Inspecting Capacity
- Ensure scaffolds and scaffold components are capable of supporting, without failure, their own weight and at least 4 times their maximum intended load.
No more than two workers can occupy the scaffold.
- Make sure each suspension rope, including connecting hardware, is capable of supporting, without failure, at least 6 times the maximum intended load applied to that rope while the scaffold is operating at the greater of either:
- the rated load of the hoist
- 2 times the stall load of the hoist
- Inspect to ensure all suspension scaffold support devices, such as outrigger beams, cornice hooks, and parapet clamps:
- Rest on surfaces capable of supporting at least 4 times the load imposed on them by the scaffold operating at the greater of either:
- rated load of the hoist
- 1½ times the stall capacity of the hoist
- outrigger beams are installed at right angles to the face of the building and:
- secured against movement with tiebacks and or the structure; or
- by opposing angle tiebacks installed and secured to a structurally sound point of anchorage such as structural members other than vents, electrical conduit, or standpipes and other piping systems.
- they occupy no more than two employees occupy suspension scaffolds designed for a working load of 500 pounds (non-mandatory);
- they occupy no more than three employees occupy suspension scaffolds designed for a working load of 750 pounds (non-mandatory); and
- suspension scaffolds are altered only under the supervision and direction of a competent person.
