Section 6: Accidental Release Measures
Small Spill: Absorb with an inert material and put the spilled material in an appropriate waste disposal.
Large Spill:
Absorb with an inert material and put the spilled material in an appropriate waste disposal. Finish cleaning by spreading water
on the contaminated surface and allow to evacuate through the sanitary system.
Section 7: Handling and Storage
Precautions:
Keep away from heat. Keep away from sources of ignition. Empty containers pose a fire risk, evaporate the residue under a
fume hood. Ground all equipment containing material. Do not breathe gas/fumes/ vapor/spray. Keep away from incompatibles
such as oxidizing agents, acids, alkalis.
Storage: Keep container tightly closed. Keep container in a cool, well-ventilated area.
Section 8: Exposure Controls/Personal Protection
Engineering Controls:
Provide exhaust ventilation or other engineering controls to keep the airborne concentrations of vapors below their respective
threshold limit value. Ensure that eyewash stations and safety showers are proximal to the work-station location.
Personal Protection:
Safety glasses. Lab coat. Gloves. No respiratory protection should be needed. Please note that these precautions are for
room temperature handling without aerosol/spray application. Use at elevated temperature or aerosol/spray applications
may require added precautions. For further information regarding aerosol inhalation toxicity, please refer to the guidance
document regarding the use of silicone-based materials in aerosol applications that has been developed by the silicone
industry (www.sehsc.com).
Personal Protection in Case of a Large Spill:
Splash goggles. Full suit. Boots. Gloves. No respiratory protection should be needed. Please note that these precautions are
for room temperature handling without aerosol/spray application. Use at elevated temperature or aerosol/spray applications
may require added precautions. For further information regarding aerosol inhalation toxicity, please refer to the guidance
document regarding the use of silicone-based materials in aerosol applications that has been developed by the silicone
industry (www.sehsc.com).
