Safety

Tetraphenyltin is potential endocrine disrupting compound. It is a neurotoxin. It is very toxic to aquatic life with long lasting effects. It is toxic if swallowed, in contact with skin or if inhaled. It is dangerous to eyes. It is flammable. The result of combustion is carbon monoxide, carbon dioxide and tin oxides. Vapors of combustion are heavier than air and may spread along floors. Tetraphenyltin vapor forms explosive mixtures with air on intense heating. Its vapor density is 14.7 times greater than air. It is an irritant.
