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 ...
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
The effects of burns vary depending on the depth and size. Superficial or first-degree burns only affect the epidermis, causing pain for a short period of time. Superficial partial-thickness burns cause weeping blisters and require dressing. Deep partial-thickness burns are dry and less painful due to the burning away of the skin and require ...
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 ...
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.
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.

Liquid dielectrics are self-healing; when an electric breakdown occurs, the discharge channel does not leave a permanent conductive trace in the fluid. The electrical properties tend to be strongly influenced by dissolved gases (e.g. oxygen or carbon dioxide), dust, fibers, and especially ionic impurities and moisture. Electrical discharge may ...
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] Complications can include electrolyte, heart, lung, kidney, and neurological ...
