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] Very small currents may be imperceptible or only produce a light ...
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 ...
An injury is any physiological damage to living tissue [ 1 ] caused by immediate physical stress. Injuries to humans can occur intentionally or unintentionally and may be caused by blunt trauma, penetrating trauma, burning, toxic exposure, asphyxiation, or overexertion.
Microwave burns are burn injuries caused by thermal effects of microwave radiation absorbed in a living organism.. In comparison with radiation burns caused by ionizing radiation, where the dominant mechanism of tissue damage is internal cell damage caused by free radicals, the type of burn caused by microwave radiation is by heat—health effects colloquially associated with the term ...
The presence of multiple bolts shows this is a time-exposure photograph. A lightning strike or lightning bolt is a lightning event in which the electric discharge takes place between the atmosphere and the ground. Most originate in a cumulonimbus cloud and terminate on the ground, called cloud-to-ground (CG) lightning.
An electric arc between two nails. An arc flash is the light and heat produced as part of an arc fault (sometimes referred to as an electrical flashover), a type of electrical explosion or discharge that results from a connection through air to ground or another voltage phase in an electrical system. Arc flash is distinctly different from the ...
Photokeratitis or ultraviolet keratitis is a painful eye condition caused by exposure of insufficiently protected eyes to the ultraviolet (UV) rays from either natural (e.g. intense direct or reflected sunlight) or artificial (e.g. the electric arc during welding) sources. Photokeratitis is akin to a sunburn of the cornea and conjunctiva.
