Health Hazards Acute and Chronic:CHLOROFLUOROCARBON (CFC) MATLS HAVE
PRDCD SENSIT OF MYOCARDIUM TO EPINEPHRINE IN LAB ANIMALS & COULD
HAVE SIMILAR EFT IN HUMANS. ADRENOMIMETICS (E.G., EPINEPHRINE) MAY
BE CONTRAINDICATED EXCEPT FOR LI FE-SUSTAINING USES IN HUMANS
ACUTELY/CHRONICALLY EXPOS TO CFC'S . INHAL OF HIGH CONCS OF VAP IS
HARMFUL & MAY CAUSE HEART IRREGS, UNCON/DEATH. INTENTIONAL MISUSE
CAN BE FATAL. VAP REDUCES OXYG A VAIL FOR BRTHG & IS HVR/AIR. LIQ
CONT CAN CAUSE FROSTBITE. DYMEL 22:HUMAN HLTH EFTS OF OVEREXP TO
VAPS BY INHAL MAY INCL TEMPORARY NERV SYS DEPRESS W/ANESTH EFTS
SUCH AS DIZZ, HDCH, CONFUSN, INCOORD & LOSS OF CONSCIOUSNESS.(EFTS
OF OVEREXP)
Explanation of Carcinogenicity:THE COMPONENTS OF THESE BLENDS ARE NOT
LISTED AS CARCINOGENS BY IARC, NTP, OSHA, OR ACGIH. FOR INFORMATION
FROM DU PONT, SEE HEALTH HAZARD INFORMATION.
Effects of Overexposure:HLTH HAZ:HIGHER EXPOS TO VAPS MAY CAUSE
TEMPORARY ALTERATION OF HEART'S ELEC ACTIVITY W/IRREG PULSE,
PALPITATIONS/INADEQ CIRCULATION; OR FATALITY FROM GROSS OVEREXP.
SKIN CONT W/LIQ MAY CAUSE FROSTBIT E. DYMEL A:SKIN CONT W/LIQ MAY
CAUSE FREEZING OF SKIN. EYE CONT W/VAP MAY PRDCE EYE IRRIT
W/DISCOMFORT, TEARING/BLURRING OF VISION. OVEREXP BY INHAL TO VAPS
MAY CAUSE NONSPECIFIC DISCOMFORT, SUCH AS N AUS, HDCH/WEAKNESS.
HIGHER EXPOS TO VAPS MAY CAUSE TEMPORARY NERV SYS DEPRESS W/ANESTH
EFTS SUCH AS DIZZ, HDCH, CONFUSN, INCOORD & LOSS OF CONSCIOUSNESS;
OR INCR SUSCEPTIBILITY TO CARDIAC ARRHYTHMIC E FTS OF EPINEPHRINE.
Medical Cond Aggravated by Exposure:INDIVIDUALS WITH PREEXISTING
DISEASES OF THE CENTRAL NERVOUS OR CARDIOVASCULAR SYSTEM MAY HAVE
INCREASED SUSCEPTIBILITY TO THE TOXICITY OF EXCESSIVE EXPOSURES.

First Aid:INHALATION: IMMEDIATELY REMOVE TO FRESH AIR. KEEP PERSONS
CALM. IF NOT BREATHING, GIVE ARTIFICIAL RESPIRATION. IF BREATHING
IS DIFFICULT, GIVE OXYGEN. CALL MD. SKIN: FLUSH WITH WATER AFTER
EXCESSIVE C ONTACT. TREAT FOR FROSTBITE IF NECESSARY. EYES:
IMMEDIATELY FLUSH WITH PLENTY OF WATER FOR AT LEAST 15 MINUTES.
CALL MD. INGESTION: CALL MD IMMEDIATELY . NOT CONSIDERED A
POTENTIAL ROUTE OF EXPO SURE. NOTE TO MD'S: BECAUSE OF A POSSIBLE
DISTURBANCE OF CARDIAC RHYTHM, CATECHOLAMINE DRUGS, SUCH AS
EPINEPHRINE, SHOULD BE USED WITH SPECIAL CAUTION ONLY IN SITUATIONS
OF EMERGENCY LIFE SUPPORT.
