Dichlorosilane (CAS NO.4109-96-0) is used in semiconductor manufacturing, especially the epitaxy process as the silicon source.It is also used in the electronics industry in the poly-silicon epitaxial growth, as well as chemical vapor deposition silicon dioxide and silicon nitride.
TOXIC; may be fatal if inhaled or absorbed through skin. Contact with gas or liquefied gas may cause burns, severe injury and/or frostbite. Fire will produce irritating, corrosive and/or toxic gases. Runoff from fire control may cause pollution.

Reported in EPA TSCA Inventory.
Flammable; may be ignited by heat, sparks or flames. May form explosive mixtures with air. Vapors from liquefied gas are initially heavier than air and spread along ground. Vapors may travel to source of ignition and flash back. Some of these materials may react violently with water. Cylinders exposed to fire may vent and release toxic and flammable gas through pressure relief devices. Containers may explode when heated. Ruptured cylinders may rocket. Runoff may create fire or explosion hazard.
