The 72-hour emergency kit is the universally recommended starting point for preparedness — endorsed by the Red Cross, FEMA, and emergency management agencies worldwide. It covers the window before organized emergency response typically reaches affected households.
If you can sustain yourself for three days without external help, you’ve cleared the most critical threshold.
Step 1: Choose Your Container
Evacuation-focused: A 35–65L backpack with padded shoulder straps and hip belt.
Shelter-in-place: A large plastic bin with lid — stores more, doesn’t need to be carried.
Best approach: Both. A grab-and-go backpack + a larger home supply bin.
Keep it in a consistent, accessible location everyone in the household knows.
Step 2: Water
Target: 4 liters (1 gallon) per person × 3 days
| Household | 72h water target |
|---|---|
| 1 person | 12 liters |
| 2 people | 24 liters |
| 4 people | 48 liters |
| 6 people | 72 liters |
- Commercially sealed bottles (rotate every 1–2 years)
- Filled food-grade containers (rotate every 6 months)
- Water filter (LifeStraw or Sawyer) as backup
- Purification tablets as lightweight secondary backup
Step 3: Food
Target: ~2,000 cal/adult/day × 3 days. Prioritize no-cook options.
- Canned goods with pull-tab lids (beans, fish, soup, vegetables)
- Peanut butter
- Crackers or rice cakes
- Granola bars and energy bars (6–9 per person)
- Nuts and dried fruit
- Jerky
- Instant oatmeal (edible with cold water)
- Ready-to-eat pouches
- Candy or chocolate — morale matters
- Electrolyte packs
- Manual can opener
- Spork + paper plates and cups (saves water)
Step 4: First Aid
- Adhesive bandages (assorted)
- Sterile gauze pads and rolls
- Medical tape
- Elastic bandage
- Antiseptic wipes
- Antibiotic ointment
- Blister pads
- Nitrile gloves (2–3 pairs)
- Tweezers + safety pins + scissors
- Pain reliever (ibuprofen or acetaminophen)
- Antihistamine
- Antidiarrheal medication
- Thermometer
- First aid manual (printed)
- Prescription medications — 3–7 day supply, labeled
Step 5: Light
- Headlamp (1 per person) + extra batteries
- Flashlight (backup)
- Battery-powered lantern
- Glow sticks (3–5)
- Candles + matches (backup; never leave unattended)
Step 6: Communication
- Battery or hand-crank radio
- Power bank (10,000+ mAh)
- Charging cables for all devices
- Whistle (3 blasts = universal distress signal)
- Written emergency contact list
Step 7: Documents and Money
- Government-issued ID (copy)
- Passport
- Insurance cards
- Medical information sheet (blood type, allergies, medications)
- Emergency contact list
- Birth certificates (copies)
- Cash: $100–$200 in small bills
Store in a waterproof folder in your kit.
Step 8: Warmth and Shelter
- Emergency mylar blanket (1 per person)
- Warm clothing layer
- Rain poncho (1 per person)
- Extra socks (2 pairs per person)
