Influence of electricity on our organism. Действие электрического тока на организм человека The main danger of electricity is a lack of special sense organs for detection of electric current on distance. The electric current has no smell, taste and colour . It is impossible to feel it without special devices, whether it is energized or not. So people often do not realize available danger and do not accept necessary protective measures. Опасность электрического тока состоит в том, что у человека нет специальных органов чувств для обнаружения на расстоянии электрического тока. Электрический ток не имеет запаха, вкуса и цвета. Невозможно без специальных приборов почувствовать, находится ли данная часть электроустановки под напряжением или нет. Это приводит к тому, что люди часто не осознают реально имеющейся опасности и не принимают необходимых защитных мер.
