It started with a malfunctioning sprinkler head. That’s the wild part. On a Sunday morning in late September 2024, a simple mechanical failure at the BioLab facility in Conyers, Georgia, triggered a chemical reaction that would eventually force 17,000 people to evacuate and leave hundreds of thousands more squinting at a hazy, chlorine-smelling sky. It wasn't a "fire" in the way we usually think of one—there weren't massive orange flames licking the clouds at first. Instead, it was a chemical decomposition. Water hit a water-reactive chemical, likely trichloroisocyanuric acid, and the resulting plume of white and gray smoke became a multi-day nightmare for Rockdale County.
Honestly, if you live in Metro Atlanta, you probably remember the smell. It was that sharp, swimming-pool-on-steroids scent that drifted all the way into Fulton and Gwinnett counties. For days, the chemical explosion in Georgia (or more accurately, the chemical reaction and subsequent fire) dominated the news cycle, but the story didn't end when the smoke cleared. It actually got a lot more complicated.
The Chemistry of the Conyers Disaster
The facility was a pool and spa chemical manufacturer. When trichloroisocyanuric acid gets wet, it doesn't just dissolve quietly. It reacts. It generates heat. That heat then causes more of the chemical to decompose, releasing chlorine gas, nitrogen trichloride, and other nasty byproducts.
It’s a runaway train.
The Rockdale County Fire Department found themselves in a nearly impossible position. You can’t just douse a water-reactive chemical fire with more water from a ladder truck. That’s like trying to put out a grease fire with a garden hose. You're basically feeding the beast. They had to balance suppressing the actual fire on the roof with the reality that the chemicals inside were essentially creating their own weather system of toxic vapor.
The plume was massive.
Because of the atmospheric conditions—a phenomenon called a temperature inversion—that smoke didn't just dissipate into the upper atmosphere. It hugged the ground. It crawled across I-20. It sat over neighborhoods like a heavy, stinging blanket. Local officials, including Rockdale County Chairman Oz Nesbitt, had to make the call to shut down the interstate and tell people to stay inside.

This Wasn’t BioLab’s First Time
Here is the thing that really frustrates locals: this wasn't an isolated incident. Not even close. If you look at the records from the Chemical Safety Board (CSB), the Conyers site has a history that reads like a warning manual no one bothered to follow.
- In 2004, a massive fire at the same facility led to the evacuation of 10,000 people.
- In 2020, during the height of Hurricane Laura, a chemical reaction occurred at another BioLab facility in Westlake, Louisiana.
- In September 2020, the Conyers plant again had a "thermal decomposition event."
Basically, the community feels like they’ve been living next to a ticking time bomb for twenty years. When the 2024 chemical explosion in Georgia happened, the "we told you so" from local activists was deafening. The CSB, led by Chairperson Steve Owens, launched an investigation almost immediately, noting the repetitive nature of these accidents. It raises a glaring question about federal oversight and whether "fines" are just seen as the cost of doing business for large chemical corporations.
Health Risks and the Chlorine Haze
What was actually in that smoke? According to the EPA and Georgia EPD monitoring, the primary concerns were chlorine and hydrochloric acid.
If you breathed it in, you knew it.
Chlorine gas reacts with the moisture in your lungs and eyes to form acid. It’s why people were reporting burning throats, watery eyes, and shortness of breath as far as 30 miles away. For most healthy adults, the low-level exposure was an irritant. But for people with asthma, COPD, or cystic fibrosis, it was a legitimate medical emergency.
The advice given by Georgia Poison Center’s Dr. Gaylord Lopez was pretty straightforward: stay inside, turn off your AC, and seal your windows. But that’s easier said than done when your house smells like a bleach factory and you’re worried about your kids. There was a lot of confusion about whether the "safe" levels reported by the EPA actually felt safe to the people coughing on their porches.

The Economic and Legal Fallout
The 2024 event didn't just hurt lungs; it hammered the local economy. I-20 is a major artery for the Southeast. Closing it for hours at a time during the work week ripples through the entire supply chain. Small businesses in Conyers had to lock their doors.
Then came the lawyers.
Within days, class-action lawsuits were filed. Firms like Shiver Hamilton Campbell and others began representing residents who claimed physical injury and property devaluation. The argument is simple: BioLab knew the risks, had a history of failures, and failed to implement the necessary safeguards to prevent a predictable mechanical failure from becoming a regional disaster.
Why We Should Care About Chemical Safety Regulation
This isn't just a Georgia problem. It's a "how we live" problem. We want clean pools. We want cheap chemicals. But the storage of these materials often happens in aging facilities that are grandfathered into old safety codes.
The Environmental Protection Agency (EPA) has been under pressure to tighten the Risk Management Program (RMP) rules. These are the federal regulations that require facilities to predict what happens if things go wrong. After the Conyers incident, there is a renewed push to mandate "inherently safer technology" or "safer alternatives" so that a single broken sprinkler doesn't lead to a multi-county evacuation.
What to Do if You Live Near a Chemical Plant
If the chemical explosion in Georgia taught us anything, it’s that you can’t rely solely on the company’s internal safety measures. You have to be proactive.

1. Know Your Chemicals
Look up the facilities in your "vulnerability zone." You can actually access the EPA’s Risk Management Plan data for your local area. You deserve to know if the warehouse down the street is holding thousands of pounds of anhydrous ammonia or water-reactive acids.
2. The "Shelter in Place" Kit
It sounds paranoid until you see a green-yellow cloud rolling toward your house. You need:
- Plastic sheeting and duct tape (to seal vents/windows).
- A 72-hour supply of bottled water.
- A battery-powered radio (cell towers can get congested).
- N95 masks (though they don't filter gas, they help with particulate matter).
3. Sign Up for Emergency Alerts
Most people in Rockdale County got the "CodeRED" alerts, but many newcomers didn't know the system existed. Go to your county's EMA (Emergency Management Agency) website and register your cell phone right now.
4. Document Everything
If you are currently experiencing health issues related to the Conyers fire, keep a log. Dates, times, symptoms, and doctor visits. Don't wait for a settlement to start organizing your records.
The cleanup in Conyers took weeks. The legal battles will take years. The facility itself—owned by KIK Consumer Products—faces an uncertain future in that community. Public trust is a hard thing to rebuild once it’s been vaporized into a chlorine cloud. As we move forward, the focus has to shift from "how did this happen?" to "why do we keep letting it happen?"
Safety shouldn't be a reaction; it has to be the baseline.
Next Steps for Georgia Residents:
Check the official Georgia EPD website for long-term air quality monitoring reports regarding the Conyers site. If you have lingering respiratory issues, schedule a pulmonary function test with a specialist rather than relying on a general urgent care visit. Lastly, attend the local town hall meetings in Rockdale County; the voices of residents are currently the only thing driving the conversation on whether BioLab will be allowed to resume full operations under the same safety protocols.
