A shelter-in-place is now in effect for Rockdale County residents following the BioLab chemical fire. Atlanta residents could also soon be impacted.

A small fire on the plant’s roof was initially contained but reignited Sunday afternoon, authorities said. 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.
