Hazard InformationBack Directory
[General Description]

A colorless fuming liquid with a pungent odor. Boiling point 135°F Flash point-18°F. Density 0.854 g/cm3. The vapor and liquid may cause burns. Vapors are heavier than air.
[Reactivity Profile]

TRIMETHYLCHLOROSILANE reacts vigorously and exothermically with water to produce hydrogen chloride.
[Health Hazard]

Similar to other silanes. Toxicity is rated high for inhalation, ingestion and local irritation. May cause death or permanent injury after a very short exposure to small quantities.
[Potential Exposure]

Trimethylchlorosilane is used as an intermediate to make silicone products, including lubricants
[First aid]

If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 30 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, get medical attention. If victim is conscious, administer water, or milk. Do not induce vomiting. Medical observation is recommended for 24-48 hours after breathing overexposure, as pulmonary edema may be delayed. As first aid for pulmonary edema, a doctor or authorized paramedic may consider administering a drug or other inhalation therapy.
[Fire Hazard]

Violent reaction with water. Toxic and irritating hydrogen chloride and phosgene may be formed in fires. Difficult to extinguish, re-ignition may occur. Flashback along vapor trail may occur. Containers may explode in fire. Vapor may explode if ignited in enclosed area. When heated to decomposition or on contact with acids or acid fumes, chloride fumes are emitted. Reacts with surface moisture, releasing hydrogen chloride, which will corrode common metals and form flammable hydrogen gas. Avoid contact with water; TRIMETHYLCHLOROSILANE readily hydrolyzes, liberating hydrochloric acid. Hazardous polymerization may not occur.
[Shipping]

UN1298 Trimethylchlorosilane, Hazard Class: 3; Labels: 3-Flammable liquid, 8-Corrosive material.
[Incompatibilities]

Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides. Chlorosilanes react vigorously with bases and both organic and inorganic acids generating toxic and/or flammable gases. Chlorosilanes react with water, moist air, or steam to produce heat and toxic, corrosive fumes of hydrogen chloride. They may also produce flammable gaseous hydrogen. Attacks metals in the presence of moisture. Vigorous reaction with aluminum powder.
[Waste Disposal]

Do not discharge into drains or sewers. Use a licensed disposal contractor to an approved landfill. Must be disposed properly by following package label directions or by contacting your local or federal environmental control agency, or by contacting your regional EPA office for guidance on acceptable disposal practices. The most favorable course of action is to use an alternative chemical product with less inherent propensity for occupational exposure or environmental contamination. Recycle any unused portion of the material for its approved use or return it to the manufacturer or supplier. Ultimate disposal of the chemical must consider: the material’s impact on air quality; potential migration in soil or water; effects on animal, aquatic, and plant life; and conformance with environmental and public health regulations.
