Improving the effectiveness of the protective properties of filter respirators due to their treatment with impregnating solutions

this article discusses solutions to the problem of the harmful effects of dust on the health of workers of mining enterprises conducting open-pit mining operations. Industrial dust has an irritating, fibrogenic, allergic and carcinogenic effect, and its particles of 0.1—3 microns in size are able to settle and accumulate in the deepest parts of the respiratory tract. The increased incidence of pneumoconiosis among workers of the mining complex persists to this day, despite a sufficiently large number of existing methods used to reduce the concentration of dust in the workplace. In this regard, a method is proposed to protect personnel from exposure to industrial aerosol by selecting a solution for the treatment of personal respiratory protective equipment. It is proposed to use glucose and polyvinyl acetate as components of the impregnating solution. As a result of the research, the dependence of the concentration of granite dust in the undermask space of the respirator on the mass content of the components used in the impregnating solutions was established. The use of 15% glucose solution or 10% polyvinyl acetate solution for impregnating respirators can increase the efficiency of dust capture by 80% without significantly increasing the resistance to inhalation and exhalation and reduce the risk of developing professional respiratory diseases.

Keywords: technosphere safety, labor protection, open-pit mining, dust, industrial aerosol, personal protective equipment, respirators, polymer solutions.
