A supported scaffold is being reviewed before masonry crews load plank with workers and materials. What capacity factor applies to the scaffold and its components?
Correct Answer
D) Four times the maximum intended load
Each scaffold and scaffold component must support its own weight and at least four times the maximum intended load applied or transmitted to it. Other choices are below the OSHA scaffold capacity requirement.
Why This Is the Correct Answer
Each scaffold and scaffold component must support its own weight and at least four times the maximum intended load applied or transmitted to it. Other choices are below the OSHA scaffold capacity requirement.
Why the Other Options Are Wrong
Option A: Select equal to the intended load for scaffold capacity
Choice A gives Equal to the intended load. Its specific error: it leaves out the controlling Scaffold capacity result: Four times the maximum intended load.
Option B: Apply the Two times the intended load limit to the scaffold capacity check
Choice B (Two times the intended load) is rejected because the choice would not get the project to Four times the maximum intended load, which is the Scaffold capacity result verified by the source. The cited answer is Four times the maximum intended load.
Option C: Treat Three times the intended load as the controlling scaffold capacity result
In general project requirements, Three times the intended load is the wrong selection for Scaffold capacity: the option does not produce the required Scaffold capacity outcome, Four times the maximum intended load.
Memory Technique
Make scaffold capacity a tabbed card: cite the exact condition, then choose Four times the maximum intended load.
Reference Hint
Open 29 CFR 1926 OSHA Construction Standards; use 29 CFR 1926.451(a)(1) to confirm that Each scaffold and scaffold component must support its own weight and at least four times the maximum intended load applied or transmitted to it.
