Storage and Handling

Because of its high acute toxicity, trimethyltin chloride should be handled using the "basic prudent practices" of Chapter 5.C, supplemented by additional precautions for work with compounds of high acute toxicity (Chapter 5.D). Other alkyltin compounds should be handled using the "basic prudent practices" of Chapter 5.C.


In the event of skin contact, immediately wash with soap and water and remove contaminated clothing. In case of eye contact, promptly wash with copious amounts of water for 15 min (lifting upper and lower lids occasionally) and obtain medical attention. 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.


Excess trimethyltin chloride or other organotin compound and waste material containing this substance should be placed in an appropriate container, clearly labeled, and handled according to your institution's waste disposal guidelines. For more information on disposal procedures, see Chapter 7 of this volume.
