Proposed rule; request for comments - OSHA is proposing through this notice of proposed rulemaking (NPRM) to modify the Hazard Communication Standard (HCS) to conform to the United Nations' Globally Harmonized System of Classification and Labelling of Chemicals (GHS) Revision 7 (GHS, Rev. 7), to address issues that arose during the implementation of the 2012 update to the HCS, and provide better alignment with other U.S. agencies and international trading partners, without lowering overall protections of the standard. OSHA has preliminarily determined that the proposed revisions to the HCS will reduce costs and burdens while also improving the quality and consistency of information provided to employers and employees regarding chemical hazards and associated protective measures. Consistent with the Executive order entitled 'Improving Regulation and Regulatory Review' (18 January 2011) and section 3(a) of the Regulatory Flexibility Act, which call for assessment and, where appropriate, modification and improvement of existing rules to minimize any significant economic impact upon a substantial number of small entities, OSHA has reviewed the existing HCS. The agency has preliminarily determined that the proposed revisions will enhance the effectiveness of the HCS by ensuring employees are appropriately apprised of the chemical hazards to which they may be exposed, thus reducing the incidence of chemical-related occupational illnesses and injuries. The proposed modifications…

Hazard Communication Standard; Corrections
The Occupational Safety and Health Administration (OSHA) is correcting several inadvertent errors in its Hazard Communication Standard (HCS). Most errors relate to the HCS final rule published in the Federal Register on 20 May 2024 (notified as G/TBT/N/USA/1697/Add.4). On 9 October 2024, the agency issued a corrections notification and technical amendment (notified as G/TBT/N/USA/1697/Add.4/Corr.1) to correct errors in that final rule which the agency believed could lead to confusion during the classification process or errors on labels and Safety Data Sheets (SDSs) if not expeditiously corrected. Following publication of the 9 October 2024 corrections notification and technical amendment, OSHA continued its review of the regulatory text and identified additional minor and typographical errors in the regulatory text and appendices to the HCS. OSHA is issuing this correction document to address these additional minor errors. OSHA is also making one technical amendment to an appendix of the HCS unrelated to the 20 May 2024 final rule. The corrections in this document are effective 8 January 2026. The incorporation by reference of certain material listed in this rule was approved by the Director of the Federal Register as of 19 July 2024. 91 Federal Register (FR) 562, 8 January 2026; Title 29 Code of Federal Regulations (CFR) Part 1910: This and previous actions notified under the symbol G/TBT/N/USA/1697 are identified by Docket Number OSHA-2019-0001.

Hazard Communication Standard
OSHA is correcting several inadvertent errors in its Hazard Communication Standard (HCS) which were published in the Federal Register on 20 May 2024 (notified as G/TBT/N/USA/1697/Add.4). The agency has identified several errors in the regulatory text and appendices to the HCS which pertain to the classification of hazardous chemicals and information presented on labels and Safety Data Sheets (SDSs). The agency believes these errors, although minor and primarily typographical in nature, should be addressed expeditiously to avoid confusion or unnecessary costs in the regulated community due to incorporation of errors on labels and SDSs. OSHA is continuing its review of the regulatory text and will issue another correction document to address additional minor errors at a later date. 9 October 2024 89 Federal Register (FR) 81829, Title 29 Code of Federal Regulations (CFR) Part 1910: This final rule; correction and technical amendment and previous actions notified under the symbol G/TBT/N/USA/1697 are identified by Docket Number OSHA-2019-0001.
