As artificial intelligence expands, massive data centers are rapidly being built to house high-density servers. To manage high heat loads, some hyperscale facilities use evaporative cooling towers. When inadequately maintained, these systems can harbor Legionella bacteria and cause Legionnaires’ disease. The potential public health risk comes from conditions that allow Legionella to grow and spread within water-based cooling infrastructure—not from AI technology itself.
At Legionnaires Lawyers, we see the serious toll Legionella exposure can take on workers, contractors, and nearby residents. If you or a loved one became ill after exposure to a data center or industrial cooling tower, you may have legal options. Our firm handles Legionella claims, and we can help you understand what compensation may be available.
The Intersection of AI Expansion and Legionnaires’ Disease Risk
Training and running modern AI models requires enormous computing power, which generates significant heat. Some hyperscale data centers use evaporative cooling towers or other water-based heat-rejection systems because these systems can provide efficient cooling for high heat loads.
These systems circulate water and remove heat through evaporation. During operation, small liquid water droplets, or aerosols, can also escape into the surrounding air. That water can support the growth of Legionella bacteria if temperature controls, disinfection levels, or routine maintenance fall short of recommended standards.
Key Exposure Factors
- How mist spreads infection: Cooling towers release aerosolized water droplets as part of their normal function. If that water is contaminated, the bacteria can travel through the air with the mist.
- Who is at risk: Maintenance personnel, HVAC technicians, contractors, other workers who work near cooling towers, and, depending on wind and distance, people in the surrounding community can potentially be exposed to contaminated drift.
Important Note: The rapid construction of AI data centers is a real trend, and cooling towers are a well-documented source of Legionnaires’ outbreaks generally. We are not aware of published outbreak investigations specifically linking the recent AI data center expansion to confirmed Legionnaires’ disease cases. The concern here is based on the known risks of cooling tower systems broadly applied to a fast-growing category of buildings.
Understanding Liability and Negligence in Data Center Cooling Systems
Legionnaires’ disease outbreaks tied to building water systems are, in many documented cases, linked to lapses in maintenance and monitoring.
Facility owners and operators may be subject to state, local, or industry-specific requirements governing Legionella prevention and water-system management. ANSI/ASHRAE Standard 188 is an important industry standard that establishes minimum requirements for managing legionellosis risks in certain building water systems.
ASHRAE 188 does not establish one universal cleaning schedule for every facility. Instead, covered systems are evaluated and a facility-specific Water Management Program establishes monitoring, maintenance, corrective-action, and documentation procedures.
Common Examples of Facility Negligence:
- Failing to conduct the required risk assessment or establish a documented Water Management Program.
- Skipping inspections and cleaning schedules required by the facility’s own risk assessment.
- Failing to maintain adequate disinfectant levels in circulation loops.
- Allowing stagnant water or biofilm buildup inside equipment.
- Ignoring testing rules required by regulations or the facility’s plan, or failing to respond to concerning test results.
When facility operators fail to follow these safety practices, affected individuals may be able to hold them accountable.
Identifying Symptoms and Exposure Risks
According to the CDC, symptoms of Legionnaires’ disease typically appear 2 to 14 days after exposure to contaminated mist, though in rare cases it can take longer.
Because Legionnaires’ disease is a severe, potentially life-threatening form of pneumonia, early medical care is critical.
Common Warning Signs:
- High fever and chills
- Cough (which may bring up mucus)
- Shortness of breath and chest pain
- Muscle aches, headaches, and confusion
HVAC technicians, site contractors, and data center engineers may face elevated occupational exposure risk. Because cooling towers vent mist outdoors, people living or working near a facility can potentially be exposed as well.
Most healthy people exposed to Legionella do not become ill—certain risk factors (such as age, smoking history, or a weakened immune system) increase the likelihood of developing the disease.
Seeking Compensation After Legionella Exposure
A Legionnaires’ diagnosis can bring significant medical bills, lost wages, and lasting respiratory effects. If an improperly managed cooling system contributed to your illness, you may be eligible to pursue compensation.
Building a claim against a facility operator or property manager typically requires detailed technical and medical evidence. Here’s how our team approaches these cases:
- Reviewing Maintenance Records: We request water treatment logs, testing data, and inspection histories.
- Consulting Scientific Experts: We work with industrial hygienists, engineers, and epidemiologists to help trace a probable source of exposure.
- Filing Legal Claims: Depending on the facts of the case, this may include personal injury claims, workplace liability claims, or wrongful death actions.
