EAST PALESTINE, Ohio (AP) 鈥�
Authorities have started releasing toxic chemicals into the air from five derailed tanker cars that had been in danger of exploding Monday near the Ohio-Pennsylvania state.
Ohio Gov. Mike DeWine ordered evacuations in the area and had warned residents a few hours before the controlled released to leave immediately or face the possibility of death.
The Ohio Emergency Management Agency says the release began Monday around 4:30 p.m., about an hour later than first expected.
Authorities believe most, if not all, residents in the danger zone left before the warning was issued but they were knocking on doors one more time before releasing the vinyl chloride inside the cars that derailed Friday night.
A Norfolk Southern Railway official said doing the release during the daytime will allow the fumes to disperse more quickly and prevent the rail cars from exploding and sending shrapnel flying.
The derailment site in Ohio village of East Palestine is in an industrial area. The evacuation area extends into a sparsely populated area of Pennsylvania.

EAST PALESTINE, Ohio (AP) 鈥� Authorities plan to release toxic chemicals into the air from five derailed tanker cars that were in danger of exploding Monday, telling residents near the Ohio-Pennsylvania state line to leave immediately or face the possibility of death.
Ohio Gov. Mike DeWine ordered evacuations in the area of the derailment that has been smoldering since Friday night. Authorities believe most, if not all, residents in the danger zone have left but they were knocking on doors one more time before releasing the vinyl chloride inside the cars, he said.
鈥淵ou need to leave, you just need to leave. This is a matter of life and death,鈥� DeWine said at press conference ahead of the controlled release planned for around 3:30 p.m. EST.
Scott Deutsch of Norfolk Southern Railway said doing this during the daytime will allow the fumes to disperse more quickly and prevent the rail cars from exploding and sending shrapnel and other debris from flying through the neighborhood.
鈥淲e can't control where that goes,鈥� said Deutsch, who estimated the release would take from one to three hours.
The process involves using a small charge to blow a hole in the cars, allowing the material to go into a trench and burning it off before it's released in the air, he said.
The site is very close to the state line, and the evacuation area extends into a sparsely populated area of Pennsylvania. About half of the 4,800 residents in East Palestine had been warned to leave over the weekend before officials decided on Monday to use the controlled release.
Pennsylvania Gov. Josh Shapiro said the evacuation zone includes about 20 Pennsylvania residences. Pennsylvania State Police were going to door-to-door to assist those residents and ensure that they leave.
鈥淭his is very serious,鈥� he said. 鈥淚 want you to know that if I were there right now, if the First Lady and our children were there right now, we would evacuate. We would leave this area. It is potentially too dangerous.鈥�
Forced evacuations began Sunday night in the village of East Palestine after authorities became alarmed that the rail cars could explode after a 鈥渄rastic temperature change鈥� was observed in a rail car.
Residents were packing overnight bags, loading their pets into cars and searching for hotel rooms Monday morning. Police in the village moved out of their communication center as the threat of an explosion increased.
Police cars, snow plows and military vehicles from the Ohio National Guard blocked streets leading into the area.
About 50 cars, including 10 carrying hazardous materials, night, according to rail operator Norfolk Southern and the National Transportation Safety Board. No injuries to crew, residents or first responders were reported.
Five were transporting vinyl chloride, which is used to make the polyvinyl chloride hard plastic resin in plastic products and is associated with increased risk of liver cancer and other cancers, according to the federal government鈥檚 National Cancer Institute
Federal investigators say the cause of the derailment was a mechanical issue with a rail car axle.
The three-member train crew received an alert about the mechanical defect 鈥渟hortly before the derailment," Michael Graham, a board member of the NTSB, said Sunday. Investigators identified the exact 鈥減oint of derailment,鈥� but the board was still working to determine which rail car experienced the axle issue, he said.
Mayor Trent Conaway, who declared a state of emergency in the village, said one person was arrested for going around barricades right up to the crash. He warned people to stay away and said they'd risk arrest.
鈥淚 don't know why anybody would want to be up there; you're breathing toxic fumes if you're that close,鈥� he said.
