SUPPLEMENTARY INFORMATION: On August 30, 2024, OSHA published in the
Federal Register a Notice of Proposed Rulemaking (NPRM) for Heat Injury
and Illness Prevention in Outdoor and Indoor Work Settings. The
proposed standard would apply to all employers conducting outdoor and
indoor work in all general industry, construction, maritime, and
agriculture sectors where OSHA has jurisdiction. The standard would
clarify employer obligations and the steps necessary to effectively
protect employees from hazardous heat.
OSHA held an informal public hearing on the proposed standard from
June 16 through July 2, 2025. At the close of that hearing, the
presiding administrative law judge set the post-hearing comment period
for 90 days, until September 30, 2025. The purpose of the post-hearing
comment period is to allow individuals and organizations who filed a
timely NOITA at the hearing to file evidence and data relevant to the
proceeding, including written responses to questions asked during
hearing proceedings, as well as final written briefs. On September 9,
2025, counsel for the Coalition for Workplace Safety (CWS) filed a
request for a 90-day extension of the post-hearing comment period.
Document ID OSHA-2021-0009-25568.
Upon consideration of the request, the chief administrative law
judge granted an extension of 30 days of the post-hearing comment
period. Document ID OSHA-2021-0009-25570. See 29 CFR 1911.16(g).
Accordingly, individuals and organizations who filed a timely NOITA may
submit post-hearing comments until October 30, 2025.
