A massive fire at a chemical plant in Georgia prompted the evacuation of 17,000 people, as well as a shelter-in-place order for many others. The shelter-in-place order for Rockdale County was extended indefinitely,

Authorities in Georgia on Sunday issued evacuation orders after a chemical plant caught fire near Atlanta, sending up plumes of black smoke.

Rockdale County officials ordered people to evacuate the area near the BioLab plant in Conyers, Ga., and they said others should stay home to avoid the “harmful irritant chlorine.”
