Abstract
The variety of architectural solutions of buildings and the multitude of purposes to which they will be used enforces the use of solutions not directly provided for in the law. To ensure an adequate level of safety are used replacement and substitution conditions. The currently functioning system of expert opinions is based on expert knowledge, which is often difficult to assess and gives divergent solutions for similar cases. Development of an objective and repeatable method of matching optimal solutions to the threat of fire is an area of current research in the field of fire safety engineering. The subject of the work covered the process of determining the scenarios causing the greatest threat while estimating the probability of its appearance. Using the multisimulation method - multiple simulations for a given object with determine variables is established the probability distribution of specific negative events. Variables are drawn based on distributions developed with statistical methods from historical data. The method is based on the known input data - British Standards and with keeping a sufficiently large number of draws gives reproducible results - probability distributions. In addition, the model can be expanded with new variables and adapted to atypical issues.

The variety of architectural solutions of buildings and the multitude of purposes to which they will be used enforces the use of solutions ensuring safety not directly provided in the law
It is not by coincidence that conditions are comparable and not the same. This is due to the fact that no two solutions are able to give the same results, taking into account the random nature of the risks associated with the creation and development of a fire
The second stage is approval by the appropriate authority, this is the local headquarters of the State Fire Service
Summary
The variety of architectural solutions of buildings and the multitude of purposes to which they will be used enforces the use of solutions ensuring safety not directly provided in the law. It is not possible to predict, by any legal system, sufficiently detailed regulations ensuring, in given circumstances, an appropriate and economically justified level of safety for building users. For this reason, the legislator, by creating regulations, set general rules that should be met by buildings. It is not by coincidence that conditions are comparable and not the same This is due to the fact that no two solutions are able to give the same results, taking into account the random nature of the risks associated with the creation and development of a fire. This process takes place in two stages. In the further part of the study, the authors presented proposals for assessing the safety level of a building in which one of the most popular replacement solutions is used
