The second ladder also has two rails interconnected by a plurality of steps and a second set of grooves, interconnected to the first set of grooves, that receive the gate/barrier device so the first ladder and the second ladder can be used and inhibits a person from entering the area between the first ladder and the second ladder through the second ladder's steps.
