INDIVIDUALS EXPOSED FOR LONG PERIODS TO OXYGEN AT HIGH PRESSURE &
ALL WHO EXHIBIT OVERT OXYGEN TOXICITY SHOULD HAVE OPHTHALMOLOGIC
EXAMINATIONS.

Extinguishing Media:USE MEDIA APPROPRIATE FOR SURROUNDING FIRE. WATER
IS THE PREFERRED EXTINGUISHING MEDIA FOR CLOTHING FIRES.
Fire Fighting Procedures:EVACUATE ALL PERSONNEL FROM DANGER AREA. COOL

Spill Release Procedures:SHUT OFF LEAK IF W/OUT RISK. VENTILATE AREA OF
LEAK OR MOVE LEAKING CONTAINER TO WELL-VENTILATED AREA. REMOVE ALL
FLAMMABLE MATERIALS FROM VICINITY. IF THERE IS A LEAK, CLOSE
CYLINDER VALVE/BLOW DOWN SYSTEM BY VENTING TO SAFE PLACE/REPAIR
THE LEAK.
