Using a generator after a Seattle-area power outage? Keep it outside, at least 20 feet away from your home, and point its exhaust away from windows, doors and air vents. That guidance comes from the U.S. Consumer Product Safety Commission (CPSC). Never run a portable fuel-powered generator in a house, garage, basement, carport or any enclosed or partly enclosed space, even if a door is open. Carbon monoxide (CO) from generator exhaust can be fatal.
The safety reminder follows a November 7–8, 2026 National Weather Service wind advisory for the Seattle area and nearby western Washington communities. The alert described south winds around 15–25 mph with gusts reaching 45–50 mph and the possibility of falling tree limbs and some electricity interruptions. This article does not claim a verified count of affected customers or imply that the November 7 advisory remains active. For current conditions, visit NWS Seattle and your electricity provider’s outage dashboard.
How far should a portable generator be from your house?
At least 20 feet, outdoors, according to CPSC’s May 27, 2026 generator safety warning. Keep the exhaust facing away from the building and away from all windows, doors and air intakes. A running generator can produce dangerous carbon monoxide, even when it is just outside an open garage or near a partly enclosed porch. The 20-foot rule is a minimum; follow manufacturer instructions and consider wind direction and nearby buildings.
Where should you never run a generator?
Do not use a portable generator in a home, garage, basement, crawlspace, shed, screened porch, open garage or carport. Opening doors or windows does not make those locations safe. Do not put a running generator immediately below a window, near an HVAC intake, or where exhaust can blow indoors. A small shed or a homemade box can trap exhaust and create a fire or ventilation hazard; use only manufacturer-approved setups that meet the required outdoor clearances.
What are the symptoms of carbon monoxide poisoning?
The Centers for Disease Control and Prevention (CDC) describes carbon monoxide as colorless and odorless. Common poisoning symptoms include headache, dizziness, weakness, upset stomach, vomiting, chest pain and confusion. People who are sleeping may not notice symptoms before becoming seriously ill.
If a carbon monoxide alarm sounds, or you suspect CO exposure, get everyone into fresh air outdoors immediately and call 911. Do not re-enter the building until emergency responders or appropriate professionals declare it safe. Do not wait for every household member to develop symptoms.
Where do I need carbon monoxide alarms?
CPSC recommends working CO alarms with battery power or battery backup on every level of your home and outside sleeping areas. Test alarms as directed and never disable an alarm to stop it sounding during a power outage. Smoke alarms are also important, but a smoke detector is not automatically a carbon monoxide detector unless it is specifically labeled as a combined device.
Can I plug a generator directly into a wall outlet?
No. Never connect a portable generator to your home’s wiring through a regular wall outlet, a so-called double-male extension cord or an improvised cable. This practice, commonly called backfeeding, can endanger utility workers, neighbors and household occupants. If your goal is to energize home circuits, a qualified electrician should design and install code-compliant connection equipment, such as an appropriate transfer switch or approved interlock where permitted by local rules, following the utility’s and the manufacturer’s requirements.
For individual appliances, follow the generator manufacturer’s instructions concerning rated loads, outdoor-use cables, electrical protection and connected devices; do not attempt an improvised wiring solution in wet conditions.
Is it safe to operate a generator during rain or a Seattle windstorm?
Portable generators present shock and electrocution hazards around water. CPSC recommends following the owner’s manual for operation in wet conditions. A generator should remain in an outdoor location with adequate ventilation and safe exhaust clearance; never move it into a garage simply to keep it dry. If you cannot meet both the weather-protection and outdoor-clearance instructions, do not operate it until you can do so safely.
Can I refuel a generator while it is running?
Stop the engine and allow it to cool as the manufacturer directs before adding fuel. Keep fuel containers away from heat, flames and living spaces, and follow locally applicable fire rules. Spilling gasoline onto a hot engine can cause a fire. Store fuel only in approved containers and follow all safety labels.
What should I do first if Seattle-area electricity goes out?
- Check for immediate hazards: Stay well away from downed utility lines and report them to the utility or emergency services as instructed. Treat all downed lines as energized.
- Check your outage provider: Refer to our Seattle power outage map, reporting and restoration guide for official Seattle City Light and Puget Sound Energy resources.
- Protect food: Keep refrigerator and freezer doors shut as much as possible. Use our refrigerator and freezer food safety guide for USDA-based time limits.
- Choose safe lighting: Prefer flashlights or battery-operated lights to candles.
- Use safe backup power: If you have a generator, confirm proper outdoor placement, CO alarms and electrical connections before starting it.
- Check current weather: Consult NWS Seattle for new forecasts, not an archived warning.
Did the November 7–8 Seattle wind advisory mean every neighborhood lost power?
No. The NWS November 7 alert warned that strong gusts could bring down tree branches and cause a few outages. A forecast of possible outages is not an observed customer count. For verified local interruption status, consult the utility’s timestamped outage reporting system. For more guidance on weather alert terms, read our U.S. weather watch, warning and advisory explainer.
