High temperatures, direct sun, limited air circulation, physical exertion, physical illnesses and some medications can lead to heat stress. The human body becomes stressed if it is unable to cool itself and prolonged exposure drains the body of vital fluids. Read more about heat induced illnesses & prevention on the Occupational Safety & Health Association’s (OSHA’s) website. OSHA recommends misting as one way to combat these heat induced illnesses. Watch closely for symptoms of heat exhaustion & heat stroke if you or your employees are exposed to prolonged high temperatures.
