What is the most common mistake in building a 72-hour kit?

Not including enough water. People focus on food and gear but underestimate water needs. Store 1 gallon per person per day minimum, plus a portable water filter as backup.

Should I build one big emergency kit or several smaller ones?

Both. Build a comprehensive home kit with 72 hours of supplies, plus a lighter go-bag (30-40 lbs) for evacuation. Also keep basic supplies in your car and workplace.

How often should I update my emergency kit?

Check expiration dates every 6 months (set a calendar reminder). Rotate food and water annually. Update medications quarterly. Replace batteries when you change your smoke detector batteries.

What food should go in a 72-hour emergency kit?

Pack calorie-dense, shelf-stable foods that require no cooking: energy bars, peanut butter, canned goods with pull-tops, freeze-dried meals, and dried fruit. Plan for 2,000 calories per person per day.

72-Hour Emergency Kit Checklist for Beginners

The 72-hour emergency kit is the foundation of all preparedness. FEMA, Red Cross, and every emergency management agency agrees: every household should have supplies to survive 72 hours without outside help. This checklist is designed for beginners — it's practical, affordable, and covers the essentials without overwhelming you.

Why 72 Hours?

72 hours is the standard timeframe for emergency self-sufficiency because that's typically how long it takes for organized disaster relief to reach affected areas. During Hurricane Katrina, many families waited 5+ days for help. Having your own supplies means you're not dependent on a system that may be overwhelmed.

Pro Tip: Build Two Kits

Build one kit for sheltering at home and a smaller "go-bag" version for evacuation. Use this same checklist for both — the go-bag version should prioritize lightweight, compact items.

Water (The #1 Priority)

1 gallon per person per day x 3 days = 3 gallons minimum per person
Water purification: Sawyer Squeeze ($37) or LifeStraw ($19)
Collapsible water container (3-5 gallon) for collecting/carrying water
Water purification tablets as backup (Aquatabs or Potable Aqua)

Food

72-hour emergency food kit: 4Patriots ($27) or ReadyWise 72-Hour ($35)
Energy bars: Clif, Kind, or Millennium bars (high calorie, long shelf life)
Peanut butter or almond butter (shelf-stable calories)
Canned goods with pull-top lids (beans, tuna, chicken, fruit)
Manual can opener (if not using pull-tops)
Utensils: fork, spoon, and bowl or plate

Shelter & Warmth

Emergency Mylar blankets (pack of 4 — cheap and effective)
Emergency bivy sack or sleeping bag (for evacuation)
Tarp (8x10 minimum) + paracord (50 ft) for improvised shelter
Change of weather-appropriate clothing in waterproof bag
Rain poncho or waterproof jacket
Sturdy shoes/boots (by the door, ready to go)

Light & Communication

LED flashlight with extra batteries (or rechargeable)
Headlamp (hands-free light is invaluable)
Hand-crank NOAA radio: RunningSnail ($29) or Midland ER310 ($39)
Battery bank: 20,000mAh minimum for phone charging
Whistle (for signaling — louder than yelling, saves energy)
Glow sticks (for marking paths, safe for children)

First Aid & Hygiene

Comprehensive first aid kit (Adventure Medical Kits recommended)
7-day supply of personal medications in waterproof container
Prescription copies and doctor contact info
Hand sanitizer and soap
Toilet paper + plastic bags (emergency sanitation)
Feminine hygiene products
Sunscreen and insect repellent
Dust mask or N95 respirator (x5 per person)

Documents & Money

Copies of IDs (driver's license, passport) in waterproof bag
Insurance documents (home, auto, health)
Cash: $200-500 in small bills ($1, $5, $10, $20)
Emergency contact list (paper — phones may die)
Local area map (don't rely on GPS)
USB drive with scanned important documents

Tools

Multi-tool or Swiss Army knife
Duct tape (small roll)
Lighter and waterproof matches (2 fire methods minimum)
Permanent marker and notepad
Zip ties (assorted sizes)
Work gloves

Total Estimated Cost

A complete 72-hour kit can be built for $100-250 per person. Many items you already own. Start with what you have, fill in the gaps over 2-3 shopping trips. The most important step is starting — a partial kit is infinitely better than no kit at all.

Frequently Asked Questions

Final Thoughts

Print this checklist, walk through your house, and check off what you already have. You'll be surprised how much you can pull together right now. Then buy the gaps over the next week. Store everything together in a plastic bin or backpack. Test it: can you find everything in the dark? Can you carry the go-bag version for 30 minutes? Preparedness isn't a product — it's a habit.
