Hydrolysis products of dibutyltin dichlorides:
The hydrolysis of di-s-butyltin dichloride yields similar products to those found for the di-n-butyl compound whereas the hydrolysis behaviour of di-t-butyltin dichloride is markedly different.
Distannoxanes are not found in the latter case but instead di-t-butyltin hydroxide chloride is obtained.
Under strongly basic conditions di-t-butyltin oxide is formed which has unusual structural properties and can easily be converted into a ‘dihydroxide'.

Employees who handle dibutyltin dichloride should wash their hands thoroughly with soap or mild detergent & water before eating, smoking, or using toilet facilities.

Contaminated protective clothing should be segregated in such a manner so that there is no direct personal contact by personnel who handle, dispose, or clean the clothing.
Quality assurance to ascertain the completeness of the cleaning procedures should be implemented before the decontaminated protective clothing is returned for reuse by the workers.
All contaminated clothing should not be taken home at end of shift, but should remain at employee's place of work for cleaning.

Wherever possible, safer substitutes should be used in the place of alkyltin compounds.
When Dibutyltin dichloride is necessary to make and use them handling should be done in enclosed systems equipped with exhaust ventilation.

Engineering control should ensure that exposure limits are not exceeded.
Personal protective equipment should be worn, & in appropriate circumstances respiratory protection should be used.
