ACCIDENTAL RELEASE MEASURE
SMALL SPILLS: Absorb with materials such as: cat litter, sawdust, vermiculite, Zorb-all. Collect in suitable and properly labeled
containers.
LARGE SPILLS: Dike area to contain spill. Recover spilled material if possible. See Section 13, Disposal Considerations for additional
information.
PERSONAL PRECAUTIONS: Use appropriate safety equipment. For additional information, refer to Section 8, Exposure Controls and
Personal Protection.
ENVIRONMENTAL PRECAUTIONS: Prevent from entering into soil, ditches, sewers, waterways and/or groundwater. See Section 12,
Ecological Information.

HANDLING AND STORAGE
HANDLING
GENERAL HANDLING: See Section 8, EXPOSURE CONTROLS AND PERSONAL PROTECTION.
VENTILATION: Provide general and/or local exhaust ventilation to control airborne levels below the exposure guidelines.
OTHER PRECAUTIONS: Spills of these organic materials on hot fibrous insulations may lead to lowering of the autoignition
temperatures possibly resulting in spontaneous combustion.
STORAGE:
121°C ( 250° F). Do not store in: galvanized steel.

EXPOSURE CONTROLS AND PERSONAL PROTECTION
EXPOSURE LIMITS
COMPONENT
EXPOSURE LIMITS
SKIN FORM
Propylene glycol
10mg/m3 TWA8 AIHA WEEL
Aerosol
50 ppm TWA8 AIHA WEEL
Total Particulate fume
In the Exposure Limits Chart above, if there is no specific qualifier (i.e., Aerosol) listed in the Form Column for a particular limit, the
listed limit includes all airborne forms of the substance that can be inhaled.
PERSONAL PROTECTION
RESPIRATORY PROTECTION: Atmospheric levels should be maintained below the exposure guideline.
PROTECTION: When respiratory protection is required for certain operations, use an approved air-purifying respirator. In dusty or
misty atmospheres, use an approved particulate respirator.
EYE PROTECTION: Use safety glasses.
OTHER PROTECTIVE EQUIPMENT: No precautions other than body-covering clothing should be needed. Use gloves chemically
resistant to this material.

10. STABILITY AND REACTIVITY
STABILITY/INSTABILITY: Thermally stable at recommended temperatures and pressures.
CONDITIONS TO AVOID: Product can oxidize at elevated temperatures. Generation of gas during decomposition can cause pressure
in closed systems.
INCOMPATIBLE MATERIALS: Avoid contact with: Strong acids. Strong bases. Strong oxidizers.
THERMAL DECOMPOSITION: Decomposition products depend upon temperature, air supply and the presence of other materials.
Decomposition products can include and are not limited to: Aldehydes. Alcohols. Ethers.
HAZARDOUS POLYMERIZATION: Will not occur
