The provisions of the Federal Law Russian Federation dated 22.07.2008 No. 123-FZ "Technical Regulations on Fire Safety Requirements" stipulate possibility designing L1 type stairwells with open doorways in external walls. requirements regulatory documents necessity calculation substantiation design solutions to exclude blocking by fire hazardous factors spreading along facade. To test and analyze these requirements, this paper assesses influence different time such factors. Goals objectives. purpose is approve for protection from depending wind speed, functional hazard class burning premises, dimensions partitions projections stairwell, as well windows premises. Methods. Calculations intervals stairwell facade premises were based methodological mathematical models used determine risk. Results. calculated data allowing estimate walls speed area object location, peculiarities combustible load sizes obtained. These made it possible assess specifying requirements. Conclusions. Based research, formation necessary practical experience exclusion that spread are received. obtained make evaluate size projection its factors, directions specification
