Section 23-5.8 - All suspended scaffolds

(a) Inspection before installation. All load-carrying parts or components and means of suspension including adequacy of anchorage or support of every suspended scaffold shall be inspected before such scaffold is installed.

(b) Suspension from roof hooks or irons. No parapet, curtain wall or similar portion of a building or other structure shall be used to support the roof hooks or irons of any suspended scaffold unless a professional engineer licensed to practice in the State of New York certifies that such parapet, curtain wall or similar portion of a building or other structure is adequate to support the loads intended to be imposed thereon. Such certification shall be kept on the job site available for examination by the commissioner.

(c) Installation and use.

(1) The installation or horizontal change in position of every suspended scaffold shall be in charge of and under the direct supervision of a designated person.

(2) The horizontal displacement of any suspended scaffold platform in a direction perpendicular to the face of a building or other structure by means of an applied horizontal force shall not exceed one-tenth of the vertical distance from the elevation of the scaffold platform to its point of suspension. Any person who applies such horizontal force to a scaffold platform while he is located on any portion of the building or other structure at a point more than 10 feet above the ground, grade or equivalent surface shall be provided with and shall use an approved safety belt with a lifeline in compliance with this Part (rule).

(d) Hoisting machines.

(1) Any manual or power-operated hoisting machine used for suspended scaffolds shall be approved.

(2) A block and tackle shall not be construed to be a hoisting machine and is not required to be approved.

(3) At least four turns of the suspension wire rope shall at all times remain on the drum. The end of such rope shall be properly secured to the drum. The foregoing requirement does not apply to traction type hoists.

(e) Fibre rope. Fibre ropes used with suspended scaffolds shall be first grade manila hemp or its equivalent in strength. Blocks shall be of a size to fit the ropes.

(f) Limited use of fibre rope.

(1) Fibre rope shall not be used for or near any work involving the use of corrosive substances or chemicals.

(2) Fibre rope shall not be used as a means of suspension in lengths exceeding 100 feet between blocks.

(3) Fibre rope shall not be used on hoisting drums.

(g) Tie-ins. Every suspended scaffold shall be tied in to the building or other structure at every working level. Window cleaners' anchors shall not be used for such tie-ins and other means shall be provided.

(h) Scaffold platform. The planking of every suspended scaffold platform shall overlap its support in compliance with this Part (rule). Such planking shall be either nailed in place or otherwise secured against displacement. Where such planks rest directly upon stirrups without any intermediate supporting frames, they shall be secured together by means of cleats nailed to the undersides at intervals not exceeding four feet. Cleats or other equivalent means shall be provided on each side of the supporting stirrups under the planks to prevent sliding or any movement of the planks.
