Ladders Maintain ladders in usable condition. Withdraw ladders from service that have developed defects. Do not improvise your own repair of a ladder.
Contact can be lethal.
Use only fiberglass ladders near electrical hazards. Fully extend a step ladder prior to use. Do not use it folded or propped up against a vertical surface. Place the extension ladder base a distance from the vertical wall equal to one-fourth the working length of the ladder. Face the ladder when ascending or descending.
