| 4.8.2 | Running Slope: | Is the ramp slope 1:12 or less? | |||
| Maximum Rise: | Is the rise for any run a maximum of 30 inches? | ||||
| 4.8.6 | Cross Slope: | Is the cross slope of the ramp surface no greater than 1:50? | |||
| 4.8.6; 4.5 | Surface: | Is the ramp surface stable, firm and slip-resistant? | |||
| Grates: | Is the smaller dimension of grate openings no more than 1/2 inch, and are long dimensions of rectangular gaps placed perpendicular to the usual direction of travel? | ||||
| 4.8.3 | Clear Width: | Is the clear width (between handrails) of the ramp at least 36 inches? 4.8.4LandingsIs there a level landing at the top and bottom of each ramp and each ramp run? | |||
| Size: | Is each landing at least as wide as the ramp and at least 60 inches long? | ||||
| Where the ramp changes direction, is there a landing of at least 60 by 60 inches? | |||||
| Landings with Doors: | If a doorway is located on a landing, does the area in front of the door comply with the maneuvering space requirements for doors? (Use Form 11: Doors and Gates) | ||||
| 4.8.7 | Edge Protection: | If a ramp or landing has a drop off, does it have a minimum 2 inch curb, a wall, railings, or projecting surfaces which prevent people from falling off? | |||
| 4.8.8 | Drainage: | Are outside ramps and their approaches designed so that water will not accumulate on walking surfaces? | |||
| 4.8.5 | Handrails: | If the ramp rises more than 6 inches or is longer than 72 inches, does it have a handrail on each side? (Handrails are not required on curb ramps or adjacent to seating in assembly areas.) | |||
| On dogleg or switchback ramps, is the inside handrail continuous? | |||||
| Gripping Surface: | Are the gripping surfaces continuous? | ||||
| Mounting: | Are handrails fixed so that they do not rotate within their fittings? | ||||
| Height: | Is the top of the handrail between 34 and 38 inches above the ramp surface? | ||||
| Handrail Extension: | At ends of handrails, are there at least 12 inches of handrail, parallel to the floor or ground surface, extending beyond the top and bottom of the ramp segment? | ||||
| Ends of Handrails: | Are the ends of handrails rounded or returned smoothly to the floor, wall, or post? | ||||
| 4.8.5 4.26.2 |
Diameter: Is the diameter of the handrail between 1-1/4 and 1-1/2 inches? OR Does the shape provide an equivalent gripping surface? Note: Standard pipe sizes designated by the industry as 1-1/4 to 1-1/2 inches are acceptable for purposes of this section. | ||||
| 4.8.5 4.26.2 |
Clearance: | Is the clear space between handrails and walls exactly 1-1/2 inches? | |||
| 4.8.5 4.26.2 |
Clearance in Recess: | If a handrail is located in a recess, is the recess no more than 3 inches deep extending at least 18 inches above the top of the rail? | |||
| 4.8.5; 4.26.3 | Structural Strength: | Do the handrails meet the structural strength requirements for bending stress and shear stress? (See 4.26.3) | |||
| 4.8.5 4.26.3 |
Do the fasteners meet the structural strength requirements for shear force and tensile force? (See 4.26.3) | ||||
| 4.8.5 4.26.4 |
Hazards: | Are handrail edges free of sharp or abrasive elements and do they have edges with a minimum radius of 1/8 inch? |
