Method Exit bag and inert gas megathread

[rationaldespair]

Hi, I'm new in this forum. I can see that there has been extensive discussion of the potential use of exit bag and inert gas. Has there been any discussion about using one of those 2.2 L disposable nitrogen? I know the ideal volume to use would be 400 L but they're quite hard to obtain where I live without a car. The 2.2 L cylinder contains 240 L of pure nitrogen - would it be viable for the purpose of CTB to use two of these cylinders simultaneously if I control the flow of each cylinder to 8 L per minute? Thanks!

For Scuba, I'm wondering about the ports. I'm wondering which ports this part should be connected to? Please.

Are the Chinese EEBD hoods reliable for our needs?
I already have 2 but I'm having doubts reading various posts.
I'm also confused if the ones I have with exhale valve are preferred or ones without?
Has anyone taped the exhale valve shut so that co2 goes out the bottom like an exit bag?

Is there any tutorial about how to connect oxygen tubing to the tank? In the PPH it talks about everything you need materials wise, but doesn't say how to do this as far as I can see. Would be great if there was a tutorial with images on how to put all the components together, or a video like the one somebody recently sent here of how to make the bag.

I've been looking at this, and the problem I'm hitting is that they have a max flow rate of 6 l/m when you look at buying regulators for the disposable cylinders. I'm now contemplating a setup with 3 so that each can be set to 5 l/m but I don't like the 'more moving parts' aspect.

According to a discussion by TiredHorse and another by Fightingsioux, it is recommended to use a 20 cubic feet nitrogen cylinder. Fightingsioux mentions that 20 cubic feet should be more than sufficient.

I am based in the UK and currently have a 2-litre compressed nitrogen cylinder, which I purchased from Adams Gas following the below guidance which I read from the Peaceful Pill Handbook:

PPH
"In the UK, full 2-litre cylinders containing approximately 350 litres of compressed nitrogen are available for home delivery to UK addresses from Adams Gas."

Based on my calculations, 350 litres is roughly equivalent to 12.36 cubic feet, which is less than the 20 cubic feet recommended by TiredHorse and Fightingsioux.

Do PPH's specifications seem accurate? Were the estimates by TiredHorse and Fightingsioux possibly overly cautious?

Any insights or feedback would be greatly appreciated.

I attempted two times and failed. Is a helium tank for balloons enough? And also since you have to press the black nozzle to let the helium out, how exactly do you manage to do that?

I wanna know this too. I have everything else ready but having a very hard time getting Nitrogen. Can get as many tanks of Helium as I want though.

I am using "AiRise Small Portable Helium Tank, Blue, for Birthday/New Year's Eve/Graduation/Baby Shower/Wedding/Halloween" from Canadian Tire and because its says its 100% Helium there HAS TO BE a certain number of tanks after which it works right?
