Dear Ms. Blakeslee:
Thank you for your October 24, 2014, letter to the Occupational Safety and Health Administration (OSHA). Your letter was referred to OSHA's Directorate of Enforcement Programs for an interpretation of OSHA's Hazard Communication standard (HCS 2012), 29 CFR 1910.1200. This letter constitutes OSHA's interpretation only of the requirements discussed and may not be applicable to issues not delineated within your original correspondence. Your paraphrased questions and our responses are below.
Scenario: Your company has a chemical that is packaged in pre-printed bags, which are made to stock and then shipped around the world. In order to reduce relabeling and repackaging, you would like the chemical label to include the chemical hazard classifications for the United States (U.S.), European Union (E.U.), and China in clearly marked separate boxes.
Question 1: Is it acceptable to have other countries' hazard classifications in addition to the U.S. HCS 2012 classification, on a chemical product label?
Response: The HCS 2012 requires chemical manufacturers, importers, or distributors to ensure that each container of hazardous chemicals leaving the workplace is labeled, tagged or marked with the following information: product identifier; signal word; hazard statement(s); precautionary statement(s); and pictogram(s); and name, address and telephone number of the chemical manufacturer, importer, or other responsible party. 29 CFR 1910.1200(f)(1). The HCS 2012 does not prohibit a manufacturer or importer from adding supplemental information to a label, as long as it does not lead to unnecessarily wide variation or undermine the required label information. Section C.3.1 of Appendix C to HCS 2012 explains that supplementary information may only be added to a label if it provides further detail and does not contradict or cast doubt on the validity of the required information. Therefore, if the other countries have hazard classification information that contradicts or casts doubt on the HCS 2012 information, it is not permitted to be on the label. You may wish to review OSHA's January 31, 2013, letter of interpretation (enclosed) to Ms. Erin McVeigh on this subject.
Question 2: A metal alloy is not hazardous in its shipped form, but may release a hazardous chemical when processed downstream. In classifying a metal alloy, must the classifier evaluate the hazards related to processing?
Response: Yes. A manufacturer or importer must consider the hazards of a chemical during normal conditions of use or in a foreseeable emergency. 29 CFR 1910.1200(b)(2). The hazards related to normal processing (e.g. welding, grinding) must be considered in conducting the hazard classification. You may wish to review two past letters of interpretation on this subject: OSHA's March 11, 1986, letter (enclosed) to The Honorable John H. Chafee, and the November 16, 1994, letter (enclosed) to Ms. Sheila Loftus.
Thank you for your interest in occupational safety and health. We hope you find this information helpful. OSHA requirements are set by statute, standards, and regulations. Our interpretation letters explain these requirements and how they apply to particular circumstances, but they cannot create additional employer obligations.
