Atlanta residents told to shelter inside as chlorine fire smoke covers city in haze - The chemical fire sent chlorine into the air, forcing schools to close and sending tens of thousands of residents

ATLANTA - Air quality monitors near the BioLab facility detected elevated chlorine levels overnight, exceeding safety thresholds, according to Georgia Emergency Management and Homeland Security Agency.

Parts of Atlanta were covered by a haze and the smell of chlorine on Monday, and residents are concerned about the health risk of exposure to chemicals. Here's what some experts say.

According to Georgia Emergency Management Association, Metro Atlanta will wake up to a haze Thursday and possibly the smell of chlorine. And nighttime is when that smoke and air settles towards the ground. It is the reason officials want you to shelter inside in these overnight hours.

Haze and a chlorine odor will likely descend upon Atlanta on Thursday, more fallout from a BioLab chemical fire that ignited in Conyers, Georgia.

Emergency officials have advised residents living near a chemical plant that recently caught fire to remain indoors after 7:00 p.m.
