Meet these requirements when using catenary scaffolds.

(1) You must make sure catenary scaffolds have:
(a) No more than one platform between consecutive vertical pickups; and
(b) No more than two platforms per scaffold.
(2) You must make sure any platform that's supported by wire ropes has hook-shaped stops placed at each end of the platform that will prevent it from falling if one of the horizontal wire ropes breaks.
(3) You must make sure wire ropes are:
(a) Continuous and without splices between anchors; and
(b) Not tightened to the point that putting a load on the scaffold will overstress them.
For specific fall protection requirements for employees on catenary scaffolds, go to WAC 296-874-20056.
