Care iuid be given to understand the exception for the in- erence of handrail mounts on lhe gripping surfaces smailer profiles in effectively evaluating their spability. For a discussion of this, see Section The exception allows for an alternative, Type II handrail, within residential units and lheir associated structures. A handrail on common stairways within an aPartment buiiding or on the steps to the front door of a townhouse could not use this exception. This is con- sistent with the IRC. �y,3.1 7'ype I. Hm�drnils with a circular cross section shall ve an outside diameter of at ]cast 1'/4 inches (32 mm) and not �alcr than 2 inches (51 mm). If thc hnndrail is not circular, it ill have a perimeter dimcnsion of at Icast 4 inchcs (102 mm) i not greater than 6'/, inche� (IGO mm) with a maximum �ss-section dimension o! 2'/a inches (57 mm), Edgcs sliali �c a minimum radius of 0.01 inch (0.25 mm). Handrails have tradilionally been regulated as either circular or noncircular rails. The noncircular rails have previously been limited to a maximum perimeter di- mension of 6'/, inches (160 mm), with other limitations addressing rninimum perimeter and maximum cross- sectional dimensions. These handrails shapes are now referred to 3s Type I handrails. This class of handrails includes circular cross sec- tions with an outside diameter of at least 1'/, inches �1EANS OF EGRESS (32 mm) but not greater lhan 2 inches (51 mm). It limits the perimeter of the cross section such that ihe grip- ping surface incorporales ihe bottom of the rail. A handrail with either a very narrow or a large cross sec- tion is not graspable in a power grip by all able-bodied users and cerlainly not by those with fiand-strength or Oexibility deficiencies. Noncircular Type I cross sec- tions can be approved by way of the alternative noncircular criteria in this section, but the bottom of the rail must be considered part of the suitable gripping surface. Edges must be slightly rounded and not sharp.
