Abstract


In the engineering industry, metals and alloys used in the manufacture of metal products and structures are subjected to welding processes, which can release metal vapors, harmful dust and particles into the air, with negative effects on workers' health and the environment. Some joining methods generate hazardous gases, categorized as greenhouse gases, toxic gases, flammable gases and explosive gases. There are clear regulations on the permissible limits for concentrations of metallic and non-metallic particulates and gases emitted by various industrial processes, including welding. The aim of this research was to measure chemical agents in the workplace air as well as respirable and respirable dust concentrations in the workplace atmosphere at a company in the Semi-Fabricated Joining Section for the position of a manual electric welder. The determinations of chemical agents and of respirable and inhalable dusts were carried out in the workers' breathing zone between 0800 and 1400.
