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 ]
Contact injury occurs when the person is touching the object that is hit. [1] Direct strikes make up about 5% of injuries. [1] The mechanism of the injuries may include electrical injury, burns from heat, and mechanical trauma. [1] Diagnosis is typically based on history of the injury and examination. [1]
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]
Electrical injuries in the home are often minor, while high tension power cables cause serious electrical injuries in the workplace. Lightning strikes can also cause severe electrical injuries. Fatal electrical injuries are often caused by tetanic spasm inducing respiratory arrest or interference with the heart causing cardiac arrest. [17]
Most (69%) burn injuries occur at home or at work (9%), [15] and most are accidental, with 2% due to assault by another, and 1–2% resulting from a suicide attempt. [25] These sources can cause inhalation injury to the airway and/or lungs, occurring in about 6%. [4] Burn injuries occur more commonly among the poor. [25]

A hydrofluoric acid burn is a chemical burn from hydrofluoric acid. [1] Where it contacts the skin it results in significant pain, swelling, redness, and skin breakdown. [1] [2] If the fumes are breathed in swelling of the upper airway and bleeding may occur. [2]
A man who was present at Nagasaki on August 9, 1945, during the dropping of the 20 kiloton Fat Man bomb, this photo displays that 1st and 2nd degree burn injuries he experienced on his unclothed skin, the shoulder and arm, while the thin vest garment of clothing that he was wearing at the time of the explosion completely protected his stomach and lower chest from experiencing similar burns.
