摘要： The aspects herein relate to the field of fall prevention systems, and more specifically to fall arrest systems for storage bins and more particularly to grain bins or silos. In one aspect, a fall prevention system for a ladder may have an anchor plate coupled to a roof. In another aspect, the fall prevention system for the ladder may have an anchor bar coupled to at least a portion of the ladder. A rope is coupled at one end to the anchor plate or bar and at the other end to at least one rung of the ladder using a fastener. A rope grab is slidably coupled to the rope between the anchor plate or bar and the fastener.
