you should wear long gloves up to the elbows.

i used to work at the new york hall of science,  a children's hands-on museum, where we did demonstrations- one which involved liquid nitrogen. balloons would be placed in a pot of the liquid which shrunk the balloons to 1/10 their sizes. as they warmed up to room temperature, their sizes were restored and the kids went crazy over it!  :o(of course we gave the molecular explanations ;D)

in any case, we had to wear gloves up to the elbows and no shorter. the reasons they gave was exactly that which was mentioned here- a splash inside the glove will cause burns.
goggles which sealed around the eyes, and some sort of poly apron was required.
there was a part of the demo where the nitrogen was poured over an empty balloon then was smashed into bits.
ooo the molecular interest soared with that one  8)
