The causes of death of people during a fire, as well as the effect of toxic combustion products on the human body are analyzed. It was found out that the main problem of unhindered evacuation of people from the building is blocking the evacuation routes by smoke. Methods of fighting smoke in a fire are considered and their advantages and disadvantages are determined. One of the ways to solve this problem is ultrasonic coagulation of aerosols with subsequent precipitation. Effective coagulation of smoke in a fire can be provided by a piezoelectric ultrasonic oscillatory system.

Abstract: The article describes the theoretical and practical bases of formation of a regional system of monitoring technospheric security. Author's concept of a systematic approach to the solution of important scientific and technical problems. In particular, based on the literature review and the results of their own research found that for the purposes of implementing and monitoring the status of long-term forecasting of health and safety it is logical to apply the structure of the monitoring function of the feedback and the integrated forecasting, constructed using the principle of synergy of the elements.
