"We can confirm that an unknown substance (white powder) was found on the floor outside of Gate 6 at Orion Assembly on Monday, August 29. On Tuesday, August 30, we had a second report of a bottle containing a similar substance found inside the plant," GM spokesperson Dayna Hart told The Oakland Press via email.
GM stressed that incident didn't disrupt operations at the plant, and that the company was taking steps to ensure the safety of the sprawling factory's workers. That did include, an anonymous worker told The Oakland Press, closing off parts of the factory for two full days, as drug-sniffing dogs and crews in haz-mat suits descended on the area.
"A sample of the substance has been sent to a laboratory for identification and results are expected later this week," Hart said. "All findings and actions have been shared with our employees."
Orion Assembly currently builds the Chevrolet Sonic and Buick Verano, and will eventually be responsible for production of the new, all-electric Chevy Bolt early next year.
