In buildings with several fire cuts, it can hardly be avoided that trays will lead through fire walls and ceilings. After installation of lines, the breaches must be shielded in keeping with the fire-resistance value of the wall/ceiling. In order to provide for retrofitting, appropriate material (e.g. fire-resistant padding) should be used. The relevant VdS guidelines should be complied with.
Negative approach example:
In a multi-storey office building in Bonn, several networks were run through a common rising line from the basement to the uppermost storey. All ceiling breaches had been made with ample reserves, but had, after wiring and pipe installation, not been closed. In the basement, large quantities of paper and cloth were stored in the vicinity of the front end of the line. The rising line beginning immediately above would, in case of fire, have had the effect of a fire-place (chimney). Smoke and fire would have spread to all floors in no time.
