OXYGEN

CAS: 7782-44-7

RTECS: RS2060000

LD50 LC50 Mixture:NONE SPECIFIED BY MANUFACTURER.
Routes of Entry: Inhalation:YES Skin:NO Ingestion:NO
Reports of Carcinogenicity:NTP:NO IARC:NO OSHA:NO
Health Hazards Acute and Chronic:INHALATION: BREATHING 80% OR MORE
OXYGEN AT ATMOSPHERIC PRESSURE FOR MORE THAN A FEW HOURS MAY CAUSE
NASAL STUFFINESS, COUGH, SORE THROAT, CHEST PAIN AND BREATHING
DIFFICULTY. BREATHING PURE OXYGEN UN DER PRESSURE MAY CAUSE LUNG
DAMAGE AND ALSO CENTRAL NERVOUS SYSTEM EFFECTS RESULTING IN
DIZZINESS, POOR COORDINATION, TINGLING SENSATION, VISUAL AND
HEARING DISTURBANCES, MUSCULAR TWITCHING, UNCONSCIO USNESS AND
CONVULSIONS. EYE, SKIN & INGESTION: TISSUE FREEZING AND SEVERE
CRYOGENIC BURNS ON CONTACT WITH LIQUID. NO ADVERSE EFFECT EXPECTED
FROM VAPOR.
Explanation of Carcinogenicity:NOT RELEVANT.
Effects of Overexposure:NO EVIDENCE OF ADVERSE EFFECTS FROM REPEATED
EXPOSURE AVAILABLE.
Medical Cond Aggravated by Exposure:PATIENTS WITH CHRONIC OBSTRUCTIVE
PULMONARY DISEASE RETAIN CARBON DIOXIDE ABNORMALLY. IF OXYGEN IS
ADMINISTERED TO THEM, RAISING THE OXYGEN CONCENTRATION IN THEIR
BLOOD CAN DEPRESS THEIR BREATHING.

First Aid:INGESTION: CALL MD IMMEDIATELY. INHALATION: MOVE TO FRESH
AIR. CALL PHYS. PHYS SHOULD BE ADVISED THAT VICTIM HAS BEEN EXPOSED
TO HIGH CONCENTRATION OF OXYGEN. RESCUE PERSONNEL SHOULD BE AWARE
OF EXTRE ME FIRE HAZARDS. EYES: IMMEDIATELY FLUSH W/WATER FOR 15
MINUTES. SEE A PHYS, PREFERABLY OPHTHALMOLOGIST, IMMEDIATELY. SKIN:
FOR EXPOSURE TO LIQUID, IMMEDIATELY WARM FROSTBITE AREA W/WARM
WATER. SUPPOR TIVE TREATMENT: IMMEDIATE SEDATION, ANTI-CONVULSIVE
IF NEEDED, & REST.

Autoignition Temp:Autoignition Temp Text:NONFLA
Lower Limits:NONFLAM
Upper Limits:NONFLAM
Extinguishing Media:MATERIAL IS NON FLAMMABLE. USE EXTINGUISHING MEDIA
APPROPRIATE FOR SURROUNDING FIRE.
Fire Fighting Procedures:NIOSH APPROVED SCBA & FULL PROTECTIVE
EQUIPMENT. EVACUATE ALL PERSONNEL FROM DANGER AREA. IF POSSIBLE,
SHUT OFF FLOW OF OXYGEN WHICH IS SUPPORTING FIRE. IMMEDIATELY COOL
CONTAINERS.
Unusual Fire/Explosion Hazard:OXIDIZING AGENT, VIGOROUSLY ACCELERATES
COMBUSTION. SOME MATERIALS WHICH ARE NONCOMBUSTIBLE IN AIR WILL
BURN IN PRESENCE OF OXYGEN ENRICHED ATMOSPHERE (>23%).
FIRE-RESISTANT CLOTHING MAY BURN AND OFFE R NO PROTECTION IN OXYGEN
RICH ATMOSPHERES. OXYGEN MAY FORM EXPLOSIVE COMPOUNDS WHEN EXPOSED
TO COMBUSTIBLE MATERIALS.

Spill Release Procedures:EVACUATE ALL UNNECESSARY PERSONNEL FROM
AFFECTED AREA. SHUT OFF SOURCE OF OXYGEN, IF POSSIBLE, SEPARATE
COMBUSTIBLES FROM THE LEAK. REMOVE SOURCES OF HEAT& IGNITION.
VENTILATE AREA OR REMOVE LEAKING C ONTAINER TO WELL-VENTILATED
AREA. IF POSSIBLE, PREVENT LIQUID OXYGEN FROM CONCENTRATING.
Neutralizing Agent:NONE SPECIFIED BY MANUFACTURER.

Handling and Storage Precautions:STORE & USE W/ADEQUATE VENTILATION. DO
NOT STORE IN CONFINED SPACE. CRYOGENIC CONTAINERS ARE EQUIPPED
W/PRESSURE RELIEF DEVICES TO CONTROL INTERNAL PRESSURE.
Other Precautions:ALL GAUGES, VALVES, REGULATORS, PIPING & EQUIPMENT TO
BE USED IN OXYGEN SERVICE SHOULD BE USED IN ACCORDANCE WITH CGA
PAMPHLET G-4.1 USE PIPING AND EQUIPMENT ADEQUATELY DESIGNED TO
WITHSTAND PRESSURES TO BE ENCOUNTERED. SOME METALS SUCH AS CARBON
STEEL MAY BECOME BRITTLE AT LOW TEMPERATURES AND WIL L EASILY
FRACTURE.

Respiratory Protection:GENERAL USE: NOT REQUIRED. EMERGENCY USE: USE
NIOSH APPROVED SCBA DUE TO POSSIBILTY OF FIRE WHEN CONCENTRATIONS
EXCEED 23%.
Ventilation:NATURAL OR MECHANICAL TO PREVENT OXYGEN-ENRICHED
ATMOSPHERES OVER 21% OXYGEN.
Protective Gloves:LOOSE FIT THERMAL INSULATED/LEATHER.
Eye Protection:SAFETY GLASSES.
Other Protective Equipment:SAFETY SHOES WHEN HANDLING CONTAINERS. LONG
SLEEVE SHIRTS & TROUSERS W/OUT CUFFS. ANSI APPROVED EYE WASH &
DELUGE SHOWER.
Work Hygienic Practices:GLOVES MUST BE CLEAN & FREE OF OIL & GREASE.

Toxicological Information:AT ATMOSPHERIC CONCENTRATION AND PRESSURE,
OXYGEN POSES NO TOXICITY HAZARDS. PREMATURE INFANTS EXPOSED TO
HIGH OXYGEN CONCENTRATIONS MAY SUFFER DELAYED RETINAL DAMAGE WHICH
CAN PROGRESS TO RETINAL DE TACHMENT AND BLINDNESS. RETINAL
DAMAGEMAY ALSO OCCUR IN ADULTS EXPOSED TO 100% OXYGEN FOR EXTENDED
PERIODS (24 TO 48 HR). AT TWO OR MORE ATMOSPHERES CNS TOXICITY
OCCURS ( NAUSEA, VOMITING, DIZZINESS OR VERTIGO, MUSCLE TWITCHING,
VISION CHANGES, AND LOSS OF CONSCIOUSNESS AND GENERALIZED
SEIZURES). AT THREE ATMOSPHERES, CNS TOXICITY OCCURS IN LESS THAN
TWO HOURS, AND AT SIX ATMOSPHERES ONLY MINUT ES.
