Natural boundaries or fences help keep children from wandering off and unwanted visitors from entering. Equipment should be designed for a range of ages and abilities, and it should be installed with safety in mind. For instance, equipment that moves requires lots of surrounding space. Children should never be able to ram into one piece of equipment from another or fall into a barrier. In a carefully constructed environment, children are able to roam between activities without getting into playground traffic jams.
Equipment is sturdy and engineered for safety.
The placement, size, height and complexity of equipment must be tailored to the children who use it. For example, climbing equipment should not be taller than the children who climb. Slides with large decks and hand rails at the top. Swings placed 2 to 3 feet apart to reduce chances of mid-air collisions. Landing surfaces are resilient.
