=====================  Hazards Identification  =====================

Reports of Carcinogenicity:NTP:NO    IARC:NO	OSHA:NO
Health Hazards Acute and Chronic:INHALATION OF HIGH CONCENTRATIONS OF
    VAPORS IS HARMFUL AND MAY CAUSE HEART IRREGULARITIES,
    UNCONSCIOUSNESS, OR DEATH. INTENTIONAL MISUSE OR DELIBERATE
    INHALTION MAY CAUSE DEATH WITHOUT WARNING. VAPOR  REDUCES OXYGEN
    AVAILABLE FOR BREATHING AND IS HEAVIER THAN AIR. LIQUID CONTACT CAN
    CAUSE FROSTBITE. MAY CAUSE EYE IRRITATION.
Explanation of Carcinogenicity:NONE OF THE COMPONENTS PRESENT IN THIS
    MATERIAL AT CONCENTRATIONS EQUAL TO OR GREATER THAN 0.1% ARE LISTED
    BY IARC, NTP, OSHA OR ACGIH AS A CARCINOGEN.
Effects of Overexposure:HUMAN HEALTH EFFECTS OF OVEREXPOSURE BY EYE
    CONTACT WITH THE VAPOR MAY INCLUDE EYE IRRITATION WITH DISCOMFORT,
    TEARING, OR BLURRING OF VISION. SKIN CONTACT WITH THE LIQUID MAY
    CAUSE FROSTBITE. INHALAT ION OF THE VAPORS MAY CAUSE TEMPORARY
    NERVOUS SYSTEM DEPRESSION WITH ANESTHETIC EFFECTS SUCH AS
    DIZZINESS, HEADACHE, CONFUSION, INCOORDINATION, AND LOSS OF
    CONSCIOUSNESS; TEMPORARY ALTERATION OF HEART 'S ELECTRICAL ACTIVITY
    WITH IRREGULAR PULSE, PALPITATIONS, OR INADEQUATE CIRCULATION, OR
    THE EFFECTS OF EXCLUSION OF OXYGEN WITH GROSSLY EXCESSIVE EXPOSURE.
Medical Cond Aggravated by Exposure:INDIVIDUALS WITH PREEXISTING
    DISEASES OF CENTRAL NERVOUS OR CARDIOVASCULAR SYSTEM MAY HAVE
    INCREASED SUSCEPTIBILITY TO THE TOXICITY OF EXCESSIVE EXPOSURE.

=======================  First Aid Measures  =======================

First Aid:INHALATION: IF HIGH CONCENTRATIONS ARE INHALED, IMMEDIATELY
    REMOVE TO FRESH AIR. KEEP PERSON CALM. IF NOT BREATHING, GIVE
    ARTIFICIAL RESPIRATION. IF BREATHING IS DIFFICULT, GIVE OXYGEN.
    CALL PHYSICIAN . SKIN: FLUSH SKIN WITH WATER. TREAT FOR FROSTBITE
    IF NECESSARY BY GENTLY WARMING AFFECTED AREA. EYE: IMMEDIATELY
    FLUSH EYES WITH PLENTY OF WATER FOR AT LEAST 15 MINUTES. CALL
    PHYSICIAN. INGESTION: IN GESTION IS NOT CONSIDERED A POTENTIAL
    ROUTE OF EXPOSURE. NOTE: BECAUSE OF POSSIBLE DISTURBANCE OF CARDIAC
    RHYTHM, CATECHOLAMINE DRUGS, SUCH AS EPINEPHRINE, SHOULD ONLY BE
    USED WITH SPECIAL CAUTION IN  SITUATIONS OF EMERGENCY LIFE SUPPORT.

=====================  Fire Fighting Measures  =====================

Flash Point:WILL NOT BURN
Autoignition Temp:>750.C, 1382.F
Extinguishing Media:AS APPROPRIATE FOR COMBUSTIBLES IN AREA.
Fire Fighting Procedures:USE WATER SPRAY OR FOG TO COOL CONTAINERS.
    SELF-CONTAINED BREATHING APPARATUS IS REQUIRED IF CYLINDERS RUPTURE
    AND CONTENTS ARE RELEASED UNDER FIRE CONDITIONS.
Unusual Fire/Explosion Hazard:CYLINDERS MAY RUPTURE UNDER FIRE
    CONDITIONS. DECOMPOSITION MAY OCCUR.

==================  Accidental Release Measures  ==================

Spill Release Procedures:SAFEGUARDS (PERSONNEL). NOTE: REVIEW FIRE
    FIGHTING MEASURES & HANDLING (PERSONNEL) SECTIONS EFORE PROCEEDING

    CLEAN-UP. VENTILATE AREA , ESPECIALLY LOW OR ENCLOSED PLACES WHERE
    HEAVY VAPORS MIGHT COLLECT. REMOVE OPEN FLAMES. USE SELF-CONTAINED
    BREATHING APPARATUS(SCBA) FOR LARGE SPILLS.

======================	Handling and Storage  ======================

Handling and Storage Precautions:HANDLING (PERSONNEL): USE WITH
    SUFFICIENT VENTILATION TO KEEP EMPLOYEES EXPOSURE BELOW RECOMMENDED
    LIMITS. STORAGE: CLEAN, DRY AREA. DO NOT HEAT ABOVE 52 DEG C (125
    DEG F).
Other Precautions:NFPA, NPCA-HMIS. NPCA-HMIS RATING: HEALTH-1,
    FLAMMABILITY-0, REACTIVITY-1. PERSONAL PROTECTION RATING TO BE
    SUPPLIED BY USER DEPENDING ON USE CONDITIONS.

=============  Exposure Controls/Personal Protection  =============

Respiratory Protection:UNDER NORMAL MAUNFACTURING CONDITIONS, NO
    RESPIRATORY PROTECTION IS REQUIRED WHEN USING THIS PRODUCT.
