The dangerous tensions are defined over dangerous rivers.

By definition one assumes rivers are deadly starting from 0,05 A. With a angeommenen of 1000 ohms 50 V would have to then rest against the body. Therefore alternating voltages apply starting from 50 V as deadly. Since DC voltages are harmless, here 120 V are considered as lethal.

The electric current is dangerous for humans and animals. Sweat, saliva, blood and cell liquid are electrolytes, i.e. they lead the electric current.

Nearly all organs function due to electrical impulses, which proceed from the brain. Muscles are steered by weak electrical impulses of approximately 50 mVs. If the human body is energized too much, cramp muscles. Also the contractions of the heart are coordinated by electrical tensions, which are produced by the heart in the sine knot. If the heart is exposed to a high alternating voltage in a certain phase ELECTROCARDIOGRAM, the vulnerablen phase, then it can come to ventricular fibrillations and thus to the heart stop.

Alternating voltage over 50 V are lethal (with animals 25 V). DC voltage over 120 V are lethal (with animals 60 V).

Of live parts on jobs and publicly accessible mechanisms warning of dangerous electrical tension must be warned in Germany by the safety character.
