HEALTH HAZARD DATA

TIME WEIGHTED AVERAGE EXPOSURE LIMIT

TWA = 800 Molar PPM (ACGIH 1994-1995). No PEL (8 hours TWA) listed by OSHA 1993.

SYMPTOMS OF EXPOSURE

Effects of exposure to high concentrations so as to displace the oxygen in the air necessary for life are headache, dizziness, labored breathing and eventual unconsciousness. Also, it is a narcotic which acts as a depressant on the central nervous system. Contact with the rapidly evaporating liquid can cause frostbite or cryogenic “burns”.
