Residents of East Palestine, Ohio, were told to urgently evacuate their town Sunday night, two days after a train derailed in the area of about 4,700 residents.

The derailment occurred late Friday and did not cause any injuries. Although two days had passed, Ohio Gov. Mike DeWine said late Sunday that officials measured a "drastic temperature change" in a rail car. He warned of a "catastrophic explosion" that could send shrapnel a mile away from the crash.

Air near Ohio train derailment deemed safe for residents to return

Officials said East Palestine residents can return home after being evacuated due to burning toxic gases from portions of the 50-car derailment.

"We've had a drastic change in the chemical inside the tank cars that we've been concerned about and watching all day, the vinyl chloride. We are at a risk now of a catastrophic failure of that container," East Palestine Fire Department Chief Keith Drabick said at a news conference. "Measures are being taken to try and control that and prevent that from happening." 

He said most people within one mile had already evacuated, but he estimated that about 500 residents remained at the time of his warning. 

He said shelters were open for residents needing somewhere to go.

"Although teams are working to prevent an explosion from happening, residents living within a mile of the site are advised to immediately leave the area," DeWine's office said in a statement.

Officials are still trying to determine what caused the derailment.

According to the Environmental Protection Agency, vinyl chloride is highly flammable and is mostly used to make polyvinyl chloride (PVC) plastic and vinyl products. Short-term exposure to the chemical can cause dizziness, drowsiness and headaches. Long-term exposure can result in liver damage and cancer concerns, the EPA said.
