Occupational Safety and Health
Administration (OSHA) Regulation of
Employee Exposure to Heat
July 13, 2021
Employees who work outdoors, including those in industries such as construction and agriculture, may be
exposed to extreme heat conditions. Similarly, certain indoor work situations-such as bakeries,
warehouses, and steel mills-may also expose employees to unsafe heat levels. The lead federal agency
that regulates worker safety and health, the Occupational Safety and Health Administration (OSHA), does
not have any standards that specifically address outdoor or indoor heat exposure.
Heat-Related Illnesses
The National Institute for Occupational Safety and Health (NIOSH) has identified several illnesses that
are related to heat exposure, including heat stroke, which can result in permanent disability or death.
Other heat-related illnesses include heat exhaustion, rhabdomyolysis, heat syncope, heat cramps, and heat
rash. Research published in 2020 by the Centers for Disease Control and Prevention estimates that
between 2004 and 2018 there were an average of 702 annual deaths in the United States due to heat
exposure, with an average of 415 deaths in which heat exposure was the underlying cause and 287 deaths
in which heat exposure was a contributing cause. (This includes employment-related and non-
employment-related deaths.) In 2019, the Bureau of Labor Statistics' Census of Fatal Occupational
Injuries reported 43 employment-related deaths due to environmental heat exposure and an average of 38
annual environmental heat exposure employment-related deaths between 2011 and 2019. Since 1972,
NIOSHhas recommended that OSHA promulgate aheat exposure standard. While Section 22 of the
Occupational Safety and Health Act (OSH Act, 29 U. S. C. §671) authorizes NIOSH to develop
recommended occupational safety and health standards, OSHAis not required by law to promulgate
standards based on these recommendations.
OSHA and Heat Exposure
OSHA does not currently have any specific heat exposure standards. Apotential standard on Heat Illness
Prevention in Outdoor and Indoor Work Settings is listed as being in the prerule stage on the
