Response: Manufacturers and importers are required to develop and provide HCS 2012-compliant safety data sheets and labels for hazardous chemicals to downstream users by June 1, 2015, in accordance with 29 CFR 1910.1200(j)(2). OSHA understands the complexity and scale of the changes required of manufacturers, such as those identified by your constituent, during this transition period. However, OSHA continues to believe that the Hazard Communication Standard, as currently designed, is necessary for the long-term safety of downstream consumers and the current compliance deadline is appropriate.

OSHA has reviewed the various options available to the Agency to address the issue raised and can provide relief through enforcement guidance. OSHA is able to use its enforcement discretion when compliance staff considers whether manufacturers and importers have performed their due diligence and made good faith efforts to obtain necessary information to comply with the June 1, 2015 effective date. Our policy allows us to consider barriers to the downstream flow of information that are beyond the manufacturer's or importer's control in deciding whether and how to pursue enforcement actions. Manufacturers and formulators should therefore document all efforts to alternatively obtain the required information, such as attempts to contact their supplier to obtain the proper information; reasonable efforts to find alternate suppliers who could provide timely and accurate classifications; and reasonable efforts to find relevant data themselves.

Response: The OSHA pictograms do not replace the diamond-shaped labels that the DOT requires for the transport of chemicals, including chemical drums, chemical totes, tanks or other containers. Those labels must be on the external part of a shipped container and must meet the DOT requirements set forth in 49 CFR 172, Subpart E. If a label has a DOT transport pictogram, Appendix C.2.3.3 of HCS 2012 states that the HCS pictogram for the same hazard shall not appear. However, DOT does not view the HCS pictogram as a conflict, and for some international trade both pictograms may need to be present on the label. Therefore, the Agency will allow both DOT and HCS pictograms for the same hazard on a label. OSHA worked with DOT to reconcile labeling conflicts, and the two agencies continue to work together.

While the DOT diamond label is required for all hazardous chemicals on the outside shipping containers, the HCS 2012 label must be on the hazardous chemical's immediate container.

Response: During the development of the HCS 2012, OSHA was required to determine if this standard was economically feasible. This is explained in Section VI of the preamble of the 2012 Hazard Communication Federal Register (Volume 77, No. 58, March 26, 2012, pgs. 17605-17683). The Regulatory Flexibility Act, as amended by the Small Business Regulatory Fairness Act (SBREFA), required OSHA to determine if the regulation had a significant impact on a substantial number of small entities. As explained in the preamble, it was determined that the rule would not have a significant impact on small entities.
