Start With the 72 Hour Foundation
Most emergencies that disrupt daily life, from a winter storm to a regional power loss, resolve within about three days. That is why FEMA and Ready.gov recommend building a kit that can sustain your household for at least 72 hours without outside help. Think of this as your foundation. Everything else you add later builds on top of it.
The three pillars of the 72 hour foundation are water, food, and the ability to access that food. Water is the single most important item, so plan for one gallon per person per day. That covers drinking and basic hygiene. For a family of four, that means twelve gallons for three days. Store it in clean, sealed, food grade containers, or simply buy commercially bottled water and leave it sealed until you need it.
For food, focus on nonperishable items that need little or no cooking. Canned vegetables, beans, soups, peanut butter, crackers, dried fruit, granola bars, and shelf stable meals all work well. Choose things your family actually likes and will eat. One item people forget every time is a manual can opener. All the canned food in the world does you no good if you cannot open it, so pack one and tape it to the side of a food bin so it never wanders off.
If you want to go deeper on quantities, rotation schedules, and longer term storage, our guide to emergency food and water storage covers it step by step.
- Water: one gallon per person per day, minimum three days
- Nonperishable food: a three day supply per person, no cooking required
- A manual can opener, kept with the food
- Paper plates, cups, and plastic utensils to save water on cleanup
First Aid and Medications
When help may be delayed, you become the first responder for your own household. A well stocked first aid kit lets you handle the small injuries that always seem to happen during stressful times, the cut finger, the burn, the headache, so they stay small.
You can buy a ready made first aid kit and then personalize it, which is often the easiest route. Check the contents once it arrives and add anything your family specifically needs. Keep a simple first aid reference card inside so anyone in the household can use it, not just you.
Medications deserve special attention because a pharmacy may be closed or unreachable. Keep at least a seven day supply of any prescription medication your family depends on, and rotate it so it never expires. Talk to your pharmacist about how to keep an emergency supply on hand, since many will help you plan for this. Do not forget the everyday items either, like pain relievers, allergy medicine, and anything for chronic conditions.
- Adhesive bandages in several sizes, gauze, and medical tape
- Antiseptic wipes, antibiotic ointment, and burn gel
- Tweezers, scissors, and a digital thermometer
- A seven day supply of prescription medications, rotated regularly
- Pain relievers, antacids, allergy medicine, and anything for chronic needs
Light, Power, and Information
When the power goes out, two needs rise to the top: seeing in the dark and knowing what is happening. Both are easy to solve ahead of time, and solving them removes a huge amount of stress from a long, dark evening.
For light, pack flashlights for every member of the family, plus a generous supply of extra batteries in the right sizes. Headlamps are worth considering because they keep your hands free. Avoid candles as your main light source, since open flames are a fire risk during an already chaotic time. If you want a fuller plan for outages, including how to keep food cold and devices charged, read our guide to power outage preparedness.
For information, a radio is essential because your phone may lose signal or run out of charge. Choose a hand crank or battery powered radio, ideally one that can pick up NOAA weather alerts. A hand crank model is reassuring because it never needs fresh batteries, and many include a small charger for a phone. When the cell network is down, that radio becomes your link to official instructions about evacuation, shelter, and safety.
- A flashlight for each person, plus spare batteries
- A headlamp or two for hands free tasks
- A hand crank or battery powered radio with NOAA weather alerts
- A portable power bank for phones, charged and ready
Documents, Cash, and the Things That Are Hard to Replace
In an emergency, paperwork is the last thing you want to think about, which is exactly why you should prepare it in advance. If you ever need to evacuate quickly, having your key documents in one grab and go spot saves you from digging through drawers while the clock is ticking.
Gather copies of the documents that prove who you are and protect what you own, then seal them in a waterproof bag or container. A simple resealable freezer bag works, though a dedicated waterproof pouch is sturdier. Keep originals in a safe place and copies in your kit, so you have a backup either way.
Cash matters more than people expect. When the power is out, card readers and ATMs often stop working, and a small amount of cash in small bills can cover fuel, food, or supplies when nothing else will. Tuck away a modest reserve and resist the urge to borrow from it.
- Copies of IDs, passports, and birth certificates
- Insurance policies, property records, and medical information
- A list of emergency contacts and important phone numbers
- Cash in small bills, kept in the waterproof bag
- A spare set of house and car keys
Hygiene, Comfort, and Sanitation
Staying clean is not a luxury during an emergency. It is how you keep your family healthy when normal services like running water may be limited. A few basic supplies go a long way toward keeping everyone comfortable and preventing illness.
