Reports of Carcinogenicity:NTP:NO IARC:NO OSHA:NO
Health Hazards Acute and Chronic:INHALATION MAY CAUSE HEART
IRREGULARITIES, UNCONSCIOUSNESS OR DEATH. INTENTIONAL MISUSE CAN BE
FATAL. VAPOR REDUCES OXYGEN AVAIL FOR BREATHING & IS HEAVIER THAN
AIR. LIQUID CONTACT CAN CAUSE FROSTBITE . OVEREXPOSURE BY
INHALATION, INGESTION, SKIN, EYE CONTACT MAY CAUSE: TEMP NERVOUS
SYSTEM DEPRESSION W/ANESTHETIC***
Explanation of Carcinogenicity:**MG/KG-RAT.
Effects of Overexposure:***EFFECTS SUCH AS DIZZINESS, HEADACHE,
CONFUSION, INCOORDINATION & LOSS OF CONSCIOUSNESS; TEMPORARY
ALTERATION OF THE HEART'S ELECTRICAL ACTIVITY W/IRREGULAR PULSE,
PALPITATIONS OR INADEQUATE CIRCULA TION OR THE EFFECTS OF EXCLUSION
OF OXYGEN W/GROSS OVEREXPOS. SIGNIFICANT SKIN PERMEATION AFTER
CONTACT APPEARS LIKELY.

First Aid:INHALATION: REMOVE TO FRESH AIR. IF NOT BREATHING, GIVE
ARTIFICIAL RESPIRATION, PREFERABLY MOUTH-TO-MOUTH. IF BREATHING IS
DIFFICULT, GIVE OXYGEN. CALL PHYSICIAN. SKIN: FLUSH W/WATER. TREAT
FOR FROSTB ITE IF NECESSARY. EYE: IMMEDIATELY FLUSH EYES W/PLENTY
OF WATER. CALL PHYSICIAN. INGESTION: NOT LIKELY TO BE HAZARDOUS BY

APPARATUS IS REQUIRED IF A LARGE RELEASE OCCURS.
Ventilation:LOCAL EXHAUST SHOULD BE USED WHEN LARGE AMOUNTS ARE
RELEASED. MECHANICAL VENTILATION SHOULD BE USED IN LOW PLACES.
Protective Gloves:LINED BUTYL GLOVES
