Is hauling liquid nitrogen considered cryo?

With whom?

 

Almost all gases can be liquid at the right temperature. Some commonly tankered cryogenic liquids are Helium, Carbon Dioxide (CO2), Argon, Hydrogen, Oxygen.

 

I used to work at an ASU as an operator and would help load trucks often. We had 9 different plants and made 5 products: N2,O2,Ar,LUX and GAN(gaseous N2.)

 

I would imagine there is, we have prax, air liquide, matheson, apci and linde. We even loaded a gen-ox(don't know anyting about them.)

 

If you want something really neat, try Gallium III. It's a soft metal that becomes liquid in your hands. Literally melting metal that does not burn you as molten metal like to. Its not a natural metal. You have to combine two substances to get it.

You will find it in the liquid silver doctors blood pressure machines as a alternative to mercury. When combined with 10% tin and 20 some percent something else you have a liquid that moves up and down and wont freeze until about -2 F.

 

Training class they described 'cold' burns and leather and canvass gauntlet gloves and then mentioned cutting the elastic on the back. said you want them loose so the can be shaken off if the get some of the cyro liquid on them. By the time you feel the burn it is too late, tissue damage has occurred...

 

YouTube "Man from LOX" it's a classic Navy LOX training video. Real eye opener of the hidden dangers of cryo.
