SF6 is really harmful for the ozone layer. It has a global warming potential of 23900 times that of CO2. Since the start of 2016 it has been banned for all applications except electrical switch gear and they are handling it so poorly. WTF

Idk why he needed gloves while handling the liquid nitrogen because the Leidenfrost effect creates a layer of gas in between so the nitrogen never touches your skin...
