					 beams, or girders of floors below the floor or level where any work is being
					 done, or about to be done, covered with flooring laid close together, or with
					 other suitable material to protect workers engaged in such building from
					 falling through joists or girders, and from falling substances, whereby life or
					 safety is endangered.

					 three-inch planks without an intermediate beam. The intermediate beam shall be
					 of a sufficient strength to sustain a live load of 50 pounds per square foot of

					 stonemasons, concrete workers, or other trades using heavy tools or storing
					 heavy material on the scaffold shall be constructed as follows:
(See Plate B-19, Appendix):
(b) When buggies are used on scaffolds to

					 point on girders, beams, or planking.
(c) Uprights. For heights not to exceed 20
					 feet, the uprights shall be of 4-inch by 4-inch lumber or heavier material,
					 with a space of 4 feet between uprights at right angle to the wall and not more

					 4-inch uprights shall be made with square butt joints, and scabs of 2-inch by
					 4-inch material at least 48 inches long shall be nailed in place on 2 sides
					 with 6 nails in each ½ of each scab. Uprights laminated from 2-inch by

					 attachment points. If the uprights rest on a surface that might cause slipping,
					 a continuous sill or other means shall be provided to hold the uprights in
					 place. When the scaffold is resting on earth or other such material, the

					 by 6-inch board, 1 being on each side of the uprights and fastened securely at
					 each point of support.
(2) Ribbons
					 shall be 1-inch by 6-inch or heavier material securely fastened to both inside
					 and outside uprights directly under and in contact with the ledgers. Vertical
					 spacing of ribbons and ledgers shall not exceed 7 feet. Ribbons shall be long

					 for use by bricklayers, stonemasons, or other heavy trades shall be made of
					 "selected lumber," or better. Those of the following sizes shall not project
					 more than 6 feet beyond the outer support; shall be securely anchored and
					 braced to prevent tipping or turning; and shall be spaced at centers of 7 feet
					 6 inches, or closer.
The inboard end of outrigger beams, measured from the
						fulcrum point to anchorage point, shall not be less than 1 ½ times the
						outboard end in length. The fulcrum point of the beam shall rest on a secure
						bearing at least 6 inches square.
(2) On continuous scaffolds, where the beams
					 may receive load from work platforms on each side, such beams shall not be less
					 than 3 inches by 16 inches in cross section. For single scaffolds, consisting
					 of a platform between 2 beams, the outrigger beams may have a smaller cross
					 section, but not less than 3 inches by 12 inches. The platforms shall consist
					 of planks, at least 2 inches by 10 inches, covering the full width of the
					 projection. Planking shall be nailed or bolted or otherwise secured to
					 outriggers.
The ends of the planks shall not project more than 18
						inches beyond the outrigger, and not less than 6 inches, unless they are nailed
						in place. Every outrigger scaffold 7 ½ feet or more in height shall be
						provided with a railing and toeboard. The top rail shall consist of double
						2-inch by 4-inch members. One member shall be fastened in a flat position on
						top of the posts and the other member shall be fastened in an edge-up position
						to the inside of the posts and at the side of the top rail.
Additional protection in the form of screen enclosing the
						opening between rail and toeboard shall be provided if material on the scaffold
						is piled higher than the toeboard.
(3) Where additional working levels are
					 required to be supported by the outrigger method, the plans and specifications
					 of the outrigger and scaffolding structure shall be prepared by a Civil
					 Engineer currently registered in California.

					 free-standing tower or rolling scaffold shall not be less than 1/3 the height
					 of the scaffold unless such scaffold is securely guyed or tied. For
					 restrictions when worker rides scaffold see paragraph (i) following.
(b) Construction and Erection.
(1) The uprights, ledgers, ribbons, braces,
					 and splices shall be equivalent to the standards specified in other applicable
					 Sections of these Orders. Railings are required if the platform is 7 ½
					 feet or more above grade. Railings shall be installed in accordance with the
					 provisions of Section
					 1644(a)(6).
NOTE: Toeboards or side screens may also be required.

					 shimming of horse ledgers to obtain added height is prohibited.
(5) Horses or parts which have become weak or
					 defective shall not be used.
(6)
					 When horse legs are extended by splicing, the joints must be butt-ended, and
					 scabs not less than 18 inches long and of the same cross section as the leg
					 shall be nailed on each side of the joint. As an alternative, new legs of
					 adequate length may be installed, provided that they completely overlap the
					 original legs and are well secured to them from top to bottom. Vertical
					 extensions shall not be used to extend height of metal folding horses if the
					 stability of the horse is impaired.

					 not less then 3 feet wide and 6 feet long, made of ¾ inch plywood,
					 equivalent to Douglas Fir Plywood Association Grade A-A Exterior.
(2) Under the platform, there shall be 2
					 supporting bearers made from 2-inch by 4-inch "selected lumber," or better.
					 They shall be free of knots or other flaws and project 6 inches beyond the
					 platform on both sides. The ends of the platform shall extend about 6 inches
					 beyond the outer edges of the bearers. Each bearer shall be fastened to the
					 platform by at least two ½ inch-diameter bolts.

					 inch by 1 ½ inches, or equivalent, shall be placed around all sides of
					 the platform to prevent tools from rolling off.
(4) Supporting ropes shall be 1-inch-diameter
					 Manila rope, or equivalent, free from deterioration, chemical damage, flaws, or
					 other imperfections. Rope connections shall be such that the platform cannot
					 shift or slip. If two ropes are used with each float, they shall be arranged so

					 support. Each of the two supporting ropes shall be hitched around one end of a
					 bearer and pass under the platforms to the other end of the bearer where it is
					 hitched again, leaving sufficient rope at each end for the supporting
					 ties.
(5) Each employee working
					 from a float scaffold shall be provided with and use fall protection in
					 accordance with the requirements of Article 24.

					 Planks shall be at least 14 inches wide and consist of "structural plank" or
					 the equivalent.
(b) Wire ropes
					 shall not be tightened to the extent that the application of a scaffold load
					 may overstress them.

						used every 50 feet to pick up the sag of the wire rope. Cables shall be
						continuous without splices between anchors.
(c) A safety factor of at least 6 shall be
					 used in determining the size of wire rope to be used.
(d) The wire rope manufacturer's
					 recommendations with respect to the number and spacing of clamps shall be

					 Construction Safety Orders.)
(f) A
					 safe means of access and egress shall be provided to the stage at all
