Inspecting Interior Hung Scaffolds

An interior hung scaffold is a suspension scaffold consisting of a platform suspended from the ceiling or roof structure by fixed length supports.

  • Make sure interior hung scaffolds are suspended from roof structures (e.g., ceiling beams).
  • Make sure roof structures are inspected for strength before scaffolds are erected.
  • Ensure suspension ropes/cables are connected to overhead supports by shackles, clips, thimbles, or equivalent means.
  • Check bearers to ensure they have dimensions of 2 x 10 inches, and are used on edge.
  • Check for an intended maximum load of 25 to 50 lbs. per square foot when the maximum span is 10 feet.
  • Check for an intended maximum load of 75 lbs. per square foot when the maximum span is 7 feet.
