Abstract
Objectives The environmental factors at the fire that affect the efficiency of the operational activities of fire and rescue units in an unfit environment for breathing and statistical information on the functioning of the gas and smoke protection service in regions of the Russian Federation are given. Method The methodology for conducting experiments with groups of reconnaissance to search for an injured firefighter is given. A description of the location of the experiment and the algorithm for the movement of reconnaissance groups are presented. Result Results of experiments on the actions of the units of gas and smoke protective service inside fire object on search of the injured firefighter who is in unconsciousness are given. The experiment was conducted in the conditions of premises without lighting and with influence of noise hindrances to staff of groups of reconnaissance. The results of the experiments confirm the need of identification of firefighters at the site of a fire by of sensors of a motionless state and light reflecting elements of clothes and equipment. The results of the experiments are correlated with previously conducted experiments to study the time of fire reconnaissance in the premises of residential and public buildings. The necessity of the research of the parameters of the work of groups of reconnaissance at various sites on the basis of the temporal parameters of the work of gas and smoke defenders has been determined. Conclusion The positive influence of the presence factor of immobile sensors in the personnel of fire and rescue units operating in conditions unsuitable for breathing environment has been established. The proposed directions for the research of organizational systems for the management of fire departments at the fire.

Summary
The positive influence of the presence factor of immobile sensors in the personnel of fire and rescue units operating in conditions unsuitable for breathing environment has been established. Исследование включало следующие виды измерений: 1) измерение эргономических особенностей применяемых датчиков неподвижного состояния (увеличение охвата талии газодымозащитника при размещении устройства на поясе); 2) измерение времени нахождения и эвакуации газодымозащитника, находящегося в аварийной ситуации [11]; 3) измерение уровня звука аварийного сигнала датчиков в помещении [12]; 4) измерение уровня звука аварийного сигнала датчиков на открытой местности [12]. Звенья ГДЗС, осуществляющие поиск пожарного, не оснащенного датчиком неподвижного состояния, проводят разведку алгоритмом «по периметру» каждого помещения [14] с произвольным выбором стороны обхода (рис.). Звенья ГДЗС, осуществляющие поиск пожарного, оснащенного датчиком неподвижного состояния, проводят поиск по факту восприятия световых и звуковых сигналов датчика и могут двигаться не проверяя помещения, в которых отсутствуют признаки нахождения пострадавшего пожарного (нет световой и звуковой сигнализации датчиков). Замер времени поиска пожарного осуществлялся с момента входа звена ГДЗС в локацию объекта пожара до момента нажатия кнопки аварийной подачи воздуха на ДАСВ пострадавшего. Время полной эвакуации измерялось от входа звена ГДЗС в локацию объекта пожара до выноса пострадавшего на свежий воздух
