Chicago, IL – As households across the Great Lakes region prepare for winter 2026 27, an invisible and potentially deadly danger deserves attention before freezing temperatures, lake effect snow and winter storms arrive: carbon monoxide poisoning.
According to NOAA's Weather Prediction Center, carbon monoxide is a serious winter safety concern, particularly when residents rely on portable generators, fuel burning heating equipment or other appliances that can produce dangerous exhaust.
Why Carbon Monoxide Is Called the Silent Killer
Carbon monoxide CO is a colorless, odorless gas produced when fuels such as natural gas, propane, gasoline, oil, wood and charcoal burn incompletely.
Because the gas cannot be detected by sight or smell, dangerous concentrations can accumulate inside homes without warning.
Early symptoms include headaches, dizziness, nausea, weakness and confusion. Severe poisoning can cause unconsciousness or death, particularly when people are sleeping.
Five Critical Steps Before Winter 2026 27
1. Install and test carbon monoxide detectors. Place working CO alarms on every level of the home and outside sleeping areas, following manufacturer instructions and local requirements. Replace expired units and check batteries where applicable.
2. Inspect heating equipment. Have a qualified professional inspect fuel burning furnaces, boilers, fireplaces and associated ventilation systems before heavy winter use.
3. Keep portable generators outdoors. The CDC recommends operating generators at least 20 feet from doors, windows and vents, with exhaust directed away from the home. Never operate one inside a garage, even with the door open.
4. Keep exterior exhaust vents clear. Heavy snow, drifting snow and ice can obstruct furnace and appliance exhaust outlets, potentially allowing dangerous gases to accumulate indoors. Check accessible vents after significant snowfall.
5. Never use cooking appliances for heat. Gas ovens, charcoal grills and camping stoves are unsafe substitutes for residential heating equipment.
What to Do if Your Carbon Monoxide Alarm Sounds
Immediately evacuate everyone outdoors into fresh air and call 911.
Do not attempt to locate the source or reenter the building until emergency responders determine it is safe.
Anyone experiencing symptoms should receive urgent medical attention.
Why Great Lakes Residents Should Prepare Now
Across Illinois, Indiana, Michigan, Wisconsin, Ohio and nearby communities, winter storms can bring prolonged freezing temperatures, lake effect snowfall and power outages.
Heavy snow can obstruct exhaust vents, while extended outages may increase reliance on generators and alternative heating sources.
Residents should also clear snow from vehicle tailpipes before starting engines and never leave vehicles running inside attached garages.
Preparing before the first major winter storm is one of the most effective ways to reduce these preventable risks.
