OXYGEN

CAS: 7782-44-7

RTECS: RS2060000

Reports of Carcinogenicity:NTP:NO IARC:NO OSHA:NO
Health Hazards Acute and Chronic:OXYGEN VIGOROUSLY ACCELERATES
COMBUSTION. CONTACT WITH ALL FLAMMABLE MATERIALS SHOULD BE
AVOIDED. SOME MATERIALS WHICH ARE NOT FLAMMABLE IN AIR WILL BURN
IN PURE OXYGEN OR OXYGEN-ENRICHED ATMOSPHERE S.
Effects of Overexposure:BREATHING HIGH CONCENTRATIONS (GREATER THAN 75
MOLAR PRECENT) CAUSES SYMPTOMS OF HYPEROXIA WHICH INCLUDES CRAMPS,
NAUSEA, DIZZINESS, HYPOTHERMIA, AMBLYOPIA, RESPIRATORY
DIFFICULTIES, BRADYCARDIA, FAIN TING SPELLS, AND CONVULSIONS
CAPABLE OF LEADING TO DEATH. FOR ADDITIONAL INFORMATION ON
HYPEROXIA, SEE COMPRESSED GAS ASSOCIATION'S PAMPHLET P-14.

First Aid:PROMPT MEDICAL ATTENTION IS MANDATORY IN ALL CASES OF
OVEREXPOSURE TO OXYGEN. RESCUE PERSONNEL SHOULD BE COGNIZANT OF
EXTREME FIRE HAZARD ASSOCIATED WITH OXYGEN-RICH ATMOSPHERES.
CONSCIOUS PERSONS S HOULD BE ASSISTED TO AN UNCONTAMINATED AREA AND
BREATHE FRESH AIR. THEY SHOULD BE KEPT WARM AND QUIET. THE
PHYSICIAN SHOULD BE INFORMED THAT THE VICTIM IS EXPERIENCING (HAS
EXPERIENCED) HYPEROXIA. UNCONSCIOUS PERSONS SHOULD BE MOVED TO AN
UNCONTAMINATED AREA AND GIVEN ASSISTED RESPIRATION. WHEN BREATHING
HAS BEEN RESTORED, TREATMENT SHOULD BE AS ABOVE. CONTINUED
TREATMENT SHOULD BE SYMPTOMATI C AND SUPPORTIVE.

Extinguishing Media:COPIOUS QUANTITIES OF WATER FOR FIRES WITH OXYGEN
AS THE OXIDIZER.
Fire Fighting Procedures:IF POSSIBLE, STOP THE FLOW OF OXYGEN WHICH IS
SUPPORTING THE FIRE. IF CYLINDERS ARE INVOLVED IN A FIRE, SAFELY
RELOCATE OR KEEP COOL WITH WATER SPRAY.
Unusual Fire/Explosion Hazard:VIGOROUSLY ACCELERATES COMBUSTION.

Spill Release Procedures:EVACUATE ALL PERSONNEL FROM AFFECTED AREA.
USE APPROPRIATE PROTECTIVE EQUIPMENT. IF LEAK IS IN USER'S
EQUIPMENT, BE CERTAIN TO PURGE PIPING WITH AN INERT GAS PRIOR TO
ATTEMPTING REPAIRS. IF LEAK IS IN CONTAINER OR CONTAINER VALVE,
CONTACT YOUR CLOSEST SUPPLIER LOCATION OR CALL THE EMERGENCY
TELEPHONE NUMBER LISTED HEREIN.

Handling and Storage Precautions:USE ONLY IN WELL-VENTILATED AREAS.
VALVE PROTECTION CAPS AND VALVE OUTLET THREADED PLUGS MUST REMAIN
IN PLACE UNLESS CONTAINER IS SECURED WITH VALVE OUTLET PIPED TO USE
POINT. PROTECT CYLINDERS FROM PHYSICAL DAMAGE. STORE IN COOL,
DRY, WELL-VENTILATED AREA AWAY FROM HEAVILY TRAFFICKED AREAS.
Other Precautions:OXYGEN SHOULD NOT BE USED AS A SUBSTITUTE FOR
COMPRESSED AIR IN PNEUMATIC EQUIPMENT SINCE THIS TYPE GENERALLY
CONTAINS FLAMMABLE LUBRICANTS. EQUIPMENT TO CONTAIN OXYGEN MUST BE
"CLEANED FOR OXYGEN SE RVICE." SEE COMPRESSED GAS ASSOCIATION
PAMPHLET G-4.1.

Ventilation:LOCAL EXHAUST: TO PREVENT ACCUMULATION ABOVE 25 MOLAR
PERCENT.
Protective Gloves:AS REQUIRED;ANY MATERIAL
Eye Protection:SAFETY GOGGLES OR GLASSES
Other Protective Equipment:SAFETY SHOES, SAFETY SHOWER
Supplemental Safety and Health
OXYGEN VIGOROUSLY ACCELERATES COMBUSTION. CONTACT WITH ALL FLAMMABLE

Toxicological Information:THE PROPERTY IS THAT OF HYPEROXIA WHICH LEADS
TO PNEUMONIA. CONCENTRATIONS BETWEEN 25 AND 75 MOLAR PERCENT
PRESENT A RISK OF INFLAMMATION OF ORGANIC MATTER IN THE BODY.
OXYGEN IS NOT LISTED IN THE I ARC, NTP OR BY OSHA AS A CARCINOGEN
OR POTENTIAL CARCINOGEN. PERSONS IN ILL HEALTH WHERE SUCH ILLNESS
WOULD BE AGGRAVATED BY EXPOSURE TO OXYGEN SHOULD NOT BE ALLOWED TO
WORK WITH OR HANDLE THIS PRODU CT.
