The number of electric shock accidents has suddenly been increased in 1990, because of the booming business of the building construction. It was found that many temporal electric wirings and movable electric devices in the field of construction have bee na leading cause of the electric shock accidents. In order to reduce the rate of electric shock accidents the proper authorities will have to establish the safety measures, to educate workers to prevent the accidents and to supervise more carefully.
