New construction in Switzerland

“safety barriers on the side, with a height of 2m50cm - which in our studies of suicide hotspots has been found to be necessary to prevent people from crossing it. The barriers are slightly tilt towards the centre so that climbing it is practically impossible. “> Prof. Dr.med.
