OSHA 10-Hour Construction ReviewScaffoldsMedium
A worker is inspecting the ropes of a suspension scaffold. Which of the following conditions would require the rope to be immediately removed from service?
- APresence of dirt or dust on the rope surface
- BNoticeable reduction in rope diameter
- CSlight discoloration from weather exposure
- DMinor abrasion on the outer strands
Show answer & explanationAnswer & explanation
Correct answer: B. Noticeable reduction in rope diameter
A noticeable reduction in rope diameter indicates internal damage or excessive wear, which significantly compromises its strength and requires immediate removal from service for safety.
Why the other options are wrong
- A. Dirt or dust should be cleaned, but does not inherently mean the rope is structurally compromised and needs immediate removal.
- C. Slight discoloration, if superficial, typically does not warrant immediate removal unless accompanied by other damage.
- D. Minor abrasion might require monitoring or repair, but not necessarily immediate removal unless it compromises structural integrity.
Suspension Scaffold Rope Inspection
Key indicators of damage or wear that necessitate the immediate removal of suspension scaffold ropes from service.
- Check for reduction in diameter
- Look for broken or cut fibers
- Inspect for heat damage or chemical exposure
Memory trick: Diameter drop, safety stop!
