Complex welding technology requires understanding in the formulation, execution, use of welding consumables, fume emission during welding and application of protective equipment and devices. The approach to the importance of the liquid metal-slag reaction problem, except from a technical point of view, is based on the assessment of the existence of harmful substances and their impact on human health. The assessment includes gases and particles contained in welding fumes, which are known in the industrial medical sciences for their irritating effect on the skin and mucous membranes, toxic or carcinogenic effects or potentially causing allergic reactions for which a limit value has been defined. This is the foundation on which harmful substances are defined in the next step in industrial medicine. Although modern technology has made great strides using robotic welding, robots cannot do everything, so steps need to be taken to protect the welder and help eliminate the risks they will face during their working life. Global occupational safety experts provide advice and find engineering solutions to eliminate the hazards of harmful consequences caused by the workplace welding process. For areas where this is not possible, personal protective equipment (PPE) is considered the final solution and is crucial to protect employees from exposure and injury caused by known risks. The key areas on the welder’s body that PPE needs to protect are the hands, skin, eyes, face, legs, hearing, and airways. PPE parts are often made of natural leather and a combination of leather and other materials.
