lpm....that would be 400L at a minimum.

(Personally I got a 80cf cylinder but I am using scba...I dont think I could get one smaller for the grade of gas)
