Faulty Heater Triggers Mass Carbon Monoxide Poisoning in Nashville Apartments
A faulty temporary gas heater caused a mass carbon monoxide poisoning at a Nashville apartment complex in December 2022. The incident left 69 people affected at the Signature Music Row development. Investigations revealed the heater, installed by property managers LPM Capital Partners, lacked proper ventilation and safety measures.
The poisoning occurred on a Thursday night when unsafe levels of carbon monoxide filled the building. Normal indoor levels range from 0 to 30 parts per million, but anything above 30 becomes hazardous. Standard smoke alarms do not detect the gas, making specialized monitors essential for early warnings.
Victims reported symptoms such as body aches, headaches, and flu-like effects, including vomiting and confusion. Experts later warned that ventless gas logs and fireplaces can also raise poisoning risks, especially in cold weather when heating systems run longer. To prevent similar incidents, homeowners are advised to inspect furnace and water heater vents regularly, particularly after snow or ice storms. Low-level carbon monoxide detectors, which trigger at 15 to 25 parts per million, offer an extra layer of protection. Portable generators, another common hazard, should be placed at least 20 feet from homes and never connected to wall outlets. Overloading them can cause backfeeding into power lines, risking fires or injuries to utility workers.
The Nashville case highlights the dangers of poorly maintained heating systems. Property managers and residents must ensure proper ventilation and use certified safety equipment. Early detection and correct generator use remain critical in preventing future poisonings.
