There were concerns a dangerous chemical called styrene could explode after it leaked from a tanker car at a railroad yard, a Central Railroad of Indiana spokesperson told our news partner WCPO in Cincinnati.

Residents were also told to seal off doors and windows, close fireplace dampers, and turn off their heat.

Hamilton County Public Health told WCPO that the air quality had shown, “no issues within the incident zone,” and the nearby water source from the Village of Cleves Waterworks is not experiencing any issues.

As a precaution, health officials asked people to wipe down surfaces and throw unpackaged foods, including pet food.
