Electrical hazards exist in almost every workplace in Arizona. However, safety authorities say most electrician accidents occur on construction sites. They say many workers suffer electrical shocks that are never reported, and for that reason, the existing records indicate only serious and fatal electrical injuries.
The hazards include overhead power lines, faulty equipment, lightning, damaged insulation, improper grounding and doing maintenance or repairs without de-energizing the equipment. An electrical shock happens when an electrical current passes through a worker's body, causing him or her to become a part of the electrical circuit. For that to happen, the worker must touch two electrical currents with different voltages, or be in contact with an electric current and a ground without being protected by shoes with rubber soles -- for instance.
