OSHA issues further HazCom corrections

On January 8, OSHA issued further technical corrections to its Hazard Communication final rule, which was originally published on May 20, 2024. An initial set of corrections was published October 9, 2024, and OSHA continued to review 29 CFR 1910.1200 and its appendices for errors. The agency said these corrections should reduce confusion during the classification process and prevent errors on labels and safety data sheets.

In the regulatory text at paragraph (c), ‘‘chemicals under pressure’’ was added to the definition of ‘‘physical hazard” and the definition of “liquid” now includes the PSI conversion (14.69 PSI) with the first reference to the value 101.3 kPa.

Numerous images and typographical and formatting errors were corrected in Appendices A, B, C, D, and F to 1910.1200. For a detailed list, see the table in the January 8 Federal Register.

OSHA intends to update related FAQs, guidance documents, and other supporting materials on its Hazard Communication topic page.

As a reminder, the first HazCom compliance date for the revised 2024 final rule is January 19, 2026. See our related article: First HazCom compliance date just around the corner
