WHEN THE POWER HAS JUST GONE OUT
What to establish first.
The lights go out and the router falls silent. First consider whether anyone is in immediate danger. Then establish the apparent extent of the interruption and check information from your local grid operator. This Germany-focused page gives a brief starting point and a blog post about seven avoidable mistakes. The blackout preparedness page covers equipment planning for later.
01Is it only my home?
Use a light you already have. Observe whether the stairwell or neighbouring buildings also appear affected, without putting yourself at risk. This is an initial observation, not a diagnosis. Contact the building manager or an electrician about your own installation. Do not open electrical covers.
02Where can I check an outage?
If you have a connection, check your local grid operator’s official outage service. Check the location and timestamp. The supplier on your bill may be different from the grid operator. Emergency numbers are for emergencies, not for asking when power will return.
03What can I do immediately?
Keep refrigerator and freezer doors closed as much as possible. Switch off appliances such as a cooker that was running, using their normal controls if safe. Coordinate with your household. For electrically powered medical care, follow the individual emergency plan; call 112 for an immediate threat to life.
