A train carrying hazardous materials derailed on a bridge in a southern NJ town near Philadelphia this morning. The Star-Ledger reports, "Three railroad tank cars tumbled into the Mantua Creek and are leaking flammable vinyl chloride after the train bridge collapsed at about 7 a.m."

The Coast Guard has evacuated a half-mile around the derailment in Paulsboro, NJ (map). Schools were locked down as well. Lt. Commander Tracy Wirth said, "What we have done so far is we're standing up an incident management team to help respond to this and manage this response. We are getting more resources in from our Atlantic strike team and public information assist team... The concern, of course, is the product in the air is a flammable gas."

Eleven people were taken to hospitals, while 17 people went to the hospital as walk-ins. According to the EPA, "Acute (short-term) exposure to high levels of vinyl chloride in air has resulted in central nervous system effects (CNS), such as dizziness, drowsiness, and headaches in humans. Chronic (long-term) exposure to vinyl chloride through inhalation and oral exposure in humans has resulted in liver damage."
