UPDATE: Friday, Sept. 8, 2017 at 2 p.m.
Wacker Chemie temporarily shut down operations at the Charleston facility Friday.
It comes after Tennessee Occupational Safety and Health Administration officials arrived at the facility to continue their investigative work.
“Tennessee OHSA started an inspection last week at the Wacker facility related to the employees who were hospitalized after an accident there,” said Steve Hawkins, Assistant Commissioner, TOSHA. “The agency will now expand that inspection to include the event that occurred Thursday afternoon. Two inspectors returned to the facility Friday to determine what led to this latest incident.”
WRCB requested inspection reports from TOSHA over the past two years. From September 2007 to September 2017, TOSHA has investigated 3 incidents, not including Thursday’s “chemical release”.
On Feb. 16, 2016, Wacker was charged a $6,450 penalty with two serious violations. This investigation has been closed, according to WRCB's research.
The next investigation happened a little over two weeks later. On March 2, 2016, Wacker was charged with a $3,500 penalty for one violation considered 'serious'. That investigation has been closed as well.
The third case is still pending from Aug. 30, 2017, and this investigation is still open.

"WACKER's immediate emergency response to contain the release resulted in a visible steam cloud. WACKER is continuously monitoring air quality and measurements confirm air quality is not harmful. All WACKER employees and contractor employees are accounted for. The plant is temporarily closed.

A fire at a chemical plant in Charleston, Tenn. sent a large plume of smoke into the air that can be seen from I-75 and has prompted officials to warn residents to stay inside. The interstate is shut down in that area.
Firefighters were called to Wacker Chemie AG in Bradley County for a reported fire Thursday afternoon.
Bradley County Fire Chief Shawn Fairbanks told Channel 3 his department was working with Wacker to "stop a leak." Bradley County Sheriff's Office spokesman James Bradford said the smoke was caused by a low concentration of hydrochloric acid.
Eyewitnesses said they heard a loud sound and then saw heavy smoke coming from I-75 north. We've heard from viewers in McMinn and Monroe counties who said they heard the boom.
