72-Hour Emergency Plan: What to Do in the First 3 Days of a Crisis

The first 72 hours after a disaster are the most critical. Power goes out, shelves go empty, emergency services are overwhelmed, and panic spreads. That’s why every prepper needs a solid 72-hour emergency plan.

This isn’t just about gear—it’s about decisions. What you do (or fail to do) in the first three days determines your long-term survival. Here’s how to prepare, act, and outlast when things go sideways fast.

Why 72 Hours?

FEMA, Red Cross, and survival experts all agree: 72 hours is the minimum window it takes for help to arrive—or for things to stabilize.

⏳ Power outages can last for days
⛽ Gas stations may close or run dry
🛒 Supermarkets are cleared out within hours
🚓 Law enforcement shifts focus to major chaos zones

In those first three days, you are your own lifeline.

Step 1: Secure Your Shelter

Before food or water, make sure you’re safe from the elements and threats.

Bug-in? Check windows, lock doors, and seal drafts
Bug-out? Move fast to a predetermined safe location
Have tarps, blankets, and plastic sheeting for insulation or emergency repairs

If roads are dangerous, stay put unless absolutely necessary.

Step 2: Water Comes First

The human body can survive weeks without food—but only 3 days without water. Plan ahead:

Store at least 1 gallon per person per day
Use collapsible containers or fill bathtubs if you have warning
Have filters (Sawyer Mini, Berkey, Lifestraw) and purification tablets

Urban preppers: avoid open sources near sewers or industry unless filtered.

Step 3: Feed to Function

Choose foods that are ready-to-eat, calorie-dense, and shelf-stable.

MREs, freeze-dried meals, protein bars, canned beans, peanut butter
Manual can opener (non-electric)
Solar oven or small butane stove if cooking is required

Eat what fuels you—don’t rely on junk calories during high-stress periods.

Step 4: Stay Informed Without the Grid

Knowledge is power—especially when infrastructure fails.

NOAA hand-crank radio with emergency alerts
Printout maps and contact lists (don’t rely on your phone)
Use walkie-talkies or GMRS radios for local communication

Step 5: Light, Warmth, and Sanitation

These 3 comfort factors quickly become survival needs:

Lighting: Flashlights, headlamps, LED lanterns (and extra batteries)
Warmth: Mylar blankets, wool socks, emergency bivy bags
Hygiene: Baby wipes, bucket toilet, trash bags, hand sanitizer

Morale matters. Don’t underestimate the psychological value of being clean and warm.

Step 6: Defend Yourself (Legally and Discreetly)

Chaos breeds crime. Stay alert and prepared without becoming a target.

Know your local self-defense laws
Have pepper spray, a tactical flashlight, or non-lethal alternatives if firearms aren’t legal
Establish a simple perimeter watch routine—especially at night

Step 7: Get Organized and Take Notes

Use a notepad to document:

Water usage
Meal plans
Supplies used or broken
News updates from radio or neighbors

It helps reduce panic and keeps your mind focused on next steps.

Conclusion: The First 3 Days Define the Rest

Disasters don’t give warnings. That’s why having a 72-hour emergency plan is non-negotiable. You may not be able to control what happens—but you can control how ready you are to respond.
