Every emergency management agency says the same thing: have 72 hours of supplies ready. FEMA says it. The Red Cross says it. State emergency management offices say it.

Most people nod and move on.

The ones who don't — the ones who build the kit — nearly all run into the same problem: they put together what they think is 72 hours of supplies and find out during an actual emergency that it was closer to 18. The water runs out on day one. The medications aren't labeled. The flashlight batteries are dead. The kids' snacks were eaten weeks ago.

The gap between "I have a kit" and "I have a kit that actually works" is about thirty minutes and one good checklist.

What "72 Hours" Actually Means

Three days. For every person in your household, including pets.

That means:

  • Water: One gallon per person per day, minimum. For a family of four, that's 12 gallons. For three days in summer heat with physical exertion, it's more.
  • Food: 2,000–2,500 calories per adult per day. Calorie-dense, no-cook options. Don't forget utensils.
  • Everything else: Medications, documents, first aid, sanitation, communication, light, warmth.

The "everything else" is where most kits fall apart — not because people don't care, but because they've never seen a real list.

Where Most Kits Fall Short

Medications are the most common failure point. People know to include them but don't maintain them. A 7-day supply of prescription medication expires, runs out, or sits in the kit while the daily supply is used elsewhere. The fix is a monthly kit check: first day of each month, rotate your medications.

Documents that exist only in digital form. If your phone dies and the internet is down, your insurance card in an app is useless. Print the essentials and store copies in a waterproof bag.

The family contact plan. If your household separates during an emergency — kids at school, spouses at different workplaces — you need a pre-agreed meeting point and a single out-of-state contact everyone checks in with. This costs nothing and solves an enormous amount of chaos.

Pet logistics. Emergency shelters often do not accept pets. If you're evacuating, you need pet food, veterinary records, carriers, and a plan for where the animals go. Don't wait until you're in a parking lot at 2 AM figuring this out.

Putting It Together Without Overwhelming Yourself

You don't have to build the kit in one afternoon. The checklist above is the full version — comprehensive and a little intimidating if you approach it all at once.

A more realistic approach: three phases over three weeks.

Week 1 — Water and food. Get your water supply in place (a case of water bottles is enough to start, gallon jugs are better). Stock a few days of shelf-stable food you already eat.

Week 2 — Documents and medications. Print your emergency documents. Build your medication backup supply. This is the phase most people skip — don't.

Week 3 — Everything else. First aid, tools, communication. Most of this you may already own. Gather it into one place so you know where it is.

The Printable Version

If you're putting a physical kit together, having the checklist on paper in the kit saves you from having to remember what you included — and lets anyone in your household verify the kit without your help.

Our Hurricane Preparedness Kit includes a printable 5-bundle PDF set: a full emergency supply checklist, family safety plan, go-bag packing list, contact cards, and pet emergency info. Designed to live in the kit and be used during the emergency, not just before it.

After You Build It: Maintenance

A kit that isn't maintained is a false sense of security.

Every 6 months: Check and rotate water supply. Check food expiration dates. Test flashlight and radio batteries. Verify all family members know where the kit is.

Every year: Update documents (insurance, IDs, vehicle info). Rotate medications. Check that clothing still fits (especially children's items). Review evacuation routes — they may have changed.

Set a recurring calendar reminder. It takes 20 minutes twice a year.

The goal of a 72-hour kit is not to be a prepper or plan for every possible disaster. It's to give yourself three days to figure out what comes next without chaos. Three days is enough time for power to be restored, for shelters to open, for family to reach you, for you to reach them.

The checklist is just the vehicle. What it's really for is the first night — when everything goes wrong and you reach for the bag and everything you need is there.
