Limitations of Metal-clad Enclosures to Protect Workers from Electrical Arc-Blasts

Description: A common misconception among electrical workers is that flame resistant clothing is not necessary when working on equipment enclosed inside a metal cabinet. Studies have demonstrated that metal enclosures can only contain electrical arc-blasts of very limited intensity and duration. This presentation will explain how to effectively protect workers from arc-blast hazards.
