The 72-Hour Home Emergency Kit
The 72-hour home emergency kit is different from a go-bag. The go-bag is designed to be grabbed and carried during an evacuation. The home kit is a larger, more comprehensive supply designed to sustain the household in place for three days when the normal supply chain fails — when the shops are shut, the power is out, and you cannot leave.
Most emergency preparedness agencies (FEMA, American Red Cross, UK Cabinet Office) recommend a minimum of 72 hours of supplies in the home. This covers the most common emergency scenarios — winter storms, power outages, flooding, and the acute phase of most crisis events.
The Scope Difference: Go-Bag vs. Home Kit
| Feature | Go-Bag | Home 72-Hour Kit |
|---|
| Purpose | Carry during evacuation | Sustain at home |
| Size | Portable (10–15kg) | Fixed; can be 30–60kg+ |
| Food | 3 days calorie-dense, compact | 3 days full household supply |
| Water | 1–2L (supplement with purification) | Full 3-day supply (3.8L/person/day) |
| Shelter | Emergency blanket | Already have home |
| Organisation | Single bag | Dedicated storage area |
The home kit allows more comprehensive supplies because weight and portability are not constraints.
Water — The First Priority
For a family of 4, a 72-hour water supply is:
- 4 people × 3.8L/day × 3 days = 45.6 litres
Storage options:
- 12 × 4-litre sealed containers (48L)
- 1 × 50L HDPE drum
- Individual 2L bottles (24 × 2L)
Store in a cool, dark location. Replace every 6–12 months. See the water storage article for full guidance.
Food — Three Days, All Household Members
| Category | 3-Day Supply (Family of 4) | Storage Form |
|---|
| Carbohydrate | 3kg rice or pasta | Sealed; cool |
| Protein | 8–12 canned fish/chicken/beans | Normal shelf |
| Fat | 500ml oil | Cool; dark |
| Snacks | 2kg nuts/dried fruit | Sealed |
| Ready meals | 4–8 camping pouches or MREs | Normal shelf |
| Infant/child specific | Formula, baby food, cereal as needed | As required |
Eating sequence in an emergency:
- Use fresh food from the fridge first (before it spoils in a power outage)
- Move to frozen food (safe for 24–48 hours in a powered-off freezer)
- Use shelf-stable supplies
