ARGON, LAR (LIQUID ONLY)

CAS: 7440-37-1

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 ODORLESS AND NONTOXIC, BUT
MAY PRODUCE SUFFOCATION BY DILUTING THE CONCENTRATION OF OXYGEN
IN AIR BELOW LEVELS NECESSARY TO SUPPORT LIFE. EXTENSIVETISSUE
DAMAGE OR BURNS CAN RESULT FROM E XPOSURE TO LIQUID ARGON OR COLD
ARGONVAPORS.
Effects of Overexposure:EXPOSURE TO OXYGEN-DEFICIENT ATMOSPHERES MAY
PRODUCE DIZZINESS, NAUSEA, VOMITINGLOSS OF CONSCIOUSNESS, AND
DEATH. DEATH MAY RESULT FROM ERRORS IN JUDGMENT, CON-FUSION, OR
LOSS OF CONSCIOUSNESS WHICH P REVENTS SELF-RESCUE. AT LOW
OXYGENCONCENTRATIONS UNCONSCIOUSNESS AND DEATH MAY OCCUR IN SECONDS
WITHOUT WARNING.

First Aid:PERSONS SUFFERING FROM LACK OF OXYGEN SHOULD BE MOVED TO
AREAS WITH NORMAL ATMOSCPR AND SUPPLEMENTAL OXYGEN SHOULD BE GIVEN
IF VICTIM IS NOT BREATHING. IF CRYO-GENIC LIQUID OR COLD BOIL-OFF
GAS CONTAC TS A WORKER'S SKIN OR EYES,FROZEN TISSUESHOULD BE
FLOODED OR SOAKED WITH TEPID WATER, NOT HOT. CRYOGENIC BURNS WHICH
RE-SULT IN BLISTERING OR DEEPER TISSUE FREEZING SHOULD BE SEEN
PROMPTLY BY A PHYSIC

Spill Release Procedures:AVOID SKIN CONTACT. FLUSH LIQUID ARGON SPILL
WITH WATER TO DISPERSE. VENTILATE ENCLOSED AREAS TO PREVENT
FORMAITON OF OXYGEN-DEFICIENT ATMOSPHERE CAUSED BY EVAPORATION
OF LIQUID ARGON OR RELEASE OF GASEOUS ARGON. ARGON IS HEAVIER
THANAIR.

Handling and Storage Precautions:USE/STORE IN WELL VENTILATED AREAS.
KEEP CYLINDERSAWAY FROM HEAT SOURCES AND COMBUSTIBLE MATERIALS.
SEGREGATE FULL/EMPTY CYLINDERS.
Other Precautions:AVOID EXPOSURE TO AREAS WHERE SALT OR OTHER CORROSIVE
CHEMICALS ARE PRESENT. PREVENT ENTRAPMENT OF LIQUID IN CLOSED
SYSTEMS. USE A CHECK VALVE TO PREVENT BACKFLOW INTO STORAGE
CONTAINER.

Respiratory Protection:USE SELF-CONTAINED BREATHING APPARATUS IN
OXYGEN-DEFICIENT ATMOSPHERE. CAUTION! RESPIRATORS WILL
NOT FUNCTION. USE MAY RESULT IN ASPHYXIATION.
Ventilation:NATURAL OR CHEMICAL WHERE GAS OR VAPORS ARE PRESENT.
Protective Gloves:LEATHER
Eye Protection:SAFETY GLASSES OR CHEMICAL GOGGLES.
Supplemental Safety and Health
VENTS SHOULD BE SITUATED TO AVOID HIGHER THAN NORMAL CONCENTRATION OF
ARGON IN WORK AREAS.
