When disaster strikes — whether it's a natural catastrophe, power grid failure, or civil unrest — the first 72 hours are the most critical. Emergency services may be overwhelmed, roads blocked, and communication down. Your ability to survive those first three days depends entirely on what you've prepared before the crisis hits.
This guide walks you through everything you need to build a solid 72-hour emergency kit, step by step.
Why 72 Hours?
FEMA and most emergency management agencies recommend that every household be self-sufficient for a minimum of 72 hours after a major disaster. In large-scale events, first responders simply cannot reach everyone immediately. Your kit is your bridge to safety.
The Core Categories
1. Water
Water is your top priority. The rule of thumb is 1 gallon per person per day — so for a family of four over 72 hours, that's 12 gallons minimum.
- Store commercially sealed water bottles or food-grade containers
- Include water purification tablets or a portable filter (e.g., LifeStraw)
- Don't forget water for pets
2. Food
Choose non-perishable, calorie-dense foods that require minimal preparation:
- Energy bars and trail mix
- Canned goods (with a manual can opener)
- Freeze-dried meals
- Peanut butter, crackers, dried fruit
- Infant formula or special dietary items if needed
3. First Aid Kit
A basic first aid kit should include:
- Adhesive bandages in multiple sizes
- Sterile gauze and medical tape
- Antiseptic wipes and antibiotic ointment
- Tweezers, scissors, and a thermometer
- Prescription medications (7-day supply minimum)
- First aid manual
4. Light and Power
- Flashlights with extra batteries (or hand-crank/solar)
- Headlamps for hands-free use
- Portable power bank (pre-charged)
- Candles and waterproof matches
5. Communication
- Battery-powered or hand-crank NOAA weather radio
- Whistle for signaling
- Local maps (printed — don't rely on GPS)
- List of emergency contacts written on paper
6. Documents and Cash
- Copies of IDs, passports, insurance policies
- Bank account information
- Small amount of cash in small bills (ATMs may be offline)
- USB drive with digital copies of critical documents
7. Shelter and Warmth
- Emergency mylar blankets (one per person)
- Warm clothing and rain gear
- Sturdy shoes for each family member
- Sleeping bag rated for your climate
8. Tools and Safety
- Multi-tool or Swiss Army knife
- Duct tape and paracord
- Work gloves
- N95 masks and hand sanitizer
- Fire extinguisher

Where to Store Your Kit
Keep your primary kit in an easy-to-grab location near your exit — a hallway closet, garage, or under a bed. Consider a secondary kit in your car. Use a waterproof, durable bag or container.
Review and rotate your supplies every 6 months. Replace expired food, water, and medications.
