  2. Electrical injury - Wikipedia

    en.wikipedia.org/wiki/Electrical_injury

    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 ]

  3. Electrical burn - Wikipedia

    en.wikipedia.org/wiki/Electrical_burn

    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]

  4. High voltage - Wikipedia

    en.wikipedia.org/wiki/High_voltage

    The definition of extra-high voltage (EHV) again depends on context. In electric power transmission engineering, EHV is classified as voltages in the range of 345,000– 765,000 V. [6] In electronics systems, a power supply that provides greater than 275,000 volts is called an EHV Power Supply, and is often

  5. Electrocution - Wikipedia

    en.wikipedia.org/wiki/Electrocution

    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 ...

  6. Lightning injury - Wikipedia

    en.wikipedia.org/wiki/Lightning_injury

    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]

  7. Developmental bioelectricity - Wikipedia

    en.wikipedia.org/wiki/Developmental_bioelectricity

    Developmental bioelectricity is a sub-discipline of biology, related to, but distinct from, neurophysiology and bioelectromagnetics.Developmental bioelectricity refers to the endogenous ion fluxes, transmembrane and transepithelial voltage gradients, and electric currents and fields produced and sustained in living cells and tissues.

  8. Physical hazard - Wikipedia

    en.wikipedia.org/wiki/Physical_hazard

    Electrical burns cause tissue damage and need immediate medical attention. Electric shocks can result in injuries such as muscle spasms, palpitations, nausea, vomiting, collapse, and unconsciousness. [35] Faulty electrical connections and damaged electrical equipment can lead to an electric shock to workers and to others at or near the ...

  9. Laboratory safety - Wikipedia

    en.wikipedia.org/wiki/Laboratory_safety

    Hazardous chemicals present physical and/or health threats to workers in clinical, industrial, and academic laboratories. Laboratory chemicals include cancer-causing agents (carcinogens), toxins (e.g., those affecting the liver, kidney, and nervous system), irritants, corrosives, sensitizers, as well as agents that act on the blood system or damage the lungs, skin, eyes, or mucous membranes.
