Is emergency opening for blinds on the upper floor absolutely necessary?

The house is a few weeks before handover...

I will talk to the GC about it...

Strange that it was not criticized in the approval process. Possibly something will still come up during the acceptance inspection by the authority, if there is such an inspection.

Do you have shutters everywhere upstairs?

Yes, there are really blinds everywhere above.

Is there definitely an acceptance from the [Amt]?

No one from the authorities came by for the inspection. However, in the building application, a window (in the bathroom) is explicitly designated as an escape window, and at 1.87 x 1.43, it is also larger than the other non-floor-to-ceiling windows. In my case, the window also received a hand crank, but this is not mentioned in the building application; it came from my construction company.

How must an escape route be marked?

Are there standards for this?
I definitely can't find anything about it in our plans from 2017.
