Routes of Entry: Inhalation:YES Skin:NO Ingestion:NO
Health Hazards Acute and Chronic:BREATHING HIGH CONCENTRATIONS GREATER
THAN (75 MOLAR PERCENT) CAUSES SYMPTOMS OF HYPEROXIA INCLUDING
CRAMPS, NAUSEA, DIZZINESS, HYPOTHERMIA, AMBYLOPIA, RESPIRATORY
DIFFICULTIES, BRADYCARDIA, FAINTING SPELLS AND CONVULSIONS CAPABLE
OF LEADING TO DEATH. HYPEROXYIA CAN LEAD TO PNEUMONIA.

Effects of Overexposure:PERCENT PRESENT A RISK OF INFLAMMATION OF
ORGANIC MATTER IN THE BODY.

First Aid:PROMPT MEDICAL ATTENTION IS MANDATORY IN ALL CASES OF
OVEREXPOSURE TO OXYGEN. INHALE: CONSCIOUS PERSONS SHOULD BE
ASSISTED TO AN UNCONTAMINATED AREA AND INHALE FRESH AIR. THEY
SHOULD BE KEPT WARM AND QUIET. UNCONSCIOUS PERSONS SHOULD BE MOVED
TO AN UNCONTAMINATED AREA, GIVEN ASSISTED RESPIRATION. WHEN
BREATHING HAS BEEN RESTORED, TREATMENT SHOULD BE AS ABOVE.

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.
Unusual Fire/Explosion Hazard:VIGOROUSLY ACCELERATES COMBUSTION.

Spill Release Procedures:EVACUATE ALL PERSONNEL FROM AFFECTED AREA. USE
APPROPRIATE PROTECTIVE EQUIPMENT. LEAK IN EQUIP: PURGE PIPING WITH
AN INERT GAS PRIOR TO REPAIR.IF LEAK IS IN CONTAINER/CONTAINER
VALVE, CONTACT THE CLOS EST AIRCO LOCATION OR CALL CHEMTREC:
