Attacks many metals in presence of water releasing explosive hydrogen gas.

Readily hydrolyzed by moisture with liberation of hydrogen chloride|Dangerous fire risk /Silane compounds/|Organo-functional silanes are noted for their ability to bond organic polymer systems to inorganic substrates. /Silane compounds/|The reaction of organosilanes with halogens and halogen cmpd usually proceeds in good yield through cleavage of the Si--H bond and formation of the silicon-halogen bond. Reaction with fluorine, however, does not proceed satisfactorily because of cleavage of not only the Si--H but also C--Si and C--H bonds. Direct halogenation with chlorination, bromine, and iodine proceeds smoothly, however. /Organosilanes/

Reacts violently with water, steam, moist air, alcohols, acetone, light metals with generation of heat and combustible (H2) and corrosive (HCl) gases. On contact with air it gives off HCl gas. [Handling Chemicals Safely 1980. p. 924]. Phenyltrichlorosilane 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 2.6 minutes.

Chlorosilanes

Water-Reactive

Chlorosilanes, such as PHENYLTRICHLOROSILANE 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.
