Grounding intentionally creates a low-resistance path that connects to the earth. This will prevent the buildup of voltages that could cause an electrical accident that could result from a worker being in the ground path. A properly designed grounding system creates a low-resistance path away from workers Electric current can cause injury in four ways: Cardiac arrest due to the electrical effect on the heart Muscle, nerve, and tissue destruction from a current passing through the body Thermal burns from contact with the electrical sourc Electrical accidents are common, if not unavoidable, in the manufacturing environment. They occur for a number of reasons, whether it concerns the management, equipment, or employees. There's often no one person to blame; as the old saying goes, accidents just happen Electrical injuries, a relatively common form of mechanical trauma, can occur as a result of lightning, low-voltage or high-voltage injury, and are often associated with a high morbidity and mortality. Almost all electrical injuries are accidental and often, preventable An electric shock is caused when a person is exposed to and/or comes into contact with a source of electricity, directly or indirectly sending an electrical current through a portion of the person's body. Causes of electric shock can include: Contact with a powerline or electrical arc flash Accidental contact with exposed electrical source

Almost all American workers are exposed to electrical energy at sometime during their work day, and the same electrical hazards can affect workers in different industries. Based on the analysis of these cases, NIOSH identified five case scenarios that describe the incidents resulting in 244 fatalities: (1) direct worker contact with an energized powerline (28%); (2) direct worker contact with. Burn injuries - Electricity can cause either electrical burns from direct contact with current or thermal burns from arc flashes and blasts. Arc flashes happen when powerful, high-amperage currents arc or travel through the air. When an arc flash happens, the temperature can reach as high as 36,000 degrees Fahrenheit Electrical injuries can range from small skin burns to life threatening internal organ damage. The most extreme form of electric shock, such as caused by a lightning strike, often results in instant death by electrocution. There is a lack of evidence regarding the management of patients after electrical accidents, which can cause concern for.
