Why 72 Hours Is the Critical Window

Emergency management agencies consistently identify the first 72 hours after a disaster as the period when outside help is least available. Roads may be blocked, emergency services overwhelmed, and utilities down. Your ability to sustain yourself and your family during this window can make an enormous difference in outcomes.

A well-packed 72-hour kit — also called a "go-bag" or BOB (Bug Out Bag) — is the foundation of any solid emergency preparedness plan. Here's what to actually include, and why each item matters.

Water: The Non-Negotiable Priority

Water is your most urgent need. The general guideline is one gallon per person per day, meaning a family of four needs at least 12 gallons for 72 hours.

  • Store water in sealed, food-grade containers away from direct sunlight
  • Include a portable water filter (such as a squeeze-type filter) as a backup
  • Pack water purification tablets for situations where filtration isn't possible
  • Don't forget water for pets — factor their needs separately

Food: Calories Over Comfort

Focus on calorie-dense, non-perishable foods that require little or no cooking. Aim for foods your household will actually eat.

  • Ready-to-eat canned goods (beans, fish, vegetables, fruit)
  • High-calorie nutrition bars or energy bars
  • Peanut butter and crackers
  • Dried fruit, nuts, and trail mix
  • Instant oatmeal or rice (if you can boil water)
  • Manual can opener — easy to forget, impossible to do without

First Aid and Medical Supplies

A comprehensive first aid kit is essential. Pre-made kits are a good starting point, but customize yours based on your household's specific needs.

  • Adhesive bandages in multiple sizes
  • Sterile gauze pads and medical tape
  • Antiseptic wipes and antibiotic ointment
  • Tweezers, scissors, and a thermometer
  • Pain relievers and anti-diarrheal medication
  • Prescription medications: Maintain a 7-day supply and rotate regularly
  • Copies of prescriptions and a basic first aid manual

Documents and Financial Items

Losing access to critical documents during a crisis compounds the difficulty of recovery. Store these in a waterproof pouch or bag:

  • Copies of ID, passport, and driver's license
  • Insurance policies (health, home, auto)
  • Bank account information and emergency contacts list
  • Property deeds, vehicle titles, and will or power of attorney
  • Cash in small bills — ATMs and card readers may be offline

Tools and Safety Items

  • Flashlights with extra batteries (or hand-crank/solar models)
  • Battery-powered or hand-crank radio for emergency broadcasts
  • Multi-tool or Swiss army knife
  • Dust masks or N95 respirators
  • Waterproof matches, lighters, and fire starters
  • Emergency mylar blankets (compact and effective)
  • Whistle to signal for help
  • Duct tape and rope or paracord

Sanitation and Hygiene

Sanitation failures during disasters cause secondary health crises. Pack:

  • Hand sanitizer and antibacterial soap
  • Toilet paper and moist towelettes
  • Heavy-duty garbage bags (sanitation and weatherproofing uses)
  • Personal hygiene items (toothbrush, feminine products, diapers if needed)

Special Needs Considerations

Tailor your kit to your household's specific vulnerabilities:

  • Infants: Formula, diapers, baby food, and comfort items
  • Elderly: Mobility aids, extra medication, medical device batteries
  • Pets: Food, water, leash, carrier, vaccination records
  • People with disabilities: Spare equipment, communication devices, caregiver contact list

Maintaining Your Kit

A kit you built three years ago and never touched is not a reliable kit. Schedule a review every six months — the change of daylight saving time is a useful reminder. Rotate food and water, replace expired medications, and update documents as your situation changes.

Building your kit doesn't have to happen overnight. Start with water and a flashlight today, and add to it steadily. The goal is readiness, not perfection.
