Run and landing surfaces that extend at least 12″ beyond the inside face of handrails will provide adequate edge protection by preventing wheelchair casters and crutch tips from slipping off the edge. Non-Circular Cross Section and Clearance (§505.5, §505.7) Circular Cross Section and Clearance (§505.5, §505.7) The gripping surface andĪdjacent surfaces must be free of abrasive or sharp elements. Handrails can have circular or non-circularĬross-sections, but must have rounded edges. Surface requirements and clearances facilitate a power grip along the The Standards do not require lower handrails serving children exceptĪt ramps serving play areas, but include a recommended height (28″ maximum)Īnd separation (9″ minimum) from the required handrail to minimizeĮntrapment hazards. Handrails are required on both sides of ramps with a rise greater thanĦ″. Required door maneuvering clearances can overlap ramp landings (it isĪdvisable to locate the swing of doors outside ramp landings for greater Intermediate Landings Where Ramps Change Direction Handrails are continuous at the inside turn of dogleg or switchback In the same direction of the run, but they can turn or wrap where Handrail extensions required at the top and bottom of ramp runs must be Obstruct or overlap the minimum 60″ by 60″ clearance. Handrails, edge protection, vertical posts and other elements cannot Intermediate landings between runs must be at least 60″ wide clear andĦ0″ long clear where ramps change direction (any change from linear). Landings mustīe designed to prevent the accumulation of water. In level greater than 1:48 are not permitted at landings. Level landings are required at the top and bottom of each run. That must be exerted to negotiate multiple runs. Landings offer resting points, they do not reduce the amount of effort Strenuous for people using manual wheelchairs. The height of runs is limited (30″ maximum), but there is no limit on the
