3 days ready at home

The Danish authorities say every home should be able to manage on its own for 3 days in a crisis. That is the whole plan. The rest of this page shows what it takes.

Why this page exists

Tuesday, late afternoon

It is Tuesday. The power is out.

The dishwasher stops mid-cycle. The fridge hums oddly, then not at all. The router light goes dark. Your phone says 23%. At the supermarket the card terminal shows an error and the queue is not moving. Nobody knows if this lasts an hour or a week. The authorities ask one thing: every home manages on its own for 3 days, so help can go first to the hospital, the care home and the people who really need it. That is the whole idea behind this page. Not bunkers. Not towers of tinned food. A few things in the cupboard and a plan you can explain to your mother-in-law.

If something happens

When the siren sounds

  1. Step 1

    Go indoors

    Come inside and stay inside. Close windows and doors.

  2. Step 2

    Get information

    Listen to the news. A battery or wind-up FM radio works when the internet does not.

  3. Step 3

    Follow the advice

    Do what the authorities say. Check a source before you share news, so rumours do not spread.

  • Cooking without power

    Outside only

    A camping stove or barbecue can boil water. Never use it indoors or in a closed space. Smoke and carbon monoxide are dangerous.

  • Call 112

    Real emergencies

    Keep the line free for life-threatening calls. If 112 is down, the authorities will announce other numbers.
