Handbook for Playground Safety <br />• For toddlers: <br />— The average incline of a slide chute should be no more <br />than 24° (that is, the height to horizontal length ratio <br />shown in Figure 20 does not exceed 0.445). <br />No section of the slide chute should have a slope <br />greater than 30°. <br />— The slide chute should be between 8 and 12 inches wide. <br />• For preschool- and school -age children: <br />— The average incline of a slide chute should be no more <br />than 30° (that is, the height to horizontal length ratio <br />shown in Figure 20 does not exceed 0.577). <br />— No section of the slide chute should have a slope <br />greater than 50°. <br />5.3.6.3.5 Tube slides <br />• Tube slides should meet all the applicable recommenda- <br />tions for other slides (e.g., side height, slope, use zone at <br />exit, etc.). <br />• Means, such as barriers or textured surfaces, should be <br />provided to prevent sliding or climbing on the top <br />(outside) of the tube. <br />• The minimum internal diameter of the tube should be no <br />less than 23 inches. <br />• Tube slides should have transparent tube sections for <br />observation and supervision; otherwise, children using <br />tube slides may not be visible to a supervisor. <br />5.3.6.4 Chute exit region <br />All slides should have an exit region to help children main- <br />tain their balance and facilitate a smooth transition from sit- <br />ting to standing when exiting. The chute exit region should: <br />• Be between 0 and -4° as measured from a plane parallel to <br />the ground. <br />• Have edges that are rounded or curved to prevent lacera- <br />tions or other injuries that could result from impact with a <br />sharp or straight edge. <br />• For toddlers the chute exit region should: <br />— Be between 7 and 10 inches long if any portion of the <br />chute exceeds a 24° slope. <br />Be no more than 6 inches above the protective <br />surfacing. <br />Have a transition from the sliding portion to the exit <br />region with a radius of curvature of at least 18 inches. <br />• For preschool- and school -age the chute exit region <br />should: <br />Be at least 11 inches long. <br />Be no more than 11 inches above the protective <br />surfacing if the slide is no greater than 4 feet high. <br />Be at least 7 inches but not more than 15 inches above <br />the protective surfacing if the slide is over 4 feet high. <br />Height (H) <br />of platform <br />above exit <br />Horizontal distance (D) of exit <br />from beginning of slide chute <br />000000000000y000000001IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII <br />Figure 20.
