OSHA 10-Hour Construction ReviewScaffoldsHard
A construction company is using a two-point adjustable suspension scaffold (swing stage) for facade work. OSHA requires that each suspension rope be capable of supporting what minimum load?
- ASix times the scaffold's rated load
- BTwo times the scaffold's rated load
- CEight times the scaffold's rated load
- DFour times the scaffold's rated load
Show answer & explanationAnswer & explanation
Correct answer: A. Six times the scaffold's rated load
For two-point adjustable suspension scaffolds (swing stages), OSHA requires that each suspension rope be capable of supporting at least 6 times the maximum intended load applied or transmitted to that rope. This is a higher safety factor than for the scaffold structure itself (4:1).
Why the other options are wrong
- B. Two times the rated load is insufficient for suspension ropes.
- C. Eight times the rated load is a higher factor than required by OSHA for this specific component.
- D. Four times the rated load is the general requirement for scaffold structural components, but not for suspension ropes on swing stages.
Suspension Scaffold Rope Capacity
Suspension ropes for two-point adjustable scaffolds (swing stages) must have a very high safety factor to prevent catastrophic failure.
- Each suspension rope must support 6 times the maximum intended load.
- This higher factor accounts for dynamic loading, wear, and potential single-point failure.
- Applies specifically to two-point adjustable suspension scaffolds.
- Inspections of ropes are critical before each use.
