Explanation of Carcinogenicity:PER MSDS:NITROGEN NOT LISTED BY NTP,
    OSHA, OR IARC.
Effects of Overexposure:NITROGEN IS AN ASPHYXIANT. HEADACHE,
    DROWSINESS, DIZZINESS, EXCITATION, EXCESS SALIVATION, VOMITING AND
    UNCONSIOUSNESS. LACK OF OXYGEN CAN KILL.
Medical Cond Aggravated by Exposure:TOXICOLOGY & PHYS/CHEM PROPERTIES
    OF NITROGEN SUGGEST THAT OVEREXPOSURE IS UNLIKELY TO AGGRAVATE
    EXISTING MEDICAL CONDITIONS.

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

First Aid:INHALATION: REMOVE TO FRESH AIR. IF NOT BREATHING GIVE
    ARTIFICIAL RESPIRATION. IF BREATHING IS  DIFFICULT, QUALIFIED
    PERSONNEL MAY GIVE OXYGEN. CALL A PHYSICIAN. SKIN: FLUSH WITH
    WATER. INGESTION: PRO DUCT IS A GAS @ NORMAL TEMPERATURE &
    PRESSURE.  EYE: FLUSH WITH WARM WATER.HOLD EYELIDS OPEN,AWAY FRM
    EYEBALLS TO ENSURE THAT ALL SURFACES ARE FLUSHED THOROUGHLY. NOTES
    TO DR: NO SPECIFIC ANTIDOTE. PR ODUCT IS  NEARLY INERT. TREATMENT
    OF OVEREXPOSURE  SHOULD BE DIRECTED  AT CONTROL OF SYMPTIONS AND
    THE CLINICAL CONDITION

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

Lower Limits:N/APPLICABLE
Upper Limits:N/APPLICABLE
Extinguishing Media:NITROGEN CANNOT CATCH FIRE. USE MEDIA APPROPRIATE
    FOR SURROUNDING FIRE.
Fire Fighting Procedures:CAUTION! HIGH PRESSURE GAS. EVACUATE ALL
    PERSONNEL FRM DANGER AREA. IMMEDIATELY DELUGE  CYLINDERS WITH WATER
    FROM MAXIMUM DISTANCE UNTIL COOL, THEN MOVE AWAY FROM AREA IF WITH
    OUT RISK. SELF CONTAINED  BREATHING APPRATTUS MAY BE REQUIRED
    BYRESCUE WORKERS. ON-SITE FIRE BRIGADES MUST COMPLY WITH OSHA 29
    CFR 1910.156.
Unusual Fire/Explosion Hazard:NITROGEN CANNOT CATCH FIRE.HEAT OF FIRE
    CAN BUILD PRESSURE IN CYLINDER AND CAUSE IT TO RUPTURE. NO PART OF
    CYLINDER SHOULD BE SUBJECT TO A TEMPERATURE HIGHER THAN 125 DEG F
    (52 DEG C). NITROGEN CYLIND ERS ARE EQUIPPED WITH A PRESSURE
    RELIEFDEVICE (EXCEPTIONS MAY EXIST WHERE AUTHORIZED BY DOT).

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

Spill Release Procedures:CAUTION! HIGH PRESSURE GAS. IMMEDIATELY
    EVACUATE ALL PERSONNEL FROM DANGER AREA. NITROGEN IS ASPHYXIANT.
    LACK OF OXYGEN CAN KILL. USE SELF CONTAINED BREATHING APPRATTUS 
    WHERE NEEDED. SHUT OFF FLOW  I F YOU CAN DO SO  WITH OUT RISK.
    VENTILATE  AREA OR MOVE CYLINDER TO WELL VENTILATED  AREA. TEST FOR
    SUFFICIENT OXYGEN EXPECIALLY IN CONFINED SPACES BEFORE ALLOW ING
    REENTRY.
Neutralizing Agent:NONE SPECIFIED BY MANUFACTURER.

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

Handling and Storage Precautions:STORE/ USE WITH ADEQUATE VENTILATION.
    FIRMLY SECURE CYLINDERS UPRIGHT TO KEEP FROM FALLING OR BEING
    KNOCKED OVER. SCREW VALVE PROTECTION CAP FIRMLY IN PLACE BY HAND.
    STORE FULL & EMPTY CYLINDERS SEPAR ATELY. USE FIRST-IN, FIRST-OUT
    INVENTORYSYSTEM TO PREVENT STORING FULL CYLINDERS FOR LONG PERIODS.
Other Precautions:PROTECT CYLINDERS FROM DAMAGE. USE SUITABLE HAND
    TRUCK TO MOVE CYLINDERS; DO NOT DRAG, ROLL, SLIDE, OR DROP. NEVER
    ATTEMPT TO LIFT CYLINDER BY ITS CAP; THE CAP IS INTENDED SOLELY TO
    PROTECT THE VALVE.	NEVER INSERT AN OBJECT (E.G. WRENCH,
    SCREWDRIVER, PRY BAR)  INTO CAP OPENING; DOING SO MAY DAMAGE (
    SUPPLEMENT)

    SUPPLIED RESPIRATORS ARE REQUIRED WHILE WORKING IN CONFINED SPACES
    WITH THIS PRODUCT. RESPIRATORY PROTECTION MUST CONFORM TO OSHA
    RULES SPECIFIED IN 29 CFR  1910.134.
Ventilation:LOCAL EXHAUST IF NECESSARY, TO PREVENT OXYGEN DEFICIENCY.
    MECHANICAL(GEN)-MAY BE ACCEPTABLE IF IT CAN MAINTAIN ADEQUATE
    SUPPLY OF AIR.
Protective Gloves:WORK GLOVES WHEN HANDLING CYLINDERS.
Eye Protection:SAFETY GLASSES WHEN  HANDLING  CYLINDERS.
Other Protective Equipment:METATARSAL SHOES FOR CYLINDER HANDLING.
