Reports of Carcinogenicity:NTP:NO    IARC:NO	OSHA:NO
Health Hazards Acute and Chronic:ACUTE-INHALATION-BREATHING 80% OR MORE
    OXYGEN AT ATMOSLPHERIC PRESSURE FOR MORE THAN A FEW HOURS MAY CAUSE
    NASAL STUFFINESS. BREATHING PURE OXYGEN UNDER PRESSURE MAY CAUSE

    CAUSE PROLONGATION OF ADAPTATION TO DARKNESS AND REDUCED PERIPHERAL
    VISION. SKIN CONTACT: NO HARM EXPECTED. EYE CONTACT: NO HARM
    EXPECTED. INGESTION: THIS PRODUCT  IS A GAS AT NORMAL TEMPERATURE
    AND PRESSURE. REPEATED (CHRONIC) OVEREXPOSURE: NO HARM EXPECTED.
Explanation of Carcinogenicity:OXYGEN IS NOT LISTED AS A CARCINOGEN BY
    THE IARC, NTP OR OSHA.
Effects of Overexposure:COUGH, SORE THROAT, CHEST PAIN, DIZZINESS,
    TINGLING SENSATION, MUSCULAR TWITCHING AND CONVULISONS. BREATHING

=====================  Fire Fighting Measures  =====================

Autoignition Temp:Autoignition Temp Text:NA
Lower Limits:NA
Upper Limits:NA
Extinguishing Media:OXIDIZING AGENT.VIGOROUSLY ACCELERATE COMBUSTION.
    USE MEDIA APPROPRIATE FOR SURROUNDING FIRE. WATER(E.G. SAFETY
    SHOWER) IS	PREFERRED EXTINGUISHING MEDIA FOR CLOTHING FIRES.
Fire Fighting Procedures:EVACUATE EVERYONE FROM DANGER AREA. 
    IMMEDIATELY DELUGE CYLINDERS WITH  WATER FROM MAXIMUM DISTANCE
    UNTIL COOL, THEN MOVE THEM AWAY FROM FIRE AREA IF WITHOUT RISK.
    SELF CONTAINED BREATHING APPARATUS M AY BE REQUIRED BY RESCUE
    WORKERS. ON-SITE FIRE BRIGADES MUST COMPLY WITH OSHA 29 CFR
    1910.156.
Unusual Fire/Explosion Hazard:OXYGEN ACCELERATES COMBUSTION WITH
    FLAMMABLE  MATERIALS. HEAT OF FIRE CAN BUILD PRESSURE IN CYLINDER &
    CAUSE  RUPTURE. CYLINDER SHOULD NOT BE SUBJECTED TO TEMP.> 125F.
    SMOKING, FLAMES, & ELECTRIC SPAR KS IN PRESENCE OF ENRICHED OXYGEN
    ATMOSPHERES ARE POTENTIAL EXPLOSION HAZARDS.

==================  Accidental Release Measures  ==================

Spill Release Procedures:STOP LEAK. VENTILATE AREA OR MOVE LEAKING
    CONTAINER TO WELL-VENTILATED AREA. REMOVE ALL FLAMMABLE MATERIALS.
    OXYGEN MUST NEVER BE PERMITTED TO STRIKE AN OILY SURFACE, GREASY
    CLOTHES, OR OTHER COMBUSTI BLE MATERIAL.
Neutralizing Agent:NONE

======================	Handling and Storage  ======================

Handling and Storage Precautions:STORE AND USE WITH ADEQUATE
    VENTILATION, AWAY FROM OIL, GREASE,OTHER HYDROCARBONS. SEPARATE
    OXYGEN CYLINDERS FROM FLAMMABLES. FIRMLY SECURE CYLINDERS
    UPRIGHT.SCREW VALVE CAP FIRMLY BY HAND. STORE WHER E TEMPERATURE
    WILL NOT EXCEED 125F. STORE FULL AND EMPTY CYLINDERS SEPARATELY.
Other Precautions:USE HAND TRUCK TO MOVE CYLINDERS; DO NOT DRAG, ROLL,
    SLIDE, OR DROP. NEVER APPLY FLAME OR LOCALIZED HEAT DIRECTLY TO
    CYLINDER. NEVER INSERT AN OBJECT INTO CAP OPENINGS; DOING SO MAY
    DAMAGE VALVE AND C AUSE A LEAK. USE AN ADJUSTABLE STRAP WRENCH TO
    REMOVE OVER-TIGHT OR RUSTED CAPS.

=============  Exposure Controls/Personal Protection  =============

Respiratory Protection:NONE REQUIRED UNDER NORMAL USE. HOWEVER,
    AIR-SUPPLIED RESPIRATORS ARE REQUIRED WHILE WORKING IN CONFINED
    SPACES WITH THIS PRODUCT. THE RESPIRATORY PROTECTION USE MUST
    CONFORM WITH OSHA RULES AS SPECIF IED IN 29 CFR 1910.134.
Ventilation:LOCAL EXHAUST TO PREVENT ACCUMULATION OF OXYGEN
    CONCENTRATION. MECHANICAL (GENERAL) IS ACCETABLE.
Protective Gloves:WORK GLOVES FOR HANDLING CYLINDERS OR WELDING GLOVES
    FOR WELDING(FREE OF OIL).
Eye Protection:SAFETY GLASSES OR GOGGLES PER (OSHA 29 CFR 1910.133).
Other Protective Equipment:METATARSAL SHOES FOR CYLINDER HANDLING.
    SELECT IN ACCORDANCE WITH OSHA 29 CFR 1910.132 AND 1910.133. FOR
    WELDING-WEAR HAND, HEAD AND BODY PROTECTION-APRONS,HATS,SHOULDER
    PROTECTION.
Work Hygienic Practices:WASH THOROUGHLY AFTER HANDLING CYLINDERS.
Supplemental Safety and Health
