It is proposed to consider the device of an integrated ventilation system that combines local exhaust welders' workplaces and general premises as main direction normalizing parameters air environment when performing arc welding. When organizing welding rooms limited dimensions, it necessary have possible effect drift flows. increases a result joint operation devices. The effectiveness devices f...

The paper considers modernization of the construction industry to be a priority aspect future development Ukraine and outlines importance quality competitiveness products ensured by training specialists. article analyses scientific research, which indicated need improve students' training. Special attention in is paid vocational (and technical) colleges, today's realities remain leading establi...

In order to evaluate the relationship between the concentration of welding fumes and cigarette smoke on the bronchopulmonary system function, a comparative study of spirometric measurements in 100 welders and 50 healthy volunteers was performed in an automobile manufacturing company. Two groups of workers were matched according to their age, height, smoking habit, years of service and soci...

The fibrogenic potential of 11 different welding fumes and metallic aerosols, considered to be reference standard surrogates for the commonly used welding technologies and applications responsible for 70% of welders exposure, is screened by using the rat peritoneal macrophage (RPM) in vitro bioassay. Only one class of fumes, that from the manual metal are welding of stainless steel, shows disti...

Welding is an important process used in the iron based industries. About two percent of the working population is engaged in some type of welding. The procedure of welding is simple but its health implications are complex. Welding generates enormous amounts of gases and metal fumes. Depending on the substrate and welding type, the composition of resultant gases and fumes changes. Therefore, wel...

To clarify the relationship between morphological changes in the corneal endothelium and ultraviolet (UV) radiation, specular microscopic examinations were performed on both eyes of 118 welders and 85 controls. The results showed: a decrease in the hexagonal cells in welders (20-29 years) in comparison with the controls (20-29) (p less than 0.05); an increase in the mean cell size of the endoth...

This paper reports a study into the levels of magnetic fields induced by arc welding equipment in various ways order to assess their impact on body welders. It is known that welders are exposed field high intensity. Depending technique and type equipment, it may exceed maximum permissible (MPL). Note new Ukrainian sanitary standards for have been introduced, which regulate depending frequency r...
