Building codes and research findings do not completely agree over how to place handrails so they might serve the above functions. Research done by Maki and Fernie (1988) indicates a handrail height of 36 to 40 inches is most effective in preventing falls when descending stairs.
If balusters are used, there shall be a minimum of one per tread. Handrails shall be a minimum of 1 1/4 inches (3.18 cm) in outside diameter; and (5) Vertical clearance shall be at least 6 feet, 6 inches (1.98 m) above the top step. (c) Maintenance. Spiral stairways shall be maintained in safe condition.f) If the foot of a gangway is more than one foot (0.30 m) away from the edge of the apron, the space between them shall be bridged by a firm walkway equipped with a hand rail with a minimum height of approximately 33 inches (0.84 m) with midrails on both sides.
