sb4427/introduced-in-senate.txt119 S4427 IS: Heat Workforce Standards Act of 2026U.S. Senate2026-04-29text/xmlENPursuant to Title 17 Section 105 of the United States Code, this file is not subject to copyright protection and is in the public domain.II 119th CONGRESS 2d Session S. 4427 IN THE SENATE OF THE UNITED STATES April 29, 2026 Mr. Cassidy (for himself, Mr. Risch , Mr. Tuberville , Mr. Crapo , Mr. Budd , Mr. Daines , Mr. Sheehy , Mr. Cornyn , and Mr. Tillis ) introduced the following bill; which was read twice and referred to the Committee on Health, Education, Labor, and Pensions A BILLTo prohibit the Secretary of Labor from finalizing, implementing, or enforcing a proposed standard with respect to heat injury and illness prevention, and for other purposes.1.Short titleThis Act may be cited as the Heat Workforce Standards Act of 2026 .2.FindingsCongress finds that—(1)the proposed standard titled Heat Injury and Illness Prevention in Outdoor and Indoor Work Settings published by the Occupational Safety and Health Administration in the Federal Register on August 30, 2024 (89 Fed. Reg. 70698) is overly prescriptive, burdensome to businesses, and confusing for workers;(2)utilizing prescriptive requirements on employers to effectuate the aims of this proposed standard, including high-heat triggers, stringent protocols around rest breaks, strict acclimatization protocols, and highly detailed written safety plans, make the proposed standard unworkable; and(3)creating a proposed standard to regulate indoor heat and outdoor heat with prescriptive and specific requirements, which covers all industries and geographies without regard for unique considerations, will cause confusion and undermine worker safety.3.Prohibition against finalizing, implementing, or enforcing a proposed standard with respect to heat injury and illness preventionThe Secretary of Labor may not finalize, implement, or enforce the proposed standard titled Heat Injury and Illness Prevention in Outdoor and Indoor Work Settings published by the Occupational Safety and Health Administration in the Federal Register on August 30, 2024 (89 Fed. Reg. 70698), or any substantially similar standard.
