Two people ​died following a chemical leak at a ‌silver catalyst plant in Kanawha County, West Virginia, on Wednesday, officials said.

The incident occurred at Catalyst ​Refiners in the unincorporated community of Institute, ​the county commission said in a statement ⁠posted on Facebook, adding one person was ​in critical condition.

More than 30 people, including ​seven emergency responders, were transported or traveled to hospital, some as a precaution, Kanawha County Deputy Attorney Christopher ​Settles said.

“There will be national, state and local ​investigations about this chemical release,” Kanawha County Commission President ‌Ben ⁠Salango said at a news conference.

County officials said they believed a chemical reaction had created deadly hydrogen sulfide gas during cleaning and ​decontamination of ​the plant ⁠in preparation for its closure.

Ames Goldsmith Corporation owned the plant, Salango ​said.

Frank Barber, the president of Ames ​Goldsmith ⁠Corporation, said those who died were employees of the company, ABC News reported, citing a statement.

The ⁠corporation ​did not immediately respond ​to a Reuters’ request for comment.
