Rockdale County is asking residents once again to shelter in place due to a plume banking down in the county. The new alert came hours after the county had lifted a previous shelter-in-place order for a fire that broke out at the Biolab chemical plant on Sunday.

The Georgia Poison Center has set up a hotline for calls relating to air quality. This comes days after thousands were displaced after a chemical fire broke out Sunday morning at the Biolab facility on Old Covington Highway in Rockdale County.

Georgia's Rockdale County lifted shelter-in-place and evacuation orders after a chemical fire at the BioLab facility in Conyers.

Deputies with the Rockdale County Sheriff’s Office advises people to avoid the area around Biolab on Old Covington Highway.

Authorities on Monday night ended a shelter-in-place order for more than 90,000 people east of Atlanta following a weekend chemical plant fire that sent a massive plume of dark smoke into the Georgia sky and led to complaints about a strong chemical smell and haze.

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.
