An electrical injury (electric injury) or electrical shock (electric shock) is damage sustained to the skin or internal organs on direct contact with an electric current. [ 2 ] [ 3 ] The injury depends on the density of the current , tissue resistance and duration of contact. [ 4 ]
Three elements are required for an electrocution to occur: (a) a charged electrical source, (b) a current pathway through the victim, (c) a ground. The health hazard of an electric current flowing through the body depends on the amount of current and the length of time for which it flows, not merely on the voltage. However, a high voltage is ...
An electrical burn is a burn that results from electricity passing through the body causing rapid injury. Approximately 1000 deaths per year due to electrical injuries are reported in the United States, with a mortality rate of 3-5%. [1] [2] Electrical burns differ from thermal or chemical burns in that they cause much more subdermal damage. [3]
Possible sources of macroshock include: poorly designed or malfunctioning electrophysiology equipment, lightning, damaged power cords or other electrical hazards around the household, downed power lines, high-voltage electrical equipment such as transformer stations and other industrial electrical equipment, and malfunctioning electrical or electricity-using mechanical equipment capable of ...
Faulty electrical connections and damaged electrical equipment can lead to an electric shock to workers and to others at or near the workplace. [ 35 ] According to the Bureau of Labor Statistics , a total 1,738 accidents occurred due to contact with electric current between 2003 and 2010, and out of that, the highest number of electrical ...
Electrical shocks on humans can lead to permanent disabilities or death. Size, frequency and duration of the electrical current affect the damage. [8] The effects from electric shock can be: stopping the heart beating properly, preventing the person from breathing, causing muscle spasms. The skin features also affect the consequences of ...
Electric shock — Physiological reaction of a biological organism to the passage of electric current through its body. Ferranti effect — A rise in the amplitude of the AC voltage at the receiving end of a transmission line , compared with the sending-end voltage, due to the capacitance between the conductors, when the receiving end is open ...
A flexible electrical cord may be damaged by door or window edges, by staples and fastenings, by equipment rolling over it, or simply by aging. [20] The potential for possible electrocution or electric shock or contact with electrical hazards can result from a number of factors, including the following:
