Why 72 hours?
72 hours is a widely used minimum; Ready.gov currently says several days.
Three days is a starting point
A 72-hour kit is a set of basic supplies for three days. It is not a deadline for help to arrive. After a large emergency, you may need to manage on your own for several days. Start with what you can store, then add more as your space and budget allow.
What goes in a kit?
Ready.gov lists one gallon of water per person per day for several days, for drinking and sanitation. A three-day starting supply is three gallons per person. Plan for pets and any extra household needs too.
- Water and food that keeps without refrigeration
- A flashlight, radio and extra batteries
- First aid and prescription medicines
- A phone charger and backup power
- Copies of important documents and some cash
- Supplies for children, pets and individual needs

Build up step by step
Any preparation counts. Start with 72 hours, then consider 7 or 10 days as space and budget allow. Germany's civil protection agency (BBK) recommends at least 3 days and ideally 10; Ready.gov says several days. For US households, keep using 1 gallon of water per person per day.

Common questions
What is the 72-hour rule?
72 hours is a widely used minimum; Ready.gov currently says several days. Three days is a starting point for planning, not a promise about when help or services will return.
How much water for 72 hours?
Ready.gov lists one gallon per person per day for several days, for drinking and sanitation. For a three-day starting supply, multiply your household size by three gallons, and plan for pets and additional needs.
What should be in a 72-hour kit?
Start with water, shelf-stable food, a flashlight, radio, first aid, phone charging, medicines, documents and cash. Adjust for your household and local risks.
Is 72 hours enough?
Not always. It is a starting minimum, not a ceiling. Hurricanes and other large events can disrupt services for longer. Ready.gov says several days; extend your supplies when possible and follow local officials.
