Electrical injury states (Virginia, Florida, Alabama, North Carolina and Kentucky) of the United States. Use of insulated gloves , insulated boots, mats and tools. Protecting electrical circuit with RCD (Residual-current device). Electrical injury Electrical injury is a physiological reaction caused by electric current passing through the (human) body. Electric shock occurs upon contact of a (human) body part with any source of electricity that causes a sufficient magnitude of current to pass through the victim's flesh, viscera or hair. Physical contact with energized wiring or devices is the most common cause of an electric shock. In cases of exposure to high voltages,
Electrical equipment in hazardous areas Electrical equipment in hazardous areas In electrical engineering, hazardous locations (sometimes abbreviated to HazLoc, pronounced "Haz·Lōk") are defined as places where fire or explosion hazards may exist due to flammable gases, flammable liquid–produced vapors, combustible liquid–produced vapors, combustible dusts, or ignitable fibers/flyings present in the air in quantities sufficient to produce explosive or ignitable mixtures. Electrical equipment that must be installed in such classified locations should be specially designed and tested to ensure it does not initiate an explosion, due to arcing contacts or high surface temperature of equipment. The introduction of electrical apparatus for signaling or lighting in coal
