Sweep up, then place into a suitable container for disposal. Avoid generating dusty conditions. Provide ventilation.
Stable under normal temperatures and pressures.
Strong acids, strong bases, strong oxidizing agents, 1-methylsilacyclopenta-2,-4diene.
Hydrogen cyanide, nitrogen oxides, carbon monoxide, carbon dioxide.
Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. To extinguish fire use water spray, dry chemical, carbon dioxide, or appropriate foam.
Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes.
Contact with metals may evolve flammable hydrogen gas.
Fire may produce irritating, corrosive and/or toxic gases.
May be fatal if swallowed. The toxicological properties of this substance have not been fully investigated. May cause central nervous system effects.
Inhalation of dust may cause respiratory tract irritation.
No information regarding skin irritation and other potential effects was found.
Dust may cause mechanical irritation.
If victim is conscious and alert, give 2-4 cupfuls of milk or water. Never give anything by mouth to an unconscious person. Get medical aid immediately.
Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid.
