It is aluminum, so it is conductive. All of the ladders we used on the fire trucks were also aluminum. I notice the electricians all use fiberglass ladders. But they are working around live wires also. Our 6 foot -8 foot step ladders are fiberglass/aluminum, the lttle step ladders are aluminum. Our extnesion ladders are aluminum.
I am not sure how important the conductivity issue is. Working at night, in poor visiblity, I am sure all of have walked into wires. we have also laddered a building and hit wires. Not all of the fan wiring is water tight, and we wet those down, usually while standing in a puddle. I know all of us have tipped fans and found the bad wires when they get wet and spark. When in the fire service, I hit meter boxes with 1.5 and 2.5 hoses.
I used to really worry about water and electricity, but after 25 + years, I do not anymore. But I still respect and know that electricity can knock you on your ass and can kill you dead.
