DIFFICULTIES, BRADYCARDIA, FAINTING SPELLS AND CONVULSIONS CAPABLE
OF LEADING TO DEATH.
Medical Cond Aggravated by Exposure:NONE SPECIFIED BY MANUFACTURER.

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 AND
QUIET. UNCONSCIOUS PERSONS SHOULD BE MOVED TO FRESH AIR AND GIVEN
ASSISTED RESPIRATION. TREATMENT SHOULD BE SYMPTOMATIC AND
SUPPORTIVE.

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:VIGOROUSLY ACCELERATES COMBUSTION.
CONTACT WITH EASILY OXIDIZABLE ORGANIC/COMBUSTIBLE MATERIALS MAY
RESULT IN IGNITION, VIOLENT COMBUSTION OR EXPLOSION.

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 CLOSEDSPACES.
Neutralizing Agent:NONE

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

Respiratory Protection:NOT RELEVANT
