VENTILATION:             USE GENERAL OR LOCAL EXHAUST VENTILATION TO MEET
                         TLV REQUIREMENTS.

RESPIRATORY PROTECTION:  RESPIRATORY PROTECTION REQUIRED IF AIRBORNE
                         CONCENTRATION EXCEEDS TLV.  AT CONCENTRATIONS UP
                         TO 1000 PPM, A CHEMICAL CARTRIDGE RESPIRATOR WITH
                         ORGANIC VAPOR CARTRIDGE IS RECOMMENDED.  ABOVE
                         THIS LEVEL, A SELF-CONTAINED BREATHING APPARATUS
                         IS RECOMMENDED.

EYE/SKIN PROTECTION:     SAFETY GOGGLES, UNIFORM, APRON, NEOPRENE GLOVES
                         ARE RECOMMENDED.
