  1. Hexavalent Chromium Bryan Seal, CIH, CSP

  2. What is it? • Hexavalent chromium (Cr(VI)) is a toxic form of the element chromium. Hexavalent chromium is rarely found in nature and is generally man-made. • There has been a general decline in the use of chromates in favor of less toxic inorganic and organic pigments where possible.

  3. Health Effects • Lung Cancer • Irritation or damage to nasal passage and respiratory tract • Irritation or damage to the eyes and skin

  4. Industries • Industries • Aerospace • Automotive • Steel Mills/Foundries • Chemical and Dye Producers • Shipyards • Construction

  5. Who’s at risk? • Tasks • Electroplating & Aluminum Etching • Welding • Painting • Sanding, Grinding, Cutting • Salvage operations • Woodworking

  6. How workers can help? • Identify • Reduce exposure • Wear PPE • Hygiene

  7. What Is OSHA Doing? • Standards • Final Rule – Federal Register, Vol. 71, No. 39, February 28, 2006 • Outreach (Guidance Documents) • Small Entity Compliance Guide for the Hexavalent Chromium Standards (OSHA 3320-10N-2006) • Hexavalent Chromium (OSHA 3373-10-2009)

  8. What is OSHA Doing? • National Emphasis Program • National Emphasis Program – Hexavalent Chromium (CPL 02-02-076, 2/23/2010) • Regional Emphasis Program Involving Exposure to Hexavalent Chromium (VI) (2012-02 CPL 04, October 2012) • Compliance Directive • Inspection Procedures for the Chromium (VI) Standards (CPL 02-02-074, 1/24/2008)

  9. Letters of Interpretation (LOIs) • 11/14/2006 1910.1026(d)(3) Use of "objective data" to accurately characterize employee exposures to hexavalent chromium during welding operations. • 01/25/2007 1910.1026(h)(1) Wearing short-sleeved shirts while performing a thermal spray operation with exposure to hexavalent chromium fumes. • 05/31/2007 1910.1026; 1026(a)(4); 1026(b); 1026(c); 1026(f)(1); 1026(j); 1026(j)(3)(i) Use of feasible engineering/work practice controls for exposure to Cr(VI) for welding in confined spaces; housekeeping and disposal of large/bulky waste materials.

  10. LOIs 2008/2009 • 03/27/2008 1910.1026 Clarification of employer's obligation to include social security numbers on employee exposure records. • 06/29/2009 1910.1026 OSHA has no authority to ban use of hexavalent chromium.

  11. LOIs 2010/2011 • 09/30/2010 1910.1026; 1026(d)(2); 1026(j) Clarification of monitoring and sampling requirements for hexavalent chromium. • 02/23/2011 1910.1026; 1026(i); 1026(j) Applicability of the hexavalent chromium standard to welders.
