This paper presents models of firefighting operations of fire brigades from the point of view ofassessing the fire risk of buildings. The following seven related standards can be distinguishedworldwide: International Fire Code (IFC), NFPA 5000: Building construction and safety code,International Fire Engineering Guidelines (IFEG), Fire Risk Evaluation and Cost AssessmentModel (FireCAM), Fire Evaluation and Risk Assessment system (FIERA), PD 7974-5:2014Application of Fire Safety Engineering Principles to the Design of Building; Part 5 Fire and RescueService Intervention as well as a Fire Brigade Intervention Model (FBIM). Given the editoriallimitation as to the amount of text only the last one of them, which was used to the greatestextent in the construction of own model, was discussed in detail. The others have been discussedonly in a general way. In the final part of the work, the existing models were evaluated as partof the discussion. On the basis of a critical review of literature and own research of the authors,a stochastic model of firefighting activities of fire brigades in Poland was developed, which will beone of vital elements of the Aamks software developed at the Fire Safety University for assessingthe fire risk of buildings. The description of this model along with the results of its operation andtheir discussion will be presented in the successive parts of the same series.
