What Is a 72-Hour Emergency Kit?

Emergency management professionals widely recommend that every household maintain at least three days' worth of supplies to weather the gap between when a disaster strikes and when organized relief arrives. A 72-hour kit — sometimes called a "go-bag" when packed for mobility — is your household's self-reliance insurance policy.

The goal is straightforward: if you had to leave home in 15 minutes, or were cut off from stores and utilities for three days, this kit keeps you fed, hydrated, safe, and informed.

The Core Categories

1. Water

Water is your top priority. The general guideline is one gallon per person per day, covering drinking and basic sanitation. For a family of four over three days, that's 12 gallons minimum.

  • Store commercially sealed water bottles or food-grade water containers.
  • Include water purification tablets or a portable filter (e.g., a squeeze-style filter) as a backup.
  • Rotate stored water every six to twelve months.

2. Food

Choose foods that require little or no cooking, have a long shelf life, and match your household's dietary needs:

  • Ready-to-eat canned goods (beans, tuna, soup, vegetables)
  • High-calorie, nutrient-dense bars or trail mix
  • Peanut butter and crackers
  • Dried fruit, jerky, and nuts
  • Infant formula or special dietary items if applicable

Don't forget a manual can opener. It's a small item that causes enormous frustration when it's missing.

3. First Aid Supplies

Your kit should include a well-stocked first aid kit with:

  • Adhesive bandages in multiple sizes
  • Sterile gauze pads and medical tape
  • Antiseptic wipes and antibiotic ointment
  • Pain relievers and fever reducers
  • Prescription medications (minimum 7-day supply)
  • Tweezers, scissors, and nitrile gloves

4. Light and Power

  • Flashlights (LED models last longer) with extra batteries
  • Battery-powered or hand-crank lanterns
  • Emergency candles and waterproof matches or lighters
  • A portable battery bank charged and ready for phones

5. Tools and Safety Items

  • Multi-tool or Swiss Army knife
  • Duct tape and paracord
  • Work gloves and dust masks (N95 or KN95)
  • Emergency whistle
  • Tarp or emergency Mylar blankets
  • Cash in small bills — card readers won't work in a power outage

6. Documents and Communication

  • Laminated copies of IDs, insurance cards, and emergency contacts
  • Battery-powered or hand-crank weather radio (NOAA)
  • Local maps (printed — GPS may be unavailable)

Choosing the Right Bag

If your kit needs to be portable, use a sturdy backpack or rolling duffle that every capable adult can carry. Distribute weight appropriately — heavier items low and close to the back. If your kit is primarily for shelter-in-place, a large waterproof bin stored in an accessible location works well.

Maintaining Your Kit

A kit is only useful if it's up-to-date. Set a calendar reminder every six months to:

  1. Replace expired food and medications.
  2. Recharge or replace batteries.
  3. Update documents and prescription lists.
  4. Adjust for changes in household size or needs.

A well-maintained 72-hour kit is one of the highest-value investments you can make in your family's safety. Start building yours today — piece by piece is perfectly fine.
