NIOSH guidebook Occupational Exposure to Heat and Hot EnvironmentsReduce employee illness and injury from workplace heat stress

Workers who are exposed to extreme heat or work in hot environments indoors or outdoors, or those engaged in strenuous physical activities may be at risk for heat stress. Exposure to extreme heat can result in occupational illnesses caused by heat stress, including heat stroke, heat exhaustion, heat syncope, heat cramps, heat rashes, or death.

Heat can also increase workers’ risk of injuries, as it may result in sweaty palms, fogged-up safety glasses, dizziness, and may reduce brain function responsible for reasoning ability, creating additional hazards. Those at risk of heat stress include outdoor workers and workers in hot environments, such as fire fighters, bakery workers, farmers, construction workers, miners, boiler room workers, and factory workers.
