For this reason, the BFB recapitulates in a press release the most important rules that should apply to both tenants and owners:

In case of fire, building entrances, staircases, corridors and forecourts become escape routes for the
residents. For the fire department, ambulance or police, in turn, they are escape routes. Therefore it is
essential that these places are safe and free of combustible materials.

• Entrances, staircases, intermediate landings, niches, storage spaces under stairs, corridors
  and forecourts must be kept clear and safe to walk on at all times. They may not be used for any other
  serve. An apartment may not be extended into the stairwell.
• The passage width must be at least 1.20 m and remain free of objects.
• In apartment buildings, main entrance doors in the direction of escape must be locked at all times without a key.
  can be opened.
• Items such as baby carriages, bicycles, furniture and wardrobes do not belong in the stairwell.

  Floor coverings, large-scale pictures, etc. made of combustible materials.
