Reports of Carcinogenicity:NTP:NO    IARC:NO	OSHA:NO
Health Hazards Acute and Chronic:ACUTE- BREATHING HIGH CONCENTRATIONS
    (GREATER THAN 75 MOLAR %) CAUSES SYMPTOMS OF HYPEROXIA WHICH
    INCLUDE CRAMPS, NAUSEA, DIZZINESS, HYPOTHERMIA, RESPIRATORY
    DIFFICULTIES, FAINTING SPELLS & CONVULSION S CAPABLE OF LEADING TO

Explanation of Carcinogenicity:OXYGEN IS NOT LISTED AS A CARCINOGEN BY
    THE IARC, NTP OR OSHA.
Effects of Overexposure:BREATHING HIGH CONCENTRATIONS (GREATER THAN 75
    MOLAR %) CAUSES SYMPTOMS OF HYPEROXIA WHICH INCLUDE CRAMPS, NAUSEA,
    DIZZINESS, HYPOTHERMIA, RESPIRATORY DIFFICULTIES, FAINTING SPELLS &
    CONVULSIONS CAPAB LE OF LEADING TO DEATH. CONCENTRATIONS BETWEEN 25

=======================  First Aid Measures  =======================

First Aid:PROMPT MEDICAL ATTENTION IS MANDATORY IN ALL CASES OF
    OVEREXPOSURE TO OXYGEN. RESCUE PERSONNEL SHOULD BE AWARE OF EXTREME
    FIRE HAZARD ASSOCIATED WITH OXYGEN-RICH ATMOSPHERES. CONSCIOUS
    PERSONS SHOULD  BE MOVED TO FRESH AIR. THEY SHOULD BE KEPT WARM &
    QUIET. UNCONSCIOUS PERSONS SHOULD BE MOVED TO FRESH AIR & GIVEN
    ASSISTED RESPIRATION. TREATMENT SHOULD BE SYMPTOMATIC & SUPPORTIVE.

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

Flash Point:NON-FLAMMABLE
Extinguishing Media:WATER SPRAY, CO2, FOAM/DRY CHEMICAL. WATER SPRAY
    MAY BE USED TO KEEP FIRE EXPOSED CONTAINERS COOL.
Fire Fighting Procedures:WEAR NIOSH-APPROVED SELF-CONTAINED BREATHING
    APPARATUS. MOVE CONTAINERS AWAY IF POSSIBLE. STOP FLOW OF OXYGEN
    WHICH IS SUPPORTING THE FIRE.
Unusual Fire/Explosion Hazard:ACCELERATES COMBUSTION. CONTACT WITH
    EASILY OXIDIZABLE ORGANIC/COMBUSTIBLE MATERIALS MAY RESULT IN
    IGNITION, VIOLENT COMBUSTION OR EXPLOSION.

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

Spill Release Procedures:EVACUATE PERSONNEL FROM AFFECTED AREA. USE
    APPROPRIATE PROTECTIVE EQUIPMENT. STOP LEAK IF YOU CAN DO IT
    WITHOUT RISK. ISOLATE AREA UNTIL GAS HAS DISPERSED. KEEP
    COMBUSTIBLE MATERIALS AWAY FROM SPILLED  MATERIAL. STAY UPWIND.
    VENTILATE CLOSED SPACES.
Neutralizing Agent:NONE

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

Handling and Storage Precautions:STORAGE- STORE IN COOL, DRY WELL
    VENTILATED AREA AWAY FROM HEAVILY TRAFFICKED AREAS & AWAY FROM
    FULL/EMPTY CYLINDERS CONTAINING FLAMMABLE PRODUCTS.
Other Precautions:STORE CYLINDERS IN UPRIGHT POSITION & FIRMLY SECURED.
    AVOID TEMPERATURES ABOVE 130F (54C). SEGREGATE FULL & EMPTY
    CYLINDERS. USE A "FIRST IN-FIRST OUT" INVENTORY SYSTEM. USE ONLY IN
    WELL VENTILATED AR EA. DO NOT DRAG, SLIDE OR ROLL CYLINDER.
