Abstract.
Objectives. To make an integrated hygienic assessment of the working conditions of employees exposed to aerosols of man-made mineral fibers.
Material and methods. The research was conducted at the workplaces of the shop manufacturing heat-insulating boards of mineral wool based on basalt fiber of one of the largest enterprises in the Republic of Belarus for the production of building materials. To study the peculiarities of employees working conditions we used the data of industrial laboratory control, the results of our own research on factors of working conditions and labor process. The integrated hygienic assessment of working conditions was made using certification data on workplaces. The calculation of dust loads and the permissible length of service was based on the average content values of mainly fibrogenic aerosols obtained during the production laboratory control.
Results. The complex of hazardous occupational factors, exerting influence on the employees of the shop of heat-insulating products has been determined, their qualitative and quantitative characteristic has been given. The integrated hygienic assessment of working conditions has been made, classes of working conditions according to the main occupations of the manufacturing workshop have been established. Dust loads and the permissible length of service in contact with fibrogenic aerosols have been calculated.
Conclusions. Working conditions at workplaces of 16 out of 17 professional groups of workers of the heat-insulating materials manufacturing workshop don’t comply with hygienic standards and are harmful, including working conditions for 13 professional groups that correspond to class – 3.2, for two professional groups – to class 3.3. and for one – to class 3.1. The main production factors causing harmful working conditions at the workplaces of the manufacturing workshop are chemicals in the air of the working area, dust and fibrogenic aerosols and production noise. Dust loads for all professional groups of the manufacturing of the heat-insulating materials based on basalt fiber don’t exceed the control ones for the studied length of service, and the excess of the permissible length of service in contact with silicon-containing dust was found in solitary cases.
Key words: working conditions, hazardous occupational factors, mineral wool manufacturing, man-made mineral fibers, industrial aerosols, integrated hygienic assessment of working conditions, dust loads, permissible length of service.
