Nitrogen gas with EEBD hood Guide (Inert gas Method)

[mando]

I think @FreeSpirit1Love has one too. He said above that he does.

No he has a MSA hood

That is interesting. The orange hood LOOKS LIKE it has an exhaust valve on it, or at least the space to accomodate one. Have you carefully prised the side of it to see if it is jammed?? That sounds daft but with those brands you never know.
Thanks Ztem for the mention. And yep, the yellow hoods work fine, there are fitting issues for those of us with smaller heads but before anyone gets their knickers in a knot, the mouth/nose fitting sits where it shoud and does what it is supposed to.
Why anyone would buy a 2nd hand one when theyre $0 + freight is beyond me.
The crimping tool etc is unnecessary, I worked with high pressure air tools for decades and a double ended brass joiner with what we call 'ear-clamps' on each join, or the butterfly hose clamps will suffice. Best wishes to all.

Indeed, i call it a placeholder, but there are no moving parts at all.
just solid plastic.

Dumb question: If you don't have/need an extension hose do you need an adapter? My thing seems to fit sorta but it doesn't seem very secure :(

If the hose is long enough, and you know the type of connector thread used, you can get an adapter.

I found the correct thread type for my EEBD hose connector, which turned out to be a M10 thread.
So I bought the correct adapter which worked, but I ended up modifying the hose anyway, because I had doubts about the original connector, which had a small opening compared to the usual hose connectors.

My post here has photos of the original EEBD connector.

Thank you! I am incompetent so need a little more direction if you're able to eyeball it.

These are the pieces not put together (flowmeter on top, eebd hood on the bottom)

When they fit together they screw a couple times but you can see it doesn't go all the way

It doesn't look like an M10 is the way to go right? any idea? If it helps I am in the US.

The thread types don't match then.

But your EEBD hose connector does not seem to have any threads?

I'm seeing two hoses.

What hose is the above one with the brass connector?

And the bottom hose?

You should not automatically assume that your EEBD hose connector is the same as mine.
It probably isn't.

 

[DyingToDie123]

Bear with my lack of technical understanding here haha

But your EEBD hose connector does not seem to have any threads?

If threads are the little lines that make it possible to screw on (my understanding from google search) then no it doesn't appear to have any.

What hose is the above one with the brass connector?

I feel dumb but is CGA-580 a hose type? I can DM you the Amazon link if it's helpful, not sure if I'm allowed to post it here. It came with a couple extra pieces that I haven't figured out what they're for yet, but none of them seem to fit onto this bit.

And the bottom hose?

The product description just says "hose" lol. There is a plastic bit and filter that isn't on the one in OP's which is making me confused as to how I would use a crimper, but maybe I could just cut it off?

You can PM if you want.

Does the bottom hose belong to the EEBD hood, or is it a hose you bought yourself intending to create an extension hose?

 

[DyingToDie123]

It belongs to the EEBD hood.

 

[ClownWorld2023]

It belongs to the EEBD hood.

The above hose with the brass connector is a rubber hose.

Did it come as part of the regulator, or did you buy it yourself to use as an extension hose?


Anyway I need to go to sleep now.

I'll answer your questions later.

It would help if you took better photos of both hoses, and the regulator.
If you don't feel comfortable posting them here, you can just PM me.

I miss this guy how sad hes gone now :(

Came with the regulator

Good night and thank you a bunch!!

Where are you guys finding these EEBD hoods, especially in Europe? I was able to find a single one with a tube on the entire internet from a shady open-box indian seller on ebay, and that was the type that is not recommended (drager). The rest are super-expensive kits (4-10x the price) that include the air cylinder that I do not want.

I wouldnt mind a SCBA but that is even more complex as I cant just see a mask with a tube and be sure it will work. Most are just filter masks or cylinder straps for your back.

So im willing to settle for an EEBD hood… if I could find one!

I got mine off a world-famous auction/bidding website. Mine was a branded one, so cost me about €200 including postage. Google ELSA rescue hood (ELSA stands for emergency life support apparatus) - it should bring up the hood type I bought.
Several people on the inert gas megathread bought theirs off Alibaba, ~$20 in some cases.

Hello, I am a new member so apologies if my questions are dumb:
one thing I can't understand is how to fit a regulator to the specific cylinder + which "hose" should be connected to the cylinder and go into the bag?

Anyone has images?

If it is an oxygen tube you're talking about (oxygen tube=hose? unlike in the pictures above) than it is hard to find an oxygen tube that delivers 15Lpm... I only found ones that deliver up to 10.

