The different parts of the humanbody such as the skin, blood, muscles, other tissues and joints present to the electric current a certain impedance composed of resistive and capacitive components.

When a current exceeding 30 mA passes near the heart of a human body, the person concerned is in serious danger if the current is not interrupted in a very short time. Electrical fires are caused by overloads, short circuits and earth leakage currents, but also by electric arcs in cables and connections.
This page was last modified on 23 Aprilat Contact with parts in fault conditions Indirect contact. Protection against electric shocks and electrical fires. Residential premises and other special locations. The values of body impedance depend on a number of factors and, in particular, on current path, on touch voltage, duration of current flow, frequency, degree of moisture of the skin, surface area of contact, pressure exerted and temperature.
The following test report forms are related: Protection measures are described in Protection against electrical fire risks. An electric shock is the pathophysiological effect of an electric current through the human body.

Basic protection Fault protection. Its passage affects essentially the muscular, circulatory and respiratory functions and sometimes results in serious burns. The degree eic danger for the victim is a function of the magnitude of the current, the parts of the body through which the current passes, and the duration of current flow.

The necessary criterion is the admissible limit of touch voltage i. The relationship between current and voltage is not linear because the impedance 11 the human body varies with the touch voltage, and data on this relationship is therefore required.
