Electric shock is a major hazard. The severity of the shock will depend on the level of the current and the length of time it is in contact with the body. At very low levels of current the effect may be only an unpleasant tingling sensation, but this may be enough to cause a man to lose his balance and fall. Higher levels of shock can cause fibrillation of the heart which is almost always fatal.
Electric shock can also cause burning of the skin at the point of contact.
