Help Inert gas method (nitrogen or helium)

[heavenplzhelp77]

I need help with information about the inert gas method i already saw a post that recommended too much of a unnecessary quantity of gas considering that if you breath pure helium or any other inert gas for five minutes or even less it'll be sufficient to be lethal so please does anyone know how much helium do you need to be lethal is 7 litters enough for one to breath it for 5 minutes?! Plz can anyone explain how do the quantities work (five minutes and a plastic bag should do the job right!)

When I looked into helium at 1st thought it be easy. But then discovered all the easily obtainable helium like helium tanks from party city and other places isn't pure enough. And obtaining helium pure enough is next to impossible. I don't know about nitrogen or other gasses. I know that i need to die. I gotta do something. Maybe combine methods. Some here have suggested.

Actually I have found helium that's pure enough so how much does one actually need? Would seven litters be enough?! Does it go for five minutes!

You'll need approximately 12-15 min of inert gas at minimum to successfully ctb, since that's the time it takes for the cells to completely die. Sure the bag may stuck in front of the mouth depriving you from oxygen that way, but I wouldn't count on it.

At the recommended flow rate (15/lpm) 225 liters of inert gas is the minimum amount of gas. But because of practice runs or other unforeseen weak points is recommended to at least double the gas to around 400 liters. I would personally say 1000 liters to be sure, the amount only becomes unnecessary large over 3000l maybe.

All inert gases are compressed to around 100-200 times of atmospheric pressure. The cylinder may start at 7 liters but compressed 200 times it equals to 1400 liters approximately. Most cylinders list their total volume or pressure, you have to look at these numbers to determine how big your cylinder is.

I don't understand how it works though your saying if it says 7 liters it's compressed and has more so let's say it's the type of cylinder for filling latex balloons and it fills 50 of them so how much is that worth?! Otherwise where the hell can you get a cylinder with a 1000 liters

I don't know but if you do it right it's supposed to be peaceful and painless
How do you know if it's pure enough. Some on here say don't believe what they tell you and apparently there's ways to measure purity

A "big" ballon cylinder as you're describing would equal approximately 380-400 liters, but you have to look at your particular cylinder to be sure. But be advised through ballon helium is often at a slightly less purity than the industrial standards. I've seen professional helium cylinders to be as low as 95% purity. Some U.S manufacturers have even as low as 80% purity in their cylinders!

The pph advice using an inert gas of at least 97% purity and others on the forum would argue at least 99.7% purity.

Most people here use nitrogen instead because it's cheaper and more easily obtained at a sufficiently high purity. For reference this is how a 1000 liter cylinder could look like.

I'm certain of the helium purity the only problem is the amount in it, i don't live in the west and in my country there's a local manufacturer that makes industrial grade helium so that part is guaranteed but if the amount in it isn't enough to be lethal what the hell am i to do lol i guess I'll just have to check if i can find nitrogen maybe else where

I'm having a feeling that you're not fully understanding what I'm trying to explain to you. How do you know the purity, is their any specifications on that particular cylinder your set on getting? What's the amount 7 liters? At what pressure?

Lol yeah ofcourse it's written on the cylinder there's a specific number and it says industrial grade helium 99.99% pure so yes like i said I'm absolutely aware concerning that part and it has 7 litters i don't know at what pressure I'll check and see

In that case you should probably be good, most pressurized cylinder are in the range of 120-200 bar. So if the vessel is 7 liters it gives us 840 liters in the lowest normal pressure (120 bar).
