Just found out my 40cf tank is at 150 bar ? Didn’t use much maybe they under filled?
How much gas is that in liters?

Normaly yep, depends on how many tests you wanna do tho.1. Should 5L 200 bar cylinder be enough for both test runs and the final run?
Yep.The 5L cylinder comes with a carrying handle, I guess one could just carry it by the handle?
Nope. It's not their business. :)Will it be a problem if someone sees me with it?
Welding.I guess a good cover story for buying nitrogen is infusing beer with it and for helium balloons
Strap it to a table.How do I secure it
With straps, but anyway only minor movements have been observed in studies of people CTBing with gas.4. How do I make sure I don’t fall from the armchair once I pass out and ruin my setup?
A 5L cylinder is small enough to be in a closet yeah.6. Is storing the cylinder in my closet a bad idea?
Argon is the worst inert gas option to CTB.I was also considering ordering some argon from Poland on eBay,
I think all cylinders are shipped in boxes, unless it's huge ones. Mine is 10L and it came on a box.the specific seller that I found ships the cylinders in boxes
Since you are a novice, start by reading the inert gas chapter in the PPeH and PPH Essentials.So the questions:
If you pre-fill it should be as fast as an ExitBag, which is about 3 breaths.Greenberg says it can take 3 to 6 minutes before passing out using the EEBD hood
If I'm not wrong it should have about 1000 litres of n2 inside which would take you over an hour to deplete at a rate of 15l/hMy N2 is at 150 bar? Instead of 200… doesn’t that mean there is less gas in my 40cf?
Yea I was just curious as to the 150 bar vs 200 bar and what that means in terms of gas quantityIf I'm not wrong it should have about 1000 litres of n2 inside which would take you over an hour to deplete at a rate of 15l/h

The 200bar one should be smaller since the gas is more compressed, it would also have more total gas for the same compressed water volume.Yea I was just curious as to the 150 bar vs 200 bar and what that means in terms of gas quantity
What do you think could be suitable for strapping both cylinders and myself?
I made a separate thread about the scuba method
I'm wondering if the pressured air G 5/8" thread adapter would work in this case, since they are made for 200 bar tanks?
I guess snorkel masks aren’t suitable for this purpose?
I'm confused, how am I supposed to continuously hold the button down once I lose consciousness? Am I missing something? This seems to be a crucial part, I'm sure there has to be an explanation.
Two fingers flat against the neck or perpendicular to the neck? Also, is regular size oxygen tubing okay or does it need a larger diameter?I seem to remember a "two finger" rule. It came either from the PPH, or Dr Philip Nitschke at Exit International.
You should be able to easily slip two fingers between your neck and the drawstring.
If you have trouble, then too tight.
If easy to slip three fingers, then too loose.
So the idea is the width of two fingers perpendicular to the neck.Two fingers flat against the neck or perpendicular to the neck? Also, is regular size oxygen tubing okay or does it need a larger diameter?
From Google:Can anyone tell me what do they mean by food grade nitrogen. Thanks
The cylinder should be well fastened, like to a heavy table or chair. You can strap yourself if you want but it isn't mandatory, neither SlovakGuy or Wunderkind strapped themselves.
SCUBA is a worse version of SCBA, there is no reason to use underwater gear when you can use land gear. If you want to CTB with a mask go for SCBA.
SCUBA is viable but has a series of inconveniences that I have talked about several times in other posts: most SCUBA demand valves run on Negative Pressure (so they have inhalation resistance), they don't create a Positive Pressure over ambient inside the mask (which is what creates a perfect seal in SCBA) so the seal is totally dependant on the mask->skin contact surface being airtight, and the very good mask+demand valve combos are very expensive.
Yes the air-to-nitrogen adapter works, it is the key component for SCBA/SCUBA setups.
Not for an on-demand setup.
Theorically they can be used on a constant flow setup, but with no demand valve and no reservoir bag, a very high flow rate would be needed to meet the demands of inhalation in the mask. The constant flow air purifiers with masks operate at a huge flow rate (over 60 LPM).
That's just a button for creating a constant flow, useful to pre-fill the mask with N₂. The rest of the time it pumps on demand.
From Google:
Food grade nitrogen is nitrogen with a purity and quality that meet US, European and other global standards for use with food and beverages. For example, the European Union defines food grade nitrogen as having a purity of 99% (less than 1% oxygen remaining).
Often used for brewing beer.
The low presence of oxygen is important to ctb.
Oh ok, l thought it was supposed to be 100% nitrogen. Sorry if l sound daft but this is all new to me 🙄From Google:

