BioLab fire: Overnight chlorine spike, Atlanta residents warned of haze and odor

ATLANTA - A large white smoke plume remains visible four days after a fire at the BioLab facility in Rockdale County released chlorine and hydrochloric acid into the air. The incident has prompted a nightly shelter-in-place order from 7 p.m. to 7 a.m. over concerns about air quality and health issues among local residents.

According to Rockdale County officials, the fire did not restart on Wednesday, but the increased plume volume and color changes are due to cleanup efforts. "There is product under the building debris that is disturbed during the cleanup process," county officials said. "Until the cleanup is complete, there will be fluctuations in the plume."

The fire, which began Sunday, caused thick smoke to spread across nearby counties. Residents reported difficulty breathing, with some describing the smoke as "thick and heavy." Some noted that it left a noticeable taste and could be felt on the skin. "It almost looked like a whiteout condition," one resident said, describing how visibility dropped to as little as 10 to 15 feet.

Air quality near BioLab facility in Rockdale County

Air quality monitors detected a spike in chlorine levels overnight, and officials are warning that the wind could carry the smoke toward Atlanta, potentially causing haze and a chlorine smell in the city. "Residents may smell chlorine and wake up to hazy conditions Thursday morning," according to a situational awareness alert from the DeKalb County Office of Emergency Management.

In response to the smoke plume's movements, Atlanta Public Schools have moved all outdoor activities indoors for the duration of the school day. Athletic events and after-school activities will be permitted outside. 

Although air quality remains safe for most people, those with pre-existing respiratory conditions have been urged to take precautions. Health officials warn that smoke exposure can cause symptoms such as coughing, shortness of breath, and chest discomfort. People with heart or lung conditions may experience more severe effects.

According to a press release on their website, state and federal agencies are continuing to monitor air quality around the Atlanta metro area. Authorities are using the Trace Atmospheric Gas Analyzer (TAGA), a mobile lab capable of real-time air monitoring, to assess chlorine emissions and other compounds in the air.

Weather forecasts are currently predicting a shift in wind direction for Wednesday night, which could cause smoke and chlorine odors to move westward toward Atlanta. As a result, residents in the metro area may notice haze and the smell of chlorine on Thursday morning. Officials emphasize that while the odor may be noticeable, chlorine can be detected by smell at low, non-harmful concentrations.

Health officials warn that exposure to smoke containing chlorine compounds can lead to symptoms such as eye and airway irritation, coughing, shortness of breath, chest discomfort, headaches, and a runny nose. People with heart or lung conditions may experience more severe symptoms, including chest pain or difficulty breathing. Those at higher risk, such as the elderly, children, and individuals with compromised immune systems, are advised to limit outdoor activities.

To minimize exposure, residents are encouraged to stay indoors, keep windows and doors closed, and run air conditioners on recirculated air if possible. People with asthma or other respiratory conditions should follow their healthcare provider's recommendations.

GEMA says that workers on the site are continuing to make progress neutralizing the product and as the process continues, periodic increases in chlorine levels around the facility can be expected. 

Although current chlorine levels are considered safe, residents are advised to follow guidance from local emergency management agencies. Anyone experiencing symptoms is urged to contact their healthcare provider or the Georgia Poison Center at 404-856-6252 for assistance.

Rockdale County businesses, residents frustrated

The smoke has significantly impacted local businesses. Mitch Henson, a business owner near the affected area, described the conditions as "a whiteout," with visibility reduced to as little as 15 feet due to the thick smoke. He noted that even inside his building, the strong odor of chlorine could still be detected, forcing him to close his business for several days.

This incident is reminiscent of previous chemical accidents in 2004 and 2020, which similarly disrupted the community. 

Roadways and businesses in the path of the smoke remain closed, and sheriff's deputies are blocking off affected areas. Fortunately, schools in the county are currently on break, but government offices have also been shut down for the remainder of the week.

Many residents are frustrated by the ongoing situation, with some wearing masks as a precaution. A lawsuit has been filed by several locals, citing health concerns related to the chemical exposure. The investigation into the incident is ongoing, and further updates are expected.

In response to the ongoing situation, some residents have filed a petition calling for the BioLab facility to be relocated, and attorneys are preparing a class action lawsuit.
