Current through Register Vol. 46, No. 28, July 10, 2024
(a) Design.
(1) Every multiple-point suspension scaffold,
					 including all its supports and fastenings, shall be designed by a professional
					 engineer licensed to practice in the State of New York. A copy of the typical
					 drawings and all specifications, signed by such professional engineer, shall be
					 kept on the job site available for examination by the commissioner.
(2) Every multiple-point suspension scaffold
					 shall be designed and constructed with a factor of safety in compliance with
					 the Labor Law and this Part (rule), except that wire ropes supporting the
					 platform shall be at least five-sixteenths inch in diameter and capable of
					 supporting at least six times the load intended to be imposed on such
					 scaffold.
(3) Every multiple-point
					 suspension scaffold shall be provided with an approved hoisting
					 machine.
(4) Outrigger beams and
					 platform bearers of multiple-point suspension scaffolds shall be constructed of
					 structural grade metal. A detailed inspection of each such beam or bearer shall
					 be made prior to installation and use and such inspection shall be repeated at
					 intervals of not more than 30 days during scaffold use. Such inspections shall
					 be made by competent designated persons who shall complete and sign a written
					 record of the results of each such inspection. Such written record shall be
					 kept at the job site available for examination by the commissioner.
(5) Platform supports of multiple-point
					 suspension scaffolds shall be designed to provide sufficient headroom for easy
					 passage throughout the lengths of such scaffolds.
(6) Effective means shall be provided to
					 prevent rope supports from slipping off the ends of the outrigger
					 beams.

Current through Register Vol. 46, No. 28, July 10, 2024
(a) Use of
					 needle beam scaffolds. Needle beam scaffolds shall be used only for the support
					 of persons performing riveting, plastering, painting and other similar work.
					 Needle beam scaffolds shall not be used for the storage of materials.
(b) Scaffold platform supports. Wood needle
					 beams shall not be less than four inches by six inches in size and shall be so
					 placed that the greater dimension is vertical. They shall be of one length and
					 shall not be spliced. Such beams shall be provided with intermediate supports
					 or hangers in such manner that any span shall not exceed 10 feet. Where metal
					 beams are used for needle beam scaffold platform supports, such beams shall be
					 at least equal in strength to the four inch by six inch wood beams.
(c) Rope. Rope used for the support of needle
					 beams shall be equivalent in strength to one- inch diameter first grade manila
					 rope. Such rope shall be attached to the needle beams with "square hitches"
					 which shall be so tied on rectangular beams as to prevent such beams from
					 rolling or otherwise becoming displaced. Mechanical stops such as cleats or
					 pins shall be used to prevent the ropes from slipping off the ends of the
					 beams.
(d) Scaffold platform.
(1) The platform planks for needle beam
					 scaffolds shall not be less than two inches in thickness full size. Platform
					 planks shall extend not less than 12 inches beyond any support nor more than 18
					 inches beyond any end support.
(2)
					 The dimension of any needle beam scaffold platform in a direction parallel to
					 the needle beams shall be not less than three feet nor more than six
					 feet.
(3) When needle beam
					 scaffolds are used with one beam higher than the other or where the platform
					 planks are not level, the platform shall be secured against slipping.

					 tipping.
(c) Construction of
					 horses.
(1) The minimum sizes of members for
					 horse scaffolds used for light duty shall be two inches by four inches for the
					 backs or bearers and one inch by four inches for the legs and horizontal
					 braces. The span of such backs or bearers shall not exceed four feet.
(2) The minimum sizes of members of horse
					 scaffolds used for medium duty shall be one and one-quarter inches by nine
					 inches for the backs or bearers and one and one-quarter inches by four and
					 one-quarter inches for the legs and horizontal braces. The span of such backs
					 or bearers shall not exceed six feet.
(3) The minimum sizes of members of horse
					 scaffolds used for heavy duty shall be three inches by four inches for the
					 backs or bearers and one and one-quarter inches by four and one-quarter inches
					 for the legs and horizontal braces. The span of such backs or bearers shall not
					 exceed six feet.
(4) The backs or
					 bearers of horse scaffolds shall in every case rest on gusset braces which are
					 at least one inch thick.
(5) Every
					 horse scaffold shall be provided with sufficient diagonal and horizontal
					 bracing to assure rigidity.
(6) In
					 lieu of wood, the legs of such horses may be constructed of metal which is in
					 every case equivalent in strength to the wood herein required.
(7) Horse scaffold legs may be lengthened by
					 means of splicing on extension pieces having the same cross-sectional areas as
					 the scaffold legs, provided such extension pieces lap the full lenghts of the
					 scaffold legs and are securely attached to the legs by through bolts.

Current through Register Vol. 46, No. 28, July 10, 2024
(a) Construction of brackets. Each supporting
					 bracket of a carpenters' portable bracket scaffold shall consist of a
					 triangular portable frame constructed of wood not less than two inches by three
					 inches in cross-section or shall be constructed of metal of equivalent
					 strength. The members of such brackets shall be properly fitted and securely
					 joined.
(b) Bracket installation.
					 Each such bracket shall be attached to the wall of a building or other
					 structure by means of a bolt not less than five-eighths inch in diameter. Such
					 bolt shall extend through such wall and shall be secured to develop the
					 required strength. The brackets shall be spaced not to exceed eight feet,
					 center to center. Where the use of five-eighths inch diameter bolts for such
					 installations is impractical, such brackets shall be secured by whaler cleats
					 or metal ties equivalent in strength to five-eighths inch diameter
					 bolts.
(c) Loading. No more than
					 two persons shall occupy any given 16 feet of a carpenters' portable bracket
					 scaffold at any one time. The total weight of supplies, tools, materials or
					 equipment placed on any such scaffold in addition to the occupants shall not
					 exceed 100 pounds.
(d) Safety
					 railing. Where the working platform of any carpenters' portable bracket
					 scaffold is elevated more than seven feet above the ground, grade, floor or
					 equivalent surface, such platform shall be provided with a safety railing
					 constructed and installed in compliance with this Part (rule).

Current through Register Vol. 46, No. 28, July 10, 2024
(a) Permissible scaffold height. The
					 elevation of working platforms of trestle and extension trestle ladder
					 scaffolds shall not exceed 20 feet above the ground, grade, floor or equivalent
					 surface.

					 tops of such trestle or extension trestle ladders shall be tied in to the
					 building or other structure. Such tie-ins shall be by means of rigid bracing,
					 chains or ropes fastened securely to substantial, firm anchorages. Where such
					 anchorages are unavailable or where such tie-ins are impossible and there is no
					 adjacent wall, the bases of such trestle ladders shall be extended
					 perpendicularly to the length of the working platform such distance as to
					 provide a base dimension of not less than one-quarter of the height of the
					 scaffold platform above such base.
(c) Scaffold platforms. Working platforms
					 between trestles shall be equal to the width of the rungs of the extension.
					 Where ladder type platforms are used, such platforms shall comply with the
					 requirements listed in Table XIII of this Subpart.
(d) Limitations of use. Trestle and extension
					 trestle ladder scaffolds shall be used only for interior painting, decorating,
					 light maintenance or similar work. Such scaffolds shall not be used for
					 exterior work nor for work in which the equipment, supplies or materials
					 required may hamper or endanger the persons on such scaffolds.
