OXYGEN

CAS: 7782-44-7

RTECS: RS2060000

LD50 LC50 Mixture:NOT PROVIDED
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 HIGH ER PRESSURE INCREASES THE
LIKELIHOOD OF ADVERSE EFFECTS WITH A SHORTER TIME PERIOD. BREATHING
PURE OXYGEN UNDER PRESSURE MAY CAUSE LUNG DAMAGE AND ALSO CNS
EFFECTS RESULTING IN DIZZINESS, POOR COORDIN ATION, TINGLING
SENSATION, VISUAL DISTURBANCES, MUSCULAR TWITCHING,
UNCONSCIOUSNESS, CONVULSIONS, PROLONGATION OF ADAPTION TO DARKNESS
AND REDUCED PERIPHERAL VISION. EYE/SKIN/INGESTION: TISSUE FREEZE ,
BURNS. CHRONIC: NO DATA FOUND.
Explanation of Carcinogenicity:OXYGEN IS NOT LISTED AS A CARCINOGEN OR
POTENTIAL CARCINOGEN BY NTP, IARC, OR OSHA SUBPART Z.
Effects of Overexposure: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
DIZZINESS, POOR COORDINATION, TINGLING SENSATION, VISUAL
DISTURBANCES, MUSCULAR TWITCHING, UNCONSCIOUSNESS, CONVULSIONS,
PROLONGATION OF ADAPTION TO DARKNESS AND REDUCED PERIPH ERAL
VISION. EYE/SKIN/INGESTION: TISSUE FREEZE, BURNS.
Medical Cond Aggravated by Exposure:PATIENTS WITH CHRONIC OBSTRUCTIVE
PULMONARY DISEASE RETAIN CARBON DIOXIDE ABNORMALLY. IF OXYGEN IS
ADMINISTERED, THEIR BREATHING IS DEPRESSED AND CARBON DIOXIDE
RAISES TO A DANGEROUS LEVEL.

First Aid:INHALATION: MOVE VICTIM TO FRESH AIR. CALL A PHYSICIAN. THE
PHYSICIAN SHOULD BE ADVISED THAT THE VICTIM HAS BEEN EXPOSED TO A
HIGH CONCENTRATION OF OXYGEN. RESCUE PERSONNEL SHOULD BE AWARE OF
THE EXTR EME FIRE HAZARDS ASSOCIATED WITH OXYGEN-ENRICHED
ATMOSPHERES. EYE CONTACT: IN CASE OF EYE CONTACT, IMMEDIATELY FLUSH
WITH WATER FOR AT LEAST 15 MINUTES. SEE A PHYSICIAN, PREFERABLY AN
OPHTHALMOLOGIST, IMMEDIATELY. SKIN CONTACT: IMMEDIATELY WARM
FROSTBITE AREA WITH WARM WATER (NOT TO EXCEED 105F). NEVER USE DRY
HEAT. CALL A PHYSICIAN. INGESTION: NONE.

Flash Point:NONFLAMMABLE
Extinguishing Media:OXYGEN IS NON FLAMMABLE BUT WILL SUPPORT
COMBUSTION. USE EXTINGUISHING MEDIA APPROPRIATE FOR SURROUNDING
FIRE. USE WATER SPRAY TO IMMEDIATELY COOL CONTAINERS
Fire Fighting Procedures:IF POSSIBLE, STOP THE FLOW OF OXYGEN WHICH IS
SUPPORTING THE FIRE. MOVE CYLINDERS FROM FIRE AREA IF POSSIBLE. A
NIOSH-APPROVED AIR-SUPPLIED RESPIRATOR OR SELF-CONTAINED BREATHING
APPARATUS MAY BE REQ UIRED FOR RESCUE WORKERS.
Unusual Fire/Explosion Hazard:OXYGEN VIGOROUSLY ACCELERATES COMBUSTION.
OXYGEN MAY FORM EXPLOSIVE COMPOUNDS WHEN EXPOSED TO COMBUSTIBLE
MATERIALS OR OIL, GREASE, AND OTHER HYDROCARBON MATERIALS.
PRESSURE IN A CONTAINER CAN BUILD UP DUE TO HEAT AND IT MAY
RUPTURE IF PRESSURE RELIEF DEVICES SHOULD FAIL TO FUNCTION.

Spill Release Procedures:EVACUATE UNNECESSARY PERSONNEL FROM AFFECTED
AREA. SHUT OFF SOURCE OF OXYGEN IF POSSIBLE. REMOVE SOURCES OF HEAT
AND IGNITION. SEPARATE COMBUSTIBLE FROM LEAK. INCREASE VENTILATION.
PREVENT LIQUID OXYG EN FROM CONTACTING GREASE, OIL, ASPHALT AND
OTHER COMBUSTIBLES. SPRAY WATER TO INCREASE RATE OF VAPORIZATION.
DO NOT SPRAY WATER DIRECTLY AT LEAK. AVOID CONTACT WITH LIQUID
OXYGEN OR COLD GAS.
Neutralizing Agent:NOT RELEVANT

Handling and Storage Precautions:STORE AND USE WITH ADEQUATE
VENTILATION. DO NOT STOE IN CONFINED SPACES. IF CYLINDER IS NOT
CONNECTED TO A SYSTEM, IT MUST BE SECURED AND CAPPED. STORE AWAY
(20 FEET) FROM COMBUSTIBLE/FLAMMABLE MATERI ALS. STORAGE AREA
TEMPERATURES SHOULD NOT EXCEED 125F (52C). SEPARATE FULL FROM EMPTY
CYLINDERS.
Other Precautions:DO NOT DRAG, SLIDE, ROLL CYLNDER. USE HAND TRUCK TO
MOVE CYLNDR. USE PRESSURE REDUCING REGULATOR WHEN CONNECTING
CYLINDER TO LOWER PRESSURE PIPING/SYSTEM. DO NOT HEAT CYLNDER TO
INCREASE FLOW RATE. US E CHECK VALVE OR TRAP TO PREVENT BACKFLOW.
OXYGEN IS NOT TO BE USED AS A SUBSTITUTE FOR COMPRESSED A IR.

Respiratory Protection:NONE 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(>21%)
Protective Gloves:LOOSE FITTING THERMAL ISULATED OR LEATHER GLOVES.
Eye Protection:FULL FACE SHIELD AND SAFETY GLASSES ARE RECOMMENDED.
Other Protective Equipment:SAFETY SHOES WHEN HANDLING CYLINDERS. LONG
SLEEVE SHIRTS AND TROUSERS WITHOUT CUFFS.
Work Hygienic Practices:PERSONNEL WHO HAVE BEEN EXPOSED TO HIGH
CONCENTRATIONS OF OXYGEN SHOULD STAY IN A WELL-VENTILATED OR OPEN
AREA FOR 30 MINUTES.

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 DET ACHMENT AND BLINDNESS. RETINAL DAMAGE MAY
ALSO OCCUR IN ADULTS EXPOSED TO 100% OXYGEN FOR EXTENDED PERIODS
(24 TO 48 HR). AT TWO OR MORE ATMOSPHERES, CENTRAL NERVOUS SYSTEM
(CNS) TOXICITY OCCURS. AT T HREE ATMOSPHERES, CNS TOXICITY OCCURS
IN LESS THAN TWO HOURS, AND AT SIX ATMOSPHERES IN ONLY A FEW
MINUTES.
