Charge to Peer Reviewers:

The goals of this document are to describe the:

  1. critical animal, human, and in vitro studies on occupational exposure to hexavalent chromium;
  2. relevant quantitative risk assessments about occupational exposure to hexavalent chromium;
  3. appropriate methods for sampling and analysis of hexavalent chromium compounds in the workplace;
  4. basis for the NIOSH revised Recommended Exposure Limit for hexavalent chromium compounds;
  5. other NIOSH recommendations for protecting workers from occupational exposure to hexavalent chromium.

The charge to the Peer Reviewers is to objectively review the document to determine whether:

  • the hazard identification is a reasonable reflection of the available scientific studies,
  • the NIOSH recommendations for protecting workers from occupational exposure to hexavalent chromium are appropriate, and
  • NIOSH has a transparent and sound basis for its revised Recommended Exposure Limit for hexavalent chromium compounds.

To facilitate review of this Criteria Document, the questions below should be considered:

  1. Are the critical studies presented clearly and adequately?
  2. Do all of the presented studies use scientifically valid methods and techniques?
  3. Are there additional critical studies relevant to occupational exposure to hexavalent chromium compounds that should be included?
  4. Does NIOSH have a transparent and sound basis for its revised Recommended Exposure Limit for hexavalent chromium compounds?
  5. Is the new NIOSH policy of providing general exposure assessment recommendations instead of a specific Action Level scientifically justified?
  6. Are the NIOSH recommendations for worker protection clear and justified?
  7. Are there additional recommendations for worker protection that should be included?
