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.

This article analyzes the reasons of temporary disability of laborers in Agro Industrial Complex, dealing with microbial content in industrial premises. Development and implementation of equipment for correction of microbial content level results in reduction of general morbidity rate and duration of temporary disability among laborers in Agro Industrial Complex. It will help to increase labor efficiency and decrease labor intensity of production. Biofilm resistance against antibacterial agents is a vital problem during disinfection treatments. Increase in bacteria survival potential and reduction in sensitivity to the substances eliminating them, results in need for increased dosing of the latter decreased efficiency of sanitation. This is a stimulus to develop alternative antibacterial compositions and methods of disinfection treatment. The basic difference of the suggested photodynamic treatment from the disinfection methods with application of antimicrobial preparations is the lack of resistibility to destabilizing oxidant – singlet oxygen. Before disinfection treatment, we determined total microbial air contamination according to the original method, providing a possibility to use air medium sampling of the total volume of indoor area. Experimental results have shown a decrease in total microbial contamination by a factor of 5.5 on average.

The design of an ultrasonic aerosol device with increased reliability has been developed. For air treatment the method of aerosol disinfection is offered, as a result of which the general microbial semination of premises is reduced in the average 5,5 times, the content of mold fungi - in 11 times.

The role of tissue hygroscopicity in violation of the protective qualities of tissues made of natural fibers, associated with increased tissue permeability by microorganisms, is shown. The ability of the studied tissues to absorb moisture was determined. An original program was used to assess the hygroscopicity of fabrics intended for the manufacture of special clothing. Recommendations have been developed for the use of cotton fabrics in conditions of high microbial contamination.

The article provides the results of studies of the working conditions and safety of workers of pig farms and. The quantitative indicators on harmful gases present in the air are reflected, as well as the normalized parameters of the working time regime. The effect of these working conditions on morbidity has been noted; typical types of morbidity as a result of these working conditions are named. It is reflected the need for further work in its direction, the use of which will reduce and, subsequently, eliminate the injury of pig-breeding operators.