Build a small hygiene kit with the essentials: hand sanitizer, wet wipes, soap, toothbrushes and toothpaste, feminine supplies, and toilet paper. If water service is interrupted, you will also want a plan for sanitation, which can be as simple as heavy duty garbage bags and a supply of moist towelettes.
Comfort items belong here too, especially for a longer event. A change of clothes per person, a sturdy pair of shoes, a blanket or sleeping bag, and a few small comforts like a deck of cards can make a stressful stretch feel far more manageable, especially for children.
- Hand sanitizer, soap, and wet wipes
- Toothbrushes, toothpaste, and personal hygiene items
- Toilet paper, garbage bags, and moist towelettes for sanitation
- A change of clothes and sturdy shoes per person
- Blankets or sleeping bags for warmth
Kids, Pets, and a Kit for the Car
A family kit has to fit your actual family, and that means the youngest members and the four legged ones too. Generic checklists miss these, so take a moment to picture each person and pet in your home and what they would need to get through three days.
For children, pack formula, bottles, diapers, wipes, and any special foods for infants and toddlers. For older kids, a favorite small toy, a comfort item, or a familiar snack can ease anxiety in a big way. For pets, store food, water, a leash or carrier, and copies of vaccination records, since shelters often require them.
Finally, do not keep all your preparedness at home, because emergencies do not wait until you are there. Build a smaller kit for your vehicle. It should carry water, snacks, a flashlight, a blanket, a basic first aid kit, jumper cables, and a phone charger. If you ever get stranded by weather or a road closure, that car kit turns a frightening situation into a manageable wait.

How to Store It and Keep It Ready
A great kit that is buried, scattered, or expired will not help you when it counts. The final step, and the one most people skip, is storing your supplies well and refreshing them on a simple schedule so they are always ready.
Store your kit in one or two sturdy, easy to carry containers, like covered plastic bins or a large duffel, and keep it somewhere cool, dry, and easy to reach. Everyone in the household should know where it lives. If evacuation is a real possibility in your area, keep a smaller go bag near the door so you can leave in minutes.
Set a recurring reminder twice a year to check your kit. A natural trigger is the change to and from daylight saving time, the same weekend you change smoke detector batteries. During each check, replace expired food, water, and medications, test your flashlights and radio, swap out clothes that no longer fit growing kids, and update your documents and contact list. This small habit is what keeps your kit trustworthy year after year.
A kit is only one part of being ready. Pair it with a clear plan for how your family will communicate and where you will meet, which we cover in making a family emergency plan.
- Pack supplies in sturdy, labeled, easy to carry containers
- Store the kit somewhere cool, dry, and known to everyone
- Keep a smaller go bag by the door for fast evacuations
- Check and refresh the kit twice a year, tied to a date you remember
Common questions
How much should it cost to build a family emergency kit?+
It can cost far less than people expect. You likely own much of it already, like flashlights, canned food, and first aid supplies. Start by gathering what you have, then fill the gaps a little at a time. Adding a few items each shopping trip spreads the cost out and gets you to a complete kit without straining your budget.
How much water do I really need to store?+
FEMA and Ready.gov recommend one gallon per person per day, with at least a three day supply. That covers drinking and basic hygiene. For a family of four, plan for twelve gallons to cover 72 hours. If you have space, storing a two week supply gives you an even larger cushion for longer disruptions.
How often should I refresh my emergency kit?+
Check it at least twice a year. A simple trick is to tie it to the change to and from daylight saving time, the same weekend you replace smoke detector batteries. During each check, replace expired food, water, and medications, test your flashlights and radio, and update documents and clothing sizes for growing children.
Do I need a separate kit for my car?+
Yes, a smaller vehicle kit is well worth it because emergencies can strike while you are away from home. Keep water, snacks, a blanket, a flashlight, a basic first aid kit, jumper cables, and a phone charger in your car. If you are ever stranded by weather or a road closure, that kit turns a scary situation into a manageable wait.
Should my kit include important documents?+
Absolutely. Keep copies of IDs, insurance policies, medical information, and emergency contacts in a waterproof bag inside your kit. If you ever evacuate quickly, having these ready saves precious time and protects you while you sort things out afterward. Store originals separately in a safe place as a backup.
