In plain words:

Employers must build outrigger scaffolds so the inboard end of each outrigger beam is not less than one and one-half times the outboard end in length, with I-beam or channel webs vertical and the fulcrum on secure bearings at least 6 inches in each horizontal dimension. Beams must be secured, braced and anchored, platforms fastened to outriggers, and the scaffold designed by a registered professional engineer and built and loaded to that design.
