Power lines are used to carry electricity. It is very dangerous to touch them. You do not have to touch them for an electrical accident to happen; the electric shock could come about by just getting too close to the line.
When in doubt, you must always assume that a line is an electrical one and, therefore, is energized. Never carry out any of the following activities near a power line:
If you see that some animal or object is touching a power line, you should report the situation to Iberdrola Distribución Eléctrica by calling 900 17 11 71 in order to have technicians remove it. Should a person be touching a power line, you must call the emergencies telephone number 112 first.
