Power outage safety tips
- Call the power company. Report the outage and any downed lines, and sign up to receive alerts when the power returns.
- Check the circuit breakers. Be sure they’re turned to the “on” position so power will automatically restore when service returns.
- Never touch downed lines. Keep clear and report them to the utility—downed lines can be deadly.
- Use battery-operated flashlights or lanterns. Candles and oil lamps are fire hazards; rely on battery-operated lights instead.
- Stay warm during winter outages. Bundle in layers, gather family and pets in one room and close the doors. A clean, well-maintained wood stove may provide heat if it is safe to use.
- Stay cool during summer outages. Wear lightweight clothing, spend time in the coolest part of the house and stay hydrated. If the outage is prolonged, consider going to a public cooling location.
- Preserve food. In general, food will stay safe in the refrigerator for up to four hours and in a full freezer for up to 48 hours; avoid opening appliances to maintain cold temperatures.
- Fill water containers if possible. Gather spare jugs and bottles of water to sustain your household during the outage.
- Let faucets drip. During winter outages, letting spigots drip slightly can help prevent frozen pipes.
- Unplug major appliances. Unplug electronics and appliances (except the refrigerator or freezer) to protect them from a voltage surge when power is restored; keep one lamp or device plugged in so you know when power returns.
- Use generators with caution. Only run generators outdoors and follow the manufacturer’s instructions for proper connection and fueling.
- Don’t grill indoors. Charcoal and gas grills produce carbon monoxide and should never be used inside.
- Check on neighbors. Make sure neighbors—especially those who are elderly or disabled—are safe and share supplies if you can.
- Stock an emergency supply. After power is restored, prepare for the next outage by stocking non-perishable food, water, flashlights, batteries, a first-aid kit and any pet or baby supplies you may need.
- Review your homeowners insurance coverage. Your policy may cover food losses, power surge damage, burst pipes and displacement costs; talk to an agent or your insurer for details.
A power outage can occur at any time, so being prepared helps protect your home and family.

Food in a refrigerator is generally safe for up to four hours if unopened; a full freezer can keep food safe for up to 48 hours. Avoid opening appliances to preserve the cold.
Is it safe to run a portable generator during an outage?
Portable generators should only be used outdoors in a well-ventilated area and kept away from windows to avoid carbon monoxide poisoning.
What should I do about essential medical devices that need power?
Have a backup power plan such as battery backups or an alternative location with power, and notify your utility if you rely on electrically powered medical equipment.
Should I unplug my electronics before power is restored?
Unplug sensitive electronics and appliances to protect them from possible surges when power returns; keep one light or device plugged in to know when service is restored.
