The ends of any handrail should be rounded or returned smoothly to the floor, wall, or post. Inner handrails on a switchback or turned ramp must always be continuous. In situations where a handrail is not continuous, handrails must extend at least another 12” (30.5 cm) parallel to the flat surface of the ramp landing. The top grippable surface of any ramp handrail must be set at a height between 34”-38” (86.4-96.5 cm) above the ramp surface and a minimum clear width of 36” (91.4 cm) must be provided between handrails. Handrails along both sides of a ramp are required on any ramp system with a rise greater than 6” (15.2 cm) or a horizontal run greater than 72” (182.9 cm). Dimensions will vary based on the desired slope and height needed. The Ramp (Handrails - Utility) has an overall combined height of 4’ (122 cm), total length of 18.7’ (5.7 m), and width of 44” (111.7 cm). For edge protection, utility handrails must include either curbs or barriers at a minimum of 4” (10.2 cm) high along the ramp edge, or an integrated parallel bar at the bottom of the handrail that would restrict the passage of a 4” (10.2 cm) diameter sphere. As free-standing elements, utliity handrails must double as both an assistive handrail and a guardrail that prevents users from accessing the edge of the ramp. Utility ramp handrails are common all-in-one safety components used along any accessible ramp that typically provide user assistance and protection from falling off a ramp. Landings with minimum lengths of 60” (152.4 cm) and widths consistent to the width of the ramp must be provided at the top and bottom of any straight run portions of the turned ramp. Dimensions will vary based on the desired slope and height needed.The landings of turning ramps must have minimum widths and lengths of 60” (152.4 cm) in both directions at the moment that the turn occurs. The Ramp (Turning) has a height of 24” (61 cm), total run length of 36’ (11 m), and overall width of 17’ (5.18 m). However, the sudden change in direction can be challenging for some users, so these ramps should be designed with caution and with accessibility in mind. The ramp may turn either to the left or to the right, depending on the layout and location of the building or structure. This design is typically used in architectural or engineering projects where there is limited space for a ramp and a straight incline is not possible. The size of these landings provides adequate mobility for a wheelchair user to comfortably rotate according to the change in direction. Turned ramps are accessible ramps designed with a 90° change of direction along the accessible route.
