SECTION R-315 HANDRAILS


R315.1 Handrails. Handrails having minimum and maximum heights of 30 inches and 38 inches (762 mm and 965 mm), respectively, measured vertically from the nosing of the treads, shall be provided on at least one side of stairways f three or more risers. Sprial stairways shall have the required handrail located on the outside of the radius. All required handrails shall be continuous the full length of the stairs. Ends shall be returned or shall terminate the newel posts or safety termnals. Handrails adjacent to a wall shall have a space not less than 1 1/2 inches (38 mm) between the wall and the handrail.

Exceptions:

  • Handrails shall be permitted to be interrupted by a newel post at a turn.
  • The use of a volute, turnout, or starting easing shall be salloweed over the lowest tread.
R515.2 Handrail grip size. The handgrip portion of handrails shall have a circular cross section of 1 1/4 inches (32 mm) minimum to 2 5/8 inches (67 mm) maximum. Other handrail shapes that provide an equivalent grasping surface are permissible. Edges shall have a minimum radius of 1/8 inch (3.2 mm).

SECTION R316
GUARDS


R316.1 Guards required. Porches, balconies or raised floor surfaces located more than 30 inches (762 mm) above the floor or grade below shall have guards not less than 36 inches (914 mm) in height. Open sides of stairs with a total rise of more than 30 inches(762 mm) above the floor or grade below shall have guards not less than 34 inches (864 mm) in height measured vertically from the nosing of the treads.

R316.2 Guard opening limitations. Required guards on open sides of stairways, raised floor areas, balconies and porches shall have intermediate rails or ornamental closures that do not allow passage of a sphere 4 inches (102 mm) in diameter.

Exception: The triangular openings formed by the riser, tread and bottom rail of a guard at the open side of a stairway are permitted to be of such a size that a sphere 6 inches (152 mm) cannot pass through
