For evacuation, a person can comfortably carry 10-15 kg. Prioritize essentials if your reserve is heavier.
Plan your full household autonomy
Emergency autonomy depends on two pillars: water and caloric intake.
Water-food balance
Water always takes priority: without water you survive only a few days.
Priority order
- First 72 hours: bottled water and ready-to-eat food
- Days 4–7: rice, pasta, beans, water purification
- Beyond 7 days: freeze-dried meals, solar panels, water filters
