The Zachary Co. construction workers were treated at the plant's on-site health facility, spokesman John Coe said. Nine were taken to local hospitals and 11 others sought extra treatment from Zachary medics, Coe said. All were stable Thursday afternoon, he added. There was no residual material detected afterward, Coe said. He said there was no threat to homes or businesses beyond the plant perimeter.
