Examples of climbers <br />School -age children tend to use climbing and upper body <br />equipment more frequently and more proficiently than <br />preschool children. Young preschool children may have diffi- <br />culty using some climbers because they have not yet devel- <br />oped some of the physical skills necessary for certain climb- <br />ing activities (balance, coordination, and upper body <br />strength) . Older preschool children (i.e., 4- and 5-year-olds) <br />are beginning to use flexible climbers, arch climbers, and <br />upper body devices. However, playgrounds designed for chil- <br />dren under 4 years of age should avoid arch climbers, flexible <br />climbers, horizontal ladders, parallel bars, and other upper <br />body components. <br />5.3.2.1 Design considerations <br />5.3.2.1.1 Layout of climbing components <br />When climbing components are part of a composite struc- <br />ture, their level of challenge and method of use should be <br />compatible with the traffic flow from nearby components. <br />Upper body devices should be placed so that the swinging <br />movement generated by children on this equipment cannot <br />interfere with the movement of children on adjacent struc- <br />tures, particularly children descending on slides. The design <br />of adjacent play structures should not facilitate climbing to <br />the top support bars of upper body equipment. <br />5.3.2.1.2 Fall Height <br />Climbers: <br />• The fall height for climbers is the distance between the <br />highest part of the climbing component and the protec- <br />tive surfacing beneath it. <br />• If the climber is part of a composite structure, the fall <br />height is the distance between the highest part of the <br />climber intended for foot support and the protective <br />surfacing beneath it. <br />— Toddlers: The maximum fall height for free standing <br />and composite climbing structures should be 32 inches. <br />Upper Body Equipment: <br />• The fall height of upper body equipment is the distance <br />between the highest part of the equipment and the pro- <br />tective surface below. <br />5.3.2.1.3 Climbing rungs <br />Some of the access methods discussed in §5.2 are also con- <br />sidered climbing devices; therefore, the recommendations for <br />the size of climbing rungs are similar. <br />24 <br />
