What are the causes of Arc Flash?

Arc flash incidents can be triggered by accidental contact between an energized conductor, such as a
bus bar or wire, and another conductor or a surface connected to the earth. Furthermore, equipment
malfunction can also contribute to the occurrence of such incidents.
While many assume that arc flash risks primarily arise when working with high voltage, emerging
evidence suggests that low voltage scenarios may carry greater risk. Research indicates that the severity
of hazards is often higher at low voltage levels than in high voltage situations.
The potential for harm varies depending on multiple factors, including the magnitude of current flowing
through the arc, the duration of the arcing fault, the distances between conductive parts bridged by the
arc, the presence of electrodes, the confinement surrounding the arc, the chemical composition of
conductors and surrounding materials, and the proximity of workers to the arc.
