The hum of operating equipment and the whistle of ventilation can be heard here, creating the feeling that you are somewhere close to an active production facility, although the premises themselves look abandoned.

The walls of this level are made of grey concrete and the floor is covered with an oily film, making it slippery and unsafe to walk on. The lighting here is very abrupt: dim lamps flickering on the ceiling create a tantalizing atmosphere where the shadows seem very long and ominous. At times you felt like someone was watching you, and this feeling persistently followed you throughout your stay.
