(a) Scope and
					 Application.
This section applies to work directly associated with the
						framing of new buildings or structures using the operations, methods, and
						procedures associated with residential-type framing activities, i.e., joists or
						trusses resting on stud walls.
(b) Definitions.
(1) Bottom Plate. The bottom horizontal
					 member of a frame wall. Sometimes called the "sole plate."
(2) Eaves. The lowest edge of a sloped
					 roof.
(3) Fascia Board. The
					 exterior trim board at the perimeter of the roof.
(4) Joist. One of a series of parallel beams
					 used to create a structural support system for a floor deck or flat roof, onto
					 which sheathing is fastened.
(5)
					 Nominal Size. For purposes of this section, the commercial size designation of
					 a standard width and depth of standard sawn lumber and glue laminated lumber
					 grades; larger than the standard actual net size of the finished, dressed
					 lumber. An approximate rough-cut dimension assigned to a piece of material as a
					 convenience in referencing to the piece, such as "2 x 4".
(6) Rafter. One of a series of structural
					 members of a roof designed to support roof loads. A framing member that runs up
					 and down the slope of a pitched roof. The beams that slope from the ridge of a
					 roof to the eaves and make-up the main body of the roof's framework. The
					 rafters of a flat roof are sometimes called roof joists.
(7) Residential-type Framing Activities. For
					 the purposes of this section, residential-type framing activities include:
					 installation of floor joists, floor sheathing, layout and installation of
					 walls, hanging and nailing of shear panels, setting and bracing roof trusses
					 and rafters, installation of starter board, roof sheathing, and fascia board;
					 installation of windows, siding and exterior trim.
(8) Roof Slope. For the purposes of this
					 section, the incline angle of a roof surface, given as a ratio of the vertical
					 rise to the horizontal run. A 7:12 roof has 7 feet of vertical rise for 12 feet
					 of horizontal run.
(9) Sheathing.
					 The structural panel covering fastened onto studs, floor joists, and/or
					 rafters/trusses.
(10) Slide Guards.
					 A 2-inch nominal cleat, on centers not to exceed 4 feet, securely fastened to
					 the roof sheathing to provide footing on a sloped roof.
(11) Starter Board. The board-type sheathing
					 material installed at eaves and gable ends in the plane of the sheathing and
					 visible from the underside.
(12)
					 Stud. A vertical framing member in walls and partitions, also referred to as a
					 wall stud, attached to the horizontal sole plate below and the top plate
					 above.
(13) Top Plate. Top
					 horizontal member of a frame wall supporting ceiling joists, rafters, or other
					 structural members.
(14) Truss.
					 Prefabricated structural roof unit consisting of triangular bracing (truss
					 webs) between the ceiling joist (bottom chord) and the roof rafter (top chord)
					 commonly installed parallel with other trusses to create a structural support
					 system for a roof after which sheathing is fastened. The bottom chord often
					 serves as a ceiling joist. Each member is usually subjected to longitudinal
					 stress only, either tension or compression.
(15) Truss Support Plate. A temporary support
					 structure erected near mid-span of an area with a large open span, such as a
					 garage, to support trusses during installation.
