A suspended platform may be used as a cantilevered s
27、ection on one end only or on both ends. 3.3 FABRICATED PLATFORM (ONE-PERSON) A manufactured plank of either an extension or xed length type used for supporting one worker and material. These platform units are usually used with ladder jacks, trestle, extension trestle, platforms, or stepladders (als
28、o known as a decorator plank). 3.4 FABRICATED PLATFORM (TWO-PERSON) A manufactured plank used for supporting two workers and material. These platform units are usually employed with ladder jacks, trestle, extension trestle, platforms, or stepladders (also known as a scaffold plank). 3.5 FABRICATED P
29、LATFORM (THREE-PERSON) A manufactured platform used for supporting up to three workers and material (also known as a stage platform). These platform units are usually used with: a) Stirrups as part of a suspension scaffold or as a scaffold runner board, b) A bridge scaffold in building or bridge tru
30、ss work, or c) Freestanding scaffold tower. 3.6 FABRICATED TUBULAR FRAME SCAFFOLD A pair of welded tubular end frames that are assembled with bracing to form a scaffold. 3.6 added March 31, 2010 3.7 GUARD RAIL A barrier secured to uprights and erected along the exposed or open side and ends of a pla
31、tform. 3.8 MIDRAIL A barrier approximately midway between the guard rail and platform decking. 3.8 added March 31, 2010 3.9 MOBILE WORK STAND A stand alone prefabricated portable scaffold unit that is used for interior work.

A modular stage platform is capable of being used with: a) Stirrups as part of a suspended scaffold; b) A bridge scaffold in b
34、uilding or bridge truss work; or MARCH 31, 2010 FABRICATED SCAFFOLD PLANKS AND STAGES - UL 1322 6UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL c) Independent scaffold tower. 3.10 revised March 31, 2010 3.11 MODULAR SUSPENDED PLATFORM A fab
35、ricated suspended platform that is used as a single unit or can be assembled with two or more platform sections.
