The paper considers the effect of sanitary and hygienic condition of occupational environment, namely the factor of increased microbial contamination, on temporary disability and reduction of labor efficiency. In this regard, it is necessary to improve the methodology and technical support of disinfection methods in order to reduce labor intensity and increase the efficiency of equipment and disinfectants. The developed deflector model serves to reduce the emissions of microorganisms into the atmosphere and improves the environmental situation. The proposed design of the ultrasonic system makes it possible to improve user experience due to the possibility to control the flow rate of the working fluid and preparations. According to the results of the experiment, the disinfection agent based on hydrogen peroxide, silver salt and a furocoumarin solution in ethyl alcohol with the use of the developed ultrasonic atomizer reduced the total microbial contamination by 8 times on average.
