Performance-based fire safety engineering (FSE) is an
important tool for constructing fire safe environments.
The efficiency of such a tool is dependent on several
areas of knowledge, such as the behaviour of humans in
relation to fires and of course the nature of the fire
itself. However, much of the necessary information for
using the FSE tool efficiently is today either lacking
or poorly understood. A fire hazard analysis is of
course relying on the assumptions of fire growth that is
done by the engineer. The time scale for the fire is
depending on the selection of the design fire and this
time scale will in most cases determine the time for
further fire spread, the probabilities for casualties,
the time available for escape and so on. Therefore, the
method to arrive at a plausible design fire has been the
objective for much research work over the years.
However, methods that are envisaged internationally are
still simple and rather crude and needs to be further
improved to be more versatile.
