Ohio authorities are letting out nasty, potentially deadly fumes in a flaming train that derailed on Friday to keep it from a possible catastrophic explosion. Ohio Gov. Mike DeWine said the “controlled release” of vinyl chloride, a toxic chemical, would occur on Monday afternoon, warning residents that there remains the “grave danger of death,” according to CNN. DeWine and Pennsylvania Gov. Josh Shapiro have ordered residents near the 1-mile-by-2-mile area surrounding East Palestine to leave. Anyone who remains nearby inhaling the fumes risks death or serious injury via skin burns, serious lung damage, or flying shrapnel which can travel a mile away. “We are ordering you to leave. This is a matter of life and death," DeWine said at a press conference. Anyone who remains may be arrested, according to CNN.
