Argon is also extremely narcotic, does it enter your mask ? >The main advantage would probably be that the gas liquefies at high pressures, and >thereby reducing the size of the inflation gas tank (a 0.5 liter tank to 200 bars would >be adequate... => roughly 200 liters of gas). If you were to use it liquified would it vaporize fast enough to provide the needed volume to inflate the suit quickly if need be ? What will you think when you turn to a possition where the liquid N2O is below the gas in the tank and comes out of the valve and into the suit? Brrrrrrr ! What will liquid N2O do to your inflation hose ? (If it britilizes and breaks I guess that 38 degree water might feel pretty good after a blast of liquid N2O on the chest) When the gas enters the suit it will probably be just above the temperature of vaporization (gasification?). As cold as it can be and still be a gas, or just above the temperature at which it turns to a liquid ! ! ! ! Brrrrrrr ! Stick with Argon !
