2006 New York Code - General Provisions For Suspended Scaffolds.

 
    § 27-1045 General provisions for suspended scaffolds. (a) Installation
  and  use.  Suspended  scaffolds  shall be erected and operated in such a
  manner that suspension elements are vertical and in a plane parallel  to
  the  wall  at  all  times. The installation or change of position of any
  suspended scaffold  shall  be  performed  under  the  supervision  of  a
  designated  superintendent or foreman who shall enforce such measures as
  may be required for the safe execution of such operation.
    (b) Tests and inspections required. All suspended scaffolds  shall  be
  inspected  daily  by  the  user before use. A record of such inspections
  shall be kept and maintained at the  field  office  of  the  user.  Upon
  delivery  of  the  scaffold  equipment to the site, the supplier of such
  equipment shall  furnish  a  certificate  from  an  independent  testing
  laboratory  or  a  licensed  professional engineer stating that physical
  tests of a prototype of the  equipment  were  conducted  and  that  such
  equipment  is  capable  of  withstanding at least four times the maximum
  allowable live loads. Such certificates  shall  be  kept  at  the  field
  office  of  the  user  and  shall  be  available  for  inspection  by  a
  representative of the department of buildings.  This  section,  however,
  shall  not  be  construed  to  reduce  the  factors  of safety specified
  elsewhere in this code for various appurtenances to this  equipment.  In
  addition,  tests  prescribed  in  section  27-998  of  article  three of
  subchapter eighteen shall be performed with the full rated live load  on
  the  scaffold  at the test intervals specified therein and at such other
  intervals as the commissioner may require.
    (c) Tie-ins. Scaffolds shall be tied into the building  or  structure,
  and  means  therefor shall be provided. Window cleaners' anchors, window
  frames, millions, or similar  elements  shall  not  be  used  as  tie-in
  anchors or brace-back points.
    (d) Wire rope. Wire rope used for support of suspended scaffolds shall
  be  capable  of  supporting  six  times  the actual applied load without
  failure, but shall not be  less  than  five-sixteenths  of  an  inch  in
  diameter  for use with light duty platforms or one-half inch in diameter
  for use with medium or heavy duty platforms. Wire rope shall  be  rigged
  to  blocks  of  proper  size  or  to  other  approved devices. For other
  provisions concerning wire rope, see section 27-1055 of article  ten  of
  this subchapter.
