The Occupational Safety and Health Administration (OSHA) is publishing an Advance Notice of Proposed Rulemaking for Heat Injury and Illness Prevention in Outdoor and Indoor Work Settings on Oct. 27.

Record-breaking heat in the U.S. in 2021 endangered millions of workers exposed to heat illness and injury in both indoor and outdoor work environments. Workers in outdoor and indoor work settings without adequate climate-controlled environments are at risk of hazardous heat exposure, and workers of color are exposed disproportionately to hazardous levels of heat in essential jobs across these work settings.

In concert with a Biden-Harris administration interagency effort and its commitment to workplace safety, climate resilience and environmental justice, OSHA is creating new rules for heat injury and illness. Currently, OSHA does not have a specific standard for hazardous heat conditions and this action begins the process to consider a heat-specific workplace rule.

“As we continue to see temperatures rise and records broken, our changing climate affects millions of America’s workers who are exposed to tough and potentially dangerous heat,” said U.S. Department of Labor Secretary Marty Walsh. “We know a disproportionate number of people of color perform this critical work and they, like all workers, deserve protections. We must act now to address the impacts of extreme heat and to prevent workers from suffering the agony of heat illness or death.”

The Advance Notice of Proposed Rulemaking will initiate a comment period to gather diverse perspectives and expertise on topics, such as heat-stress thresholds, heat-acclimatization planning and exposure monitoring.

“While heat illness is largely preventable and commonly underreported, thousands of workers are sickened each year by workplace heat exposure, and in some cases, heat exposure can be fatal,” said Acting Assistant Secretary of Labor for Occupational Safety and Health Jim Frederick. “The Advance Notice of Proposed Rulemaking for Heat Injury and Illness Prevention in Outdoor and Indoor Work Settings is an important part of our multi-pronged initiative to protect indoor and outdoor workers from hazardous heat.”
