Explanation of Carcinogenicity:NONE
Effects of Overexposure:TEMPORARY NERVOUS SYSTEM DEPRESSION WITH
    ANAESTHETIC EFFECTS SUCH AS DIZZINESS, HEADACHE, CONFUSION,
    INCOORDINATION, LOSS OF CONSCIOUSNESS, IRREGULAR PULSE,
    PALPITATIONS, INADEQUATE CIRCULATION, FROST BILTE, IRRITATION,
    BLURRED VISION, TEARING
Medical Cond Aggravated by Exposure:INDIVIDUALS WITH PREEXISTING
    DISEASES OF THE CENTRAL NERVOUS OR CARDIOVASCULAR SYSTEM MAY HAVE
    INCREASED SUSCEPTIBILITY TO THE TOXICITY OF EXCESSIVE EXPOSURE.

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

First Aid:GET MEDICAL ATTENTION IF NEEDED. EYE/SKIN: IMMEDIATELY FLUSH
    WITH PLENTY OF WATER. TREAT FOR FROSTBITE IF NEEDED. INHALED:
    REMOVE TO FRESH AIR & PROVIDE OXYGEN/CPR IF NEEDED. ORAL: INGESTION
    IS NOT CO NSIDERED A POTENTIAL ROUTE OF EXPOSURE.NOTE TO PHYSICIAN:
    CATECHOLAMINE DRUGS SHOULD BE USED WITH SPECIAL CAUTION ONLY IN

Extinguishing Media:WATER SPRAY, CARBON DIOXIDE, FOAM OR DRY CHEMICAL
    FOR SURROUNDING FIRE. USE WATER SPRAY TO COOL FIRE EXPOSED
    CYLINDERS.
Fire Fighting Procedures:WEAR PROTECTIVE CLOTHING AND NIOSH-APPROVED
    SELF-CONTAINED BREATHING APPARATUS. MOVE CYLINDERS FROM FIRE AREA
    IF POSSIBLE WITHOUT INCREASED PERSONAL RISK.
