Method In what way can the nitrogen method realistically fail?

[Rabitfever]

Given that I'm able to setup the "nitrogen + regulator + mask" method, what ways can this method fail?

Leaving aside common reasons like impure nitrogen, leakages, pulling mask off accidentally, etc

 

[Greenberg]

Reasons for failure:

• Not employing a flowmeter
• Poorly constructed/secured mask
• Running out of nitrogen

What are the consequences of these failure possibilities? Do you just wake up unscathed after a while? Or do you go into a vegetative state?

Brain damage.
Probability is proportional to improper setup and equipment.

Are there any records of people removing the mask/bag while unconscious?

I will use a chair with arms so I can slip my arms into loose cords (wrapped around the arms of the chair) at the last minute.. to prevent myself from grabbing the bag and letting the nitrogen out by mistake..

I have a SCBA mask with demand valve and regulator, so as long as I set it up correctly and the nitrogen cylinder I have is sufficiently pure and properly filled, the only thing that will prevent me from success is someone interrupting me, which is frightening to think about.

At least there is some comfort knowing that it is usually a very quick process (about 7-13 minutes) but there have been outliers who have taken up to 40 minutes. Those were all traditional exit bag set-ups though, and I think that the excess time was probably due to a bag that was too loose.

Why take the chance??

@Rabitfever using a mask

@Mors you aren't supposed to have the bag too tight though or you'll get CO buildup. Got to leave it about two fingers width loose around the neck. I think mask is more risky of failure.

@Greenberg you do have to leave some space open with the bag at your neck correct? You can't have it all the way tight or Co buildup will occur correct?

Reasons for failure:

• Not employing a flowmeter
• Poorly constructed/secured mask
• Running out of nitrogen

@Greenberg a 20cu tank was all that was recommended, shouldn't that be enough to not run out if the tank is full?

Right, I am not implying that the bag is supposed to be flush with the neck but I believe that if it's too loose it can definitely pose a problem and prolong death, since a higher percentage of oxygen would enter the system.

I think mask is more risky of failure.

The kit I have includes a SCBA mask with demand valve and regulator, so gas is only let into the system when I breathe and the pressure and flow are automatically adjusted. I have tried the mask on without the demand valve and thus no gas flowing and can confirm that the mask is completely airtight from the environment, ensuring maximum lethality once the gas is on and the demand valve activated.

And I've come to understand that using a SCBA mask with a demand valve is not only quicker, it also requires significantly less gas because of the efficiency of the mask and integrated demand valve. However, I had already purchased a 40 cubic foot cylinder before I discovered the kit I eventually purchased online.

I suppose it worked out okay. I have ample gas for a trial run to test how quickly I become unconscious and experience how it feels since there's always some variability from person to person.

@Mors how does the SBCA mask prevent CO2 buildup? How does it filter it out? Have you heard of the rebreather?

I assumed there was something like a filter or release valve that allowed exhaled carbon dioxide to escape the system. This was confirmed by the seller via email:

The SCBA mask has an integrated one-way valve for CO2 to be expelled into the surrounding atmosphere.
