Chlorodimethylsilane: Does not have an individual approval but may be used under an appropriate group standard

Reacts violently with water evolving heat and hydrogen chloride gas; Liquid and vapor highly corrosive to skin and respiratory tissue; [CAMEO] Reacts with water producing flammable gases that may ignite spontaneously; Causes burns; Inhalation may cause corrosive injuries to upper respiratory tract and lungs; [Sigma-Aldrich MSDS]

Chlorosilanes, such as DIMETHYLCHLOROSILANE, are compounds in which silicon is bonded to from one to four chlorine atoms with other bonds to hydrogen and/or alkyl groups. Chlorosilanes react with water, moist air, or steam to produce heat and toxic, corrosive fumes of hydrogen chloride. They may also produce flammable gaseous H2. They can serve as chlorination agents. Chlorosilanes react vigorously with both organic and inorganic acids and with bases to generate toxic or flammable gases.

TIH (Toxic Inhalation Hazard) - Term used to describe gases and volatile liquids that are toxic when inhaled. Some are TIH materials themselves, e.g., chlorine, and some release TIH gases when spilled in water, e.g., chlorosilanes. [ERG 2016].
