SOL IN WATER

All containers, pipes, apparatus, installations, and structures used for the manufacture, storage, transport, or use of these substances must be of material resistant to corrosive substances or be protected by suitable coatings ... All containers or receptacles should be clearly labelled to indicate their contents and should bear the danger symbol for corrosives. /Corrosive substances/

Inflammable in case of open flame, high temperature, oxidant; produces toxic and corrosive chloride gas when heated or in water

Lower explosive limit: 3.4%; Upper explosive limit: > or = 9.5%

ACRID ODOR

Will react with water or steam to produce toxic and corrosive fumes; can react with oxidizing materials|Readily hydrolyzed with liberation of hydrochloric acid.|The reaction of organosilanes with halogens and halogen compounds 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/

Fumes in air. Highly flammable. Gives off HCl gas on contact with moist air. Reacts violently with water, steam, with generation of heat and combustible (H2) and corrosive (HCl) gases [Handling Chemicals Safely 1980 p. 924]. Propyltrichlorosilane 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 2.1 minutes. After mixing particular chemicals into water, there may be a delay of <1-10 minutes before gas generation may be observed. For this chemical, a 5 second induction time was observed.
