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

LD50 LC50 Mixture:NONE PROVIDED BY MFR.
Reports of Carcinogenicity:NTP:NO    IARC:NO	OSHA:NO
Health Hazards Acute and Chronic:NITROGEN IS NONTOXIC BUT THE
    LIBERATION OF A LARGE AMOUNT IN A CONFINED AREA COULD DISPLACE THE
    AMOUNT OF OXYGEN IN AIR NECESSARY TO SUPPORT LIFE. FROSTBITE
    EFFECTS ARE A CHANGE IN COLOR OF THE SKIN T O GRAY OR WHITE
    POSSIBLY FOLLOWED BY BLISTERING. CONTACT WITH THE CRYOGENIC LIQUID
    OR COLD PIPING CONTAINING THE LIQUID CAN CAUSE TISSUE FREEZING OR
    FROSTBITE ON DERMAL CONTACT OR IF SPLASHED INTO THE  EYES.
Explanation of Carcinogenicity:NONE PROVIDED BY MFR.
Effects of Overexposure:EFFECTS OF EXPOSURE TO HIGH CONCENTRATIONS THAT
     DISPLACES OXYGEN IN AIR NECESSARY FOR LIFE MAY INCLUDE ANY, ALL,
    OR NONE OF FOLLOWING:  LOSS OF BALANCE, DIZZINESS, TIGHTNESS IN 
    FRONTAL AREA OF FOREH EAD, TINGLING OF TONGUE, FINGERTIPS, TOES,
    WEAKENED SPEECH LEADING TO INABILITY TO UTTER SOUNDS, RAPID
    REDUCTION IN ABILITY TO PERFORM MOVEMENTS, REDUCED CONSCIOUSNESS OF
    SURROUNDINGS, LOSS OF TACTILE  SENSATIONS, HEIGHTENED MENTAL
    ACTIVITY. IT SHOULD BE RECONGNIZED THAT IT IS POSSIBLE THAT NONE OF
    ABOVE SYMPTOMS MAY OCCUR IN NITROGEN ASPHYXIA SO THAT THERE ARE NO
    DEFINITE WARNING SYMPTOMS.

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

First Aid:PROMPT MEDICAL ATTENTION IS MANDATORY IN ALL CASES OF
    OVEREXPOSURE TO NITROGEN. RESCUE PERSONNEL SHOULD BE EQUIPPED WITH
    SELF CONTAINED BREATHING APPARATUS. INHALATION: MOVE CONSCIOUS
    PERSONS TO FRESH  AIR. QUICK REMOVAL FROM  CONTAMINATED AREA IS
    MOST IMPORTANT. MOVE UNCONSCIOUS PERSONS TO FRESH AIR AND GIVEN
    MOUTH-TO-MOUTH RESUSCITATION AND OXYGEN. GET MEDICAL ATTENTION
    IMMEDIATELY. FOR DERMAL CO NTACT OR FROSTBITE, FLUSH AFFECTED AREAS
    WITH LUKEWARM WATER. DO NOT USE HOT WATER. GET MEDICAL ATTENTION IF
    CRYOGENIC  "BURN" HAS RESULTED IN BLISTERING OR DEEP TISSUE
    FREEZING.

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

Extinguishing Media:NONFLAMMABLE, INERT.

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

Spill Release Procedures:LIQUID NITROGEN IS DELIVERED TO A CUSTOMER
    INTO STATIONARY VACUUM-JACKETED VESSELS AT THE CUSTOMER'S LOCATION
    OR IN PORTABLE VACUUM-KACKETED "LIQUID" CYLINDERS. STATIONARY
    CUSTOMER-SITE VESSELS SHOULD  BE OPERATED IN ACCORDANCE WITH THE
    MANUFACTURER'S & LIQUID AIR CORPORATION'S INSTRUCTIONS. DO NOT
    ATTEMPT TO REPAIR, ADJUST, OR IN ANY WAY MODIFY THE OPERATION OF
    THESE VESSELS. IF THERE IS A MALFUNC

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

Handling and Storage Precautions:LIQUID NITROGEN CYLINDERS SHOULD BE
    USED ONLY IN WELL-VENTILATED AREAS, IN ACCORDANCE WITH
    MANUFACTURER'S AND LIQUID AIR CORP INSTRUCTIONS. CYLINDERS MUST
    ALWAYS BE KEPT IN AN UPRIGHT POSITION. SPECIA LIZED HAND TRUCKS ARE
    NEEDED FOR THEIR MOVEMENT. "1ST IN 1ST OUT" INVENTORY SYSTEM SHOULD
    BE USED.
Other Precautions:LIQUIFIED GAS CYLINDERS SHOULD NOT BE REFILLED EXCEPT
    BY QUALIFIED PRODUCERS OF THESE PRODUCTS. SHIPMENT OF A COMPRESSED
    GAS CONTAINER WHICH HAS NOT BEEN FILLED BY THE OWNER OR WITH HIS
    (WRITTEN) CONS ENT IS A VIOLATION OF FEDERAL LAW (49CFR). SEE CGA
    SAFETY BULLETIN SB-2 AND CGA PAMPHLETS P-9,P-12,  P-14.

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

Respiratory Protection:POSITIVE PRESSURE AIR LINE WITH MASK OR SELF
    CONTAINED BREATHING APPARATUS SHOULD BE AVAILABLE FOR EMERGENCY
    USE.
Ventilation:PROVIDE LOCAL EXHAUST VENTILATION TO PREVENT ACCUMULATION
    OF HIGH CONCENTRATIONS SO AS TO REDUCE THE OXYGEN LEVEL IN THE AIR
    TO LESS THAN 18 MOLAR PERCENT.
Protective Gloves:WEAR LOOSE FITTING, INSULATED GLOVES.
Eye Protection:WEAR SAFETY GOGGLES OR GLASSES PLUS FACE SHIELD.
Other Protective Equipment:SAFETY SHOES.
Supplemental Safety and Health
DO NOT STORE CYLINDERS IN SUB-SURFACE OR CLOSED (POORLY VENTILATED)
    AREAS. NITROGEN GAS CAN CAUSE SUFFOCATION WITHOUT WARNING.
