Employees who work outdoors face potential dangers associated with heat exposure and stress, says the Occupational Safety and Health Administration.

“Exposure to heat can cause heat cramps and rashes. The most serious heat-related disorders are heat stroke and heat exhaustion. Symptoms include confusion; irrational behavior; loss of consciousness; hot, dry skin; and abnormally high body temperature. Drinking cool water, reducing physical exertion, wearing appropriate clothing and regular rest periods in a cool recovery area can lessen the effects of working in summer heat,” OSHA advises.

The agency has issued a fact sheet explaining heat stress and how it can be prevented. Another fact sheet provides recommendations on how to protect employees from exposure to ultraviolet radiation (UV) and offers information on insect-caused illnesses such as West Nile Virus.
