Abstract
Ignition frequencies and ignition frequencies per floor area were
determined for different building categories in Finland as total groups
and as a function of the floor area of the building. These frequencies
are needed as input for risk analysis using performance based fire
safety design. It was found that differences between building categories
or location within country were so small that a universal curve for the
whole country could be determined. For ignition frequency per floor
area for small buildings a strong dependence on size is observed, but it
remains approximately constant for larger buildings. Additionally
periodical variations of ignition frequency of buildings by month and
week of year, day of week, and time of day were determined. Historical
review of the development of ignition frequency models was made. Some
evaluation on the generality of the results was made based on the
theoretical models.
