Electrical burn on hand. 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 ...
A corona discharge occurs at locations where the strength of the electric field (potential gradient) around a conductor exceeds the dielectric strength of the air. It is often seen as a bluish glow in the air adjacent to pointed metal conductors carrying high voltages, and emits light by the same mechanism as a gas discharge lamp ...
Electrical injury; Other names: Electrical shock: Lightning injury caused by a nearby lightning strike. The slight branching redness (sometimes called a Lichtenberg figure) travelling up the leg was caused by the effects of current. Specialty: Emergency medicine: Complications: Burns, rhabdomyolysis, cardiac arrest, bone fractures [1] Frequency
Electrical burns are caused by contact with electricity as it enters and passes through the body. They are often deeper than other burns, affecting lower tissues as electricity penetrates the skin, and the full extent of electrical burns are often obscured. They will also cause extensive destruction of tissue at the entry and exit points.
A burn is an injury to skin, or other tissues, caused by heat, cold, electricity, chemicals, friction, or ionizing radiation (such as sunburn, caused by ultraviolet radiation). [5] [9] Most burns are due to heat from hot liquids (called scalding), solids, or fire. [10] Burns occur mainly in the home or the workplace.
Corona discharge — occurs at sharp points and edges (radius < 1 mm). It is a uniform ionization (glow discharge) visible as a dim stationary blue glow, fading out as it extends from the conductor. Brush discharge — occurs at a curved electrode (radius between 5 and 50 mm) [3] in the vicinity of a flat electrode. It consists of a short ...
Contact injury: injury that occurs when a person is touching an object on the pathway of lightning; Ground current: lightning strikes nearby and the current travels through the ground to the person; Lightning injury may occur by these electrical mechanisms or by secondary blunt trauma as a result of the strike.

Chemical burns may occur through direct contact on body surfaces, including skin and eyes, via inhalation, and/or by ingestion. Substances that diffuse efficiently in human tissue, e.g., hydrofluoric acid , sulfur mustard , and dimethyl sulfate , may not react immediately, but instead produce the burns and inflammation hours after the contact.
