How to Build a 72-Hour Emergency Kit: Checklist by Household

Build a 72-hour emergency kit from the Ready.gov basic list: water, food, radio, light, first aid, documents and medications, scaled for kids, seniors and pets.

Quick answer

A 72-hour kit covers each person for three days without help: 1 gallon of water per person per day, three days of non-perishable food, a battery or hand-crank NOAA weather radio, flashlights and spare batteries, a first aid kit, a whistle, dust masks, a manual can opener, phone chargers and a backup battery, medications, copies of documents and some cash. Add supplies for infants, older adults and pets.

A 72-hour kit is not about doomsday. It is for the first three days of an outage, storm or evacuation, when help and stores may not be available.

The basic kit

Item Amount or note
Water 1 gallon per person per day, at least 3 days
Food 3 days of non-perishable food that needs no cooking
Weather radio Battery or hand-crank, NOAA Weather Radio band
Flashlights One per person, plus spare batteries
First aid kit Restocked and checked
Whistle To signal for help
Dust masks N95 or similar
Plastic sheeting and duct tape Shelter in place
Moist towelettes, garbage bags, ties Sanitation
Wrench or pliers To turn off utilities
Manual can opener For canned food
Local maps If phones are down
Phone chargers and backup battery Charged

This list follows Ready.gov’s basic disaster supplies kit.

Add for your household

Who Add

Infants Formula, bottles, diapers, wipes
Older adults Mobility aids, hearing aid batteries, medical device power

Packing

Use a backpack or rolling bin you can carry. Keep a home kit, a smaller go-bag and a car kit. Store water separately if the kit gets too heavy; see emergency water storage.

Keep it current

Set a yearly reminder to rotate food and water, refresh medications and test the radio. Choose a weather radio with alerts for your county.

Common questions

What should be in a 72-hour emergency kit?

Water, food, a weather radio, flashlights, batteries, first aid, a whistle, masks, a can opener, chargers, medications, documents and cash, per Ready.gov's basic kit list.

How much water for a 72-hour kit?

At least 3 gallons per person: 1 gallon per person per day for drinking and sanitation.

Should I buy a pre-made kit or build one?

Pre-made kits are a fast start but often skimp on water, light and first aid. Build your own or upgrade a kit's weak items.

How often should I check my emergency kit?

At least once a year. Replace expired food, water, medications and batteries, and update for growing kids.
