At the outer edges of a building and at larger openings on a structural component area at least a 3-part side protection has to be provided if the fall height exceeds 2.0 m and the distance to strong structural components is more than 0.3 m. Unless a side protection can be fitted, the fall of persons or the dropping down of subjects must be prevented by providing safety (catcher) stands, protective walls or catcher nets which substantially extend up to immediately underneath the fall-down edge.
