This video addresses a problem of an estimated 5 to 10 arc flash accidents occurring in electrical equipment every day in the United States, in 2007. These events have the potential to cause serious injuries and even death due to burns and other trauma. In the mining industry, non-contact electrical burns due to arc flash events are the largest single category of electrical injuries. To address this problem, NIOSH OMSHR researchers conducted a study of such injuries from an 11-year period, with findings that included the determination of organizational and human behavior components of arc flash incidents. http://www.cdc.gov/niosh/mining/works/coversheet1841.html
