OXYGEN

CAS: 7782-44-7

RTECS: RS2060000

LD50 LC50 Mixture:NOT GIVEN
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 OXYGEN AT HIGHE R PRESSURES INCREASES THE
LIKELIHOOD OFADVERSE EFFECTS WITH A SHORTER TIME PERIOD. BREATHING
PURE OXYGEN UNDER PRESSURE MAY CAUSE LUNG DAMAGE AND ALSO CENTRAL
NERVOUS SYSTEM EFFECTS RESULTING IN DIZZ INESS, POOR COORDINATION,
TINGLING SENSATION, VISUAL AND HEARING DISTURBANCES,MUSCULAR
TWITCHING, UNCONSIOUSNESS AND CONVULSIONS. BREATHING OXYGEN UNDER
PRESSURE MAY CAUSE PROLONGATION TO DARKNESS AND REDUCED PERIPHERAL
VISION.
Explanation of Carcinogenicity:OXYGEN IS NOT LISTED AS A CARCINOGEN OR
POTENTIAL CARCINOGEN BY NTP, IARC, OR OSHA SUBPART Z.
Effects of Overexposure:SYMPTOMS INCLUDE 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 T WO HOURS, AND AT SIX ATMOSPHERES IN
ONLYA FEW MINUTES.
Medical Cond Aggravated by Exposure:PATIENTS WITH CHRONIC OBSTRUCTIVE
PULMONARY DISEASE RETAIN CARBON DIOXIDE ABNORMALITY. IF OXYGEN IS
ADMINISTERED TO THEM, RAISING THE OXYGEN CONCENTRATION IN THE BLOOD
DEPRESSES THEIR BREATHING.

First Aid:INHALATION-MOVE VICTIM TO FRESH AIR OR IF IN ELEVATED
PRESSURES REDUCES OXYGEN PRESSURES TO 1 ATMOSPHERE. CALL A
PHYSICIAN. THE PHYSICIAN SHOULD BE ADVISED THAT THE VICTIM HAS BEEN
EXPOSED TO A HIGH C ONCENTRATION OF OXYGEN. NO TREATMENT ISREQUIRED
IN THE ABSENCE OF SYMPTOMS OR HIGH PRESSURE EXPOSURE. EYE/SKIN: NOT
APPLICABLE.

Flash Point:NONFLAMMABLE
Lower Limits:NOT GIVEN
Upper Limits:NOT GIVEN
Extinguishing Media:OXYGEN IS NONFLAMMABLE BUT WILL SUPPORT COMBUSTION.
USE EXTINGUISHING MEDIA APPROPIATE FOR SURROUNDING FIRE.
Fire Fighting Procedures:EVACUSTE ALL PERSONNEL FROM DANGER AREA. IF
POSSIBLE, SHUT OFF FLOW OF OXYGEN WHICH IS SUPPORTING THE FIRE.
IMMEDIATELY COOL CONTAINERS WITH WATER SPRAY FROM MAXIMUM DISTANCE.
WHEN COOL MOVE CYLINDER S FROM FIRE AREA, IF POSSIBLE WITHOUT RISK.
Unusual Fire/Explosion Hazard:OXYGEN VIGOROUSLY ACCELERATES COMBUSTION.
FIRE RESISTANT CLOTHING MAY BURN AND OFFER NO PROTECTION IN OXYGEN
RICH ATMOSPHERES. OXYGEN MAY FORM EXPLOSIVE COMPOUNDS WHEN EXPOSED
TO COMBUSTIBLE MATERIALS OR OIL, GREASE AND OTHER HYDROCARBON
MATERIALS. IF CYLINDERS IN A FIRE, SAFELY RELOCATE / KEEP COOL WITH
WATER.

Spill Release Procedures:EVACUATE PERSONNEL FROM AFFECTED AREA. SHUT
OFF SOURCE OF OXYGEN IF POSSIBLE. INCREASE VENTILATION TO RELEASE
AREA.. PERSONNEL WHO HAVE BEEN EXPOSED TO HIGH CONCENTRATIONS OF
OXYGEN SHOULD STAY IN A W ELL-VENTILATED OR OPEN AREA FOR 30
MINUTES BEFORE GOING INTO A CONFINED SPACE OR NEAR AT IGNITION
SOURCE.
Neutralizing Agent:NONE SPECIFIED BY MANUFACTURER.

Handling and Storage Precautions:CYLINDERS SHOULD BE STORED UPRIGHT IN
A WELL-VENTILATED, SECURE AREA, PROTECTED FROM THE WEATHER. STORAGE
AREA TEMPERATURE SHOULD NOT EXCEED 125F AND AREA SHOULD BE FREE OF
COMBUSTIBLE MATERIALS. STOR AGE SHOULD BE AWAY FROM HEAVILY
TRAVELSAREAS AND EMERGENCY EXISTS. USE IN VENTED AREA.
Other Precautions:DON'T DRAG,SLIDE,ROLL CYLNDR. USE HAND TRUCK TO MOVE
CYLNDR.USE PRESSR REDUCING REGULTR WHEN CONNECTING CYLINDER TO
LOWER PRESSURE (<3000PSIG) PIPING/SYSTEM.DON'T HEAT CYLNDR TO
INCREASE FLOW RATE. US E CHECK VALVE OR TRAP (PREVENT BACKFLOW)

Respiratory Protection:NONE NORMALLY REQUIRED. EMERGENCY: USE SCBA DO
TO POSSIBILITY OF FIRE WHEN CONCENTRATIONS EXCEED 23%.
Ventilation:PROVIDE VENTILATION AND/OR LOCAL EXHAUST TO PREVENT
ACCUMULATION OF HIGH CONCENTRATIONS OF GAS (>23%)
Protective Gloves:WORK GLOVES ARE RECOMMENDED.
Other Protective Equipment:SAFETY SHOES WHEN HANDLING CYLINDERS.
CLOTHING EXPOSED TO HIGH CENCENTRATIONS MAY RETAIN OXYGEN 30 MIN OR
LONGER AND BECOME A POTENTIAL FIRE HAZARD. STAY AWAY FROM IGNITION
SOURCES.
Work Hygienic Practices:WASH HANDS THOROUGHLY WITH SOAP AND WATER
BEFORE EATING, DRINKING, SMOKING OR USING TOILET FACILITIES.
Supplemental Safety and Health
WHEN USED IN WELDING AND CUTTING READ AND UNDERSTAND THE MANUFACTURERS
INSTRUCTIONS AND THE PRECAUTIONARY LABEL ON THE PRODUCTS. NEVER
STRIKE AN ARC ON A COMPRESSED GAS CYLINDER OR MAKE A CYLINDER A P
ART OF AN ELECTRICAL CIRCUIT.

Toxicological Information:AT ATMOSPHERIC CONCENTRATIONS AND PRESSURES,
OXYGEN POSES NO TOXICITY HAZARDS. PREMATURE INFANTS EXPOSED TO HIGH
CONCENTRATIONS MAY SUFFER DELAYED RETINAL DAMAGE WHICH CAN PROGRESS
TO RETINAL DETACHME NT AND BLINDNESS. RETINAL DAMAGE MAY ALSO OCCUR
IN ADULTS EXPOSED TO 100% OXYGEN FOR EXTENDED PERIODS (24 TO 48
HRS)
