First Aid:NO EMERGENCY CARE ANTICIPATED. NOTE TO PHYSICIAN: AIRWAY
OBSTRUCTION IN HIGH OXYGEN TENSION MAY CAUSE ALVEOLAR COLLAPSE
FOLLOWING ABSORPTION OF OXYGEN. SIMILARLY, OCCLUSION OF EUSTACHIAN
TUBES MAY CAU SE RETRACTION OF EARDRUM, OBSTRUCTION OF PARANASAL
SINUSES, & VACUUM-TYPE HEADACHE. NEWBORN PREMATURE INFANTS EXPOSED
TO HIGH OXYGEN CONCENTRATIONS MAY SUFFER DELAYED RETINAL DAMAGE.
SEE SUPP.

Extinguishing Media:MIXTURES CONTAINING >23.5 % OXYGEN VIGOROUSLY
ACCELERATE COMBUSTION. USE MEDIA APPROPRIATE FOR SURROUNDING FIRE.
Fire Fighting Procedures:WATER IS THE PREFERRED EXTINGUISHING MEDIA FOR
CLOTHING FIRES. EVACUATE ALL PERSONNEL FROM DANGER AREA. COOL
CYLINDERS W/WATER SPRAY FROM MAXIMUM DISTANCE.
Unusual Fire/Explosion Hazard:SHUT OFF LEAK IF SAFE TO DO SO. OXYGEN
RICH MIXTURES VIGOROUSLY ACCELERATE COMBUSTION. CONTACT W/FLAMMABLE
MATERIALS MAY CAUSE FIRE OR EXPLOSION. SEE SUPP

Spill Release Procedures:SHUT OFF CYLINDER IF SAFE TO DO SO. VENTILATE
AREA OF LEAK OR MOVE LEAKING CYLINDER TO WELL-VENTILATED AREA. TEST
AREA, ESPECIALLY CONFINED AREAS, FOR SUFFICIENT OXYGEN CONTENT
PRIOR TO PERMITTING RE- ENTRY OF PERSONNEL.

Handling and Storage Precautions:SMOKING, FLAMES & ELECTRIC SPARKS IN
THE PRESENCE OF ENRICHED OXYGEN ATMOSPHERES ARE POTENTIAL EXPLOSION
HAZARDS. HIGH PRESSURE GAS.
Other Precautions:AVOID CONTACT W/OILS/GREASES/OTHER FLAMMABLE
MATERIALS. CLOSE VALVE WHEN NOT IN USE & WHEN EMPTY. USE PIPING &
EQUIPMENT ADEQUATELY DESIGNED TO WITHSTAND PRESSURES TO BE
ENCOUNTERED. NEVER WORK ON A P RESSURIZED SYSTEM.

Ventilation:MECHANICAL (GENERAL): ADEQUATE
Protective Gloves:PREFERRED FOR CYLINDER HANDLING
Eye Protection:AS REQUIRED
Other Protective Equipment:METATARSAL SHOES FOR CYLINDER HANDLING.
Supplemental Safety and Health
