Respiratory Protection: GENERAL USE:NONE REQUIRED. EMERGENCY:USE SCBA OR
POSITIVE PRESSURE AIR LINE W/MASK & ESCAPE PACK IN AREAS WHERE OXYGEN
CONCENTRATION IS <19.5%.AIR PURIFYING RESPIRATORS WILL NOT PROVIDE
PROTECTION.
Ventilation: PROVIDE GOOD VENTI &/OR LOC EXHAU TO PREVENT ACCUMULATION OF
HI GAS CONC.OXY LEVELS IN WORKAREA SHOULD BE MONITOR,>19.5%
Protective Gloves: LEATHER WORK GLOVES FOR HNDLG. 
Eye Protection: SAFETY GLASSES.
