Reactivity AlertsHighly Flammable
Reactivity Profile · 1 item
Chlorosilanes, such as TRICHLORO(CHLOROMETHYL)SILANE, 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.
Air and Water ReactionsHighly flammable. Reacts vigorously with water to form hydrogen chloride (hydrochloric acid)
(Non-specific -- Methyl Trichlorosilane) Move container from fire area if you can do it without risk. Do not get water inside container. Cool containers that are exposed to flames with water from the side until well after fire is out. Stay away from ends of tanks. Withdraw immediately in case of rising sound from venting safety device or any discoloration of tank due to fire.
First Aid · 1 item
Signs and Symptoms of Acute Trichloro (Chloromethyl) Silane Exposure: Signs and symptoms of acute ingestion of trichloro (chloromethyl) silane may be severe, and include increased salivation, intense thirst, difficulty swallowing, chills, pain, and shock. Oral, esophageal, and stomach burns are common. Vomitus generally has a coffee-ground appearance. The potential for circulatory collapse is high following ingestion of trichloro (chloromethyl) silane. Acute inhalation exposure may result in sneezing, choking, laryngitis, dyspnea (shortness of breath), respiratory tract irritation, and chest pain. Bleeding of nose and gums, ulceration of the nasal and oral mucosa, pulmonary edema, chronic bronchitis, and pneumonia may also occur. If the eyes have come in contact with trichloro (chloromethyl) silane, irritation, pain, swelling, corneal erosion, and blindness may result. Dermatitis (red, inflamed skin), severe burns, pain, and shock generally follow dermal exposure.
Exposure Control and Personal Protection · 1 item
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].
Nonfire Spill ResponseCaution : Extremely flammable; may spontaneously ignite. Avoid sources of extreme heat or ignition including sparks or fire. Trichloro (chloromethyl) silane will liberate hydrochloric acid upon contact with water.
Disposal Methods · 1 item
SRP: At the time of review, criteria for land treatment or burial (sanitary landfill) disposal practices are subject to significant revision. Prior to implementing land disposal of waste residue (including waste sludge), consult with environmental regulatory agencies for guidance on acceptable disposal practices.
