Reports of Carcinogenicity:NTP:NO    IARC:NO	OSHA:NO
Health Hazards Acute and Chronic:TARGET ORGANS: RESPIRATORY SYSTEM,
    SKIN. ACUTE: THE MOST SIGNIFICANT HAZARD ASSOCIATED WITH THIS GAS
    IS INHALATION OF OXYGEN-DEFICIENT ATMOSPHERES, SYMPTOMS OF OXYGEN
    DEFICIENCY INCLUDE RESPIRATORY DI FFICULTY, RINGING IN EARS,
    HEADACHES, SHORTNESS OF BREATH, WHEEZING, HEADACHE, DIZZINESS,
    INDIGESTION, NAUSEA, AND AT HIGH CONCENTRATIONS, UNCONSCIOUSNESS OR
    DEATH MAY OCCUR. THE SKIN OF A VICTIM OF O VER-EXPOSURE MAY HAVE A
    BLUE COLOR. CONTACT WITH CRYOGENIC LIQUID OR RAPIDLY EXPANDING
    GASES (WHICH ARE RELEASED UNDER HIGH PRESSURE) MAY CAUSE FROSTBITE.
    CHRONIC: THERE ARE CURRENTLY NO KNOWN ADVERSE  HEALTH EFFECTS.
Explanation of Carcinogenicity:NITROGEN IS NOT FOUND ON THE FOLLOWING
    LISTS: FEDERAL OSHA Z LIST, NTP. CAL/OSHA, IARC; THEREFORE IT IS
    NOT CONSIDERED TO BE, NOR SUSPECTED TO BE A CANCER-CAUSING AGENT BY
    THESE AGENCIES.
Effects of Overexposure:THE FOLLOWING EFFECTS ASSOCIATED WITH VARIOUS
    LEVELS OF OXYGEN ARE AS FOLLOWS: CONCENTRATION: 12-16%OXYGEN:
    BREATHING AND PULSE RATE INCREASED, MUSCULAR COORDINATION SLIGHTLY
    DISTURBED. 10-14% OXYGEN:  EMOTIONAL UPSET, ABNORMAL FATIGUE,
    DISTURBED RESPIRATION. 5-10% OXYGEN: NAUSEA AND VOMITING, COLLAPSE
    OR LOSS OF CONSCIOUSNESS. BELOW 5%: CONVULSIVE MOVEMENTS, POSSIBLE
    RESPIRATORY COLLAPSE  AND DEAT H. CONTACT OF LIQUID WITH SKIN CAN
    LEAD TO SEVERE CRYOGENIC BURNS OR DERMATITIS. CONTACT OF LIQUID
    WITH EYES CAN CAUSE PAIN, REDNESS, SEVERE CRYOGENIC BURNS,
    BLINDNESS.
Medical Cond Aggravated by Exposure:PRE-EXISTING RESPIRATORY CONDITIONS
    MAY BE AGGRAVATED BY OVER-EXPOSURE TO LIQUID NITROGEN.

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

First Aid:RESCUERS SHOLD NOT ATTEMPT TO RETRIEVE VICTIMS OF EXPOSURE TO
    LIQUID NITROGEN WITHOUT ADEQUATE PERSONAL PROTECTIVE EQUIPMENT. AT
    A MINIMUM, SELF-CONTAINED BREATHING APPARATUS SHOULD BE WORN.
    REMOVE VI CTIM TO FRESH AIR, AS QUICKLY AS POSSIBLE. TRAINED
    PERSONNEL SHOULD ADMINISTER SUPPLEMENTAL OXYGEN AND/OR
    CARDIO-PULMONARY RESUSCITATION, IF NECESSARY. FOR EYE CONTACT,
    FLUSH WITH WATER FOR 15 MINUTES . SEE OPHTHALMOLOGIST IMMEDIATELY.
    FOR SKIN FROSTBITE, USE WARM WATER (105F/40C). NEVER HOT WATER.
    SEEK IMMEDIATE MEDICAL ATTENTION.

