(b) Scaffolds shall be braced by cross braces or diagonal braces, or both, for securing vertical members together laterally. The cross braces shall be of a length that will automatically square and align vertical members so the erected scaffold is always plumb, square, and rigid.

(c) Spacing of panels or frames shall be consistent with the loads imposed. The frames shall be placed one on top of the other with coupling or stacking pins to provide vertical alignment of the legs.

(d) Where uplift may occur, panels shall be locked together vertically by pins or other equivalent means.
