Contributions to risk injury evaluation of human skin contact caused by welding technology in mechanical engineering a company

Abstract

Abstract.Assembly by welding is a very important pollutant technological process, mainly of the atmosphere and soil. The formation of gas in welding process is the result of electrodes, fluxes burning, formation of fused bath and welded seam. A large number of human operators feels different adverse effects on health. Most problems appears in respiratory system and include bronchitis, respiratory irritation, fever caused by smoke, changes in lung function, decreased immunity to infection and a possible increase of lung cancer risk. Very little information are available about effects on the organism and skin after exposure to fumes from welding, therefore. In this order, this paper do a risk assessment by skin contact. Starting from the main parameters for the evaluation of a cutaneous risk, it was determined a score of danger, a score of surface and a score of frequency. It results a risk associated with each class with a value Scut = 100.000, that indicates a very high probable risk with immediate proposing corrective measures.
