Your place · Preparing for emergencies
Getting through a power outage
Keep the fridge and freezer shut: a closed fridge keeps food safe about 4 hours, a full freezer about 48 (24 if half full). Unplug electronics, use flashlights instead of candles, and never run a generator, grill or camp stove indoors or within 20 feet of a window. Stay 35 feet from downed lines. Afterward, throw out perishables that sat above 40°F for 2 hours.
Do it like this
- Check whether it's just you. If neighbors still have lights, check your breaker panel for a tripped breaker. If the whole street is dark, report it to your utility and check its outage map. The Red Cross says that if any breakers tripped during an outage, have an electrician inspect them before you turn them back on. Source: Red Cross
- Keep the fridge and freezer closed. An unopened fridge keeps food cold for about 4 hours. A full freezer holds its temperature for about 48 hours, or 24 if it's half full.

- Unplug electronics and appliances. Power can come back with surges or spikes that damage them. Source: Ready.gov Leave one lamp switched on so you'll know when the power is back.
- Use flashlights, not candles. Candles are a fire risk. Source: Red Cross
- Keep fuel-burning equipment outside. Generators, camp stoves and charcoal grills go outdoors only, at least 20 feet from windows, doors and attached garages. Source: Ready.gov Never use a generator inside your home or garage, even with the doors and windows open. Source: CDC Never heat your home with a gas stove or oven. Source: Ready.gov
- Charge your phone safely. Use a power bank. If you charge in a car, run it outside only. The CDC says never to run a car in a garage attached to a house, even with the door open. Source: CDC
- Sort the food when the power comes back. Never taste food to decide whether it's safe. Throw out refrigerated perishables, like meat, poultry, fish, eggs, soft cheese, milk and leftovers, if they've been above 40°F for more than 2 hours.