Plus, if I do find one oxygen tube, then how is the oxygen tube connected to the cylinder??? I am talking about bag method, not mask.

I've read about using a hose clamp here, but I am not sure about how to connect a hose clamp to an oxygen tube???
Can anyone please explain this part? I will be very grateful... that is what I'm mostly have trouble with comprehending.

In the Max Dog brewery video it looked easy to connect the plastic tube to the regulator but they are no longer active from what I'm seeing...

How important is the position of being seated or lying down if using an eebd hood method,I had thought of using my car seat but a small pop up tent may have to be an option now for privacy, making getting a chair inside it difficult,near impossible only really able to prop myself up abit inside the tent and the nitrogen bottle would also be lying flat,not sure how this will affect the method, convulsions possible etc or flow of gas , disturbing the hood or even not filling it properly.any thoughts?

The US department of labor states a compressed cylinder shall not be used in a horizontal position and may only be transported or in short periods lay in a horizontal position. You wouldn't want to upset them would you?

On a more serious note it should be all right having it horizontal regardless what the OSHA says, their main concern are gases that becomes liquid when being compressed. These gases are not suitable horizontal since it relies on being vertical to be release gas, luckily nitrogen is not one of them. Another concern is since the cylinder is round it can easily roll away from you possible damage your connection, that is one of their arguments for not using it horizontal.

Regarding use of compressed gas cylinders while in a horizontal position | Occupational Safety and Health Administration

www.osha.gov

Regarding your tent idea I would personally use the car instead, putting a chair inside a tent sounds quite flimsy and I can see you easily falling down knocking down equipment failing your ctb.

 

[needout]

The chair inside the tent isn't really possible as said but lying down is but would that affect the method using a eebd hood and nitrogen,I'm thinking since I'm lying down I can't really fall over or around,Im not sure on how much convulsions may take place

Hi, I think using an eebd hood and nitrogen gas is my preferred method. I'm wondering about the regulator/flowmeter. It seems like Vizzy used an argon regulator but still talked about using nitrogen gas. The only nitrogen regulator I could find is $400. if I use an argon regulator instead, does the flow rate change from the standard 15 lpm for nitrogen?

Argon flowmeter works with nitrogen, but since argon is an heavier gas there will be some miscalculations on the meter. All trough not much but depending how much inert gas you have at hand it may be of importance, here is a conversation supplied by Tearsinrain

- 12.5LPM on argon flowmeter gives ~15litres LPM nitrogen flow
- 15LPM on argon flowmeter gives ~ 18LPM nitrogen flow
- 20 LPM on argon flowmeter gives ~ 24 LPM nitrogen flow

Thanks for replying. If I get an 80 cu ft (~2265 liters), then I think I'll be ok. Does that sound about right? I also plan to test it out using a dummy head and an O2 meter.

That would certainly be enough, almost 2 hours with a flow of 20/lpm. This will allow testing the setup as you suggest and several attempts if you were to abort. Looks promising.

Thanks for your help and for answering my questions. I'm not wanting to ctb soon by the way. Just wanna have it as a exit plan in case my diseases progress. You've helped me have some peace of mind about all of this

I'm glad to be of service! A fully tested and functional way to ctb can be a comforting thought. I'm sorry about your condition, I hope you will somehow recover.

Thank you! It really is. I literally have a condition that can make my skin feel like it's on fire.

I wish the best for you

That's way more than enough, after just one minute with no Oxygen, brain cells begin to die, after three minutes permanemt brain damage, after five minutes, survival almost impossible, and after ten minutes, death is certain, and you have a whopping 2 hours worth at 20 LPM---My amount is somewhat similar, 1600 PSI at 3500 Liters is about the same amount as yours--So, just 10 minutes and that's it, oblivion---Make sure you test it out, using an O2 meter with the dummy head, or on yourself like I did--In my tests, with the EEBD hood on, after about 4 or 5 deep breaths, my Oxygen(O2 meter on my finger) dropped from 98 to 46(ten second delay), so I imagine it would have dropped to zero after another 30 seconds, and at that point, 5 to 10 minutes later and you're gone

 

[goldenbananagirl]

Does anyone know if it's better for the nitrogen to be food grade or industrial grade? I've been calling places and they ask which kind I want.

Thank you, I plan on testing with the O2 meter. I don't think I want to risk testing with the hood on. It'll be good to have peace of mind tho

For his method , is it better to have th hood that goes past the neck or does face mask like this suffice ?

1. Also, is this regulator gonna work ? It was only 23$ which is concerning. Yes i understand the flow rate calculations to adjust for between argon and nitrogen , just concerned this thing is a piece of shit since so cheap
