Abstract
The article discusses the regulatory requirements for security zones, especially for the calculation of its area. Using the example of the Three Sisters rehabilitation center, located in the Moscow region, the actual required area of the security zone required for one person of the M4 population with limited mobility is considered. The number of patients with reduced mobility in rehabilitation insti-tutions exceeds at least twice. The evacuation of the M1-M3 mobility groups is considered via stairwells directly to the outside. Fullscale observations of the evacuation of people along horizontal paths to the safety zones were carried out to establish the evacuation time and the capacity of the safety zones. In the Pathfinder software product, a three-dimensional computer model of the buildings of the protection object was developed, taking into account the data obtained from field observations to assess the safe evacuation of people.
