Hexavalent chromium (Chromium 6) also found in welding fumes

4 Jun 2019 Health risks

What is hexavalent chromium & how to act for best protection.
A recent case (early February 2019) of financial compensation for 800 workers who have been exposed to the hazardous hexavalent chromium in the workshop of the Nederlandse Spoorwegen (NedTrain-department) in Tilburg, the Netherlands, has again put the spotlight on the danger of this substance.

New evidence: welding fumes can cause lung cancer

22 Feb 2019 Health risks

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.

Welding fumes classified as Carcinogenic to humans

19 Feb 2019 Health risks

Welding fumes and UV radiation from welding are now classified as “carcinogenic to humans” by the IARC.

Metal fume fever. What is it and how to prevent it?

29 Oct 2018 Health risks

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

23 Jul 2018 Health risks

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

27 Feb 2018 Health risks

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 Feb 2018 Health risks

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.

Different possibilities to reduce the risks of welding fumes

24 Nov 2017 Health risks

To extract welding fumes and protect the welder, at source ventilation is always the most efficient and safe way. In addition, all kinds of measures can be taken to reduce welding fumes and its risks.

Coatings on metal make the composition of welding fumes more dangerous

31 Oct 2017 Health risks

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

14 Jul 2017 Health risks

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).
