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.

10.STABILITY AND REACTIVITY
CHEMICAL STABILITY: Thermally stable at typical use temperatures.
CONDITIONS TO AVOID: Avoid use temperatures above 450EF, 232EC. Product can degrade at elevated temperatures. Generation of gas during decomposition can cause pressure in closed systems.
INCOMPATIBILITY WITH OTHER MATERIALS: Avoid contact with oxidizing materials. Avoid contact with strong acids
HAZARDOUS DECOMPOSITION PRODUCTS: Hazardous decomposition products depend upon temperature, air supply and the presence of other materials.
HAZARDOUS POLYMERIZATION: Will not occur.
