The short answer is regulatory limbo. OSHA’s Heat Stress rule, called “Heat Injury and Illness Prevention in Outdoor and Indoor Work Settings,” was part of the Spring 2025 Regulatory Agenda. OSHA also held public hearings in mid-2025 and ended the post-hearing comment period in October of last year. The Agenda did not provide a specific target date for the final rule, thus creating much uncertainty about its future. If it eventually moves forward, it is also likely to contain significant revisions from its current form.

OSHA Mid-Year Rulemaking Update
As we head into the midway point of 2024, we wanted to provide a brief update on significant OSHA rulemaking developments.
Heat Stress: OSHA recently took a critical step in implementing its long-awaited heat stress rule by presenting the draft rule’s initial regulatory framework at a meeting of the Advisory Committee on Construction Safety and Health on April 24, 2024. The Committee unanimously recommended OSHA move forward on the Notice of Proposed Rulemaking. It is more likely now that we may see the rule this summer.

On October 27, 2021, OSHA published an Advance Notice of Proposed Rulemaking (“ANPRM”) to initiate a comment period to gather diverse perspectives and expertise on heat stress issues such as heat stress thresholds, heat acclimatization planning, and exposure monitoring. OSHA has been talking about a need for a heat stress standard, so this development is not surprising. Although OSHA has traditionally addressed heat hazards under the general duty clause, a decision by the Occupational Safety and Health Review Commission on February 28, 2019, in Secretary of Labor v. A.H. Sturgill Roofing, Inc[1]., which reversed an administrative law judge’s order affirming heat-related citations made it more difficult for OSHA to do so. In fact, the Commission in Sturgill specifically questioned the use of the general duty clause calling it more of a “gotcha” and “catch-all” law and opined that once a hazard is identified, such as heat stress, OSHA should engage in rulemaking to allow various stakeholder participation in the process. It seems OSHA has finally taken the Commission up on that offer.
