Abstract

The article substantiates the urgency of improving the means of orientation in a smoky environment, which is to reduce the time spent by rescuers in a non-breathable environment when performing tasks in extreme situations. The aim of the work was to develop an ultrasonic orientation system in a smoky environment and analysis of the results of the experiment in the smoke chamber to identify the effectiveness of its work. Modern additional means on fire helmets to improve orientation in a smoky environment were analyzed. The analysis showed that lighting equipment is most often used on helmets, thermal imaging cameras and a headset for radio exchange are used less often. The use of ultrasonic gas shields and its effectiveness as an auxiliary system for orientation in a non-breathable environment has not been studied. The description, structure and theoretical calculations of the ultrasonic system are given. An experiment was conducted, which proved the effectiveness of the developed ultrasonic orientation system in a smoky environment.
