A ladder includes a pair of opposing side rails and at least one attachment device configured to be attached to a fall arresting device. The opposing side rails have a plurality of steps disposed therebetween along substantially an entire length of the opposing side rails. The attachment device is configured to be attached to a fall arresting device and is substantially centrally disposed between the pair of opposing side rails. The attachment device is a plate, substantially parallel to a plane defined by the opposing side rails, that extends from one of the side rails to the other side rail. The ladder includes a pair of curved members respectively extending from the pair of opposing side rails at an upper distal end of the ladder. One of the attachment devices is positioned substantially centrally along a longitudinal axis of the ladder, and another of the attachment devices is positioned substantially proximate to the upper distal end of the ladder.
