72-Hour Emergency Kits: What They Are and Why Every Family Needs One
What Is a 72-Hour Emergency Kit?
A 72-hour emergency kit — sometimes called a bug-out bag or go-bag — is a portable collection of supplies designed to sustain one person (or a family) for three full days following a disaster or evacuation. The 72-hour window is based on the general timeframe emergency management agencies estimate before organized relief efforts can reach most affected communities.
Think of it as your personal bridge between a crisis event and the moment when outside help arrives. Whether you're sheltering in place or evacuating to a safer location, your 72-hour kit is your lifeline.
The Six Pillars of a Robust 72-Hour Kit
Formation Industries recommends the 72-hour kit around six core categories to ensure nothing critical is missed:
1. Hydration
• At minimum, one liter of water per person per day
• Portable water filter (e.g., straw-style or pump filter)
• Water purification tablets as a backup
• Collapsible water bottles to reduce pack weight
2. Nutrition
• Compact, calorie-dense foods: energy bars, trail mix, jerky
• Instant oatmeal packets and freeze-dried meals if weight allows
• Small pack of hard candies for morale and quick energy
• Aim for 1,500–2,000 calories per person per day minimum
3. Shelter and Warmth
• Emergency mylar space blankets (lightweight and highly effective)
• Compact rain poncho for each family member
• Change of season-appropriate clothing in a zip-lock bag
• Lightweight tarp or bivy sack for unexpected overnight stays
4. First Aid
• Compact first aid kit with blister treatment, bandages, and antiseptic
• Personal medications (minimum 3-day supply in original packaging)
• Pain relievers and anti-inflammatory medications
• Medical alert card listing blood types, conditions, and allergies
5. Communication and Navigation
• Battery-powered or hand-crank weather radio
• Charged portable power bank and charging cables
• Printed local map and compass
• Whistle for signaling rescuers
6. Documents and Cash
• Photocopies of vital documents in a waterproof sleeve
• Small amount of cash in small bills (ATMs may be down)
• USB drive with digital copies of key files
• Written emergency contact list
Customizing for Your Household
A truly effective 72-hour kit is personalized. A family with infants needs diapers, formula, and baby food. Older family members may require mobility aids or extra medications. Pet owners must pack food and water for their animals. Review your kit every six months — rotate food and water, check battery charge, and update documents.
