2006 New York Code - Moving Walkways.

 
    §  27-379  Moving walkways. Pedestrian walkways consisting of conveyor
  belts shall be considered as exit passageways if level, or as  ramps  if
  inclined,  and  shall  be  acceptable  as  exits if they comply with the
  applicable requirements for exit passageways  or  ramps,  and  with  the
  following:
    (a)  Capacity.  The capacity shall be as listed under exit passageways
  or ramps, as the case may be, in table 6-1.
    (b) Acceptable exits. Only walkways moving in the  direction  of  exit
  travel  may  be credited as exits, except that any moving walkway may be
  credited when it is connected to an automatic fire detection system that
  will cause it to stop simultaneously with the detection of fire  on  the
  floor   it   serves.   Such  detection  system  shall  comply  with  the
  construction provisions of subchapter seventeen of this chapter.
    (c)  Design  and  construction.  Walkways  shall   comply   with   the
  requirements of subchapter eighteen of this chapter.
    (d)  Enclosure.  Walkways that do not serve as exits, but are inclined
  so as to require an opening in any floor, shall be enclosed as  required
  for escalators in subdivision (c) of section 27-378 of this article.
