Springfield, Illinois – Illinois officials are urging residents to check carbon monoxide alarms amid freezing temperatures.
According to a Friday Facebook post from the Illinois State Fire Marshal, colder weather increases reliance on furnaces, fireplaces and space heaters — raising the risk of carbon monoxide exposure if equipment is not properly maintained.
The agency reminded homeowners to keep fuel-burning appliances in good working condition, avoid using grills or generators indoors, and ensure vents and chimneys remain clear of snow and debris. Officials also stressed the importance of installing working carbon monoxide alarms on every level of the home and near sleeping areas.
Carbon monoxide is a colorless, odorless gas that can cause sudden illness or death when inhaled at high levels. State officials routinely issue safety reminders during periods of sustained cold, when heating systems operate for extended hours.
The fire marshal’s office emphasized that simple precautions — including testing alarms and replacing batteries when needed — can significantly reduce risk. Officials did not cite any specific incidents in Friday’s post but said prevention remains critical during winter months.
The reminder may be particularly relevant for students, renters and young workers living in apartments or older housing units where heating systems run continuously during freezing weather.
Residents are encouraged to review manufacturer guidelines for heating equipment and to contact local fire departments with safety questions.
