| 説明 | Bradley Nickel, an engineer from Altalink, discusses the Canada utility’s fall protection program and studies on using modified stepbolts on steel towers as a possible way to help the utility comply. Modified step bolts that allow linemen to clip into the step bolt could be one way for a utility to comply with the new regulations. (Photo by Lisa Meiman) |
