- Safety and Health Topics
- Hexavalent Chromium
This section highlights OSHA directives (instruction to OSHA staff) and letters of interpretation (official letters of interpretation of the standards) related to hexavalent chromium.
- Hexavalent Chromium National Emphasis Program. CPL 02-02-076, (February 23, 2010).
- Inspection Procedures for the Chromium (VI) Standards. CPL 02-02-074, (January 24, 2008). Includes a summary of the Cr(VI)Standards for general industry, construction, and shipyards, and instructions to OSHA compliance officers for the uniform conduct of inspections and enforcement actions.
- Additional Information
- Inspection Procedures for Construction Sites Using Portland Cement. (April 16, 2007). Instructs OSHA compliance officers not to apply new 29 CFR 1926.1126 for construction site exposures to portland cement. Portland cement is specifically excluded from that standard, even though cement may have trace amounts of chromium (VI). Officers are instructed, instead, to enforce existing standards for PPE, sanitation, air contaminants, hazard communication, and recordkeeping. See OSHA's Concrete and Concrete Products - Manufacturing and Construction Safety and Health Topics Page.
