Routes of Entry: Inhalation:NO Skin:YES Ingestion:NO
Reports of Carcinogenicity:NTP:NO IARC:NO OSHA:NO
Health Hazards Acute and Chronic:OXYGEN IS NONTOXIC UNDER MOST
CONDITIONS OF USE AND IS NECESSARY TO SUPPORT LIFELIQUID OXYGEN OR
COLD GAS WILL FREEZE TISSUES AND CAN CAUSE SEVERE CRYOGENIC
(EXTREMELY LOW TEMPERATURE) BURNS.
Effects of Overexposure:OXYGEN IS NONTOXIC UNDER MOST CONDITIONS OF USE
AND IS NECESSARY TO SUPPORT LIFELIQUID OXYGEN OR COLD GAS WILL
FREEZE TISSUES AND CAN CAUSE SEVERE CRYOGENIC (EXTREMELY LOW
TEMPERATURE) BURNS.

First Aid:PARTIAL PRESSURE OF OXY IN EXCESS OF TWO ATMOS. MAY PRODUCE A
VARIETY OF CENTRALNERVOUS SYSTEM MANIFESTATIONS INCLUDING TINGLING
OF FINGERS & TOES, VISUAL AND HEARING DISTURBANCES,ABNORMAL
SENSATIONS ,IMPAIRED COORDINATION,CONFUSION, MUSCLETWITCHING, &
SEIZURES RESEMBLING THOSE OF EPILEPSY. INFANTS EXPOSED TO OXYGEN
LEVELS IN EXCESS OF 35-40% MAY SUFFER PERM. VISUAL IMPAIRMENT OR
BLINDNESS.

Fire Fighting Procedures:OXYGEN IS NONFLAMMABLE BUT SUPPORTS AND
VIGOROUSLY ACCELERATES COMBUSTION OF FLAMMABLES. TO FIGHT FIRES,
SHUT OFF SOURCES OF OXYGEN & FIGHT CONVENTIONALLY.
Unusual Fire/Explosion Hazard:OXYGEN IS NONFLAMMABLE BUT SUPPORTS &
VIGOROUSLY ACCELERATES COMBUSTION OF FLAM-MABLES.SOME MATERIALS
WHICH ARE NONCOMBUSTIBLE IN AIR WILL BURN IN OXYGEN.

Spill Release Procedures:PREVENT LIQ OXY FROM CONTACTING
GREASE,OIL,ASPHALTOR COMBUSTIBLES.VENTILATE AREA TO EVAPORATE &
DIS-PERSE OXY.FLUSH AREA WITH LARGE QUANTITIES OFWATERAVOID SMOKING
& CONTACT WITH SOURCES OF IGNITION AFTER EXPOSURE TO
CONCENTRATION OF HIGHLEVEL OXY.

Handling and Storage Precautions:STORE/USE IN WELL VENTILATED AREAS.
SEGREGATE FULL& EMPTY CYL. KEEP CYLINDERS AWAY FROM SOURCES OF
HEAT. STORE AWAY FROM COMBUSTIBLE MATERIALS.
Other Precautions:USE ONLY WITH EQUIP SPECIFICALLY DESIGNED AND CLEANED
FOR OXY SERVICE. OXYGEN ISNOT TO BE USED AS SUB FOR COMPRESSED AIR.
COMPRESSED GAS CYLINDERS SHOULD NOT BEREFILLED EXCEPT BY QUALIFIED
PRODUCERS O F COMPRESSED GASES.

Ventilation:PREVENT ACCUMULATION WITH NATURAL OR FORCED AIR.
Protective Gloves:LEATHER ARE SUGGESTED FOR LIQ & GAS.
Eye Protection:CHEMICAL GOGGLES OR SAFETY GLASSES.
Supplemental Safety and Health
VENTS SHOULD BE SITUATED TO AVOID HIGHER THAN NORMAL CONCENTRATIONS OF
OXYGEN INWORK AREAS. BREATHING PURE OXY AT ONE ATMOS MAY PRODUCE
COUGH AND CHEST PAINS WITHIN 8-24 HOURS. CONCENTRATIONS OF 60%
MAY PRODUCE THESE SYMPTOMS IN SEVERALDAYS. AT TWO ATMOSPHERES
SYMPTOMS OCCUR IN 2-3 HOURS.
