How to Build a 72-Hour Emergency Kit: A Complete Beginner Guide
Emergencies rarely give advance warning.
Storms, power outages, natural disasters, and unexpected events can disrupt normal life quickly. When this happens, having essential supplies already prepared can make a huge difference.
One of the most recommended preparedness steps is building a 72-hour emergency kit, sometimes called a bug-out bag or emergency supply kit.
This kit contains the supplies needed to support yourself or your family for three days without outside help.

Why a 72-Hour Kit Matters
Emergency responders often recommend being prepared for at least three days after a disaster.
During that time you may experience:
• Power outages
• Limited transportation
• Delayed emergency services
• Closed stores
A properly built emergency kit helps you stay safe while normal services are restored.
Many people also keep emergency gear in their vehicles. If you want to prepare your car as well, see EDC Gear for Your Vehicle: Essential Tools Every Driver Should Carry.
Step 1: Water Supplies
Water is the most important survival supply.
Preparedness experts typically recommend one gallon of water per person per day.
For a 72-hour emergency kit, that means:
• 3 gallons per person
Water can be stored using:
• Bottled water
• Water storage containers
• Emergency water pouches
Recommended Water Storage Options:
LifeStraw Personal Water Filter (backup option)

Emergency food should be:
• Non-perishable
• Easy to prepare
• Long shelf life
Common choices include:
• Energy bars

• Freeze-dried meals
• Ready-to-eat survival rations
Choose foods that require minimal cooking or preparation.

Step 3: Lighting and Power
Power outages are common during emergencies.
Your kit should include reliable lighting such as:
• Flashlight
• Extra batteries
• Emergency radio
Recommended Lighting Gear:
