This is a video demonstrating the effects of sparks and flames on various material in a Vitaeris 320 Portable Hyperbaric Chamber with a Sequal 10 Oxygen concentrator delivering 10 lpm of O2 into the chamber. The portable hbot chamber is pressurized to 4.2psi during the test.

That is stupid... what would you have done if you would have had a flash fire... how did the plastic burning smell, and noxious gasses? Mmmmmm... Horses are smarter... a lot smarter
I did the math as suggested but got skewed results because no person has 60 breaths each second. Did you pluck this number out of the air? better read some good books on the subject or work in a clinic. No o ne makes the claim that the bags are not safe. Just not to any US codes. And not efficient. Better treat children at a fraction of a cost at home using a "Hudson" mask or nasal-prongs. now THAT is real science. "Show me the science"
This is not great at all. Pathetic in that the experimenters are assuming that O2 is an explosive gas. It is not. They would get the same results in a "hard" chamber on 100% oxygen chamber, no matter what pressure. The real question is "Why?" Why go to the trouble of zipping you child in a bag, paying dollars for it, when you get the same percentage results from sitting in a room breathing Oxygen from a Hudson mask? And at a fraction of the cost with higher safety for all concerned.
Same as 100%O2... wait, the test has been planned. :)
As for breathing O2 from a mask in a room... an adult lung is 0.5 liters and a breath is taken in less than a second. That means the lung fills at a rate of 120 LPM. if 10LPM of that is 100%O2 by mask the remaining 110 LPM is 21%O2. Do the math and you will find that the lung will only have 27.6% O2.
In a 1.3 environment that is augmented further by the pressure. There is also the influence of the autoregulatory response.
