Other counties reporting smell & haze: The City of Atlanta says fire personnel and Hartsfield-Jackson airport personnel are conducting air quality testing. Many in Gwinnett County have reported a haze and smell, and Gwinnett County Public Schools has canceled outdoor activities for Monday, Sept. 30, and cut outside air from coming into buildings.

BioLab is a company that makes pool and spa treatments, and the chemicals involved in that process appeared to exacerbate the fire and send up huge smoke clouds. The fire later reignited around noon, according to authorities, and was put out around 3:30-4 p.m. on Sunday.
