Synopsis
Department of Health and Human Services Centers for Disease Control and Prevention National Institute for Occupational Safety and Health Arc Flash Awareness NIOSH 2007-116d - 2007 An arc flash is the sudden release of electrical energy through the air when a high-voltage gap exists and there is a breakdown between conductors. An arc flash gives off thermal radiation (heat) and bright, intense light that can cause burns. Temperatures have been recorded as high as 35,000 °F. High-voltage arcs can also produce considerable pressure waves by rapidly heating the air and creating a blast. This pressure burst can hit a worker with great force and send molten metal droplets from melted copper and aluminum electrical components great distances at extremely high velocities. This video provides information about arc flashes. The target audience includes employees, electrical workers, trainees, subcontractors, vendors, and visitors to the worksite. The downloadable documents include information and discussion topics for electrical workers.
