@fuggy @nosleep Yeah, no, air doesn't turn to liquid at that pressure/temperature.
Cans of "air duster" are almost always HFC-152a.
https://en.wikipedia.org/wiki/1,1-DifluoroethaneIt's extremely flammable and when burned creates hydrogen fluoride.
https://en.wikipedia.org/wiki/Hydrogen_fluorideThat shit is extremely toxic. You are in immediate danger (i.e. you could die) if there's only 30 ppm (parts per million) of hydrogen fluoride in the air.
The best part is you can inhale a lethal dose and not show any symptoms for several hours. Then a few hours later your lungs will start turning into liquid.
TL;DR: If you happen to ignite air duster inside you need to open doors/windows and GTFO as fast as you can.
