    CYL WITH WATER SPRAY UNTIL COOL,   THEN MOVE CONTAINERS AWAY FROM
    FIRE AREA IF W/O RISK. SHUT OFF LEAK IF W/O RISK.
Unusual Fire/Explosion Hazard:GAS MIXTURE CANNOT CATCH FIRE. CONTAINER
    MAY RUPTURE DUE TO HEAT OF FIRE. MOST  CONTAINERS ARE PROVIDED WITH
    A PRESSURE RELIEF DEVICE DESIGNED TO VENT CONTENTS.

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

Spill Release Procedures:EVACUATE ALL PERSONNEL FROM AREA. USE S.C.B.A.
       WHERE NEEDED. SHUT OFF CYLINDER IF W/O RISK. VENT-ILATE AREA OF

    DESIGNED TO WITH- STAND PRESSURES TO BE ENCOUNTERED.  STORE/USE
    WITHADEQUATE VENTILATION.GAS CAN CAUSE RAPID SUFFOCATI
Other Precautions:CLOSE VALVE WHEN NOT IN USE AND WHEN EMPTY. DO NOT
    STRIKE ARC ON CYLINDER. THE  DEFECT PRODUCED BY AN ARC BURN COULD
    LEAD TO CYLINDER RUPTURE. DO NOT GROUND CYLNEVER WORK ON A
    PRESSURIZED SYSTEM.

=============  Exposure Controls/Personal Protection  =============

Respiratory Protection:USE RESPIRABLE FUME RESPIRATOR OR AIR SUPPLIED
    RESPIRATOR WHEN WORKING IN CON-  FINED SPACE OR WHERE LOCAL EXHAUST
    OR VENTILATION DOES NOT KEEP EXPOSURE BELOW  TLV.
Ventilation:USE ENOUGH VENTILATION, LOCAL EXHAUSE OR BOTH, TO KEEP THE 
    FUMES & GASES BELOW TLV'S IN WORKERS BREATHING ZONE.
Protective Gloves:WELDING GLOVES
