Deadly chemical leak in West Virginia

The incident occurred at the Catalyst Refiners facility in Institute during a decontamination process ahead of the plant's planned closure.

Officials believe a lethal buildup of hydrogen sulfide gas was created when workers were cleaning a storage tank.

Over 30 people were treated for exposure, with several arriving at hospitals in private vehicles and garbage trucks due to the chaotic nature of the evacuation.

The local commission is conducting a full investigation into the safety protocols followed during the decommissioning phase.
