Method Exit bag and inert gas megathread

[k1w1]

Dear members of the Nitrogen Master Race. The time for a dry assembly of my components is upon me & I am hoping for some input from Gas Monkey, Ztem, Anonanon et all.
The regulator came with a screw-on barb fitting, unlike others I have seen this allows the barb to seat within a concave seat. Along with it came an o-ring. Would my colleagues here have a look at the images & chime in if the O-ring is in the correct place to effect a seal belween the regulator & barb. Thanks guys.

So I finally managed to test the purity of my N2 cilinder which should have a quality of 4.6 (->99,996%) according the supplier.
I used the CY-12C (it's mentioned many times and an oxygen meter doesn't kill, so I guess it's allowed) for testing, but it doesn't seem accurate.
I followed the procedure from PPeH two times and the first time it read 0,8% and the second time 0,5%. It also fluctuates heavily when you use the balloon to pump normal air around. I don't have much reason to not trust the source of the N2 because they sell in almost every city in 1-2 stores. So I'm either doing something wrong or the meter doesn't work well. @Das Nichts: how did it work out for you?

• Did you calibrate on 50% or 100% level ?
• Did you wait for 3 - 5 minutes for the oxygen meter to stabilize ?
• Did you calibrate with ball pump and hose attached ?

You think this one is fine for o2 testing? https://www.amazon.de/gp/aw/d/B0BGXP6CS8?ref=ppx_pt2_mob_b_prod_imag

• Did you calibrate on 50% or 100% level ?

The version I have has strangely enough 5%, 25%, 100%. So I calibrated at 25%.

• I squeezed the ball pump for maybe 10 times
• Waited at least 3 minutes
• Calibrated to 21%
• Connected the oxygen hose to the flow restrictor on the N2 bottle
• Switched to 5%
• Opened it and waited a few minutes until the value looked stable

I did also a second test without using nitrogen:

• I squeezed the ball pump for maybe 10 times
• Waited at least 3 minutes
• Calibrated to 21%
• Squeezed again like 10 times
• Waited again 5 minutes
• And now it says 21,7% in the same normal air?!

So it seems that it has to be calibrated after every flow trough the meter.

The biggest problem is the manual which only contains Chinese. So I don't know exactly when to use the pump. I'm considering to order the O2Box from forensics detectors, because this honestly makes me a little bit nervous. I tried yesterday even a third time and then it even didn't go below 1%.

Looks about right. To be fair, I did not my testing some months ago so I'll have to redo it and make some notes.

@GasMonkey was suggesting that unit might move insensitive as opposed to the cy-12c but there is no evidence to back this up or contradict it.

I'm not knowledgeable enough about the topic and it's also not my biggest concern.
Somebody should probably invest the time and do propere reserach about resulation and all the stuff that matters with that.

Personal opinion: I prefer a device that measures a single property that I'm interested in with reasonable precision and not 3 additional different things.
I also don't use 7in1 shower gels 😂

Yes, I see it has some bad reviews too.

The reviews look good. I'm not sure if you can connect the oxygen hose to it.

 

[Das Nichts]

Nah. You need to put it in a bag and fill it with gas. Something I also do not prefer.

FWIW: I found a video where a guy used a much more precise device to validate
the CY-12C measurements.

Sorry for interrupting the CO method discussion.. but I want to share it in this thread as well.
I did some further research about suicide with CO2 and I think you can CTB with it.
At i'ts best, you should get unconscious before you can recognize the CO2 gas in a small room / in the car. Therefore, I will show you 3 different cases I could find about the aftermath of the gas CO2 .


I Case
A family of 4 got accidentally unconscious because of the leaking CO2 bottle for Aquariums inside their car.

​

The translation of the article in English

KRIENS: Family of four almost suffocated in the Sonnenberg tunnel After Saturday shopping, a family of four is driving on the A2 motorway when carbon dioxide suddenly fills the interior of the car. Thanks to an attentive motorist, they survived.​

​

The incident occurred at noon on Saturday, at 11.45 a.m., on the A2 motorway in Kriens. A family of four was on their way home after shopping. Shortly before the Sonnenberg tunnel entrance, the CO2 gas cylinder for the aquarium leaked after a defect, according to the Lucerne police.​

​

The gas quickly poured out and filled the interior of the vehicle. In the middle of the tunnel, the car slowed down more and more, came to a standstill and then rolled backwards into the fast lane. For several minutes, following road users drove past the family until finally someone stopped and inquired about the occupants.​

​

The entire family sat unconscious in the car. After the doors were opened, they gradually recovered. Two ambulances took the family to the hospital. They were unharmed. However, the family was very lucky in misfortune: According to forensic medicine, there was an extremely high risk of suffocation for the unconscious.​

And this video shows the situatioin. The car was standing, the people were unconscious inside until someone opened the doors after approximentally 4 minutes. No one of them was in panic or tried to open the while being in panic. They where just unconscious.




