NOTE: Stone setters' adjustable multiple-point suspended
						scaffolds shall also be constructed in accordance with this Order. See Plate
						B-26, Appendix.
(a) Each outrigger
					 shall be equal in strength to at least a standard 7-inch, 15.3-pound steel at
					 least 15 feet long. It shall not project more than 6 feet 6 inches beyond the
					 bearing point and it shall be supported laterally at or near its fulcrum point.
					 Where the overhang exceeds 6 feet 6 inches, thrustouts shall be composed of
					 stronger beams or multiple beams and be installed under the supervision of a
					 person who is capable of securing a safe installation. Outriggers shall be
					 securely fastened to the structure by the equivalent of "U" bolts and anchor
					 plates, washers, and nuts. All beams shall be set with their webs vertical, and
					 they shall rest on wood bearing blocks. A stop bolt shall be placed at the
					 outer end of the outrigger to prevent suspension rope from slipping
					 off.
(b) The platform shall be
					 suspended by wire ropes capable of supporting at least 6 times the intended
					 load, properly secured to the outriggers and to each end of the bolster
					 (putlog), or to hoisting machines.
(c) Bolsters not more than 4 ½ feet
					 long between supports may be of wood, provided they are equal in strength to
					 4-inch by 6-inch "selected lumber" grade, free from damage that affects the
					 strength.
(d) The bolsters and
					 outriggers shall be spaced not more than 8 feet center to center.
(e) Platform Width. The platform shall be not
					 less than 4 feet wide and made of 2-inch by 10-inch or larger "selected lumber"
					 laid closely together and adequately secured to prevent them from slipping,
					 tipping, or collapsing.
(f) The
					 scaffold shall be as close to the wall as reasonably possible, but not more
					 than 6 inches from the wall.
(g)
					 When employees are at work on the scaffold and an overhead hazard exists,
					 overhead protection shall be provided on the scaffold, not more than 9 feet
					 above the platform, consisting of 2-inch planking, or material of equivalent
					 strength, laid tight, and extending not less than the width of the
					 scaffold.
(h) The scaffold shall be
					 capable of sustaining a working load of 50 pounds per square foot and shall not
					 be loaded in excess of that figure.
EXCEPTION: When the scaffold is designed for loads in
						excess of 50 pounds per square foot by a Civil Engineer currently registered in
						California.
(i) The use of
					 fiber rope is prohibited.
(j)
					 Toeboards and side screens shall be installed in accordance with the applicable
					 Sections of Article 16.
