Prior to 1950, sources report that 30 percent of all linemen were electrocuted on the job. As a result, the U.S. Bureau of Labor Statistics has ranked “Lineman” as one of the 10 most dangerous jobs. Since then, insulated equipment such as fiberglass tools and rubber goods, along with well-documented safety techniques and work standards, have improved safety dramatically. Also, mandated periodic safety tests help to keep tools and equipment in working order.
