5 February 2026 U.S. News

ELIZABETHTON, Tenn. — More than 200 individuals were evaluated and treated at multiple hospitals across Tennessee following a carbon monoxide leak at Milligan University on Wednesday morning. The incident occurred in the Steve Lacy Fieldhouse, where carbon monoxide detectors failed to sound alarms, leading to a delayed response to the hazardous gas infiltration.

Ballad Health, the regional healthcare provider, confirmed that as of early Wednesday evening, it was actively caring for over 200 patients across six of its hospitals. The affected individuals include students, faculty, and staff who were present in the facility when the leak occurred. Emergency crews continue to monitor and respond to the situation, though the total number of exposed persons remains under assessment.

Milligan University officials reported that the leak was identified during routine checks in the morning hours, prompting an immediate evacuation of the Steve Lacy Fieldhouse. Despite the presence of carbon monoxide detectors, they did not activate during the leak, raising concerns about safety protocols and equipment reliability. The university arranged for transportation of those exposed to medical facilities for evaluation and treatment.

Carbon monoxide is a colorless, odorless gas that can cause serious health effects or death if inhaled in high concentrations. According to the Centers for Disease Control and Prevention, symptoms of carbon monoxide poisoning include headache, dizziness, weakness, upset stomach, vomiting, chest pain, and confusion. Immediate medical attention is critical for anyone suspected of exposure.

The Tennessee Department of Health has been notified and is collaborating with local agencies to investigate the incident and ensure public safety. The Occupational Safety and Health Administration provides guidelines for carbon monoxide detection and response, emphasizing the importance of functional alarms and prompt evacuation procedures.

Local emergency responders and hospital staff have been commended for their rapid mobilization and care of those affected. Ballad Health’s coordinated response involved multiple facilities to handle the influx of patients, highlighting the region’s preparedness for mass exposure events.

While the university continues to assess the cause of the detector failure, officials have pledged to review and upgrade safety measures to prevent future occurrences. The incident has sparked renewed attention on carbon monoxide safety in educational institutions nationwide.

For more information on carbon monoxide safety and prevention, the Environmental Protection Agency offers resources and recommendations. Individuals experiencing symptoms consistent with carbon monoxide poisoning are urged to seek immediate medical care and contact emergency services.

As investigations proceed, Milligan University remains closed to affected areas, and students and staff are being kept informed through official channels. The university’s response and the healthcare system’s efforts underscore the critical nature of carbon monoxide awareness and preparedness in community settings.
