Wacker’s U.S. polysilicon plant temporarily closed after explosion

Chlorosilane escaped from two leaks after an explosion at Wacker’s polysilicon plant near Charleston, Tennessee (USA) on September 7. Production has been suspended until the cause of the explosion is found.
The escaping chlorosilane was contained with water, which created a huge vapor plume containing traces of hydrochloric acid. Thirteen people with symptoms related to the chemical release were treated at hospitals.
It was the second incident at the plant within eight days; chlorosilane already leaked on August 30. In 2016 Wacker had to pay fines of $3,500 and $4,000, respectively, for violations of safety regulations at the new polysilicon plant.
