On Feb. 3, a train of about 150 freight cars many carrying several loads of hazardous materials " crashed and exploded in the town of East Palestine, Ohio. The tangled knot of boxcars operated by Norfolk Southern Railway shot out flames reaching 100 feet and sent a massive plume of coal-black smog. Five days later, crews ignited a controlled burn of the toxic chemicals in order to prevent a much bigger explosion, but the situation appears to be worsening. Residents and local news agencies have posted viral videos of streams and creeks cluttered with dead fish and frogs. Reports have also surfaced that fumes sickened and even killed pets. Many are drawing comparisons to the 1986 Chernobyl nuclear disaster, which turned Pripyat, a city of roughly 50,000 people, into a ghost town. "We basically nuked a town with chemicals so we could get a railroad open," Sil Caggiano, a hazardous materials specialist, told WKBN. On Feb. 8, state officials told residents that they could "safely" return home. "If it's safe and habitable, then why does it hurt?" Nathen Velez, a resident of East Palestine, said to CNN. "Why does it hurt me to breathe?" As more details emerge, the gravity of the situation only seems to worsen. In a letter sent to Norfolk Southern Railway on Feb. 11, the Environmental Protection Agency (EPA) said that in addition to vinyl chloride, four additional toxic chemicals were on board the train: ethylene glycol monobutyl ether, ethylhexyl acrylate, butyl acrylate and isobutylene.
