OSHA 10-Hour Construction ReviewScaffoldsMedium
A worker is inspecting a scaffold for damage before use. Which of the following conditions would require the scaffold to be immediately taken out of service and repaired or replaced?
- AA crossbrace with a visible crack
- BA plank with a small, superficial scratch
- CSlight discoloration of a wooden plank
- DMinor surface rust on a metal component
Show answer & explanationAnswer & explanation
Correct answer: A. A crossbrace with a visible crack
Any structural defect such as a crack, bend, or severe corrosion that compromises the integrity or load-bearing capacity of a scaffold component requires the scaffold to be immediately removed from service until repaired or replaced. A visible crack in a crossbrace is a significant structural defect.
Why the other options are wrong
- B. A small, superficial scratch on a plank is generally not a structural defect that warrants immediate removal from service.
- C. Slight discoloration of a wooden plank usually does not affect its structural strength.
- D. Minor surface rust, while noted, typically does not immediately compromise structural integrity to the point of requiring immediate removal from service unless severe.
Scaffold Structural Defects
Any damage that compromises the strength, stability, or integrity of a scaffold component renders it unsafe and requires immediate action.
- Cracks, bends, or missing components are critical defects.
- Damaged components must be repaired or replaced before reuse.
- Scaffolds with defects must be tagged 'DO NOT USE' and removed from service.
- Regular inspections are crucial for identifying defects.
