Eight people were killed and more than 5,000 evacuated from the vicinity of the leak.
GRANITEVILLE, S.C. (AP) -- A freight train carrying chlorine gas struck a parked train early Thursday, killing eight people and injuring at least 200 others, nearly all of them sickened by a toxic cloud that persisted over this small textile town at nightfall.
Authorities ordered all 5,400 people within a mile of the crash to evacuate in the afternoon because chlorine was continuing to leak and the gas was settling near the ground as temperatures dropped. They were unsure when the gas leak might be sealed.
State Sen. Tommy Moore said Thursday night that officials at Avondale Mill, the textile plant where the crash happened, told him eight people were found dead following the accident, including five inside the mill.
Eight people were in critical condition Thursday night after the 2:30 a.m. wreck of Norfolk Southern trains, in which 16 cars derailed.
Moore said he was told all the deaths were caused by inhaling chlorine fumes, except for the engineer of the moving train, who died in the crash. Sheriff's Lt. Michael Frank said one person was found dead in a home and another was found in a vehicle.
Most of the injured were treated for respiratory ailments and released, but at least 45 people were admitted to hospitals, authorities said.
Residents were jarred awake Thursday by the sound of metal dragging and a house-shaking boom. A chemical fog lay over the crash site when Douglas Brown drove there after hearing the wreck from his home two streets away.
"You could smell it real good. It made your tongue numb, your throat get sore and your eyes get dry," said Brown, who was among those treated.
Authorities convinced all but about a dozen people in the area to evacuate, and set up shelters for evacuees. Gov. Mark Sanford declared a state of emergency for Aiken County.
The potentially fatal gas can damage the respiratory and central nervous systems, and the throat, nose and eyes. Those who were exposed were told to report to decontamination units at two schools.
Three of the 42 cars on the moving train were carrying chlorine, Norfolk Southern spokesman Robin Chapman said.
