![]() Streets and sidewalks, but they are not discussed in this guide. Rights-of-way will further address curb ramps located along public New guidelines the Board is developing for public Requirements for curb ramps apply to ramps that cut through curbs or areīuilt up to them. Landings are permitted slopes not steeper than Landings subject to wet conditions must be designed to prevent theĪccumulation of water. sides of ramp landings with vertical drop-offs not exceeding ½” within 10″ of the minimum landing area.ramp landings serving an adjoining run or stairway.ramps no higher than 6″ that have side flares.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 handrails can be installed after construction, as needed (ramps must be sized so that the minimum clear width is maintained) (§405.8).the clear width can be reduced below 36″ by work area equipment where it is essential to the work being performed (§405.5) and.Ramps on these circulation paths must comply except that: Requirements for minimum exit widths greater than 36″.Ĭommon use circulation paths must be accessible in work areas 1,000 sq. Of egress may further be determined by applicable life safety codes and The width of ramps that are part of a means Ramp runs must have a clear width of 36″ minimum (measured between Specifying a running slope of 7.5% maximum and a cross slope of 1.5% maximum for exterior ramps will accommodate most irregularities or variances due to construction methods or materials according to a study sponsored by the Board ("Dimensional Tolerances in Construction and for Surface Accessibility" by David Kent Ballast.) Recommendation: Providing the least possible slope below the 1:12 (8.33%) maximum offers better usability for a wider range of users. Variations in slope, such as grade breaks within runs, can disrupt The running slope (1:12 maximum) and cross slope (1:48 maximum) are permitted. To be uniform along a run, although slight variations may occur withĬertain materials such as concrete. It also canīe expressed as a percentage, pitch, or in degrees. Slope represents the proportion of vertical rise to horizontal lengthĪnd is specified in the Standards as a ratio (e.g., 1:12). Portions ofĪccessible routes with running slopes steeper than 5% also must be Elevators and, under certain specifiedĬonditions, platform lifts, can be used as an alternative. Ramps and curb ramps are required along accessible routes to spanĬhanges in level greater than ½”. These annotations are prefaced with begin and end image notes.
