A prolonged power outage affects much more than just lighting. Internet, charging, cooling, heating, and digital payments can all become difficult at the same time. With a simple 72-hour supply, you can significantly reduce the impact at home.
In short
- Have drinking water, non-perishable food, light, and a radio ready.
- Keep power banks charged and reserve battery power for communication.
- Keep the fridge and freezer closed as much as possible.
- Never use outdoor burners, barbecues, or generators indoors.
- Make prior arrangements with household members regarding communication and vulnerable individuals.
What goes out during a power outage?
That depends on the home and the area. Lighting and wall outlets go out immediately, but central heating systems, electric stoves, routers, charging points, and some water supplies may also depend on electricity.
1. Drinking water
The national emergency kit checklist accounts for about 3 liters of water per person per day. For 72 hours, that is approximately 9 liters per person. In addition, store water for pets and special needs.
2. Food and cooling
Choose a part of your supply that can be used without a refrigerator and requires little preparation. Keep the fridge and freezer closed during the outage and follow official food safety advice if the outage lasts a long time.
3. Lighting
Preferably use LED flashlights or lanterns. Keep them in fixed locations and ensure you have charged batteries or spares. Using open flames as standard lighting increases the risk of fire.
4. Communication and information
Charge phones and power banks in advance. Use power-saving mode and check for information at set times. A battery-powered radio or other emergency radio can be a useful backup when the internet becomes less reliable.
5. Heat and cooking
Use layers of clothing and blankets when heating fails. Only cook with equipment intended for that purpose and in a safe location. A barbecue, charcoal burner, outdoor heater, or generator should never be used in a house, garage, or tent due to the risk of carbon monoxide poisoning and fire.
6. Payments and practical matters
Digital payments may be limited during an outage. Keep a modest amount of cash on hand and save important phone numbers outside of your phone as well.
