Leaking rail tanker prompts HazMat response in Kansas City

KANSAS CITY, Mo. - A rail tanker leaking flammable material in Kansas City prompted a response from HazMat crews Sunday night.

The leaking tanker was first noticed about 7 p.m. by Kansas City Southern Railway workers near North Chouteau Trafficway and Gardner Avenue, in the Union Pacific rail yard. Authorities initially said the tanker was leaking Chlorobutane, a highly-flammable, colorless liquid. Chlorobutane vapors can travel to a source of ignition and flash back. However, fire officials later said it appeared that the leak was made up of a mixture of waste chemicals.

It was not immediately clear what caused the leak.

Fire crews were waiting for a chemist from a local company to arrive and help supervise the offloading of the material into another vessel. Battalion Chief James Garrett said there was no way to stop the leak. Rather, the leaking material was being contained until it could be transferred to the other vessel.
