Ccps - ignition frequency and reliability
WebIgnition 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. Webmethodology allows to have for each ignition source the largest experience feedback and improves the reliability of the results. For each reference group, a fire frequency is obtained from the operating experience with the following formula: T where Nf is the number of fire events related to the equipment of the reference group and T is
