Regarding the characteristics of fatal electric shock accident during the past 10 years, fatalities occurred more frequently in July & August, and AM 10-12 PM & 14-16. Also, the electric shock accident is occurred more frequently in the age group from 30 to 40. Especially, the fatal electric shock accident in construction industry covered more than half of total industry. Therefore, it is strongly requested for the protection technology of an electric shock from the low voltage electric path, grounding method and workers. The aim of this study is to propose the policy about the equipment performance standards and/or worker's safety standards to revise the standards for preventing electric shock accidents on safety workings.

A children's electric shock accidents have broken out because children can easily insert sharp things in 220V receptacle holes. As the test result of pushing force, children's pushing force was about 2-4kg and the pushing force of sharp things was less than 2kg. Therefore, it is reason for electric shock that children's pushing force is large than pushing force of sharp things. We have measured insulation resistance for the receptacles of five companies during 50 weeks in humid condition. As these results, Insulation resistance for the receptacles of J. Co. had rapidly decreased with lapse of time. As the result for investigating the surface of receptacle by SEM and EDX, Al, Fe and Br, which weren't discovered at original form, were produced. Therefore, the receptacles of J. Co. should be the improved in the quality of insulating material because insulation resistance can be decreased in humid environment

As the domestic communication industry has been made rapid progresses, the construction of base stations are also expanded yearly from more than 86,000 ones in the year 2005 to over 300,000 ones in 2013. While the new construction and rebuilt works have been rapidly increased, there has been not tried about the analysis as well as the control of hazards for the construction works. This study is conducted to do not only the focus interview for 27 expert groups who are engaged in the construction works and safety, but also the questionnaires for AHP analysis which is suggested by the Korea Occupational Safety and Health Agency for 92 persons who are engaged in the construction works in order to analyze the hazards of construction works for base stations. The high ranked risk works which are acquired from the two methods are fall under installation of antennae, struck by the hand tools and construction materials under installation of antennae, fall during going up and down the steel tower and telegraph poles and the fall by electric shock during the underground cable works. The control for the above hazards are the installation of fall protection equipments, the installation of safety nets for falling objects and the installation of protection equipment of electric shock.

물놀이 입욕시설 내에서 입욕자는 물의 영향으로 인하여 인체의 피부저항이 다른 어느 장소보다도 현저히 낮은 상태에 있게 된다. 따라서 조명기구 등에 누전이 발생할 경우 미약한 전압에서도 치명적인 감전재해의 우려가 있다. 본 연구는 물놀이 입욕시설 내에서의 조명기구에 의한 감전사고를 방지하기 위하여 국내 외 관련규정을 비교 분석하였으며 또한, 국내 시설실태를 파악하였다. 그 결과 국내의 규정은 외국기준에 비해 적용범위가 불명확하고 환경조건의 구별이 불투명하고 사용전압이 높은 것으로 나타났다. 따라서 국내의 규정도 조명시설의 설치높이를 상향조정하고 조명기기의 외함에는 방수등급의 표기, 선간전압으로의 사용전압을 제한하는 등의 개정이 필요한 것으로 나타났다.
