EAST PALESTINE, Ohio — Crews began releasing toxic chemicals into the air from five derailed tanker cars that were in danger of exploding Monday after warning residents near the Ohio-Pennsylvania state line to leave immediately or face the possibility of death.
Flames and black smoke billowed high into the sky from the derailment site late in the afternoon, about an hour after authorities said the controlled release would begin. The Ohio Emergency Management Agency confirmed the release was underway.
Ohio Gov. Mike DeWine earlier 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 had left but they were knocking on doors one more time before releasing the vinyl chloride inside the cars, he said.
“You need to leave, you just need to leave. This is a matter of life and death,” DeWine said at press conference.
Officials warned the controlled burn would send phosgene and hydrogen chloride into the air. Phosgene is a highly toxic gas that can cause vomiting and breathing trouble and was used as a weapon in World War I.
Scott Deutsch of Norfolk Southern Railway said doing this during the daytime would 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.
