Health Hazards Acute and Chronic:EYES: CONTACT WITH LIQUID MAY CAUSE
FROSTBITE, IRRITATION OR BLINDNESS. SKIN: CONTACT WITH LIQUID WILL
CAUSE FROSTBITE OR IRRITATION. INGESTION: INGESTION IS UNLIKELY.
THE EFFECTS OF INGESTION ARE UNK NOWN. HOWEVER, MINIMAL HEALTH
EFFECTS ARE ANTICIPATED. CONSULT A PHYSICIAN FOR TREATMENT OR
CONTACT THE LOCAL POISON CONTROL CENTER. INHALATION: THIS GAS
MIXTURE IS A CENTRAL NERVOUS SYSTEM DEPRESSANT AND IRRITANT.
INHALATION OF LOW CONCENTRATIONS MAY CAUSE EXCITEMENT AND
DISORIENTATION. IN HIGHER CONCENTRATIONS, THIS MIXTURE MAY ACT AS
AN ASPHYXIANT SO AS TO EXCLUDE AN ADEQUATE SUPPLY OF OXYGEN T O THE
LUNGS, (EFFECTS OF OVEREXPOSURE)
Effects of Overexposure:HEALTH HAZARDS: CAUSING UNCONSCIOUSNESS AND
POSSIBLY DEATH. EFFECTS OF OXYGEN DEFICIENCY RESULTING FROM SIMPLE
ASPHYXIANTS MAY INCLUDE RAPID BREATHING, DIMINISHED MENTAL
ALERTNESS, IMPAIRED MUSCULAR C OORDINATION, FAULTY JUDGEMENT,
DEPRESSION OF ALL SENSATIONS, EMOTIONAL INSTABILITY, AND FATIGUE.
AS ASPHYXIANT PROGRESSES, NAUSEA, VOMITING, PROSTRATION, AND LOSS
OF CONSCIOUSNESS MAY RESULT, EVENTUAL LY LEADING TO CONVULSIONS,
COMA, AND DEATH. OXYGEN DEFICIENCY DURING PREGNANCY HAS PRODUCED
DEVELOPMENTAL ABNORMALITIES IN HUMANS AND EXPERIMENTAL ANIMALS.

First Aid:EYES: NEVER INTRODUCE OIL/OINTMENT INTO EYES W/OUT MED
ADVICE! IN CASE OF FREEZING/CRYOGENIC "BURNS" BY RAPIDLY
EVAPORATING LIQ, DO NOT WASH EYES W/HOT OR EVEN TEPID WATER! REMOVE
VICTIM FROM SOURCE O F CONTAM. OPEN EYELIDS WIDE TO ALLOW LIQ TO
EVAP. IF PAIN IS PRESENT, REFER VICTIM TO OPHTHALMOLOGIST FOR
FURTHER TREATMENT & FOLLOW UP. IF VICTIM CANNOT TOLERATE LIGHT,
PROTECT EYES W/LIGHT BANDAGE/H ANDKERCHIEF. FLUSH WITH POTABLE
WATER FOR AT LEAST 15 MINUTES. SEE MD . SKIN: REMOVE CONTAM CLTHG &
FLUSH AFFECTED AREA W/LUKEWARM WATER. DO NOT USE HOT WATER. INGEST:
KEEP VICTIM CALM & WARM. ( SUP DAT)
