Reports of Carcinogenicity:NTP:NO IARC:NO OSHA:NO
Health Hazards Acute and Chronic:INHALATION: VAPOR IS HEAVIER THAN AIR
AND CAN CAUSE SUFFOCATION BY REDUCING OXYGEN AVAILABLE FOR
BREATHING. BREATHING HIGH CONCENTRATIONS OF VAPOR MAY CAUSE
LIGHT-HEADEDNESS, GIDDINESS, SHORTNESS OF B REATH, AND MAY LEAD TO
NARCOSIS, CARDIAC IRREGULARITIES, UNCONSCIOUSNESS OR DEATH.
SKIN/EYE: IRRITATION AND FROSTBITE.
Explanation of Carcinogenicity:DICHLORODIFLUOROMETHANE (FREON 12) IS
NOT LISTED AS A CARCINOGEN BY IARC, NTP OR OSHA.
Effects of Overexposure:BREATHING HIGH CONCENTRATIONS OF VAPOR MAY
CAUSE LIGHT-HEADEDNESS, GIDDINESS, SHORTNESS OF BREATH, AND MAY
LEAD TO NARCOSIS, CARDIAC IRREGULARITIES, UNCONSCIOUSNESS OR DEATH.
LIQUID IS IRRITATING TO S KIN AND EYES, AND MAY CAUSE FROSTBITE.
Medical Cond Aggravated by Exposure:PERSONS WITH KNOWN HISTORY OF HEART
DISEASE OR IRREGULARITIES OF HEARTBEAT SHOULD BE PARTICULARY
CAREFUL TO AVOID OVEREXPOSURE TO THESE VAPORS.

First Aid:INALATION: REMOVE TO FRESH AIR, CALL A PHYSICIAN. IF NOT
BREATHING, GIVE ARTIFICIAL RESPIRATION. IF BREATHING IS DIFFICULT,
GIVE OXYGEN. DO NOT GIVE EPINEPHRINE OR SIMILAR DRUGS. EYE: FLUSH
WITH WATER FOR AT LEAST 15 MINUTES. GET MEDICAL ATTENTION. SKIN:
WASH WITH SOAP AND WATER. IF FROSTBITE, WARM SKIN SLOWLY. GET
MEDICAL ATTENTION.

Extinguishing Media:USE WATER FOG, CARBON DIOXIDE, FOAM, OR DRY
CHEMICAL AS APPROPRIATE FOR SURROUNDINGS.
Fire Fighting Procedures:WEAR FIRE FIGHTING PROTECTIVE EQUIPMENT AND A
FULL FACED SELF CONTAINED BREATHING APPARATUS. EVACUATE AREA. COOL
FIRE EXPOSED CONTAINERS WITH WATER SPRAY.
Unusual Fire/Explosion Hazard:COMBUSTION OR HEAT OF FIRE MAY PRODUCE
HAZARDOUS DECOMPOSITION PRODUCTS AND VAPORS.

Spill Release Procedures:VENTILATE AREA. KEEP UPWIND, EVACUATE ENCLOSED
SPACE. DISPERSE GAS WITH FLOOR-LEVEL FORCED AIR VENTILATION OR
WATER SPRAY. DO NOT SMOKE. REMOVE FLAMES, HEATING ELEMENTS, GAS
