=======================  First Aid Measures  =======================

First Aid:INHAL: PROMPT MEDICAL ATTENTION MANDATORY IN CASES OF
    OVEREXPOSURE. ASSIST VICTIMS TO FRESH AIR. QUICK REMOVAL TO FRESH
    AIR IS MOST IMPORTANT. ARTIFICIAL RESUSCITATION OR OXYGEN IF
    NEEDED.  KEEP WARM	& QUIET. SKIN: WASH WITH SOAP & WATER. IN ALL
    CASES, GET MEDICAL ATTENTION.

Upper Limits:80-85 *
Extinguishing Media:CARBON DIOXIDE, DRY CHEMICAL. * PURE ACETYLENE CAN
    IGNITE BY DECOMP >15 PSI,UEL 100% IF IGNIT INTENSE.
Fire Fighting Procedures:STOP FLOW OF GAS SUPPLY. ALLOW FUEL TO CONSUME
    ITSELF. USE WATER SPRAY TO COOL ADJACENT AREAS. KEEP PERSONNEL
    AWAY, HEATED/BURNING CYLINDERS CAN RUPTURE.

Other Precautions:**USE HAND TRUCK TO MOVE.USE PRESSURE REDUCING
    REGULATOR WHEN REMOVING GAS FROM CYLINDER.DONT ALLOW FREE GAS TO
    >15 PSI @ 70F.DONT HEAT CYLINDER TO INCREASE FLOW.USE CHECK VALVE
    OR TRAP IN DISCHARGE L INE TO PREVENT HAZARDOUS BACK FLOW.***
