§1926.450 – Scope, application and definitions applicable to this subpart
§1926.450(a)
This subpart applies to all scaffolds used in workplaces covered by this part. It does not apply to crane or derrick suspended personnel platforms. The criteria for aerial lifts are set out exclusively in §1926.453.
§1926.450(b)
Boatswains’ chair means a single-point adjustable suspension scaffold consisting of a seat or sling designed to support one employee in a sitting position.
Bricklayers’ square scaffold means a supported scaffold composed of framed squares which support a platform.
Carpenters’ bracket scaffold means a supported scaffold consisting of a platform supported by brackets attached to building or structural walls.
Masons’ adjustable supported scaffold (see “Self-contained adjustable scaffold”).
Masons’ multi-point adjustable suspension scaffold means a continuous run suspension scaffold designed and used for masonry operations.
Personal fall arrest system means a system used to arrest an employee’s fall. It consists of an anchorage, connectors, a body belt or body harness and may include a lanyard, deceleration device, lifeline, or combinations of these.
Rated load means the manufacturer’s specified maximum load to be lifted by a hoist or to be applied to a scaffold or scaffold component.
Self-contained adjustable scaffold means a combination supported and suspension scaffold consisting of an adjustable platform(s) mounted on an independent supporting frame(s) not a part of the object being worked on, and which is equipped with a means to permit the raising and lowering of the platform(s). Such systems include rolling roof rigs, rolling outrigger systems, and some masons’ adjustable supported scaffolds.
Stonesetters’ multi-point adjustable suspension scaffold means a continuous run suspension scaffold designed and used for stonesetters’ operations.
Tank builders’ scaffold means a supported scaffold consisting of a platform resting on brackets that are either directly attached to a cylindrical tank or attached to devices that are attached to such a tank.
Top plate bracket scaffold means a scaffold supported by brackets that hook over or are attached to the top of a wall. This type of scaffold is similar to carpenters’ bracket scaffolds and form scaffolds and is used in residential construction for setting trusses.

(a) The following tables, and the tables in part 2 — Specific guidelines and tables, assume that all load-carrying timber members (except planks) of the scaffold are a minimum of 1,500 lb-f/in2 (stress grade) construction grade lumber. All dimensions are nominal sizes as provided in the American Softwood Lumber Standards, dated January 1970, except that, where rough sizes are noted, only rough or undressed lumber of the size specified will satisfy minimum requirements.

Because of their prefabricated nature, no additional guidelines or tables for these scaffolds are being adopted in this Appendix.
(d) Plasterers’, decorators’, and large area scaffolds.
The guidelines for pole scaffolds or tube and coupler scaffolds (Appendix A (a) and (b)) may be applied.
(1) Brackets shall consist of a triangular-shaped frame made of wood with a cross-section not less than 2 inches by 3 inches, or of 11⁄4 inch × 11⁄4 inch × 1⁄8 inch structural angle iron.
No specific guidelines or tables are given.
(i) Outrigger scaffolds (single level).
Wood poles shall not exceed 30 feet in height. Maximum intended load — 500 lbs between poles; applied at the center of the span. Not more than two employees shall be on a pump jack scaffold at one time between any two supports. When 2 × 4’s are spliced together to make a 4 × 4 inch wood pole, they shall be spliced with “10 penny” common nails no more than 12 inches center to center, staggered uniformly from the opposite outside edges.
Maximum intended load — 25 lb/ft2. However, not more than two employees shall occupy any platform at any one time. Maximum span between supports shall be 8 feet.
Not more than one employee shall occupy a window jack scaffold at any one time.
Crawling boards shall be not less than 10 inches wide and 1 inch thick, with cleats having a minimum 1 × 11⁄2 inch cross-sectional area. The cleats shall be equal in length to the width of the board and spaced at equal intervals not to exceed 24 inches.
(n) Step, platform, and trestle ladder scaffolds.
No additional guidelines or tables are given.
Maximum intended load — 250 lbs. Wood seats for boatswains’ chairs shall be not less than 1 inch thick if made of non-laminated wood, or 5⁄8 inches thick if made of marine quality plywood.
(1) In addition to direct connections to buildings (except window cleaners’ anchors) acceptable ways to prevent scaffold sway include angulated roping and static lines. Angulated roping is a system of platform suspension in which the upper wire rope sheaves or suspension points are closer to the plane of the building face than the corresponding attachment points on the platform, thus causing the platform to press against the face of the building. Static lines are separate ropes secured at their top and bottom ends closer to the plane of the building face than the outermost edge of the platform. By drawing the static line taut, the platform is drawn against the face of the building.

Reinforcing strip (minimum) A 1⁄8 × 7⁄8-inch steel reinforcing strip shall be attached to the side or underside, full length.
1⁄4 in 1⁄4 in.
(1) Multi-point adjustable suspension scaffolds and stonesetters’ multi-point adjustable suspension scaffolds. No specific guidelines or tables are given for these scaffolds.
(2) Masons’ multi-point adjustable suspension scaffolds. Maximum intended load — 50 lb/ft2. Each outrigger beam shall be at least a standard 7 inch, 15.3 pound steel I-beam, at least 15 feet long. Such beams shall not project more than 6 feet 6 inches beyond the bearing point. Where the overhang exceeds 6 feet 6 inches, outrigger beams shall be composed of stronger beams or multiple beams.
No additional guidelines or tables are being given for these scaffolds.
Stability test as described in the ANSI A92 series documents, as appropriate for the type of scaffold, can be used to establish stability for the purpose of §1926.452(w)(6).
