Philadelphia, PA – As households across the Mid Atlantic prepare for winter 2026 27, an invisible and potentially deadly danger deserves attention before heating systems and backup generators see heavy use: carbon monoxide poisoning.
According to NOAA's Weather Prediction Center, carbon monoxide poses a serious safety risk during winter storms and power outages, especially when residents use fuel burning equipment improperly or snow blocks exterior exhaust vents.
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 indoors without warning.
Symptoms include headaches, dizziness, nausea, weakness and confusion. Severe exposure can cause unconsciousness or death, particularly when people are sleeping.
Five Critical Steps to Protect Your Home
1. Check carbon monoxide detectors. Install working CO alarms on every level of your home and outside sleeping areas, following manufacturer instructions and local requirements. Replace expired units.
2. Inspect heating equipment. Have qualified professionals inspect fuel burning furnaces, boilers, fireplaces and associated ventilation systems before winter.
3. Keep generators outdoors. The CDC recommends operating portable generators at least 20 feet from windows, doors and vents, with exhaust directed away from the home. Never run one inside a garage.
4. Clear exterior exhaust vents. Snow and ice can obstruct furnace and appliance vents, potentially allowing dangerous gases to accumulate indoors.
5. Never use cooking appliances for heat. Gas ovens, charcoal grills and camping stoves are unsafe substitutes for residential heating systems.
What to Do if Your CO 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 needs urgent medical evaluation.
Why Mid Atlantic Residents Should Prepare Now
Across Pennsylvania, New Jersey, New York, Delaware and Maryland, winter storms and potential power outages can increase reliance on generators and alternative heating sources.
NOAA also warns that running vehicles inside garages or allowing snow to block tailpipes can create dangerous carbon monoxide exposure.
Checking detectors and heating equipment before temperatures drop is a simple precaution that could save lives.
