· An arc flash is hotter and brighter than the surface of the sun and louder than a jet, propelling metal shrapnel at more than 1000 km per hour. Causes of arc flash. Arc flash events most frequently occur when circumstances provide the electric current with a way to complete the circuit that differs from the intended path.
This paper presents results from several elements of a recent NIOSH study of arc flash hazards in mining, and provides information and recommendations that can help reduce these injuries. Characteristics of past arc flash injuries in mining are first outlined, such as the electrical components and work activities involved (based on MSHA data).
