The outdoor play area should be enclosed with a fence or natural barriers. Fences and barriers should not prevent the supervision of children by caregivers/teachers. If a fence is used, it should be in good condition and conform to applicable local building codes in height and construction. These areas should have at least two exits, with at least one being remote from the buildings.
Gates should be equipped with self-closing and positive self-latching closure mechanisms that are high enough or of a type such that children cannot open it. The openings in the fence and gates should be no larger than 3 ½ inches. The fence and gates should be constructed to discourage climbing. Outside play areas should be free from unsecured bodies of water. If present, all water hazards should be inaccessible to unsupervised children and enclosed with a fence that is 4 to 6 feet high or higher and comes within 3 ½ inches of the ground.