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

Extinguishing Media:NON-FLAMMABLE, INERT CRYOGENIC LQUID. USE
    EXTINGUISHING MEDIA APPROPRIATE FOR SURROUNDING FIRE.
Fire Fighting Procedures:STRUCTURAL FIRE-FIGHTERS MUST WEAR
    SELF-CONTAINED BREATHING APPARATUS AND FULL PROTECTIVE EQUIPMENT.
    IF POSSIBLE, REMOVE CONTAINERS FROM FIRE AREA OR COOL WITH WATER.
    DO NOT DIRECT WATER SPRAY AT THE  CONTAINER VENT. EVACUATE AREA.
    OTHER INFORMATION FOR PREPLANNING CAN BE FOUND IN NORTH AMERICAN
    EMERGENCY RESPONSE BOOK.
Unusual Fire/Explosion Hazard:NITROGEN DOES NOT BURN; HOWEVER,
    CONTAINERS, WHEN INVOLVED IN FIRE, MAY RUPTURE OR BURST IN THE HEAT
    OF THE FIRE. LIQUID NITROGEN WHEN ACCIDENTALLY RELEASED WILL
    VAPORIZE RAPIDLY, FORMING AN OXYGEN DE FICIENT VAPOR CLOUD.
    EVACUATE THIS VAPOR CLOUD AREA. VISIBILITY MAY BE OSCURED IN ITS
    VAPOR CLOUD.

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

Spill Release Procedures:CLEAR THE AFFECTED AREA AND ALLOW THE LIQUID
    TO EVAPORATE AND THE GAS TO DISSIPATE. AFTER THE GAS IS FORMED,
    FOLLOW THE INSTRUCTIONS PROVIDED BELOW. ALTERNATIVELY. TO INCREASE
    THE RATE OF VAPORIZATION , SPRAY LARGE AMOUNTS OF WATER ON TO THE
    LEAK FROM AN UPWIND POSITION. IF THE AREA MUST BE ENTERED BY
    EMERGENCY PERSONNEL, SCBA, LEATHER OR INSULATED GLOVES, AND SAFETY
    SHOES MUST BE WORN.
Neutralizing Agent:NOT RELEVANT

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

Handling and Storage Precautions:CRYOGENIC CONTAINERS SHOULD BE STORED
    IN DRY, WELL-VENTILATED AREAS AWAY FROM SOURCES OF HEAT, IGNITION
    AND DIRECT SUNLIGHT. STORE CONTAINERS AWAY FROM HEAVILY TRAFFICKED
    AREAS AND EMERGENCY EXITS. PR OTECT CONTAINERS AGAINST PHYSICAL
    DAMAGE. CONTAINERS SHOULD BE STORED UPRIGHT AND BE FIRMLY SECURED.
Other Precautions:USE PIPING AND EQUIPMENT ADEQUATELY DESIGNED TO
    WITHSTAND PRESSURES AND TEMPERATURES TO BE ENCOUNTERED. USE A CHECK
    VALVE OR OTHER PROTECTIVE APPARATUS IN ANY LINE OR PIPING FROM THE
    CONTAINER TO PREV ENT REVERSE FLOW. TO PREVENT CRYOGENIC LIQUIDS OR
    COLD GAS FROM BEING TRAPPED, USE PRESSURE RELIEF D EVICE.

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

Respiratory Protection:MAINTAIN OXYGEN LEVELS ABOVE 19.5%IN THE
    WORKPLACE. USE SUPPLIED AIR RESPIRATORY PROTECTION IF OXYGEN LEVELS
    ARE BELOW 19.5% OR DURING EMERGENCY RESPONSE TO A RELEASE OF LIQUID
    NITROGEN. IF RESPIRATOR Y PROTECTION IS REQUIRED, FOLLOW THE
    REQUIREMENTS OF THE FEDERAL OSHA RESPIRATORY PROTECTION STANDARD(29
    CFR 1910.134),OR EQUILVALENT STATE STANDARDS.
Ventilation:USE WITH ADEQUATE VENTILATION. LOCAL EXHAUST VENTILATION IS
    PREFERRED, BECAUSE IT PREVENTS GAS DISPERSION INTO THE WORK PLACE
    BY ELIMINATING IT AT ITS SOURCE.
Protective Gloves:WEAR LOOSE-FITTING, THERMALLY INSULATED OR LEATHER
    GLOVES.
Eye Protection:FULL FACESHIELD AND SAFETY GLASSES ARE RECOMMENDED.
Other Protective Equipment:USE BODY PROTECTI0N APPROPRIATE FOR TASK.
    SAFETY SHOES ARE RECOMMENDED WHEN HANDLING CONTAINERS, AS WELL AS
    LONG SLEEVE SHIRTS AND TROUSERS
