9.5.11 Management actions required to maintain
means of escape
have been some notable incidents where the fi xed fi re
fi ghting system in a building has been extremely suc-
cessful in controlling and extinguishing a fi re that the fi re
service has not been able to deal with.
At the design stage architects may consider the
provision for FFS as a compensatory feature to provide
additional protection to a large space or vulnerable part
of a building. FFS are occasionally 'retro' fi tted to existing
buildings to mitigate a historic weakness or reduce the
perceived fi re risk of a change of use or circumstance.
The benefi ts of providing active FFS include:
Persons responsible for fi re safety within buildings will
need to ensure that the means of escape within their
area of responsibility is maintained so as to be available
at the time when it is required.
It is normal for the elements that comprise the
means of escape of a building to form part of a more
comprehensive fi re safety management system. A com-
prehensive system will include the competent testing of
fi re safety systems including systems that detect and
give warning of fi re.
Table 9.11 outlines those actions that managers and
responsible persons will need to ensure occur together
with examples of typical time frames.
