ALGORITHM FOR CALCULATING THE MOVEMENT OF GAS-SMOKE PROTECTION SERVICE UNITS DURING GROUP RESCUE OF PEOPLE FROM UNBREATHABLE (SMOKEY) ENVIRONMENTS

Voronov Maksim A., Ishchenko Andrey D.

The main reasons for group deaths in a fire are blocking escape routes due to loss of visibility in combination with complex escape routes, as well as the absence of openings with an exit directly to the outside. The only way to rescue in this situation remains rescue with the help of gas and smoke protection service units through complex evacuation routes, which imposes certain restrictions on the number of people that can be saved. An algorithm for calculating the movement of gas and smoke protection service units during group rescue of people from an environment unsuitable for breathing (smoky) is presented. It is noted that to describe more complex routes, it is necessary to use a network graph model, where each of the rescue options will be calculated by the presented algorithm.
