Abstract
The article studies the dependence of the human flow density on two main parameters: the width of the staircase and the number of people on the floor. It was established that violation of standards in terms of the entrance door width and the presence of a stair hall have a strong influence on the total time of evacuation due to the formation of clusters. The tabular dependence of the maximum human flow density on the staircase width on the number of people per floor was obtained. On the basis of this dependence, the graph was built, which can be used in the stair width design, taking into account the allowable human flows density in the case of known average number of people on each floor of the building.

Nowadays, there is a negative tendency to thoughtlessly close the various gross violations of regulatory fire safety requirements by fire risks calculation during the building construction, especially commercial objects
The article shows the influence of the staircase hall presence in front of the entrance door and the doorway width on the human flow density and the estimated evacuation time
Summary
There is a negative tendency to thoughtlessly close the various gross violations of regulatory fire safety requirements by fire risks calculation during the building construction, especially commercial objects (business centres, shopping and entertainment complexes). These buildings are concentrators of large human clusters, additional requirements should be placed on them in terms of space-planning decisions [1], fire safety of structures [2,3,4,5] and measures of their additional fire protection, as well as control of its application [6,7,8,9,10,11,12]. This study could help to the further improvement of the regulatory rules in terms of minimum width permission of the staircases, paying attention to the dependence on the people per floor number
