How to Prepare for a Power Outage
🇩🇪 Diesen Artikel auf Deutsch lesenKeep flashlights, batteries, a power bank, water and non-perishable food for several days. Know how to keep food safe: a closed refrigerator stays cold for about 4 hours and a full freezer for about 48 hours. Never run a generator, grill or camp stove indoors or in a garage because of carbon monoxide.
Power outages are becoming more common with severe weather and heat waves. Preparing takes an afternoon and a modest budget.
Step by step
- Build a basic kit
Flashlights or headlamps, extra batteries, a battery or hand-crank radio, a first aid kit and power banks.
- Store water
Keep at least one gallon per person per day for several days, plus water for pets.
- Stock non-perishable food
Canned goods, crackers, nut butter and other foods that need no cooking. Include a manual can opener.
- Plan for medical needs
If anyone depends on powered medical equipment, have a backup power plan and tell your utility; many offer priority programs.
- Protect electronics
Unplug sensitive devices during the outage to avoid damage from surges when power returns.
- Know your home
Learn how to manually open your garage door and where your main breaker and water shutoff are.
- Stay informed
Sign up for your utility's outage alerts and keep phones charged when severe weather is forecast.
Food safety during an outage
| Stays safe (doors closed) | |
|---|---|
| Refrigerator | About 4 hours |
| Full freezer | About 48 hours |
| Half-full freezer | About 24 hours |
Discard perishable foods that have been above 40 °F for more than two hours. When in doubt, throw it out.
Backup power options
- Power banks and portable power stations for phones, lights and routers.
- Portable generators for refrigerators and essentials — outdoors only, with proper transfer equipment for home circuits.
- Home batteries with solar for automatic, silent backup.
Frequently asked questions
Should I report an outage even if neighbors are also out?
Yes. Utilities use reports to locate problems; don't assume someone else has reported it.
Is it safe to use candles?
Battery lights are safer. If you use candles, never leave them unattended and keep them away from anything flammable.
