|CAS #: 818-08-6|
| UN #: 3146
|EC Number: 212-449-1
|ACUTE HAZARDS||PREVENTION||FIRE FIGHTING|
|FIRE & EXPLOSION||Combustible. Gives off irritating or toxic fumes (or gases) in a fire. Finely dispersed particles form explosive mixtures in air.||NO open flames. Closed system, dust explosion-proof electrical equipment and lighting. Prevent deposition of dust. Prevent build-up of electrostatic charges (e.g., by grounding).||Use water spray, powder, carbon dioxide.|
|AVOID ALL CONTACT! IN ALL CASES CONSULT A DOCTOR!|
|Inhalation||Headache. Confusion.||Use local exhaust or breathing protection.||Fresh air, rest. Refer for medical attention.|
|Skin||Redness. Pain. Further see Inhalation.||Protective gloves.||Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention .|
|Eyes||Redness. Pain.||Wear face shield or eye protection in combination with breathing protection.||First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.|
|Ingestion||See Inhalation.||Do not eat, drink, or smoke during work. Wash hands before eating.||Rinse mouth. Give a slurry of activated charcoal in water to drink. Refer for medical attention .|
|SPILLAGE DISPOSAL||CLASSIFICATION & LABELLING|
|Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Do NOT let this chemical enter the environment. Sweep spilled substance into covered containers. If appropriate, moisten first to prevent dusting. Carefully collect remainder. Then store and dispose of according to local regulations.||

|The substance is very toxic to aquatic organisms. The substance may cause long-term effects in the aquatic environment. This substance does enter the environment under normal use. Great care, however, should be taken to avoid any additional release, for example through inappropriate disposal.|
|Molecular mass can vary because Dibutyltin oxide can occur in a partial polymerized form, on which its stability depends.
Insufficient data are available on the effect of this substance on human health, therefore utmost care must be taken.
