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
