Winter Power Outage Checklist: Keeping Your Family Warm and Safe
A winter power cut is usually a stay-at-home problem: keep everyone warm without creating a new hazard, protect fridge food, and have light and information when outlets are down. This winter power outage checklist covers supplies, warmth, food safety, kids and babies, and generator rules.

Why Winter Outages Need Their Own Plan
Ready.gov's winter weather guidance notes that winter storms can cut off heat, power and communication, and that older adults, children, sick individuals and pets face greater risk. Most of the time you are not evacuating; you are staying put until the lights come back.
A winter outage plan here is for sheltering at home with light, warmth, water, no-cook food and a few safety rules that do not bend. If circumstances deteriorate and you need to leave, keep a simple go-bag; see the homepage 72-hour go-bag checklist for the full packing list. The full stay-at-home guide and preparation shopping pages below are already in the comprehensive Family Guard binder (downloadable for $39).
Winter Power Outage Checklist: Supplies to Have Ready
Gather these before the forecast turns against you. You need working light, a way to receive news and updates, water, no-cook food, and warmth that does not involve burning fuel indoors — not a warehouse.
- Flashlight or headlamp for each person, plus spare batteries still in the package
- One lantern-style light for a common room (candles only as a last resort — fire risk)
- Battery or hand-crank radio for weather and local news
- Charged power banks and the cables your phones actually use
- Drinking water for several days at home (count pets), plus no-cook food, a manual can opener and trash bags
- Warm layers, hats, gloves, dry socks and extra blankets
- Appliance thermometer for the fridge and freezer
- Carbon monoxide (CO) detectors with battery backup on every level of the home
- Medicine lists, spare critical meds, and a plan for refrigerated medicine or powered devices
- Baby or toddler extras (diapers, formula, wipes, clothes) and pet food, water and a familiar bed
Buy in stages. The Family Guard binder has shopping lists by budget ($50 / $200 / $500) so you can cover water, light and first aid first, then fill gaps over a few paychecks.
Sample Pages From the Family Guard Binder
A preview of two pages from our 38-page binder shows the stay-at-home and shopping format. The complete pages are ready to fill in when you get your copy.
How to Stay Warm During a Power Outage
Warmth without electricity is mostly about holding the heat you already have and dressing for it — not improvising a heater. Ready.gov is clear: never use a gas stove or oven to heat your home. That raises the risk of carbon monoxide poisoning, fires and burns, and can damage the appliance.
- Pick one or two rooms to live in. Close doors to unused rooms; hang blankets over drafty doorways.
- Dress in layers, add a hat and dry socks, and share blankets. A cooler room beats an unsafe heat source.
- Watch for hypothermia and frostbite signs on Ready.gov's winter weather page (shivering, confusion, numb or pale skin) and move somewhere warmer if those appear.
- If the house will not stay safe, leave for a friend's home or a community warming center. Ready.gov suggests checking with local officials about heating locations nearby.
Write a short cold-weather plan while the lights are still on: which room you will use, where the extra blankets live, and when you would leave for heat. That fill-in sits in the Family Guard Binder's home-kit pages next to the power and light checklist above.
Fridge and Freezer Food Safety
Food safety during a power outage is about time and temperature, not smell. FoodSafety.gov's power outage charts, which cite the United States Department of Agriculture (USDA), and Ready.gov's power outage page agree on the basics:
- Keep refrigerator and freezer doors closed.
- An unopened refrigerator keeps food cold for about 4 hours. Discard refrigerated perishables such as meat, poultry, fish, eggs and leftovers after 4 hours without power.
- A full freezer holds temperature for about 48 hours (about 24 hours if half full) with the door closed.
- Throw out food at 40 degrees Fahrenheit (about 4 degrees Celsius) or higher for two hours or more, or that looks or smells unusual. Never taste food to decide. When in doubt, throw it out.
- Hard cheeses, butter, peanut butter and jelly are among FoodSafety.gov's keepers; soft cheeses, milk and opened baby formula are not. Frozen food with ice crystals that still feels cold may be refrozen.
