This master thesis deals with detailed analysis of fire safety in the Elementary school of Tomo Brejc, which has recently been renovated. In the first part of the thesis fire measures for theanalysed building are designed according to the prescriptive approach, i.e. Slovenian technical guideline TSG-1- 001:2010 is used. Afterwards designed fire measures are compared with the actual condition. The designed fire measures are presented in the fire safety study. The second part of the thesis includes a comparison between fire – safety measures determined in the first part and fire measures designed according to German technical guideline MBO 2002, which was used in actual design of the discussed school. Differences between both guidelines are given, and advantages and disadvantages of Slovenian technical guideline’s TSG-1-001:2010 are pointed out. The last part of the thesis presents a detailed analysis of evacuation routes in the classroom part of the discussed building. Performance based approach is used, i.e. advanced computer softwares Pyrosim and Pathfinder are used. On the basis of the simulation results the suitability of evacuation routes in the classroom part of the school is estimated.
