On June 11, the U.S. Department of Labor’s Occupational Safety and Health Administration sent its Heat Illness Prevention in Outdoor and Indoor Work Settings proposed rule to the Office of Information and Regulatory Affairs at the Office of Management and Budget for review. The text of the proposal is currently not available to the public. After OIRA completes its review of the rule, the rule will be published in the Federal Register. ABC will be meeting with the OIRA on the proposed rule.

ABC strongly supports worker safety and protection from heat injury and illness while maintaining flexibility for the fluid nature of the construction environment. Any regulatory approach must be simple and should integrate the key concepts of “water, rest and shade.” Employers play a key role in providing education and awareness regarding heat protection, and ABC will continue to support members in ensuring preparedness for heat-related issues through a wide range of resources.


On Oct. 27, 2021, OSHA issued an Advance Notice of Proposed Rulemaking on Heat Injury and Illness Prevention in Outdoor and Indoor Work Settings, which requested information on how to implement regulations to prevent workers from hazardous heat. ABC, as a steering committee member of the Construction Industry Safety Coalition, submitted comments in response to the ANPRM on Jan. 26, 2022.

On April 12, 2022, OSHA announced a National Emphasis Program on Outdoor and Indoor Heat-Related Hazards, which sets out a targeted enforcement effort and reiterates OSHA’s compliance assistance and outreach efforts.

On July 27, 2023, OSHA issued a heat hazard alert to remind employers of their obligation to protect workers against heat illness or injury in outdoor and indoor workplaces. The department also announced that OSHA will intensify its enforcement where workers are exposed to heat hazards, with increased inspections in high-risk industries like construction and agriculture. These actions will fully implement the agency’s National Emphasis Program on heat, announced in April 2022, to focus enforcement efforts in geographic areas and industries with the most vulnerable workers.

In September, OSHA held six Small Business Advocacy Review panel (also known as a SBREFA panel) meetings to gather input on a possible Heat Injury and Illness Prevention in Outdoor and Indoor Work Settings rule. OSHA also issued new resources to protect workers from the effects of heat.

In December 2023, ABC submitted comments as a steering committee member of the Construction Industry Safety Coalition and the Coalition for Workplace Safety in response to OSHA’s potential standard for Heat Injury and Illness Prevention in Outdoor and Indoor Work Settings following its review of the Small Business Advocacy Review Panel materials and the  SBAR Panel’s final report. In September, the SBAR Panel hosted six video conferences to gather input from small entity representatives. An ABC member participated as a SER during one of the video conferences. The panel’s final report was issued on Nov. 3.
