SafetyCâu 649 / 700
A supported scaffold and its components are being specified. Each part of the scaffold and its supports must be capable of holding at least how many times the maximum intended load without failure?
a.2 times
b.4 times
c.6 times
d.10 times
Giải thích
Correct: scaffolds and their components must support at least 4 times the maximum intended load. A 2:1 ratio is the criterion for a non-engineered fall-arrest anchorage, not scaffold capacity. Suspension ropes carry a 6:1 factor, but that applies to the rope, not the overall scaffold structure. 10 times is not the general scaffold requirement.
