Larger, heavier units that require three or more workers to move a module, or that need powered assistance to be moved, are outside the scope of this standard. The scope also covers the railings provided as fall protection accessories for the platforms, stair units, ramps, and choral risers within the scope of this standard.

(2) supplied by the user or owner of the units in accordance with detailed, specific legging system specifications supplied by the platform manufacturer of the portable platform, stair unit, ramp, or choral riser. *
