    AIR NECESSARY TO SUPPORT LIFE.
Explanation of Carcinogenicity:NONE
Effects of Overexposure:INHALATION MAY CAUSE DIZZINESS, TIGHTNESS IN
    FRONTAL AREA OF FOREHEAD, TINGLING OF TONGUE, FINGERTIPS, TOES,
    WEAKENED SPEECH WITH INABILILTY TO UTTER SOUND, RAPID REDUCTION IN
    ABILITY TO PERFORM MOVEM ENTS, REDUCED CONSCIOUSNESS OF
    SURROUNDINGS, LOSS OF TACTILE SENSATIONS, HEIGHTENED MENTAL

Other Precautions:FIRMLY SECURE CYLINDERS TO PREVENT FALLING. SEGREGATE
    FULL AND EMPTY CYLINDERS. USE FIRST IN FIRST OUT SYSTEM. USE ONLY
    IN WELL VENTILATED AREA. USE SUITABLE HAND TRUCK FOR CYLINDER
    MOVEMENT. DO NOT H EAT CYLINDER TO INCREASE DISCHARGE RATE.

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

Respiratory Protection:POSITIVE PRESSURE AIR LINE WITH MASK OR SELF
    CONTAINED BREATHING APPARATUS SHOULD BE AVAILABLE FOR EMERGENCY
    USE.
Ventilation:USE LOCAL EXHAUST TO PREVENT ACCUMULATION OF HIGH
