Routes of Entry: Inhalation:YES  Skin:NO  Ingestion:NO
Reports of Carcinogenicity:NTP:NO    IARC:NO	OSHA:NO
Health Hazards Acute and Chronic:INHALATION OF HIGH CONCENTRATION OF
    VAPOR IS HARMFUL & MAY CAUSE HEART IRREGULARITIES, UNCONSCIOUSNESS
    OR DEATH. INTENTIONAL MISUSE OR DELIBERATE INHALATION MAY CAUSE
    DEATH WITHOUT WARNING. VAPOR REDU CES OXYGEN AVAILABLE & IS HEAVIER
    THAN AIR. LIQUID CONTACT CAN CAUSE FROSTBITE.
Explanation of Carcinogenicity:NONE SPECIFIED BY MANUFACTURER.
Effects of Overexposure:EYES: IRRITATION, TEARING, BLURRED VISION.
    SKIN: TEMPORARY TINGLING, NUMBNESS, COLDNESS, DRYING OF SKIN.
    INHALATION: NAUSEA, HEADACHE, WEAKNESS, DIZZINESS, CONFUSION,
    INCOORDINATION, LOSS OF CONSCIOUS NESS, IRREGULAR PULSE,
    PALPITATIONS.
Medical Cond Aggravated by Exposure:INDIVIDUALS WITH PREEXISTING
    DISEASES OF THE CENTRAL NERVOUS, CARDIOVASCULAR, OCULR OR
    REPRODUCTIVE SYSTEM(S) MAY HAVE INCREASED SUSCEPTIBILITY TO THE
    TOXICITY OF EXCESSIVE EXPOSURES.

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

First Aid:INHALATION: REMOVE TO FRESH AIR, IF NOT BREATHING, GIVE
    ARTIFICIAL RESPIRATION, IF BREATHING IS DIFFICULT, GIVE OXYGEN.
    CALL A PHYSICIAN. EYES: FLUSH WITH WATER FOR AT LEAST 15 MINUTES.
    CALL A PHYSICI AN. SKIN: FLUSH WITH WATER FOR AT LEAST15 MINUTES.
    TREAT FOR FROSTBITE IF NECESSARY BY GENTLY WARMING THE AFFECTED
    AREA. GET MEDICAL ATTENTION IF IRRITATION IS PRESENT.

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

Flash Point Method:TOC
Flash Point:NONE
Extinguishing Media:NON-FLAMMABLE. USE EXTINGUISHING MEDIA APPROPIATE
    FOR SURROUNDING FIRE.
Fire Fighting Procedures:FIRE FIGHTERS SHOULD USE NIOSH APPROVED SCBA &
    FULL PROTECTIVE EQUIPMENT WHEN FIGHTING CHEMICAL FIRE. USE WATER
    SPRAY TO COOL NEARBY CONTAINERS EXPOSED TO FIRE.
Unusual Fire/Explosion Hazard:FIRE OR EXCESSIVE HEAT MAY CAUSE
    PRODUCTION OF HAZARDOUS DECOMPOSITION PRODUCTS. CYLINDERS MAY
    RUPTURE OR RELEASE UNDER FIRE CONDITIONS. NO2 IS AN OXIDIZER.

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

Spill Release Procedures:REMOVE PERSONNEL, VENTILATE AREA, ESPECIALLY
    IN LOW AREAS WHERE VAPOR MIGHT COLLECT, REMOVE OPEN FLAMES. WEAR
    SELF- CONTAINED BREATHING APPARATUS. STOP LEAK IF SAFE TO DO SO.
    OTHERWISE, LET EVAPORATE.
Neutralizing Agent:NONE SPECIFIED BY MANUFACTURER.

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

Handling and Storage Precautions:STORE CONTAINERS IN CLEAN DRY AREA. DO
    NOT HEAT ABOVE 125F.
Other Precautions:AVOID BREATHING HIGH CONCENTRATIONS OF VAPOR. AVOID
    CONTACT OF SKIN OR EYES WITH LIQUID OR COLD VAPORS. USE WITH
    ADEQUATE VENTILATION TO KEEP EMPLOYEE EXPOSURE BELOW RECOMMENDED
    LIMITS.

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

Respiratory Protection:NONE REQUIRED UNDER NORMAL CONDITIONS OF USE.
    SELF-CONTAINED BREATHING APPARATUS IS REQUIRED IF A SPILL OCCURS.
Ventilation:MECHANICAL VENTILATION IN LOW OR ENCLOSED PLACES. LOCAL
    EXHAUST WHEN LARGE AMOUNTS ARE RELEASED.
Protective Gloves:LINED LEATHER GLOVES.
Eye Protection:CHEMICAL SPLASH GOGGLES.
Other Protective Equipment:NONE.
Work Hygienic Practices:STANDARD PRACTICES AND RECOMMENDED PROCEDURES.
Supplemental Safety and Health
NOTE TO PHYSICIAN: BECAUSE OF POSSIBLE DISTURBANCES OF CARDIAC RHYTHM,
    CATECHOLAMINE DRUGS, SUCH AS EPINEPHRINE, SHOULD BE USED WITH
    SPECIAL CAUTION IN SITUATIONS OF EMERGENCY LIFE SUPPORT.
