Risks Of Hexavalent Chromium Overexposure

“Hot work,” such as welding and thermal cutting, performed on carbon or stainless steel, exposes workers to toxic and hazardous fumes. Last month, we spoke with Certified Industrial Hygienist (CIH) Mike Harris, PhD of Hamlin & Harris, Inc. about the dangers associated with manganese that welders face. We caught up with Harris again this month to learn about another major threat found in welding fumes: hexavalent chromium (CrVI). Read on to learn about the risks…

The Health Hazards of Manganese on Welders

“If you weld, your chances of being overexposed to manganese are just about 100 percent.” – Mike Harris, PhD, CIH Are you aware of the health hazards of manganese on welders? We spoke with Mike Harris of Hamlin & Harris, Inc. to find out just how toxic welding fumes can be. Harris is a Certified Industrial Hygienist (CIH) who teaches courses on welder health and safety for the American Industrial Hygiene Association (AIHA). According to…

Positioning Of The Source Capture Hood During Welding

For welding, AQE recommends utilizing a source capture hood as the primary means of capturing smoke, fumes and VOC’s. For many manual welding jobs, the welder will be welding on parts that are positioned or clamped on a table. In addition, there may be a custom fixture in use to assure repeatability. For larger weldments, the welder will be welding directly on a part that is “free-standing”. In either scenario, the positioning of the source…

Welding Hazards and Your Workplace

A recent article published by IARC (International Agency for Research on Cancer) estimates that 11 million workers worldwide have a job title of “welder” and an additional 110 million workers probably incur welding related exposures such as fumes, gases, radiation, asbestos, and solvents. The hazards from welding extend beyond the welders. People working with and near welders are also susceptible to the same carcinogens as the welders. It is also possible that the workers near…
