Recommendations for skin protection
Prevent skin contact....Wear appropriate personal protective clothing to prevent skin contact. Suggested barriers for use should be confirmed with the vendor and for additional information and use limitations.
Frostbite....................Wear appropriate personal protective clothing to prevent the skin from becoming frozen from contact with the evaporating liquid or from contact with vessels containing the liquid.
N.R...........................No specific recommendation can be made. Actual working conditions will determine the need and type of personal protective equipment.
