§ 6.1. Definitions.

 The following words and terms, when used in this chapter, have the following meanings, unless the context clearly indicates otherwise:

   Brace—A tie that holds one point in a fixed position with respect to another point. Bracing is a system of braces or ties that prevent distortion of a structure.

   Bracing—All temporary devices required to be used or installed during construction, repair or revision operations for the purpose of holding in place components of a building or a structure until it and all its components are permanently assembled and connected in ways that insure permanent stability. This term shall include but not be limited to braces, shores, struts, ties, forms, centering, walers, cross arms and any other devices which temporarily hold components in place during the construction of a structure.

   Bricklayers’ squares scaffold—A scaffold, the platform of which is composed of boards supported by ‘‘jacks’’ or ‘‘squares’’ secured to each other by double diagonal bracking.

   Carpenters’ bracket scaffold—A scaffold, the platform of which is composed of boards supported by brackets or that are secured to the side of the building.

   Crawling board or Chicken ladder—A board to which cross strips are nailed or otherwise fastened for use on a ladder.

   Guardrail—A rail 34 inches in height, erected to protect the workmen as well as to prevent the falling of material from a platform.

   Horse scaffold—A scaffold, the platform of which is supported by horses.

   Independent scaffold—A scaffold supported from the base by a double row of uprights, independent of support from the walls and constructed of uprights, ledgers, horizontal platform bearers and diagonal bracing. An independent pole scaffold may also be referred to as a built-up scaffold.

   Ladder jack scaffold—A scaffold, the platform of which is supported by jacks attached to ladders.

   Lanyard—A rope, webbed belt or equivalent, suitable for supporting one person. One end is fastened to a safety belt or harness and the other end is secured to a substantial object or a lifeline.

   Ledger and stringer—A scaffold member which extends horizontally from post to post, at right angles to the putlogs, supports the putlogs, forms a tie between the posts, and becomes a part of the scaffold bracing. Ledgers which do not support putlogs are also called stringers.

   Lifeline—A rope, or cable, to which a lanyard, safety belt or harness is attached.

   Needle beam scaffold—A scaffold consisting of a plank platform which rests upon two parallel horizontal beams (needle beams) supported at the ends by ropes.

   Outriggers’ scaffold—A scaffold, the platform of which is supported by projecting beams or ‘‘thrustouts’’ that extend from the wall of the building and are firmly held and secured to the framework or flooring inside the building.

   Painters’ swinging scaffold—A scaffold, the platform of which is suspended or swung from overhead supports, and rests on hangers of either iron or steel.

   Plasterers’ and decorators’ inside scaffold—A scaffold for use on light work inside a building, the platform of which is supported by ladders, steps or trestles.

   Putlog or Bearer—A scaffold member upon which the platform rests. In a single pole scaffold the outer end of the putlog rests on a ledger and the inner end rests in the wall. In an independent pole scaffold each end of the putlog rests on a ledger. In an independent pole scaffold a putlog is known as a bearer.

   Roofing bracket—A bracket (jack) used for shingling and roofing, having sharp points that are thrust into the roof to prevent sliding, or supported by means of ropes passing around or over some permanent or solidly secured object.

   Runway—A stationary incline provided as a means of ascent and descent from one level to another.

   Safety belt—A device usually worn around the waist which, by reason of its attachment to a lanyard and lifeline or a structure, acts to prevent a worker from falling.

   Scaffold—An elevated platform used for supporting workmen or materials in the course of the constructing, altering, repairing, wrecking, painting, cleaning or painting of buildings, or other construction work.

   Single pole scaffold—A platform resting on putlogs or crossbeams, the outer ends of which are supported on ledgers secured to a single row of posts or uprights and the inner ends on a wall or holes in a wall.

   Suspended scaffold—A scaffold, the platform of which is suspended from overhead supports by means of cables or steel ribbons and is adjustable.

   Temporary floor—A floor constructed for use during building operations only.

   Toeboard—A board six inches in height, erected at right angles to the platform and tightly against it to protect the workmen as well as to prevent the falling of material from a platform.
