Compared with other industries, mining is among the most dangerous when it comes to working with electrical power. According to data from the U.S. Bureau of Labor Statistics (as reported by the Centers for Disease Control), the mining industry has an electrical fatality rate approximately eight to 12 times that of other U.S. industries. In addition, mine-related electrical injuries are
