2.3.6. Parking garages
A fire in an enclosed garage can very quickly create a
dangerous situation for all people in that area. Due to the
significant fire load of the parked cars, a fire which is not
detected and suppressed early can develop into a fire
that will be very difficult to extinguish and may threaten
the stability of the building.
Deceptive phenomena such as exhaust emissions and
the harsh environmental conditions not only affect early
and reliable fire detection but also affect the service life
of ordinary fire detectors. For this reason only fire
detectors which respond appropriately to such deceptive
phenomena and which were developed especially for
harsh environments are installed in parking garages.
More detailed information regarding fire detection in
parking garages is given in the document
“fire detection
in parking garages”.
2.3.7. Plant rooms
Plant rooms, in which power supply, control systems,
security systems and IT infrastructure are
accommodated, are risk areas that need to be especially
protected. This applies particularly to fire safety in these
areas.
Aspirating smoke detection systems (ASD) are able to
detect even the smallest aerosol concentrations. They
can detect extremely low smoke concentrations which
may be caused, for example, by a malfunction of an
electrical or electronic component. It is possible to
prevent fire developing simply by removing the power
from the particular unit.
More detailed information regarding fire protection in
plant rooms is given in the document
“fire protection in
plant rooms”.
