![]() While the tables represent only a small fraction of the total number of companies in their respective industries, the results can provide insight into where workplace Cr(VI) exposure is occurring in the United States. The industry profile tables in this website are based on Cr(VI) air samples taken during OSHA inspections from 2006 to 2009. This data provides a snapshot of industry sectors and business subcategories where levels of airborne Cr(VI) have been found. This database does not include worksite inspection sample results from many of the 26 States that operated OSHA-approved State Plans or OSHA consultation visits. OSHA provides a publicly available Chemical Exposure Health Database which includes industrial hygiene sample results from OSHA inspections. Industrial processes that involve chromium can result in worker exposure to toxic hexavalent chromium. Where is exposure to hexavalent chromium occurring? Not only does it impart a shiny appearance, but it also protects the underlying metal from rust and corrosion. Use of pigments, spray paints and coatings Chromium in its hexavalent form has been used in industry for decades for metal plating to produce shiny, chrome- plated metal.Welding and other types of "hot work" on stainless steel and other metals that contain chromium.Workplace exposures occur mainly in the following areas: Many workers in a variety of occupations are potentially exposed to Cr(VI) in the United States. The Cr(VI) compound chromic acid is used to electroplate chromium onto metal parts to provide a decorative or protective coating. It also may be used as an anticorrosive agent added to paints, primers, and other surface coatings. Cr(VI) compounds may be used as pigments in dyes, paints, inks, and plastics. Details of all Authorisations can be found on the European Chemical Agency’s (ECHA) Authorisation Applications website. A major source of worker exposure to Cr(VI) occurs during "hot work" such as welding on stainless steel and other alloy steels containing chromium metal. Authorisation applications were submitted and have been approved for the continued use of substances containing hexavalent chromium for aerospace and defence applications. Chromium metal is added to alloy steel to increase hardenability and corrosion resistance. In addition, it targets the respiratory system, kidneys, liver, skin and eyes. It is usually produced by an industrial process. Hexavalent chromium is one of the valence states (+6) of the element chromium.
