Investigation of Worker Vapor Exposure and Occupational Medicine Program Allegations at the Hanford Site

This report provides the results of an independent investigation of selected aspects of worker safety and health systems at the U.S. Department of Energy's (DOE) Hanford Site.  The investigation was conducted from February though April 2004 at the direction of the Secretary of Energy by the Office of Independent Oversight and Performance Assurance (OA) within Secretary of Energy’s Office of Security and Safety Performance Assurance.  The Secretary of Energy directed OA to evaluate recent allegations of deficient safety and medical practices, and to assess past practices and current operations to determine whether additional actions are needed to ensure a safe work environment at the Hanford Site.
