Hazard Communication Standard

ACTION: Final rule; correction and technical amendment.

SUMMARY: OSHA is correcting several inadvertent errors in its Hazard Communication Standard (HCS) which were published in the Federal Register on May 20, 2024. 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.

DATES: October 9, 2024.
