=============  Composition/Information on Ingredients  =============

Name:ARGON
CAS:7440-37-1
RTECS #:CF2300000
ACGIH TLV:SIMPLE ASPHYXIANT

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

Routes of Entry: Inhalation:YES  Skin:NO  Ingestion:NO
Reports of Carcinogenicity:NTP:NO    IARC:NO	OSHA:NO
Health Hazards Acute and Chronic:ARGON IS ODORLESS & NONTOXIC, BUT MAY
    PRODUCE SUFFOCATION BY DILUTING THE CONCENTRATION OF OXYGEN IN AIR
    BELOW LEVELS NECESSARY TO SUPPORT LIFE. DEATH MAY RESULT FROM
    ERRORS IN JUDGMENT. AT LOW OXYGEN  CONCENTRATIONS
    UNCONSCIOUSNESS/DEATH MAY OCCUR IN SECONDS W/OUT WARNING. EXTENSIVE
    TISSUE DAMAGE/BURNS CAN RESULT.
Explanation of Carcinogenicity:NONE
Effects of Overexposure:EXPOSURE TO OXYGEN-DEFICIENT ATMOSPHERES MAY
    PRODUCE DIZZINESS, NAUSEA, VOMITING, LOSS OF CONSCIOUSNESS & DEATH.
    DEATH MAY RESULT FROM ERROS IN JUDGMENT, CONFUSION, LOSS OF
    CONSCIOUSNESS, WHICH PREVEN TS SELF-RESCUE.

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

First Aid:MOVE PERSONS SUFFERING FROM LACK OF OXGYEN TO AREAS W/NORMAL
    ATMOSPHERES. GIVE ASSISTED RESPIRATION & SUPPLEMENTAL OXYGEN IF
    VICTIM IS NOT BREATHING. IF CRYOGENIC LIQUID OR COLD BOIL-OFF GAS
    CONTACTS  A WORKER'S SKIN, EYES, OR TISSUES; FLOOD OR SOAK W/TEPID
    WATER (

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

Fire Fighting Procedures:DON'T ENTER AREAS WHERE THE OXYGEN
    CONCENTRATION IS BELOW 19.5% UNLESS PROVIDED W/A SCBA OF AIRLINE
    RESPIRATOR.
Unusual Fire/Explosion Hazard:CYLINDERS EXPOSED TO HIGH HEAT OR FLAME
    MAY VENT RAPIDLY.

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

Spill Release Procedures:FLUSH LIQUID ARGON SPILL W/WATER TO DISPERSE.
    VENTILATE ENCLOSED AREAS TO PREVENT FORMATION OF OXYGEN-DEFICIENT
    ATMOSPHERE CAUSED BY THE EVAPORATION OF LIQUID ARGON OR THE RELEASE
    OF GASEOUS ARGON. AR GON IS HEAVIER THAN AIR & MAY COLLECT IN LOW
    AREAS

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

Handling and Storage Precautions:STORE LIQUID CONTAINERS AND CYLINDERS
    IN WELL VENTILATED AREAS. KEEP CYLINDERS AWAY FROM SOURCES OF HEAT.
    DON'T STORE IN HEAVY TRAFFIC AREAS.
Other Precautions:KEEP VALVE CAPS ON CYLINDERS NOT CONNECTED FOR USE.
    SEGREGATE FULL/EMPTY CYLINDERS. STORE AWAY FROM COMBUSTIBLES. USE A
    CHECK VALVE TO PREVENT BACKFLOW INTO STORAGE CONTAINER. AVOID
    DRAGGING/ROLLING/S LIDING CYLINDER. USE SUITABLE HAND TRUCK

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

Respiratory Protection:USE SCBA IN OXYGEN-DEFICIENT ATMOSPHERE.
    RESPIRATORS WILL NOT FUNCTION. USE MAY RESULT IN ASPHYXIATION.
Ventilation:NATURAL OR MECHANICAL WHERE GAS OR VAPORS ARE PRESENT.
    LOCAL EXHAUST/MECHANICAL: AS NECESSARY.
Protective Gloves:LOOSE FITTING OF IMPERMEABLE MATERIAL
Eye Protection:SAFETY GLASSES, CHEMICAL GOGGLES
Supplemental Safety and Health
PREVENT ENTRAPMENT OF LIQUID IN CLOSED SYSTEMS. COMPRESSED GAS
    CYLINDERS CONTAIN ARGON AT EXTREMELY HIGH PRESSURE & SHOULD BE
    HANDLED W/CARE. USE A PRESSURE REDUCING REGULATOR WHEN CONNECTING
    TO LOWER  PRESSURE PIPING SYSTEMS. SECURE CYLINDERS WHEN IN USE.
    NEVER USE DIRECT FLAME TO HEAT A COMPRESSED GAS CYLINDER.

====================  Disposal Considerations  ====================

Waste Disposal Methods:ALLOW TO EVAPORATE IN A WELL VENTILATED OUTDOOR
    AREA REMOTE FROM WORK AREAS. DON'T ATTEMPT TO DISPOSE OF RESIDUE IN
    COMPRESSED GAS CYLINDERS. RETURN CYLINDERS TO MFG W/RESIDUAL
    PRESSURE, CYLINDER VALV E TIGHTLY CLOSED & VALVE CAPS IN PLACE.
