Containment/Clean up: Sections 13 and 15 of this MSDS provide information regarding certain federal and
state requirements. Clean up remaining materials from spill with suitable absorbant.
Clean area as appropriate since some silicone materials, even in small quantities, may
present a slip hazard. Final cleaning may require use of steam, solvents or detergents.
Observe all personal protection equipment recommendations described in Sections 5
and 8. Local, state, and federal laws and regulations may apply to releases and
disposal of this material, as well as those materials and items employed in the cleanup
of releases. You will need to determine which federal, state and local laws and
regulations are applicable.
Note: See section 8 for Personal Protective Equipment for Spills. Call Dow Corning Corporation, (517) 496-5900,
if additional information is required.
7. HANDLING AND STORAGE
Use with adequate ventilation. Traces of benzene (carcinogen) may form if heated in air above 300 F (149 C).
Provide ventilation to control vapor exposure within inhalation guidelines when handling at elevated temperatures.
Review the OSHA benzene regulation for detailed information on safe handling requirements. Use at high
temperatures may evolve or generate phenylheptamethylcyclotetrasiloxane, 2,6-cisdiphenylhexamethylcyclotetrasiloxane. Provide adequate ventilation to control within exposure guidelines.
Personnel should wear organic vapor respirators until workplace exposure levels have been determined. Do not
take internally. Avoid eye contact.
Use reasonable care and store away from oxidizing materials.
