Is anyone else doing the exit bag method?

[SomewhereAlongThe]

I don't see many people speak much about the exit bag method, though I think it's a really good one. I'm wondering if anyone else is doing the exit bag method like I am, no scuba, no hood, just the plain old exit bag.

What gas are you using? I want to use LPG but I'm not sure if a 9kg cylinder would be enough

I'm sure there are, but due to the immediacy of the means for many people (that is, no DIY involved), the hot thing seems to be SN, or hanging/tourniquet next. Of course SN also is becoming much harder to come by than before from what I've seen.

Are you satisfied with your materials? I know I tried haphazardly before properly researching the method (I have two left hands for anything DIY) and flunked it completely.

I am very much satisfied with my materials, my regulator is really good and solid, the tank I got is 1,533 litres of pure nitrogen, the turkey bags I'm using are strong and robust, none of my connections leak, so I am happy. Would you still give it a go after researching it?

I'm using Nitrogen and I have approximately 1,533 litres of it but I believe TiredHorse mentioned needing only 600 litres. Now I don't know how to convert a 9KG LPG tank so that the litres are accurate, but all I can say is you need approximately 600 litres of gas (non-liquified).

I would definitely give it a go. It was sheer ignorance that led me to attempt it with entirely subpar materials that would never have worked and nothing else, and now I am still considering it although with considerably more time to source the bottle, regulator, tubing (that part confuses me a little, as in, which tubing can be hooked properly to the regulator, but I've not checked the megathread properly yet), and then the bag, which now I know more about consisting of elastics + fastener (I guess like hoodie fasteners) + a suitably large airtight bag and some duct tape and scissors. (I think.)

It seems a very peaceful manner if you can assemble the components. Certainly it was for me, it just didn't lead to its conclusion.

As for the volume, my understanding (from memory) is you want a 15L/min flow to dislodge the CO2 (heavier than air) out the bag for 15 minutes (considered to bring death with this method), so 600L is actually more than strictly needed; but a) the methods is indicated for surefire effect and b) I might have gotten the numbers wrong offhandedly, plus c) having margin is good to fill the bag if you decide to abort the first time(s).

A lot of welding shops would source the tank for you. I suggest you buy a quality regulator, if it's expensive it's worth it. The tubing I got was PVC tubing https://www.amazon.ca/dp/B09L5KCC1X?ref=ppx_yo2ov_dt_b_fed_asin_title and you just gotta make sure the ID of the hose matches the nipple attached to the regulator. The hose should be a good length, mine was 5ft but you may need shorter or longer, ideally not going over 6 ft. I'm confused with what you're doing with the bag, are you duct taping it shut, or are you fastening it with the elastic and toggle?

I'm planning exit bag with Nitrogen in my car at night. I've got 660 Liters of Nitrogen and an exit bag made of an oven bag. No leaks in my system. Although I've got everything planned, I'm still afraid of failure.

Yes, upon looking properly I found Argon, which to my understanding works the same albeit being heavier than nitrogen as a gas.
I think I'll buy the regulator from the same shop, no reason not to. At 52€, it seems not as expensive as some of the oxygen regulators I saw, but not cheap either.

As for the bag, the idea is:
1) Lay bag flat.
2) Roll over about an inch of the opening outwards all around the bag, tape it against the surface. This creates a small hem.
3) Cut a small hole at the bottom of this opening, thread your elastic around
4) You now have your elastic running the circumference of the exit bag, coming in and out both of the hole you cut into your hem.
5) Use cord fastener onto it, like a hoodie cord closer. Which it is.
It's meant to emulate exactly that, as far as I can tell, but since I (foolishly) tried it with a mask before, I've yet to build it.
Looks like this in the PPH:


(The small rectangle is the attaching point tape for the tube, best I can tell).

Are you just using an elastic as is around the base of a turkey bag, or did you build your bag yourself?

It seems to me that we would want a pretty flexible hose that doesn't distort the flimsy bag. I'm thinking silicone, maybe 3/8" ID, it's readily available on Amazon. The hardware store vinyl tubing isn't very flexible, but that's what Tired Horse has.

Where can I buy the exit hood and what do I have to do with the gas and also where to get this

I am very much satisfied with my materials, my regulator is really good and solid, the tank I got is 1,533 litres of pure nitrogen, the turkey bags I'm using are strong and robust, none of my connections leak, so I am happy. Would you still give it a go after researching it?

Where can I buy those things please help me out , don't no what gas and where the hood
