Current through Register Vol. 46, No. 28, July 10, 2024
(a)
					 Platform planking. Scaffold platforms for manually-propelled mobile scaffolds
					 shall be tightly planked for the full width of the scaffolds except for
					 necessary access openings. Such planking shall consist of planks not less than
					 two inches thick full size, exterior grade plywood at least three-quarters inch
					 thick or material of equivalent strength.
(b) Safety railings required. The platform of
					 every manually-propelled mobile scaffold shall be provided with a safety
					 railing constructed and installed in compliance with this Part
					 (rule).
(c) Platform access. A
					 ladder or stairway shall be provided for proper access to every
					 manually-propelled mobile scaffold. Such ladder or stairway shall be affixed to
					 or built into the scaffold and so located that when in use it will not have a
					 tendency to tip the scaffold. Landing platforms shall be provided at intervals
					 not to exceed 35 feet.
(d) Scaffold
					 height. For any free-standing manually-propelled mobile scaffold the ratio of
					 the platform height above the ground, grade, floor or equivalent surface to the
					 minimum base dimension shall assure scaffold stability when in use, but in no
					 case shall such height be more than four times the minimum base
					 dimension.
(e) Casters. Casters
					 shall be properly designed for strength and dimensions to support four times
					 the maximum load intended to be imposed thereon. All casters shall be provided
					 with positive locking devices to hold the scaffolds in position.
(f) Scaffold bracing. Manually-propelled
					 mobile scaffolds shall be properly braced by cross-bracing or diagonal-bracing,
					 or both, to secure vertical members together laterally. Cross-braces shall be
					 of such length as will automatically square and align vertical members so that
					 the erected scaffold is always plumb, square and rigid. All brace connections
					 shall be made secure.
(g) Scaffold
					 footing. Whenever any such scaffold is in use and is occupied by any person,
					 such scaffold shall rest upon a stable footing, the platform shall be level and
					 the scaffold shall stand plumb. All casters or wheels shall be locked in
					 position.
(h) Moving the scaffold.
					 Provisions shall be made to prevent such scaffolds from tipping or falling
					 during their movement from one location to another. Scaffolds shall be moved
					 only on level floors or equivalent surfaces free from obstructions and
					 openings. No person shall be suffered or permitted to ride on any
					 manually-propelled mobile scaffold while it is being moved.
(i) Bridging prohibited. Bridging between two
					 or more manually-propelled mobile scaffolds or between any such scaffold and
					 other supports is prohibited.
