Railroad Welding and Hexavalent Chromium Exposures

Inhaling welding fumes is the primary source of railroad exposures to hexavalent chromium. Hexavalent chromium can also be found in some of the rust inhibitors which railroad workers use to coat locomotives, railcars, and other machinery. The amount of hexavalent chromium present in welding fumes depends on the amount of chromium in the metal that is being welded. Most steels contain at least some chromium. Stainless steels and mild carbon steels generally contain significant amounts of chromium.

Which Railroad Workers are Exposed to Hexavalent Chromium?

Anyone who is in close proximity to where welding occurs risks exposure to hexavalent chromium. Unfortunately, many railroad employees working in the car department, locomotive shops, and track department encounter welding fumes on a daily basis. Despite the frequency of these exposures, the railroads were historically slow to implement basic safety measures to lessen the danger to their employees.

Is Hexavalent Chromium the Only Carcinogen in Welding Fumes?

No. Welding fumes contain numerous other carcinogens such as arsenic, beryllium, cadmium, and lead.³ Moreover, welding fumes are just one of many toxins that railroad workers are exposed to.
