The metal industry produces all sorts of contamination - welding fumes, grinding dust, oil mist etc. The welders and personnel in work areas are exposed to these contaminants. It is therefore essential to create a healthy and safe working condition, by reducing these risks to health. Protective measures are an important aspect of this. So important, in fact, that strict international standards have been established to regulate them. Welding fumes, small particles and remains of molten metal, must be dealt with effectively, by means of efficient extraction and filtration system. This ensures that workers feel better, enabling them to perform better. The result is higher productivity and lower absenteeism.
