�������� PUBLI� WO/�/CS' <br /> RAMPS (cont.) <br /> • 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 '/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 /> ' � <br /> 12 min j 72 min � � <br /> 305 / 305 � <br /> _ _r _ pdjeining surface-. <br /> i � I marimum slope �. __ _. 2� 12 ..._..__ _ _._..� curh ramp maximum <br /> � � I' - -— -- slope <br /> � � � -- <br /> � ---- ---- - <br /> i i <br /> (a)Extended SuHace (b)Curb or 6arrter Fig.4062 <br /> Counter Slope of SuAaces AdJacent to Curb Ramps <br /> Fig.405.9 <br /> GUARDS Ramp Edge Prolectlon i <br /> • Provide 42" high guards for portions of landings or ramp that are 36 min(915) <br /> more than 30 inches above adjacent grade. sect;or,aos�� ! <br /> • Guard openings should not allow a 4 inch sphere to pass, except •as�°in Pubiic � �� � <br /> as noted in IBC section 1013.3.
