Faulty piston caused Wacker explosion

Posted

An investigation into what caused the Sept. 7, 2017, explosion at Wacker Polysilicon North America's plant near Charleston has determined the incident resulted from a mechanical failure in the plant’s hydrogen recovery piston.

A new piston, part of an upgraded compressor design purchased last year, fractured resulting in the release of hydrogen that ignited, according to a joint announcement by Wacker and Tennessee Occupational Safety and Health Administration officials.

The investigation used a three-pronged approach with Wacker engineers, an independent team of experts and TOSHA.

“WACKER has discussed both the mechanical compressor failure and the new steps taken to address this type of problem going forward as part of our cooperation with TOSHA during their reviews,” said Mary Beth Hudson, Wacker vice president and Charleston plant manager.

More details will be published in Thursday’s print edition of the Cleveland Daily Banner.
