Arc flash injury is due to extreme heat generated when an electrical device is subjected to an electrical fault, such as short circuits or ground faults. The National Electrical Code (NEC), Article 110.16 requires switchboards, panelboards, motor control centers, industrial control panels, etc. to be filed marked to warn persons of potential Arc flash hazards.
Standards such as NFPA70E and IEEE 1584 provide means to calculate the Arc flash energy at a particular distance from the arc source. Depending on the distance of the person from the source of Arc flash, the standards indicate the type of personal protective equipment (PPE) to prevent serious injury. Arc flash hazard analysis calculates the incident energy and the PPE requirements. Arc flash hazard labels of the type shown to the right provide the information needed by facility owners, operators, maintenance personnel, and others to be informed of the hazard potential and the PPE necessary to prevent serious injuries.
