When heated, when heated, it emits smoke and emits toxic hydrogen chloride gas; when heated, it produces toxic chloride fumes

Suffocating odor

Decomp by water with much heat into silicic acid and hydrochloric acid.

Fumes in air. Decomposed by water or moist air with much heat generated and forms silicic acid and hydrochloric acid [Merck 11th ed. 1989]. Silicon tetrachloride reacts vigorously with water to generate gaseous HCl. Based on a scenario where the chemical is spilled into an excess of water (at least 5 fold excess of water), half of the maximum theoretical yield of Hydrogen Chloride gas will be created in 0.38 minutes. Experimental details are in the following: "Development of the Table of Initial Isolation and Protective Distances for the 2008 Emergency Response Guidebook", ANL/DIS-09-2, D.F. Brown, H.M. Hartmann, W.A. Freeman, and W.D. Haney, Argonne National Laboratory, Argonne, Illinois, June 2009.

Chlorosilanes

Water-Reactive

Chlorosilanes, such as SILICON TETRACHLORIDE, 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. This material is incompatible with alkali metals and dimethyl sulfoxide.

The vapour is heavier than air.
