It's pretty damn dangerous when there is a potential for a combined 90000 gallons of liquid hydrogen and oxygen in close proximity... the presence of concentrated oxygen GREATLY increases the explosive power of hydrogen and Artemis carries a LOT of both.
Compare on just the scale of a few milligrams: https://www.youtube.com/shorts/_RKdWYqgu3Y https://www.youtube.com/shorts/_RKdWYqgu3Y

- CrazyStat 4y agoIt's not "explode just because you looked at it funny" dangerous. Hydrogen is not hypergolic. With basic safety precautions (ventilation and making sure there are no ignition sources in the vicinity) I'd be happy to let my kids play with a tank full of hydrogen.
- gh02t 4y agoI mean you're right I'd rather deal with hydrogen than hydrazine or HF, but I'll respect your parenting choices from a safe distance.
- CrazyStat 4y agoHydrazine and HF can both kill you by skin contact or inhalation. The comparison isn't even close. The dangers of hydrogen are basically "oops I breathed so much hydrogen that I got no oxygen for several minutes" or "oops I accidentally ignited it", both of which are easily avoided by basic safety precautions. In the context of filling a high altitude balloon that started this thread, asphyxiation is easily avoided by doing it outside, and ignition sources can be eliminated with a little care. This kind of fear-mongering--"could explode just because you looked at it funny" etc.--is irresponsible.
