Height (H) of platform above exit Horizontal distance (D) of exit from beginning of slide chute Platform Figure 20. Slide Slope 35 Handbook for Public Playground Safety 5.3. . Chute exit region All slides should have an exit region to help children maintain their balance and facilitate a smooth transition from sitting to standing when exiting. The chute exit region should: • Be between 0 and -4° as measured from a plane parallel to the ground. • Have edges that are rounded or curved to prevent lacerations or other injuries that could result from impact with a sharp or straight edge. • For toddlers the chute exit region should: – Be between 7 and 10 inches long if any portion of the chute exceeds a 24° slope. – Be no more than 6 inches above the protective surfacing. – Have a transition from the sliding portion to the exit region with a radius of curvature of at least 18 inches. • For preschool- and school-age the chute exit region should: – Be at least 11 inches long. – Be no more than 11 inches above the protective surfacing if the slide is no greater than 4 feet high. – Be at least 7 inches but not more than 15 inches above the protective surfacing if the slide is over 4 feet high. • For toddlers: – The average incline of a slide chute should be no more than 24° (that is, the height to horizontal length ratio shown in Figure 20 does not exceed 0.445). – No section of the slide chute should have a slope greater than 30°. – The slide chute should be between 8 and 12 inches wide. • For preschool- and school-age children: – The average incline of a slide chute should be no more than 30° (that is, the height to horizontal length ratio shown in Figure 20 does not exceed 0.577). – No section of the slide chute should have a slope greater than 50°. 5.3.6.3.5 Tube slides • Tube slides should meet all the applicable recommendations for other slides (e.g., side height, slope, use zone at exit, etc.). • Means, such as barriers or textured surfaces, should be provided to prevent sliding or climbing on the top (outside) of the tube. • The minimum internal diameter of the tube should be no less than 23 inches. • Supervisors should be aware of children using tube slides since the children are not always visible.
