EXPOSURE CONTROLS/PERSONAL PROTECTION
ENGINEERING CONTROLS: Provide general and/or local exhaust ventilation to control
airborne levels below the exposure guidelines.
PERSONAL PROTECTIVE EQUIPMENT
EYE/FACE PROTECTION: Use safety glasses. Safety glasses should be sufficient for most
operations; however, for misty operations wear chemical goggles.
SKIN PROTECTION: Use gloves impervious to this material.
RESPIRATORY PROTECTION: Atmospheric levels should be maintained below the exposure
guideline. When respiratory protection is required for certain operations, use an approved air-
purifying respirator. In misty atmospheres, use an approved mist respirator.
EXPOSURE GUIDELINES: Propylene glycol: AIHA WEEL is 50 ppm total, 10 mg/m3 aerosol
only.
