They kind of have to though. While they have what is known in the power industry as a "chicken stick" tool, the risk of arc over is pretty extreme. The boom is fiberglass, but the end needs to be something a little more conductive than cardboard to knock ice off the roof. That requires some heft and that's usually metal.While the workers are safe with the chicken sticks should power somehow come on, the metal on the ends of them would in many cases close the gap between the wire and the ceiling sufficiently to draw some arcs. When I saw this article, emailed a buddy who works for AMTK and he said, "oh yeah, they shut down the tunnel for a little over a half hour to do that and then clear up." |
