Inert gas storage and purity

[suicideprepper]

I'm what I call a suicide prepper. In case of a nuclear war or climate collapse or anything of that sort, I'd like to have a trustworthy method of painlessly leaving the world before it forcefully kicks me out.

I'm in a country where acquiring a shotgun, which would be my first choice, is extremely difficult. Fentanyl, Nembutal etc are not stable enough for the time window I'm looking at, especially not at the temperatures we're used to reaching here. Sodium Nitrite is good, but the antiemetics needed are can't survive that long (and I'm worried I won't be able to buy antiemetics when the time comes).

I'm left with the Inert Gas method. However, storage of these is complicated. I hear that leaks are essentially inevitable, and that a compressed cylinder will lose its purity over time as a result.

I'd like to know the extent to which that is true and, if it is, I'd like to know how bad an idea it is to try to kill oneself using subpar Helium, Nitrogen or Argon.

Thank you so much,
suicideprepper

There is no loss of purity, 2.5 years after getting my huge Nitrogen Tank, my Oxygen level divebombed to 40 after just 5 or 6 breaths at 25 LPM(10 second delay), but there is some slow leaking from the tank, the PSI dropped from 2200 to 1600 after 2 years, but in the last year, it has stabilized at 1600

You can pay the cylinder and just refull it even year

@outrider567

How big is your nitrogen tank; and, why does a PSI decrease indicate a leak?

The only way for the pressure in the tank to drop is either from manually use/releasing it OR it leaking out on its own.

Nitrogen tanks always leak eventually, they are under pressure, the PSI, pressure was originally 2100, but after more than three years, its down to 1600--However my tank is enormous, 3500 liters, 125 cu ft, 69 lbs

Then how can you assert there is no purity loss?

Pressure is not purity.
Pressure indicates volume of gas.

As far as I know inert gas doesn't go bad or lose concentration of the gas unless mixed with another gas.
I'm not an expert though

Let me quote an answer for you from Google: 'Nitrogen is highly stable and the purity will remain the same INDEFINTELY for many years

You are correct! as per Google

Then how can you assert there is no purity loss?

Here's another quote about Nitrogen from Google: 'Even at 95% Nitrogen concentration and 5% Oxygen, human beings would pass out quickly and die soon thereafter'

I have been searching quite a bit for examples of N2(or any inert gas) quantity remaining (pressure loss) after a few years in storage and can't seem to find any info.
Have you had any experience with this?.

Hi Smith, yep....mine has been fine coming up 2 years.

Hey,I still have the plastic wrapper on the cylinder outlet.
I have been wondering if I should hook up the regulator to check pressure from time to time.I have heard this is quite inaccurate though?.
I have never hooked up a regulator-cylinder, but I don't forsee that being difficult.

 

[k1w1]

It would be easy for a child !!
Nope, dont do that, or.... do it once for practise. while they are refilled cylinders, and have been used many times, the reg is not and it has soft brass insert which helps it knit; while you can remedy any small leaks with plumbers tape....why tempt fate.
Nice to hear from you, which mask did you end up going with?

 

[sm1the]

Still have the 'ELSA'.
Isn't plumbers tape not recommended for cylinder to regulator connections?(because sealing is done through rubber washer between this connection).
That's what I have read anyway .
Ligature seems like the most peaceful accessible method available (at least to me), I'm actually considering this too.
