A. 6 inches

B. 9 inches

C. 12 inches

D. 15 inches

Answer:

C. 12 inches

When setting up a ground supported scaffold, it is important to ensure that the scaffold is level and stable. Leveling jacks are used to adjust the height of the scaffold legs to accommodate uneven ground. These jacks have adjustment screws that can be turned to raise or lower the scaffold.

To maintain stability and safety, there are limitations on how high the leveling jack adjustment screws can be extended. The maximum height for leveling jack adjustment screws on a ground supported scaffold is typically set at 12 inches.

Exceeding this height limit can lead to an unstable scaffold, which increases the risk of accidents and injuries. It is crucial to follow safety regulations and manufacturer guidelines to ensure proper setup and use of scaffolds.
