CSLB C-33 Painting & DecoratingSafetyMedium
A painting contractor is using a single-point adjustable suspension scaffold (swing stage) to paint the exterior of a multi-story building. What is the maximum number of workers permitted on this type of scaffold at one time, assuming standard capacity?
- AOne worker
- BThree workers
- CFour workers
- DTwo workers
Show answer & explanationAnswer & explanation
Correct answer: A. One worker
A single-point adjustable suspension scaffold, often called a boatswain's chair or 'spider' scaffold, is designed for one worker. It is suspended by a single rope from an overhead support and is not intended to support multiple individuals due to stability and load capacity limitations.
Why the other options are wrong
- B. Three workers exceed the capacity and stability limits for a single-point suspension scaffold.
- C. Four workers are far beyond the safe capacity for a single-point suspension scaffold.
- D. Two workers are generally permitted on two-point suspension scaffolds (swing stages), not single-point.
Single-Point Suspension Scaffold Capacity
The maximum number of workers permitted on a single-point adjustable suspension scaffold (e.g., boatswain's chair) at one time.
- Designed for individual use.
- Suspended by a single rope.
- Used for light-duty, intermittent work.
Memory trick: Single point, single person, simple solution.
