The maximum rise for any run is 30'. The maximum run 30'. The minimum inside clear width of a ramp should be 36'.
Landings must be provided at the top and bottom of each run. The landing should be at least as wide as the ramp, and a minimum of 60' in length. Argumentation and critical decision making pdf. Handrails must be provided on both sides of the ramp, between 30' and 38' above the ramp surface. Suggestions:. All wood should be treated.
