Which statement about hexavalent chromium exposure in welding environments is supported by the material?

Which statement about hexavalent chromium exposure in welding environments is supported by the material?

• A. Hexavalent chromium can be found in paints, dyes, acids, and preservatives
• B. Hexavalent chromium is found only in metal coatings
• C. Hexavalent chromium is not hazardous
• D. Hexavalent chromium exposure is limited to outdoor environments

Answer: (A)

Hexavalent chromium exposure comes from a variety of sources beyond just metal coatings. Cr(VI) compounds have historically been used in paints and pigments, dyes, wood preservatives, and certain acids and preservatives, so workers can encounter it even when not dealing with metal finishing. This breadth of sources explains why the statement that hexavalent chromium can be found in paints, dyes, acids, and preservatives is the best match to how Cr(VI) appears in real welding and industrial environments. The other ideas—restricting Cr(VI) to metal coatings, claiming it isn’t hazardous, or saying exposure is only outdoors—do not reflect how Cr(VI) is encountered in practice.