II Case
A family died. The mom and the two kids got murdered by the father through suffocation and then he commited suicide. This article shows what the newspaper wrote. But when you read the forensic case report about this case you can read that the family father used a 500g CO2 bottle for Aquariums, inhalation masks and a bag plus rope for himself - to murder this family and commit suicide after.


III Case
The last case is about suicide with baking soda and citirc acid.

 

[NoFutureAnymore]

Nah. You need to put it in a bag and fill it with gas. Something I also do not prefer.

You can see something which looks like an oxygen hose connected to it in the video on amazon at 0:11. It looks like you can put a cap on it with a connection for a hose.

FWIW: I found a video where a guy used a much more precise device to validate
the CY-12C measurements.

It also shows a difference of 1.8% with the more professional device.

 

[winterparty]

Yes, I see it has some bad reviews too.

The reviews look good. I'm not sure if you can connect the oxygen hose to it.

So I wanted to put the hood on a dummy head and measure it inside the hood. https://www.amazon.de/gp/aw/d/B0BGXP6CS8?ref=ppx_pt2_mob_b_prod_imag Do you think that is accurate enough?

 

[Das Nichts]

Alright, back with testing results. These results are from a 3.0 Nitrogen cylinder (99,9%).
I think this is fine.



Procedure

• Attach hose and ball
• Squeeze a few times
• Wait some time
• use the calibration dial to set 21%
• wait some more
• attach oxygen tubing from the cylinder
• if it's off calibrate again to 21%
• turn gas up (1 lpm)
• wait some more

I also found a manual for the device:

I can't calibrate it to 21% anymore. It's stuck on 18-19% and I can only calibrate down. So I guess it's a faulty meter. I'm going to try to contact the supplier, thank you for your help!

Hello. Can someone explain in more detail what kind of unconciousness occurs after a minute of oxygen deprivation? Is there the possibility to wake someone up within the 5~ 10 minutes with a pain stimulus or something? If you punch someone in the face for example. How long until something like this isn't possible anymore?

It's really important to know this. I have all important parts now. I'm in a lot of pain so I want to ctb.

After 10 minutes you need life support measures. Below 10 minutes I think it's possible.

Im not an expert on hypoxia but I don't think you can simply wake up from a prolonged oxygen-derpieved state, just like how you cant just punch someone out of a coma. Hypoia indcued unconsciousness is different than any other forms of unconsciousess like sleep or being drunk as you're literally cutting of oxygen supply to the brain which will most likely cease any/all neural-network signals including the ones that detect pain. That's why the first step to treating hypoxia is getting the patient out of the low-oxygen atomposhere and medically supplying them with oxygen. If the damage is too much, revovery is vitually imposbbile

Never found any definitive information myself. Id say everything above 5 minutes is probably impossible.

But do you know whether it's impossible to detect pain from the moment on you become unconcious or is it like @Das Nichts said and it's impossible after approximately five minutes to detect pain/wake up from it.

Im not sure why you're so concerned about pain, inert gas aphyxiation is quick & completely painless. It doesnt matter if your Thanos himself, you wont wake up unless someone immidiately finds & rescues you. Death via hypoxia will occur in less than 10 mins if you do everything right.

I thought you where talking about intervention from a third party. I did a blackout test with my gear and fell into a cabinet because I was sitting and that's the reason I still can write here. If you do this in your bed or fixated to a chair when you unconscious you are gone.

 

[Rinmo]

is a small canister of nitrogen enough? it says 6.7 liters/1m3 2000 psi QF-2G1
and does flowmeter needed? i can't find n2 regulator that has flowmeter attached that's still within my budget.

What's your method ? Exit bag ?

Gas volume should suffice. The purity needs to be 99,8 minimum.

You need a regulator with a flowmeter otherwise you can't set lpm. If your in the us/CA you can get a reg with schf and convert that to lpm.

6.7L * 137.89 bar (2000 psi = 137.89 bar) = ~924L of uncompressed gas. This is plenty. A flowmeter is needed if your setup calls for it. For example, SCUBA/SCBA does not require one (they instead require a pressure regulator since there is a demand valve), but an exit bag or constant flow hood does.

Exit Bag: Sit upright in a chair, but the headrest makes a pressure to the exit bag from behind and closes the gap in the neck?
The same in a bed, upright with pillows.

I would go with the chair The neck thing does not make any sense to me. Just make sure you have a gap where CO2, can escape.
