S. 4427 — Heat Workforce Standards Act of 2026

This section states congressional findings that the proposed Occupational Safety and Health Administration standard titled “Heat Injury and Illness Prevention in Outdoor and Indoor Work Settings” (89 Fed. Reg. 70698) is overly prescriptive and burdensome, that its high-heat triggers, rest-break protocols, acclimatization requirements, and detailed written plans render it unworkable, and that applying uniform prescriptive rules across all industries and geographies will cause confusion and undermine worker safety.

This section prohibits the Secretary of Labor from finalizing, implementing, or enforcing 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.
