Heat Stress

Workers in hot environments

 

Heat-induced occupational illnesses, injuries, and reduced productivity can occur with excessive exposure to a hot work environment. Heat-induced disorders include transient heat fatigue, heat rash, fainting, heat cramps, heat exhaustion, and heat stroke. Aside from these disorders, heat poses the threat of injuries because of accidents caused by slippery palms as a result of sweating, fogged up safety glasses, and dizziness. Severe burns can also occur as a direct result of accidental contact with hot surfaces and steam. The links below provide acess to more information on heat-induced occupational illnesses, injuries, and reduced productivity, as well as methods that can be taken to reduce risk.

Esta Pãgina en Espaņol En Español
From iron workers to pastry bakers, Americans work in a wide variety of hot or hot and humid environments. Being uncomfortable is not the major problem with working in high temperatures and humidities. Workers who are suddenly exposed to working in a hot environment face additional and generally avoidable hazards to their safety and health. This publication discusses the safety and health consequences of heat stress.
