ARC-FLASH HAZARD. A dangerous condition associated with the release of energy caused by an electric arc. Source: The U.S. Department Of Energy
An electrical arc is a current, electric in origin, that is deliberately or inadvertently releasing itself throughout an area in between 2 electrodes using a vapor, gas, or air and also using up a fairly reduced voltage completely in between the conductors. The heat, as well as light, generated by this arc, can be extreme that can be utilized for certain benign purposes, such as arc welding or illuminating spotlights. Unintended arcs can have disastrous repercussions, such as fires, shock and burn injuries when truck grounding, as well as workplace property damages.
An arc flash can be seen from a long distance.
