Dear Mr. Kenyon:
Thank you for your letter to the Occupational Safety and Health Administration (OSHA). Your letter was referred to OSHA’s Directorate of Enforcement Program for a response. Your question is in regards to OSHA’s Hazard Communication Standard’s (HCS 2012) June 1, 2016 effective date. This letter constitutes OSHA’s interpretation only of the requirements herein, and may not be applicable to any questions not delineated within your original correspondence. Your paraphrased question and our response follow below.
Question: What are the end-user requirements to have a label and safety data sheet (SDS) for a chemical (5-year shelf life) packaged and shipped prior to June 1 and December 1, 2015, respectively?
Response: End users (i.e., employers) with existing stock or who have received shipped containers of hazardous chemicals with HCS 1994 labels and material safety data sheets (MSDSs) (even after the June 1, 2016 final effective date) are allowed to maintain and use those containers with HCS 1994 labels and MSDSs. The end user must not remove or deface any labels (including HCS 1994 labels) on chemical containers, unless the end user immediately marks the containers with workplace labeling. See 29 CFR § 1910.1200(f)(9). If an end user receives HCS 2012 labels from an upstream supplier for its existing stock, it is advisable to affix the HCS 2012 label over the HCS 1994 label, although it is not required. In addition, paragraph (f)(11) requires employers who become aware of any significant information regarding the hazards of a chemical to revise the labels within six months of becoming aware of the new information. When an end-user receives a compliant HCS 2012 SDS, it must replace the MSDS for the corresponding hazardous chemical. The end-user is also responsible for training its workers regarding the new label elements.
Thank you for your interest in occupational safety and health. We hope you find this information helpful. OSHA’s requirements are set by statute, standards, and regulations. Our letters of interpretation do not create new or additional requirements but rather explain these requirements and how they apply to particular circumstances. This letter constitutes OSHA’s interpretation of the requirements discussed. From time to time, letters are affected when the agency updates a standard, a legal decision impacts a standard, or changes in technology affect the interpretation. To assure that you are using the correct information and guidance, please consult OSHA’s website at http://www.osha.gov. If you have further questions, please feel free to contact the Office of Health Enforcement at (202) 693-2190.