The American Red Cross power outage safety page suggests eating perishables first and using coolers with ice. A cheap appliance thermometer makes the 40-degree line less of a guess. If power is out more than a day, Ready.gov says to discard refrigerated medication unless the label says otherwise, and ask a pharmacist or doctor about a replacement.
Power Outage With a Baby or Young Kids
Ready.gov's winter guidance flags children as a higher-risk group. Keep the plan simple and familiar.
- Stage diapers, wipes, formula or baby food, bottles and clothes where you can reach them by flashlight.
- Dress babies in layers you can add or remove, and follow your pediatrician's usual safe-sleep rules overnight.
- Opened baby formula that needed the fridge follows the same discard rules as other refrigerated perishables on the FoodSafety.gov chart.
- Pack a small calm kit: a favorite toy, board book or card game that works without screens. Tell school-age kids which room you will use and that phones are for texts and saving battery.
- If anyone relies on powered medical equipment, talk to the provider ahead of time, as Ready.gov recommends, and know when you would leave for a place with power.
Pocket cards and a short kids script live in a family emergency binder so a babysitter or grandparent can follow the same plan.
Carbon Monoxide and Generator Safety
Carbon monoxide (CO) has no useful warning smell. Ready.gov's power outage and winter weather pages put it plainly:
- Use generators outdoors only, at least 20 feet away from windows, doors and attached garages.
- Never run a generator, camp stove or charcoal grill inside the home, basement or garage.
- Never heat the house with a gas stovetop, oven, grill or dryer.
- Install working carbon monoxide detectors on every level of the home, with fresh battery backups.
- Keep the generator dry, let it cool before refueling, and use heavy-duty extension cords — do not backfeed into a wall outlet.
The Red Cross repeats the outdoor-and-away-from-windows rule. Flu-like symptoms could be carbon monoxide poisoning. Get into fresh air and seek emergency help.
Put the Checklist Into a Family Plan
Bring pets into the warm room, check on neighbors if you can, and decide ahead when the house is too cold to stay. A winter outage is one scenario inside a wider plan: contacts, medical sheets, stay-versus-go rules and a shopping list. Our article on what to put in a family emergency binder covers those sections. If you must leave, use the free 72-hour go-bag checklist or the full list on the Family Guard homepage.
The Family Guard binder ($39) already includes the home-kit pages for power, light, heating notes and carbon monoxide reminders, plus the $50 / $200 / $500 shopping lists in the same style as the samples above — so you fill in blanks instead of designing worksheets during storm week.
Frequently Asked Questions
How Long Does Food Stay Safe in a Fridge During a Power Outage?
FoodSafety.gov, citing the United States Department of Agriculture (USDA), says an unopened refrigerator keeps food safe for up to about 4 hours with the door closed. Discard refrigerated perishables such as meat, poultry, fish, eggs and leftovers after 4 hours without power. Never taste food to check if it is safe.
How Long Does a Freezer Stay Cold Without Power?
Ready.gov and FoodSafety.gov note that a full freezer holds a safe temperature for about 48 hours with the door closed (about 24 hours if half full). Food may be refrozen if it still has ice crystals or is at 40 degrees Fahrenheit (about 4 degrees Celsius) or below, though quality may suffer.
Is It Safe to Run a Generator Indoors During a Power Outage?
No. Ready.gov says generators and fuel should always be used outdoors and at least 20 feet away from windows, doors and attached garages. Carbon monoxide (CO) is a colorless, odorless gas that can kill you, your family and pets. Install working carbon monoxide detectors on every level of your home.
What Should Be on a Winter Power Outage Checklist?
Include flashlights and spare batteries, a battery or hand-crank radio, charged power banks, warm layers and blankets, no-cook food and water, a fridge and freezer thermometer plan, carbon monoxide detectors with battery backup, and extras for babies, kids, medicines and pets. Ready.gov also suggests plans for refrigerated medicines and power-dependent medical devices.
