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.

For everyone sheltering in place, the best practice is to turn the air conditioning off and keep windows and doors shut,” a statement said.

Authorities in the Atlanta area are now reporting a "strong chemical smell" in the air following a chemical plant fire on Sunday in Conyers, Georgia.
