OSHA is issuing a Notice of Proposed Rulemaking (NPRM) for Heat Injury and Illness Prevention in Outdoor and Indoor Work Settings. This is a significant step toward a federal heat standard to protect workers. The proposed standard would apply to all employers conducting outdoor and indoor work in all general industry, construction, maritime, and agriculture sectors where OSHA has jurisdiction. The standard would require employers to create a plan to evaluate and control heat hazards in their workplace. It would clarify employer obligations and the steps necessary to effectively protect employees from hazardous heat. The ultimate goal is to prevent and reduce the number of occupational injuries, illnesses, and fatalities caused by exposure to hazardous heat.
