To combat the hazards associated with extreme heat exposure both indoors and outdoors, the White House announced efforts the U.S. Department of Labor is taking to address heat-related illnesses. The department's Occupational Safety and Health Administration (OSHA) is initiating measures to protect workers in hot environments and reduce the dangers of exposure to ambient heat.

OSHA is implementing an enforcement initiative on heat-related hazards, developing a National Emphasis Program on heat inspections, and launching a rulemaking process to develop a workplace heat standard. In addition, the agency is forming a National Advisory Committee on Occupational Safety and Health Heat Injury and Illness Prevention Work Group to provide better understanding of challenges and to identify and share best practices to protect workers.

OSHA Area Directors across the nation will institute the following:

• Prioritize inspections of heat-related complaints, referrals and employer-reported illnesses and initiate an onsite investigation where possible.
• Instruct compliance safety and health officers to conduct an intervention during their job site visits (providing the agency's heat poster/wallet card, discuss the importance of easy access to cool water, cooling areas and acclimatization) or opening an inspection when they observe employees performing strenuous work in hot conditions.
• Expand the scope of other inspections to address heat-related hazards where worksite conditions or other evidence indicates these hazards may be present.

In October 2021, OSHA will issue an Advance Notice of Proposed Rulemaking on heat injury and illness prevention in outdoor and indoor work settings. The advance notice will initiate a comment period allowing OSHA to gather diverse perspectives and technical expertise on topics including heat stress thresholds, heat acclimatization planning, exposure monitoring and strategies to protect workers.
