Sažetak

A survey is given on health problems at welding. Potential hazard from nitrous oxides, ozone, carbon monoxyde, fumes of lead, zinc and cadmium and the fumes containing iron oxides, amorphous silica and oxides of calcium and manganese arc described. The irritative effect of fumes at arc welding with basic (low hydrogen) electrodes is believed to be due to the content of fluorine in the fumes. The maximum allowable concentration of arc welding fumes have been proposed to 20 mg/m3, at are welding with basic electrodes 10 mg/m3. The welders' flash and its prevention are discussed. X-ray or radioactive isotopes used to control welds may also create a health hazard. It is pointed out that the most important accident risk at welding is the hazard of explosion at welding on drums, barrels etc. containing explosive or flamable material. The role of the Commission on Hygiene and Safety of the International Institute of Welding is described.
