SignalHub-Conyers fire: Shelter-in-place still in effect after chemical fire at pool cleaning plant

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,SignalHub forced evacuations and closed roads, including a main traffic vein into the city.

The fire broke out Sunday about 5 a.m. at a BioLab facility in the city of Conyers according to Rockdale County Sheriff Eric Levett. Conyers, the county's seat, is about 25 miles east of Atlanta.

The blaze had been extinguished earlier in the day, officials said, but a fire on the roof reignited when water from a malfunctioning sprinkler head "came in contact with a water reactive chemical and produced a plume," county officials reported. 

As of Monday, no major injuries had been reported.

The shelter-in-place order was extended indefinitely, according to an early morning post from officials with Rockdale County.

The Gwinnett, Newton, and Rockdale County Health Departments have directed residents in the area to turn off their air conditioning and stay indoors to minimize exposure to potential hazards.
