LD50 LC50 Mixture:NONE SPECIFIED BY MANUFACTURER.
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 MISUSE OR DELIBERATE INHALATION MAY CAUSE
DEATH WITHOUT WARNING. VAPOR RED UCES OXYGEN AVAILABLE FOR
BREATHING & IS HEAVIER THAN AIR. LIQUID CONTACT CAN CAUSE
FROSTBITE.
Explanation of Carcinogenicity:PER MSDS: CARCINOGENICITY: NONE OF
COMPONENTS PRESENT IN MATERIAL AT CONCENTRATIONS EQUAL TO/>0.1%
LISTED BY IARC/NTP/OSHA/ACGIH AS CARCINOGEN.
Effects of Overexposure:OVEREXPOSURE TO VAPORS BY INHALATION MAY
INCLUDE TEMPORARY NERVOUS SYSTEM DEPRESSION WITH ANESTHETIC EFFECTS
SUCH AS DIZZINESS, HEADACHE, CONFUSION, INCOORDINATION & LOSS OF
CONSCIOUSNESS. HIGHER EXPO SURES TO VAPORS MAY CAUSE TEMPORARY
ALTERATION OF HEART'S ELECTRICAL ACTIVITY WITH IRREGULAR PULSE,
PALPITATIONS OR INADEQUATE CIRCULATION; FATALITY FROM GROSS
OVEREXPOSURE. CONTACT WITH LIQUID MAY CA USE FROSTBITE.
Medical Cond Aggravated by Exposure:INDIVIDUALS WITH PREEXISTING
DISEASES OF THE CENTRAL NERVOUS OR CARDIOVASCULAR SYSTEM MAY HAVE
INCREASED SUSCEPTIBILITY TO THE TOXICITY OF INCREASED EXPOSURES.

First Aid:INHALATION: IMMEDIATELY REMOVE TO FRESH AIR. KEEP PERSON
CALM. IF NOT BREATHING GIVE ARTIFICIAL RESPIRATION. IF BREATHING IS
DIFFICULT GIVE OXYGEN. CALL PHYSICIAN. SKIN: FLUSH WITH LUKEWARM
WATER. DO NOT USE HOT WATER. IF FROSTBITE HAS OCCURRED CALL
PHSYICIAN. EYE:IMMEDIATELY FLUSH WITH PLENTY OF WATER FOR AT LEAST
15MINS. CALL PHYSICIAN. INGESTION: NOT PROBABLE ROUTE, HOWEVER IN
CASE OF ACCIDENTA L INGESTION CALL PHYSICIAN. NOTE TO PHYSICIAN:
CATECHOLAMINES SUCH AS ADRENALINE & OTHER COMPOUNDS HAVING SIMILAR
EFFECTS SHOULD BE RESERVED FOR EMERGENCIES & THEN ONLY USED WITH
SPECIAL CAUTION.

Flash Point:WILL NOT BURN
Autoignition Temp:Autoignition Temp Text:UNK
Extinguishing Media:AS APPROPRIATE FOR COMBUSTIBLES IN AREA.
Fire Fighting Procedures:COOL CYLINDER WITH WATER SPRAY OR FOG.
SELF-CONTAINED BREATHING APPRATUS (SCBA) IS REQUIRED IF CYLINDERS
RUPTURE & CONTENTS ARE RELEASED UNDER FIRE CONDITIONS. WATER RUNOFF
SHOULD BE CONTAINED & NEUTR ALIZED PRIOR TO RELEASE.
Unusual Fire/Explosion Hazard:NOT FLAMMABLE UP TO 212F & ATMOSPHERIC
PRESSURE. BUT MIXTURES IN HIGH CONCENTRATIONS OF AIR AT ELEVATED
TEMPERATURE CAN BECOME COMBUSTIBLE AT AMBIENT TEMPERATURE. AS
TEMPERATURE IS INCREASED, LOWER PR ESSURE (STILL > ATMOSPHERIC) CAN
CREATE SAME EFFECT. THEREFORE PRODUCT SHOULD NOT BE MIXED WITH AIR
UNDER PRESSURE.

Spill Release Procedures:REVIEW FIREFIGHTING MEASURES &
HANDLING/STORAGE SECTIONS BEFORE CLEANUP. USE APPROPRIATE PPE
DURING CLEANUP. VENTILATE AREA WITH FORCED VENTILATION, ESPECIALLY
IN LOW OR ENCLOSED AREAS WHERE VAPORS CA N COLLECT. REMOVE OPEN
FLAMES. USE SELF-CONTAINED BREATHING APPARATUS (SCBA) FOR LARGE
SPILLS OR RELEASES.
Neutralizing Agent:NONE SPECIFIED BY MANUFACTURER.

Handling and Storage Precautions:AVOID BREATHING VAPOR. AVOID LIQUID
CONTACT WITH EYES & SKIN. USE WITH SUFFICIENT VENTILATION. CONTACT
WITH CHLORINE OR OTHER STRONG OXIDIZERS SHOULD BE AVOIDED. STORE IN
CLEAN, DRY AREA. DO NOT HEAT ABOVE 52C (125F).
Other Precautions:CONTACT OF WELDING OR SOLDERING TORCH FLAMES WITH
HIGH CONCENTRATION OF REFRIGERANT CAN RESULT IN VISIBLE CHANGES IN
SIZE & COLOR OF TORCH FLAMES. THIS EFFECT WILL ONLY OCCUR IN
CONCENTRATIONS WELL AB OVE RECOMMENDED EXPOSURE LIMIT. THEREFORE
STOP ALL WORK & VENTILATE TO DISPERSE VAPORS BEFORE USING OPEN
FLAMES.

Respiratory Protection:UNDER NORMAL MANUFACTURING CONDITONS NO
RESPIRATORY PROTECTION IS REQUIRED WHEN USING PRODUCT.
SELF-CONTAINED BREATHING APPARATUS REQUIRED IF LARGE RELEASES
OCCURS.
Ventilation:LOCAL EXHAUST SHOULD BE USED IF LARGE AMOUNTS ARE RELEASED.
MECHANICAL VENTILATION SHOULD BE USED IN LOW OR ENCLOSED PLACES.
Protective Gloves:IMPERVIOUS GLOVES.
Eye Protection:CHEM SPLASH GOGGLES.
Other Protective Equipment:NONE SPECIFIED BY MANUFACTURER.
Work Hygienic Practices:NONE SPECIFIED BY MANUFACTURER.
