Springfield, IL – The Illinois State Fire Marshal is reminding residents that not all carbon monoxide (CO) poisonings happen suddenly. As part of Carbon Monoxide Awareness Month 2025, officials are highlighting the hidden risks of long-term exposure to low levels of the gas.
According to the Fire Marshal’s office, acute CO poisoning can occur quickly — such as when a car is left running in a closed garage or a generator operates too close to a home. However, chronic exposure often develops slowly over days or even months, stemming from small leaks in appliances, vents, or heating systems.
Symptoms like headaches, fatigue, and memory problems may be mistaken for other illnesses, leading to delayed treatment. “Awareness, regular alarm checks, and maintenance of heating systems are key to preventing CO-related illnesses,” officials said.
The National Carbon Monoxide Awareness Association reports that hundreds of Americans die each year from CO exposure, and thousands more seek medical attention for related symptoms.
Residents are urged to install working CO detectors on every floor, test alarms monthly, and schedule professional inspections for fuel-burning appliances.
