Why 72 Hours?

FEMA and the American Red Cross both recommend that every household maintain at least a 72-hour emergency supply kit. The 72-hour standard reflects the typical response time for emergency services to restore basic infrastructure and reach affected areas following a significant disaster — earthquake, hurricane, winter storm, wildfire, or infrastructure failure.

During this window, you may need to:

• Shelter in place without utilities (power, water, gas)
• Evacuate on short notice with only what you can carry
• Support family members with medical needs
• Communicate without cellular infrastructure

Building a 72-hour kit is not difficult or expensive — but it requires deliberate planning done in advance, not in the hours before a disaster strikes.

Water Supply

Water is the single most critical survival resource. Dehydration incapacitates faster than lack of food — especially in hot weather or during physical exertion.

FEMA Recommendation: 1 gallon of water per person per day — minimum. In hot climates or for active individuals, 2 gallons per day is more realistic.

72-Hour Water Checklist

• ☐ 3 gallons of stored water per person (minimum)
• ☐ Water stored in food-grade containers — not milk jugs (they degrade)
• ☐ Water purification tablets or drops as backup
• ☐ Water filtration device (LifeStraw or similar) for extended scenarios
• ☐ Rotate stored water every 6–12 months

Filters up to 1,000 gallons of contaminated water. Removes 99.9999% of bacteria and 99.9% of parasites. No batteries, no chemicals — essential for evacuations near natural water sources.

Holds up to 100 gallons of clean water in your bathtub. Fill it when a storm warning is issued — provides weeks of drinking water for a family of four. Single use, stores flat.

Food and Nutrition

Emergency food should be non-perishable, calorie-dense, require minimal preparation, and be acceptable to everyone in your household including children and anyone with dietary restrictions.

72-Hour Food Checklist

• ☐ Minimum 2,000 calories per person per day
• ☐ No-cook or minimal-cook options (consider fuel source)
• ☐ Manual can opener if storing canned food
• ☐ High-energy snacks: nuts, dried fruit, energy bars, peanut butter
• ☐ Comfort foods — stress is real in emergencies, familiar foods help
• ☐ Infant formula if applicable
• ☐ Check and rotate expiration dates every 6 months

Freeze-dried meals with 30-year shelf life. Just add boiling water. Includes breakfast, lunch, and dinner options. Lightweight and compact for go-bags.

First Aid

A comprehensive first aid kit is non-negotiable. In a disaster, medical facilities may be overwhelmed or inaccessible. You may need to treat injuries, manage chronic conditions, or provide care for days before professional help arrives.

First Aid Checklist

• ☐ Comprehensive first aid kit (100+ pieces minimum)
• ☐ 7-day supply of all prescription medications
• ☐ OTC medications: pain relievers, antidiarrheal, antacids, antihistamine
• ☐ Prescription glasses backup (if applicable)
• ☐ Medical information summary for each family member
• ☐ Blood pressure cuff if anyone has hypertension
• ☐ CPR face shield
• ☐ Israeli bandage or tourniquet for serious bleeding
• ☐ Tweezers for splinter/debris removal
• ☐ Medical scissors and first aid manual

Comprehensive kit with bandages, gauze, antiseptic wipes, wound closures, CPR mask, cold pack, and more. Comes in a hard case. Meets OSHA and ANSI standards for workplace first aid.

Communication and Navigation

Cellular networks and internet infrastructure are often among the first systems to fail during major disasters. Battery-powered and hand-crank communication devices remain operational when digital infrastructure goes down.

Communication Checklist

• ☐ Battery or hand-crank NOAA weather radio
• ☐ Portable phone charger (power bank) — fully charged
• ☐ Solar charger for extended outages
• ☐ Paper maps of your local area and evacuation routes
• ☐ Emergency contact list printed on paper (phones die)
• ☐ Whistle for signaling rescuers
• ☐ Two-way radios (FRS/GMRS) for family communication
• ☐ Local emergency numbers and shelter locations noted

NOAA weather alerts, hand-crank + solar charging, AM/FM/NOAA bands, phone charging port, LED flashlight and emergency beacon. The most comprehensive hand-crank emergency radio available.

Light and Power

• ☐ Headlamp per person (hands-free lighting is essential)
• ☐ Extra batteries in correct sizes for all devices
• ☐ Portable power bank (20,000+ mAh recommended)
• ☐ Solar charging panel for extended outages
• ☐ Candles and waterproof matches (backup only)
• ☐ Glow sticks — safe lighting for children, marks locations

400-lumen output, IPX8 waterproof, red night-vision mode, 200+ hour battery life on low mode. The go-to emergency headlamp for the last decade.

Shelter and Warmth

• ☐ Emergency mylar blankets (one per person — reflect 90% of body heat)
• ☐ Warm sleeping bag rated below expected overnight temperatures
• ☐ Rain poncho per person
• ☐ Work gloves and warm hat
• ☐ Change of clothes per person in waterproof bag
• ☐ Sturdy walking shoes or boots (never evacuate in flip flops)
• ☐ Tent or tarp for outdoor shelter if evacuation required

Documents and Cash

Store copies of critical documents in a waterproof, fireproof container or pouch in your kit. Digital backups in cloud storage are helpful but inaccessible without internet.

• ☐ Photo IDs and passports (copies)
• ☐ Insurance cards and policies
• ☐ Bank account information
• ☐ Property deed or lease agreement
• ☐ Medical records and prescriptions list
• ☐ Cash in small bills — ATMs and card readers may be down
• ☐ Emergency contacts on paper
• ☐ USB drive with digital copies of all documents

Special Needs Items

Customize your kit for every member of your household:

• ☐ Infants: Formula, diapers, baby wipes, bottles, infant medications
• ☐ Elderly or disabled: Mobility aids, hearing aid batteries, extra medications, medical devices
• ☐ Pets: Food, water, leash, carrier, vaccination records, medications
• ☐ Medical equipment users: Battery backup for CPAP, nebulizers, or other powered medical devices

Choosing Your Bag

Your kit container should be:

• Water-resistant or waterproof
• Large enough for 3 days of supplies but light enough to carry
• Easily accessible — not buried in a closet behind other items
• A backpack if your plan includes evacuation on foot

55-liter capacity purpose-built emergency and tactical backpack. MOLLE webbing for attachment of additional pouches, padded back panel, multiple organization compartments. Built to military durability standards.

Maintaining Your Kit

A kit built once and forgotten will fail when you need it. Schedule these maintenance tasks:

• Every 6 months: Check food and water expiration dates, test flashlight and radio batteries, verify medications haven't expired, update documents
• Annually: Replace water if stored in non-sealed containers, review and update clothing sizes (especially for children), assess whether family needs have changed
• After any use: Immediately restock consumed items and replace used batteries
