I am interested in doing a Quantitative Risk Assessment for a building. But the historical data of past fire occurrences for that building is not available? What value should I take? I am unable to get it from literature also. Please suggest.
If the building doesn't have an historical data of the latest fire scenarios, you should consider same kind of building statistics. FRA Analysis from SFPE could help a lot.
If the historical data of past fire occurrences for that building is not available, you can the same for similar type of building from official site of
Ministry of Home Affairs (India) and other govt official sites. you can also get such data from UK-HSE.
While taking the data please insure the building classification as per NBC-Part 4, material stored, fire loads, building design, date of construction etc should be matches otherwise change the data accordingly.
