CONYERS, Ga. — More than 90,000 residents east of Atlanta were told to keep sheltering in place Monday a day after a chemical plant fire sent a massive plume of dark smoke high into the sky that could been seen for miles.

People in the northern part of Rockdale County were ordered to evacuate and others were told to shelter in place with windows and doors closed.

Manufacturer KIK Consumer Products said it was responding to the incident at its facility, BioLab, in Conyers. No injuries among employees were reported.
