Guidance on Safe Use
Administrative data
First-aid measures
Emergency measure - Eyes: Rinse with running water for at least 15 minutes. Seek
immediate medical attention.
Emergency measure - Skin: Remove contaminated clothing, wash affected parts with
water. Seek medical attention.
Emergency measure - Ingestion: The substance can form an obstructing bolus in the stomach.
Do not induce vomitting and do not give anything by mouth.
Seek immediate medical attention.
Fire-fighting measures
Recommended extinguishing agent: Products of combustion may include nitrogen and silicon
oxides. Wear a self-contained breathing apparatus and
protective clothing when fighting fires. Alcohol/universal
foam, carbon dioxide or dry powder are suitable
extinguishing agents.
Accidental release measures
Emergency measures in case of spillage: Soak up spill with absorbent material and dispose of by
incineration. Wear suitable protective clothing.
Handling and storage
Handling: Avoid contact with skin and clothing, use goggles and PVC
gloves. Avoid inhalation of vapour (use a self-contained
breathing apparatus for high vapour concentrations). Wash
thoroughly after handling.
Storage: No special precautions, keep container closed.

Stability and reactivity
Danger other than fire: Silane Y-9492 hydrolyses in contact with water to give
methanol and a siloxane gel.
Disposal considerations
Industry - Possibility of recovery/recycling: Recovery is not economically feasible
Industry - Possibility of neutralisation: Hydrolysis with water (minimum 10:1) to methanol and
siloxane. A large excess of water may result in a solution
of monomeric hexasilanol.
Industry - Possibility of destruction: controlled discharge: Not recommended
Industry - Possibility of destruction - incineration: Incinerate at a suitable licensed site. Waste gas scrubbing
to remove nitrogen oxides is recommended.
Industry - Possibility of destruction - water purification: Not recomended
Public at large - Possibility of recovery/recycling: The substance will not enter the public domain
