Hygienic Characterization of the Chemical Factor in Mechanical Engineering Enterprises

Abstract

All factors of the working environment, as well as the organization of work, which directly or indirectly may cause impairment of the health or performance of persons working in these conditions. To identify harmful factors, it is necessary to study working conditions and environmental parameters in production premises and directly in the work area, comparing them with accepted hygienic standards. The results of the analysis of air pollution of the main working areas show that a high concentration of the chemical factor was observed to be generated during the work process of the electric gas welding as well as the test drive. The reason for the high chemical factor in this enterprise under research is the installation of a non-rational ventilation system in workplaces and workshops, as well as the lack of rational use of the local intake system, low ventilation efficiency
