Why 72 Hours?
Emergency management agencies worldwide recommend that every household be prepared to be self-sufficient for at least 72 hours (three days) following a major emergency. This is the typical window before organized relief services can reach most affected areas. Whether the emergency is a severe storm, an earthquake, a power grid failure, or a public health crisis, the first three days are often the most chaotic — and the most dangerous for those who are unprepared.
The Core Categories of a 72-Hour Kit
A well-stocked emergency kit covers six fundamental categories:
1. Water
Water is your most critical resource. The standard recommendation is one gallon (approximately 4 liters) per person per day — more in hot climates or for people with medical needs. For a family of four over 72 hours, that's a minimum of 12 gallons. Store water in sealed, food-grade containers and rotate your supply every six months.
Also include a portable water filter or purification tablets in case your stored supply runs out or becomes contaminated.
2. Food
Focus on non-perishable, high-calorie foods that require minimal preparation:
- Canned goods (beans, tuna, vegetables, fruit)
- Peanut butter and crackers
- Dried fruit, nuts, and granola bars
- Ready-to-eat meals (MREs)
- Baby food or formula if applicable
Include a manual can opener. Check expiration dates every six months and rotate stock.
3. First Aid
Your kit should include a comprehensive first aid kit containing:
- Bandages, gauze, and adhesive tape
- Antiseptic wipes and antibiotic ointment
- Pain relievers and anti-diarrheal medication
- Prescription medications (keep a 3–5 day supply rotated regularly)
- First aid manual
- Gloves and a CPR face shield
4. Light, Communication, and Power
- Flashlights with extra batteries (or hand-crank models)
- Battery-powered or hand-crank weather radio
- Fully charged portable power bank for phones
- Whistle to signal for help
- Candles and waterproof matches (use with caution indoors)
5. Documents and Cash
Store waterproof copies (or originals in a sealed bag) of:
- Identification documents (passports, IDs)
- Insurance policies and medical records
- Emergency contact list
- Small amount of cash in small denominations (ATMs may be down)
6. Warmth, Shelter, and Hygiene
- Emergency mylar blankets (one per person)
- Warm clothing and sturdy shoes stored with the kit
- Basic hygiene supplies: hand sanitizer, soap, toilet paper, feminine products
- Dust masks or N95 respirators
Where to Store Your Kit
Keep your primary kit in an easily accessible, central location — many families use a large backpack or rolling bag stored near the main exit. If you have a vehicle, maintain a smaller secondary kit in the car. If you have a workplace kit policy, consider keeping a small kit at your desk as well.
Special Considerations
| Household Member | Additional Items |
|---|---|
| Infants | Formula, diapers, wipes, baby medications |
| Elderly individuals | Extra prescription meds, mobility aids, medical devices |
| Pets | Pet food, water, leash, carrier, vaccination records |
| Individuals with disabilities | Specialized equipment, extra batteries for devices |
Review and Refresh Annually
An emergency kit is only valuable if it's functional. Set a calendar reminder twice a year — many people use daylight saving time changes as a reminder — to check expiration dates, replace batteries, update documents, and ensure the kit still meets your family's current needs.
Building your kit doesn't have to happen all at once. Start with water and food this week, add first aid supplies next week, and build from there. A partially stocked kit is far better than none at all.
