Protective Equipment / Clothing

Wear protective gloves and clothing to prevent any reasonable probability of skin contact ... Viton and butyl rubber are among the recommended protective materials ... Contact lenses should not be worn when working with this chemical. Wear gas-proof chemical goggles and face shield unless full-facepiece respiratory protection is worn ...
Compressed gases may create low temperatures when they expand rapidly. Leaks and uses that allow rapid expansion may cause a frostbite hazard. Wear appropriate personal protective clothing to prevent the skin from becoming frozen.
Wear appropriate eye protection to prevent eye contact with the liquid that could result in burns or tissue damage from frostbite.
Quick drench facilities and/or eyewash fountains should be provided within the immediate work area for emergency use where there is any possibility of exposure to liquids that are extremely cold or rapidly evaporating.
