Seattle, WA – As households across the Pacific Northwest prepare for winter 2026 27, an invisible and potentially deadly danger deserves attention before winter storms, mountain snowfall and power outages arrive: carbon monoxide poisoning.
According to winter safety guidance from NOAA's Weather Prediction Center, carbon monoxide is a serious concern during cold weather emergencies, particularly when residents use portable generators, fuel burning heaters or other equipment 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 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 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 state requirements. Replace expired units and check batteries where applicable.
2. Inspect heating equipment. Have a qualified professional inspect fuel burning furnaces, fireplaces, wood stoves and ventilation systems before winter. Damaged or poorly maintained equipment can release dangerous exhaust.
3. Keep generators outdoors. The CDC recommends operating portable 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 mountain snowfall, drifting snow, ice and debris can obstruct furnace and appliance exhaust outlets. Check accessible vents after storms without climbing onto dangerous surfaces.
5. Never use cooking appliances for heat. Gas ovens, charcoal grills and camping stoves are unsafe substitutes for residential heating equipment and can create life threatening carbon monoxide exposure.
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 Pacific Northwest Residents Should Prepare Now
Across Washington, Oregon and Idaho, winter storms can bring damaging winds, freezing rain, heavy mountain snow and widespread power outages.
In western Washington and Oregon, strong windstorms can knock down trees and power lines, increasing reliance on portable generators.
Farther inland and in higher elevations, snow accumulation can block exhaust vents while extended cold weather increases heating demand.
Residents should also clear snow from vehicle tailpipes before starting engines and never leave vehicles running inside attached garages.
Preparing before the first significant winter storm is one of the most effective ways to reduce these preventable risks.
