S 1.9 Fire sealing of trays
Initiation responsibility: Head of Site/Bldg Technical Service; site fire
protection officer
Implementation responsibility: Site/Bldg Technical Service; site fire
protection officer
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 fireplace
(chimney). Smoke and fire would have spread to all floors in no time.
Additional controls:
- Has the person responsible for fire protection been consulted with regard to
route planning?
- Have possible alternatives been explored as regards line routing?
