Consideration of Electrical Fatal Accident by Electric Shock and Preventive Measures Caused in 2018

Abstract

When a human body of workforce touches charged objects of live line, an electric current by the electric shock flows in the human body and the electric shock accident occurs. The human body feels a numbness when the electric current of more than 1 mA flows through it, and the workforce is dead by occurrence of ventricular fibrillation when the current of about 50 mA flows through it. When we consider the electric shock accident on the earth, there is a possibility of occurrence of many electrical fatal accidents. We need to provide a basis of the prevention of electric shock accident for utilizing the prevention of the accident of not only Japan, but also U.S.A etc. Though the studies on the prevention of electric shock accident is performed on domestic and overseas, the research study on recent electric shock accident is not so many. This study reports the study results capable of eliminating the electrical fatal accident in future when we consider the causes and preventive measures from case studies of electrical fatal accident by the electric shock in 2018. The fruits will expect to useful for the prevention of electrical fatal accident by the electric shock.
