Routes of Entry: Inhalation:YES Skin:YES Ingestion:NO
Reports of Carcinogenicity:NTP:NO IARC:NO OSHA:NO
Health Hazards Acute and Chronic:ARGON IS NONTOXIC BUT CAN ACT AS A
SIMPLE ASPHYXIANT BY DISPLACING THE AMOUNT OFOXYGEN IN THE AIR
NECESSARY TO SUPPORT LIFE.
Effects of Overexposure:MAY PRODUCE DIZZINESS, NAUSEA, VOMITING, LOSS
OF CONSCIOUSNESS, AND DEATH. DEATHMAY RESULT FROM ERRORS IN
JUDGMENT, CONFUSION, OR LOSS OF CONSCIOUSNESS WHICH PREVENTS
SELF-RESCUE. EXTENSIVE TISSUE D AMAGE OR BURNS CAN RSULT FROM
EXPOSURETO LIQUID ARGON OR COLD ARGON VAPORS.

First Aid:MOVE/ASSIST PERSON TO NORMAL ATMOSPHERES. RESCUERS SHOULD
WEAR S.C.B.A. IF PERSON IS NOT BREATHING GIVE CPR AND
SUPPLEMENTAL OXYGEN. IF CRYOGENIC LIQUID ORCOLD BOIL-OFF GAS
CONTACTS A WORKER'S SK IN OR EYES, FROZEN TISSUES SHOULD BEFLOODED
OR SOAKED WITH TEPID WATER, NOT HOT. CRYOGENIC BURNS WHICH RESULT
IN BLISTERING OR DEEPER TISSUE FREEZING SHOULD BE SEEN PROMPTLY
BY A PHYSICIAN.

Spill Release Procedures:FLUSH LIQUID ARGON SPILL WITH WATER TO
DISPERSE. VENTILATE ENCLOSED AREAS TO PREVENT FORMATION OF
OXYGEN-DEFICIENT ATMOSPHERE CAUSED BY THE EVAPOR- ATION OF LIQUID
ARGON OR THE RELEASE OF GASEOUS ARGON.ARGON HEAVIER THAN
AIR,COLLECTS LOW W/O VENT

Handling and Storage Precautions:PREVENT ENTRAPMENT OF LIQUID IN CLOSED
SYSTEMS.USE& STORE IN WELL VENTILATED AREA AWAY FROM SOURCES OF
HEAT. SEGREGATE FULL/EMPTY CYLINDERS.
Other Precautions:MATERIALS OF CONSTRUCTION MUST BE SELECTED FOR
COMPATIBILITY WITH EXTREMELY LOW TEMPERATURES.COMPRESSED GAS
CYLINDERS SHOULD NOT BE REFILLED EXCEPT BY QUALIFIEDPRODUCERS OF
COMPRESSED GASES.AVOID EXPO SURE TO AREAS WITH CORROSIVE CHEMICALS.

Respiratory Protection:USE SELF-CONTAINED BREATHING APPARATUS IN
OXYGEN-DEFICIENT ATMOSPHERE. CAUTION! RESPIRATORS WILL NOT
FUNCTION. USE MAY RESULT IN ASPHYXIATION.
Ventilation:NATURAL OR MECHANICAL WHERE GAS OR VAPORS ARE PRESENT.
VENTSTO BE HIGHER THAN NORMAL CONCENTRATION OF ARGON IN WORK AREA
Protective Gloves:LOOSE-FITTING GLOVES/IMPERMIABLE MATERIA
Eye Protection:SAFETY GLASSES OR CHEMICAL GOGGLES
