The potential health hazards associated with the installation, maintenance, and operation of high voltage transmission lines were reviewed. Specific hazards considered included exposure to ozone (10028156), audible noise, electric shock, and high intensity electromagnetic fields. Experiments were conducted to simulate the worst possible conditions. Under these conditions the exposure of the workers to ozone was quite substantial. Direct measurement of these exposures should be made on the job. While the exposure to noise levels was lower than minimum levels estimated to cause hearing loss, noise on the line may make it difficult to hear the words of fellow workers which could present a hazardous situation if a spoken warning is not heard. Although no evidence exists to suggest hazards arising from exposure to electromagnetic fields, the tests thus far have considered fields weaker than peak occupational exposures. The authors recommend that actual field measurements be taken. Harmful effects of exposures to electric shock would include respiratory arrest, ventricular fibrillation, and burns.
