A couple of points.
I'm writing this while I'm reading a certain document.
I wouldn't want to rely on an 'exit bag'. Filling a space with pure helium, no oxygen should be lethal.
I guess there is the common denominator of agony by oxygen deprivation (nausea, headaches, the works) ? Anything in particular ?
Then the question of purity. 100 % is good. But how 'low can you go' ? I have seen a source of balloon helium, a tank with 20 litres. I see technical data including approx. nominal contents 3.62 m3 (squared metres) but no purity. Looking at other sources, they tend to list a purity above 99 % or 100 %. Can one rely on that ? Too much oxygen=life.
Then the quantity. If one wanted to fill a space larger than a 'bag' that would require many cylinders, right ?
At first glance this doesn't look like a superior method. Some kind of standard oxygen deprivation, same as nitrogen ? Comments ?
