Hello,

Manuals on dying by helium recommend the use of a homemade exit bag (e.g., in Jessica Dueber's manual, see [1]).

Regardless of how you position yourself physically when committing suicide, it seems to me that there is a risk that the tube or the exit bag will somehow slip off when you lose consciousness and your muscles become limp.

The procedure recommended by Dueber of sitting in an ear chair, which is supposed to prevent slipping sideways, does not seem very reliable to me.


I came across an interesting variation in the press coverage:

A man built something for his parents that connects an oxygen mask to a helium bottle [2]. So, instead of wearing an exit bag, an oxygen mask is worn for suicide. Instead of oxygen, however, it supplies the user with helium. If the connection between the oxygen cylinder and the helium cylinder is well made, slipping of the helium supply, interruption of the helium supply or even the entry of room air into the oxygen mask should be almost certainly prevented.

Another advantage should be that one can die while lying down.


This raises the question of how such a connection between the oxygen mask and the helium cylinder can be made stable and reliable. The magazine article I found [2] only mentions something ominous about a "device". There is only a vague reference to a "device" that connects the oxygen mask and helium cylinder to each other.


I would assume a pressure of 14.5 PSI.

I wonder if it would be sufficient to simply connect the two hoses with (thick) aluminum tape. In addition to the relatively thin aluminum tape, which tears easily, there is also the slightly thicker (e.g., aluminium of Tesa brand), which in my experience is quite stable [3].

What do you think of my idea with the aluminum tape, or does anyone have a better idea?

The connection has to be almost 100% reliable.


Best regards,
Suizident

2 hoses? You mean one from tank and one from mask? Just use a double ended hose "barb" and clamps to connect the 2 hoses.
