Inert Gas Exit bag vs Mask

[emma99]

Okay so Im looking to try to determine weather or not a bag is more useful than a scuba/scba mask for using the inert gas method.

After first coming to this website i was lead to believe that a mask would be more efficient than a bag.
I know that the Slovak guy used a scuba mask, and that Gas Monkey had intended on using a SCBA Mask.

However after what happened in the state of Alabama with the horrible execution of Kenneth Eugene Smith
Philip Nitschke released a podcast called "What I wish I'd Toold Kenny"

Where he goes into detail about the risks of using a mask, and explains why the inert gas method was designed to be used with a bag.

'What I wish I'd told Kenny' (before his Nitrogen execution) - The Peaceful Pill Handbook

Alabama death row inmate, Kenny Smith, made history in a way that he never wanted. He became the first prisoner in the US to be executed using a method known as nitrogen hypoxia. Kenny Smith died from a lack of oxygen to his brain. Eye-witness accounts of his death show a man experiencing a...

I am thinking about it too. could you please clarify to me the following question :
How should the plastic tube should be attached to the bag? Should it pass through the bag, and in this case, where it enters the bag, there may be a nitrogen leak or air flow, or should the entry point be well sealed with tape? please see attached pic from book. i am not sure about my understanding of this point.

This is why I hate this method. Everybody claims it's easy and yet nobody knows how to do it.

Every photo I've seen here of an Exit Bag shows the tube going inside the bag through the neck opening, no holes needed. Then you tape the tube to the inside of the bag to keep the tube from falling out.

I made an Exit Bag with the tube routed through the neck as a test and it worked when I inflated it with an air pump.

A typical mask will not be airtight enough. You do not want there to be oxygen in there or leaking in. Scuba masks might work (I do not know), but do not use a mask that is used for providing oxygen to people in respiratory distress, or other medical settings.

The supply tube needs to be inside the bag, from the entrance. It's best not to cut a hole, as that's one more way that oxygen can leak in. That said, I think PPH exaggerates the sort of precision that is needed.
