FEATURES OF THE ACTIVITIES OF GAS SMOKE PROTECTORS IN THE CONDITIONS OF POSSIBLE COMBAT DAMAGE

Abstract

It is noted that the rare facts of the death of rescuers during the performance of assigned tasks, in particular in the conditions of possible combat damage, indicate that the study of the indicators that characterize the activity of gas and smoke protectors during emergency rescue operations in such conditions is an urgent scientific and practical task. The conducted analysis showed that an important and unsolved part of the problem of conducting emergency rescue operations by personnel in conditions of possible combat damage during the war is the absence of quantitative indicators characterizing the relevant patterns of gas and smoke protection activities. Statistical analysis of the obtained experimental results, which were obtained during the execution of certain control exercises in a random sequence (climbing an endless staircase, a traction simulator, a treadmill, an exercise bike, overcoming a thermal smoke chamber-labyrinth in a smoky environment under conditions of elevated temperature (up to 60 ͦС) and limited space) in a mobile simulator produced by MAW GmbH, which to date most fully reproduces the working conditions of fire-rescuers in a non-breathable environment, allowed a new scientific result to be obtained. For the first time, it was determined that the regularities of gas smoke protection devices in conditions of possible combat damage, when they are additionally equipped with body armor, are characterized by the fact that their distribution is described by a normal law. This made it possible to use the Student's test for dependent samples with a significance level of a=0.05 to obtain both the performance indicators of the personnel, the differences between which in the case of operational activities in body armor are significant, and the indicators, the differences between which can be considered insignificant. It was noted that in the course of experimental research, the time for completing the assigned task after using a bulletproof vest of the 3rd class of protection practically did not change. However, in the conditions considered in the experiment, even only due to the increase in the weight of the equipment and the complexity of the work, all psychophysiological indicators that characterize the condition of the rescuer significantly worsened. Indicators for a simplified assessment of the working time of gas and smoke detectors are proposed.