The argument linked suggests Argon would be a bad gas to push CO2 out of the bag on the basis of it being a heavier gas.Argon is the worst inert gas option to CTB.
I'm using an exit bag. Is it your understanding that upon inhaling gas post hyperventilation, loss of consciousness should be immediate? Rn I can induce loss of consciousness via hv, holding breath, and leaning head back...but I'm trying to figure what to anticipate. Should I be prepared after the first breath of gas to still need to breathe? I practiced before but was before I knew I needed to hv.The optimal flow rate was determined assuming a constant presence of CO₂, using a gas with a similar weight to Nitrogen (Air), so it should work without assuming a disappearance of CO₂.
Several members have reported "fails" (aborted attempts due to feeling suffocation/panic) using Argon, like the @jodes2 guy who was posting that Argon failed him in almost all new ExitBag/Argon threads, claiming that he did everything correctly. Whether we believe them or not is up to us. I tend to think that they did something wrong in the process, but the truth is that we only have strong evidence of 15 LPM working well for Nitrogen and Helium. The supposed issues of Argon should be solved by increasing the flow rate.
None of this affects me, since I'm not gonna use the bag but top-notch SCBA gear.
On this study the subjects blacked out in ~10 sec/3 breaths, congruent with @Diver_K_A's experience, @Wunderkind also blacked out during his tests without even noticing (testing his SCBA on his car). Dr Philip Nitschke also says that doing the process correctly (hyperventilation + full exhalation + deep breath of the inert gas) you should loss consciousness in a couple of breaths.loss of consciousness should be immediate?
Not True!Considering the bag doesn't contain any O2 you won't be able to produce CO2.
In the various resources I've read, I have seen that range mention. They never mentioned their exact definition of death.45 minutes? do you mean for every cell in the body to die? coz brain death happens within 5-10 minutes.
The end of the hose that connects to the mask has an ON and OFF button. How do I operate these/which buttons should I press when?
To check how much gas do you have.What do I need to use the pressure gauge on the regulator for?
That flow rate is irrelevant for SCBA, it doesn't work on constant flow.Everything I've read seems to only put importance 15 LPM
Should I use a different regulator/flow meter?
Damn. Can I buy something that can get the job done from a store rather than EM? I'm really trying to do this this weekend and can't wait for the shipping.Yep, you got the wrong regulator, it only has a flow port. You need the Pressure Flow Regulator (it's called like that because it has a pressure port and a flow port). Once you have that you will need to connect the SCBA demand valve to the pressure port with a wrench or 17mm spanner.

Also do you have discord?![]()
Once u press the demand valve. You leave it on ?The ON button engages the demand valve. Once it is engaged if you press it, it will create a constant flow of gas, which is perfect to pre-fill the mask with N₂ before you start breathing, 1 or 1.5 seconds should be enough to pre-fill the small volume inside the mask.
The OFF button stops the demand valve.

Once the setup is built and prepared, the process is:
1. Put the mask on.
2. Take a deep breath of air.
3. Insert the demand valve into the mask.
4. Pre-fill mask.
5. Exhale fully.
6. Take a deep breath of N₂.
7. Avoid the reincarnation trap.
Dude there HAS to be another regulator/flow meter that can be used! I have the tank, the mask with the hose. What do you suggest I do to get this done this weekend?Theorically you could connect the demand valve with an adapter to any pressure regulator (setting it up to supply the proper pressure) like Joarga did with an "industrial regulator". But that would have shipping time too since you would need to search for the regulator and adapter and order them. You made a big mistake by buying the wrong regulator on EM.
