Laws and Regulations Welding

Lower exposure limits for smoke and fumes from welding and metal cutting

International health organizations recognize the importance of preventing health risks associated with fumes and smoke generated during welding and thermal cutting. In many countries, strict personal exposure regulations and standards such as ISO Limit Values, OSHA PEL and ACGIH TLV are heavily enforced to minimize worker exposure to hazardous metal particulate that can be present in welding fume.

Ventilation and filtration are the primary solutions to mitigate employee welding fume exposure. Welding fume is generated by a thermal process that creates a plume of suspended particles in the ambient air. When the fume plume cools, the particles enter the breathing zone affecting worker exposure. Properly designed capture and filtration systems protect worker´s health and assist in complying with local regulations and standards.

    The health risks of welding fume, and how to reduce them in the workshop

    In 2017, the International Agency for Research on Cancer (IARC) released new scientific evidence showing that exposure to mild steel welding fume can cause lung cancer, and possibly kidney cancer, in humans. As a result, mild steel welding fume has been reclassified as a human carcinogen in the United Kingdom, and it is likely that other countries will follow suit. Moreover, this recent discovery indicates that all welding fume should be seen as potentially carcinogenic, and that measures will need to be taken in order to reduce the health hazards caused by welding fume exposure.

    The benefits of smart and communicative filter systems

    IoT technology and artificial intelligence are reshaping industrial processes. By gathering data, applying analytics and extracting insights, companies can understand, monitor and maintain the performance and quality of their systems like never before. This is certainly the case with industrial filters as well.
