Welding & Cutting fume removal

    Using flexible extraction arms 06 May 2019

    At-source extraction protects workers in the metal industry and prevents the accumulation of welding fumes, oil mist or grinding dust in the workspace. The use of flexible extraction arms is a good method of removing dangerous fumes and dust when working on small or medium sized objects. These arms can be positioned close to the work area to capture toxic fumes, dust particles and remains of molten metal at the source. Capturing fumes and dust at the source also prevents pollution from spreading over the premises, keeping not only machines and tools but also products and offices cleaner.

  • Why airflow monitoring is important
    Why airflow monitoring is important 23 April 2019

    In previous blogs we have written about protection methods for welders, like extraction arms or hoods for local exhaust ventilation and welding helmets with PAPR units. When you provide your workers with protection equipment, you may think that you have taken the necessary steps to ensure their safety. But, how can you be certain that the equipment is working as it should and your workers are not exposed to dangerous levels of carcinogenic fumes?

  • New evidence: welding fumes can cause lung cancer
    New evidence: welding fumes can cause lung cancer 22 February 2019

    When metals are heated above their melting point, they vaporize and condense into welding fumes. Most people know that these welding fumes are unhealthy and dangerous. Although not everybody in the metal industry – and in other lines of work where welding is done – is fully aware of the dangers, most of them are familiar with local exhaust ventilation and personal protection equipment to minimize the health risks that are involved with welding.

  • Metal fume fever. What is it and how to prevent it?
    Metal fume fever. What is it and how to prevent it? 29 October 2018

    Metal fume fever is a benign, self-limiting occupational respiratory disease that results from the inhalation of fine metal particles. Whilst the exact mechanism for this condition is not known, the primary cause is thought to relate to the inhalation of zinc oxide fumes produced when zinc-coated steel or zinc-containing alloys (e.g. brass) are heated to high temperatures. A variety of other names for this condition is used, such as copper fever, brazier’s disease, welder’s ague, foundry fever, brass chills and spelter shakes.

  • Supplied air respirators provide the best all-around protection
    Supplied air respirators provide the best all-around protection 23 July 2018

    Welders must be protected against hazardous welding fumes. Depending on the welding environment or how and what is welded, welders can be protected by systems for source extraction and general filtration and ventilation. Also, they can be protected by respiratory protective equipment (RPE), such as welding helmets with fresh air supply. Supplied air respirators are known to provide the best all-around protection for the welders themselves.

  • Welders themselves see 'health' issues as longer term and thus less salient
    Welders themselves see 'health' issues as longer term and thus less salient 27 February 2018

    Nowadays, everybody knows that welding fumes are very dangerous and that all kinds of protective measures should be taken and respected during work. In other blogs on this site, you can read more about those dangers and risks. But is everybody really aware of the importance of those protective measures such as PPE and local exhaust ventilation? The answers of welders themselves are surprising…

    At source extraction is the recommended method for weld fume extraction 16 February 2018

    In buildings where welding is carried out, temperature control and problems of airborne contamination are important, and the provision of clean air increases. Although fresh air is usually supplied by general ventilation, the sole use of general ventilation for airborne pollutant control in welding is usually ineffective.

    Coatings on metal make the composition of welding fumes more dangerous 31 October 2017

    Welding fumes contain oxides of the metals in the materials being welded. If not protected by personal protection equipment and proper ventilation measures, a welder and his surrounding are exposed to several health risks by the oxides of the metals.

  • Welding stainless steel produces hexavalent chromium
    Welding stainless steel produces hexavalent chromium 14 July 2017

    Welding of stainless steel is a common process, which has increasing raised concerns for the working environment. Chromium is next to nickel one of the basic alloy element of all groups of stainless steels. During the welding process, chromium is converted to its hexavalent state, Chromium (VI).
