Abstract

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.

Highlights

One of the factors influencing the efficiency of labor potential utilization is sanitary-hygienic state of working environment, microclimate parameters, such as increased microbial content in production premises air space
The most widespread method of determination for air microbial content of indoor areas is calculation of microorganism colonies grown after incubation, free deposited from air on the nutrient medium of open Petri dishes
The test results can be argued in connection with localized sampling, and with the fact that small size and weight do not allow some bacteria getting into Petri dish

Summary

Introduction

One of the factors influencing the efficiency of labor potential utilization is sanitary-hygienic state of working environment, microclimate parameters, such as increased microbial content in production premises air space. Elements have different fixations in the devices: at variable or small flow of air the filter cloth typically produced from fabric, is placed in a frame, fixed by means of latches or thread joints.
