A shelter-in-place order remained in effect Monday in parts of greater Atlanta after a chemical fire at a pool cleaning facility shot plumes of black smoke into the air, forced evacuations and closed roads, including a main traffic vein into the city.

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.
