This bill would prohibit the Secretary of Labor from finalizing, implementing, or enforcing the Occupational Safety and Health Administration’s (OSHA) proposed rule on “Heat Injury and Illness Prevention in Outdoor and Indoor Work Settings.” This would block the Department of Labor from requiring employers to adopt federal heat safety measures such as heat plans, training, water, rest breaks, or cooling steps for workers in high-heat environments. The bill seeks to prevent the establishment of new nationwide mandates for protecting workers from heat-related health risks, instead leaving such decisions to employers or state governments rather than setting federal requirements.
