• Surfaces to be stable, firm, and slip resistant and prevent the accumulation of water on walking surfaces. <br /> • Maximum slope 1:12,where the maximum rise for any run is 30 inches, cross slope of 1:48 or less. <br /> • Minimum 44"width measured between handrails. <br /> HANDRAILS <br /> • Provide 34"-38" high handrails at ramp runs greater than 6 inches. <br /> • Handrails to extend at least 12 inches beyond the top and bottom of any ramp run. <br /> • Handrails to be graspable circular shape between 1 1/4 and 2 inches,typical. Other shapes per IBC 1012.3. <br /> • Gripping surface of handrail to be continuous without interruption by support or other obstructions. <br /> RAMP AND LANDING EDGE PROTECTION <br /> • A curb or barrier is required that prevents passage of a 4-inch sphere below the height of 4 inches for ramps <br /> without railings. When used, railings are required to have one of the following features: <br /> o An intermediate rail mounted 17-19 inches above the ramp or landing surface; <br /> o The surface of the ramp or landing extends 12 inches beyond the inside face of the r ailing. <br /> o Edge protection not required where the ramp rise is no more than 6 inches adjacent to grade, and ramp <br /> meets curb ramp requirements, subject to field inspection. <br /> 12M0 12min <br /> 305 305 <br /> adjoining surface <br /> maximum slope __:20 1 1 ...,_ 12_ ,�_%—curb ramp maximum <br /> \\ C_.�--_ slope <br /> I <br /> (a)Extended Surface (b)Curb or Barrier Fig.4062 <br /> Counter Slope of Surfaces Adjacent to Curb Ramps <br /> Fig.406.9 <br /> GUARDS Ramp Edge Protection ME <br /> • Provide 42" high guards for portions of landings or ramp that are 36 min(915) <br /> more than 30 inches above adjacent grade.
