Electrocution on farms is often due to overhead power lines. You do not have to touch a power line to be electrocuted with overhead power lines as the power arcs. Harvest time on farms is a particularly risky.
Aerial power lines, defective wiring and extension cords are common causes of electrocution.
If someone is electrocuted, it is vital to disconnect the power supply before you try to help them. After you disconnect the power source, give first aid and seek medical help.
Injuries and death from an electric shock can include burns and disturbances to heart rhythm (heart failure) that could be fatal.
