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.
