The toxicity diminishes as the size of the alkyl groups increases. Organotin compounds have been shown to cause reproductive effects in laboratory animals. Flammability and Explosibility Not a significant fire hazard. Emits toxic fumes in fire. Reactivity and Incompatibility Trimethyltin chloride and other organotin halides react with water to produce hydrogen halides.
Organotin hydrides react with water to produce hydrogen gas, which is flammable and explosive.
In the event of skin contact, immediately wash with soap and water and remove contaminated clothing. If trimethyltin chloride or another organotin compound is ingested, obtain medical attention immediately. If large amounts of this compound are inhaled, move the person to fresh air and seek medical attention at once. In the event of a spill, sweep up the organotin compound or soak up with a spill pillow or absorbent material, place in an appropriate container, and dispose of properly. Respiratory protection may be necessary in the event of a large spill or release in a confined area.
