(a) Staging supported by wire rope shall have hook-shaped stops on each end of staging members so as to prevent them from slipping off the wire ropes. These hooks shall be so placed that they will also tend to prevent the staging members from falling if one wire rope breaks. Planks shall be at least 14 inches wide and consist of "structural plank" or the equivalent.
(b) Wire ropes shall not be tightened to the extent that the application of a scaffold load may overstress them.
NOTE: It is suggested that a hanger or set of falls be used every 50 feet to pick up the sag of the wire rope. Cables shall be continuous without splices between anchors.
(c) A safety factor of at least 6 shall be used in determining the size of wire rope to be used.
(d) The wire rope manufacturer's recommendations with respect to the number and spacing of clamps shall be followed. The clamps shall be placed with the "U" on the dead end. See Plate C-2, Appendix.
(e) Standard guardrail shall be installed to protect all open sides and ends of staging or safety nets shall be installed.
In lieu of guardrails or safety nets, safety belts and lanyards shall be used, provided the lanyard is tied off to the structure or to a separate cable for this purpose. (See Article 24 of the Construction Safety Orders.)
(f) A safe means of access and egress shall be provided to the stage at all times.
