Home protection · Emergency kits

Build a kit you can live out of for three days — and a bag you can grab in three minutes

An emergency kit is two things. One is a stash at home that carries your household through several days without power, water pressure, or a trip to the store. The other is a bag you can pick up on the way out the door. This guide covers what goes in each, how much water and food to plan for, and how to keep it all from quietly expiring in the closet.

01Stay-put supplies versus the go-bag

Most emergencies mean staying home without utilities. Some mean leaving fast. These need different kits — one big and heavy, one small and portable — and trying to make one box do both usually means it does neither well.

Stay-at-home kit

  • Stored in one closet or set of bins
  • Water for several days to two weeks
  • Shelf-stable food and a way to heat it
  • Lights and battery power
  • Sanitation and cleaning supplies
  • Full first aid and medications

Go-bag

  • One backpack per person
  • Water and snacks for a day or two
  • Change of clothes and sturdy shoes
  • Copies of IDs, insurance, and contacts
  • Phone charger and power bank
  • A few days of medications

02Water and food — the foundation

Water is the first thing to run out and the hardest to improvise. Plan on about one gallon per person per day for drinking and basic hygiene, and more for hot weather, nursing mothers, sick family members, and pets.

Household3 days of water2 weeks of water
1 person3 gallons14 gallons
2 people6 gallons28 gallons
4 people12 gallons56 gallons
4 people + a dogAbout 13–14 gallonsAbout 60–65 gallons
Based on the one-gallon-per-person-per-day baseline. Pet needs vary with size; add extra in heat.
  1. Store some, plan to make more

    Sealed commercial water is the easiest to store. A barrel adds bulk capacity, and a tub liner lets you fill a bathtub with clean water right before a storm.

  2. Add a filter as backup

    A personal filter can make questionable water safer to drink if stored water runs out. Boiling, when you can, remains the standard for killing germs.

  3. Choose food you'll actually eat

    Canned goods, peanut butter, crackers, and dried fruit work. Freeze-dried meals last a very long time and just need hot water.

  4. Don't forget a can opener and a heat source

    A manual can opener and a small camp stove — used outdoors or with good ventilation — make your food supply far more usable.

03The rest of the stay-at-home kit

Beyond water and food, a home kit covers light, information, first aid, sanitation, and staying warm or cool. Group items by job so you can find them in the dark.

Light and power

LED flashlights or headlamps for each person, spare batteries, a lantern, and power banks for phones.

Information

A battery or hand-crank radio with NOAA weather alerts, plus a printed list of phone numbers.

First aid

A well-stocked kit, a week or more of prescriptions where possible, and any glasses, hearing-aid batteries, or medical supplies.

Sanitation

Garbage bags, wet wipes, hand sanitizer, toilet paper, and a bucket with a lid if plumbing is out.

Tools

A multi-tool, duct tape, work gloves, and a wrench or pliers to shut off utilities if you need to.

Air protection

N95 respirators for wildfire smoke, dust from cleanup, or mold after a flood.

04Pack the go-bag and protect your paperwork

If you have to leave, the hardest things to replace are documents, medications, and information. A go-bag is mostly about those — not survival gear.

  • Copies of IDs, passports, and insurance policies in a waterproof bag
  • A USB drive or secure cloud folder with scans of the same documents
  • Photos or video of every room for insurance claims
  • Several days of prescriptions plus a written list of doses
  • Spare glasses, chargers, and a full power bank
  • Some cash in small bills
  • Comfort items and snacks for kids
  • Pet food, leash, carrier, and vaccination records

05Keep the kit current with a twice-a-year routine

Kits fail quietly — batteries leak, water gets used for a camping trip, medications expire, kids outgrow the clothes. Pair a kit check with a date you already remember.

  1. Spring
    Full inventory.

    Check expiration dates on food, water, medications, and first aid supplies. Swap out anything within a few months of expiring.

  2. Before your season
    Fill the gaps.

    Ahead of hurricane, wildfire, or winter season, restock what you used and add anything specific to that hazard.

  3. Fall
    Second check.

    Test flashlights and the radio, recharge power banks, and update clothing sizes and the contact list.

  4. After any use
    Restock right away.

    The week after an outage is when you'll remember what ran out. Make the shopping list then, not next spring.
