3.	A curb, rail, wall, or barrier shall be provided to serve as edge protection. Curb shall be minimum 4 inches (102 mm) in height. A barrier shall be constructed so as to prevent the passage of a 4 inches (102 mm) diameter sphere above ramp grade level.
4.	On circular cross sections, the gripping surface shall have a diameter of between 1-1/2 inches (38 mm) and 2 inches (51 mm).
5.	A clearance of a minimum 1-1/2 inches (38 mm) shall exist between the wall or post surface and the handrail.
6.	At the top and bottoms of handrail sections that stop at a landing, the handrail shall extend 12 inches (305 mm) horizontally beyond the top riser and 12 inches (305 mm) horizontally beyond the bottom tread.
7.	Ramps with a drop off of 30 inches (762 mm) or more to grade shall require guards.
8.	Handrail shall be continuous, without interruption by newel posts or other obstructions.
9.	Handrails shall return to a wall, guard or walking surface.
D.	Structural Performance: Provide handrails and railings capable of withstanding the following structural loads without exceeding allowable design working stress of materials for handrails, railings, anchors, and connections:

Concentrated horizontal load of 200 lbf (0.89 kN) applied to 1 square foot (0.09 m2) at any point in system, including panels, intermediate rails, balusters, or other elements composing infill area. Loads need not be assumed to act concurrently with loads on top rails in determining stress on guard. 
6.	Glass: Fully tempered glass in glass-supported handrails and railings requires a design with a safety factor of 3 applied to the applicable modulus of rupture listed in "Mechanical Properties" in AAMA Aluminum Curtain Wall Series No. 12, "Structural Properties of Glass". 
E.	Thermal Movement: Provide exterior railings that allow for thermal movement resulting from the following maximum change (range) in ambient and surface temperatures by preventing buckling, opening of joints, overstressing of components, failure of connections, and other detrimental effects.
