Section 23-5.11 - Needle beam scaffolds

(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.

(e) Containers for tools. Suitable containers for tools, bolts and similar objects shall be provided for every needle beam scaffold. Such containers shall be securely attached to the scaffolds.
