LD50 LC50 Mixture:THE BLEND IS UNTESTED.
Routes of Entry: Inhalation:YES Skin:YES Ingestion:NO
Reports of Carcinogenicity:NTP:NO IARC:NO OSHA:NO
Health Hazards Acute and Chronic:INHALATION OF HIGH CONCENTRATIONS OF
VAPOR IS HARMFUL & MAY CAUSE HEART IRREGULARITIES, UNCONSCIOUSNESS,
OR DEATH. INTENTIONAL MISUES OR DELIBERATE INHALATION MAY CAUSE
DEATH WITHOUT WARNING. VAPOR RE DUCES OXYGEN AVAILABLE FOR
BREATHING AND IS HEAVIER THAN AIR. LIQUID CONTACT CAN CAUSE
FROSTBITE.
Explanation of Carcinogenicity:NOT CARCINOGENIC.
Effects of Overexposure:OVEREXPOSURE TO THE VAPORS BY INHALATION MAY
INCLUDE TEMPORARY NERVOUS SYSTEM DEPRESSION WITH ANESTHETIC EFFECTS
SUCH AS DIZZINESS, HEADACHE, CONFUSION, INCOORDINATION AND LOSS OF
CONSCIOUSNESS. HIGHE R EXPOSURES TO THE VAPORS MAY CAUSE TEMPORARY
ALTERATION OF THE HEARTS ELECTRICAL ACTIVITY WITH IRREGULAR PULSE,
PALPITATION, OR INADEQUATE CIRCULATION; OR FATALITY FROM GROSS
OVEREXPOSURE. CONTACT WI TH LIQUID CAN CAUSE FROSTBITE.
Medical Cond Aggravated by Exposure:INDIVIDUALS WITH PREEXISTING
DISEASE OF THE CENTRAL NERVOUS OR CARDIOVASCULAR SYSTEM MAY HAVE
INCREASED SUSCEPTIBILITY TO THE TOXICITY OF INCREASED EXPOSURE.

First Aid:INHALATION: REMOVE TO FRESH AIR. KEEP PERSON CALM, IF NOT
BREATHING, GIVE ARTIFICIAL RESPIRATION. IF BREATHING IS DIFFICULT,
GIVE OXYGEN. SKIN: FLUSH WITH LUKE WARM WATER. DO NOT USE HOT
WATER. IF FRO STBITE HAS OCCURRED, CALL A PHYSICIAN. EYES:
IMMEDIATELY FLUSH EYES WITH PLENTY OF WATER FOR 15 MINUTES.CALL A
PHYSICIAN. INGESTION: NOT A PROBABLE ROUTE; HOWEVER, INCASE OF

CONDITIONS. DECOMPOSITION MAY OCCUR.

Spill Release Procedures:VENTILATE AREA USING FORCED VENTILATION,
ESPECIALLY IN LOW/ENCLOSED PLACES WHERE HEAVY VAPORS MIGHT COLLECT.
