Current through Register Vol. 54, No. 28, July 13, 2024
(a)
Fixtures and appliances.
Only approved scaffold machines shall
				  be used in the erection and use of any scaffold. Where scaffold machines are
				  rented, all the fixtures and appliances received with them shall be erected and
				  used at all times when such scaffolds are in service. The moving parts of
				  scaffold machines shall be frequently inspected and shall be exposed to view at
				  all times so that possible defects may be readily detected, but such moving
				  parts shall be railed off or otherwise guarded to protect workmen from coming
				  into contact with them.
(b)
Suspended scaffolds recommended.
The use of a suspended
				  scaffold is recommended for all buildings more than five stories high, built
				  with a frame to provide overhead support. The parts of the building or
				  structure to which a suspended scaffold is attached shall be examined to
				  determine if such parts are of sufficient strength to support properly the load
				  that may be imposed on the scaffold.
(c)
Safety factor.
A
				  suspended scaffold shall be capable of sustaining a working load of 40 pounds
				  per square foot with a factor of safety of four.
(d)
Suspension supports.
When cables are used they shall conform to the requirements set forth in §
										6.31 (relating to cables, ropes,
				  block and tackle). Where steel ribbons or suspension supports other than cables
				  are used, they shall possess a factor of safety in strength of at least
				  eight.
(e)
Thrustouts.
Thrustouts shall consist of steel I-beams or, in
				  the case of the overhand type of machine, steel channel beams, which project at
				  least one foot beyond the outer edge of the suspended platform, and shall be
				  securely anchored and fastened to the steel frame work of the building by means
				  of U-bolts and anchor plates tightened by the use of jam or lock nuts or, where
				  building conditions prevent, by other approved equally effective means. I-beam
				  thrustouts shall be equipped with a stop bolt rigidly fastened and of adequate
				  size to prevent the shackle from slipping over the edge of the beam. Channel
				  beam thrustouts shall be parallel and secured to each other by a bolt at least
				  3/4 inch in diameter over which thimbles of iron pipe shall be slipped to keep
				  the beams the necessary distance apart.
(f)
Putlogs.
Putlogs shall
				  be securely fastened to the scaffold fixtures and spaced not more than 8 feet
				  apart.
(g)
Platforms.
Platform planks shall be laid so that their edges
				  abut and fit "tight." Planks shall be not less than 10 inches wide and 2 inches
				  thick. The platform planks shall overlap putlogs by at least 1 foot but not
				  more than 2 feet at the ends of the scaffold.
(h)
Prevention of swaying.
Ropes or hooks shall be used and fastened to the platform of the scaffold and
				  to the building in such a manner and at such intervals as to prevent the
				  scaffold from swinging away from the building. Likewise, fenders shall be
				  provided to prevent the scaffold from swinging against the building.
(i)
Protection.
Protection
				  shall be afforded as set forth in §
										6.32 (relating to
				  protection).
