I was doing a small project about compressed air and found some death relating stories about compressed air intake. apparently if you take in enough it freezes the inside of your body, whether upright or upside down. But what happens if you go about just spraying it and letting it go free into air without in-taking it directly. Upside down you see the liquid come out along with the compressed air. is that harmful in anyway or would it just dissipate into thin air?
If you release it directly to the atmosphere, it will be warmed by the ambient air and not be a problem. It can only be a problem is it is at very high pressure and is then released to atmospheric pressure in a small enclosed space where you are breathing. Then you might experience some frost bite but remember people breath air all the time in very cold climates where the temperature is well below freezing.
