The U.S. Department of Labor's Occupational Safety and Health Administration (OSHA) has opened a comment period for proposed federal regulations aimed at enhancing heat safety for workers. These regulations are particularly significant for farm workers and others who must work in extreme temperatures. The move comes amid growing concerns about the impact of climate change, which has reportedly doubled heat-related deaths. The proposed rules are part of broader efforts to address worker safety and climate change, building on initiatives like the Inflation Reduction Act.
