I would prefer fiberglass for the stepladder in particular, since
she mentions changing light bulbs- electrical safety


For indoor use, why should an aluminum ladder increase the risk?
The LADDER isn't grounded, and the chances are it's got rubber
feet anyway. so either you're touching a voltage source
and a path to ground at the same time, or you're not.
