Background: Workers who are exposed to extreme heat or work in hot environments may be at risk of heat stress. Exposure to extreme heat can result in occupational illnesses and injuries. Heat stress can result in heat-related illnesses such as heat stroke, heat exhaustion, heat cramps, or heat rashes. Heat can also increase the risk of injuries in workers as it may result in sweaty palms, fogged-up safety glasses, and dizziness. Burns may also occur as a result of accidental contact with hot surfaces or steam. Workers at risk of heat stress include outdoor workers and workers in hot environments such as firefighters, bakery workers, farmers, construction workers, miners, boiler room workers, factory workers, and others.

In 1986, NIOSH published a Criteria Document on hot environments [DHHS (NIOSH) Publication No. 86-113]​niosh/​docs/​86-113/​86-113.pdf which identified many of the effects of heat, provided information on appropriate measuring techniques, and made recommendations for occupational standards, prevention and control. In recent years, including during the oil spill response of 2010, questions were raised regarding whether this document needed to be updated with additional research and findings. Recent literature was reviewed to determine areas that needed updating and revision.
