Electrical safety in industrial plants

Abstract

Most electrical engineers and electricians are aware that the principal danger from electricity is that of electrocution, but few really understand just how minute a quantity of electric energy is required for electrocution. Actually, the current drawn by a 7½-watt 120-volt lamp, passed from hand to hand or foot, is enough to cause fatal electrocution. Just as it is curent. and not voltage, that heats a wire, it is current that causes physiological damage. This article gives some indication of what this damage consists of, with specific application to the problems of industrial plants.
