[Electrophysiologic criteria for the prevention of electric accidents]

About 0.25 percent of all registered industrial accidents are caused by electric current. One in 20 of these accidents has been fatal. The consequences of electric flow are determined by several factors, above all voltage, time and path of flow, type of current, and resistors within the power circuit. These are attributable to physiological criteria of conduction. Slight electric shock and death by ventricular fibrillation are close to each other by the all-or-nothing law. Conclusions are suggested for practice, and a discussion is proposed with a view to find an adequate definition of the power-related accident.
