Health Hazards Acute and Chronic:NRTROGEN IS NONTOXIC, BUT MAY PRODUCE
    SUFFOCATION BY DISPLACING THE OXYGEN IN THE AIR. EXPOSURE TO
    OXYGEN- DEFICIENT ATMOSPHERES MAY CAUSE DIZZINESS, NAUSEA,
    VOMITING, DIMINISHED MENTAL ALERTNESS, LOS S OF CINSCIOUSNESS &
    DEATH.
Explanation of Carcinogenicity:NOT LISTED BY IARC, NTP OR OSHA.
Effects of Overexposure:PROLONGED BREATHING OF VERY COLD ATMOSPHERES
    CAN CAUSE LUNG DAMAGE & HYPOTHERMIA. FROZEN TISSUES, CAUSED BY
    FROSTBITE ARE PAINLESS & APPEAR WAXY WITH A POSSIBLE YELLOW COLOR.
    THEY WILL BECOME SWOLLEN,  APINFUL, & PRONE TO INFECTION.
Medical Cond Aggravated by Exposure:NONE SPECIFIED BY MANUFACTURER.

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

    FRESH AIR. IF NOT BREATHING, ADMINISTER ARTIFICIAL RESPIRATION. IF
    BREATHING IS DIFFICULT, ADMINISTER OXYGEN. IF CONTACT WITH LIQUID
    HAS CAUS ED FROSTBITE, DO NOT RUB AREA, AS TISSUE DAMAGE MAY OCCUR.
    FLUSH AFFECTED AREA WITH WARM WATER. OBTAIN PROMPT MEDICAL
    ATTENTION IN BOTH CAESES. (SELF-CONTAINED BREATHING APPARATUS MAY
    BE NEEDED)

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

Extinguishing Media:MATERIAL IS NONFLAMMABLE. NITROGEN NEITHER
    BURNS/SUPPORTS COMBUSTION. USE MEDIA APPROPIATE FOR SURROUNDING

    IT WILL DISPLACE OXYGEN.
Unusual Fire/Explosion Hazard:CONTACT WITH "COLD" LIQUID OR GASEOUS
    NITROGEN MAY CAUSE FROSTBITE. VISIBILITY MAY BE DESCURED IN THIS
    "VAPOR CLOUD".

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

Spill Release Procedures:SHUT OFF NITROGEN SOURCE IF POSSIBLE. AVOID
    CONTACT WITH LIQUID NITROGEN OR ITS BOIL-OFF GAS. TO INCREASE RATE
    OF EVAPORATION SPRAY WITH LARGE AMOUNTS OF WATER FROM UPWIND. IF
    LEAKING FROM CONTAINER C ONTACT THE CLOSEST BIG THREE INDUSTRY.

Other Precautions:DEPLETION OF OXYGEN CONTENT IN AIR BY DISPLACEMENT
    WITH INERT GAS IS A POTENTIAL HAZARD. SAFE WORKING ATMOSPHERE IS
    CONSIDER TO BE 20.9% OXYGEN.

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