Power Outage Preparedness Checklist
A solid power outage checklist covers six areas, and you can work through them in a single calm afternoon: water (stored drinking water), food (a few days of no-cook items), light (flashlights, batteries, a charged power bank), warmth or cooling (a plan matched to the season), food safety (knowing how long the fridge and freezer hold), and medical needs (any medication or equipment plans made in advance with your doctor). Add a battery or hand-crank radio to stay informed, and a written list of emergency contacts. None of it is complicated — it's just worth doing before you need it rather than during.
Key Takeaways
- Six areas to cover: water, food, light, warmth/cooling, food safety, medical needs.
- Season changes the plan — summer prioritizes cooling, winter prioritizes safe warmth.
- Keep fridge/freezer doors shut — food stays safe for a limited window.
- Sort medical needs in advance with your doctor, pharmacist, and utility company.
- Generators, grills, and camp stoves: outdoors only — carbon monoxide is deadly.
The Checklist
1. Water
- Store drinking water — a common guideline is around a gallon per person per day for several days.
- Keep a few containers filled and rotate them occasionally.
2. Food
- Stock a few days of food that needs no cooking or refrigeration — canned goods, dried food, nut butters, crackers.
- Keep a manual can opener with the kit (an obvious thing to forget).
3. Light
- Flashlights and spare batteries for every household member, plus a headlamp for hands-free light.
- A charged power bank for phones.
- A battery or hand-crank radio for updates if networks go down.
- Avoid relying on candles — they're a fire risk.
4. Warmth or Cooling (season-dependent)
- Winter: warm layers, blankets, sleeping bags, and one safe indoor heat plan — never outdoor equipment indoors.
- Summer: battery fans, closed blinds against the sun, extra water, and a plan for where to go if heat turns dangerous.
5. Food Safety
- Keep fridge and freezer doors closed as much as possible.
- General guidance: an unopened fridge holds safely for about 4 hours; a full freezer for about 48 hours (24 if half full).
- When in doubt about any perishable food, throw it out.
6. Medical Needs
- Plan ahead with your doctor, pharmacist, and utility company if anyone relies on refrigerated medication or powered medical equipment.
- Keep a written list of medications and emergency contacts.
- Never change medication dosing yourself to stretch supplies.
- For any medical emergency, call your local emergency number (911 in the US) immediately.
A resource worth knowing about
For a calm, plain-language reference to keep on the shelf for times when help or power isn't immediate, The Home Doctor is a practical home-medical guide written by physicians, covering how households can think through common health situations and what supplies are worth having — while always emphasizing when something needs professional care. A reassuring offline companion during an outage; it complements care, never replaces it.

Preparing by Season
In summer, heat is the real risk. Prioritize hydration, battery fans, closed blinds, and knowing where you'd go — a cooling center or a friend's home — if it gets dangerous, especially for children, older adults, or anyone with a health condition. In winter, prioritize warmth: layers, blankets, and one safe indoor heat source, with a hard rule that outdoor equipment (grills, camp stoves, generators) never comes indoors.
What Not to Do
A short list, but an important one: never run a generator, grill, or camp stove indoors or in a garage — they produce carbon monoxide, an invisible, deadly gas. Don't open the fridge or freezer more than necessary. Don't leave candles burning unattended. And don't adjust your own medication to make it last longer — call your pharmacist or doctor instead.
Frequently Asked Questions
What should be on a power outage preparedness checklist?
Water, no-cook food, light and a charged power bank, a warmth-or-cooling plan, food-safety know-how, and a medical plan made in advance. Add a battery radio and a contacts list.
How do you prepare for a power outage in summer?
Prioritize staying cool — battery fans, closed blinds, extra water, and a plan for where to go if heat becomes dangerous.
How do you prepare for a power outage in winter?
Prioritize safe warmth — layers, blankets, and one safe indoor heat source. Never bring outdoor equipment like generators indoors.
What should you not do during a power outage?
Never run a generator, grill, or camp stove indoors — carbon monoxide is deadly. Limit opening the fridge/freezer, don't leave candles unattended, and never change medication dosing on your own.
The Bottom Line
A power outage checklist isn't complicated — it's six ordinary things (water, food, light, warmth or cooling, food safety, and a medical plan) sorted calmly in advance instead of scrambled together in the dark. Match your plan to the season, respect the hard safety rules around generators and heat sources, and put everything somewhere the whole household can find it. Do this once, and the next outage becomes a minor inconvenience instead of a crisis.
