CAS:7727-37-9
RTECS #:QW9700000
&gt; Wt:99.

=====================  Hazards Identification  =====================

LD50 LC50 Mixture:NO DATA PROVIDED BY RESPONSIBLE PARTY.
Routes of Entry: Inhalation:YES  Skin:NO  Ingestion:NO
Reports of Carcinogenicity:NTP:NO    IARC:NO	OSHA:NO
Health Hazards Acute and Chronic:NITROGEN IS A NONTOXIC, ODORLESS,
    COLORLESS, NONFLAMMABLE COMPRESSED GAS STORED IN CYLINDERS AT HIGH
    PRESSURE.  IF CAN CAUSE RAPID SUFFOCATION WHEN CONCENTRATIONS ARE
    SUFFICIENT TO REDUCE OXYGEN LEVEL S BELOW 19.5%.  SELF CONTAINED
    BREATHING APPARATUS (SCBA) MAY BE REQUIRED. POTENTIAL HEALTH
    EFFECTS INFORMATION: INHALATION SIMPLE ASPHYXIANT. NITROGEN IS
    NONTOXIC, BUT MAY CAUSE SUFFOCATION BY DISPLA CING THE OXYGEN IN
    AIR.  LACK OF SUFFICIENT OXYGEN CAN CAUSE SERIOUS INJURY OR
    DEATH.EYE CONTACT: NO ADVERSE EFFECT. SKIN CONTACT: NO ADVERSE
    EFFECT.
Explanation of Carcinogenicity:NITROGEN IS NOT LISTED AS A CARCINOGEN
    OR POTENTIAL CARCINOGEN BY NTP, IARC OR OSHA.
Effects of Overexposure:EXPOSURE TO AN OXYGEN DEFICIENT
    ATMOSPHERE(<19.5%)MAY CAUSE DIZZINESS, DROWSINESS, NAUSEA,
    VOMITING, EXCESS SALIVATION, DIMINISHED MENTAL ALERTNESS, LOSS OF
    CONSCIOUSNESS AND DEATH. EXPOSURE TO ATMOSP HERES CONTAINING 8-10%
    OR LESS OXYGEN WILL BRING ABOUT UNCONSCIOUSNESS WITHOUT WARNING AND
    SO QUICKLY THAT THE INDIVIDUALS CANNOT HELP THEMSELVES.
Medical Cond Aggravated by Exposure:NONE.

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

First Aid:PERSONS SUFFERING FROM LACK OF OXYGEN SHOULD BE MOVED TO
    FRESH AIR.	IF VICTIM IS NOT BREATHING ADMINISTER ARTIFICIAL
    RESPIRATION.  IF BREATHING IS DIFFICULT, ADMINISTER OXYGEN.  OBTAIN
    PROMPT MEDICAL  ATTENTION.

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

Lower Limits:NONFLAMMABLE
Upper Limits:NONFLAMMABLE
Extinguishing Media:NITROGEN IS NONFLAMMABLE AND DOES NOT SUPPORT
    COMBUSTION. USE EXTINGUISHING MEDIA APPROPRIATE FOR THE SURROUNDING
    FIRE.
Fire Fighting Procedures:NITROGEN IS A SIMPLE ASPHYXIANT. IF POSSIBLE,
    REMOVE NITROGEN CYLINDERS FROM FIRE AREA OR COOL WITH WATER. SCBA
    MAY BE REQUIRED BY RESCUE WORKERS.
Unusual Fire/Explosion Hazard:UPON EXPOSURE TO INTENSE HEAT OR FLAME
    CYLINDER MAY VENT TEMPERATURES. PRESSURE IN A CONTAINER CAN  BULID
    BY DUE TO HEAT AND IT MAY RUPTURE IF PRESSURE RELIEF DEVICES SHOULD
    FAIL TO FUNCTION.

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

Spill Release Procedures:EVACUATE ALL PERSONNEL FROM AFFECTED AREA.
    INCREASE VENTILATION TO RELEASE AREA AND MONITOR OXYGEN LEVEL. USE
    APPROPRIATE PROTECTIVE EQUIPMENT (SCBA).  IF LEAK IS FROM CONTAINER
    OR ITS VALVE, CALL THE  AIR PRODUCTS EMERGENCY TELEPHONE NUMBER. 
    IF LEAK IS IN USERS SYSTEM CLOSE CYLINDER VALVE AND VENT PRESSURE
    BEFORE ATTEMPTING REPAIRS.
Neutralizing Agent:NO DATA PROVIDED BY RESPONSIBLE PARTY.

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

Handling and Storage Precautions:CYLINDERS SHOULD BE STORED UPRIGHT IN
    A WELLL-VENTILATED, SECURE AREA, PROTECTED FROM THE WEATHER STORAGE
    AREA TEMP. SHOULD NOT EXCEED 125F AND AREA SHOULD BE FREE OF
    COMBUSTIBLE MATERIALS.  STORAGE S HOULD BE AWAY FROM HEAVILY
    TRAVELED AREA AND EMERGENCY EXITS.
Other Precautions:DO NOT DRAG,ROLL,OR SLIDE CYLINDER.USE A SUITABLE
    HANDTRUCK DESIGNED FOR CYLINDER MOVEMENT.NEVER  ATTEMPT TO LIFT A
    CYLINDER BY ITS CAP. SECURE CYLINDERS AT ALL TIMES WHILE IN USE.USE
    A PRESSURE REDUC ING REGULATOR OR SEPARATE CONTROL VALVE TO SAFELY
    DISCHARGE GAS FROM CYLINDER.USE A CHECK VALVE TO P REVENT REVERSE
    FLOW

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

Respiratory Protection:GENERAL:NONE  EMERGENCY: USE SCBA OR POSITIVE
    PRESSURE AIR LINE WITH MASK AND ESCAPE PACK IN AREAS WHERE OXYGEN
    CONCENTRATION IS LESS THAN 19.5%.  AIR PURIFYING RESPIRATORS WILL
    NOT PROVIDE PROTECTION
Ventilation:PROVIDE GOOD VENTILATION OR LOCAL EXHAUST TO PREVENT
    ACCUMULATION OF HIGH CONCENTRATIONS OF GAS.
Protective Gloves:LEATHER WORK GLOVES
Eye Protection:SAFETY GLASSES.
Other Protective Equipment:SAFETY SHOES RECOMMENDED WHEN HANDLING
    CYLINDERS.
Work Hygienic Practices:NO DATA PROVIDED BY RESPONSIBLE PARTY.
Supplemental Safety and Health
OXYGEN LEVELS IN WORK AREA SHOULD BE MONITORED TO ENSURE THEY DO NOT
    FALL BELOW 19.5%. CAUTION: USERS OF NITROGEN MUST BE AWARE OF THE
    HAZARDS CAUSED BY ACCUMULATION OF HIGH CONCENTRATIONS, ESPECIALLY 
    IN CONFINED SPACES. COMPLIANCE WITH 29 CFR 1910.146 IS ESSENTIAL.
