Abstract: TWO COUNTY WORKERS WERE REPLACING A ROAD SIGN LOCATED IN A DITCH ALONG THE SOUTH SIDE OF A COUNTY ROAD. THEY WERE USING A GS INDUSTRIES, INC., CRANE (GS 72 MODEL NO. 261, SERIAL NO. 722611185) MOUNTED ON A 1985 GMC TRUCK. THEY DUG A HOLE FOR THE 16-FOOT-LONG, 4-INCH-BY-6-INCH REPLACEMENT SIGNPOST. THEN THEY HOOKED A CHAIN TO THE POST TO PLACE IT IN THE HOLE. ONE OF THE EMPLOYEES (EMPLOYEE #1) WAS AT THE CRANE'S CONTROLS; THE OTHER EMPLOYEE WAS STANDING NEXT TO THE TRUCK AT ITS REAR WHEELS. AS THE OPERATOR SWUNG THE BOOM FROM THE ROAD TOWARD THE DITCH, THE BOOM CONTACTED A 7200-VOLT OVERHEAD POWER LINE THAT WAS DIRECTLY ABOVE THE POST HOLE. THE EMPLOYEES, WHO WERE BOTH TOUCHING THE TRUCK, WERE ELECTROCUTED.
