II | [Safety Profile]
Poison by inhalation
and intraperitoneal routes. Moderately toxic
by ingestion. A skin and severe eye irritant.
A very dangerous fire hazard when exposed
to heat, flame, or oxidizers; will react with
water or steam to produce heat and toxic
and corrosive fumes; can react vigorously
with oxidizing materials. To fight fire, use
CO2, dry chemical. When heated to decom position it emits highly toxic fumes of Cl
and phosgene. See also

Hazard Information | Back Directory | [General Description]
A colorless fuming liquid with a pungent odor. Flash point 57°F. Boiling point 211.1°F (99.5°C). Vapor and liquid may cause burns. Denser than water. Vapors heavier than air. | [Reactivity Profile]
Chlorosilanes, such as ETHYLTRICHLOROSILANE, 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. | [Hazard]
Flammable, dangerous fire risk, may form
explosive mixture with air. A strong irritant. | [Health Hazard]
Vapor and liquid cause burns. Do not inhale or expose eyes to vapor. Vapor may damage eyes even if not immediately painful. | [Potential Exposure]
Used in the manufacture of silicone
polymers. | [Fire Hazard]
Trichloroethylsilane may form explosive mixtures with air. Its vapors are heavier than air and may travel a considerable distance to a source of ignition and flash back. Form toxic and corrosive fumes including phosgene when heated to decomposition and hydrochloric acid in presence of water. Will react with water or steam to produce heat and toxic and corrosive fumes. Will react vigorously with oxidizing materials. Unstable, avoid decomposing heat. | [First aid]
If this chemical gets into the eyes, remove any
contact lenses at once and irrigate immediately for at least
15 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 to 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. | [Shipping]
UN1196 Ethyltrichlorosilane, Hazard Class: 3;
Labels: 3-Flammable liquid, 8-Corrosive material.
| [Incompatibilities]
A strong reducing agent. 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,
and 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.
